    • The invention eliminates light leakage in liquid crystal panel caused by burrs, i.e., protrusions, on a light waveguide plate causing misalignment when the light waveguide plate is seated in the main frame of a LCD module. The invention includes a a first frame located on the liquid crystal panel, and a second frame assembled with the first frame interposing the liquid crystal panel and the back light. The second frame has a recessed portion formed at a location corresponding to the protrusions of the light waveguide plate, wherein a distance from the fixed side wall of the light waveguide plate to the protrusions is sufficiently short so that dimensional variations between the protruding portion of the light waveguide plate and the recessed portion of the second frame are insignificant.
    • 本发明消除了当光波导板被安置在LCD模块的主框架中时在光波导板上产生不对准的毛刺(即突起)引起的液晶面板中的漏光。 本发明包括位于液晶面板上的第一框架和与插入液晶面板和背光的第一框架组装的第二框架。 第二框架具有形成在对应于光波导板的突起的位置处的凹部,其中从光波导板的固定侧壁到突起的距离足够短,使得第二框架的突出部分之间的尺寸变化 光波导板和第二框架的凹部不重要。
