Abstract

In one embodiment of the invention, a stereophonic display device is provided. The stereophonic display device includes a pixel unit including a plurality of subpixels, wherein the subpixels include at least two right eye subpixels and two left eye subpixels, a barrier with a plurality of apertures formed on the pixel unit, wherein the smallest distance between the locations of the apertures projected onto the pixel unit and boundaries of the pixel unit is equal to or greater than a quarter of the width of the pixel unit, and a display image processor controlling the pixel unit rendering of the right eye subpixel block and the left eye subpixel block sequentially.

Claims

1. A stereophonic display device, comprising:

a pixel unit comprising a plurality of subpixels, wherein the subpixels comprise at least two right eye subpixels and two left eye subpixels;

a barrier with a plurality of apertures formed on the pixel unit, wherein the smallest distance between the locations of the apertures projected onto the pixel unit and boundaries of the pixel unit is equal to or greater than a quarter of the width of the pixel unit; and

a display image processor controlling the pixel unit rendering of the right eye subpixel block and the left eye subpixel block sequentially.

2. The stereophonic display device as claimed in claim 1, wherein the apertures are separated into at least two slit patterns.

3. The stereophonic display device as claimed in claim 1, wherein the apertures are combined.

4. The stereophonic display device as claimed in claim 1, wherein an optical distance in air between the pixel unit and the barrier is proportional to the number of subpixels.

5. The stereophonic display device as claimed in claim 1, wherein an optical distance in air between the pixel unit and the barrier and a width of one subpixel have a ratio of K, wherein K is greater than 9 and smaller than 15.

6. A stereophonic display device, comprising:

a pixel unit comprising a plurality of subpixels, wherein the subpixels comprise at least two right eye subpixels and two left eye subpixels;

a plurality of lenses formed on the pixel unit, wherein the smallest distance between the locations of the apexes of the lenses projected onto the pixel unit and boundaries of the pixel unit is greater than a quarter of the width of the pixel unit; and

a display image processor controlling the pixel unit rendering of the right eye subpixel block and the left eye subpixel block sequentially.

7. The stereophonic display device as claimed in claim 6, wherein the lenses are separated into at least two cylindrical lenses.

8. The stereophonic display device as claimed in claim 6, wherein the lenses are combined.

9. The stereophonic display device as claimed in claim 6, wherein an optical distance in air between the pixel unit and the apexes of the lenses is proportional to the number of subpixels.

10. The stereophonic display device as claimed in claim 6, wherein an optical distance in air between the pixel unit and the apexes of the lenses and a width of one subpixel have a ratio of K, wherein K is greater than 9 and smaller than 15.
