Patent ID: 7123220

Claim:
A self-luminous display device comprising: a plurality of luminous elements forming a display screen; a driving signal supply section which supplies driving signals to said luminous elements; and a luminance adjusting section which equally changes the ratios of luminous time to non-luminous time of said luminous elements by switching the driving signals from said driving signal supply section to adjust luminance of the display screen; wherein said driving signal supply section includes a plurality of element driving sections which respectively change the driving signals of said plurality of luminous elements according to a video signal, said luminance adjusting section includes a dimmer switch portion which switches the driving signal at least once in an updating period of the video signal to adjust the luminance of the display screen, said dimmer switch portion including at least one dimmer switch, each dimmer switch configured to switch the driving signal of a plurality of said luminous elements; and wherein said luminous elements are formed together with said element driving section on a single panel, and each of said element driving sections includes a driving transistor which is connected in series with a corresponding one of said luminous elements between paired power lines and causes a driving signal corresponding to the gate voltage thereof to flow through the corresponding luminous element, a pixel switch which applies a voltage of the video signal to the driving transistor as the gate voltage thereof, and a capacitor which holds the gate voltage of the driving transistor.
