TILED ELECTRONIC DISPLAY STRUCTURE

摘要

PROBLEM TO BE SOLVED: To eliminate the visibility of the seams between tiles and ensure electrical access to pixels.

SOLUTION: A tiled display device 100 is formed from display tiles 120 including pixel positions. A pixel area has an organic light-emitting diode (OLED) active area. Each tile includes a memory, and pixel driving circuitry located on the back side of the tile. Connections to pixel electrodes on the front side of the tile are made by vias which pass through non-selected portions of the pixel areas which are not occupied by the active pixel material. The tiles are formed by an electronics section and a display section. Each of these parts includes connecting pads which cover several pixel positions, and each connecting pad makes an electrical connection to only one row electrode or column electrode. Each tile has a glass substrate on the front of the tile. Black matrix lines are formed all over the glass substrate and the tiles are joined by mullions which have the same appearance as the black matrix lines.
