  • Publication number: 20200012037
    Abstract: A display device includes a display panel. A light source is configured to output light having a first color. A light guide plate is disposed below the display panel and includes an incident surface into which the first color light is incident, an opposite surface that is opposite to the incident surface, and an emission surface facing the display panel. A color convertor is disposed between the display panel and the light guide plate. The color convertor is configured to absorb the first color light and to output light having a different color to the display panel. A reflector is disposed below the light guide plate. A first reflection area and an adjacent second reflection area are defined on the reflector. A light absorber is disposed on the first reflection area adjacent to the light source. The light absorber is configured to absorb the first color light.

  • Patent number: 9505777
    Abstract: The present invention relates to a method for preparing anhydrous sugar alcohol, and more particularly, to a cheap and highly efficient method for preparing anhydrous sugar alcohol having a high final purity of at least 99%, and having good ion content, pH, conductivity, and color properties. According to the method, a hydrogenated sugar is dehydrated so as to be transformed into anhydrous sugar alcohol, and a series of processes including distillation, crystallization, decoloration, and ion exchange resin treatment are conducted.

  • Patent number: 9399212
    Abstract: The present invention relates to a method for producing an anhydrosugar alcohol and, more specifically, to a method for producing an anhydrosugar alcohol which, when the step of subjecting a hydrogenated sugar to a dehydration reaction in a reactor so as to convert same to an anhydrosugar alcohol is performed, allows the hydrogenated sugar to be continuously introduced into the reactor and the produced anhydrosugar alcohol to be continuously discharged out of the reactor while the dehydration reaction is carried out, also prevents a reaction mixture from circulating inside and outside the reactor while the dehydration reaction is carried out, and thereby can significantly improve production efficiency compared with a conventional process adopting a batch or semi-batch-type dehydration reaction and thus can be appropriately applied particularly to a large-scale anhydrosugar alcohol production process.

  • Patent number: 9260447
    Abstract: The present invention relates to a technique for preparing an anhydrosugar alcohol using hydrogenated sugar as a raw material and, more specifically, to a technique for preparing a high-purity anhydrosugar alcohol by adding an acid to hydrogenated sugar (for example, hexitol) to convert same to an anhydrosugar alcohol, then distilling the converted liquid, and crystallizing the distilled liquid in a solvent, the technique removing a crystallization solvent from a crystallization mother liquor generated during a crystallization step and then introducing the resultant product together with the distilled liquid and the converted liquid into a distillation step, thereby being capable of improving the total distillation yield of the anhydrosugar alcohol, improving distillation efficiency by improving the mobility of a distillate, and further reducing the amount of generated waste and treatment costs and thus highly efficiently preparing the high-purity anhydrosugar alcohol at reduced costs.

  • Publication number: 20150329448
    Abstract: The present invention relates to a method for preparing an anhydrosugar alcohol using hydrol (namely, a crystalline mother liquor remaining after obtaining crystalline glucose from a crude glucose liquor). More particularly, the present invention relates to a method for preparing an anhydrosugar alcohol in a method for performing a dehydration reaction on the hydrogenated sugar so as to convert the hydrogenated sugar to an anhydrosugar alcohol, wherein the method for preparing an anhydrosugar alcohol is configured to use, as at least a portion of the hydrogenated sugar, the product obtained from the hydrogenation of the hydrol which is a by-product or waste generated during the production of glucose, thus relatively lowering the cost for a material as compared with a case of using a high purity raw material (for example, high purity sorbitol), to thus improve economical advantages, and further reduce the amount of waste and cost for disposal of the waste during the production of glucose.
