PIXEL CIRCUIT - A simplified explanation of the abstract

This abstract first appeared for US patent application 17622771 titled 'PIXEL CIRCUIT

Simplified Explanation

The abstract describes a pixel circuit that includes a switching circuit, a storage circuit, a driving circuit, and a pull-down circuit. The switching circuit provides power signals to the storage circuit based on a gate-driving signal. The storage circuit provides data signals to a first node based on the power signals. The driving circuit writes the voltage signal of the first node into the pixel electrode based on a second gate-driving signal. The circuit structure of this pixel circuit is simplified, using fewer transistors and occupying less area, making it suitable for high-resolution display devices.

Original Abstract Submitted

A pixel circuit including a switching circuit, a storage circuit, a driving circuit, and a pull-down circuit is disclosed. The switching circuit is configured for providing first and second power signals to the storage circuit according to a first gate-driving signal. The storage circuit is configured for providing a corresponding one of first and second data signals to a first node in response to one of the first and second power signals. The driving circuit is configured for writing the voltage signal of the first node into the pixel electrode according to a second gate-driving signal. The circuit structure of the pixel circuit of the present disclosure is relatively simplified. The number of transistors used is less, such that the occupied area is small, thereby facilitating realization of a high-resolution display device.
