Abstract
A display device includes an N-phase level shifter configured to receive an output cancellation signal, a first reference signal, and a second reference signal from a timing controller, and to output N sensing clock signals to a gate driver, and the gate driver configured to receive the N sensing clock signals from the N-phase level shifter, and to output N sensing output signals to first to n-th gate lines, wherein the N-phase level shifter is configured to receive the output cancellation signal having a number of pulses during a blank period, and the a is at least two.
Claims15
A display device comprising:
- an N-phase level shifter configured to:
- receive an output cancellation signal, a first reference signal, and a second reference signal from a timing controller,
- count a number of pulses in at least one of the first reference signal and the second reference signal, and
- output a plurality of sensing clock signals to a gate driver based on inhibiting output of a number of clock signals corresponding to the number of pulses;
- and
- wherein the gate driver is configured to receive the plurality of sensing clock signals from the N-phase level shifter and to output a plurality of sensing output signals to first to n-th gate lines,
- wherein the N-phase level shifter is configured to inhibit output of a portion of the sensing clock signals of the plurality of sensing clock signals based on the number of pulses.
