Embodiment Construction

[0034] Aiming at the problem in the prior art that the anti-peeping effect of the anti-peeping display device is poor, an embodiment of the present invention provides a display device.

[0035] The specific implementation manner of the display device provided by the embodiment of the present invention will be described in detail below with reference to the accompanying drawings. The thickness and shape of each film layer in the drawings do not reflect the real scale, and the purpose is only to illustrate the content of the present invention.

[0036] An embodiment of the present invention provides a display device, such as figure 1 As shown, it includes: a light guide plate 11, a first light source 12 and a second light source 13 arranged on the light incident side of the light guide plate 11, a plurality of light extraction structures 14 located on the light output side of the light guide plate 11, respectively located in each light extraction structure 14 a plurality of dis...

Abstract

The invention discloses a display device. The display device comprises a light guiding plate, a first light source, a second light source, multiple light taking structures, multiple display units anda control unit. Each display unit comprises a blue-phase liquid crystal layer, first and second electrodes located on the same side of the blue-phase liquid crystal layer and a light-shading structure. Light-shading structures correspond to the multiple light taking structures in a one to one way, the light taking structures are located in a corresponding light-shading structure range. The first light source and the second light source produce collimated polarized light, and polarized light of the first light source and polarized light of the second light source are perpendicular to each other. The control unit is used for only controlling emergent light ways of the first light source in a peeping-prevention display mode so as to make blue-phase liquid crystal layers equivalent to concavelens structures and used for controlling emergent light rays of the second light source so as to make the blue-phase liquid crystal layers equivalent to convex lens structures in a normal display mode. The display device is simple in structure, simple in mode switching way and good in peeping-prevention display effect, and the two ways are not likely confused.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device. Background technique [0002] At present, with the development of display technology and network technology, more and more people are doing shopping or account transactions on the Internet. Entering personal information on display devices such as ticket machines can easily cause leakage of personal information. Therefore, the anti-peeping performance of display devices has attracted more and more attention, and strives to ensure the safety of personal information of operators. [0003] In the prior art, the structure of the anti-peeping display device is relatively complicated, and the overall device size is relatively thick. In addition, due to the limitation of the structure of the anti-peeping display device itself, the light path of the anti-peeping display mode and the light path of the normal display mode are unavoidable. There is an overlap, which makes...
