    Abstract: An array of pixels in a display may be illuminated by a backlight having an array of light-emitting diodes in an array of respective cells. A reflector is used to reflect light from the light-emitting diodes through the array of pixels. Within the cells, the reflector has cross-sectional profiles that help distribute light emitted from the light-emitting diodes toward edges of the cells. A light diffuser layer for the backlight may have a partially reflective layer such as a thin-film interference filter with an angularly dependent transmission. Within each cell, the reflector may have cross-sectional profiles with portions that are parabolic or elliptical.

    Abstract: An electronic device may include a display. The display includes display driver circuitry for driving data lines routed across the display. The electronic device may have a recessed device housing region, where at least some of the data lines are routed around the recessed region. The data lines being routed around the recessed region may be formed in at least two different metal routing layers. The electronic device may further include additional display driver circuitry for driving data lines from another peripheral housing edge to obviate the need to route around the recessed region. The data lines from the two display driver circuitries can be disconnected at random locations or can be interlaced to achieve spatial interleaving. The display driver circuitry may include demultiplexing circuitry having smaller switches coupled in parallel with larger demultiplexer routing switches to reduce voltage kick and charge injection.

    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 louver film may have a plurality of transparent portions separated by opaque walls. 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: A display may have a backlight unit that provides backlight illumination. The backlight unit may include a light guide that distributes light through the display. The light guide may include opposing first and second edges. A first light source such as a first row of light-emitting diodes may emit light into the first edge and a second light source such as a second row of light-emitting diodes may emit light into the second edge. In a normal viewing mode, both light sources are active and backlight illumination is provided over a normal range of angles. In a restricted angle-of-view mode, only one light source is active and backlight is emitted in a more concentrated fashion over a restricted range of angles. In a high luminance restricted angle-of-view mode, the active light source is driven at an elevated level.

    Abstract translation: 显示器可以具有提供背光照明的背光单元。 背光单元可以包括通过显示器分配光的光导。 光导可以包括相对的第一和第二边缘。 诸如第一排发光二极管的第一光源可以将光发射到第一边缘中，并且诸如第二排发光二极管的第二光源可以将光发射到第二边缘。 在正常观看模式下，两个光源都是有效的，并且在正常的角度范围内提供背光照明。 在受限制的视角模式中，只有一个光源处于活动状态，并且在限制的角度范围内以更集中的方式发射背光。 在高亮度限制视角模式中，主动光源以升高的水平被驱动。

    Abstract: An electronic device may include a stereoscopic display that is configured to display three-dimensional content for a viewer. The stereoscopic display may include a lenticular lens film with lenticular lenses that extend across the length of the display and may be referred to as a lenticular display. The lenticular display may have convex curvature. The lenticular display may include a color filter layer with color filters and an opaque masking layer. The color filter layer may be interposed between the lenticular lens film and an array of display pixels for the display. The color filter layer may mitigate ghost image artifacts and reflections of ambient light. Microlenses may be included between the lenticular lens film and the array of display pixels to improve the efficiency of the display. The display may include a Fresnel lens layer. The lenticular lens film may include lenticular lenses having different shapes.
