如图1所述，为本发明实施例1的显示模组结构示意图。本实施例提供的显示模组包括液晶面板10、光学膜片20、导光板30和LED模块40，LED模块40包括竖直板41和水平板42，水平板42下表面的一部分紧贴导光板30上表 面，液晶面板10固定于水平板42上表面和光学膜片20上表面。
本实施例中，显示模组还包括弯折的背板60，导光板30和竖直板41的下表面紧贴于背板60的水平部分，背板60的竖直部分与LED模块40的竖直板41高度相同，液晶面板10的一部分设于背板60的竖直部分上表面。
粘贴层70的一面粘贴于液晶面板10下表面，粘贴层70的另一面粘贴于背板60的竖直部分和水平板42上表面，并粘贴于光学膜片20的部分上表面。
显示模组内还可以设置有胶框50，胶框50的下端设于背板60的水平部分，并且侧面紧贴背板60的竖直部分。具体地，胶框50被夹设于LED模块40的水平板42侧面和背板60的竖直部分之间。可以理解的是，本实施例中的胶框50可以省略，LED模块40与背板60的竖直部分直接接触即可。
为了提高显示模组的背光亮度，背板60的水平部分被加工成具有镜面反射效果的反射面。具体地，本实施方式中的背板60制造方法如下：现将原材料的其中一面进行抛光提高粗糙度，然后对抛光后的粗糙表面进行镜面处理形成上反射面60a，最后再通过冲压成型形成弯折的背板结构。其中，本实施例中的镜面处理为银镜反应等化学工艺或者电镀处理。
本实施例通过在背板60的表面集成一体成型的上反射面60a，相比单独设置镜面反射片的传统方式结构更紧凑，显示模组能做得更薄，且反射面不会发生翘曲或变形影响显示效果；同时，相比单独制造反射片，工艺更简单，成本也更低。
实施例2
与实施例1不同的是，本实施例的胶框50的尺寸和设置方式。如图2所示，本实施例中，胶框50与竖直板41高度相同，其下端设于背板60的水平部分，顶端抵接于水平板42下表面。这里，胶框50还起到辅助支撑作用。
实施例3
与实施例1不同的是，本实施例的胶框50的尺寸和设置方式。如图3所示，本实施例中，胶框50与背板60的竖直部分高度相同，其下端设于背板60的水平部分，顶端通过粘贴层70粘贴于液晶面板10下表面。这里，胶框50起到辅助支撑作用。相应地，粘贴层70的一面粘贴于液晶面板10下表面；粘贴层70的另一面粘贴于背板60的竖直部分和水平板42上表面，并粘贴于光学膜片20的部分上表面，同时还粘贴在胶框50的上端端面。
实施例4
与实施例1不同的是，本实施例的显示模组中没有背板，且导光板30底面的光反射结构不同。
如图4所示，本实施例的导光板30包括主体部30a和延伸部30b，延伸部30b与主体部30a底面相同且高度小于主体部30a，竖直板41的下表面紧贴延伸部30b。
胶框50的下端固定于延伸部30b，胶框50的顶端抵接于水平板42下表面，胶框50起到辅助支撑作用。
相应地，粘贴层70的一面粘贴于液晶面板10下表面；粘贴层70的另一面粘贴于水平板42上表面，并粘贴于光学膜片20的部分上表面。
为了提高显示模组的背光亮度，导光板30的底面镀银形成下反射面30c。通过在导光板30的底面集成一体成型的下反射面30c，省去了背板结构，降低了生产成本。相比单独设置镜面反射片的传统方式结构更紧凑，显示模组能做得更薄，且反射面不会发生翘曲或变形影响显示效果；同时，相比单独制造反射片，工艺更简单，成本也更低。
实施例5
与实施例4不同的是，本实施例的胶框50的尺寸和设置方式。如图5所示，胶框50的下端固定于延伸部30b，胶框50的顶端抵接于液晶面板10下表面，胶框50起到辅助支撑作用。相应地，粘贴层70的一面粘贴于液晶面板10下表面；粘贴层70的另一面粘贴于水平板42上表面，并粘贴于光学膜片20的部分上表面，同时还粘贴在胶框50的上端端面。
以上所述是本申请的几种具体实施方式，仅用以解释本发明，使本领域的技术人员对技术方案理解更透彻，应当指出的是，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
