Abstract: A display device includes a display panel, a temperature sensor that detects an ambient temperature and outputs a first temperature signal corresponding to the detected ambient temperature, a memory that receives a memory power supply voltage and stores a compensation signal, a driving controller that receives the first temperature signal from the temperature sensor and an input image signal, and provides the display panel with an output image signal which is obtained by compensating for the input image signal based on the compensation signal from the memory, and a voltage generator that generates the memory power supply voltage in response to a voltage control signal from the driving controller. The driving controller outputs the voltage control signal such that the memory power supply voltage has a voltage level corresponding to the first temperature signal.

Abstract: A display device includes a driving control circuit that receives an input image signal and outputs an output image signal, a data driving circuit that outputs a data signal corresponding to the output image signal, and a display panel including a plurality of pixels to display an image corresponding to the data signal. The driving control circuit determines an amount of time the input image signal is maintained as a still image, determines a color coordinate gain based on the amount of time and outputs the output image signal based on the color coordinate gain.
