Abstract: An electronic device may be provided with a display. The display may be a variable frame rate display capable of adaptively adjusting a frame rate at which display frames are displayed in response to information associated with the current state of operation of the device. The information may be gathered using control circuitry in the electronic device. The control circuitry may gather the information for adjusting the frame rate by monitoring the electronic device power supply configuration, other device components, the type of content to be displayed, and user-input signals. The control circuitry may adjust the frame rate based on the gathered information by increasing or decreasing the frame rate. The control circuitry may be formed as a portion of display control circuitry for the device such as a display driver integrated circuit or may be formed as a portion of storage and processing circuitry external to the display.

Abstract: An electronic device may have a display with pixels configured to display an image. The pixels may be overlapped by a cover layer. The display may have peripheral edges with curved cross-sectional profiles. An inactive area in the display may be formed along a peripheral edge of the display or may be surrounded by the pixels. Electrical components such as optical components may be located in the inactive area. An image transport layer may be formed from a coherent fiber bundle or Anderson localization material. The image transport layer may overlap the pixels, may have an opening that overlaps portions of the inactive area, may have an output surface that overlap portions of the inactive area, and/or may convey light associated with optical components in the electronic device.

Abstract: An electronic device may have a display overlapped by an image transport layer such as a coherent fiber bundle or layer of Anderson localization material. The image transport layer may have an input surface that receives an image from the display and a corresponding output surface to which the image is transported. The input surface and output surface may have different shapes. During fabrication of the image transport layer, molding techniques, grinding and polishing techniques, and other processes may be used to deform the image transport layer and the shape of the output surface. To help reduce ambient light reflections and stray light, light-absorbing structures may be incorporated into the image transport layer and other structures overlapping the display.

Abstract: An electronic device may include a display and an optical sensor formed underneath the display. A pixel removal region on the display may at least partially overlap with the sensor. The pixel removal region may include a plurality of non-pixel regions each of which is devoid of thin-film transistors. The plurality of non-pixel regions is configured to increase the transmittance of light through the display to the sensor. In addition to removing thin-film transistors in the pixel removal region, additional layers in the display stack-up may be removed. In particular, a cathode layer, polyimide layer, and/or substrate in the display stack-up may be patterned to have an opening in the pixel removal region. A polarizer may be bleached in the pixel removal region for additional transmittance gains. The cathode layer may be removed using laser ablation with a spot laser or blanket illumination.

Abstract: An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a plurality of transparent windows that overlap the optical sensor. Each transparent window may be devoid of thin-film transistors and other display components. The plurality of transparent windows is configured to increase the transmittance of light through the display to the sensor. The transparent windows may have non-periodic portions to mitigate diffraction artifacts in light that passes through the display to the optical sensor. The transparent windows may be shifted by a random amount in a random direction relative to a grid defining point and/or may be randomly rotated to increase the non-periodicity. A transparency gradient may be formed between the transparent windows and the surrounding opaque portion of the display. The transparent windows may be defined by non-linear edges.

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 and may have bent edge portions protruding from a central region. Gaps may be formed between regions of pixels on a common substrate or between separate display panels. An image transport layer formed from a coherent fiber bundle or a layer of Anderson localization material configured to exhibit two-dimensional transverse Anderson localization of light may have an input surface that receives an image from adjacent display pixels and an output surface on which the image is displayed. The output surface may have a curved profile and may exhibit compound curvature. The input surface may have a profile with curved portions or other shapes. Image transport layers can be used to cover gaps between sets of pixels.

Abstract: A plurality of fibers may be included in an electronic device display to allow the display to have a curved output surface. Each fiber may guide light from one or more display pixels on the display panel to a display output surface. The fibers may be bent, allowing light from the display pixels to be displayed on a three-dimensional display output surface of any desired shape. The fibers may be formed from a high refractive index core surrounded by a cladding. The fibers may be formed from an activated photoactive material. The fibers may cover the entire display panel, the periphery of the display panel, or the corners of the display panel. The display panel may have one or more bends. Polarizing fibers may be used to both guide light from the display panel and serve as a linear polarizer for the display.

Abstract: A display may have an active area that includes display pixels. The display may include an inactive notch region that extends into the active area. Data lines may provide image data from display driver circuitry to the display pixels. The image data may include data signals that correspond to portions of the display that do not include pixels, such as the inactive notch region. The null data signals may cause nonuniformities in the displayed image. The null data signals may be adjusted to minimize the nonuniformities. Null data signals corresponding to the inactive notch region may be adjusted to have gray levels that gradually decrease with distance from the border between the inactive notch and the active area. All of the data signals corresponding to the inactive notch may be set to a uniform gray level.
