Patent ID: 7982729

Claim:
A driving signal generating device for staggering transition time of driving signals to prevent image crosstalk for a display device, the driving signal generating device comprising: a receiving terminal for receiving a plurality of step grayscale waveforms; a first adjusting unit coupled to the receiving terminal, for transforming the plurality of step grayscale waveforms into a plurality of initial grayscale waveforms according to a first control signal and adjusting widths of the plurality of initial grayscale waveforms according to a first predetermined value to generate a plurality of grayscale waveforms, where the plurality of the initial grayscale waveforms corresponds to a plurality of grayscale values of the display device; a multiplexer coupled to the first adjusting unit, for selecting a first grayscale waveform from the plurality of grayscale waveforms according to a second control signal; a second adjusting unit coupled to the multiplexer, for adjusting a width of the first grayscale waveform according to a second predetermined value to generate a second grayscale waveform; and a frame output controller coupled to the second adjusting unit and the multiplexer, for controlling output of the first grayscale waveform and the second grayscale waveform.
