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: Embodiments described herein generally take the form of an electronic device including a primary and secondary display; at least the secondary display is force-sensitive and further has its force-sensing circuitry in-plane with the display. The secondary display and force-sensing circuitry may be encapsulated between two glass layers that are bonded to one another by a frit. In some embodiments the force-sensing circuitry is formed from, or constitutes part of, the frit.

Abstract: An electronic device may be provided with a display. The display may include a backlight having an array of locally dimmable light sources. Control circuitry may provide control signals to the backlight to produce light at different brightness levels. When the brightness level is below a threshold, the control circuitry may use pulse-width-modulation control signals to control the light sources in the backlight. When the brightness level is above the brightness threshold, the control circuitry may use analog control signals to control the light sources in the backlight. The control circuitry may adjust the threshold to achieve different dimming ranges for different brightness settings. A low brightness setting, for example, may have a lower threshold and lower dimming range than a high brightness setting, which may help produce darker darks when the display operates in a low brightness setting.

Abstract: An electronic device may have a main display and an ancillary display. The device may also have a backlit keyboard with glyphs. An ambient light sensor may measure ambient light levels. Control circuitry in the laptop computer may adjust the color cast of content on the ancillary display depending on whether the content contains glyphs or other input display content or whether the content contains images, color gradients, or other output display content. Input display content may be matched in color cast to the color cast of the glyphs, which may be determined based on backlight status and/or measured ambient light information. Output content may be color matched to the main display.

Abstract: A display may have an array of display pixels for displaying images for a user. A backlight unit may provide backlight for the display pixels. The backlight unit may have a substrate such as a printed circuit substrate. An array of locally dimmable backlight elements may be mounted on the substrate. The substrate may be mounted against an inner surface of a metal electronic device housing or other support structure in an electronic device. Each backlight element may have a semiconductor package containing a semiconductor die. The semiconductor die may have a light-emitting diode and a light-emitting-diode control circuit. The light-emitting-diode control circuit may have a pair of transistors and a capacitor. One of the transistors may be connected in series with the light-emitting diode. The light-emitting diode control circuit may receive control signals on a gate line terminal and a source line terminal.

Abstract: A display may receive image data to be displayed for a user of an electronic device. Display driver circuitry in the display may include a timing controller that receives the image data. The timing controller can analyze frames of the image data to determine average luminance values for the frames. The display may include an array of organic light-emitting diode display pixels. Each display pixel may include a light-emitting diode. A transistor in each display pixel may be coupled in series with the light-emitting diode between positive and ground power supply terminals. The timing controller can limit peak luminance in the image data that is displayed on the array of display pixels as a function of average luminance. The timing controller can also direct power regulator circuitry to adjust a power supply voltage applied to the positive power supply terminal based on the average luminance.

Abstract: A display may include an array of pixels covered by lenticular lenses. The lenticular lenses may cause expansion of light primarily in a horizontal direction. To improve the perceived resolution of the display, the horizontal resolution of the pixels on the display may be increased. In one possible layout, each pixel includes one red sub-pixel, one blue sub-pixel, and one green sub-pixel. The sub-pixels may be non-square rectangular. The sub-pixels may be the same size or may have the same widths and different heights. Each pixel may be asymmetric about a horizontal axis. In a given row, the pixels may alternate between first and second layouts. The second layout may be a vertically flipped version of the first layout.

Abstract: A privacy film may have a light-blocking layer that is interposed between first and second transparent substrates. The light-blocking layer may have a plurality of opaque portions and a plurality of transparent portions. The opaque portions may be shaped to ensure light from the display is directed only to the primary viewer of the display. Each opaque portion of the light-blocking layer may extend along a respective longitudinal axis between the first and second transparent substrates. Privacy films used to cover curved displays may have opaque portions that extend along longitudinal axes that have different angles relative to the transparent substrates. Opaque portions in the edge of the privacy film may have longitudinal axes that are at non-perpendicular angles with respect to the transparent substrates. A privacy film for a curved display may also include a light-redirecting layer such as a prism layer or a liquid crystal layer.
