Abstract

This invention relates to methods and apparatus for driving emissive, in particular organic light emitting diodes (OLED) displays using multi-line addressing (MLA) techniques. Embodiments of the invention are particularly suitable for use with so-called passive matrix OLED displays. A method of driving an emissive display, the display comprising a plurality of pixels each addressable by a row electrode and a column electrode, the method comprising: driving a plurality of said column electrodes with a first set of column drive signals; and driving two or more of said row electrodes with a first set of forward bias row drive signals at the same time as said column electrode driving with said column drive signals; then driving said plurality of column electrodes with a second and subsequent sets of column drive signals; and driving said two or more row electrodes with a second and subsequent sets of forward bias row drive signals at the same time as said column electrode driving with said second column drive signals.
