Classification: CPC G  H | IPC G

Claim 15:
16. A method of driving a display device, comprising:
determining digital video data corresponding to a low gray level region among digital video data;
outputting modulated digital data by increasing a value of the digital video data of the low gray level region;
outputting a pulse-width modulation (PAM) control signal corresponding to the low gray level region as a first level voltage and outputting the pulse-width modulation (PAM) control signal corresponding to a high gray level region other than the low gray level region as a second level voltage;
generating PWM data voltages according to the modulated digital video data and outputting the PWM data voltages to PWM data lines; and
outputting PAM data voltages to PAM data lines according to the PAM control signal.
