Abstract
Systems for providing driving voltage of display panels. An exemplary system comprises a data driving circuit with a plurality of driving units generating analog voltage to drive corresponding pixels according to digital data signals from a data bus, each comprising a temporary storage unit storing N digital data in sequence according to N control signals in a first period and outputting the N digital data in sequence according to M switching signals in a second period; a digital-to-analog (DA) conversion unit converting the N digital data to N analog voltages in sequence; an analog buffering unit buffering the N analog voltages from the DA conversion unit; and a de-multiplexer outputting the N analog voltages to the corresponding pixels selectively according to an enabling signal.
