Abstract:
Devices suitable for close illumination of an object are provided. Such a device includes a highly transparent electrode and a highly reflective, weakly transmissive electrode, with other OLED layers disposed between them. During operation in close proximity to an object, the object is illuminated by the device, while still allowing a user to see through the device.
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:
Systems, and methods for the design and fabrication of OLEDs, including large-area OLEDs with metal bus lines, are provided. For a given panel area dimension, target luminous emittance, OLED device structure and efficiency, and electrical resistivity and thickness of the bus line material and electrode onto which the bus lines are disposed, a bus line pattern may be designed to optimize Fill Factor (FF), Luminance Uniformity (U) and Power Loss (PL). Example designs may be to maximize FF, maximize U and minimize PL. or define minimum criteria for U and a maximum criteria for PL, and then to optimize the bus line layout to maximize FF. OLED panels including bus lines with different resistances along the bus line are also described.
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:
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:
Devices and components are provided that include a curved outcoupling component and an OLED, where the outcoupling component provides up to 100% outcoupling of light emitted by the OLED into air. The outcoupling component has an outer radius R and includes a material with a refractive index n. The OLED is in optical communication with the outcoupling component and disposed such that each emissive element of the OLED is within a distance r measured from the center of curvature of the surface at the outer radius R, such that R−r>(n−1)r.

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.
