    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 odd-numbered and even-numbered gate lines in a first direction, a plurality of data lines in a second direction, a plurality of pixels, a data and gate driver, and a timing controller. The pixels in a column extending in the second direction are alternatingly connected to a first data line located left of the column and a second data line located right of the column, among the plurality of data lines. The timing controller controls the gate driver and the data driver to sequentially apply a first image and a black image to the pixels connected to the odd-numbered gate lines during a first interval to display the first image on the display panel and sequentially apply a second image and the black image to the pixels connected to the even-numbered gate lines during a second interval to display the second image on the display panel.
