DISPLAY DRIVE APPARATUS, DISPLAY APPARATUS AND DRIVE CONTROL METHOD THEREOF

摘要

There is provided a display drive apparatus (130) for operating, in accordance with display data, a current control type optical elements (OEL) each having a display pixel (PX) provided with the optical element (OEL) and a drive element (Tr13) which supplies a driving current to the optical element. The display drive apparatus includes a gradation signal creating circuit (130) 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 (140) which detects a threshold voltage peculiar to the drive element of the display pixel, and a compensation voltage application circuit (150) 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.
