PIXEL STRUCTURE, DISPLAY PANEL WITH A PIXEL STRUCTURE, AND DISPLAY DEVICE WITH A PIXEL STRUCTURE
The present invention provides a pixel structure. In sub-pixels of the same color group and polarity of each of the pixel units, polarities of data lines on left and right sides of half of the sub-pixels are positive and negative respectively, polarities of data lines on left and right sides of another half of the sub-pixels are negative and positive respectively. When the same pixel unit switches between display images of two frames, a brightness thereof is unchanged, which prevents low grayscale flickering occurring during switching between the display images of the two frames. The present invention also provides a display panel with the pixel structure and a display device with the pixel structure.
