A display system and its driving method is provided. The system includes: a driver for operating a panel having a plurality of pixels arranged by a plurality of first lines and at least one second line, the driver including: a driver output unit for providing to the panel a single driver output for activating the plurality of first lines, the single driver output being demultiplexed on the panel to activate each first line. The system includes: a driver for operating a panel having a plurality of pixels arranged by a plurality of data lines and at least one scan line, the driver including: a shift register unit including a plurality of shift registers; a latch and shift register unit including a plurality of latch and shift circuits for the plurality of shift registers, each storing an image signal from the corresponding shift register or shifting the image signal to a next latch and shift circuit; and a decoder unit including at least one decoder coupled to one of the latch and shift circuits, for decoding the image signal latched in the one of the latch and shift circuit to provide a driver output. The system includes: a driver for operating a panel having a plurality of pixels, the driver including: a plurality of multiplexers for a plurality of offset gamma curve sections, each offset gamma curve section having a first range less than a second range of a main gamma curve, at least one of offset gamma curve sections being offset by a predetermined voltage from a corresponding section of the main gamma curve; a plurality of decoders for the plurality of multiplexers; and an output buffer for providing a driver output based on the output from the decoder and the predetermined voltage.
