Abstract
A display device includes a display panel including a gate line, a data line, a gate driver outputting a gate signal to the gate line, a data driver outputting a data voltage to the data line and a power voltage generator. The power voltage generator generates a gate-on voltage, a gate-off voltage, and a gate clock signal toggled between the gate-on voltage and the gate-off voltage, detects a current level of a gate clock current, cuts off power of the display device when a count of the gate clock current higher than or equal to a first current level is greater than or equal to a reference count, and cuts off the power of the display device when the gate clock current is higher than or equal to a second current level higher than the first current level in an initial frame after the display device is turned on.
