Abstract:
Digital driving circuitry for driving an active matrix display comprising a plurality of pixels logically organized in a plurality of rows and a plurality of columns, each pixel comprising a light emitting element, comprises a current driver for each of the plurality of columns for driving a predetermined current through the corresponding column, the predetermined current being proportional to the number of pixels that are ON in that column. The digital driving circuitry further comprises digital select line driving circuitry for sequentially selecting the plurality of rows, and digital data line driving circuitry for writing digital image codes to the pixels in a selected row, synchronized with the digital select line driving circuitry.
