Patent ID: 7986287

Claim:
A display device comprising: a battery; a pixel portion including a plurality of light-emitting elements; a source driver for driving the pixel portion; a timer circuit; a charging unit detection circuit; and a driving method selection circuit, wherein the timer circuit outputs a first signal for proceeding to a second burn-in correction period when a predetermined time passes after an end of a first burn-in correction period through a first normal driving period in which an image is displayed, wherein the charging unit detection circuit outputs a second signal for proceeding to the second burn-in correction period when the battery is charged, wherein the driving method selection circuit outputs a third signal for proceeding to the second burn-in correction period from the first normal driving period when the first signal and the second signal are inputted, and proceeding to a second normal driving period from the second burn-in correction period when the first signal and the second signal are not inputted, and wherein characteristics of the plurality of light-emitting elements are obtained by making the plurality of light-emitting elements emit light one by one in the first burn-in correction period, and by making light-emitting elements of red, blue and green emit light at a same time in the second burn-in correction period.
