Abstract:
1. A self-luminescent display device comprising: a pixel unit in which a plurality of pixels including a self-luminescent pixel is arranged; an external light sensor which measures an external light intensity; a temperature sensor which measures an external environmental temperature; an image correcting unit which corrects image data input to the image correcting unit on the basis of statistical data of the image data; a light adjusting unit which produces a light adjusting signal on the basis of a measurement signal produced from the external light intensity by the external light sensor; a temperature control unit which produces a temperature correcting signal on the basis of a measurement signal produced from the external environmental temperature by the temperature sensor; an adjusting unit which changes, upon a duty ratio of a brightness correcting signal being as a pulse width modulation (PWM) signal is less than a certain duty ratio, the duty ratio of the brightness correcting signal being as the PWM signal to a value more than the certain duty ratio, the adjusting unit providing the image correcting unit with a brightness adjusting signal for compensating for an increase of the light emitting brightness of the pixels caused by the change of the duty ratio; and a display control unit which produces a brightness correcting signal for controlling light emitting brightness of the pixels in the pixel unit on the basis of the light adjusting signal and the temperature correcting signal, wherein
