Abstract
본 발명은 액정을 이용한 칠판에 관한 것으로서, 좀더 상세히는 네마틱(Nematic)액정, 콜레스테릭(Cholesteric)액정, 그리고 여기에 폴리머(Polymer)를 혼합한 겔(Gel)을 이용한 칠판에 관한 것이다.The present invention relates to a blackboard using liquid crystals, and more particularly, to a blackboard using a nematic liquid crystal, a cholesteric liquid crystal, and a gel in which a polymer is mixed.
본 발명의 LC/Polymer Gel을 이용한 칠판은 보드(Board)와 전원장치를 구비하는 칠판에 있어서, 상기 보드는 상,하면 각각 플랙시블 투명필름이 위치하고, 그 투명필림의 각 내표면에는 ITO(Indium Tin Oxide)막이 도포되어 있으며, 상기 상,하면의 투명필름 사이에는 네마틱(Nematic)액정, 콜레스테릭(Cholesteric)액정, 폴리머(Polymer)의 혼합체 겔(Gel)이 충전(充塡)되어있고; 상기 전원장치에는 가변 전압조정 장치가 내장되어 있는 것에 그 특징이 있다.In the blackboard using LC / Polymer Gel of the present invention, a board comprising a board and a power supply device, wherein the board is provided with a flexible transparent film on the upper and lower surfaces, and each inner surface of the transparent film is ITO (Indium). Tin Oxide film is applied, and Nematic liquid crystal, cholesteric liquid crystal, and polymer mixed gel are filled between the upper and lower transparent films. ; The power supply device is characterized in that the variable voltage adjustment device is built-in.
이러한 구조적 특성을 가진 본 발명의 LC/Polymer Gel을 이용한 칠판은 종래의 흑판이나 백보드에 비해, 그 사용상의 편리한 기능으로 인해 제품의 시장 경쟁력에서 대단한 호평을 받게 될 것이다.The blackboard using the LC / Polymer Gel of the present invention having such structural characteristics will be greatly favored in the market competitiveness of the product due to its convenient function compared to the conventional blackboard or white board.
