  • Patent number: 10748502
    Abstract: A driving method of a display panel and a display device are provided. The method includes: receiving an external display data; changing a luminance signal of the sub-pixel corresponding to each pixel unit of a display panel in the display data, to generate a data signal; sending the data signal; wherein the luminance of one sub-pixel in the two adjacent sub-pixels in the same color after being changed, is greater than the luminance before being changed, and the luminance of the other sub-pixel after being changed, is smaller than the luminance before being changed. The present disclosure can make the orientation of the liquid crystal molecules in the liquid crystal display panel may be more rich, and the chromaticity viewing angle of the liquid crystal display panel may be improved.

  • Patent number: 10629142
    Abstract: A liquid crystal display device is provided. The liquid crystal display device includes a plurality of sub-pixels arranged in matrix, each sub-pixels is an eight domains structure; in a frame image, the data signals of the sub-pixels in two adjacent columns have opposite polarities, and in two adjacent frame images, the data signals of the same sub-pixel have opposite polarities; each two adjacent sub-pixels in a row direction are a sub-pixel group, in two adjacent sub-pixel groups, the sub-pixels in one sub-pixel group display a brightness of a first display gray scale corresponding to the sub-pixels, the sub-pixels in another sub-pixel group display a brightness of a second display gray scale corresponding to the sub-pixels; by performing the color shift compensation process on the data signals of the sub-pixels in the eight-domain structure, the color viewing angle and the viewing experience of the liquid crystal display device could be improved.

  • Patent number: 10553165
    Abstract: The present disclosure provides a method and an apparatus of detecting high-frequency components in an image. The method using a first grayscale difference, a second grayscale difference to calculate the target grayscale difference with the target grayscale difference algorithm, comparing the target grayscale difference with a preset grayscale threshold value to determine whether the image pixel to be detected is a high-frequency image pixel, and adjusting the actual grayscale value of the high-frequency image pixel to reduce the difference between the actual grayscale value of the high-frequency image pixel and the original grayscale value. It can optimize the detection process of high-frequency components in the image and improve the poor display caused by the color shift compensation algorithm to improve the display quality.

  • Patent number: 10388235
    Abstract: A display driving method and device is provided. The display driving method determines whether each image pixel is within a range of skin color in accordance with the original grayscale data of the image pixel, and performs color casting compensation only on the image pixels within the range of skin color but not on other image pixels. The effects of color casting compensation and display are improved, and the granular feeling caused due to the color casting compensation is reduced.
