Abstract
This disclosure relates to a display panel, a control method thereof, a display device and a display system comprising such a display panel. The display panel includes a plurality of pixel units. Each pixel unit has a plurality of subpixels Each subpixel has a display subpixel and an interference subpixel. Additionally, the interference subpixel and the display subpixel are different in at least one of color and gray scale. The display panel also includes a first control unit configured to control the display subpixel to be switched on during a first period of time in each display period, and to control the interference subpixel to be switched off during the first period of time in each display period and switched on during a second period of time in each display period.
