Abstract

The invention discloses a picture processing method, its device, and a display device. The method includes: judging whether there is a solid-color pixel area in the picture to be displayed; if so, performing pixel voltage correction on pixels in the non-solid-color pixel area in the same column as each pixel in the solid-color pixel area according to preset conditions, and outputting and displaying the corrected picture ; If not, output the screen to be displayed. The picture processing device includes: a judging module for judging whether there is a solid-color pixel area in the picture to be displayed; Voltage correction, output and display the corrected screen. The picture processing method of the embodiment of the present invention improves the color bar crosstalk phenomenon, and at the same time, the technical solution is easy to implement without increasing the power consumption of the display device. An embodiment of the present invention also provides a display device, including the above-mentioned image processing device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a picture processing method and its device, and a display device. Background technique [0002] Under certain conditions, liquid crystal display panels will produce some phenomena that affect the image quality, such as flicker (Flicer), green (Greenish), crosstalk (Crosstalk), etc. processing to achieve a better display effect. [0003] For image detection, some detection methods have been proposed in the prior art, which can detect image types such as flicker, noise, and thermal power consumption, and improve the image by changing polarity and other processing. [0004] The inventors of the present application found that, for the color bar crosstalk phenomenon, existing detection and processing methods have defects such as difficulty in implementation and increased power consumption. Contents of the invention [0005] The technical problem to be solved by the embodi...
