Abstract: A display device includes a display panel including a pixel, a temperature sensor which senses a temperature of the display panel and outputs the temperature of the display panel as a sensing temperature, a first compensation part which receives a gate-source voltage sensed in the pixel as a sensing voltage and compensates for the sensing voltage by a change amount of the gate-source voltage corresponding to a difference value between a reference temperature and the sensing temperature, and a second compensation part which compensates for data to be applied to the pixel by comparing a compensated sensing voltage with an initial gate-source voltage.

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.
