摘要	An apparatus and method for displaying large format images, graphics, and videos. The apparatus comprise a layer of column oriented optical fibers, each fiber is illuminated at one end by at least one laser diode, and a second layer which sits in front of the first layer and is parallel to the first layer, whose projected area substantially overlap that of the first layer. The second layer comprises a plurality of optical fibers arranged in rows. In between the first and second layer sits a third layer of optical switching elements. Alternatively, the second layer can be a light diffusing layer. Laser lights emitted from the laser diodes travel in parallel along respective column fiber until they are redirected by optical switching elements which couple the laser lights within the column fibers to the row fibers or to the difflusing layer directly whereby they are scattered by the diffusing elements to reach the viewing audience. The small size of the fibers results in very small fill factor, allowing light absorbing matrix and backing layer to absorb ambient light effectively. The contrast ratio under ambient light condition is further enhanced by the use of multilayer dielectric optical filter to preferentially absorb ambient light.
其他摘要	一种用于显示大格式图像，图形和视频的装置和方法。该装置包括一层列取向的光纤，每一根光纤的一端由至少一个激光二极管照射，第二层位于第一层的前面并与第一层平行，其投影面积基本上重叠第一层的那个。第二层包括成排布置的多个光纤。在第一层和第二层之间设置第三层光开关元件。或者，第二层可以是光漫射层。从激光二极管发射的激光沿着相应的列光纤平行行进，直到它们被光学开关元件重定向，光学开关元件将列光纤内的激光耦合到行光纤或直接耦合到漫射层，由此它们被漫射元件散射到光学开关元件。吸引观众。纤维的小尺寸导致非常小的填充因子，允许光吸收基质和背衬层有效地吸收环境光。通过使用多层介质光学滤波器优先吸收环境光，进一步增强了在环境光条件下的对比度。
