PIXEL DRIVING CIRCUIT AND METHOD OF DRIVING THE SAME, DISPLAY SUBSTRATE AND DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17626474 titled 'PIXEL DRIVING CIRCUIT AND METHOD OF DRIVING THE SAME, DISPLAY SUBSTRATE AND DISPLAY DEVICE

Simplified Explanation

The abstract describes a pixel driving circuit that includes various sub-circuits for compensation, reset, and light emitting control.

  • The compensation sub-circuit is connected to different control terminals and a second terminal of the driving sub-circuit.
  • The first coupling sub-circuit is connected to the control terminal of the driving sub-circuit.
  • The second coupling sub-circuit is connected to the second terminal of the first coupling sub-circuit.
  • The first reset sub-circuit is connected to the second control terminal, the control terminal of the driving sub-circuit, and an initialization signal output terminal.
  • The second reset sub-circuit is connected to the third control terminal, the second terminal of the first coupling sub-circuit, and the first level signal output terminal.
  • The first light emitting control sub-circuit is connected to the light emitting control terminal, the second terminal of the second coupling sub-circuit, and a reference signal output terminal.

Potential applications of this technology:

  • Display panels in electronic devices such as smartphones, tablets, and televisions.
  • LED screens for advertising displays, stadium scoreboards, and outdoor signage.

Problems solved by this technology:

  • Provides a pixel driving circuit that can compensate for various factors affecting the display quality.
  • Offers reset sub-circuits for initializing the driving sub-circuit and adjusting the signal levels.
  • Enables precise control of light emission in the pixel.
