Abstract: A high-resolution, Active Matrix (AM) programmed monolithic Light Emitting Diode (LED) micro-array is fabricated using flip-chip technology. The fabrication process includes fabrications of an LED micro-array and an AM panel, and combining the resulting LED micro-array and AM panel using the flip-chip technology. The LED micro-array is grown and fabricated on a sapphire substrate and the AM panel can be fabricated using PMOS process, NMOS process, or CMOS process. LED pixels in a same row share a common N-bus line that is connected to the ground of AM panel while p-electrodes of the LED pixels are electrically separated such that each p-electrode is independently connected to an output of drive circuits mounted on the AM panel. The LED micro-array is flip-chip bonded to the AM panel so that the AM panel controls the LED pixels individually and the LED pixels exhibit excellent emission uniformity.

Abstract: A time-temperature indicator (TTI) uses polymer hardening properties to “set” or retain indications of temperature history. The TTI includes a mesh layer affixed to a thermo-conductive adhesive layer and a photonic crystal patterned film affixed to the mesh layer. The photonic crystal shows a property of bandgap shift vs temperature and responds to a predetermined range of temperatures to provide a visible indication of the range of temperatures. A hardener pouch is affixed to one end of the mesh layer and releases hardener in response to an initiating event, so that the photonic crystal material responds to the hardener by presenting a fixed state.
