Colour ratios in a 3d image display device
First Claim
1. A display device (101) for displaying a three dimensional image such that different views are displayed according to the viewing angle, the display device including:
- a display panel (15, 53) having a plurality of separately addressable pixels (0 . . . 10) for displaying said image, the pixels being grouped such that different pixels in a group (16) correspond to different views of the image;
a display driver (52) for controlling an optical characteristic of each pixel to generate an image according to received image data; and
a colour compensation device (60, 70) for further controlling said optical characteristic of at least some pixels within a group to compensate for a predetermined viewing angle dependency of said optical characteristic.

Abstract
A display device for displaying a three dimensional image such that different views are displayed according to the viewing angle has a display panel with a plurality of separately addressable pixels for displaying said image. The pixels are grouped such that different pixels in a group correspond to different views of the image. The pixels are configured in colour clusters for each physical location within the image, a cluster comprising three pixel groups each corresponding to a different primary colour. A display driver controls a transmission characteristic of each pixel to generate an image according to received image data. The drive signals applied to each pixel in the display panel are adjusted using colour correction values that vary the optical transmission of each pixel within a group and each group within a cluster so as to produce an image colour for each cluster that is independent of viewing direction.

18. A method for displaying a three dimensional image on a display device such that different views of the image are displayed according to the viewing angle, the method comprising the steps of:
-
processing image data to form pixel data values for each one of a plurality of separately addressable pixels (0 . . . 10) in display panel (15, 53), the pixels being grouped such that different pixels in a group (16) correspond to different views of the image, the pixel data values each for controlling an optical characteristic of a respective pixel to generate an image;
applying colour correction values to at least some pixel data values within each group to compensate for a predetermined viewing angle dependency of said optical characteristic; and
using said corrected pixel data values to drive pixels of a display panel to generate said image. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
