Abstract
There is provided a display drive apparatus for operating, in accordance with display data, a current control type optical elements each having a display pixel provided with the optical element and a drive element which supplies a driving current to the optical element. The display drive apparatus includes a gradation signal creating circuit which generates a gradation signal corresponding to a luminance gradation of the display data and supplies the gradation signal to the display pixel, a threshold voltage detection circuit which detects a threshold voltage peculiar to the drive element of the display pixel, and a compensation voltage application circuit which generates a compensation voltage for compensating for the threshold voltage of the drive element on the basis of the threshold voltage and applies the compensation voltage to the drive element.
