OLED is Short for organic light-emitting diode, a OLED Display Module device that sandwiches carbon-based films between two charged electrodes, one a metallic cathode and one a transparent anode, usually being glass. The organic films consist of a hole-injection layer, a hole-transport layer, an emissive layer and an electron-transport layer. When voltage is applied to the OLED cell, the injected positive and negative charges recombine in the emissive layer and create electro luminescent light. Unlike LCDs, which require backlighting, OLED displays are emissive devices - they emit light rather than modulate transmitted or reflected light.
lcd module displays screen splicing present the main application areas include security, command centers, entertainment industry, company presentations, advertising, media, exhibition center, electricity, education and so on. Advantages of lcd -screen high-resolution, high-brightness, high color saturation, flexible tiled display combinations, environmental health, long life, low maintenance costs, viewing angle, low power consumption, low heat, affordable .
