Abstract

A multiple view display comprises a display device such as an LCD and a parallax generating device such as a parallax barrier. The LCD and the barrier cooperate to form viewing regions for viewing a stereoscopic pair of views or for different viewers to see unrelated views from the same display. The display device comprises composite pixel groups, each of which comprises red, green and blue pixels with at least two pixels of the same colour and receiving the same image data. The pixels of the same colour may be connected together to receive the same image data or may be supplied with the same image data by a controller.

Claims

1. A multiple view display for displaying N views, where N is an integer greater than one, comprising:

a display device comprising a plurality of composite pixel groups, each of which comprises pixels of at least three different colours with at least two of said pixels of a same colour;

a parallax generating device cooperating with said display device to define a plurality of viewing regions; and

means for supplying said at least two pixels of said same colour of each said group with a same image data.

2. A display as claimed in claim 1, in which said at least three different colours comprise three different colours.

3. A display as claimed in claim 2, in which said three different colours comprise red, green and blue.

4. A display as claimed in claim 1, in which said pixels are arranged as sets of N columns with each said set cooperating with a respective parallax element of said parallax device.

5. A display as claimed in claim 4, in which each said group comprises four said pixels and said at least two pixels of said same colour comprise two said pixels.

6. A display as claimed in claim 5, in which said groups are arranged as rows with said two pixels of said same colour being said same colour in each said row.

7. A display as claimed in claim 6, in which said two pixels of said same colour are said same colour in all of said rows.

8. A display as claimed in claim 5, in which said pixels of each said group are arranged as two pairs of different coloured said pixels in a pair of said columns separated by (N−

1) of said columns.

9. A display as claimed in claim 5, in which said two pixels of said same colour have a smaller area than others of said pixels of each said group.

10. A display as claimed in claim 4, in which said three different colours comprise red, green and blue and in which each said group of said pixels comprises a pair of triplets of said red, green and blue pixels with said triplets in a pair of said columns separated by (N−

1) of said columns.

11. A display as claimed in claim 4, in which said three different colours comprise red, green and blue and in which each said group of said pixels comprises a pair of triplets of said red, green and blue pixels arranged in a row with adjacent pairs of said pixels of each said group being separated by (N−

1) of said columns.

12. A display as claimed in claim 1, in which said supplying means comprises a controller for supplying image data including said same image data to said display device.

13. A display as claimed in claim 1, in which said supplying means comprises a respective permanent connection between said at least two pixels of said same colour of each said group.

14. A display as claimed in claim 4, in which said supplying means comprises a switching arrangement for switching between a multiple view mode of operation, in which said at least two pixels of said same colour of each said group are connected together, and a one view mode of operation, in which each of said at least two pixels of said same colour of each said group is connected to another of said pixels of said same colour of a different one of said groups in an adjacent one of said columns.

15. A display as claimed in claim 1, in which said pixels of each said group have areas such that each said group is colour-balanced to white when each said pixel is at a maximum intensity.

16. A display as claimed in claim 1, in which said views are stereoscopically related.

17. A display as claimed in claim 1, in which said views are unrelated to each other.

18. A display as claimed in claim 1, in which N is equal to two.

19. A display as claimed in claim 1, in which said display device is a liquid crystal device.

20. A display as claimed in claim 1, in which said parallax device is a parallax barrier.
