Abstract
A touch screen display may include gate line driver circuitry coupled to a display pixel array. The display may be provided with intra-frame pausing (IFP) capabilities, where touch or other operations may be performed during one or more intra-frame blanking intervals. In one suitable arrangement, a gate driver circuit may include multiple gate line driver segments each of which is activated by a separate gate start pulse is that received through a demultiplexing circuit. In another suitable embodiment, the gate driver circuit may include analog or digital gate driver units that include control circuits for selectively (dis)charging internal nodes in the gate driver circuit so as to balance the amount of stress that is experienced by a drive transistor in gate driver units at or near an IFP row and the amount of stress that is experienced by the remaining gate driver units.
