CURRENT DRIVE APPARATUS AND DRIVE METHOD THEREOF, AND DISPLAY APPARATUS USING THE APPARATUS

摘要

A current drive apparatus operates a plurality of loads by applying a current thereto. The apparatus includes a plurality of output terminals (Tout) to which the loads are respectively connected. A single current generation circuit (10A) outputs an operating current having a predetermined current value. A plurality of current storage circuits (30A) are provided in accordance with the respective output terminals, sequentially fetch and hold the operating current and simultaneously output the drive current based on the operating current to the respective output terminals. The operating current has a current value according to an input signal. The current storage circuit (30A) includes a voltage component holding section which fetches the operating current outputted from the current generation circuit and holds a voltage component corresponding to a current value of the operating current.
