Display Device and Driving Method Thereof

摘要

A display device and driving method thereof are disclosed. The display device includes a display screen, including a plurality of sub-pixels arranged in the form of a matrix, colors of the sub-pixels in the same column including all colors necessary for display by the display screen; a grating disposed on top of the display screen, including light-transmissive regions and light-shading regions that are arranged alternately, the light-transmissive regions being in parallel to each column of the sub-pixels; a rolling structure, located between the display screen and the grating; and a push mechanism, for pushing the grating and/or the display screen, so that relative position of the grating and the display screen is switchable between a first state and a second state, and switchover between a dual viewing field display effect and an anti-spy display effect is achieved for the display device.

1. A display device, comprising
a display screen, including a plurality of sub-pixels arranged in the form of a matrix, colors of the sub-pixels in the same column including all colors necessary for display by the display screen; a grating, disposed on top of the display screen, and including light-transmissive regions and light-shading regions that are arranged alternately, the light-transmissive regions being each in parallel to columns of the sub-pixels; a rolling structure, located between the display screen and the grating; and a push mechanism, for pushing the grating and/or the display screen, so that relative position of the grating and the display screen is switchable between a first state and a second state; wherein, the first state is that, a vertical projection of each of the light-transmissive regions on the display screen stretches across corresponding two columns of the sub-pixels that are adjacent, and completely or partially overlap with areas where the corresponding two columns of the sub-pixels that are adjacent are located; the second state is that, a vertical projection of each of the light-transmissive regions on the display screen completely or partially overlaps with areas where corresponding only one column of the sub-pixels are located.
