DISPLAY PANEL AND DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17769457 titled 'DISPLAY PANEL AND DISPLAY DEVICE

Simplified Explanation

The patent application describes a display panel with a display area consisting of pixel areas and gate driving circuit areas. Each pixel area has a light-emitting sub-area and a circuit sub-area, and the gate driving circuit areas are located between the pixel areas in each row. The panel also includes a gate driving circuit with cascaded shift registers and light-shielding portions that are placed around the transistor groups in the circuit area.

  • The display panel has a display area with pixel areas and gate driving circuit areas.
  • Each pixel area consists of a light-emitting sub-area and a circuit sub-area.
  • The gate driving circuit areas are located between the pixel areas in each row.
  • The gate driving circuit includes cascaded shift registers.
  • Each shift register is made up of transistor groups, with each group having at least one transistor.
  • Light-shielding portions are placed around the transistor groups in the gate driving circuit areas.
  • The light-shielding portions are electrically connected to a power supply signal line.

Potential Applications

  • This display panel technology can be used in various electronic devices such as smartphones, tablets, televisions, and computer monitors.
  • It can enhance the visual quality and performance of these devices by improving the display area and gate driving circuit design.

Problems Solved

  • The design of the display panel addresses the need for efficient and effective pixel and circuit arrangement.
  • The placement of gate driving circuit areas between pixel areas helps optimize the display area and improve overall performance.
  • The use of light-shielding portions around transistor groups helps prevent interference and improve image quality.

Benefits

  • The display panel provides a more compact and efficient design by arranging pixel areas and gate driving circuit areas effectively.
  • The cascaded shift registers in the gate driving circuit enhance the performance and functionality of the display panel.
  • The light-shielding portions help reduce interference and improve the visual quality of the display.

Original Abstract Submitted

A display panel has a display area including a plurality of pixel areas arranged in an array and a plurality of gate driving circuit areas. Each pixel area includes a pixel light-emitting sub-area and a pixel circuit sub-area arranged in a first direction. Pixel areas in each row correspond to at least two gate driving circuit areas each located between two adjacent pixel areas in this row. The display panel includes a gate driving circuit and a plurality of light-shielding portions. The gate driving circuit includes a plurality of shift registers that are cascaded. Each shift register includes a plurality of transistor groups, and each transistor group includes at least one transistor. Each light-shielding portion is located in a gate driving circuit area in which a transistor group is disposed, and is disposed on a periphery of the transistor group, and is electrically connected to a power supply signal line.
