Abstract: Described herein are devices and methods related to fabrication of organic electroluminescent devices and related components. In certain embodiments, devices and methods for fabricating OLED panels on substrates with non-uniform reflection or un-even surfaces require that the non-uniform features are arranged in a way such that they are not presented in the region where photolithography features are needed. In certain embodiments, where precision processing such as photolithography features are needed, the substrate is designed to be flat.

Abstract: A method of forming microelectronic systems on a flexible substrate includes depositing a plurality of layers on one side of the flexible substrate. Each of the plurality of layers is deposited from one of a plurality of sources. A vertical projection of a perimeter of each one of the plurality of sources does not intersect the flexible substrate. The flexible substrate is in motion during the depositing the plurality of layers via a roll to roll feed and retrieval system.

Abstract: A flexible multilayer scattering substrate is disclosed. Built on a flexible supporting layer, the multilayer contains one or more scattering layers and other functional layers so that it can extract the trapped light in substrate and waveguide of an OLED. The processing of each layer is fully compatible with large area, flexible OLED manufactory, and by controlling processing conditions of each incorporated layer, the substrate microstructure can be tuned. Topographic features can be created on the top surface of substrate by changing the thickness and properties of the multilayer.

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.
