    Abstract: An electronic device may have a display overlapped by a cover layer. Portions of the surface of the display and cover layer may have curved profiles. The display may include a flexible substrate with bent edge portions protruding from a central region. Gaps may be formed between regions of pixels on a common display substrate or between separate display substrates. A light source may emit light through a gap. Optical components such as sensors may be aligned with windows in the display. The windows may be formed from transparent portions of a display layer that are surrounded by pixels. A frame may be used to support the flexible substrate. The frame may have a metal portion and a polymer portion molded to the metal portion. Openings and other structures in the frame may accommodate components such as optical sensors. Components may be aligned with frame openings and display windows.

  • Patent number: 11714126
    Abstract: A detection circuit for detecting a clock signal includes a multiplexer, a digital-to-analog converter, a comparator, and a counter. The multiplexer outputs either a first signal or a second signal as a selection signal. The digital-to-analog converter outputs a reference voltage according to the selection signal. The comparator compares the clock signal to the reference voltage to generate a comparison signal. The counter counts a reference clock signal to generate an overflow signal, and resets the overflow signal according to the comparison signal. The overflow signal indicates the amplitude of the clock signal.

  • Patent number: 11650368
    Abstract: An electronic device may have a display that displays an image. The image may be viewed through a display cover layer that overlaps the display. The display cover layer may include an optical coupling layer such as a coherent fiber bundle. A pixel expansion layer such as a diffractive layer may be incorporated between the optical coupling layer and a protective layer. The diffractive layer may create duplicate pixels to occupy otherwise non-light-emitting areas on the output surface of the display cover layer. The diffractive layer may also create duplicate pixels that overlap adjacent pixels to allow for brightness averaging. An adhesive layer or the protective layer may be used to form diffractive elements for the diffractive layer. An adhesive layer having a high index of refraction may be interposed between the optical coupling layer and the display panel to mitigate undesired reflections of ambient light.
