  • Patent number: 11512253
    Abstract: A method for fabricating quantum dots according to the present disclosure includes (a) synthesizing InP cores based on an aminophosphine type phosphorus (P) precursor, (b) size-sorting the InP cores, and (c) forming at least two shells on the size-sorted InP cores. In this instance, the size-sorting includes precipitating the InP cores with an addition of a dispersive solvent and a nondispersive solvent to the InP cores and separating the InP cores using a centrifugal separator, wherein the InP cores are separated in a descending order by size by performing iteration with a gradual increase in an amount of the nondispersive solvent.

  • Patent number: 11054957
    Abstract: Disclosed is a touch display device capable of reducing deterioration in touch performance. The touch display device includes a plurality of first touch electrodes disposed in an active area of a substrate and a plurality of second touch electrodes disposed in the active area of the substrate, the plurality of second touch electrodes having different shapes from the plurality of first touch electrodes, wherein at least one of the plurality of second touch electrodes is formed by connecting at least two sub-electrodes having smaller areas than each of the first touch electrodes to each other. Consequently, the areas of the first and second touch electrodes are similar to each other, whereby it is possible to reduce touch performance deteriorated due to deviation in area between the touch electrodes.

  • Patent number: 7959989
    Abstract: The present invention relates to a novel cyclic olefin compound, a polymer including the cyclic olefin compound, a liquid crystal alignment film including the polymer, and a liquid crystal display device including the liquid crystal alignment film. Since the polymer includes the cyclic olefin compound as a main chain, the thermal stability is excellent and the photoreactive speed is high. Accordingly, the production time can be reduced, the production cost can be reduced, and the anchoring force of the liquid crystal can be increased because the alignment property is stabilized due to the curing.

  • Publication number: 20100060834
    Abstract: The present invention relates to a novel polyimide copolymer, a method of preparing the polyimide copolymer, a liquid crystal aligning layer including the polyimide copolymer, a method of producing the liquid crystal aligning layer, and a liquid crystal display including the liquid crystal aligning layer. The liquid crystal aligning layer that includes the polyimide copolymer according to the present invention is advantageous in that when ultraviolet rays are radiated on movable chains of the polyamic acid copolymer to perform alignment before a polyimide copolymer is imidized and heat treatment is then performed to conduct imidization, thermal stability is excellent, residual images are not formed, and alignment of liquid crystals is excellent.
