DISPLAY PANEL - A simplified explanation of the abstract

This abstract first appeared for US patent application 18152438 titled 'DISPLAY PANEL

Simplified Explanation

The patent application describes a display panel that includes a base substrate and multiple subpixels, each containing a light emitting element and a pixel driving circuit. The pixel driving circuit includes a third transistor and a storage capacitor with two capacitor electrodes.

  • The display panel includes a base substrate and multiple subpixels.
  • Each subpixel has a light emitting element and a pixel driving circuit.
  • The pixel driving circuit includes a third transistor and a storage capacitor.
  • The storage capacitor has a first capacitor electrode in a first conductive layer and a second capacitor electrode in a second conductor layer.
  • The second capacitor electrode has an extension that extends away from the main body of the electrode.
  • The extension of the second capacitor electrode overlaps with the active layer of the third transistor when projected onto the base substrate.

Potential applications of this technology:

  • Display panels for electronic devices such as smartphones, tablets, and televisions.
  • High-resolution displays for virtual reality or augmented reality devices.
  • Automotive displays for infotainment systems or instrument clusters.

Problems solved by this technology:

  • Efficient utilization of space within the display panel.
  • Improved performance and reliability of the pixel driving circuit.
  • Enhanced image quality and color accuracy.

Benefits of this technology:

  • Compact design allows for thinner and lighter display panels.
  • Improved energy efficiency and longer battery life for portable devices.
  • Higher pixel density and sharper image quality.
  • Reduced manufacturing costs due to simplified circuitry.


Original Abstract Submitted

A display panel is provided. The display panel includes a base substrate, a plurality of subpixels. A respective subpixel includes a respective light emitting element and a respective pixel driving circuit. The respective pixel driving circuit includes a third transistor; and a storage capacitor including a first capacitor electrode in a first conductive layer and a second capacitor electrode in a second conductor layer. The second conductive layer is on a side of the first conductive layer away from the base substrate. The second capacitor electrode includes an extension extending away from an electrode main body of the second capacitor electrode. An orthographic projection of the extension on the base substrate at least partially overlaps with an orthographic projection of an active layer of the third transistor of the respective pixel driving circuit on the base substrate.
