Abstract:
A display may have gate driver circuitry that include a series of linked gate driver circuits each of which has an output and has an input coupled to the output of a preceding one of the gate driver circuits. Bootstrapping circuitry may be provided in the gate driver circuitry. Each gate driver circuit may have a bootstrapping circuit that includes transistors and a bootstrapping capacitor. Bootstrapping efficiency may be enhanced by configuring the bootstrapping capacitor to reduce parasitic capacitances. A transistor in each bootstrapping circuit may have first and second source-drain terminals, and a gate terminal that lies between the first and second source-drain terminals and that runs parallel to the first and second source-drain terminals. The bootstrapping capacitor may have a first electrode formed from the gate terminal and a second electrode that overlaps the first electrode and that lies between the first and second source-drain terminals.
