Abstract
A gate driver circuit includes a gate driver coupled to a gate line. The gate driver generates a gate signal for input to a plurality of pixels and controls a current of the gate signal based on an IR-drop of a supply voltage supplied to the pixels through a supply voltage distribution line. The gate driver decreases the current of the gate signal when the IR-drop increases, and increases the current of the first gate signal when the IR-drop decreases. A pulse width of an activation period of the gate signal decreases and luminance of the pixels increases when the current of the first row pixels decreases.
