 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。
请参照图3所示的本发明的液晶显示器的背光模组的优选实施例的结构示意图，所述背光模组300包括导光板310、背板320、胶框330、光学膜片340以及光源350。胶框330呈框架结构，其具有四个结构相似的框壁，在图3中仅显示出其中一个框壁。在本实施例中，将以其中一个框壁的结构为例来介绍胶框330的具体结构。
如图3所示，于该胶框330内形成有由这四个框架围绕而成的一收容腔333及一位于收容腔333上方并与收容腔333相连通的容纳腔331。导光板310安装于胶框330的收容腔333内，并位于背板320上方。光学膜片340安装于胶框330的容纳腔331内，并被直接放置在导光板310的上表面（即出光面），这样光学膜片340就能够得到导光板310的支撑，以确保该背光模组300能够为显示面板（未图示）提供均匀的亮度。
如图3所示，该胶框330的收容腔333至少包括一竖直端面334及一与该竖直端面334连接的斜侧壁332，竖直端面334用来固定位于收容腔333内的导光板310，其进一步的结构功能容后详述。斜侧壁332下方形成一容纳光源150的空间，因此在本实施例中斜侧壁332是用作反光斜面，用来将来自光源150的光线反射至导光板310的入光面。
如图3所示，该胶框330的容纳腔331至少包括一水平支撑面335及一遮蔽面336。水平支撑面335与竖直端面334垂直连接，水平支撑面335用来承载位于容纳腔331内的光学膜片340的边缘。遮蔽面336平行于该水平支撑面335，设置在光学膜片340的边缘的上方，防止其漏光。
如图3所示，容纳腔331的遮蔽面336的端部在水平方向上超过水平支撑面335，亦即容纳腔331的遮蔽面336的端部在水平方向上超过收容腔333的竖直端面334。通过这种布局，光学膜片340就可以被固定于收容腔333内、被导光板310直接支撑、并通过遮蔽面336防止漏光。
下面将进一步描述本发明背光模组300的详细结构及其功效。
根据图3所示的本发明的背光模组300的容纳腔331的设计，光学膜片340的边缘延伸超出导光板310的边缘，使得容纳腔331可较好的固定光学膜片340的同时，容纳腔331与光学膜片340的接触部（即遮蔽面336）又可有效的缩短，尽可能的减小遮蔽面336对导光板310的出光面的出光影响，实现背光模组300超窄边框的设计。同时光学膜片340直接设置在导光板310的表面，得到了导光板310有效的支撑，显示面板（未示出）不会出现亮暗不均的现象。
在图3所示的本发明的液晶显示器的背光模组的优选实施例的结构示意图中。胶框330的斜侧壁332是被用作反光斜面，例如可以在斜侧壁332上形成反光层。本发明的背光模组310采用反射式入光的入光方式，光源350发出的光通过设置在斜侧壁332上的反光层反射后从导光板310的入光面入射，这样方便设计光源350的位置，同时使得导光板332的入光可以达到较佳的效果。反光层可以根据用户的需要采用贴覆或蒸镀等方式制得。
在图3所示的本发明的液晶显示器的背光模组的优选实施例的结构示意图中。胶框330的竖直端面334竖直连接该反射面（斜侧壁332），该竖直端面334的顶部低于导光板310的出光面（即水平支撑面335低于导光板310的出光面）；同时光源350设置在反光斜面（斜侧壁332）的下方，该竖直端面334较光源350的任一侧面略接近于导光板310的入光面，以保护光源350。
现有的背光模组的设计如图1和图2所示，反射斜面极易受到导光板的冲击，按照力学原理进行分解，胶框将往上变形，可能导致胶框上方的显示面板（未示出）破片。但由于本发明的背光模组300设置有突出的竖直端面334，使得导光板310无法直接冲击反射斜面（斜侧壁332），而改为冲击突出的竖直端面334，避免了胶框330的向上变形。同时由于竖直端面334较光源350的任一侧面更接近导光板310的入光面，使得竖直端面334还能保护光源350不会受到导光板310的冲击，使得本发明的背光模组300使用更加稳定。此外竖直端面334的顶端（即水平支撑面335）低于导光板310的出光面有利于光学膜片340的安装，例如当光学膜片340装进容纳腔331内，水平支撑面335不能阻挡光学膜片340进入容纳腔331内。
在图3所示的本发明的液晶显示器的背光模组的优选实施例的结构示意图中。背光模组300还包括散热板360，导光板310通过散热板360固定在背板320上；光源350的驱动电路板通过散热板360与背板320连接或直接与背板320连接。如采用大功率的LED作为光源350，光源350的散热问题将大大影响背光模组300的使用寿命及使用时的稳定性。本发明的背光模组300还设置有散热板360，导光板310通过散热板360固定在背板320上，保证了导光板310良好的散热性。同时用户可以根据使用的光源350的发热情况，决定将光源350的驱动电路板通过散热板360设置在背板320上（发热量较大时）还是直接设置在背板320上（发热量较小时）。
作为本发明的液晶显示器的背光模组的优选实施例，本发明的背光模组300的胶框330可为白色或黑色的塑胶胶框。塑胶胶框使得本背光模组300可以承受一定的内部或外部的冲击，保证背光模组300使用的稳定性。同时塑胶胶框白色或黑色的设计使得塑胶胶框不会对导光板310出射光的颜色产生较大影响。
本发明还涉及一种液晶显示器，包括背光模组以及显示面板，所述背光模组包括导光板、背板、胶框、光学膜片以及光源，其中在所述胶框内形成有一收容腔及一位于所述收容腔上方并与所述收容腔相连通的容纳腔，所述导光板安装于所述收容腔内，并位于背板上方；所述光学膜片安装于所述容纳腔内，并被放置在所述导光板的出光面；其中，所述收容腔至少包括一竖直端面及一与所述竖直端面相连接的斜侧壁，所述竖直端面用来固定所述导光板；所述斜侧壁下方形成一容纳所述光源的空间；所述容纳腔至少包括一水平支撑面及一面对所述水平支撑面的遮蔽面，所述水平支撑面与所述竖直端面垂直连接，所述水平支撑面用来承载所述光学膜片的边缘；所述遮蔽面位于所述光学膜片的边缘的上方。所述遮蔽面的端部超过所述竖直端面；所述斜侧壁为反光斜面，其上贴覆或蒸镀有反光层；所述水平支撑面低于所述导光板的出光面。所述光源设置在所述反光斜面的下方，所述竖直端面较所述光源的任一侧面接近于所述导光板的入光面。本发明的液晶显示器的具体实施方式和有益效果与上述的背光模组的具体实施例相同或相似，请参见上述背光模组的具体实施例。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
