Abstract: A novel thin film encapsulated OLED panel architecture and a method for making the panels with improved shelf life is disclosed. The OLED panel consists of a plurality of OLED pixels; each OLED pixel is individually hermetically sealed and isolated from its neighboring pixels. The organic stack of the OLED pixel is contained within its own hermetically sealed structure, achieved by making the structure on a barrier coated substrate and using a first barrier material as the grid and a second barrier for encapsulating the entire OLED pixel. The first barrier material provides the edge seal while the second barrier disposed over the pixel provides protection from top down moisture diffusion. By isolating and hermetically sealing individual pixels; any damage such as moisture and oxygen ingress due to defects or particles, delamination, cracking etc. can be effectively contained within the pixel thereby protecting other pixels in the panel.

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: 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: Systems and methods for the design and fabrication of OLEDs, including high-performance large-area OLEDs, are provided. Variously described fabrication processes may be used to deposit and pattern bus lines with a smooth profile and a gradual sidewall transition. Such smooth profiles may, for example, reduce the probability of electrical shorting at the bus lines. Accordingly, in certain circumstances, an insulating layer may no longer be considered essential, and may be optionally avoided altogether. In cases where an insulating layer is not used, further enhancements in the emissive area and shelf life of the device may be achieved as well. According to aspects of the invention, bus lines such as those described herein may be deposited, and patterned, using vapor deposition such as vacuum thermal evaporation (VTE) through a shadow mask, and may avoid multiple photolithography steps. Other vapor deposition systems and methods may include, among others, sputter deposition, e-beam evaporation and chemical vapor deposition (CVD). A final profile of the bus line may substantially correspond to the profile as deposited.

Abstract: A wearable, ruggedized device incorporating an OLED display is provided. The device is capable of operating in multiple modes, such as a lower-brightness and/or higher-contrast mode. The use of multiple modes allows for reduced power requirements, while providing responsiveness and continuous availability of the device to a user.

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.
