    Abstract: Methods and devices employing circuitry for dynamically adjusting bandwidth control of a display interface are provided. The display interface or image content is dynamically adjusted to support both high-speed image data (e.g., 120 Hz image data) and lower-speed content (e.g., 60 Hz content). For example, in some embodiments, additional pixel pipelines and/or processing lanes may be activated during the rendering of high-speed image data, but not during the rendering of low-speed image data. Additionally or alternatively, high-speed image data, but not low-speed data, may be compressed to render high-speed content over an interface that supports only low-speed content.

    Abstract: A method for simplifying the host-to-display subsystem communications and consolidating the non-volatile memory requirements into a PMIC (power management integrated circuit) is disclosed. Hardware and software resource reduction in both the client devices (located in the display subsystem) and the host System on a Chip (SOC) can be realized with a novel PMIC design. The novel PMIC design achieves the resource reduction by providing for the following features: (1) Single-point communication, (2) Single-point notification, (3) Client device status storage, (4) Client device initialization from PMIC non-volatile memory, and (5) Subsystem calibration retrieval from PMIC non-volatile memory.

    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: A pixel array may be illuminated with backlight illumination from a backlight. The backlight may include a two-dimensional array of light-emitting diodes, with each light-emitting diode being placed in a respective cell. Different light-emitting diodes may have unique brightness magnitudes based on the content of the given display frame. Driver integrated circuits may control one or more associated light-emitting diodes to have a desired brightness level. The driver integrated circuits may be formed in an active area of the backlight. The driver integrated circuits may be arranged in groups that are daisy chained together. A digital signal (that includes information such as addressing information) may be propagated through the group of driver integrated circuits. To manage thermal performance of the backlight, the backlight may include a thermally conductive layer and/or a heat sink structure. To increase the efficiency of the backlight, the backlight may include one or more reflective layers.

    Abstract: An electronic device such as a voice-controlled speaker device may have a housing characterized by a vertical longitudinal axis. A flexible substrate such as a flexible mesh substrate with component support regions coupled by flexible segments may be wrapped around the housing and the vertical axis. The housing may have surface regions with compound curvature. The flexible substrate may conform to the regions with compound curvature. A fabric spacer layer may be interposed between the flexible substrate and the housing. Electrical components such as input-output devices may be mounted to the component support regions. A display may be formed from an array of light-emitting devices that are mounted on respective component support regions. Light from the light-emitting devices may pass through the fabric spacer layer toward the housing and back out away from the housing. An outer fabric layer may cover the mesh.
