Abstract: An electronic device is disclosed that includes a display panel, a data driving circuit, a scan driving circuit, and a driving controller. The driving controller generates image data based on a received image signal. The driving controller includes a minimum emission gray level determining unit that determines a gray level of the image signal, a pattern determining unit that determines a dither pattern of the image signal, a driving frequency sensing unit that determines a driving frequency of the image signal, and a data compensation unit that compensates for the image data based on the gray level and at least one of the dither pattern and the driving frequency.

Abstract: A display device is disclosed that includes a display panel which includes a pixel, a driving controller which receives an input image signal and outputs an output image signal, and a data driving circuit which provides a data signal corresponding to the output image signal to the pixel. The pixel includes a light emitting device and a first transistor electrically connected to the light emitting device. The driving controller includes an initial threshold voltage map that stores an initial threshold voltage of the first transistor, a delta threshold voltage calculator that calculates a delta threshold voltage of the first transistor over an operating time based on the initial threshold voltage, a weight calculator that calculates a weight based on the initial threshold voltage and the delta threshold voltage, and a compensator that receives the input image signal and outputs an output image signal obtained by compensating for a threshold voltage of the first transistor based on the weight.
