Abstract
A method of driving a display device includes: sensing characteristic information of pixels by outputting sensing voltages to sensing lines; and operating an external compensation of the pixels based on the characteristic information. The sensing of the characteristic information of pixels includes: detecting a capacitance deviation of sensing capacitors of first sensing lines connected to the sensing lines; and sensing the characteristic information of the pixels by replacing at least one of the first sensing lines with a second sensing line based on the capacitance deviation.
