Abstract: In situations with reduced image changes, display panels, such as the ones disclosed herein, may reduce their power consumption by performing self-refresh cycles, in which they may display locally stored data in the display panel instead of retrieving it from an image buffer. Methods and circuitry for management of the self-refresh cycle may reduce jitter, luminance errors, and/or flickers that may be caused by untimely self-refresh cycles that may occur as a result of latency in the image buffer. In some implementations, the display panel may have a dedicated low latency input that notifies an arrival of an incoming image. In some implementations, the self-refresh cycles of the panel may be managed by a host or a buffer that is responsible for sending the images.

Abstract: A display driver is disclosed that reduces first frame dimming and flicker in light-emitting diode pixels of a display device. The display driver may receive a display brightness value and determine a value of a dynamic supply voltage parameter based on the display brightness value. Over a first time interval, the display driver may apply a supply voltage that is based on the dynamic supply voltage parameter to one of a gate of a drive transistor of a light-emitting-diode circuit and a channel of the drive transistor. Over a second time interval, the display driver may apply a parking voltage to an anode of a light-emitting diode of the light-emitting-diode circuit and to the channel of the drive transistor. The value of the parking voltage may be below a threshold voltage of the light-emitting diode and correspond to the value of the dynamic supply voltage parameter.

Abstract: A touch screen is disclosed. The touch screen comprises a first touch node electrode associated with a first display pixel, the first display pixel coupled to a first gate line. The touch screen also comprises a second touch node electrode associated with a second display pixel, the second display pixel coupled to a second gate line. The touch screen also comprises a voltage source coupled to a first gate line routing and a second gate line routing, wherein the first gate line is coupled to the first gate line routing, and the second gate line is coupled to the second gate line routing.

Abstract: A touch sensor panel is disclosed. The touch sensor panel can include a plurality of touch nodes, the plurality of touch nodes including a first set of touch nodes and a second set of touch nodes, different from the first set of the touch nodes. In some examples, sense circuitry can be configured to, during a first scan, sense a first combined touch signal of the first set of the touch nodes, and during a second scan, sense a second combined touch signal of the second set of the touch nodes. A touch processor can be configured to determine a touch image at the plurality of touch nodes based on the first and second combined touch signals.
