  • Patent number: 10354607
    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.

  • Publication number: 20180047342
    Abstract: This application relates to methods and apparatus for refreshing a display device at various frequencies. Specifically, multiple areas of the display device can be refreshed concurrently at different frequencies. In this way, when static content is being displayed in certain areas of the display device, those certain areas can be refreshed at a lower rate than areas displaying dynamic content such as video or animation. By refreshing at lower rates, the energy consumed by the display device and subsystems associated with the display device can be reduced. Additionally, processes for reducing flicker when refreshing the display device at different refresh rates are disclosed herein.

  • Patent number: 9727165
    Abstract: A display may have an array of pixels controlled by display driver circuitry. Gate driver circuitry supplies gate line signals to rows of the pixels. The gate driver circuitry may include blocks of gate driver circuits each having an output coupled to a respective one of the gate lines. The gate driver circuits of each block are coupled in a chain to form a shift register. Each block has a local block-level gate start pulse generator. The display driver circuitry has a display driver circuit that supplies a gate start pulse clock to each of the local block-level gate start pulse generators. The local block-level gate start pulse generators create gate start pulses that are applied to the first gate driver circuit in each shift register. The display driver circuit may delay the gate start pulse clock when it is desired to implement an intraframe pause.
