    • A backlighting device for display panels operating on the edge lighting method that comprises a light conducting plate made of a light-transmissive material, a layer of light-diffusing material that partly covers one major surface of the light conducting plate, and a light diffusing/reflecting plate that covers the thus covered area of the light conducting plate. The light conducting plate is provided on its exit face with a film that is coarser grained on the exit face than on the entrance face (the side closer to the light conducting plate) and which, when provided on the exit face of the light conducting plate, will increase the luminance of light issuing from the exit face of the light conducting plate. This backlighting device produces satisfactory luminance and can be used as a high-performance model that achieves a high efficiency of power to luminance conversion at least in the direction of the line normal to the exit face.
    • 一种用于边缘照明方法操作的显示面板的背光装置,包括由透光材料制成的导光板,部分覆盖导光板的一个主表面的光漫射材料层,以及光扩散/ 覆盖导光板这样被覆盖的区域的反射板。 导光板在其出射面上设置在出射面上比在入射面(靠近导光板的一侧)更粗糙的膜,并且当设在导光板的出射面上时 会增加从导光板的出射面发出的光的亮度。 该背光装置产生令人满意的亮度,并且可以用作至少在垂直于出射面的线的方向上实现高亮度转换效率的高性能模型。
