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.

Abstract: Luminaires and luminaire components are provided that may include emissive, index-matching, and/or outcoupling components that are replaceable separately from other components of the luminaire. In some embodiments, an index-matching component may include a gel sheet or pad that can be disposed between an emissive component and an outcoupling component. The index-matching component may be replaceable separately from the emissive and outcoupling components. In some embodiments, an emissive component including an OLED panel and/or an index-matching component may be replaceable separately from other components of the luminaire.

Abstract: OLED structures including an internal extraction layer are provided. The internal extraction layer includes a material having a refractive index that is higher than the refractive index of a transparent electrode in the device, and a non-planar interface disposed between the material and the substrate. Devices are also provided that include an external extraction layer having a non-planar surface which, when used in conjunction with an internal extraction layer, provides greatly improved outcoupling of light generated by the device.

Abstract: A flexible AMOLED display is disclosed including an OLED stack having an anode layer, a cathode layer and an organic light emitting layer between the anode layer and the cathode layer. A backplane includes a substrate, a plurality of bus lines, and a thin film transistor array. A permeation barrier layer is positioned between the OLED stack and the backplane, and a plurality of vias connect the OLED anode layer to the backplane thin film transistor array. In one embodiment, a neutral plane of the AMOLED display crosses the permeation barrier. In one embodiment, the thickness of at least a portion of the bus lines is greater than the thickness of the cathode layer. A method of increasing the flexibility of an AMOLED display is disclosed. A method of assembling a flexible AMOLED display under a processing temperature of less than 200 degrees Celsius is also disclosed.
