0923067-A1 is referenced by 77 patents and cites 6 patents.

A display apparatus (100) is provided with a current driving type light-emitting device (224) and a driving device (223) for controlling a driving current flowing through the light-emitting device for each pixel. The display apparatus comprises power source units (13, 14) for supplying power for causing a driving current to flow via the driving device to the light-emitting device via a power source wire and signal wire driving units (11, 12) for supplying a data signal to the driving device via signal wires (131, 132).; In addition, voltage adjusting units (16-23) adjust a voltage from a power source from the power source units or a data signal from the signal wire driving unit so that a quantity of current of a driving current flowing through the light-emitting device in such a manner that, when a data signal of a predetermined voltage is supplied to the driving device via signal wires or a quantity of emitted light emitted from the light-emitting device comes close to a predetermined reference value.
