DISPLAY DEVICE AND DRIVE METHOD THEREOF

摘要

A display device making it possible to prevent burn-in by suppressing the occurrence of VCOM shifts occurring when the liquid crystal panel has been driven over a long period of time, and a drive method thereof are provided. Because the source output voltage corresponding to the gradation levels from gradation 0 to gradation 224 coincides with a flicker adjustment voltage, the amount of shift from the flicker adjustment voltage is 0mV; the source output voltage corresponding to gradation 255 is obtained by adding +40mV, as the shift amount, to 4.05V, the flicker adjustment voltage. In this way, the source output voltage, which is increased at high gradation levels and in the vicinity thereof, is applied to source lines (SL1-SLm) and written to the liquid crystal capacitors (Ccl).
