With the improvement of our living standards, there are more and more liquid crystal display products. Simple display technology can no longer meet people's requirements. TFT liquid crystal display screens have been widely used in various industries. So, what is the principle of the TFT liquid crystal display screen, and what are its advantages?
The TFT liquid crystal display screen is composed of two glass substrates, a liquid crystal layer, polarizers, a backlight source, etc. There is a thin-film transistor behind each pixel to control its on-off voltage. When light passes through the upper polarizer, it becomes linearly polarized light, and then passes through the liquid crystal layer. The light undergoes rotation and refraction, thus changing its vibration direction. When the light passes through the lower polarizer, only the light with the same vibration direction as it can pass through, forming bright or dark pixels.
1. The TFT display screen has a good display effect. From a display within the range of 1 to 40 inches to a large projection plane, it is a full-size display terminal. The image quality ranges from simple monochrome character graphics to high resolution, high color fidelity, and high brightness.
2. The TFT display screen has a wide range of applications.
The application of the TFT display screen is very extensive, covering industries such as industry, transportation, medical care, smart home, power, and aviation. There must be reasons behind its wide use. Complete size options, a variety of interface types, and simple development are all important reasons for terminals to choose the TFT display screen.
3. Thin, light, and compact
The TFT liquid crystal display screen achieves the display purpose by controlling the state of the liquid crystal molecules through the electrodes on the display screen. Therefore, even if the screen size is increased, its volume will not increase accordingly. Moreover, it is much lighter in weight than traditional displays with the same display area, making it convenient to carry.
Graphic LED Display is commonly used in various billboards, neon lights, logos and video walls. Compared with segmented digital LED displays, they can provide richer details and clarity for more complex information. It consists of multiple LED (light-emitting diode) pixels arranged in a matrix, and each pixel usually contains three sub-pixels: red (R), green (G), and blue (B). By adjusting the brightness of different color LEDs, various colors can be mixed.
