摘要： An LCD gate driver circuitry having a control circuit to adjust the driving current according to a bias control signal, wherein the control circuit comprises a plurality of PMOS switching elements connected in parallel and a plurality of NMOS switching elements connected in parallel. These switching elements form a plurality of PMOS/NMOS switching element pairs. Each of the pairs serves as a current booster stage in the gate driver circuitry. The “ON”/“OFF” state of each switching element pair is controlled by a separate bias signal so that the switching element pairs can be selectively turned on in order to adjust the driver current as needed. As such, the same gate driver circuitry can be used with different LCD panels.

摘要： A phototransistor structure is disclosed. A sidewall is grown on the collector side and under the base. The surface of the sidewall is formed with a sidewall contact. When the contact is connected to an external voltage, the holes accumulated at the junction of the base and emitter can be quickly removed. This solves the problem in the prior art that using a bias between the base and the emitter to remove holes usually results in a large dark current (bias current), power consumption, and diminishing optoelectronic conversion gain.
