Abstract: A method of making a flexible organic electronic device includes forming a first portion including a first flexible substrate, wherein the first portion is formed under a first set of conditions to provide a barrier system, separately forming a second portion comprising at least one organic electronic device region deposited upon a second flexible substrate, wherein the second portion is formed under a second set of conditions, different from the first set of conditions, and placing the first portion over the second portion (although not necessarily in contact therewith) to cover the organic electronic device region. The organic electronic device region is not placed in physical contact with another solid material before placing the first portion over the second portion.

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: 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: Embodiments of the present invention provide electronic devices such as OLEDs that have enhanced mechanical integrity and prolonged shelf, by minimizing the spread of a delamination region using topographical non-uniformities introduced in the device structure. For example, a device may be made deliberately non-planar by introducing multiple energy barriers which can prevent or minimize the propagation of a delamination, because the delamination will have to cross the energy barriers in order to spread to a larger area.

Abstract: Optical components and devices are provided that include a substrate, a microlens array, and a barrier film system conformally covering the microlens array. An OLED may be optically coupled to the microlens array. The barrier film may provide protection to the microlens array or other components, without having a significant negative impact on outcoupling of light from the coupled OLED by the microlens array.
