Block Diagram
What is OLED?
OLED displays are a new-generation technology utilizing organic compounds with self-emissive characteristics. OLED displays produce higher contrast images, have a wider viewing angle, faster response, and are thinner and more lightweight compared to conventional displays.
Working Principle of OLED
OLED modules have a simple structure with an organic light emitting layer between anodes and cathodes. When a direct current is applied to the device, anodes inject holes with positive charges and cathodes inject electrons with negative charges into the light emitting layer. Then, the organic molecules emit light when the positive hole and the negative electron couple and generate energy in the organic light emitting layer. Because most of the organic materials are insulators and do not easily conduct current, the organic light emitting layers need to be very thin (approximately 0.1µm).
Device Structure of OLED
The typical device structure of OLED is a laminated anode (transparent electrode), a hole injection layer, a hole transport layer, an emitting layer, an electron transport layer, an electron injection layer, and a cathode (metal electrode) on the glass substrate. Each layer is stacked on the glass substrate using vacuum deposition technology. Because organic materials are affected by oxygen and moisture, OLED panels are encapsulated by sealing materials such as metal or glass after being produced into layers on the glass substrate.
