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: An OLED panel having a plurality of OLED circuit elements is provided. Each OLED circuit element may include a fuse or other component that can be ablated or otherwise opened to render the component essentially non-conductive. Each OLED circuit element may comprise a pixel that may include a first electrode, a second electrode, and an organic electroluminescent (EL) material disposed between the first and the second electrodes. Each of the OLED circuit elements may not be electrically connected in series with any other of the OLED circuit elements.

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.

Abstract: Techniques to fabricate and assemble a lighting system including multiple patterned OLED lighting panels to form a high-resolution macro image are provided. An image to be displayed is determined and divided into multiple portions. Patterned static OLED lighting panels that display each portion of the image are fabricated and assembled into a fixture to form a macro-image lighting system. The fixture may removably receive and hold individual panels, such that each panel may be replaced if any malfunction occurs. Each of the patterned OLED panels may be individually driven through an electrical connection within the fixture so as to be operated at substantially the same brightness and/or same chromaticity.

Abstract: Disclosed is a novel moisture permeation barrier system for substrates and devices and method of making the same. The permeation barrier system includes two barrier layers. The first barrier layer is disposed over the substrate or an electronic device. The second barrier layer is then disposed over the first barrier layer. This system has relatively low permeability to moisture and is flexible. It may cover particles and provide moisture protection with a relatively small width edge seal.
