| Abstract: | By analysing the factors that affect the contrast ratio of a LCD,a new method based on the propagation properties of polarized light in NT-type Liquid crystal to improve the contrast ratio of a LCTV spatial light modulator has been proposed in this paper. The condition of optimum contrast rario was determined experimentally and the contrast ratio was improved from 4:1 to 19:1 |
