摘要

介绍了聚合物分散液晶、剪切液晶、散射偏振器和透射投影屏的概念。制备了剪切型液晶散射偏光玻璃样品。样品由两片玻璃组成，在紫外固化过程中，随着剪切应力的增加，形成一层聚合物分散液晶膜。给出了偏振照片以及偏振光透过率和雾度随光轴角度的曲线。实验结果表明，该材料呈半透明状，具有光轴。将散射偏光片与吸收偏光片相结合，给出了一种新型的光可调功能窗，并将该玻璃与1LCD投影机或1LCOS投影机相结合，得到了用于背投显示系统的具有良好成像效果的透射式投影屏。

Preparation and application of sheared liquid crystal scattering polarizer glass

The concepts of polymer dispersed liquid crystal、sheared liquid crystal、scattering polarizer and transmitting projection screen are introduced.The samples of sheared liquid crystal scattering polarizer glass are prepared.The sample consisted of tow piece of glass and a layer of polymer dispersed liquid crystal film is formed during the UV solidification process while the shear stress added.The polarizing photograph and the curves of polarizing light transmissivity and haze with angle of light axis are given.The experimental results show that it looks translucent and there is light axis.To combine the scattering polarizer glass with absorbing polarizer,a new kind of light tunable function window is given,and to combine the glass with 1LCD projector or 1LCOS projector,the transmitting projection screen is obtained with excellent imaged effect for rear projection display system.

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
