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: Methods of operation and devices are provided in which the operation of a full-color display is modified based upon historical luminance data that indicates an intensity at which at least one sub-pixel of the device is driven over a period of time. An expected degradation level of one or more pixel elements in the device is calculated based upon the luminance data, and video signals received by the device are modified based upon the expected degradation level to reduce image sticking and/or other undesirable effects in the device.

Abstract: A display includes one or more organic light emitting device panels. Each organic light emitting device panel has an array of single-color subpixel areas of different colors extending over an active area thereof arranged in a predetermined pattern by color. At least one of the subpixel areas in the predetermined pattern that would otherwise be designated as a subpixel area through which blue light is emitted based on a position thereof in the predetermined pattern being predetermined to be non-emissive. A volume of the organic light emitting device panel associated with the at least one predetermined non-emissive subpixel area is non-emissive and includes a via or a functional electronic component therein.

Abstract: A selective organic emissive material deposition technique is disclosed. A charged organic emissive material may be mixed with a carrier gas and ejected towards a charged intended area of a substrate. The charge for the emissive material may be such that the organic emissive material is attracted to the charged intended area of the substrate and, accordingly, deposited selectively over the charged intended area of the substrate. Additionally, surrounding unintended areas of the substrate may be charged such that the charged organic emissive material is repelled by the unintended areas.

Abstract: Embodiments of the disclosed subject matter provide systems and methods of depositing a film on a selective area of a substrate. A first jet of a first material may be ejected from a first nozzle assembly of a jet head having a plurality of nozzle assemblies to form a first portion of a film deposition on the substrate. A second jet of a second material may be ejected from a second nozzle assembly of the plurality of nozzle assemblies, the second nozzle assembly being aligned with the first nozzle assembly parallel to a direction of motion between the plurality of nozzle assemblies and the substrate, and the second material being different than the first material. The second material may react with the first portion of the film deposition to form a composite film deposition on the substrate when using reactive gas precursors.

Abstract: Embodiments of the disclosed subject matter provide a device having a substrate, at least one organic light-emitting layer disposed over the substrate, and at least one down-conversion layer. The at least one down-conversion layer may generate the NIR emission by absorbing at least a portion of the light emitted by the at least one organic light emitting layer, and re-emitting light at a longer NIR wavelength or range of wavelengths having a peak NIR emission that may be greater than 700 nm, greater than 750 nm, or greater than 800 nm. An out-of-plane optical density of the at least one down-conversion layer may be less than 0.1 for all wavelengths of light in a range from 400 nm to 600 nm.
