    Abstract: An image display system includes a graphic processor which generates an image signal, a control signal, and a variable frequency signal; and a display device which displays an image at a frame frequency corresponding to the variable frequency signal from the graphic processor. The display device includes pixels connected to emission control lines, data lines, and scan lines; a controller which provides reference data including information on reference cycles, which are cycles in which an emission control start signal is output, to the graphic processor, outputs the emission control start signal based on the control signal, and adjusting an output timing of a scan start signal based on the variable frequency signal; an emission driver which supplies emission control signals to the emission control lines based on the emission control start signal; and a scan driver which supplies scan signals to the scan lines based on the scan start signal.

    Abstract: Disclosed is a display device that can rapidly recover from a fail situation. The display device includes: a display panel; a source drive IC configured to supply a data signal to the display panel and including a calibrating unit; a timing controller configured to supply a data control signal and a frame data to the source drive IC; and a common bus line formed between the source drive IC and the timing controller. The calibrating unit sets and stores a calibration value in response to the data control signal during an initialization period before receiving the frame data from the timing controller, and transmits the calibration value to the timing controller through the common bus line.
