The invention discloses a display device to solve the problems that an anti-peeping display device in the prior art is large in visual angle, large in thickness and wide in frame. The display device comprises a first substrate, a second substrate, a liquid crystal layer and an electrode structure set, wherein the first substrate and the second substrate are oppositely arranged, and the liquid crystal layer and the electrode structure set are located between the first substrate and the second substrate; one side, facing the liquid crystal layer, of the first substrate is provided with a plurality of collimated light-emitting structures which are distributed in an array; a plurality of concave-convex structures are arranged on one side, facing the liquid crystal layer, of the second substrate; the liquid crystal layer has a birefringence, and is configured to enable the refractive index to be the same as that of the concave-convex structures when the voltage difference generated by the electrode structure group is a first voltage to enable the light emitted by the collimation light-emitting structure to be emitted at an original angle, and when the voltage difference generated by theelectrode structure group is a second voltage, the refractive index of the collimation light-emitting structure is different from that of the concave-convex structures, so that light emitted by the collimation light-emitting structure is scattered and then emitted out.
Description
Technical field[0001]The present invention relates to the field of display technology, and in particular to a display device.Background technique[0002]At present, the development of anti-peep technology has become the outlet for the development of next-generation display technology. How to develop a new ultra-thin and ultra-narrow anti-peep design has become a key project for the next technology development of major panel companies. The anti-peep display products currently on the market have the following 4 implementation methods:[0003]1. Privacy film backlight + display panel mode: This method places a privacy film in the backlight, and uses the shutter characteristics of the privacy film to force the light passing through the privacy film to collimate. This method has low brightness gain (private protection film). The backlight brightness can be reduced by 40%) and defects such as high power consumption, large thickness, and inability to switch freely;[0004]2. Conventional backlig...
