Abstract

A display device includes a light emitting layer, a light adjusting layer and a display layer. The light emitting layer includes a plurality of light emitting units. The light adjusting layer is disposed to be corresponding to the light emitting layer. The display layer is disposed on the light adjusting layer. The light adjusting layer includes at least one light adjusting structure corresponding to at least three of the plurality of light emitting units.

First claim

What is claimed is:

1. A display device, comprising:
a backlight source;
a light adjusting layer disposed on the backlight source;
a light adjusting panel disposed on the backlight source, and the light adjusting panel comprising a plurality of opening units, a first light adjusting substrate and a second light adjusting substrate; and
a display layer disposed on the light adjusting layer;
wherein the light adjusting layer comprises at least one light adjusting structure corresponding to at least three of the plurality of opening units; and
wherein the second light adjusting substrate is disposed between the display layer and the first light adjusting substrate, the light adjusting layer is disposed on the first light adjusting substrate, the first light adjusting substrate has a first surface away from the display layer and a second surface close to the display layer, and the light adjusting layer is disposed on the first surface.

2. The display device according to claim 1 , wherein the light adjusting layer is disposed between the display layer and the light adjusting panel.

3. The display device according to claim 1 , wherein the at least one light adjusting structure comprises one or more of a lens structure, a prism structure and a shielding structure.

4. The display device according to claim 1 , wherein the display device has a display region divided into a plurality of regions, the light adjusting panel comprises a plurality of light switching structures, each of the plurality of light switching structures has one of the plurality of opening units, and switching statuses of the plurality of light switching structures in each of the plurality of regions are controlled respectively.

5. The display device according to claim 1 , further comprising a position tracking sensor configured to track a position of a user.

6. The display device according to claim 5 , wherein the light adjusting panel comprises a plurality of light switching structures, each of the plurality of light switching structures has one of the plurality of opening units, a switching status of each of the plurality of light switching structures is adjusted based on the position of the user.

7. The display device according to claim 1 , wherein the display layer comprises liquid crystal or electrophoresis.
