Abstract

A three-dimensional (3D) image display device and a method thereof are provided. A first light filtering unit obtains a first RGB color light filtered from a first image, and a second light filtering unit obtains a second RGB color light filtered from a second image, to produce a left-eye image and a right-eye image, respectively, or an active light emitting panel produces a first image and a second image of different wavelengths. When a user is wearing glasses with different light filters on the left and right lenses to filter out the right-eye image and the left-eye image, respectively, the user receives 3D visual effects from the images.

Claims

1. A three-dimensional image display device, comprising:

a light source module for producing an image light source;

a liquid crystal display module for producing an image from the image light source, the liquid crystal display module being provided with a first light filtering unit that filters a first RGB color light to allow the light crystal display module to produce a left-eye image, and a second light filtering unit that filters a second RGB color light to allow the liquid crystal display module to produce a right-eye image, the first RGB color light having a first wavelength different from a second wavelength of the second RGB color light;

a left lens having a third light filtering unit that filters the right-eye image; and

a right lens having a fourth light filtering unit that filters the left-eye image.

2. The three-dimensional image display device of claim 1, wherein the light source module includes a first backlight source incorporated with the first light filtering unit for producing a first image light source and a second backlight source incorporated with the second light filtering unit for producing a second image light source, the image light source is composed of the first image light source and the second image light source.

3. The three-dimensional image display device of claim 2, wherein the liquid crystal display module time-interleaving the filtered first image light source and the filtered second image light source to produce the left-eye image and the right-eye image, respectively.

4. The three-dimensional image display device of claim 1, wherein the liquid crystal display module has a first surface facing a user and a second surface facing the light source module, and the first light filtering unit and the second light filtering unit are disposed on the first surface or on the second surface at the same time.

5. The three-dimensional image display device of claim 4, wherein the first light filtering unit and the second light filtering unit are alternately arranged on the first surface or on the second surface, or the first light filtering unit and the second light filtering unit are alternately provided to form a light filter that is provided on the first surface or on the second surface.

6. A three-dimensional image display device, comprising:

an active light emitting panel including a first pixel module for producing a first light source of a first RGB color light and a second pixel module for producing a second light source of a second RGB color light, and producing from the first pixel module a first image and from the second pixel module a second image having a second wavelength different from a first wavelength of the first image, the first pixel module and the second pixel module being alternately arranged on the active light emitting panel and producing the first image and the second image in a time-interleaving manner;

a left lens having a first light filtering unit that filters the second image; and

a right lens having a second light filtering unit that filters the first image.

7. A three-dimensional image display device, comprising:

an active light emitting panel including a first light filtering unit that obtains a first RGB color light and a second light filtering unit alternately arranged with respect to the first light filtering unit that obtains a second RGB color light, and producing from the first light filtering unit a first image and from the second light filtering unit a second image having a second wavelength different from a first wavelength of the first image;

a left lens having a third light filtering unit that filters the second image; and

a right lens having a fourth light filtering unit that filters the first image.

8. The three-dimensional image display device of claim 7, wherein the first light filtering unit and the second light filtering unit are alternately arranged on the active light emitting panel, or alternately arranged to form a light filter that is provided on the active light emitting panel.
