摘要:
In a current control driver that drives an active matrix device, a write current can be set larger and unevenness in currents can be reduced between elements receiving the currents. In the current control driver having an element circuit for each of the elements comprising a converting unit for converting an applied current into a voltage, a retaining unit for retaining the voltage converted by the converting unit, and a driving unit that converts the voltage retained by the retaining unit into an output current and supplies the output current, the converting unit is shared between two or more of the element circuits and a switch located between the shared converting units connects two or more of the converting units to one of the elements during a current supply period for the element.
