PCb08 反射型LCDの評価方法

抄録

Several methods have been utilized to measure the reflectance of reflective type liquid crystal display (LCD). They can be classified into two main types, one is the measurement method using the parallel light source, the other is one using the diffused light source. In this work, we measured the reflectance of various types of reflectors by using two methods mentioned above. The results of both measurements lead to that the former reflects the scattering characteristic, the latter reflects the efficiency of reflective light. These characteristics are important factors for the reflective type LCD. Therefore we have proposed new measurement method using weighted and diffused light source in order to evaluate the scattering characteristic and the efficiency of reflective light at the same time.
