Abstract: A head-mounted device may have an inner display that displays images for a user and an outer display that informs nearby people of the status of the user and inner display. For example, the outer display may display an image of a face, an abstract layer, or both, depending on whether the inner display is operating in passthrough mode, mixed reality mode, or virtual reality mode. An ambient light sensor in the head-mounted device may be used to measure the brightness and color of ambient light. The white point of the face layer on the outer display may be adapted to the color of ambient light, whereas the white point of the abstract layer on the outer display may remain fixed. The white point of a display may be a correlated color temperature setting (e.g., measured in degrees Kelvin) that determines the warmth or coolness of displayed colors.

Abstract: A lenticular display may be formed with convex curvature. The lenticular display may have a lenticular lens film with lenticular lenses that extend across the length of the display. The lenticular lenses may be configured to enable stereoscopic viewing of the display. To enable more curvature in the display while ensuring satisfactory stereoscopic display performance, the display may have stereoscopic zones and non-stereoscopic zones. A central stereoscopic zone may be interposed between first and second non-stereoscopic zones. The non-stereoscopic zones may have more curvature than the stereoscopic zone. To prevent crosstalk within the lenticular display, a louver film may be incorporated into the display. The pixel array may have a diagonal layout and may be covered by vertically oriented lenticular lenses.

The opaque walls may control the emission angle of light from the display, reducing crosstalk. The louver film may be interposed between the lenticular lens film and the display panel.

Abstract: One embodiment describes an electronic display that displays image frames with a first refresh rate or a second refresh rate, in which the second refresh rate is lower than the first refresh rate; a display driver that writes the image frames by applying voltage to a display panel; and a timing controller that receives first image data from an image source, in which the first image data describes a first image frame and a first desired refresh rate equal to the second fresh rate; and that instructs the display driver to apply a first set of voltage polarities to the display panel to display first image frame at the first refresh rate and to apply a second set of voltage polarities to the display the first image frame at the second refresh rate when polarity of inversion imbalance accumulated is equal to polarity of the first set of voltage polarities.

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: An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. A plurality of lenticular lenses may extend across the length of the display. The lenticular lenses may be configured to enable stereoscopic viewing of the display such that a viewer perceives three-dimensional images. The display may have a number of independently controllable viewing zones. The viewer may be particularly susceptible to artifacts caused by crosstalk at the edge viewing zones within the primary field of view of the display. Certain types of content may also be more vulnerable to crosstalk than other types of content. Therefore, to mitigate crosstalk artifacts, the pixel value for each pixel may be adjusted based on the viewing zone of the respective pixel and content information (such as texture information or brightness information) associated with the respective pixel.

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.

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 have a number of independently controllable viewing zones. A eye and/or head tracking system may use a camera to capture images of a viewer of the display. Control circuitry in the electronic device may use the captured images from the eye and/or head tracking system to determine which viewing zones are occupied by the viewer's eyes. The control circuitry may disable or dim viewing zones that are not occupied by the viewer's eyes in order to conserve power. An unoccupied viewing zone and an adjacent, occupied viewing zone may display the same image to increase sharpness in the display.
