DISPLAY DEVICE AND METHOD FOR MANUFACTURING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18127801 titled 'DISPLAY DEVICE AND METHOD FOR MANUFACTURING THE SAME
Simplified Explanation
The abstract describes a display device with pixel electrodes that have a central part and a peripheral part. A pixel defining layer overlaps the peripheral part and defines a pixel opening exposing the central part. The common electrode is divided into two parts, with the first part on the central part and the second part on the pixel defining layer. The first part is disconnected from the second part along an undercut portion.
- The display device has pixel electrodes with a central and peripheral part.
- The pixel defining layer overlaps the peripheral part and exposes the central part through a pixel opening.
- The common electrode is divided into two parts, one on the central part and the other on the pixel defining layer.
- The first part of the common electrode is disconnected from the second part along an undercut portion.
Potential applications of this technology:
- Display devices such as televisions, monitors, and smartphones.
- Virtual reality and augmented reality headsets.
- Automotive displays and infotainment systems.
Problems solved by this technology:
- Provides a simplified structure for display devices.
- Allows for better control of light emission in each pixel.
- Reduces the risk of electrical short circuits.
Benefits of this technology:
- Improved image quality and color accuracy.
- Enhanced durability and reliability of display devices.
- Cost-effective manufacturing process.
Original Abstract Submitted
A display device includes a plurality of pixel electrodes spaced apart from each other, in which each pixel electrode includes a central part and a peripheral part surrounding the central part, a pixel defining layer disposed on the plurality of pixel electrodes and including an overlap part overlapping the peripheral part when viewed in a plan view, and a lateral side to define a pixel opening exposing the central part, in which a portion of the overlap part has an undercut, a light emitting material disposed on the central part exposed through the pixel opening, and a common electrode including a first part disposed on the light emitting material on the central part and a second part disposed on the pixel defining layer, in which the first part is disconnected from the second part along the undercut portion.
