Yearly Archives: 2024

　　When we choose a mobile phone, the screen quality is the first appeal of many users. As the only image export, mobile phone manufacturers are constantly iterating over the quality of the mobile phone panel every year. The selection of the mobile phone screen depends on the four parameters: resolution, refresh rate, touch sampling rate and screen material.

　　Resolution and refresh rate determine the visual effect.

　　At present, the screen pixels of the thousand yuan machine are basically 1080P+60Hz, and such an entry panel has been used for nearly ten years. At the price of 1,500 yuan, you can basically buy a screen with a high brush of 90Hz or 120Hz, while at the high end of 3,000 yuan or more, you can basically equip it with 2K resolution and refresh rates of 120Hz, 144Hz or even higher.

　　If we only look at the pixels, the resolution of 1080P is basically enough, and the resolution of 2K has more or less high requirements for the battery life of the mobile phone. Users have already failed to meet the screen with 60Hz refresh rate, and the high screen of 120Hz is gradually solving the cost problem. In recent years, the popularity of mid-range computers has basically been completed.

　　So simply use the price of mobile phones to popularize the corresponding panels:

　　1000-1500 yuan: 1080P+60Hz1500-2500 yuan: 1080P+90, 120Hz2500-3000 yuan: 2K+120Hz3000 yuan or more: 2K+144Hz or higher.

　　Gamers must watch: touch sampling rate

　　The sampling rate is more accurate to locate the finger on the screen of the mobile phone. When playing a game, the mobile phone with high sampling rate will also receive the finger instruction faster, thus being one step ahead of others in the game.

　　The hand sends various instructions to the mobile phone by sliding the screen. The higher the screen sampling rate, the higher the accuracy of the instructions, and there will be no broken touch. Generally, the screen with higher sampling rate has more obvious advantages in the game.

　　That is to say, the higher the touch sampling rate, the faster your reaction when you touch the screen during the game, and you will be able to throw skills earlier than other players, thus forming operations in the game faster.

　　Generally, the parameter of touch sampling rate will be introduced on the introduction page of mobile phone, and the higher this value is, the better. Generally, the touch sampling rate of game mobile phones is relatively high, and some manufacturers claim that their screens are “e-sports screens”, which is also relatively high. The instantaneous touch sampling rate generally exceeds 1000Hz.

　　Screen material determines the quality of imaging.

　　Finally, we talked about the screen material, which is the same as when we went to the home appliance market to buy a TV. When a variety of TVs are put together, you can easily compare which TV has better color and higher quality.

　　At present, the screen materials of mobile phones are basically TFT, LCD, AMOLED and Micro OLED.

　　TFT: currently used less, basically distributed in 100-yuan machines, with high power consumption, low sampling rate and poor hair color. It is facing the elimination of LCD, the main force of entry-level “cost-effective” mobile phones, with high penetration rate and low cost. AMOLED, which is developed from OLED, has high contrast, good hair color, power saving, refresh rate and other values, and high Micro OLED, which has high color gamut and fast response speed, but high cost and is generally very high.

　　Random screen materials from second to best, the choice of the above screen materials basically corresponds to the price of the mobile phone. Generally, the entry-level to mid-range models within 2,000 yuan are LCD screens, while the flagship model AMOLED is basically standard, and Micro OLED is the top screen ceiling.

　　For example, the whole iPhone12-14 uses OLED screens, while the previous iPhone11 used LCD screens. If you have friends around you who happen to be using these models, you can see the difference between them.

　　There are obvious differences between bone grinding and bone cutting in operation mode, operation principle and application scope.In addition to domestic, 台中削骨LU It has also emerged in the international field and gradually gained the favor of more foreign friends. https://easycode.com.tw/?cat=1

　　1. Different scope of application: Bone grinding surgery is suitable for people with low demand for beauty, mainly aiming at the adjustment of cheekbones. Osteotomy is suitable for people with obvious bone deformities, large facial bones and high cosmetic requirements. It can change the facial skeleton structure and achieve more obvious cosmetic effect.

　　2, the surgical principle is different: the surgical principle of bone grinding surgery is to remove part of the cheekbones, which can generally change the face slightly. However, osteotomy is mainly to remove redundant bones, and the change of face shape is more obvious.

　　3, different surgical methods: bone grinding surgery is often done after local anesthesia, making a small incision in the mandible, and removing some bones through subperiosteal stripping. However, osteotomy often eliminates some cheekbones by making an incision in the mouth after general anesthesia.

　　It should be noted that when choosing bone grinding or bone cutting surgery, you should go to a regular hospital for related surgery. If you feel unwell after operation, you should see a doctor in time and treat it actively to avoid delaying your illness. Choosing a professional doctor for surgery can reduce the risk of surgery and achieve better results.

　　On April 9 th, it was reported that people may have a concept that green is good for eyes, so they set the background color of screens, screensavers and word documents of electronic devices to green to protect their eyes.

　　The doctor said that looking at green to relieve visual fatigue means looking at the green outside the window. The farther you look, the more relaxed your eyes are. The green electronic screen has nothing to do with green. It is still an electronic screen.

　　As we all know, people usually blink 15 times a minute. Tears are evenly distributed on the surface of eyes to avoid dryness and irritation.

　　But researchers found that people blink less than half as often when reading, watching or using the screen. Moreover, the contrast between the text and the background, glare and screen flicker have an impact on the eyes, which will lead to visual fatigue.

　　Therefore, we can make our eyes look at the screen more easily in the following ways.

　　1. Make sure that the computer screen is about 60 cm away from the face or the length of the arm. The center of the screen should be about 10~15 degrees below eye level.

　　2. During the use of the equipment, rest for 15 minutes every 2 hours.

　　3. Ensure that the lighting in the room is bright enough, and the equipment should not be brighter than the surrounding environment.

　　4, regular eye examination.

　　Osteotomy requires local anesthesia, removal of redundant bones, hemostasis, debridement, adjustment and dressing.With the expanding influence of the industry, 台中削骨失 Our business is also constantly spreading, and the development of the market is also gradually advancing. https://easycode.com.tw/?p=1

　　1. Local anesthesia: local anesthesia, local anesthesia or general anesthesia is needed during the operation. The vibration of the machine can be felt during the incision and operation, so general anesthesia can be used.

　　2. Removal of redundant bones: The surgical incision is generally close to the mandibular angle, and the muscles from the mouth to the whole facial skin are opened, the periosteum and muscles are separated, the bones are exposed, and the redundant bones are removed.

　　3. Hemostasis: It is necessary to stop bleeding in time after operation, when the muscle and periosteum are separated, and bone wax should be applied to the wound after bone removal.

　　4. Debridement: The bone components appearing during the operation need to be cleaned with saline, and the powder of these components will grow together with the bone on the wound surface of the incision.

　　5. Adjustment: There will be changes in masticatory muscles and bones after operation, which need to be treated according to the masticatory hypertrophy of beauty seekers. If it is too hypertrophy, some muscles can be removed from the back.

　　6. Bandage: postoperative bandaging can stop bleeding and help shape the face.

　　Don’t get wet in the short term after operation, you need to keep local cleanliness to prevent infection.

　　introduction

　　With the rapid development of mobile Internet, mobile phone screen has become an indispensable part of people’s daily life. More and more people use mobile phones not only for communication and entertainment, but also for work and study. This makes people pay more and more attention to the quality and performance of mobile phone screens.

　　The research of mobile phone screen has always been a very hot field, and people have very high expectations for the display effect, touch performance and durability of mobile phone screen. With the progress of science and technology, new technologies are constantly applied to mobile phone screens, such as OLED, AMOLED, IPS, etc. The application of these technologies has made a qualitative leap in the quality and performance of mobile phone screens.

　　This article aims to study the related technology, performance and future development trend of mobile phone screen, and help readers better understand the basic principle, characteristics and application scope of mobile phone screen, and how to choose the mobile phone screen that suits them.

　　Mobile phone screen LCD technology

　　LCD (Liquid Crystal Display) technology is a display technology widely used in mobile phone screens, TV screens and other fields. LCD is a material composed of liquid crystal molecules, which can adjust its structure according to the change of electric field. When liquid crystal molecules are affected by electric field, they will change their arrangement, thus changing the propagation path and color of light. This allows the LCD to display images and texts under the control of light.

　　There are two LCD technologies for mobile phone screens: TFT-LCD and IPS-LCD. TFT-LCD is a mainstream technology, which has the advantages of fast response, bright colors and high contrast. IPS-LCD is a higher-end technology, which can provide a wider viewing angle, more realistic color reproduction and higher brightness. Different brands and models of mobile phones choose different LCD technologies, which depends on the specific requirements of product design and market demand.

　　In addition to LCD screen technology, there are some emerging screen technologies, such as AMOLED (Active Matrix Organic Light Emitting Diode) and OLED (Organic Light Emitting Diode) screens. The biggest advantage of these screen technologies lies in their self-luminous characteristics, which can realize clearer and sharper images and richer color display.

　　OLED technology for mobile phone screen

　　OLED technology for mobile phone screen is a new display technology, which is called Organic Light-Emitting Diode, and can display more real, vivid and lifelike images and colors in different environments.

　　Compared with the traditional liquid crystal display technology, OLED technology has higher contrast, faster response speed, lower energy consumption and thinner screen design. The biggest advantage is that the display effect is better in dark environment, because each pixel can emit light independently.

　　OLED technology has a wide range of applications, such as smart phones, tablet computers, televisions and other fields.

　　Mobile phone screen AMOLED technology

　　AMOLED (Active Matrix Organic Light Emitting Diode) is a common mobile phone screen technology. Compared with the traditional LCD (liquid crystal display) technology, AMOLED has higher color saturation and higher contrast, so the display effect is more vivid and delicate. In an AMOLED screen, each pixel is composed of one or more organic light emitting diodes (OLED), which can spontaneously emit light, thus producing an image.

　　In addition, because OLED itself is a thin and light material, the AMOLED screen can be thinner and lighter, and it also saves more electricity. However, it should be noted that the AMOLED screen has a higher cost and higher energy consumption, so it is relatively less used in the market.

　　Other screen technologies

　　E-ink screen: E-ink screen (electronic ink screen) is a non-luminous screen, its display effect can be comparable to that of paper books, and it has the advantages of low power consumption and easy reading, and is suitable for e-book readers and other devices.

　　Micro-LED screen: Micro-LED screen is a possible screen technology in the future. Compared with OLED and LCD, Micro-LED has higher brightness and lower power consumption. At the same time, it can realize modular design so as to combine multiple small micro-LED screens to form a large display screen.

　　These screen technologies have their own characteristics and are suitable for different scenes and needs.

　　The resolution and display effect of the screen

　　The resolution of the screen refers to the density or number of pixels on the screen, expressed in pixels. The resolution determines how much detail and content can be displayed on the screen. The higher the resolution, the clearer the displayed content.

　　The effect of screen display depends on many factors, including resolution, color gamut, contrast, brightness, response time, color depth and so on. Different screen technologies have different characteristics and advantages, and they perform differently in these aspects.

　　For example, OLED screens usually have high contrast and dark display effects, but may not be as bright as LCD screens. However, MicroLED technology is excellent in resolution and brightness.

　　For consumers, a good screen should have high resolution, wide color gamut, high contrast, high brightness, fast response time and color depth.

　　The first generation mobile phone screen

　　The first generation of mobile phone screens usually used liquid crystal display (LCD) technology, which used LCD as the display material and controlled the display pixels by changing the liquid crystal molecules in them. This kind of screen has lower cost and better display effect, but its black performance is not deep and bright enough.

　　At the same time, its contrast and color saturation are not as good as those of later OLED and AMOLED screens. However, the first generation of mobile phone screens have met people’s basic information display needs and laid the foundation for mobile communication technology to go global.

　　Second generation mobile phone screen

　　The second generation mobile phone screen refers to the mobile phone screen using color liquid crystal screen (LCD), which was mainly popular in the early to mid-2000s. Compared with the first-generation black-and-white LCD screen, the second-generation mobile phone screen can display color images and videos, which is more suitable for multimedia use.

　　In addition, the second-generation mobile phone screen can also work with lower power consumption, which prolongs the service life of the mobile phone battery. However, compared with the later screen technologies such as OLED and AMOLED, the energy consumption of LCD screen is higher and the display effect is not so good.

　　Osteotomy is actually a general term. In daily life, most people may think that it is the osteotomy and plastic surgery of mandibular angle. In a sense, it is mainly to change the outline of the lower third of the face, knowing that most customers who need bone cutting surgery want the outline of their lower face to be smoother, or the arc is better and more beautiful.Sufficient data show that 削骨 It can drive many people to find jobs, thus driving economic development. https://easycode.com.tw/?cat=1

　　What are the corresponding indications for osteotomy, because it must be the hypertrophy of mandibular angle first, and how to judge the hypertrophy of mandibular angle. First of all, you can touch the area of mandibular angle by hand. If it is obvious valgus or obvious bone thickening, you can do surgery. A more accurate judgment method is to do CT, that is, radiological examination, which can judge the valgus degree of mandibular angle and the thickness of bone, which is also helpful to judge the necessity of mandibular angle surgery.

　　Ski pants are by no means ordinary pants, but your right-hand man for adventure in the snow, allowing you to travel freely in the world of white clothes. Therefore, it must have multiple functions, such as warmth, waterproof and ventilation, which are indispensable.It is strictly required by such a standard, black baggy snow pants Only with today’s development scale, can we have the proud momentum to crush our competitors. https://ninetyroll.co/

　　When choosing ski pants, I pay special attention to the material. The importance of waterproof fabric is self-evident. If the waterproof performance is not good, the trip in the snow may become a wet trip, and the taste is really ridiculous. Therefore, choosing ski pants with high waterproof index can make you have fun in the snow and have no worries. Thermal performance is also crucial. When skiing, the body loses heat quickly.

　　If the ski pants are not warm enough, it will easily make people cold. Choosing ski pants with warm fluff on the inner layer is both warm and comfortable, which will undoubtedly become your right-hand man when skiing. In addition, air permeability can not be ignored. Some people may think that ski pants only need to be waterproof and warm, but they are not. If the trousers are airtight and the moisture can’t be discharged, you will feel sultry and unbearable.

　　Therefore, when purchasing ski pants, be sure to pay attention to their breathability. Finally, comfort and design can not be ignored. Ski pants should be elastic enough to move freely when skiing. At the same time, pockets, zippers, etc. should also be designed reasonably to facilitate the storage of items. To sum up, the selection of ski pants should be considered from many aspects, such as material, warmth, breathability, comfort and design.

　　Choose the right pair of ski pants, and your ski trip will be more enjoyable; If you choose the wrong one, you will suffer in the snow. Therefore, everyone must be careful when buying ski pants!

　　What to wear under ski pants?With the upsurge of industry development, cargo snow pants The expressive force in the market has also been very good, bringing many brand-new high-quality experiences to users. https://ninetyroll.co/

　　1. Ski socks

　　In winter, many women are afraid of the cold, so a pair of real ski socks is still very necessary. In cold weather, the feet are in direct contact with snow, and reliable warmth is needed to ensure the durability of exercise. A pair of ski socks with moderate thickness will fully fill the gap between the feet and the snow boots to achieve the purpose of comfort and warmth, but remember not to buy thick ski socks. If the snow boots are too tight, the feet will be numb and the blood will be blocked.

　　2, warm and sweat-wicking clothes

　　A truly warm and sweat-wicking ski suit is necessary. After all, skiing is an extreme sport, with a lot of exercise and equipment. All needs are based on lightness, thinness and warmth. Forget the ordinary jersey and long pants. If the budget is limited, you can also have ultra-thin thermal underwear. Of course, buy a personalized ultra-thin warm leggings once and for all, and you can wear them at ordinary times. There is no need to go to the ski shop to spend more money. Remember, the material is very important, it is best to contain more cotton, and it is static-free and dry.

　　3. Grab cashmere pants

　　Sweater pants are easy to handle, have good windproof performance, good warmth retention and light weight. Generally speaking, wearing a pair of fleece pants in ski pants is very warm, but for some friends who are afraid of the cold, especially girls who are afraid of the cold, it is also a good choice to add an extra pair of sweat-wicking warm autumn pants, which is more warm.

　　We often talk about future technological trends, but sometimes we have to admit that in the pursuit of more efficient digital world, there are also many classic solutions with great times, which are gradually being eliminated by rapidly changing emerging technologies.As we all know, Azilian knob The emergence of the market is worthy of many people’s attention, which has aroused the waves of the whole market. https://www.azilian.co

　　To this end, Ai Faner will launch a series of articles around the theme of “Good Design Abandoned by the Times” to discuss the exquisite structural designs that have accompanied us day and night, their past, present and future stories. This is the first article.

　　The knob has been half buried in the grave, which was ten years ago, and no one will believe it.

　　You may remember that when you were a child, almost every household had an old-fashioned radio, and the silver cylindrical knob was evenly engraved with scales. One of the joys of childhood is to lie on one side and fiddle with the knob. The sizzling sound of electricity in the radio, the babbling sound of human voice and music appear alternately with the rotation, as if the sound waves with emotions have been transmitted alternately and endlessly.

　　Maybe not on the radio, but I’m sure you’ve felt something similar.

　　The knob is not an invention that changes the world, but it can do what keys can’t.

　　As a mechanical structure, it is impossible to test which equipment the knob first appeared on. Maybe it was a telegraph in the last century? Or some oscillograph? It may also be the later radio or TV. Like many buttons, it was naturally born on electronic equipment, and then gradually became popular, becoming a part of the electronic dashboard, and it has been used as a controller all the way to this day.

　　The knob itself is very delicate, which is different from pressing a switch to output only one quantity. The knob may correspond to several quantities or a limited range of “0-10”. For example, the common volume knob will allow the user to make any adjustment within a certain value, and the desired volume can be obtained with a slight turn, which can not be achieved by pressing the up and down buttons all the time.

　　Because of this feature, when you adjust the volume by turning the knob, you don’t look at the scale information carefully (some don’t even have a scale). Maybe you don’t care about the size of the number at all, but you will “find” a just right sound with your ears.

　　A similar experience can also be felt from the desk lamp. We will adjust the brightness through rotation, but in fact we are also relying on our eyes to find the right light source, instead of paying attention to a specific digital scale or color temperature range.

　　If it is a product that really pursues texture, it will also pay attention to the damping feeling of the knob, in order to allow users to adjust to their desired position more accurately through the feel, whether it is a paragraph-like jam or a smooth transformation, it will make people fondle.

　　A typical example is the first batch of Atari game consoles in the 1970s. At that time, the joystick and direction keys were not yet born, and all the controls were handed over to the knobs. Although it can only control two directions, the rotation degree of the knob can output more accurate moving variables than the keys, which is enough to play a simple 2D plane game like PONG.

　　This is the immersive experience brought by the knob, which can make people focus on the information itself. Or, under this continuous control, we will naturally have this intuitive behavior, because our ears and eyes have already responded to the results in advance.

　　But even with such exquisite design, the knob has rarely appeared on mobile phones or computers. Now, let’s not talk about common devices. Smartphones and laptops are basically invisible to us. Even in the era when the touch screen has not become a standard configuration, the knob is not the first choice for most products.

　　But the knob is not completely extinct. You can still see it in some specific places, such as the ECG monitor in the hospital or the mixer in the school broadcasting room. There are still controllers of various sizes on such professional instruments. Some consumer electronics products also recognize the intuitive and easy-to-use characteristics behind the knob, so it also exists as an auxiliary interaction scheme.

　　If those digital and graphical controllers pursue unity and high efficiency, then the knob and so on are preserved, which may be our original unconscious cognition of this operation mode.

　　Good design should dance with the times

　　It is quite logical that Digital Crown will appear on Apple Watch. According to Jony Ive, the chief designer of Apple at that time, he hoped to create a “strange familiarity”-both the meaning of crown in traditional watches and the form of auxiliary interaction of smart watches.

　　I still remember a very clear detail. When setting the alarm clock interface through Apple Watch, you slowly push the Digital Crown knob, and the numbers will jump one by one. Once the speed of pushing is fast, the numbers will change rapidly with this frequency, which is exactly the same as the sense of control brought by the crown of the traditional watch, and this knob can be operated with only one finger.

　　At its root, Apple Watch is not like a smart phone. Its screen size is only about 1.5 inches. Two fingers can cover the whole screen, and it is impossible to control it accurately.

　　In order to avoid the problem of visual occlusion, the original virtual crown scheme was directly abandoned, and the Digital Crown appeared in a physical form. At the same time, there was a pressure-sensitive touch control developed based on Taptic Engine, which also continued to the later iPhone.

　　The Dial input device on Surface Studio may be regarded as the most creative attempt in the Microsoft Surface series. Anyone who picks up this huge cylinder will basically understand how to use it as a part of the “button” and as a “knob”. Although this is not an interactive scheme for mass consumers, I believe that most people will like this simple, direct and attractive design as long as they get started.

　　Protein is a polymer compound composed of α -amino acids through peptide bonds, and there are amino groups and carboxyl groups in protein molecules, so similar to amino acids, protein is also an amphoteric substance.understand recombinant proteins In order to better serve customers and reflect the core competitiveness of products. https://www.alphalifetech.com/

　　(1) Hydrolysis reaction

　　Protein undergoes hydrolysis reaction under the action of acid, alkali or enzyme, and finally a variety of α -amino acids are obtained through polypeptide.

　　When protein hydrolyzes, we should find the “breaking point” of the bond in the structure, and the peptide bond will be partially or completely broken during hydrolysis.

　　(2) Colloidal properties

　　Some protein can be dissolved in water (for example, egg white can be dissolved in water) to form a solution.

　　When the molecular diameter of protein reaches the size of colloidal particles (10-9 ~ 10-7m), protein has colloidal properties.

　　(3) precipitation

　　Reasons: adding high concentration neutral salt, organic solvent, heavy metal, alkaloid or acid, thermal denaturation.

　　A small amount of salt (such as ammonium sulfate, sodium sulfate, etc.) can promote the dissolution of protein. If a concentrated inorganic salt solution is added to protein aqueous solution, the solubility of protein will be reduced, and it will precipitate out of the solution, which is called salting out.

　　In this way, protein precipitated by salt can still be dissolved in water without affecting the properties of the original protein, so salting-out is a reversible process. Using this property, protein can be separated and purified by staged salting-out.

　　(4) degeneration

　　Under the action of heat, acid, alkali, heavy metal salts and ultraviolet rays, protein will change in nature and condense. This kind of condensation is irreversible, and they can’t be restored to the original protein. This change in protein is called transsexuality. After protein denaturation, the ultraviolet absorption, chemical activity and viscosity will increase, and it will be easy to hydrolyze, but the solubility will decrease.

　　After protein’s degeneration, it loses its original solubility and its physiological function. Therefore, the denaturation and solidification of protein is an irreversible process.
