To improve the vertical flicker, it is usually preferred to use symmetric code to minimize the brightness difference between the positive and negative frames to reduce the vertical flicker. But due to the need to balance the panel display resolution (U %) at the same time and the symmetric code will suffer other panel stylish, the degree of reduction is very limited.
On this basis, if the level of the vertical flicker is still unacceptable, the driving mode of a one-plus-two-line point reversal arrangement (1+2Line) or a two-line point reversal arrangement (2Line) will be used (as depicted in
The embodiments of the present application provide a pixel driving architecture, a display panel having the pixel driving architecture, and a display device having the display panel to solve the problem that the degree of reduction of vertical flicker by the existing column inversion pixel driving architecture is limited.
The embodiment of the application provides a pixel driving architecture. The pixel driving architecture includes a plurality of pixel units and a plurality of data lines. The plurality of pixel units are arranged in parallel and at intervals along a row direction, each of the pixel units includes a plurality of sub-pixels arranged at intervals along a column direction. The plurality of data lines are arranged along the column direction and arranged at intervals between the plurality of pixel units along the row direction, one of the pixel units corresponds to one of the data lines, and the sub-pixels in the one of the pixel units are respectively connected with the one of the data lines. When displaying an Nth frame of image, a polarity arrangement of the sub-pixels in the pixel units is one of following three arrangements: a first arrangement is that polarities of the sub-pixels in the pixel unit are same and polarities of the sub-pixels in two adjacent pixel units are opposite, forming a column inversion arrangement of the polarities of the sub-pixels in the pixel unit: a second arrangement is that the sub-pixels in the M-th row in the pixel unit have a same polarity as the sub-pixels in the (M+1)-th row, the sub-pixels in the (M+2)-th row have an opposite polarity to the sub-pixels in the M-th row, and the polarities of the sub-pixels in two adjacent pixel units are opposite, forming a one-plus-two-line point inversion arrangement of the polarities of the sub-pixels in the pixel unit: and a third arrangement is that the polarities of the sub-pixels in the M-th row and the sub-pixels in the (M+1)-th row are same, and the polarities of the sub-pixels in the (M+2)-th row and the sub-pixels in the (M+3)-th row are opposite to the polarity of the sub-pixels in the M-th row, forming a two-line point inversion arrangement of the polarities of the sub-pixels in the pixel unit. When displaying an (N+1)-th frame of image, the polarity arrangement of the sub-pixels in the pixel unit is another one of the three arrangements. When displaying the (N+2)-th frame of image, the polarity of the sub-pixels in the pixel unit is opposite to the polarity of the sub-pixels when the pixel unit displays the N-th frame of image. When displaying the (N+3)-th frame of image, the polarity of the sub-pixels in the pixel unit is opposite to the polarity of the sub-pixels when the pixel unit displays the (N+1)-th frame of image. Both M and N are positive integers.
Further, the polarity arrangement of a single sub-pixel in the pixel unit uses 4 frames as a period cycle.

When displaying the (N+1)-th frame of image, the polarity arrangement of the sub-pixels in the pixel unit is the one-plus-two-line point inversion arrangement or the two-line point inversion arrangement. When displaying the (N+2)-th frame of image, the polarity of the sub-pixels in the pixel unit is opposite to the polarity of the sub-pixels when the pixel unit displays the N-th frame of image. When displaying the (N+3)-th frame of image, the polarity of the sub-pixels in the pixel unit is opposite to the polarity of the sub-pixels when the pixel unit displays the (N+1)-th frame of image.
Further, when displaying the N-th frame of image, the arrangement of the polarities of the sub-pixels in the pixel unit is the one-plus-two-line point inversion arrangement or the two-line point inversion arrangement. When displaying the (N+1)-th frame of image, the arrangement of the polarities of the sub-pixels in the pixel unit is the column inversion arrangement. When displaying the (N+2)-th frame of image, the polarity of the sub-pixels in the pixel unit is opposite to the polarity of the sub-pixels when the pixel unit displays the N-th frame of image.
