Abstract: A display may have an array of pixels. Rows of pixels may receive gate line signals over gate lines. Display driver circuitry may have an adjustable clock generator that generates a series of clock pulses with different respective fall times to help equalize kickback voltages in the pixels of different rows. Within each row, gate lines may be provided with multiple parallel lines shorted at a series of tap points to help equalize kickback voltages across the pixels of different columns. A clock path may be formed between the clock generator and gate driver circuits. The clock path may run along an edge of the array of pixels. To help equalize kickback voltages in the pixels of different rows, the clock path may have first and second parallel metal lines that are selectively shorted to each other at a series of tap point locations along the clock path.

Abstract: A display may have an array of pixels arranged in rows and columns. Each pixel may have a transistor for controlling the amount of output light associated with that pixel. The transistors may be thin-film transistors having active areas, first and second source-drain terminals, and gates. Gate lines may be used to distribute gate control signals to the gates of the transistors in each row. Data lines that run perpendicular to the gate lines may be used to distribute image data along columns of pixels. The gate lines may be connected to gate line extensions that run parallel to the data lines. The data lines may each overlap a respective one of the gate line extensions. Vias may be used to connect the gate line extensions to the gate lines. The gate line extensions may all have the same length.

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.

Abstract: A display may have a color filter layer and a thin-film transistor layer. A layer of liquid crystal material may be located between the color filter layer and the thin-film transistor layer. Column spacers may be formed on the color filter layer to maintain a desired gap between the color filter and thin-film transistor layers. Support pads may be used to support the column spacers. Different column spacers may be located at different portions of the support pads to allow the support pad size to be reduced while ensuring adequate support. Lateral movement blocking structures such as circular rings may be used to prevent column spacer lateral movement. Subspacers located over pads may be used to create friction that retards lateral movement. Lateral movement may also be retarded by receiving column spacers in trenches or other recesses formed on a thin-film transistor layer.
