附图说明
图1是现有的液晶显示器的局部结构示意图；
图2是本发明液晶显示器较佳实施例的局部结构示意图。
本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
以下将结合附图及实施例，对实现发明目的的技术方案作详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
请参照图2所示，图2为本发明液晶显示器较佳实施例的局部结构示意图。本发明一实施例提出的一种液晶显示器，包括前框10、显示面板70及背光模组，该背光模组包括背板30、铝挤20、反射片50、导光板40、 LED光源60，其中：
铝挤20设置在背板30上，铝挤20横截面为L形，该铝挤20具有底板21和与底板21垂直的第一侧板22，背板30为板状，位于铝挤20的底板21的下方并与底板21固定连接。较佳地，背板30为一金属板，金属板上设有固定铝挤20的固定孔31，通过固定孔31与底板21固定连接。
LED光源60设置在铝挤20的第一侧板22的内侧表面上；导光板40位于铝挤20的底板21的上方，该导光板40的入光侧41与LED光源60的发光面相对；反射片50位于导光板40与铝挤20的底板21之间。其中，LED光源60包括固定在铝挤20的第一侧板22的PCB（印刷电路板）61及安装在该PCB61上的若干LED62，PCB61的第一侧面紧贴第一侧板22的内侧表面，与该第一侧面相对的PCB61的第二侧面上设有LED62。
前框10具有顶板11及第二侧板12，顶板11与第二侧板12相互垂直，顶板11位于铝挤20的上方，前框10的第二侧板12与铝挤20的第一侧板22平行设置，第二侧板12紧靠第一侧板22并与该第一侧板22通过螺钉等连接件固定连接。
显示面板70位于导光板40的上方且位于前框10的顶板11下方。
本实施例中，为了固定显示面板70，在导光板40与显示面板70之间设置有第一绝热支撑件80，该第一绝热支撑件80与前框10的顶板11夹持显示面板70。
具体地，本实施例中第一绝热支撑件80可以为易成型并可隔热的橡胶块或塑胶块等，考虑到背光模组内部空间狭小的特点，第一绝热支撑件80以橡胶块较佳。
本实施例中，第一绝热支撑件80的底部的一部分与导光板40的上表面接触且通过粘接的方式固定，该第一绝热支撑件80的底部的其余部分在导光板40的入光侧41悬空，从导光板40的入光侧41延伸至LED光源60的LED62上方，将LED62遮挡，防止漏光，以提高背光模组的出光效果，进而提高液晶显示器的显示效果。
此外，为了配合显示面板70下方的光学膜片（图中未示出）的安装，上述第一绝热支撑件80可以横截面设置为L形，具体地，第一绝热支撑件80具有与导光板40平行的第三侧板81以及与第三侧板81垂直的第四侧板82，第三侧板81及第四侧板82与导光板40的上表面形成固定光学膜片的卡槽；第三侧板81的顶面支撑显示面板70；第四侧板82的底部与导光板40的上表面粘接。为了使前框10更好的定位，本实施例中铝挤20的第一侧板22的顶部接触前框10的顶板11的底部。
上述结构使得背光模组在LED光源60侧水平方向的厚度及组装间隙得到大大的减少，有利于液晶显示器的窄边框设计，同时可将LED光源60及导光板40沿水平方向向外侧偏移一定距离，增大了LED光源60的混光距离，并通过导光板40与显示面板70之间的第一绝热支撑件80遮挡LED光源60，有效防止漏光，提高了液晶显示器的显示效果。
进一步的，考虑到铝挤20因LED光源60的热传导受热而向外部扩散热量，本实施例在铝挤20的第一侧板22的内侧、位于LED光源60的上方设有第二绝热支撑件90，用于阻隔铝挤20上的热量沿该铝挤20的上部向显示面板70扩散，防止显示面板70受热影响显示效果。
具体地，在第一侧板22的内侧、位于LED光源60的上方内凹形成L形台阶（图中未标出），该台阶的台阶面与PCB61的顶面齐平；第二绝热支撑件90紧贴第一侧板22内侧表面设置且位于上述台阶的台阶面与前框10的顶板11之间，该第二绝热支撑件90可以为易成型并可隔热的橡胶块或塑胶块等，考虑到背光模组内部空间狭小的特点，该第二绝热支撑件90同样以橡胶块较佳。上述结构可有效的隔绝铝挤20上的热量传递到显示面板70上，同时，铝挤22上端与第二绝热支撑件90可对显示面板70起缓冲作用，防止显示面板70在沿导光板40延伸的方向上的移动，避免显示面板70受损。
此外，本实施例中铝挤20的底板21的上表面设有支撑反射片50和导光板40的突起101。突起101可以是与铝挤20的底板21一体成型，也可以是与底板21粘接，当突起101与铝挤20的底板21粘接时，该突起101可以为绝热材料，比如可以为橡胶块或塑胶等易成型材质，并具有隔热效果，此种情况下，该突起101的另一作用是：可在背光模组内形成散热空间，提高背光模组的散热效果。
进一步地，为了提高液晶显示器的组装性能，保护显示面板70免受冲击，本实施例在前框10的顶板11与显示面板70的上表面之间还设置有缓冲材100。
需要说明的是，本实施例中通过第一绝热支撑件80承载显示面板70并防止LED光源60漏光，通过铝挤20的第一侧板22的上部、前框10的顶板11及第一绝热支撑件80对显示面板70进行导光板40延伸方向上的定位，防止显示面板70沿导光板40延伸方向的移动，例如，若背光模组为左右侧入光结构，则通过左右侧的铝挤20对显示面板70进行导光板40延伸方向的一个方向进行定位，导光板40延伸方向的另一方向的定位可以采用传统的胶框定位结构。显示面板70在与导光板40延伸方向垂直的方向的定位则通过第二绝热支撑件90和前框10的顶板11来实现。
进一步需要说明的是，本实施例中背板30与铝挤20的底板21的接触区域可以根据实际需要进行设定，即背板30的横截面宽度可以与铝挤20的底板21的宽度相同，也可以小于铝挤20的底板21的宽度。
背板30与铝挤20的底板21的固定方式，可以从背光模组内部通过大头螺钉等连接件固定，具体可以在背板30上设置固定孔31，通过大头螺钉同时将左右对称的两个铝挤20的底板21同时固定。
本实施例背光模组的组装过程如下：
首先通过大头螺钉将背板30与左右对称的两个铝挤20的底板21固定，然后将安装有LED62的PCB61固定在铝挤20上，依次在铝挤20的底板21的上方放置反射片50、导光板40，在导光板40上放置第一绝热支撑件80支撑显示面板70，最后安装前框10，铝挤20的第一侧板22的顶部接触前框10的顶板11的底部，使前框10定位，同时，前框10的第二侧板12紧靠铝挤20的第一侧板22，并与该第一侧板22通过螺钉等连接件固定连接，由此，通过第一绝热支撑件80与前框10的顶板11及第一侧板22的上部夹持显示面板70。
上述液晶显示器实施例中的前框10、背板30、导光板40、铝挤20、LED光源60及反射片50构成本发明的背光模组，在此不作详述。
本发明背光模组及液晶显示器，相比现有的背光模组，省掉LED光源60侧的胶框以及背板30的侧壁，将显示面板70直接固定在铝挤20上，减少了背光模组LED光源60侧水平方向的厚度及组装间隙，有利于液晶显示器的窄边框设计，并增大了LED光源60的混光距离，并通过导光板40与显示面板70之间的第一绝热支撑件80遮挡LED光源60，有效防止漏光，提高了液晶显示器的显示效果，同时降低了制造成本；此外，通过设置在铝挤20上部的第二绝热支撑件90有效的阻止了铝挤20的热量从铝挤20上部传递至显示面板70，进一步提高了液晶显示器的显示效果，而且第二绝热支撑件90与铝挤22上端可对显示面板70起缓冲作用，防止显示面板70在沿导光板40延伸的方向上的移动，避免显示面板70受损。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
