Abstract: The disclosure describes procedures for dynamically employing a variable refresh rate at an LCD display of a consumer electronic device, such as a laptop computer, a tablet computer, a mobile phone, or a music player device. In some configurations, the consumer electronic device can include a host system portion, having one or more processors and a display system portion, having a timing controller, a buffer circuit, a display driver, and a display panel. The display system can receive image data and image control data from a GPU of the host system, evaluate the received image control data to determine a reduced refresh rate (RRR) for employing at the display panel, and then transition to the RRR, whenever practicable, to conserve power. In some scenarios, the transition to the RRR can be a transition from a LRR of 50 hertz or above to a RRR of 40 hertz or below.

Abstract: An electronic device such as a head-mounted device may have displays. The display may have regions of lower and higher resolution to reduce data bandwidth and power consumption for the display while preserving satisfactory image quality. Data lines may be shared by lower and higher resolution portions of a display or different portions of a display with different resolutions may be supplied with different numbers of data lines. Data line length may be varied in transition regions between lower resolution and higher resolution portions of a display to reduce visible discontinuities between the lower and higher resolution portions. The lower and higher resolution portions of the display may be dynamically adjusted using dynamically adjustable gate driver circuitry and dynamically adjustable data line driver circuitry.

Abstract: This disclosure provide various techniques for tracking emission profiles on an electronic display. An emission profile may be applied to the electronic display in order to illuminate certain pixels and deactivate (e.g., turn off) certain pixels in the electronic display to facilitate refreshing (e.g., programming with new image data) the deactivated pixels. A real-time row-based average pixel level or average pixel luminance calculation architecture may track the one or more EM profiles to accurately model EM profile behavior, which may enable accurate calculation of the average pixel level or average pixel luminance of the electronic display at any one point in time. The accurate average pixel level or average pixel luminance calculations effectuated by the EM profile tracking may be used to reduce the IR drop, improve real-time peak-luminance control, and improve the performance of under-display sensors, among other advantages.

Abstract: Conductive traces may be conformally wrapped around the side of a display panel that includes an array of display pixels. The conductive traces may electrically connect contacts on an upper surface of the display panel to corresponding contacts on a flexible printed circuit that is attached to a lower surface of the display panel. The side-wrapped conductive traces may be interposed between first and second insulating layers. The flexible printed circuit may have a multi-step interface that is electrically connected to the side-wrapped conductive traces. A system-in-package including a display driver integrated circuit may be mounted to the flexible printed circuit. The system-in-package may include a plurality of redistribution layers that electrically connect contacts on the display driver integrated circuit to contacts on the flexible printed circuit.

Abstract: In an embodiment, an electronic device includes an electronic display. The electronic display provides a programmable latency period in response to receiving a first image frame corresponding to first image frame data. The electronic display also displays the first image frame after the programmable latency period and during display of the first image frame, receives a second image frame corresponding to second image frame data. The electronic display also repeats display of the first image frame in response to receiving the second image frame.

Abstract: Systems, methods, and devices are described that may mitigate pixel and touch crosstalk noise. A touch processing system may compensate touch scan data to reduce the noise based on a luminance value. An image processing system may determine the luminance value based on image data and a display brightness value of an electronic display. Using the compensated touch scan data, the touch processing system may determine a proximity of a capacitive object to at least one touch sense region of the electronic display.

Abstract: An electronic device display may have pixels formed from crystalline semiconductor light-emitting diode dies, organic light-emitting diodes, or other pixel structures. The pixels may be formed in a display panel having a single substrate or an array of display panel tiles. The display panel has inwardly facing display panel contacts that mate with corresponding outwardly facing interconnect substrate contacts on an interconnect substrate. The interconnect substrate may have areas with compound curvature that are overlapped by the display panel. To enhance flexibility of the interconnect substrate, the interconnect substrate may have flexibility enhancement openings and/or may be formed from a material with a low elastic modulus such as silicone or other elastomeric material.

Abstract: Systems, methods, and devices for adjusting image display on an electronic display by predicting a temperature change of the electronic display due to heat-producing components near the display or due to changes in content. An electronic device may include an electronic display and processing circuitry. The electronic display may include pixels with behaviors that vary with temperature. As such, the processing circuitry may generate image data to send to the electronic display and adjust the image data or vary an operation of the electronic display based at least in part on a predicted temperature effect on at least part of the active area of the electronic display. The processing circuitry may determine the predicted temperature effect at least in part due to a first heat producing component or changes in content of the image data.

Abstract: An electronic device may include a display for displaying image content to a user and dynamic image stabilization circuitry for dynamically compensating the image content if the device is moving unpredictably to help keep the image content aligned with the user's gaze. The electronic device may include sensors for detecting the displacement of the device. The dynamic image stabilization circuitry may include a usage scenario detection circuit and a content displacement compensation calculation circuit. The usage scenario detection circuit receives data from the sensors and infers a usage scenario based on the sensor data. The content displacement compensation calculation circuit uses the inferred usage scenario to compute a displacement amount by which to adjust image content. When motion stops, the image content may gradually drift back to the center of the display.
