Driving circuit and display device

摘要

In a circuit driving a capacitive load Cp, current passed through a transistor Q 3 , a diode D 1 and a recovering coil L is passed through lines L 1 , L 2 , and the inductance components of the lines L 1 and L 2 , and the drain-source capacitances of the transistors Q 1 and Q 2 generate LC resonance. Capacitors C 1 and C 2 are connected in parallel to the drain-source regions of the transistors Q 1 and Q 2 to increase the total drain-source capacitance and reduce the resonance frequency, so that unwanted electromagnetic wave radiation in a frequency band affecting other electronic devices is suppressed.
