    Abstract: A liquid crystal display may have a layer of liquid crystal material. The display may have an array of display pixel circuits. The display pixel circuits may each include a display pixel electrode that applies electric fields to a corresponding portion of the liquid crystal material. Thin-film transistor circuitry and other structures in the display pixels may control operation of the display pixels circuits. The thin-film transistor circuitry may be configured to handle operation of the display at multiple refresh rates. To accommodate multiple refresh rates, each pixel circuit may include a pair of transistors. A first transistor is used to apply data signals from a data line to the display pixel electrode. A storage capacitor is used to maintain the data signal on the electrode. The second transistor may be used to adjust the capacitance of the storage capacitor depending on the refresh rate of the display.

    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. Each gate start pulse may only be released at the end of an IFP interval. In another suitable arrangement, dummy gate driver units may be interposed among active gate driver units. Gate output signals may propagate through the dummy gate driver units during the IFP internal. In another suitable arrangement, each active gate driver unit may be provided with a buffer portion that protects at least some transistor in the gate driver unit from undesired stress.

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.
