<p>A video display unit consisting of a number of display units or modules arranged in a 2-D array which is fed with video signals from an interface unit connected to a convenient point on the array. Each unit preferably comprises a tile-shaped LCD module, enabling the display to be mounted on the wall, and includes its own control circuit on its rear surfaces. Since each unit takes part in decoding the video signals, an extremely versatile display can be realised, in which the overall size and/or aspect ratio may be changed by simply adding units to, or removing units from, the array. To enable interconnection, each unit has a recess lined with contacts at each edge, in a manner similar to a PCB edge connector, and contacts at the adjacent edges of adjacent units are connected by a coupling member. This interconnection arrangement removes the need for complex connections by means of a backplane. Each control circuit adapts its decoding system according to the size of the array and the position of the respective display unit within it, so that video signals which would otherwise be incompatible with the overall pixel array dimension of the display can be successfully decoded.</p> |
