Electronic system for tiled displays

1. A tiled display, comprising:

a) a display controller for receiving image data for images of different sizes from an image data source and formatting the image data for display;

b) a plurality of display tiles, each display tile having an array of display pixels, a tile controller, a clock, a memory and a communication interface, wherein the tile controllers are each programmed to compute a portion of the images of different sizes to be stored in the associated tile memory; and

c) the display tiles being serially connected through the communication interfaces, with one display tile being connected to the display controller, the display controller sending image data to the one display tile for an image to be displayed on the serially connected display tiles, and each display tile successively storing the portion of image data to be displayed on its array of display pixels and transmitting only remaining image data to the next display tile in the series.

2. The tiled display claimed in claim 1 , wherein the tiled display comprises a two dimensional array of display tiles connected in series.

3. The tiled display claimed in claim 1 , wherein the display controller incorporates a display tile that acts as the first display tile in the series.

4. The tiled display claimed in claim 1 , wherein the display pixels are OLEDs.

5. The tiled display claimed in claim 1 , wherein the display tiles are identical.

6. The tiled display claimed in claim 1 , wherein the tiled display has an aspect ratio and the tile controllers include means for adapting image data formatted by the display controller having an aspect ratio different from the aspect ratio of the tiled display.

7. The tiled display claimed in claim 1 , wherein the tile controllers include means for changing the resolution of the image data formatted by the display controller.

8. The tiled display claimed in claim 1 , wherein the tile controllers include means for calculating the time for image data distribution to all of the display tiles in the display and for displaying the image data after all of the display tiles have received the image data.

9. The tiled display claimed in claim 1 , wherein the tile controllers include means for determining their locations in the tiled display and storing in respective memories a portion of the image data corresponding to their locations in the tiled display.

10. A tiled display, comprising:

a) a display controller for receiving image data for images of different sizes from an image data source and formatting the image data for display;

b) a plurality of display tiles, each display tile having an array of display pixels, a tile controller, a clock, a memory and a communication interface, wherein the tile controllers are each programmed to compute a portion of the images of different sizes to be stored in the associated tile memory; and

c) the display tiles being serially connected through the communication interfaces, with one display tile being connected to the display controller, the display controller sending image data to the one display tile for an image to be displayed on the serially connected display tiles, and each display tile successively storing the portion of image data to be displayed on its array of display pixels and transmitting any remaining image data to the next display tile in the series; further comprising a plurality of linear arrays, each linear array comprising a display controller and serially connected display tiles, and wherein the display controllers of the plurality of linear arrays are connected in series and one of the display controllers receives image data from the image data source.
