Abstract: The present invention relates to a method of driving a display comprising: receiving grey level input data, comprising a subpixel input data consisting of N bits, from an external image data source; mapping the L upper bits of the N-bit subpixel input data to an L-bit first mapped data, where L≦̸(N−1); generating an additional bit of mapped data; using the lower N-L bits of said N-bit subpixel input data for a control operation; including providing a driver data consisting of L+1 bits, based on the first mapped data and the additional bit of mapped data, to a driver circuit; and controlling the driver circuit to output driving voltages set in relation to the driver data, to a display element, wherein the total number of voltage levels correspond to the maximum value representable by the L bits, plus one. The control operation further comprises, performing frame mixing comprising providing said driver data as either representing said first mapped data or an increment thereof. The additional bit is, inter alia, used to enable representation of said increment.
