半導体装置、発光制御回路、及び、電子機器
Document Type and Number:
Japanese Patent JP6841099
Kind Code:
B2
Abstract:
A semiconductor device of the invention is a semiconductor device that controls a transistor that controls an electric current that flows through a light emitting element, the transistor including a gate that is connected to one end of a capacitor. The semiconductor device includes: a first terminal that is connected to the gate of the transistor and the one end of the capacitor; a second terminal that is connected to the other end of the capacitor; a first driving circuit that outputs a first control signal to the first terminal; and a second driving circuit that, in order to control the transistor in an on-state or an off-state, activates or deactivates a second control signal, and outputs the second control signal to the second terminal, the second control signal having a potential lower than a potential of the first control signal.
