Patent number: 10310314Abstract: A display panel includes an array of display pixels to output an image. The array of display pixels includes a central pixel region and a perimeter pixel region. The central pixel region includes central pixel units each having three different colored sub-pixels. The different colored sub-pixels of the central pixel units are organized according to a central layout pattern that repeats across the central pixel region. The perimeter pixel region is disposed along a perimeter of the central pixel region and includes perimeter pixel units that increase a brightness of the image along edges of the central pixel region to mask gaps around the array of display pixels when tiling the array of display pixels with other arrays of display pixels.Type: GrantFiled: August 14, 2015Date of Patent: June 4, 2019Assignee: X Development LLCInventors: Philip E.

Patent number: 9035327Abstract: A multi-chip light emitting device (LED) uses a low-cost carrier structure that facilitates the use of substrates that are optimized to support the devices that require a substrate. Depending upon the type of LED elements used, some of the LED elements may be mounted on the carrier structure, rather than on the more expensive ceramic substrate. In like manner, other devices, such as sensors and control elements, may be mounted on the carrier structure as well. Because the carrier and substrate structures are formed independent of the encapsulation and other after-formation processes, these structures can be tested prior to encapsulation, thereby avoiding the cost of these processes being applied to inoperative structures.Type: GrantFiled: June 28, 2013Date of Patent: May 19, 2015Assignees: Koninklijke Philips Electronics N.V., Philips Lumileds Lighting Company, LLCInventor: Serge J.
