DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240023378 titled 'DISPLAY DEVICE
Simplified Explanation
The abstract describes a display device that consists of pixels, each having an emission area and a non-emission area. Each pixel includes a driving voltage line, a via layer, a first electrode, a pixel defining layer, an emission layer, and a second electrode. The via layer covers one side of the driving voltage line, and the pixel defining layer includes openings in both the emission and non-emission areas. The emission layer is disposed in the opening in the emission area, and the second electrode is disposed on top of the emission layer and the pixel defining layer. The second opening and the first via hole partially overlap each other.
- The display device includes pixels with emission and non-emission areas.
- Each pixel has a driving voltage line and a via layer covering one side of the driving voltage line.
- The pixel defining layer includes openings in both the emission and non-emission areas.
- The emission layer is placed in the opening in the emission area.
- The second electrode is disposed on top of the emission layer and the pixel defining layer.
- The second opening and the first via hole partially overlap each other.
Potential applications of this technology:
- This display device can be used in various electronic devices such as smartphones, tablets, and televisions.
- It can be used in augmented reality (AR) and virtual reality (VR) headsets to provide high-quality visual experiences.
- The display device can be used in automotive displays to enhance the driver's visibility and safety.
Problems solved by this technology:
- The display device provides improved image quality and resolution due to the precise placement of the emission layer.
- The overlapping of the second opening and the first via hole helps in reducing the size of the pixel, allowing for higher pixel density and sharper images.
- The via layer covering the driving voltage line helps in preventing electrical interference and improves the overall performance of the display device.
Benefits of this technology:
- The display device offers enhanced visual experiences with high image quality and resolution.
- The smaller pixel size allows for higher pixel density, resulting in sharper and more detailed images.
- The reduction in electrical interference improves the performance and reliability of the display device.
Original Abstract Submitted
a display device includes pixels each including an emission area and a non-emission area. each pixel includes: a driving voltage line; a via layer disposed on the driving voltage line and including a first via hole exposing a first side of the driving voltage line, and a second via hole; a first electrode disposed on the via layer; a pixel defining layer disposed on the first electrode and the via layer and including a first opening formed in the emission area to expose a portion of the first electrode, and a second opening disposed in the non-emission area; an emission layer disposed in the first opening; and a second electrode disposed on the emission layer and the pixel defining layer. the second opening and the first via hole partially overlap each other. the via layer covers a second side of the driving voltage line.
