【技术领域】
本发明涉及液晶显示技术领域，特别是涉及一种背光模组及液晶显示器。

【具体实施方式】
下面结合附图和实施方式对本发明进行详细说明。
请参阅图1，本发明背光模组100的一实施方式，背光模组100包括导光板110、胶框130以及反射片140。
导光板110，该导光板110在于使灯管发出的点光源或线光源转变为面光源，制成该导光板110的材质可为现有的任何制成导光板的材质，例如光学级的亚克力等。
胶框130，靠近导光板110的侧面112设置，可支撑并保护导光板110。
反射片140，其包括第一部分142、第二部分144和第三部分146。其中，反射片140的第一部分142设置在导光板110底面114和/或胶框130的底面134下，反射片140的第二部分144贴合在胶框130远离导光板110的侧面136上，而反射片140的第三部分146贴合在胶框130的顶面132上。
区别于现有技术的情况，本实施方式中的背光模组100中的反射片140设置包括有第一部分142、第二部分144和第三部分146。其中，反射片140的第一部分142设置在导光板110底面114和/或胶框130的底面134下，反射片140的第二部分144贴合在胶框130远离导光板110的侧面136上，而反射片140的第三部分146贴合在胶框130的顶面132上。由于反射片140包括三个部分，使得反射片140在贴合于胶框130底部134之外，还能够与胶框130远离所述导光板110的侧面136以及胶框130的顶面132贴合，通过这种方式，能够使得在胶框130的宽度很窄的情况下，反射片140也能牢固地贴合在胶框130上，从而避免反射片140松动脱落。
进一步地，该背光模组100还包括至少一个光学膜片120，光学膜片120设置在导光板110的顶面上，该顶面为底面114相对的一面。
反射片140的第二部分144通过粘贴技术而粘贴在胶框130远离导光板110的侧面136上，而反射片140的第三部分146也通过粘贴技术而粘贴在胶框130的顶面132上。
更进一步地，反射片140的第三部分146通过粘贴技术而粘贴在胶框130的顶面132上以及光学膜片120上。更具体地说，该反射片140的第三部分146通过粘贴技术而粘贴在胶框130的顶面132上以及光学膜120的顶面122上。
其中，所述粘贴技术是指采用具有粘性的物质将两种不用物件相互粘结的技术手段。该粘贴技术包括但不局限于涂布胶层或粘贴双面胶等技术手段。
本实施方式中，反射片140的第二部分144通过双面胶150而粘贴在胶框130远离导光板110的侧面136上，而反射片140的第三部分146通过双面胶150而粘贴在胶框130的顶面132以及光学膜片120上。
进一步的，请参阅图2，图2是本发明背光模组200的另一实施方式。反射片140的第一部分142还可通过粘贴技术而粘贴在导光板110的底面114和/或胶框130的底面134上。该粘贴技术包括但不局限于涂布胶层或粘贴双面胶等技术手段，本实施方式中采用的是粘贴双面胶150的技术手段。
区别于现有技术的情况，本实施方式中的背光模组100中的反射片140的第一部分142、第二部分144和第三部分146分别通过粘贴技术而粘贴在胶框130的对应位置上，使得反射片140与胶框130贴合得更牢固，不易出现反射片140松动脱落的现象，进一步地该背光模组100还包括光学膜片120，反射片140的第三部分146通过粘贴技术也一并粘贴在光学膜片120上，以使光学膜片120一并被牢固地固定在胶框130内，而且反射片140与光学膜片120所粘贴的重叠部分可反射回漏出的光线，进而提高光线的利用率。
请一并参阅图3至图5，本发明背光模组300的另一实施方式，背光模组300包括导光板310、胶框330以及反射片340。
本实施方式中的导光板310、胶框330分别采用的是与上述背光模组100一致的导光板110和胶框130，在此不再详细描述。
反射片340，其包括第一部分342、第二部分344和第三部分346。其中，第一部分342和第二部分344的贴合位置与上述背光模组100中的反射片140的第一部分142和第二部分144相同。
不同之处在于，该反射片340的第三部分346正对于胶框330的顶面332的表面上设置有多个开口3462，而胶框330的顶面332设置有多个对应的凸起3322。在进行组合时，胶框330的顶面332的多个凸起3322套设在反射片340的第三部分346上的多个开口3462内，以使该反射片340第三部分346能扣合在胶框330的顶面332上。
本实施方式中的背光模组300的反射片340在贴合于胶框330底部334之外，还能够与胶框330远离导光板310的侧面336以及胶框330的顶面332贴合，因此即便在胶框330的宽度很窄的情况下，反射片340也能牢固地贴合在胶框330上，从而避免反射片340松动脱落，而且反射片340的第三部分346的开口3462与胶框330的顶面332的凸起3322相互形成的扣合结构也进一步使得该反射片340更加牢固地贴合在胶框330上。
进一步地，该背光模组300还包括至少一个光学膜片320，该光学膜片320设置在导光板310的底面314的相对一面上。
进一步地，反射片340的第三部分346正对与胶框330的顶面332的表面可通过粘贴技术而粘贴在胶框330的顶面332上。其中，粘贴技术是指采用具有粘性的物质将两种不用物件相互粘结的技术手段。该粘贴技术包括但不局限于涂布胶层或粘贴双面胶等技术手段。
进一步地，反射片340的第三部分346正对与胶框330的顶面332的表面可通过粘贴技术而粘贴在胶框330的顶面332上以及光学膜片320上，更具体地说，该反射片340的第三部分146正对与胶框330的顶面332的表面可通过粘贴技术而粘贴在胶框330的顶面332上以及光学膜片320的顶面322上。该粘贴技术包括但不局限于涂布胶层或粘贴双面胶等技术手段，本实施方式中所采用的是粘贴双面胶350的技术手段。
可以理解的，在此基础上，反射片340的第三部分346背离胶框330顶面332的另一表面上进一步地可涂布一层胶层以进一步地将胶框330顶面332设置的凸起3322粘贴在反射片340的第三部分346设置的开口3462内，以进一步防止反射片340脱落。当然，反射片340的第三部分346背离胶框330顶面332的另一表面上也可进一步地粘贴双面胶350，一方面可将胶框330顶面332设置的凸起3322粘贴在反射片340的第三部分346设置的开口3462内，另一方面还可将该背光模组通过双面胶350的另一面粘贴固定在其他例如液晶面板等结构上。
进一步地，反射片340的第二部分344通过粘贴技术而粘贴在胶框330远离导光板310的侧面336上，该粘贴技术包括但不局限于涂布胶层或粘贴双面胶等技术手段。
进一步地，反射片340的第一部分342还可通过粘贴技术而粘贴在导光板310的底面314和/或胶框330的底面334上，该粘贴技术包括但不局限于涂布胶层或粘贴双面胶等技术手段。
区别于现有技术的情况，本实施方式中的背光模组300中的反射片340的第一部分342、第二部分344和第三部分346可分别通过粘贴技术而粘贴在胶框130的对应位置上，使得反射片340与胶框330贴合得更牢固，更不易出现反射片340松动脱落的现象，即便在外界强力地撞击下，该反射片340也不容易松动脱落。进一步地该背光模组300还包括光学膜片320，反射片340的第三部分346通过粘贴技术也一并粘贴在光学膜片320上，以使光学膜片320一并被牢固地固定在胶框330内，而且反射片340与光学膜片320所粘贴的重叠部分可反射回漏出的光线，进而提高光线的利用率。
可以理解的，在其他一些实施方式中，该胶框顶面并不局限设置有多个凸块，也可设置为一个即可，而反射片的第三部分上也对应设置一个开口即可。
可以理解的，在其他一些实施方式中，该胶框顶面和反射片第三部分并不局限于设置凸起和开口，也可设置卡勾和扣合孔等其他任何能够实现胶框顶面和反射片第三部分相互扣合卡制的结构。
另外，本发明还提供一种液晶显示器，该液晶显示器包括背光模组，其中该背光模组为如上述任意一种所述的背光模组，在此不再赘述。
以上所述仅为本发明的实施方式，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等效流程变换，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。
