DISPLAY SUBSTRATE AND DISPLAY APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17795950 titled 'DISPLAY SUBSTRATE AND DISPLAY APPARATUS

Simplified Explanation

The patent application describes a display substrate that includes a base substrate with a display area and a peripheral area. The display area contains an array of pixel units, each consisting of a pixel driver circuit and a light-emitting device. The light-emitting device has a cathode, an anode, and a light-emitting layer between them. The peripheral area includes a cathode line that surrounds the display area and is connected to the cathode at multiple positions. Additionally, the cathode line includes a first cathode sub-line in the same layer as the anode.

  • The display substrate has a base substrate with a display area and a peripheral area.
  • The display area contains an array of pixel units with pixel driver circuits and light-emitting devices.
  • The light-emitting devices have a cathode, an anode, and a light-emitting layer.
  • The peripheral area includes a cathode line that surrounds the display area and connects to the cathode at multiple positions.
  • The cathode line includes a first cathode sub-line in the same layer as the anode.

Potential Applications

This technology can be applied in various display devices, such as:

  • OLED (Organic Light-Emitting Diode) displays
  • LED (Light-Emitting Diode) displays
  • LCD (Liquid Crystal Display) screens

Problems Solved

The patent application addresses the following problems:

  • Efficiently connecting the cathode of the light-emitting devices in a display substrate.
  • Providing a cathode line that surrounds the display area and connects to the cathode at multiple positions.
  • Simplifying the structure and manufacturing process of the display substrate.

Benefits

The benefits of this technology include:

  • Improved electrical connectivity between the cathode line and the light-emitting devices.
  • Enhanced structural integrity of the display substrate.
  • Simplified manufacturing process, leading to cost reduction and increased production efficiency.


Original Abstract Submitted

A display substrate is provided. The display substrate includes: a base substrate including a display area and a peripheral area located on at least a first side of the display area; a plurality of pixel units arranged in an array along a first direction and a second direction in the display area of the base substrate, where the pixel units include a pixel driver circuit and a light-emitting device electrically connected to the pixel driver circuit, and the light-emitting device includes a cathode, an anode, and a light-emitting layer disposed between the cathode and the anode; and a cathode line located in the peripheral area and electrically connected to the cathode. The cathode line substantially surrounds the display area and is electrically connected to the cathode line at a plurality of positions. The cathode line includes a first cathode sub-line located in the same layer as the anode.
