Summarize the advantages of LED LCD: LED LCD TV has the advantages of power saving, environmental protection, and more realistic colors. (4) Application and new technology of liquid crystal display   (1) Driven by TFT-type Active element

In order to create a better picture structure, the new technology uses a unique TFT-type AcTIve element for driving. Everyone knows that the most important part of an extremely complex LCD screen is liquid crystal, it is the backlight screen that is directly related to the brightness of the liquid crystal display and the color filter that is responsible for producing colors. Each liquid crystal pixel is equipped with AcTIve element for point-to-point control, which makes the display screen very different from the entire CRT display screen. This control mode is better than the previous control method in terms of display accuracy. It is much higher, so the image quality is poor, color bleeding and jitter are very serious on the CRT display, but the picture quality is quite pleasing when viewed on the COG LCD display with the new technology.

(2) Use the color filter manufacturing process to create colorful pictures

Before the main body of the color filter is fabricated, the material that constitutes the main body is dyed, and then it is made by filling it with a film. This process requires very high manufacturing standards. But compared with other ordinary LCD display screens, LCDs manufactured with this type of display have excellent performance in terms of resolution, color characteristics, and service life. This enables LCD to create colorful images in high-resolution environments.

(3) Low-reflection liquid crystal display technology

As we all know, external light has a very large interference to the LCD screen. When the external light is relatively strong, the glass plate on the surface of some LCD screens interferes with its normal display. Therefore, its performance and observability will be greatly reduced when used in some bright public places outdoors. At present, even if the resolution of many LCD displays is high, the reflection technology is not handled well, so it is not practical for applications in actual work. Some pure data alone is actually a biased behavior to guide users. The "low reflection liquid crystal display screen" technology used in the new LCD display is to apply AR coat to the outermost layer of the liquid crystal display. With this layer of paint, the liquid crystal display screen emits The gloss, the light transmittance of the liquid crystal display screen itself, the resolution of the liquid crystal display screen, and the prevention of reflection have all been improved.
