Patent ID: 8471796

Claim:
A display device having gate lines and data lines comprising: a grayscale voltage provider that provides grayscale voltages using a first reference voltage and a second reference voltage in accordance with a selection signal; a data driver that applies data voltages to the data lines using the grayscale voltages and an image signal; a gate driver that successively provides a gate-on voltage to the gate lines; and a display panel that displays an image for each frame using the data voltages and the gate-on voltage, wherein the grayscale voltage provider comprises a reference voltage selector having a first node to which the first reference voltage is applied and a second node to which the second reference voltage is applied, wherein a stabilization capacitor is coupled to the first node such that the first node is chargeable at a lower rate than the second node, and wherein the grayscale voltage provider in response the selection signal outputs the second reference voltage as a reference voltage for a specified time after the display device is powered on based upon a capacitance of the stabilization capacitor, followed by the first reference voltage as the reference voltage after the specified time.
