Abstract:
1. A driving circuit for a light-emitting device, said driving circuit outputting a drive current from an output terminal to said light-emitting device in accordance with a signal current input from an input terminal, said driving circuit comprising: a drive transistor; a capacitor connected between a gate and a source of said driving transistor; a resistance device and a first switch arranged in series between a drain of said drive transistor and said input terminal; a second switch configured to connect said gate and said drain of said drive transistor through said resistance device when said first switch is closed; and a third switch disposed in a path through which a drain current of said drive transistor flows from said output terminal to said light-emitting device, wherein said resistance device is configured to increase its resistance in accordance with a cumulative amount of a passing current.
