DISPLAY PANEL - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240032346 titled 'DISPLAY PANEL

Simplified Explanation

The abstract describes a display panel that includes a first display area with a display substrate and an optical layer. The display substrate has a pixel defining layer and a cathode layer, with the pixel defining layer having pixel openings and supporting portions between them. The cathode layer on the pixel openings is thicker than on the supporting portions. The optical layer has first optical structures corresponding to the supporting portions, with each structure having a first surface close to the cathode layer, a second surface opposite to the first surface, and a side surface that is a total reflective surface.

  • The display panel includes a display substrate and an optical layer.
  • The display substrate has pixel openings and supporting portions.
  • The cathode layer on the pixel openings is thicker than on the supporting portions.
  • The optical layer has first optical structures corresponding to the supporting portions.
  • Each first optical structure has a first surface, a second surface, and a total reflective side surface.

Potential Applications:

  • This display panel technology can be used in various electronic devices such as smartphones, tablets, and televisions.
  • It can enhance the visual quality and brightness of the display, providing a better viewing experience for users.

Problems Solved:

  • The thicker cathode layer on the pixel openings helps to improve the electron emission efficiency, resulting in better pixel performance and image quality.
  • The first optical structures with total reflective side surfaces help to reduce light leakage and enhance the overall display contrast.

Benefits:

  • Improved visual quality and brightness of the display.
  • Enhanced contrast and reduced light leakage.
  • Better electron emission efficiency and pixel performance.



Original Abstract Submitted

a display panel includes a first display area. the first display area includes a display substrate and an optical layer. the display substrate includes a pixel defining layer and a cathode layer disposed on the pixel defining layer. the pixel defining layer includes a plurality of pixel openings and a plurality of supporting portions each disposed between two adjacent pixel openings. a thickness of a part of the cathode layer on each of the pixel opening is greater than a thickness of a part of the cathode layer on each of the supporting portions. the optical layer is disposed on the cathode layer and includes a plurality of first optical structures corresponding to the supporting portions. each of the first optical structures includes a first surface close to the cathode layer, a second surface opposite to the first surface, and a side surface that is a total reflective surface.
