摘要： 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.

摘要： A flexible AMOLED display is disclosed including an OLED stack having an anode layer, a cathode layer and an organic light emitting layer between the anode layer and the cathode layer. A backplane includes a substrate, a plurality of bus lines, and a thin film transistor array. A permeation barrier layer is positioned between the OLED stack and the backplane, and a plurality of vias connect the OLED anode layer to the backplane thin film transistor array. In one embodiment, a neutral plane of the AMOLED display crosses the permeation barrier. In one embodiment, the thickness of at least a portion of the bus lines is greater than the thickness of the cathode layer. A method of increasing the flexibility of an AMOLED display is disclosed. A method of assembling a flexible AMOLED display under a processing temperature of less than 200 degrees Celsius is also disclosed.

摘要： Devices and techniques for fabricating such devices are provided, which include an optical system having a combined permeation barrier and circular polarizer. The optical system is relatively thin and flexible, thereby allowing for OLED displays and similar devices that reduce glare while being suitable for use in flexible displays and similar devices.

摘要： 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.
