Abstract: The present disclosure provides a gate clock generator including a counter, a buffer control signal generator, and an output unit. The counter receives control data having rising timing information and falling timing information and a main clock. The counter generates a first output when a value is obtained by counting the main clock from a preset reference time point reaches rising data. The counter further generates a second output when a value is obtained by counting the main clock from the reference time point reaches falling data. The buffer control signal generator generates a first buffer control signal of a gate ON voltage from a timing of the first output to a timing of the second output. The output unit outputs a gate ON voltage of a gate clock during an output period of the gate ON voltage of the first buffer control signal.

Abstract: Provided is a display device including a level shifter generating an output clock swinging between a first voltage and a third voltage during a display period and swinging between a second voltage and the third voltage during a touch sensing period. Waveform distortion of a no-load alternating current (AC) signal may be prevented without eliminating a stabilizing capacitor of the level shifter, and thus, sensing sensitivity may be increased by reducing noise of a touch sensor signal.

Abstract: Embodiments of the present disclosure relate to a level shifter and a display device capable of differently controlling a signal waveform between a first clock signal and a second clock signal used to output a first gate signal and a second gate signal. Accordingly, it is possible to reduce the variation in output characteristics between the first gate signal and the second gate signal, thereby improving image quality.

Abstract: A power supply and a display device using the same are provided. The power supply includes a logic voltage generator and a power voltage generator. The logic voltage generator generates an internal logic voltage based on an externally input voltage. The power voltage generator generates a plurality of power voltages based on the external input voltage. When the external input voltage is cut off, the power voltage generator stops outputting a drain voltage, and then stops outputting a half drain voltage.
