Abstract

A 3D/2D multi-primary color image device is provided with an optical unit to direct a first image to a first group of viewers and a second image to a second group of viewers. Each color dot of the multi-primary color image device comprises at least two color sections controlled independently. A first group of viewers and a second group of viewers can view simultaneously and respectively a first image and a second image.

Claims

1. An image device, comprising:

a plurality of pixel groups, each of the pixel groups comprising;

a plurality dots arranged in a predetermined identical matrix form, each of the pixel groups having at least one first color dot, at least one second color dot, at least one third color dot and at least one fourth color dot,

wherein the first color dot comprises at least two first color sections controlled independently, and the second color dot comprises at least two second color sections controlled independently, the third color dot comprises at least two third color sections controlled independently, and the fourth color dot comprises at least two fourth color sections controlled independently,

wherein depending on an orientation of the image display with respect to a viewer, one of the at least two first color sections of each of the pixel groups is located directly between another of the at least two first color sections and one of the at least two third color sections, in a row direction or a column direction and

the data inputted to one of the at least two color sections of each color dot is multiprimary color signals for a first group of viewers, and the data inputted to another one of the at least two color sections of each color dot is multiprimary color signals for a second group of viewers.

2. The image device according to claim 1, further comprising an optical unit disposed at one side of the image device and having view-separation elements arranged in the first direction into multiple rows and columns.

3. The image device according to claim 2, wherein the optical unit is a liquid crystal shutter.

4. The image device according to claim 2, wherein the optical unit is a lenticular lens.

5. The image device according to claim 2, wherein the optical unit is a parallax barrier.

6. The image device according to claim 1, further comprising a first sub-pixel rendering and color space converting device for receiving input data for a first image in a first color space and outputting multi-primary color section signals for the first image in a second color space.

7. The image device according to claim 6, further comprising a second sub-pixel rendering and color space converting device for receiving input data for a second image in the first color space and outputting multi-primary color section signals for the second image in the second color space.

8. The image device according to claim 1, wherein the two first color sections are arranged in a first direction, the two second color sections are arranged in the first direction, the two third color sections are arranged in the first direction, the two fourth color sections are arranged in the first direction.

9. The image device according to claim 1, wherein the two first color sections are arranged in a second direction, the two second color sections are arranged in the second direction, the two third color sections are arranged in the second direction, the two fourth color sections are arranged in the second direction.

10. The image device according to claim 1, wherein each of the color dots represents a luminance and a chrominance of a corresponding full color pixel data by grouping with neighboring dots to form a plurality of overlapping full color dynamic pixel groups.

11. The image device according to claim 1, wherein the second color dot and the third color dot have lower light intensity than the first color dot and the fourth color dot in a white balance status, and

the first color dot and the fourth color dot are disposed on diagonal positions of the predetermined identical matrix in each of the pixel groups.

12. The image device according to claim 11, wherein the first color dot, the second color dot, the third color dot and the fourth color dot are quadrate shaped.

13. The image device according to claim 11, wherein the first color dot, the second color dot, the third color dot and the fourth color dot are rectangular shaped.

14. The image device according to claim 11, wherein the first color dot is a green dot, the second color dot is a blue dot, the third color dot is a red dot and the fourth color dot is a white dot.

15. The image device according to claim 11, wherein two of the color dots are small color dots, two of the color dots are big color dots, so that an area of each of the two small color dots is smaller than that of each of the two big color dots.

16. The image device according to claim 15, wherein the area of the first color dot is equal to that of the fourth color dot, the area of the third color dot is equal to that of the second color dot, and

the area of the first color dot is smaller than that of the third color dot.

17. The image device according to claim 16, wherein a sum of the two areas of the two small color dots is equal to the area of one of the big color dots.

18. The image device according to claim 17, wherein the first color dot is a green dot, the second color dot is a blue dot, the third color dot is a red dot and the fourth color dot is a green dot.

19. A method for controlling the image device as claimed in claim 1, comprising the steps of:

(a) first sub-pixel rendering and color space converting the input data for a first image in a first color space, and outputting multi-primary color section signals for the first image in the second color space; and

(b) second sub-pixel rendering and color space converting the input data for a second image in the first color space and outputting multi-primary color section signals for the second image in the second color space.

20. An image device, comprising:

a plurality of pixel groups, each of the pixel groups comprising;

a plurality dots arranged in a predetermined identical matrix form, each of the pixel groups having at least one first color dot, at least one second color dot, at least one third color dot and at least one fourth color dot,

wherein the first color dot comprises at least two first color sections controlled independently, and the second color dot comprises at least two second color sections controlled independently, the third color dot comprises at least two third color sections controlled independently, and the fourth color dot comprises at least two fourth color sections controlled independently,

wherein depending on an orientation of the image display with respect to a viewer, one of the at least two first color sections of each of the pixel groups is located directly between another of the at least two first color sections and one of the at least two third color sections, and

the first color dot and the second color dot in first pixel groups and the first color dot and the second color dot in second pixel groups are arranged alternately, in a row direction or a column direction.
