Level shifter for simultaneous reset and sensing line selection, display apparatus including the same, and driving method thereof

A method of driving a display device including a gate driver configured to provide a gate signal to pixels, a timing controller configured to control an operation of the gate driver, and a level shifter configured to provide a clock signal to the gate driver based on a clock control signal input from the timing controller, the method comprising:

• a reset and line selection operation of initializing the gate driver in response to a reset signal provided from the level shifter to the gate driver and selecting a pixel line to be sensed based on a number of pulses of the clock control signal applied to the level shifter from the timing controller for a blank time within a frame;
• and
• a sensing operation of applying, by the gate driver, the gate signal to the selected pixel line to sense characteristics of pixels on the selected pixel line based on the clock signal provided from the level shifter to the gate driver, in response to the reset signal transitioning to a turn-off level.
