附图说明
图1为本发明液晶显示模组一实施例的组装示意图；
图2为图1中A部的局部放大图；
图3为本发明液晶显示模组的光路原理图。
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
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。
本发明提供一种液晶显示模组，参照图1至图3，在本实施例中，该液晶显示模组包括液晶面板1、背板2、光源3以及连接液晶面板1和背板2的框体4，液晶面板1和背板2相对设置，液晶面板1和/或背板2的横截面为弧形，换言之，液晶面板1的横截面形状可以为弧形，或者背板2的横截面形状可以为弧形，或者液晶面板1和背板2两者的横截面形状均可以为弧形。如图1至图3所示，在本发明实施例的液晶显示模组的一个实施方式中，液晶面板1和背板2的横截面形状均为弧形。可以理解的是，液晶面板1和背板2的横截面形状可以是除直线形以外的形状，例如，液晶面板1和/或背板2的横截面形状可以为波浪形、折线形等形状。液晶面板1、背板2和框体4共同围成用于导光的空气腔体5，如图1和图3所示，空气腔体5的截面形状大致为与液晶面板1或背板2横截面形状相似的弧形，光源3设置在空气腔体5的腔壁上。可选地，如图1所示，光源2设置在空气腔体5的侧端，也就是光源2设置在空气腔体5的周向两端。当然，光源3也可以设置在空气腔体5的腔壁的中部。背板2靠近空气腔体5一侧的侧面设有反射片层6，液晶面板1靠近空气腔体5一侧的侧面设有光学膜片层7，光源3发出的光线经反射片层6的反射以及光学膜片层7反射和透射，换言之，光源3发出的光线可以通过反射片层6的反射，并且光源3发出的光线可以通过光学膜片层7的反射和透射，最终穿过光学膜片层7射出，也就是光源3发出的光线通过光学膜片层7透射出空气腔体5外。
在本实施例中，通过将背板2和液晶面板1的横截面设为弧度相适配的弧形，液晶面板1和背板2相对设置，框体4将背板2和液晶面板1连接固定，且液晶面板1、背板2和框体4共同限定出用于导光的空气腔体5，光源3设于空气腔体5的两侧端，具体地，光源3设于空气腔体5周向的两端。光源3射出的光线散射至反射片层6和光学膜片层7，光线传输至光学膜片层7时，部分光线穿过该光学膜片层7射出液晶面板1，部分光线经该光学膜片层7反射至反射片层6（该反射片层6由能够反射光线的片体结构和网点结构组成）；光线传输至反射片层6时，全部光线经反射片层6反射至光学膜片层7（该光学膜片层7部分由能够反射光线的片体结构材料和网点结构材料构成，部分由能够透光的透光材料构成），这样不断地循环利用光能量，从而使光线全部反射至液晶面板1显示出来，从而实现了LCD曲面显示的功能，由于LCD工艺成熟、使用寿命长、生产良品率高、价格较低，从而解决OLED曲面显示工艺不成熟、寿命短、生产良品率低、价格昂贵的技术问题；同时，本发明取消了一般侧入式曲面LCD产品（例如LCD电视）液晶显示模组所需的导光板，减轻了LCD产品的重量，降低了LCD产品的生产成本，提高了LCD产品的市场竞争力。
进一步地，从靠近光源3的近光端至远离光源3的远光端反射片层6的反射率逐渐增大，从近光端至远光端光学膜片层7的反射率逐渐减小、透光率逐渐增大。在本实施例中，靠近光源3的近光端光线强度大，远离光源3的远光端光线强度小，近光端反射片层6反射率小且近光端光学膜片层7反射率大穿透率低，则从光源3射向近光端反射片层6的光线重新反射并散射至光学膜片层7，从光源3射向近光端光学膜片层7的光线小部分高强度的光线（例如两束高强光）穿出液晶面板1至外界，大部分高强度的光线反射并散射至反射片层6再次循环反射，这样光源发出的光线经多次反射循环后至光学膜片层7中部，由于光学膜片层7中部穿透率高反射率低，所以传至光学膜片层7中部的光线大部分（例如五束低强光）穿出液晶面板1至外界，从光学膜片层7中射出的光线分布均匀，从而用户感受到曲面液晶面板1近光端和远光端发出亮度相差不大（即两束高强光与五束低强光的光强度相差不大），也就是液晶面板1的亮度均匀，从而提高了用户视觉效果。
进一步地，反射片层6上至少设有一处沿着背板2弧形径向方向向内凹入的凸起部8。这样，减少光源3发出的光线直接从空气腔体5一端射向该空气腔体5的另一端，即可以使更多的光源3发出光射向反射片层6，避免光源3光能量的浪费。
优选地，凸起部8设于反射片层6的中部，防止凸起部8对光源3发出光进行过多遮挡或导致凸起部8所在侧过线过于集中（即液晶面板1靠近凸起部8侧亮度过大），凸起部8设于反射片层6的中部则使液晶面板1的发光更加均匀。
进一步地，如图2所示，光源3包括LED灯31和灯条32，LED灯31装设于灯条32内部。这样，LED灯31发出的光线能够均匀射在灯条32上，从而经灯条32发出的光线更为均匀，进而提高了经光学膜片层7的光线分布更加均匀，使液晶面板1的发光更为均匀。
优选地，灯条32面向LED灯31出光方向的出光面设有多个用以散射光线的凸块33，LED灯31发出的光线经灯条32出光面上的凸块33散射，以更大的光出射角射向空气腔体5，即光源3发出的光线以更大的分布范围散射在空气腔体5中的反射片层6和光学膜片层7上，避免了光源3发出光线范围过小而导致液晶面板1的发光不均匀，使光线在空气腔体5内的分布更加均匀，进而使液晶面板1的发光更加均匀。具体地，从光学膜片层7射出的光线的分布状况大致为图3所示。
进一步地，液晶显示模组还包括散热部9，散热部9设于空气腔体5周向的两侧端，灯条32均设于该散热部9上，该散热部9由导热性良好的组件组成，例如铝件，散热部9优选地连通光源3与外界空气，便于将光源3发光所产生的热量通过热传递的方式由空气腔体5传至外界空气，从而起到良好的散热作用。
优选地，散热部9调节灯条32转动，灯条32与散热部9的夹角在0至90度范围内变化，散热部9可根据液晶显示模组的显示要求转动以调节灯条32与散热部9的夹角A，具体地，如图2所示，该夹角A可在0至90度范围内变化，从而调整光源3的出光方向，从而调整液晶面板1上的显示效果。
优选地，光学膜片层7靠近空气腔体5的一侧覆盖设有匀光板层10，从而使光源3发出的光线更加均匀地散布在光学膜片层7上，使液晶面板1上的显示更加均匀。
优选地，光学膜片层7和反射片层6上设有具有反射光线功能的网点，光学膜片层7和反射片层6单位区域内网点越多其反射率越大。在光学膜片层7和反射片层6设置网点，并以单位区域内网点的密集程度来调节光学膜片层7和反射片层6反射率是调整反射率的一种较优实施例，此外还能通过不同的光学材料组成及通过软件控制的方法来实现光学膜片层7和反射片层6反射率的不同。
以上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。
