Abstract:
Gate line driver circuitry applies an output pulse to each of several gate lines for a display element array. The circuitry has a number of gate drivers each being coupled to drive a respective one of the gate lines. Each of the gate drivers has an output stage in which a high side transistor and a low side transistor are coupled to drive the respective gate line, responsive to at least one clock signal. A pull down transistor is coupled to discharge a control electrode of the output stage. A control circuit having a cascode amplifier is coupled to drive the pull down transistor as a function of a) at least one clock signal and b) feedback from the control electrode. Other embodiments are also described and claimed.
