Abstract:
OLED panels and techniques for fabricating OLED panels are provided. Multiple cuts may be made in an OLED panel to define a desired shape, as well as the location and shape of external electrical contacts. The panel may be encapsulated before or after being cut to a desired shape, allowing for greater flexibility and efficiency during manufacture.
Abstract:
Described herein are systems, devices, and methods related to adjusting the intensity of specific wavelengths in an illumination panel based on the presence of a person near the panel. By reducing some emitted wavelengths, such as wavelengths associated with blue light, when such wavelengths are not needed or desired, the lifetime and/or efficiency of the lighting panel can be increased. The systems, devices, and methods can be used to reduce energy costs and also to delay the aging of lighting panels.
Abstract:
Devices and techniques are provided in which a transparent substrate is scored to provide a non-planar surface on one side of the substrate. An OLED is then disposed on the other side of the scored substrate and optically coupled to the substrate. The scored surface provides improvements to outcoupling of light generated by the OLED, with little or no additional thickness relative to the OLED alone.
Abstract:
Devices are provided that include a flexible OLED panel and a connection between points of the flexible OLED panel that causes the flexible OLED panel to be disposed in a non-planar configuration. Alternatively or in addition, the connection may be a flexible component connected to the flexible OLED panel, which is configured to maintain the flexible OLED panel in the non-planar shape.
Abstract:
OLEDs and techniques for fabricating OLEDs are provided, in which the OLED has a shortest lateral current path through an active region that is longer than the shortest lateral electric field line within the active region. Such configurations prevent “hot spots” in the OLED panel, leading to a more uniform emission by the panel.
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:
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:
The device consists of measuring aspects of human activity or emotion and then communicating that information to an adjustable lighting device or electronic display (as part of a phone, tablet, computer etc) such that the color temperature (or luminance) of the display or lamp is adjusted to match the mood of the user e.g. warmer in the evening close to the end of the day, and cooler in the morning for productivity.

Abstract:
A transparent emissive device is provided. The device may include one or more OLEDs having an anode, a cathode, and an organic emissive layer disposed between the anode and the cathode. In some configurations, the OLEDs may be non-transparent. The device may also include one or more locally transparent regions, which, in combination with the non-transparent OLEDs, provides an overall device transparency of 5% or more.
