DRIVING METHOD AND APPARATUS OF A PNPN SEMICONDUCTOR DEVICE

摘要

A driving method of a pnpn semiconductor device includes the steps of applying a voltage higher than a holding voltage of the pnpn semiconductor device to an anode electrode thereof, supplying a control signal light to the pnpn semiconductor device to set the pnpn semiconductor device into ON state, and supplying an information signal light to the pnpn semiconductor device to emit an output light. The control signal light and the information signal light is timesequentially supplied to the pnpn semiconductor device under the voltage applied thereto.
