Driving circuit of liquid crystal display
Abstract:
An exemplary driving circuit of a liquid crystal display includes a delay circuit (130), a first transistor (140), a second transistor (160), a first bias resistor (R1), and a second bias resistor (R2). The first transistor includes a source electrode for receiving a first voltage signal, and a drain electrode for providing the first voltage signal to a first external circuit. The second transistor includes an emitter electrode for receiving a second voltage signal, and a collector electrode for providing the second voltage signal to a second external circuit. The delay circuit includes a first control pin (137) connected to the gate electrode of the first transistor, and a second control pin (138) connected to the base electrode of the second transistor. The delay circuit is configured for delaying the first voltage signal for a first predetermined time period and the second voltage signal for a second predetermined time period.
