Abstract: Arrangements of pixel components that allow for full-color devices, while using emissive devices that use blue color altering layers in conjunction with blue emissive regions, that emit at not more than two colors, and/or that use limited number of color altering layers, are provided. Devices disclosed herein also may be achieved using simplified fabrication techniques compared to conventional side-by-side arrangements, because fewer masking steps may be required.

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: A hybrid pixel arrangement for a full-color display is provided, which includes an inorganic LED in at least one sub-pixel, and an organic emissive stack in at least one other sub-pixel. In an embodiment, a first sub-pixel is configured to emit a first color, and includes an inorganic LED, a second sub-pixel is configured to emit a second color, and includes a first organic emissive stack configured to emit an initial color different from the first color. A third sub-pixel is configured to emit a third color different from the initial color.

Abstract: 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.
