    • A method for illuminating a liquid crystal display device, a back-light assembly for performing the same and a liquid crystal display device using the same can improve the front luminance and production yield. Lights from a lamp is incident to a LCD panel side, which are then primarily diffused for a uniformity of the luminous flux of the incident lights. The luminous flux of the primarily diffused lights is condensed with respect to a first orientation component on a plane in parallel with the LCD panel, and then partially and secondarily diffused for extending a view angle of pixels of the LCD panel. After the luminous flux of the secondarily diffused lights is condensed with respect to a second orientation component perpendicular to the first orientation on the parallel plane, the condensed lights are illuminated onto the LCD panel. A diffusion sheet for secondarily diffusing the luminous flux and a condensing sheet for condensing the second orientation component are formed by a single sheet to reduce the manufacturing process of the liquid crystal display device. Also, a defect produced from respective sheets is minimized to enhance the yield.
    • 一种用于照亮液晶显示装置的方法,用于执行该液晶显示装置的背光组件和使用该方法的液晶显示装置可以提高正面亮度和产量。 来自灯的灯入射到LCD面板侧,然后主要用于漫射入射光的光通量的均匀性。 主要扩散的光的光通量相对于与LCD面板平行的平面上的第一取向分量被冷凝,然后被部分和二次地扩散以延伸LCD面板的像素的视角。 在二次漫射光的光通量相对于垂直于平行平面上的第一取向的第二取向分量会聚后,会聚的光被照亮到LCD面板上。 用于二次扩散光束的扩散片和用于冷凝第二取向成分的聚光片由单片形成,以减少液晶显示装置的制造过程。 此外,由各个片材产生的缺陷被最小化以提高产量。
