Embodiment 1

[0045] figure 1 It is a schematic structural diagram of a display device provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the display device includes a display panel 5 and a first liquid crystal cell 4 , and the first liquid crystal cell 4 is arranged on the light emitting side of the display panel 5 . The display panel 5 is used to form display light according to the position of the human eye, and the propagation direction of the display light corresponds to the position of the human eye.

[0046] The first liquid crystal cell 4 is used for transmitting the display light when the first display mode is selected. In this embodiment, the first display mode is the private mode. When the display device is in the private mode, the display panel 5 adjusts the propagation direction of the incident light in real time according to the human eye tracking technology, thereby forming the display light. At this time The first liquid crystal cell 4 transmits ...

Embodiment 2

[0055] Figure 5 It is a flowchart of a working method of a display device provided by Embodiment 2 of the present invention. see figure 1 and Figure 5 , the display device includes a display panel 5 and a first liquid crystal cell 4 , and the first liquid crystal cell 4 is arranged on the light emitting side of the display panel 5 .

[0056] The working method of the display device includes:

[0057] Step 1001, the display panel forms a display light according to the human eye tracking technology, and the propagation direction of the display light corresponds to the position of the human eye.

[0058] see figure 1 , the display panel 5 includes a second liquid crystal cell 3, the second liquid crystal cell 3 includes a first substrate 301 and a second substrate 302, and a plurality of Light adjustment unit 31. The display panel forms display light according to the position of the human eye, and the step of the propagation direction of the display light corresponding to...

Abstract

The invention discloses a display device and a working method thereof. The display device comprises a display panel and a first liquid crystal box, wherein the first liquid crystal box is arranged on the light emergency side of the display panel. When the display device is in a private mode, the display panel adjusts the incident light propagation direction in real time by adopting a human eye tracking technology and accordingly forms display light, the first liquid crystal box transmits the display light at the moment to ensure that the display light reaches the position where the human eyes are located at a certain angle, accordingly accurate display light control is achieved, and the peep preventing purpose is achieved. When the display device is in a sharing mode, the working state of the display panel is invariant, the first liquid crystal box conducts multi-angle scattering on the display light fixed in propagation direction at the moment, and accordingly the purpose of viewing of multiple persons is achieved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a working method thereof. Background technique [0002] In the field of display technology, users have higher and higher requirements for confidentiality when displaying information on a display device. When the existing display device displays information, not only the user can see the display screen of the display device, but also other people can see the display screen of the display device. Therefore, the existing display device has poor security. In addition, with the rapid development of display technology, display devices are widely used in various fields of life, and the application occasions of display devices are also becoming diversified. Therefore, the display mode of the existing security display device is relatively simple, which obviously cannot meet the diversified requirements of application scenarios. Contents of the invention ...
