ABSTRACT:
A display apparatus which can display an image at a proper luminance corresponding to a video signal irrespective of a temperature-related change or a change with the passage of time. The display apparatus has: a current source for generating a reference current; and a reference transistor having an input terminal for a power voltage, an output terminal to which the current source is connected, and a control terminal connected to the output terminal and having almost the same electrical characteristics as those of a driving transistor for supplying a drive current to a light emitting device serving as a pixel. The driving transistor is driven by a voltage (reference control voltage) on the control terminal of the reference transistor. The loss of electric power can be suppressed by the driving method of this apparatus.
