This fundamental difference in design allows for superior picture quality and a more immersive viewing experience.
How Does OLED Work?
To better understand OLED technology, it’s essential to break down its components and functioning.
Structure of OLED Panels
An OLED display consists of several layers, each playing a key role in creating images:
Substrate: This is the base layer that supports the OLED structure. It is usually made from glass or flexible plastic.
Anode: A transparent electrode that allows the passage of current and helps to move electrons within the organic layers.
Organic Layers: These are the layers responsible for light emission. There are typically two layers:
- Emissive Layer: This layer contains organic molecules that emit light when excited by electricity.
Conductive Layer: This layer helps to transport holes (the absence of electrons) to the emissive layer.
Cathode: The layer that injects electrons into the conductive layer, allowing the OLED to function.
The Light Emission Process
When electricity is applied to the cathode, electrons are injected into the conductive layer. These electrons move toward the emissive layer, where they recombine with holes (missing electrons) to create excitons. As excitons decay, they release energy in the form of light. This process is what gives OLEDs their characteristic brightness and color vibrancy.
