Problems solved by technology

Since different polarity inversion driving methods correspond to different pixel polarity distributions, switching the polarity inversion driving method may cause the same pixel to have the same polarity in adjacent frames. Pixels with the same polarity will instantly show vertically distributed bright bands on the display panel, resulting in flickering with uneven brightness distribution on the screen

Embodiment Construction

[0021] figure 1 is a schematic diagram of a display device according to an embodiment of the present invention, please refer to figure 1 . The display device includes a display panel 120 and a display driver. The display driver may include, for example, a gate driver 122 , a source driver 124 and a timing controller 126 . The display panel 120 has a plurality of pixels (not shown) arranged in an array. The gate driver 122 and the source driver 124 are coupled to the display panel 120 and respectively provide driving signals to the display panel 120, so as to drive the pixels on the display panel 120 by the driving signals. scan lines (not marked) and data lines (not marked) to display the image to be displayed. The timing controller 126 is coupled to the gate driver 122 and the source driver 124 and provides control signals to make the gate driver 122 and the source driver 124 generate driving signals.

Abstract

A display device and a gray scale compensation method for a display panel. The timing controller detects the positions of pixels with the same polarity during the display period of two adjacent frames on the display panel, and performs gray scale compensation for the pixels with the same polarity during the display period of two adjacent frames.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to a display device and a gray scale compensation method of a display panel. Background technique [0002] In order to meet the requirements of high speed, high performance, light weight and short size of modern products, all electronic components are actively developing towards miniaturization. Various portable electronic devices have gradually become mainstream, such as: notebook computers (Note Book), mobile phones (Cell Phone), electronic dictionaries, personal digital assistants (Personal Digital Assistant, PDA), Internet machines (web pad) and Tablet PC, etc. For image display panels of portable electronic devices, in order to meet the needs of product miniaturization, liquid crystal display panels with excellent space utilization efficiency, high image quality, low power consumption, and no radiation have been widely used. use. [0003] The rotation direction of the liqu...
