Brief introduction to color LCD
A Color Liquid Crystal Display generally uses a TFT (Thin Film Transistor) thin film transistor liquid crystal display. The principle is: depositing a layer of silicon on a glass substrate, forming a transistor array by a process such as printing lithography, each pixel is provided with a semiconductor switch, and processing thereof The process is similar to large scale integrated circuits. Then the liquid crystal is poured between the two pieces of glass. Since each pixel can be directly controlled by the point pulse, each node is relatively independent and can be continuously controlled. This design not only improves the response speed of the display screen. At the same time, the display gray scale can be precisely controlled, so the color of the TFT liquid crystal is more realistic, which is called true color. TFT is divided into polysilicon, amorphous silicon and monocrystalline silicon. In March 2004, Samsung released a liquid crystal display device for mobile phones, called UFB (Ultra Fine & Bright) LCD, which has ultra-thin, high brightness. specialty.
Color LCD Screens Compared with LCD monitors, color LCD screens have advantages in terms of brightness, power consumption, viewing angle and refresh rate. The power consumption ratio of LED to LCD is about 10:1, and the higher refresh rate enables LEDs to perform better in video, providing a viewing angle of up to 160° and displaying various text, digital, and color images. And animation information, you can also play TV, video, VCD, DVD and other color video signals, multiple screens can also be broadcast online. The single element of the organic LED display has a reaction speed of 1000 times that of the LCD screen. It can also be taken under strong light and is suitable for low temperatures of minus 40 degrees. LED technology can be used to produce displays that are thinner, brighter, and clearer than LCDs, and have broad application prospects.
