The development history of LCD screens

The development history of LCD screens

The development of liquid crystal displays (LCDs) is a legend from the laboratory to global popularity. In the early 20th century, Austrian botanist Friedrich Renitzer first discovered the liquid crystal phenomenon, laying the foundation for LCD technology. In 1968, RCA Corporation of the United States demonstrated the first prototype of liquid crystal display, opening up the commercial exploration of LCD technology.

In the 1970s, TN (twisted nematic) liquid crystal display technology made a breakthrough. TN-LCD screens began to be used in portable devices such as electronic watches and calculators due to their fast response speed and low cost. Subsequently, STN (super twisted nematic) technology came out in the 1980s, which improved the contrast and viewing angle and promoted the application of LCD screens in laptops.


In the 1990s, TFT (thin film transistor) technology gradually matured. TFT-LCD screens became the mainstream display technology with their high resolution, high contrast and fast response time, and were widely used in desktop computer monitors, laptops and TVs. At the same time, IPS (plane switching) technology and VA (vertical alignment) technology have made progress in color performance and contrast, respectively, further improving the display effect of LCD screens.

At the beginning of the 21st century, LED backlight technology replaced the traditional CCFL backlight, significantly improving the brightness and contrast of the screen while reducing power consumption. In 2007, Apple launched the iPhone with multi-touch function, which opened up the widespread application of multi-touch technology on LCD screens, bringing users a more convenient and intuitive operation experience.

In recent years, LCD technology has been continuously innovating, and the characteristics of high resolution, high contrast, and wide color gamut have been continuously improved. Mini-LED backlight technology further improves contrast and dynamic range through fine regional dimming. At the same time, LCD screens are also developing towards flexibility, integration and environmental protection, bringing more possibilities for future display technology.

From the initial monochrome display to today's smart touch, the development of LCD screens has not only witnessed the great progress of display technology, but also profoundly affected people's lives and working methods.

  Advantages of AUO, Innolux and Samsung Industrial LCD Screens 1. AUO (1) Wide viewing angle: Most of them adopt advanced IPS technology to ensure that they can still maintain high-quality display effects under different angles and lighting conditions, provide a wide-angle visual experience, and are suitable for a variety of industrial control scenarios, so that operators can view the operating status and data information of the equipment from different angles. (2) High resolution and brightness:   Provide a variety of resolution options, some products have a resolution of up to 3840 (RGB) × 2160 (UHD), which can present delicate and clear images and texts. At the same time, through advanced backlight technology and color management technology, it presents high-brightness and high-saturation pictures, accurate color reproduction, rich details, and can meet the requirements of industrial control equipment for high-definition display and color accuracy. (3) Strong stability: ...
