Abstract:
A display drive apparatus includes a detection voltage applying circuit that applies a predetermined detection voltage to the drive element of the pixel drive circuit, a voltage detecting circuit that detects a voltage value corresponding to a device characteristic unique to the drive element after a predetermined time elapses after the application of the detection voltage to the drive element by the pixel drive circuit, and a gradation designating signal generating circuit that generates a gradation designating signal based on an absolute value of a voltage component according to a gradation value of display data and a value, acquired by multiplying an absolute value of the voltage value detected by the voltage detecting circuit, by a constant greater than 1, and applies the gradation designating signal to the pixel drive circuit, whereby a change in device characteristic.
