Abstract: A display device includes pixels connected to scan lines, sensing lines, readout lines, and data lines; a scan driver including stages to supply a scan signal and a sensing signal to the scan lines and the sensing lines; a data driver which supplies a data signal to the data lines; a timing controller which divides one frame into an active period including a scan period in which the data signal is supplied to the data lines and a display period in which the pixels emit light in response to the data signal, and a blank period including a sensing period in which electrical characteristics of the pixels are detected and a reset period in which the stages are reset; and a compensator which generates a compensation value for compensating for deterioration of the pixels based on sensing values provided from the readout lines during the sensing period.

Abstract: A display device includes a display panel including: a plurality of pixels; and a signal controller which generates, on a frame-by-frame basis, a display signal based on an input image signal and a control signal from an outside. The signal controller includes a memory which stores a preset image signal, a receiver which receives the control signal, a clock signal modulator which generates an internal clock signal having a first frequency during a blank period, which is determined based on the control signal in a frame period, and a data processor which reads the preset image signal from the memory in response to the internal clock signal for an image processing.
