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.

Organic electroluminescent devices

Hermetically sealed isolated OLED pixels

A first product as disclosed herein includes multiple devices, such as OLEDs, which are moveably connected to one another. The devices may be moveable from a first position in which they are stacked, closed, rolled, or the like, to a second expanded position in which they may be usable together as a single device. Active areas of the devices may be disposed within 3 mm from each adjacent or included active area when the device is in the first position, the second position, or both. Each active device may include a barrier film that covers at least a portion of the substrate and/or the active area of one or more of the devices.

Electronic device with reduced non-device edge area

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.

Intelligent dimming lighting

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.

Luminaire and individually replaceable components

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.

OLED lighting device with short tolerant structure

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.

Macro-image OLED lighting system

Systems and methods for fabricating an OLED are provided, which include dispensing a substrate material onto a substrate carrier, the substrate carrier being rotated by one or more drums, curing the substrate material to form a substrate, depositing at least one OLED onto the substrate, and separating the substrate from the substrate carrier.

Methods for fabricating OLEDs

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.

Organic light emitting device (OLED) panel of arbitrary shape

A light unit is provided that includes a frame having a top face and a bottom face, with the bottom face at least partially overlapping the top face in some configurations. A non-OLED light source is disposed on the top face and configured to emit light away from the top face. An OLED light source is disposed on the bottom face and configured to emit light away from the bottom face.
