The Production of TFT LCD Display

The color display industry covers a variety of technology types and product applications, mainly including color LCD screen and LED display two categories. Because of their high resolution, high brightness, high contrast and other characteristics, these displays are widely used in many fields, including but not limited to television, computers, advertising and so on.

‌Color LCD screen (TFT) ‌ :

The color LCD screen, referred to as TFT, uses thin film transistor technology, and each pixel is driven by the thin film transistor integrated in the pixel, which realizes the display effect of high speed, high brightness and high contrast.

TFT screen is not only widely used in laptops and desktops, but also the screen technology commonly used in high-end color screen mobile phones, providing 65536 colors and 260,000 colors, or even 16 million color display effects.

‌LED display ‌ :

LED display is classified according to the use environment and color, including indoor, outdoor and semi-outdoor use environment, as well as monochrome, double primary color, three primary color (full color) color classification.

Indoor screen is suitable for use in indoor environment, with moderate brightness, large viewing Angle, color mixing distance and other characteristics; The outdoor screen needs to have high brightness, good wind and rain resistance and lightning protection ability to adapt to the extreme outdoor environment.

The full-color LED display is composed of red, green and blue LED lights, capable of displaying white balance and 16,777,216 colors, and is widely used in advertising and indoor and outdoor displays.

In addition, the color display industry also involves a number of technical indicators such as pixel spacing, gray level, brightness, and viewing Angle of the display screen, which directly affect the display effect and the use of environmental adaptability. For example, the smaller the pixel spacing, the higher the image resolution, the clearer the image; Brightness determines the visibility of the display under different lighting conditions; The viewing Angle is related to the sharpness and color accuracy of the image when the viewer views the display from different angles.

To sum up, the development of color display industry is not only reflected in the continuous innovation and progress of technology, but also in the wide application of products and the continuous optimization of technical indicators to meet the needs of different fields and different use environments.
