Abstract

The invention provides a picture detection method and a picture detection device, which are used to judge whether there is a bad picture in the picture data displayed by the display panel, so as to achieve the purpose of improving the picture quality. The method for detecting a picture includes: collecting picture data that needs to be displayed by a display panel; and judging whether the picture data will produce a bad picture according to preset detection conditions of bad picture types.

Description

technical field [0001] The invention relates to the field of liquid crystal display panel systems, in particular to a picture detection method and a picture detection device. Background technique [0002] In the prior art, under certain conditions, liquid crystal display panels may produce some phenomena that affect picture quality, such as flicker, greenish, crosstalk, I / S, H-Block, and the like. Moreover, these phenomena can be improved by changing the polarity of POL or DateIC, but at present, before displaying the image, the image data that needs to be displayed on the display panel is not detected, resulting in bad images on the display panel. [0003] For example: to participate in figure 1 , in the 2LINE INVERSION working mode, the display panel is likely to produce a "back" window picture, which will cause the Crosstalk phenomenon and affect the picture quality; in the 1LINE INVERSION working mode, if the picture data of adjacent pixel units in each row of pixel uni...
