Embodiment Construction

[0039] Hereinafter, various embodiments of the present invention will be illustrated by means of drawings to describe the present invention in detail. Inventive concepts may however be embodied in many different forms and should not be construed as limited to the illustrative embodiments set forth herein.

[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 request item does not use the difference in name as the way to distinguish components, but the difference in the overall technology of 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 ...

Abstract

The invention discloses a driving circuit of a display panel including a common voltage generating circuit. The common voltage generating circuit is coupled to a plurality of common electrodes of a display panel, and provides a plurality of common voltages to the common electrodes, respectively. During one frame, the common voltage generating circuit changes a voltage level of the common voltagesat different times.

Description

technical field [0001] The present invention relates to a driving circuit and a driving method of a display panel and a display module thereof, in particular to a driving circuit and a driving method of a display panel and a display module thereof capable of effectively reducing screen flicker. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) is one of most liquid crystal displays. It uses thin film transistor technology to improve image quality and is often used in TVs, flat panel displays and projectors. [0003] In order not to affect the arrangement and penetration of liquid crystal molecules, and to avoid the DC blocking effect of the alignment film and the afterimage caused by DC residue, the polarity of the electric field applied to the liquid crystal molecules must be reversed, that is, at different times with An electric field in the opposite direction is applied to the liquid crystal molecules. [0004] Common polarity ...
