Abstract: An autostereoscopic display system includes a display including a plurality of addressable pixels. Each of the plurality of pixels includes two or more sub-pixels. The display is adapted to have n views in the horizontal direction wherein n is an integer greater than or equal to 2. A native pixel density of the display in the horizontal direction divided by n is greater than 75% of a native pixel density in the vertical direction. The system further includes a view selector that, for each of two or more viewing perspectives, makes one of the views visible and a multiplexer system in operative connection with the display. The multiplexer system is adapted to controllably shift light horizontally from at least one of the plurality of pixels.

Abstract: The present invention provides an emissive region in organic light emitting devices having a combined emission from at least two emissive materials, a fluorescent blue emissive material and a phosphorescent emissive material. The emissive region may further comprise additional fluorescent or phosphorescent emissive materials. Preferably, the emissive region has three different emissive materials—a red emissive material, a green emissive material and a blue emissive material. Organic light emitting devices incorporating the emissive region provides a high color-stability of the light emission over a wide range of currents or luminances.

Abstract: Systems, devices, and techniques are provided for operating a display and/or an illumination source based upon the direction of a user's gaze and/or a desired illumination level in a monitored area. One or more elements may be controlled with sensor input and application lighting preferences. For example, when a user receives a video call, light may be activated to illuminate their face. When the user is looking at the display, the display will be at the brightness necessary for the lighting conditions. When the user looks away from the screen, the screen may dim further and the lighting elements for the desk can brighten. Similarly, embodiments may adjust the lighting in a monitored location based upon lighting levels identified in other areas.
