Take LCD as an example
Take LCD as an example. It mainly consists of the following parts... 1. Driver board (also called motherboard): it is mainly used to receive and process analog (VGA) or digital (DVI) video signals sent in from outside, and send out signals through screen cable to control the normal operation of LCD (panel). The driver board contains MCU unit, which is the detection control center and brain of LCD.. 2. Power supply board: it is used to convert 90 ~ 24ov AC voltage into 12V, 5V, 3V DC power supply for display.. 3. Backlight board (also called high voltage board): it is used to convert the 12V DC voltage output from the main board or power board into the 1500 ~ 1800V high voltage AC required by the panel to light up the backlight of the panel. Power board and backlight board sometimes do together, that is, the so-called power backlight two in one board.. 4. LCD: LCD module, which is the core component of LCD, contains LCD board and driving circuit. Among them, the LCD is the most critical part of the LCD, which plays a decisive role in the performance and price of the LCD.. Electron tube display: circuit board, semiconductor triode, integrated circuit, picture tube, line, field scanning, line output transformer [high voltage package] deflection, switching power supply,... Countless, at least a hundred or even thousands of parts and circuits!. Liquid crystal display (LCD): different from the display principle of picture tube, the display principle is the same as above..
