Embodiment 1

[0036] see figure 1 and figure 2 , the display device provided by the embodiment of the present invention includes: an anti-peeping backlight module 3, a display panel 1 and an adjustment unit 2, the display panel 1 is located on the light emitting surface of the anti-peeping backlight module 3, and the anti-peeping backlight module 3 is used to emit anti-peeping Peeping backlight; the display device includes an anti-peeping closed state and an anti-peeping open state; wherein, in the anti-peeping closed state, the adjustment unit 2 is used to increase the divergence angle of the anti-peeping backlight to obtain divergent light; in the anti-peeping open state, adjust Unit 2 is used to maintain the divergence angle of the anti-peeping backlight to obtain anti-peeping light.

[0037] In the process of specific implementation, the display method of the display device provided by the embodiment of the present invention is as follows:

[0038] In the anti-peeping off state: the ...

Embodiment 2

[0092] This embodiment provides a display method for a display device, and the display method for a display device is applied to the display device in Embodiment 1. The display methods include:

[0093] In the anti-peeping off state: the anti-peeping backlight module 3 emits an anti-peeping backlight, and uses the adjustment unit 2 to increase the divergence angle of the anti-peeping backlight to obtain divergent light;

[0094] In the anti-peeping open state: the anti-peeping backlight module 3 emits the anti-peeping backlight, and the divergence angle of the anti-peeping backlight is maintained by the adjustment unit 2 to obtain the anti-peeping light.

[0095] Compared with the prior art, the anti-peeping display method provided by the embodiment of the present invention has the same beneficial effects as the display device provided by the first embodiment above, and details are not repeated here.

[0096] It can be understood that the methods for obtaining divergent light...

Abstract

The invention discloses a display device and a display method, and relates to the field of display technologies. Normal display modes and peep-proof display modes of the display device can be switched over. The display device comprises a peep-proof backlight module, a display panel and an adjusting unit. The peep-proof backlight module is used for emitting peep-proof backlight; the display device can be in peep-proof off states and peep-proof on states; the adjusting unit is used for enlarging divergence angles of the peep-proof backlight to obtain divergent light when the display device is in the peep-proof off states; the adjusting unit is used for keeping the divergence angles of the peep-proof backlight to obtain peep-proof light when the display device is in the peep-proof on states. The display method is implemented by the aid of the display device in the technical scheme. The display device and the display method have the advantage that the display device and the display method can be used for safety display of display equipment.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a display method. Background technique [0002] With the development of network technology, more and more people are doing shopping or account transactions on the Internet. During the above operations, operators often need to display devices such as computers, mobile phones, automatic teller machines, and automatic ticket machines. Entering personal information on the Internet can easily cause personal information leakage. Therefore, the anti-peeping function of the display device has received more and more attention. [0003] The anti-peeping display device in the prior art mainly includes a display device and glasses, wherein, only one side of the array substrate is provided with a lower polarizer on the display device, and the lens of the glasses is a polarizer corresponding to the lower polarizer on the array substrate. The operator wears glass...
