摘要:
A display drive apparatus for driving a display pixel including a light-emitting element and a drive element in which one end of a current path is connected to the light-emitting element. The display drive apparatus has a specific value detection section detecting a difference value between a measured voltage detected at one end of a data line when a reference current is applied via the data line and a standard voltage corresponding to the reference current so as to obtain a specific value corresponding to variation of an element characteristic of the drive element, and a gradation signal correction section generating a corrected gradation signal by correcting a gradation signal according to display data based on the specific value so as to apply the corrected gradation signal from the one end of the data line to the display pixel.
