    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.

    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 display device may include rows of pixels that displays image data on a display, data lines coupled to the rows of pixels, and a digital-to-analog converter (DAC) that outputs a ramp voltage signal including a data voltage to be depicted on a first pixel of the rows of pixels. The display device may also include a capacitor that receives the ramp voltage signal via the DAC and a circuit that sends a control signal to a circuit component that causes the DAC to couple to the capacitor via one of the data lines for a duration of time that comprises a first time when the ramp voltage signal is below the data voltage and a second time when the ramp voltage signal is approximately equal to the data voltage. The capacitor is coupled to the DAC when the ramp voltage signal is greater than zero.
