Patent ID: 7907105

Claim:
A display apparatus comprising: a light-emitting device; a pixel drive circuit which is connected to the light-emitting device; a display driver including a voltage adjustment section which adjusts a potential of an adjustment voltage such that the potential of the adjustment voltage is approximated to a potential which is changed in accordance with a change amount of characteristics inherent to the pixel drive circuit when a reference current having a predetermined current value is supplied to the pixel drive circuit; and a data line which connects the display driver and the pixel drive circuit; wherein the display driver includes a voltage comparison section which supplies the reference current to the pixel drive circuit and compares the potential adjusted by the voltage adjustment section and the potential which is changed in accordance with the change amount of the characteristics inherent to the pixel drive circuit when the reference current is supplied to the pixel drive circuit; and wherein the display driver includes an offset voltage generation section which generates an offset voltage based on a result of the comparison made by the voltage comparison section.
