  • Patent number: 11990499
    Abstract: A display apparatus including at least one driving circuit board, a plurality of light-emitting units, and a light-shielding layer is provided. The light-emitting units are disposed on a surface of the at least one driving circuit board and respectively have a plurality of pixel areas. The light-shielding layer is disposed on the at least one driving circuit board and disposed between the light-emitting units. The light-emitting units each have a circuit layer and a plurality of micro light-emitting devices. The circuit layer is electrically bonded to one of the at least one driving circuit board. The plurality of micro light-emitting devices are disposed on a side of the circuit layer away from the at least one driving circuit board and electrically bonded to the circuit layer. The micro light-emitting devices are respectively located in the pixel areas. A method of fabricating the display apparatus is also provided.

  • Publication number: 20210041362
    Abstract: The present invention relates to a fluorescent polymer cast on the surface of wells of a plate and a plate comprising the fluorescent polymer. The plate is used in a method for calibrating read-out values of plate readers. The method for calibrating the plate readers can effectively reduce the deviation of read-out values among different plate readers.

  • Publication number: 20120232185
    Abstract: A biodegradable polymer and its manufacturing method are disclosed. The biodegradable polymer comprises high molecular weight polymer and degradation enhancing polymeric additive. The degradation enhancing polymeric additive is a low molecular weight poly-3-hydroxybutyrate that has a weight-average molecular weight in the range of 50˜2500 g/mole and it can occupies 5%˜30% of the total weight percentage of the biodegradable polymer. The biodegradable polymer and the method for manufacturing the same produce unsaturated compounds of crotonic acid oligomer, which is a low molecular weight poly-3-hydroxybutyrate used as a degradation enhancing polymeric additive, through the degradation process of PHB material and then blend it into high molecular weight polymer. By using its property of easily being degraded by bacteria, the biodegradability and bio-compatibility of the general high molecular weight polymer can be improved.

  • Publication number: 20080293894
    Abstract: The present invention discloses a method of improving the thermal stability of poly-3-hydroxybutyrate (PHB). The thermal stability of PHB was improved by grafting maleic anhydride (MA) onto the PHB through various processes. It has been proved that purified grafted PHB had a higher degradation temperature, a better thermal stability than the pristine PHB, and was not easy to decrease molecular weight by heat treatment. At the same time, the crystallization rate, the melting temperature and crystallinity were all increased. The MA was effectively grafted onto PHB by processes of solution grafting, melt grafting, mechanical grafting methods and so on. The grafting degree of MA was changed with the increasing amounts of the initiator and MA. The degradation temperature of the PHB was significantly increased by MA grafting because the degradation was blocked in the formation of six-member ring by the steric hindrance of the grafted MA.
