Abstract: Examples are disclosed that relate to backlit electronic displays that may help to avoid apparent non-uniform image brightness across a displayed image. One example provides an electronic display comprising a light guide, an image-forming layer, and a light-steering layer. The light guide is configured to release light over a display area. The image-forming layer is configured to form a display image by modulating the light released by the light guide. The light-steering layer is configured to steer together the light released from a peripheral region of the light guide and the light released from a central region of the light guide.

Abstract: A reflective multi-layer structure forms an external surface of an electronic device and includes a light-emitting display separated from the external surface by a dielectric polarizing film and a diffuser. Light emitted by the light-emitting display is transmitted sequentially through the dielectric polarizing film and the diffuser to present information on the external surface.

Abstract: The described implementations relate to enhancement images, such as in videoconferencing scenarios. One system includes a poriferous display screen having generally opposing front and back surfaces. This system also includes a camera positioned proximate to the back surface to capture an image through the poriferous display screen.

Abstract: The present disclosure relates identifying an intended viewer and an unintended viewer of a liquid crystal display (LCD) using face recognition technology. Once identified the system may determine a face position for the unintended viewer. The system may modulate the voltage applied at a third electrode on the color filter layer of the LCD to achieve a certain off-axis contrast that may reduce the unintended viewer's visibility of the LCD without restricting the visibility of the intended viewer. Ultimately, the present disclosure provides enhanced privacy options for the intended viewer with a lightweight, inexpensive, and highly transportable system.

Abstract: Methods, systems and computer program products are provided for a logo camera. Camera thickness may be reduced using multiple lenses and sensors. A fixed or variable color icon may provide a function, notice or privacy warning, convey information, and/or serve decorative and/or other purposes. Color filters may be fixed or variable. A color icon may be created, for example, by controlling the colors of display pixels aligned with optical paths of camera lens and sensor arrays. Colors in an icon may provide color filters corresponding to an array of lenses that focus color-separated light on one or more camera sensors. Sensors may be optimized for particular colors. Color-separated images may be combined into a single image. Lens and camera sensor arrays may be compatible with multiple logos or other icon images. Cameras behind fixed or variable color icons may be concealed, for example, using shutters or semi-reflective layers.

Abstract: A touch screen panel comprises an outer surface that defines a touch sensitive surface with a touch sensitive area. The outer surface comprises friction features distributed throughout at least a portion of the touch sensitive area according to one or more predetermined spacings. The friction features are configured to have predetermined friction characteristics that impart a desired tactile effect, e.g., a paper-like feel, to the touch sensitive surface when contacted by a user's finger or a stylus. Methods of forming a touch screen panel with predetermined friction features are also described.
