How To Distinguish Lcd Liquid Crystal Screen And Lcd Backlight

2022-12-10

The LCD liquid crystal screen is not a common LCD backlight, and the LCD display is also called an electronic display or floating characters. By LCD dot matrix and LCD, PC panel, text, image, animation, video and content are displayed through red, blue, white and green LCD on and off. According to different occasions, different supervision, such as general billboards, these flowing calligraphy can be produced according to the needs of flash animation, stored in the display of the memory card, and then displayed by technical methods, and can be changed at any time according to different needs. The various parts are shown in the modular structure of the device. A traditional LCD screen usually consists of a display module, a control system and a power supply system.

The color and luminous efficiency of LCD light Liquid Crystal Display Module emission and production materials and related LCD light bulbs are all blue at the beginning, but later together with phosphors, different light colors are adjusted according to different needs of users, widely used red, green, blue, Yellow 4. Due to the low operating voltage of the LCD, it can actively emit light and have a certain brightness, brightness and voltage adjustment, and it is shock-resistant, anti-vibration, and has a long life (100,000 hours). Therefore, there are no other display methods and LCDs in large-scale display devices. LCD screen matches.

Red and green LCD chips or lamps are made together as pixels to display so-called black and white or monochrome screens and three-color or two-color screens, red, green and blue LCD chips or discharge lamps are used together as a pixel display called three-color screens or Full color screen. If there is only one color, it is called monochrome. The pixel size of the indoor LCD screen is generally 2-16mm, which is often used to make a variety of LCD dies of different colors into one package. The pixel size of the outdoor LCD large screen is mainly 6 mm-31.5, each pixel consists of several monochromatic Liquid Crystal Displays, which means pixel tubes, and two-color pixel tubes are generally composed of two red, one green, three-color pixel tubes, one red, one green, and blue to form an ordinary product.

LCD screen People's life and closer cooperation
Whether to produce a single-color, two-color or three-color screen with the Liquid Crystal Display Module, the image needs to be displayed by adjusting the brightness of each LCD that constitutes the pixel to be able to adjust the fineness of the gray scale. The higher the level, the more delicate the grayscale image is displayed, the richer the color, and the corresponding display control system is more complicated. Generally, for images with 256-level grayscale, the color transition is very soft, while for color images with 16-level grayscale, the boundary line of color transition is very obvious. So, the demand for color LCD display is doing 256-4096 gray.

Through extensive attention and rapid development of Reflecting Liquid Crystal Display, this is inseparable from its own advantages. LCD has extremely broad development prospects, and is developing towards higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability, and full color.
