Abstract

본 발명은 칼라표시장치에 관한 것으로, 일반적으로 콜레스테릭(Cholesteric)액정은 평면(planar)상태에서 피치(pitch)x굴절율의 크기를 파장으로 갖는 빛을 반사시키고 나머지는 투과시킨다. 따라서 종래에는 1장의 판넬에서는 단색(single color)만을 얻을 수 있어 실제의 칼라(color)를 얻으려면 3장의 판넬을 사용하여 각 칼라에 대한 반사된 빛을 얻어 더하거나, 각각의 파장의 빛을 빼주어 여러 색을 표현해 주므로 칼라표면이 어려운 문제점이 있었다. 본 발명은 이러한 문제점을 해결하기 위하여 반사되는 파장의 빛이 피치(pitch) x굴절율에 따라 변화한다는 점과 온도에 따라 피치(pitch)가 변화한다는 점을 이용하여 콜레스테릭 액정의 각 픽셀부분에 따라 온도를 바꾸어줌으로써 반사되는 파장의 빛이 달라져 원하는 칼라를 구현할 수 있도록 하는 칼라표시장치를 제공토록 하는 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color display device, wherein a cholesteric liquid crystal generally reflects light having a wavelength of pitch x refractive index in a planar state and transmits the rest. Therefore, conventionally, only one color can be obtained from one panel. To obtain the actual color, three panels are used to obtain reflected light for each color, or subtract the light of each wavelength. The color surface is difficult because it represents a variety of colors. In order to solve this problem, the present invention utilizes the fact that the light of the reflected wavelength changes according to the pitch x refractive index and that the pitch changes according to the temperature. By changing the temperature according to the change in the light of the reflected wavelength is to provide a color display device that can implement the desired color.
