Abstract:
A display system comprising a matrix of display pixels each comprising solid-state lamp means having different properties individual to the corresponding pixel, said display system comprising:storage means permanently storing for each of said lamp means individually physical information derived by measurement of at least one of the current of the lamp means and light generated by the lamp means;a plurality of transistors each operable to drive a corresponding one of the lamp means in a row of said matrix;a plurality of single-bit memory elements each of which controls an associated one of said plurality of transistors;a microprocessor for outputting for each of said memory elements a serial data stream that is loaded into the memory element, the serial data stream being dependent on the physical information of a lamp means that is driven under control of the memory element; andmeans for reducing differences in the appearances of said matrix pixels that are due to differences in the properties of the corresponding lamp means.
