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.
The FPD manufacturing process involves several key stages, including circuit design, thin-film transistor (TFT) array processing on glass substrates, and lighting inspection.
For OLED panels in particular, a film of a specific organic compound is formed on the substrate. An electric current is then passed through this film, causing it to emit light and display images.
This organic film is created using "vapor deposition" technology. In this process, resistive heating is employed to evaporate the material, and a programmable DC power supply is essential for precise control of the heater.
Matsusada Precision's programmable DC power supplies are widely used in FPD manufacturing equipment for these demanding applications.
