PIXEL CIRCUIT, PIXEL CIRCUIT DRIVING METHOD AND DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18145655 titled 'PIXEL CIRCUIT, PIXEL CIRCUIT DRIVING METHOD AND DISPLAY DEVICE

Simplified Explanation

The patent application describes a pixel circuit that includes various components for controlling the operation of a light-emitting element.

  • The circuit includes a light-emitting element, a capacitor structure, a driving transistor, and four switching elements.
  • The first switching element connects a data line to a terminal of the capacitor structure when a first scan signal is received.
  • The second switching element connects the driving transistor to its control terminal and the capacitor structure's second terminal when a second scan signal is received.
  • The third switching element connects the driving transistor's second terminal to the light-emitting element's first terminal when a third scan signal is received.
  • The fourth switching element connects a power signal terminal to the driving transistor's first terminal when a fourth scan signal is received.


Original Abstract Submitted

A pixel circuit includes a light-emitting element, a capacitor structure, a driving transistor, and first to fourth switching elements. The first switching element connects a data line for providing a data signal to a first terminal of the capacitor structure in response to a first scan signal. The second switching element connects a first terminal of the driving transistor to a control terminal of the driving transistor and a second terminal of the capacitor structure respectively in response to a second scan signal. The third switching element connects a second terminal of the driving transistor to a first terminal of the light-emitting element in response to a third scan signal. The fourth switching element connects a first power signal terminal to the first terminal of the driving transistor in response to a fourth scan signal.
