Claim 3:
4. A display device, comprising:
a detection module, configured to detect a current pixel inversion mode of the display device;
a data signal generation module, configured to generate data signals corresponding to pixel polarities of a current frame, and generate first data signals for a next frame according to the pixel polarities of the current frame and an inversion mode of the display device;
a pixel recording module, configured to record pixel bright-or-dark values of pixels; and
verification and determination module, configured to verify and determine whether the next frame is an overload image based on the pixel bright-or-dark values and grayscale values of an image corresponding to the first data signals;
wherein in response to determining that the next frame corresponding to the first data signals is an overload image, the data signal generation module is configured to modify the pixel polarities corresponding to the first data signals, and generate and output second data signals to drive the display device to display the next frame;
and in response to determining the next frame corresponding to the first data signals is a non-overload image, the data signal generation module is configured to output the first data signals to drive the display device to display the next frame;
wherein when the inversion mode of the display device is dot inversion, the overload image is divided into a plurality of pixel sections where each pixel section comprises at least 2*4 pixels, and wherein a pixel driving architecture in each pixel section is as follows:
the grayscale values corresponding to the pixels in S4n+1 column are all bright; the grayscale values corresponding to the pixels in S4n+2 column are alternately bright, dark, bright, and dark; the grayscale values corresponding to the pixels in S4n+3 column are all dark; and the grayscale values corresponding to the pixels in S4n+4 column are alternately dark, bright, dark, and bright;
when the pixel is displayed as bright, the corresponding pixel bright-or-dark value is 111, and when a pixel is displayed as dark, the corresponding pixel bright-or-dark value is 000;
wherein the step of determining whether the next frame is an overload image based on the pixel bright-or-dark values and the grayscale values corresponding to the next frame and the pixel bright-or-dark values and the grayscale values of the overload image comprises:
in response to determining that the pixel bright-or-dark values and grayscale values of every four columns of pixels corresponding to the next frame are consistent with the pixel bright-or-dark values and grayscale values of every four columns of pixels of the overload image, determining that the next frame is the overload image.
