Embodiment Construction

[0050] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0051] In this document, it is understandable that terms such as first, second and third are used to describe various elements, components, regions, layers and / or blocks. But these elements, components, regions, layers and / or blocks should not be limited by these terms. These terms are limited to identifying a single element, component, region, layer and / or block. Therefore, a first element, component, region, layer and / or block hereinafter may also be referred to as a second element, component, region, layer and / or block without departing from the spirit of the present invention.

[0052] In this article, "a" and "the" can generally refer to a single or a plurality, unless the articles are specifically limited. It will be further understood that "comprises", "comprises", "has" and similar words used herein indicate the feat...

Abstract

A pixel circuit includes a driving circuit, a data writing circuit, and a modulation circuit. The driving circuit is turned on in response to the potential of the first node to output a driving current to drive the light emitting element. The data writing circuit is turned on in response to the gate signal to store the data voltage. The modulation circuit outputs the data voltage to the second node in response to the potential change of the time control signal, and adjusts the potential of the first node to the first voltage according to the potential of the second node to turn on the drivingcircuit.

Description

technical field [0001] The present invention relates to a pixel circuit and a pixel driving method, in particular to a pixel circuit responding to a time control signal. Background technique [0002] Pixel circuits are used to drive and display different picture results. Since the size of the circuit area will affect the manufacturing process of the product, and the brightness of the general pixel circuit in the market is relatively low at low frequencies, resulting in reduced user experience. Contents of the invention [0003] In order to solve the above problems, the present invention provides a pixel circuit, which includes a driving circuit, a data writing circuit and a modulating circuit. The driving circuit is turned on in response to the potential of the first node, and outputs a driving current to drive the light emitting element. The data writing circuit is turned on in response to the gate signal to store the data voltage. The modulation circuit outputs the da...
