Abstract:
1. A driver of a field sequential display, comprising: a first power device, for generating a first power when the field sequential display is in a color mode; a second power device, for generating a second power when the field sequential display is in a monochrome mode, wherein a voltage and a current of the second power are smaller than a voltage and a current of the first power, wherein the first power device is enabled when the field sequential display is in the color mode, and the second power device is enabled when the field sequential display is in the monochrome mode, according to a control signal; a driving waveform generator, coupled to the first power device and the second power device, for generating a plurality of scan signals and a plurality of display signals according to the first power or the second power, so as to drive a display panel of the field sequential display; and a control unit, wherein when the field sequential display is in the color mode and the control unit does not receive an input signal after a first period of time, the control unit switches the field sequential display into the monochrome mode and generates the control signal to enable the second power device, when the field sequential display is in the monochrome mode and the control unit does not receive the input signal after a second period of time, the control unit turns off the field sequential display and generates the control signal to disable the first power device and the second power device, and when the control unit receives the input signal, the control unit switches the field sequential display into the color mode and generates the control signal to enable the first power device.
