Abstract: A display apparatus includes a display panel, a data driving circuit, and a gate driving circuit. The display panel is configured to display an image and includes a gate line and a data line. The data driving circuit is configured to output a data signal to the data line. The gate driving circuit is configured to output a gate signal to the gate line and to control a kick-back time of the gate signal according to a temperature of the display panel. The kick-back time is a time when the gate signal is decreased from a gate on voltage to a kick-back voltage that is between the gate on voltage and a gate off voltage.

Abstract: A display device includes a controller, a panel driver, and a voltage generator. The controller generates a first control signal and generates image data and a second control signal in response to first and second image signals. The panel driver generates a driving signal in response to the image data and the first control signal to drive a display panel. The voltage generator generates a driving voltage to drive the display panel and changes a voltage level of the driving voltage in response to the second control signal. The first image signal corresponds to a second frame located before a third frame in which the driving voltage is changed. The second image signal corresponds to a first frame located before the second frame. The controller generates image data corresponding to the second frame in response to the first image signal and the second image signal.
