    摘要： First and second bits of pixel values of the display are received, and each of the first and second bits is forwarded through one of data signals. Then, levels of the data signals are shifted, and the forwarded first and second bits are received through the level-shifted data signals to convert the pixel values into analog voltages driving the display. The level-shifted data signals through which the forwarded first and second bits are received are generated in a first and second phase, respectively.

    摘要： In a pixel array, each column of the pixel array is coupled to one of a plurality of first and second channels of a driver. A first and second control signals are generated. Polarities of the first channels are inversed when a logic level of the first control signal changes and polarities of the second channels are inversed when a logic level of the second control signal changes. Only the logic level of one of the first and second control signals changes in response to each transition of scan periods.
