Abstract

The disclosure provides an electronic device and a display method thereof. The electronic device includes a display panel and a light source module. The light source module is disposed at a side of the display panel. The light source module includes a first group of light-emitting units and a second group of light-emitting units that are alternately arranged, wherein the first group of light-emitting units and the second group of light-emitting units emit a light alternately, and each of a plurality of display pixels is adapted to alternately receive the light from the first group of light-emitting units and the second group of light-emitting units.

First claim

What is claimed is:

1. An electronic device, comprising:
a display panel comprising a plurality of display pixels; and
a light source module disposed at a side of the display panel, wherein the light source module comprises a first group of light-emitting units and a second group of light-emitting units that are alternately arranged, wherein the first group of light-emitting units and the second group of light-emitting units emit a light alternately, and each of the plurality of display pixels is adapted to alternately receive the light from the first group of light-emitting units and the second group of light-emitting units, wherein the first group of light-emitting units and the second group of light-emitting units each comprise a plurality of light-emitting units of different colors.

2. The electronic device of claim 1 , wherein the first group of light-emitting units and the second group of light-emitting units alternately emit the light under a stereoscopic display operation.

3. The electronic device of claim 1 , wherein the first group of light-emitting units and the second group of light-emitting units emit light of different colors.

4. The electronic device of claim 3 , wherein at least one light-emitting unit of the first group of light-emitting units and at least one light-emitting unit of the second group of light-emitting units are located in a same light-emitting region.

5. The electronic device of claim 1 , further comprising an electronically controlled diffuser disposed between the display panel and the light source module.

6. The electronic device of claim 1 , further comprising a lens array disposed between the display panel and the light source module.

7. The electronic device of claim 6 , wherein the lens array comprises a plurality of lenticular lens structures.

8. The electronic device of claim 7 , further comprising a directional diffuser disposed between the lens array and the display panel, and an extending direction of each of the plurality of lenticular lens structures corresponds to a main diffusion direction of the directional diffuser.

9. The electronic device of claim 1 , wherein light-emitting units of the first group of light-emitting units and the second group of light-emitting units are mini light-emitting diodes or micro light-emitting diodes.

10. The electronic device of claim 1 , wherein when the first group of light-emitting units emit the light, one of the display pixels displays a first view field image information transmitted toward a first view field direction; and when the second group of light-emitting units emit the light, the one of the display pixels displays a second view field image information transmitted toward a second view field direction.

11. The electronic device of claim 10 , wherein the first view field image information is different from the second view field image information.

12. The electronic device of claim 1 , wherein when the first group of light-emitting units emit the light, one of the display pixels displays a first view field image information transmitted toward a view field direction; and when the second group of light-emitting units emit the light, another of the display pixels displays a second view field image information transmitted toward the view field direction.

13. The electronic device of claim 1 , wherein light-emitting units of the first group of light-emitting units and light-emitting units of the second group of light-emitting units are all arranged in a triangular arrangement and the light-emitting units of the first group of light-emitting units and the light-emitting units of the second group of light-emitting units are shifted from each other.
