Display device and driving method thereof

A driving method of a display device, comprising:

• generating M-frame sub-picture information and M-frame raster picture information according to information of a current picture frame to be displayed, in a condition that an anti-peep mode is enabled;
• controlling a sub-display panel in the display device to sequentially display M sub-pictures according to the M-frame sub-picture information, controlling pixel rows of the sub-pictures to be periodically arranged and displayed as first pixel groups, and controlling the first pixel groups of the pixel rows corresponding to the sub-pictures to be mutually misaligned, so that the M sub-pictures form the current picture frame when continuously displayed, wherein each of the first pixel groups comprises at least one display pixel and at least one first light-shielding pixel arranged in sequence;
• and
• controlling a sub-raster panel in the display device to sequentially display M raster pictures according to the M-frame raster picture information, and controlling pixel rows of the raster pictures to be periodically arranged and displayed as second pixel groups, wherein each of the second pixel groups comprises:
• a transparent pixel corresponding to the display pixel in a sub-picture currently displayed and a second light-shielding pixel corresponding to the first light-shielding pixel;
• and at a same display moment, an orthographic projection of the transparent pixel in the sub-display panel overlaps an area where the display pixel is located, and an orthographic projection of the second light-shielding pixel in the sub-display panel overlaps an area where the first light-shielding pixel is located.
