发明名称 Transmission-type screen for a projection television device.
摘要 <p>A transmission-type video projection television system employs a transmission-type screen for displaying an image projected from a rear projector for visual observation by an observer in front of the screen. The transmission-type screen has Fresnel and lenticular lenses, one of which has an electrically conductlve layer or a metal member on its surface to prevent the lens from being electrostatically charged, so that dust or dirt particles will not be attracted to the screen. &lt;IMAGE&gt;</p>
