Problems solved by technology

[0007] If the maximum color crosstalk ratio of the display panel exceeds the specifications specified by the customer (for example, the maximum color crosstalk ratio is 20%), it means that the display quality of the display panel may be lower than that of other display panels under the driver settings of the customer. Poor, especially the grayscale brightness display error may be more obvious, so it is not accepted by customers

Embodiment Construction

[0038] Please refer to figure 1 , figure 1 A schematic circuit diagram of a display device provided by an embodiment of the present invention is shown. The display device 100 of this embodiment is a liquid crystal display device including a display panel 110 , a backlight module 120 and a driving unit 130 . The driving unit 130 is coupled to the display panel 110 and the backlight module 120 for providing driving data signals and voltage signals for the display panel 110 and the backlight module 120 . In this embodiment, the driving unit 130 can use the grayscale compensation method (that is, the crosstalk compensation method) to reduce or eliminate the sub-pixel electrode (pixel electrode) (such as the red sub-pixel R) and Adjacent sub-pixel electrodes (green sub-pixel G) or data lines (not shown) are coupled with each other to generate crosstalk, thereby improving the quality of the display image of the display panel.

[0039] Furthermore, the display panel 110 has a pixe...

Abstract

The embodiment of the invention provides a crosstalk compensation method of a display panel and a display device of the crosstalk compensation method. The crosstalk compensation method includes the following steps that firstly, a gray scale compensation range is set, wherein the gray scale compensation range includes gray scales ranging between the lowest gray scale and the highest gray scale; secondly, a lookup table is established to record a plurality of compensation values which correspond to the gray scales in the gray scale compensation range respectively; thirdly, whether the gray scale of first-color sub-pixels on the display panel is within the gray scale compensation range or not is judged, if yes, a corresponding compensation value is selected from the lookup table to adjust the initial gray scale of second-color sub-pixels to a corrected gray scale, and otherwise the initial gray scale of the second-color sub-pixels is maintained, wherein the first-color sub-pixels are adjacent to the second-color sub-pixels.

Description

technical field [0001] The present invention relates to a compensation method for a display panel and a display device thereof, in particular to a crosstalk compensation method for a display panel and a display device thereof. Background technique [0002] Display panels have the advantages of light weight, small size, low power consumption, and low battery, and have been widely used in various communication and consumer electronics products, such as TVs, notebook computers, mobile phones, and personal digital assistants. [0003] In order to increase the aperture ratio of pixels on the display panel to obtain higher penetration or lower power consumption, the distance between adjacent sub-pixel electrodes is generally reduced, and even the distance between the sub-pixel electrodes and adjacent sub-pixels is reduced. Data lines overlap. However, this approach will lead to increased capacitive coupling, which in turn will cause display problems such as crosstalk. At present...
