LCD (Liquid Crystal Display) liquid crystal display technology is widely used in modern electronic devices with its thin, light and power-saving characteristics. With the development of science and technology, more and more types of LCD screens have emerged, bringing more convenience to our lives. This article will introduce several major types of LCD screens in detail.     1. TN-LCD screen   TN-LCD (Twisted Nematic Liquid Crystal Display) is one of the earliest practical applications of liquid crystal display technology. Compared with other types of LCD screens, TN-LCD screens have lower manufacturing costs and faster response speeds, which are suitable for ordinary display needs. However, due to its shortcomings such as narrow viewing angle, low brightness and poor color accuracy, it has gradually been replaced by other more advanced screens.       2. VA-LCD screen   VA-LCD (Vertical Alignment Liquid Crystal Display) is an improved TN-LCD screen with improved viewing angle and color accuracy. VA-LCD screens use liquid crystal molecules to rotate in the vertical direction to control the transmission of light, thereby improving viewing angle and color. This type of screen has obvious advantages in color performance and contrast, and is suitable for high-demand image display.     3.IPS-LCD screen   IPS-LCD (In-Plane Switching Liquid Crystal Display) is a liquid crystal screen with obvious advantages in color performance, viewing angle and response speed.

TN-LCD, VA-LCD, and IPS-LCD screens are suitable for different application scenarios and meet the needs of different users for color accuracy, viewing angle and response speed. With the advantages of OLED screens and MicroLED screens, we can expect greater breakthroughs and innovations in LCD display technology in the future.

There are many brands of LCD display in the market today, usually we can divide into two main parts, industrial LCD Display and consumer LCD diaplay. First, let's explain the difference between industrial display screens and consumer display screens. Although both are used for display, the requirements of industrial LCD display screens are higher than those of consumer ones. We can understand it from the following aspects.   Stability: The use environment of industrial LCD display screens is much worse than that of consumer display screens such as our mobile phones, computers, and TVs. Industrial LCD display screens are almost powered on 365 days a year. Secondly, depending on the purpose and environment, industrial LCD display screens are required to have different characteristics. Such as higher stability, anti-interference, vibration, impact, and temperature changes. Like our company's popular 90-07018-IH2, 90-10301-BS4, LCD display screens used in car central control, it needs to be used in high temperature and low temperature environments, and must adapt to long-term stable work, which is incomparable to consumer display screens.   Readability in sunlight Good visibility is a major feature of industrial LCD displays. LCD screens used in industry are mostly surrounded by strong light, such as strong sunlight on a sunny day. LCD displays for outdoor operations need to work under direct sunlight for a long time, which requires our displays to be readable in sunlight. There is a model 90-05018-BH1, a 5-inch LCD display used on outdoor beach cars, which is also clearly readable under direct sunlight.     Customizable Consumer LCD displays are all standard, just like when you buy the latest mobile phone of a certain brand, you think the screen is too big and want a smaller one. At this time, you can't ask the manufacturer to customize a model with the same configuration and a small display screen for you, but choose to buy a model that is closest to what you want. Industrial LCD displays are different. If conditions permit, manufacturers can customize them according to customer needs. For example, if you want to develop a full-viewing angle, wide temperature, and touch screen product based on a standard product, we can help you achieve it. Of course, the mold opening fee may be a little higher. This is also one of the reasons why industrial LCD displays are more expensive than consumer LCD displays. Strict material selection (high-quality raw materials) Another advantage of industrial LCD display screens is that we use industrial-grade high-quality raw materials throughout the product, because only LCD display products designed and produced with high-quality components can pass various rigorous tests: anti-static (ESD) and electromagnetic (EMI) interference, aging test, high and low temperature test, etc., so that the whole machine has high and low temperature resistance, anti-interference, and extreme impact. The raw materials used in consumer display products are usually mid-range materials. Before the production of TFT under touch display, there is a very strict incoming material inspection to ensure the quality of raw materials first.   Supply cycle There is also a big difference in the supply cycle between industrial LCD display screens and consumer display screens. For industrial LCD display screens, under the normal supply of materials such as IC and glass, the supply cycle of industrial LCD display screens is relatively long, usually about 10 years. Unless the specified material is completely discontinued, we still have an upgrade plan. It only requires a slight modification of the customer's equipment, or even no modification at all, to be applied. Therefore, customers do not need to worry about the discontinuation of production and supply of industrial LCD display screens leading to equipment scrapping. Consumer displays are different. For example, mobile phones are updated very quickly. I don't know if you have this feeling: you just changed to the latest mobile phone of a certain brand, but before you use it for half a year, the overwhelming new product launch conference has started again. In two or three years, the model you use may have been discontinued. Therefore, the life cycle of consumer displays is much shorter than that of industrial LCD displays.   Price Price is a problem that everyone is very concerned about. Combining the above points, it is not difficult to see that the price of industrial LCD displays is higher than that of consumer displays. You get what you pay for. Industrial LCD displays not only have good configurations, but also have better after-sales service. For example, if you buy a computer, the warranty period is generally between 6 and 12 months, and you also need to purchase an insurance period. If there is a problem after this time, you need to pay a higher repair fee. However, for industrial displays, the warranty period is usually at least 1 year, and the longest is even 3 years. If it is a supplier problem, you can also replace the new display. Therefore, although the price of industrial LCD displays is high, the after-sales service is very good and cost-effective. -In the next article, we will explain to you the criteria for judging the effect of industrial displays      

Wide Viewing Angle Display Technology Wide viewing angle technology introduction MVA wide viewing angle Multi-domain Vertical Alignment, Fujitsu, Chimei, AUO. For MVA (Multi-domain Vertical Alignment) mode LCDs, the long axis of the liquid crystal molecules is not parallel to the screen like the TN mode when not powered, but perpendicular to the screen, and each pixel is composed of multiple vertically oriented liquid crystal molecule domains. When voltage is applied to the liquid crystal, the liquid crystal molecules tilt in different directions. In this way, the screen can be compensated in the corresponding direction when viewed from different angles, which improves the viewing angle.   IPS wide viewing angle In-Plane Switching, Hitachi, LG Philips. Like MVA wide viewing angle technology, IPS (In Plane Switching) mode wide viewing angle technology also focuses on the long axis orientation of liquid crystal molecules. The difference is that the liquid crystal display using IPS wide viewing angle technology allows the observer to only see the short axis of the liquid crystal molecules at any time, so the picture viewed from different angles will not be too different, which perfectly improves the viewing angle of the LCD.   PVA wide viewing angle Patterned Vertical Alignment, Samsung Electronics.   OCB wide viewing angle Optical Compensated Birefringence, Panasonic, Japan.   OCB (Optically Compensated Bend/Optical Compensated Birefringence) wide viewing angle technology uses its cleverly designed liquid crystal molecular arrangement to achieve self-compensation viewing angle, so it is also called self-compensation mode.   Under the compensation of self-compensation and biaxial optical film, OCB mode liquid crystal can achieve a good viewing angle, and the viewing angle uniformity is very good. As shown in the figure, the grayscale reversal phenomenon inherent in the TN mode will not occur in different directions.   FFS wide viewing angle Fringe Field Switching, Hyundai, South Korea, BOE. Just like the relationship between PVA mode and MVA mode, FFS (Fringe Field Switching) should strictly be a branch of IPS mode. The main improvement is the use of transparent electrodes to increase light transmittance. Compared with the already perfect IPS mode, FFS can be said to be "going one step further".     The first generation of FFS technology mainly solves the problem of low light transmittance caused by the inherent low aperture ratio of the IPS mode and reduces power consumption. The second generation of FFS technology (Ultra FFS) improves the FFS color shift phenomenon and shortens the response time. The third generation of FFS technology (Advanced FFS) has significantly improved light transmittance, contrast, brightness, viewing angle, and color difference.   ASV wide viewing angle Advanced Super View, Japan Sharp (CPA). Sharp CPA (Continuous PineWheel Alignment) technology is "continuous flame-like arrangement technology".   Extra view wide viewing angle Japan NEC.   Wide viewing angle technology comparizon    

The meaning of wide-temperature LCD screens A wide-temperature LCD screen refers to an LCD screen that can work normally within a wide temperature range. Compared with standard LCD screens, wide-temperature LCD screens are optimized in design and materials to adapt to more extreme temperature conditions. Generally speaking, wide-temperature LCD screens can work normally in a temperature range of -20°C to 70°C, and some specially designed wide-temperature LCD screens can even start at lower temperatures or maintain stable operation at higher temperatures. So what problems will occur when the LCD screen exceeds the operating temperature range? First, let's take a look at the working principle of the LCD screen. The main material of the LCD screen is liquid crystal molecules. Liquid crystal materials are filled between two parallel substrates. The direction and arrangement of liquid crystal molecules are changed by voltage to achieve the effect of shading and light transmission to display the depth of the picture. Then, a filter layer of RGB primary colors is added between the two substrates. Finally, the final color dynamic picture can be displayed by lighting the backlight. Liquid crystal molecules will definitely be affected by the ambient temperature. When the temperature is too high, the liquid crystal molecules will also heat up, rotate faster, and the color on the screen will become darker. When the temperature is extremely low, the liquid crystal molecules will crystallize, rotate slower, the display color will become lighter, and the dynamic image will also become slower. At the same time, high and low temperature environments will also affect the normal operation of the backlight. Therefore, when the LCD screen exceeds its own operating temperature range, the display image will be distorted and the image cannot be displayed normally. How does the wide temperature LCD screen work normally in the range of -30℃~+85℃? First of all, the wide temperature LCD screen has optimized the liquid crystal material and adopted a more stable VA liquid crystal material, thereby improving the high temperature and low temperature resistance of the LCD screen. Conventional screens generally use TN liquid crystal materials. Secondly, in the main structure of the screen, the wide temperature LCD screen uses a sturdy material that is resistant to high temperature and deformation, ensuring that the screen can display normally without deformation in any temperature environment. Finally, it is also necessary to work hard on the choice of backlight. The wide temperature LCD screen uses a warmer LED backlight, which has better high temperature and low temperature resistance. Compared with ordinary cold cathode fluorescent lamps, it can provide a continuous and stable backlight source for the screen in a wider operating temperature range. Advantages of wide temperature LCD screen 1. Stability: Wide temperature LCD screen can maintain stable working performance in a large temperature range, reducing failures and maintenance costs caused by temperature changes. 2. Reliability: Wide temperature LCD screen is made of special materials and processes, which improves the durability and reliability of the display and extends the service life of the equipment. 3. Applicability: Wide temperature LCD screen is suitable for various industrial environments, including high temperature, low temperature, high humidity, dust and other harsh conditions, and has strong environmental adaptability. 4. Safety: In industrial applications, the safe operation of equipment is crucial. Wide temperature LCD screen can maintain clear display in various environments, which helps operators to accurately read data and alarm information and ensure production safety. Today's LCD screens have been applied to various fields, and different working fields have brought different application environments. Therefore, the working temperature of LCD screens has become an important technical parameter, and many customers will have customized requirements for the working temperature of the screen. Zhongyou Technology has more than ten years of experience in LCD screens, and has very mature and successful experience in customizing modules. Please contact us for any LCD touch screen project.
