Flat panel display is a generic term for video display devices with a thin, flat screen, and has become popular as a video display device to replace the conventional CRT (cathode-ray tube). Flat panel displays include liquid crystal displays (LCDs), plasma displays, organic light emitting diode (OLED) displays, quantum dot LED displays (QLEDs), and electronic paper. The FPD is far thinner than CRT and enables higher resolution on large screens.
It is used in many applications, including smartphones, tablets, game consoles, machine control panels, and digital signage, in addition to televisions and computer monitors.
In the process of the FPD manufacturing, circuit design, glass printed circuit board (PCB) processing, and lighting inspection are taken.
As for OLED panels, a film of a specific organic compound is formed on the surface of the display material, and an electric current is passed through it to emit light, showing images.
"Vapor deposition" technology is applied to create the organic compound film.
In vacuum deposition methods, resistive heating using a heater requires a DC power supply to control the heater.
