Patent ID: 7304621

Claim:
A display apparatus, comprising: a display panel provided with a pixel section including a light-emitting device driven by a current and with a signal line connected to the pixel section; and a source driver for supplying a drive current to the pixel section via the signal line, wherein the source driver includes: a register for latching display data having N bits and for outputting the display data; a timing control unit for outputting a control signal; and a current driver for allowing the drive current which has been set at an arbitrary value to flow during a given period in a current setting mode, while allowing the drive current which has been set with the display data output from the register to flow during operation periods other than the given period, in accordance with the control signal, wherein thr current driver includes: a current moder D/A converter including N current sources for outputting currents according to the bits of ther display data; an additional current source for outputting a current with an arbitrary value; and a first switch for receiving the control signal and electrically connecting the additional current source and the pixel section to each other only during the given period in the current setting mode.
