DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18328015 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device with multiple layers including a base layer, circuit layer, electrodes, and various transport layers to create a functional display.
- The display device includes a base layer and a circuit layer on top of it.
- A first electrode is placed on the circuit layer, with a pixel defining film exposing a portion of the electrode.
- An electron injection layer is on the first electrode, followed by an electron transport layer, emission layer, and hole transport region.
- A second electrode is on the hole transport region, completing the display device structure.
