ABSTRACT:
A display device includes a self light-emitting display in which data electrodes and scanning electrodes are arranged in matrix form, and a modulating voltage is applied to the data electrode side while a threshold voltage is applied to the scanning electrode side, the device including: a signal level range determination means for digitally processing an input signal to determine a signal level range of the input signal for every prescribed frame number unit; a threshold voltage control means for controlling a threshold voltage based upon a determination result by the signal level range determination means; and an input signal correction means for correcting an input signal level based upon a determination result by the signal level range determination means.
