Abstract

A method for extending grey scale capabilities of a display (104) is disclosed. The display (104) is divided into a plurality of blocks (126), each block (126) being driven by a corresponding column driver (124). In dependence on a brightness level of a part of a received image (120) to be displayed on a corresponding block (126), a supply voltage (Vdd) is generated for a column driver (124) for the corresponding block (126). The level of the supply voltage (Vdd) depends on the brightness level of each block (126). The present invention has the advantage over the prior art that it expands the grey scale capabilities of a display (104) without needing to extend the capabilities of the column drivers (124).
