  • Patent number: 10655064
    Abstract: The present invention provides a novel liquid crystal material composition comprising one or more compound, in order to achieve the properties of low viscosity, high resistivity, good low-temperature mutual solubility, fast response, excellent transmission, and which can be used for a variety of fast response display modes. Since the working temperature of a LCD material is subjected to the temperature range of individual LC molecules, information can only be displayed in a specific temperature range of the specific liquid crystal macro-alignment phase. At low temperature, the viscosity of liquid crystal increases exponentially, which in turn substantially reduces the response speed and overall performances of the display system.

  • Patent number: 10642157
    Abstract: A method for processing a photosensitive flexographic printing plate having an aqueous-processable photopolymer. A main processing unit is used to develop a relief image by removing unexposed photopolymer using an aqueous processing solution including a first dispersing agent while the photosensitive flexographic printing plate is being subjected to mechanical cleaning. Used aqueous processing solution containing the removed photopolymer is returned back into a processing solution tank. A secondary processing unit is used to wash the developed relief image with secondary aqueous processing solution including a second dispersing agent to remove debris from the developed relief image. Used secondary aqueous processing solution containing the removed photopolymer is directed into the processing solution tank. A portion of the aqueous processing solution from the processing solution tank is removed to keep a volume of aqueous processing solution in the processing solution tank below a predefined maximum volume.
