OLED (organic light-emitting diode) displays have revolutionized the display industry thanks to their excellent performance, flexible design, and energy efficiency. Whether you are looking for components for consumer electronics or researching the latest display technologies, it is important to understand the structure and characteristics of OLED displays.
What are OLED displays?
An OLED (organic light-emitting diode) display is a flat panel display technology that conducts electrical current through organic compounds to create light. Unlike traditional LCD displays, OLED displays do not require a backlight, resulting in deeper blacks, thinner panels, and greater contrast.
The structure of an OLED display
An OLED display consists of several thin layers, each of which plays an important role in light generation and display function:
- Substrate: the base of the display, usually made of glass or flexible plastic.
- Anode: conducts electricity and removes electrons from the organic layer.
- Organic layer:
- Conductive layer: transfers the “holes” created by the anode.
- Light-emitting layer: emits light when the electrons and holes are connected.
- Cathode: pumps electrons into the organic layer.
- Cover layer: protects the organic material from oxygen and moisture.
This simple design makes OLED displays suitable for use in flexible and curved displays as well as in transparent panels.
