Abstract: An electronic device may generate content that is to be displayed on a display. The display may have an array of liquid crystal display pixels for displaying image frames of the content. The display may be operated in at least a normal viewing mode, a privacy mode, an outdoor viewing mode, and a power saving mode. The different view modes may exhibit different viewing angles. In one configuration, the display may include a backlight unit (42) that generates a collimated light source and that includes a switchable diffuser film (200) for selectively scattering the collimated light source depending on the current viewing mode of the display. In another configuration, the display may include a backlight unit that generates a scattered light source that includes a switchable microarray structure such as a switchable mirror structure or a tunable microlens array for selectively collimating the scattered light source depending on the current viewing mode.

Abstract: Common electrodes (Vcom) of integrated touch screens can be segmented into electrically isolated Vcom portions that can be operated as drive lines and/or sense lines of a touch sensing system. The touch screen can include high-resistivity connections between Vcom portions. The resistivity of the high-resistivity connections can be high enough so that touch sensing and image display can be performed by the touch screen, and the high-resistivity connections can provide an added functionality by allowing a charge build up on one of the Vcom portions to be spread to other Vcom portions and/or discharged from system by allowing charge to leak through the high-resistivity connections. In this way, for example, visual artifacts that result from charge build up on a Vcom portion can be reduced or eliminated.

Abstract: An electronic device may have a display such as a liquid crystal display. The display may have multiple layers of material such as a color filter layer and a thin-film transistor layer. An opaque masking layer may be formed on a display layer such as the color filter layer.

Abstract: Updating an image of a display is provided by scanning rows of sub-pixels of the display by applying voltages to pixel electrodes of adjacent sub-pixels in different lines such that polarity changes in opposite directions can occur in two sub-pixels that are adjacent to a particular sub-pixel. In one example, a positive -polarity voltage can be applied to one sub-pixel that is adjacent to a particular sub-pixel, causing a swing in the polarity of the sub-pixel from negative to positive. A negative-polarity voltage can be applied to another sub-pixel that is adjacent to the particular sub-pixel, swinging the polarity of the pixel electrode from positive to negative. A change in brightness of the particular sub-pixel that may result from a voltage swing one direction in an adjacent sub-pixel may be offset by a change in brightness of the particular sub-pixel that may result from a voltage swing in another adjacent sub- pixel.

Abstract: Devices and methods related to high-contrast liquid crystal displays (LCDs) are provided. For example, such an electronic device may include an LCD with two liquid crystal alignment layers not symmetric to one another and upper and lower polarizing layers respectively above and below the alignment layers. Light transmittance through the plurality of pixels may increase monotonically with gray scale voltage. The display may operate using a gray scale level 0 voltage higher than a minimum gray scale level 0 voltage capability of the display. Additionally or alternatively, liquid crystal molecular alignment axes of the two alignment layers may be offset from one another by an angle other than a multiple of 180 degrees. Additionally or alternatively, a first polarizing axis of the upper polarizing layer or a second polarizing axis of the lower polarizing layer, or both, may be neither parallel nor perpendicular to one of the liquid crystal molecular alignment axes.

Abstract: An optical system is described. The optical system may include a sensor which may be in a mobile device. The optical system may use the same light source for imaging the display and for providing light to a sensor or sensor device. The optical system may be configured so that randomly polarized light will exit the device for viewing so that a user may view the display in any rotated orientation while wearing polarized eyewear. The optical system may further be configured to mitigate reflections in the mobile device from ambient light entering the system and from reflected and backscattered light from cross-contaminating the imaging light of the display.
