摘要： Elements are added to a light emitting device to reduce the stress within the light emitting device caused by thermal cycling. Alternatively, or additionally, materials are selected for forming contacts within a light emitting device based on their coefficient of thermal expansion and their relative cost, copper alloys being less expensive than gold, and providing a lower coefficient of thermal expansion than copper. Elements of the light emitting device may also be structured to distribute the stress during thermal cycling.

摘要： Methods of controlling stress in GaN films deposited on silicon and silicon carbide substrates and the films produced therefrom are disclosed. A typical method comprises providing a substrate and depositing a graded gallium nitride layer on the substrate having a varying composition of a substantially continuous grade from an initial composition to a final composition formed from a supply of at least one precursor in a growth chamber without any interruption in the supply. A typical semiconductor film comprises a substrate and a graded gallium nitride layer deposited on the substrate having a varying composition of a substantially continuous grade from an initial composition to a final composition formed from a supply of at least one precursor in a growth chamber without any interruption in the supply.

摘要： A vehicular display that contains a sparse array of light-emitting diodes (LEDs), system, and method of fabrication are disclosed. The vehicular display includes at least one tile disposed in a vehicle to provide a display of internal and external information. Each tile has a transparent flexible substrate, a sparse array of LEDs disposed on the transparent flexible substrate, a rigid substrate adhered to the transparent flexible substrate via an adhesive layer in which the sparse array of LEDs is encapsulated, and a driver disposed on an edge of the tile and configured to drive the LEDs. The LEDs are sparse enough to enable information to be displayed through a vehicle window while still enabling a viewer to see through the window.

摘要： A display that contains a sparse array of light-emitting diodes (LEDs), including a related system and method of fabrication are disclosed. The display includes at least one panel disposed in or on a transparent material to provide a display on one or both sides of the material. Each tile has a transparent flexible substrate, a sparse array of LEDs disposed on the transparent flexible substrate, a rigid substrate adhered to the transparent flexible substrate via an adhesive layer in which the sparse array of LEDs is encapsulated, and a driver disposed on an edge of the tile and configured to drive the LEDs. The LEDs are sparse enough to enable information to be displayed through the transparent material while still enabling a viewer to see through the transparent material.

摘要： A display that contains a sparse array of light-emitting diodes (LEDs), system, and method of fabrication are disclosed. The display includes a panel having at least one tile configured to display information. The panel is disposed within or on a transparent material. Each tile includes an array of LEDs, which have a uniform distance therebetween such that light from the array is viewable on opposing sides of the panel while providing visibility through the panel. A darkening layer on at least one side of the panel provides selectable darkening to block the light from exiting the at least one side of the panel.
