摘要: A plurality of liquid crystal modules is vertically and horizontally arranged, each of which is supplied light by a light source via optical fibers. A screen can be wound up at a cabinet. An image from each of the plurality of liquid crystal modules does not interfere one another because a light shielding board is installed.
摘要翻译: 垂直和水平布置多个液晶模块,每个液晶模块通过光纤由光源供给光。 屏幕可以在柜子上卷起。 由于安装了遮光板,来自多个液晶模块中的每一个的图像不会彼此干涉。
