Patent ID: 7250888

Claim:
A system for displaying images, comprising: a data driving circuit, comprising a plurality of driving units being operative to generate analog voltage, to drive corresponding pixels according to data signals from a data bus, each driving unit comprising: a temporary storage unit, operative to store N first 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; 2N sets of latches connected in series; 2N sets of switching elements coupled between each two sets of latches and between the latches and the data bus respectively; a digital-to-analog (DA) conversion unit, coupled to the temporary storage unit, and operative to convert the N first digital data to N analog voltages in sequence; an analog buffering unit, operative to buffer the N analog voltages from the DA conversion unit; and a de-multiplexer, operative to selectively output the N analog voltages to the corresponding pixels according to an enabling signal.
