DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240237500 titled 'DISPLAY DEVICE
The display device described in the abstract includes a substrate, a transistor, a pixel electrode, a pixel defining layer, an emission layer, a common electrode, an encapsulation layer, a light extraction pattern, and a reflection control layer.
- The pixel electrode is electrically connected to the transistor.
- The pixel defining layer has a first opening overlapping the pixel electrode.
- The common electrode is on the pixel definition layer and the emission layer.
- The encapsulation layer covers the common electrode.
- The light extraction pattern on the encapsulation layer has a first refractive index.
- The reflection control layer covering the light extraction pattern has a second refractive index different from the first refractive index.
Potential Applications: - This technology can be used in high-resolution displays for electronic devices. - It can enhance the brightness and clarity of screens in smartphones, tablets, and televisions. - The display device can be utilized in virtual reality headsets and augmented reality glasses for immersive experiences.
