Display device and a method of driving a gate driver

Abstract

A display device includes: a display panel including data lines, gate lines, and pixels, the display panel is operated in an active period or in a blank period; and a driving circuit for driving the display panel, the driving circuit including: a signal controller for outputting clock control signals; a voltage generator for receiving the clock control signals, wherein the voltage generator outputs active clock signals synchronized with the clock control signals during the active period and outputs blank clock signals during the blank period; and an overcurrent detection circuit for receiving the clock control signals and the blank clock signals, the overcurrent detection circuit detects an overcurrent of the blank clock signals, and a phase difference between the clock control signals in the active period is different from a phase difference between the clock control signals in the blank period.
