Double-vision display device and method for driving the same

摘要

Embodiments of the present invention provide a double-vision display device comprising a display panel and a grating, wherein the display panel includes a plurality of sub-pixels, and, the grating includes light shading regions and light transmittance regions alternately arranged in a first direction. A distance between midlines of two adjacent ones of the light transmittance regions in each row of the light transmittance regions along the first direction is at least four times as large as a length of one of the sub-pixels along the first direction. Meanwhile, embodiments of the present invention also provide a method for driving the abovementioned double-vision display device. With the abovementioned double-vision display device and the method for driving the same, the double-vision display function is guaranteed while allowing a greater distance between a plane where the grating is located and a plane where the sub-pixels are located.
