DISPLAY PANEL AND CONTROL METHOD THEREFOR, AND DISPLAY DEVICE AND DISPLAY SYSTEM

Document Type and Number:

WIPO Patent Application WO/2017/161674

Kind Code:

A1

Abstract:

A display panel and a control method therefor, and a display device and display system comprising the display panel. The display panel comprises: multiple display units, wherein each pixel unit (10) comprises multiple subpixels, each subpixel comprises a display subpixel (11) and an interference subpixel (12), and the color and/or the gray level of the interference subpixel (12) is different from that of the display subpixel (11); and a first control unit configured to control the display subpixel (11) to be turned on in a first time period of each display cycle, and to control the interference subpixel (12) to be turned off in the first time period of each display cycle and to be turned on in a second time period of each display cycle. An image viewed by a viewer in the second time period is different from that in the first time period. However, human eyes have persistence of vision for a changing image, and therefore, the viewer views a superposed image of an interference image and a normal image, and therefore cannot clearly view a normally outputted image. Whereby, by using a particular viewing device, an intentional user of the display panel can receive only an image in a first time period, and other users that do not use such a viewing device cannot clearly view an outputted image, thereby effectively preventing a normal image outputted by the display panel from being recognized by others.
