This technology is a new microarray chip sensing technology that integrates "organic light-emitting diodes", "liquid crystal chemical sensors" and "mobile communication system" into "multifunctional liquid crystal smart cloud sensors". The obtained signals are uploaded to the cloud for multi-dimensional analysis to achieve multiplex detection in one single sample. This sensor device is lightweight, low-cost, simple to operate, and the target-of-interest can be custom-made according to user needs.

A new emission model of organic light-emitting diode (OLED) based on triplet-triplet annihilation upconversion (TTAUC) with a high intrinsic upconversion efficiency (86.1) by using tris-(8-hydroxyquinoline)aluminum (Alq3)9,10-Bis(2-naphthyl)anthracene (ADN) as green sensitizerblue emitter, respectively. This structure improved the device efficiencyoperation lifetime compared to the conventional TTA-OLEDs. A record-high efficiency of 15.4EQEa 1.5x lifetime performance comparing to the commercial blue OLED are obtained by utilizing the TTAUC mechanism.
