This invention is generally concerned with apparatus, methods and computer program code for driving electroluminescent displays, in particular organic light emitting diode (OLED) displays. A method of driving a passive matrix multicolour electroluminescent display, the display comprising a plurality of pixels arranged in rows and columns, each said pixel comprising at least first and second sub-pixels having different respective first and second colours, the method comprising: driving groups of said pixels in turn to display a multicolour image frame, said driving of a group of pixels comprising driving first and second sub-groups of sub-pixels of respective said first and second colours; and wherein said driving further comprises driving a said group of pixels for a duration dependent upon a maximum drive level of a sub-pixel of a said sub-group. The invention aims to provide an improved driving technique that mitigates the problems associated with the age effects of different coloured pixels. |
