TIMING CONTROLLER OF DISPLAY DEVICE AND METHOD FOR DRIVING THE SAME

摘要

In a timing controller capable of decreasing flicker of an image to be displayed and a method of driving the same, the timing controller includes: a timing signal generator outputting a scan starting signal and clock signals to a scan driving unit; a sensing unit sensing status transition time points of the scan starting signal and the scan signal outputted from the scan driving unit for a plurality of frame periods; an estimator estimating a delay value and a jitter value with respect to the status transition time points; and an off-set signal generator generating an off-set signal for controlling the scan starting signal or the clock signals based on the delay value and the jitter value. The timing signal generator, in response to the off-set signal, regulates timings of the scan starting signal and the clock signals.
