  • Patent number: 8159512
    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.
