Claim:
1. A method of reducing power consumption in a display device comprising a display panel and a set controller, the method comprising: operating the set controller in a normal driving mode to display an image on the display panel, by outputting a clock signal and an image data signal; operating the set controller in a sleep mode when a sleep mode command is received, by adjusting the clock signal and the image data signal to a first voltage; measuring a sleep mode time period during which the controller operates in the sleep mode; and operating the set controller in a clock-off mode when the measured sleep mode time period exceeds a first reference time period, by adjusting the clock signal to a second voltage, while maintaining the image data signal at the first voltage, wherein the second voltage is lower than the first voltage, and the second voltage is applied to a clock lane in the clock-off mode.
