Abstract: An electronic device may include display pixels and a display cover layer. The display cover layer may be formed from a transparent material such as glass. The display cover layer may have a nanotextured upper surface to improve the optical and mechanical characteristics of the display cover layer. The nanotextured upper surface may include first and second different types of nanostructures. The first type of nanostructures may have a relatively low aspect ratio and a first average height. The second type of nanostructures may be elongated nanostructures with a relatively high aspect ratio and a second average height that is greater than the first average height.

Abstract: An electronic device may have a display with touch sensors. One or more shielding layers may be interposed between the display and the touch sensors. The shielding layers may include shielding structures such as a conductive mesh structure and/or a transparent conductive film. The shielding structures may be actively driven or passively biased. In the active driving scheme, one or more inverting circuits may receive a noise signal from a cathode layer in the display and/or from the shielding structures, invert the received noise signal, and drive the inverted noise signal back onto the shielding structures to prevent any noise from the display from negatively impacting the performance of the touch sensors. In the passive biasing scheme, the shielding structures may be biased to a power supply voltage.

Abstract: An electronic device may include a projection display that has a high transparency when the display is turned off. The high off-state transparency may create the appearance of the display being invisible in the off-state, which may be desirable in certain electronic devices. The projection display may include an adjustable diffuser, a spatial light modulator that projects images onto the adjustable diffuser, a mirror that reflects the images from the spatial light modulator to the adjustable diffuser, and a light source that provides light to the spatial light modulator. The projection display may also include an adjustable opacity layer that is controlled based on detected ambient light levels. The projection display may also include an adjustable reflectivity layer. The adjustable diffuser and/or light source may be pixelated to increase contrast in the projection display.

Abstract: Front-of-screen performance of the electronic display may be highly sensitive to timing settings of emission and anode reset frequencies. Changes in the timing settings may result in diverging brightness and color performance on the electronic display, which may negatively impact user experience. In some cases, emission frequency of the self-emissive display pixels may be fixed at a value, such as 120 Hertz (Hz), 240 Hz, or 480 Hz. The anode reset frequency may be set at a divisor of the emission frequency. Some refresh rates may be divisors of the pixel emission frequency. However, other refresh rates may not be divisors of the pixel emission frequency. For such non-divisor refresh rates, different driving schemes may be used to compensate for a difference from the pixel emission frequency.

Abstract: A system may have an external display that presents content to viewers outside of the system. The external display may have a display panel with an array of pixels formed from light-emitting diodes. Optical films that help collimate and homogenize light from the light-emitting diode pixels may overlap the light-emitting diodes. A transparent cover may overlap the display. The transparent cover may have an outer surface and an opposing inner surface. The outer surface and inner surface may be planar or may have a curved cross-sectional profile. An optical louver layer or other solar rejection layer may be interposed between the inner surface of the transparent cover and the display panel. The louver layer may have a series of elongated parallel louvers formed from an opaque polymer or other material. The louvers may be configured to block sunlight reflections while allowing images on the display panel to be viewed.

Abstract: An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. The lenticular lenses may be configured to enable stereoscopic viewing of the display such that a viewer perceives three-dimensional images. The display may render different content layers that present different classes of content. The different classes of content may have different characteristics. As an example, a first class of content may be static content whereas a second class of content may be dynamic content. The different characteristics of each class of content may be leveraged to use a hybrid approach for content processing. The hybrid content processing may take advantage of different layers needing to be updated at different frequencies and may take advantage of sparse content in some of the layers.

Abstract: A system may have a display that includes a plurality of light sources such as light-emitting diodes. The display may be an exterior display that is routinely operated in daytime conditions where ambient light levels are very high. To increase contrast in an exterior display, the display may include a sunlight blocking element. A static sunlight blocking element may include a louver film with asymmetric light blocking portions. The system may include an ambient light sensor that is configured to determine ambient light levels. Based on the detected ambient light level, control circuitry in the system may adjust one or more adjustable components in the display. The display may include an adjustable diffuser that has at least two states with different haze levels. The display may include an adjustable tint layer that has at least two states with different transmission levels.
