Embodiment Construction

[0039] In order to make the structural features of the present invention and the achieved effects have a further understanding and recognition, preferred embodiments and detailed descriptions are specially used, which are described as follows:

[0040] Some terms are used in the specification and claims to refer to specific components. However, those with ordinary knowledge in the technical field of the present invention should understand that manufacturers may use different terms to refer to the same component. Moreover, this specification and The claim item does not use the difference in name as the way to distinguish the components, but the difference in the overall technology of the components as the criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". Furthermore, the term "coupled" herein includes any direct and indirect means of connection. Therefore, i...

Abstract

The invention relates to a driving circuit of a display panel. The driving circuit drives a plurality of pixel structures of the display panel. Each pixel structure comprises a light-emitting element, and the light-emitting element is coupled between a first voltage and a second voltage. The driving circuit comprises a power supply circuit which is coupled with the pixel structures and provides a first voltage and a second voltage. By adjusting the first voltage or / and the second voltage, a voltage between the first voltage and the second voltage is adjusted, so that a current flowing through the light-emitting elements of the pixel structures can be adjusted, and flicker of the display panel can be reduced.

Description

technical field [0001] The present invention relates to a driving circuit, in particular to a driving circuit of a display panel, which can reduce picture flickering. Background technique [0002] A display panel is one of the necessary equipments for an electronic device with a display function, and is used for displaying images. Liquid crystal display panels and organic light emitting diode panels are the main trends now. The organic light emitting diode display panel includes a plurality of pixel structures, each pixel structure includes a light-emitting element, and the driving circuit drives the light-emitting elements of the pixel structures of the display panel to emit light to display images. However, the organic light emitting diodes may flicker when displaying images, especially when the frame rate of the display panel is low, that is, the frame is updated every long time, and the flicker is more obvious. [0003] Therefore, the present invention proposes a drivi...
