Abstract
According to an aspect of the present disclosure, a gate driver includes a plurality of stages which is dependently connected to each other and each of the plurality of pixels includes: a first output unit which outputs a sensing signal by voltages of a Q node and a QB node; a second output unit which outputs a reference signal by the voltages of the Q node and the QB node; a third output unit which outputs a scan signal by the voltages of the Q node and the QB node; a first controller which controls the Q node; and a second controller which controls the QB node, and at least two of the first to third output units share at least one clock signal among a plurality of clock signals, thereby reducing an area of the gate driver.
