Abstract: A display apparatus including: gate lines extending in a first direction; data lines extending in a second direction intersecting the first direction; pixels connected to corresponding ones of the gate lines and data lines; a gate driver to drive the gate lines in response to a gate clock signal; a data driver to drive the data lines; a memory to store charge share signals corresponding to the gate lines; a timing controller controlling the data driver and the gate driver, in response to an externally input control signal and an image signal, and to output a gate pulse signal to the gate lines; and a clock generator configured to generate the gate clock signal in response to the gate pulse signal. The timing controller is configured to output the gate pulse signals according to the charge share signals.
