Abstract:
A voltage generation circuit of a display device includes an over-current detection circuit that provides a driving voltage to a voltage terminal and outputs an over-current detection signal. The over-current detection circuit includes a current detector that outputs a detection signal at a first level when a voltage corresponding to an output current flowing through the voltage terminal during a blank period, in which a blank signal is activated, is lower than a first reference level or higher than a second reference level, a glitch remover that outputs a noise detection signal when a time period in which the detection signal is maintained at the first level is longer than a reference maintenance time, and a noise filter that activates the over-current detection signal when the noise detection signal is activated at least twice during a predetermined time period.

Claim (Index 17):
A display device comprising:\n a display panel comprising a plurality of gate lines, a plurality of data lines, and a plurality of pixels, each of which is connected to a corresponding gate line of the gate lines and a corresponding data line of the data lines; a gate driving circuit which drives the gate lines; a data driving circuit which drives the data lines; a driving controller which controls the gate driving circuit and the data driving circuit in response to a control signal and an image signal, which are provided thereto from an external source, and outputs a blank signal and a vertical start signal; and a voltage generation circuit which operates in synchronization with the blank signal and the vertical start signal, and generates a driving voltage to drive the gate driving circuit and the data driving circuit, wherein the voltage generation circuit comprising:\n a voltage terminal which outputs a driving voltage; \n a voltage generator which generates an internal driving voltage; and \n an over-current detection circuit which converts the internal driving voltage to the driving voltage to provide the driving voltage to the voltage terminal, detects an output current flowing through the voltage terminal during a blank period, in which the blank signal is activated, and outputs an over-current detection signal, \n wherein the over-current detection circuit comprising:\n a current detector which outputs a detection signal at a first level when a voltage corresponding to the output current is lower than a first reference level or higher than a second reference level; \n a glitch remover which outputs a noise detection signal when a time period, during which the detection signal is maintained at the first level, is longer than a reference maintenance time period; and \n a noise filter which activates the over-current detection signal when the noise detection signal is activated at least twice during a predetermined time period.
