Description

一种LCM液晶显示模组
技术领域
本发明涉及液晶显示技术领域，特别是一种LCM液晶显示模组。
背景技术
LCM液晶显示器以其图像清晰细腻，不闪烁，不伤眼，无辐射，低功耗，更轻薄等众多优点而取代了传统的CRT阴极射线管显示器，备受广大消费者青睐。目前较多应用于电子表、手机、PDA、掌上游戏机、学习机、GPS导航仪、数码照相机、数码摄影机、电脑显示器以及电视机等。在汽车，医疗，军事等高可靠性要求领域也均有应用。其中较好的结构设计和构装技术可以在日常应用中可以更节能，更好的保护液晶显示器免受外界环境的影响和破坏，为产品的寿命延长起到非常积极地作用，为产品积累更多的信誉和口碑。
目前，传统的液晶显示模组LCM（Liquid Crystal Module）一般包括FOG液晶显示屏1、导光板2、反射片3、LB（发光条）4、、胶框5以及背板6，导光板2、反射片3、LB4和胶框5组成背光模组，整体结构的组装方式如图1所示，但这种结构的产品强度比较弱，LCM受外力容易破屏或IC断列等问题，因液晶显示屏1中的驱动IC和背光LB4是紧靠背光模组的胶框5的正反面组装在一起的，当LCM持续点亮液晶显示屏的驱动IC和背光的LB4都会同时发热，因为背光胶框5是PC材质，导热系数比较差，很难把热量传导出去，长时间工作对产品的稳定性和寿命有非常大的影响。背光LB组装在背光的胶框5上，因胶框5是PC材质，产品持续点亮或在高温环境下工作，胶框5很容易变形，经常出现爆灯漏光等不良现象对LCM液晶显示模组视觉效果有影响；影响产品的可靠性。
发明内容
针对上述问题，本发明提供了一种LCM液晶显示模组，在液晶显示屏以及LB发热时，可及时将热量散出去，并解决破屏的问题，提高产品亮度，提高产品的可靠性。
本发明采用的技术方案为：
一种LCM液晶显示模组，包括FOG液晶显示屏以及设于FOG液晶显示屏背面的背光模组，所述背光模组包括导光板，导光板的背面设有反射片，导光板的入光口设有LB，背光模组的背面设有起支撑保护作用的金属背板，金属背板的边缘位置设有弯折形成的U型灯罩，反射片、导光板和LB卡接在U型灯罩内，FOG液晶显示屏与U型灯罩的外表面之间还设有一层PET垫片。
优选地，FOG液晶显示屏包括Cell、pol、IC以及线路板。
更优选地，所述线路板为FPC或PCBA。
与现有技术相比，本发明的有益效果在于：本发明提供一种LCM液晶显示模组，将金属背板折弯形成U型灯罩，提高的光的利用率，在相同配置的背光模组上，产品的亮度提升了8%，降低了产品的功耗，节约了成本，同时提升了整个产品的机械强度，同步解决了破屏、IC断裂、背光LB和FOG驱动IC的散热问题。
附图说明
图1为传统的液晶显示模组LCM的示意图；
图2为本发明提供的一种LCM液晶显示模组的示意图。
具体实施方式
根据附图对本发明提供的优选实施方式做具体说明。
图2，为本发明提供的一种LCM液晶显示模组的优选实施方式。如图2所示，该LCM液晶显示模组包括FOG液晶显示屏10以及设于FOG液晶显示屏10背面的背光模组20，所述背光模组20包括导光板21，导光板21的背面设有反射片22，导光板21的入光口设有LB（发光条）23，背光模组20的背面设有起支撑保护作用的金属背板30，金属背板30的边缘位置设有弯折形成的U型灯罩31，反射片22、导光板21和LB23卡接在U型灯罩31内，这样LB23的三面都被金属背板30包围着，可以很好的将LB23的热量传导出去，当产品在高温下工作时，LB23与导光板21不会因为温度过高而出现变形，造成爆灯漏光等不良现象；U型灯罩31结构有很好的反光效果，LB23处于U型灯罩31形成的容腔内，经过U型灯罩31的内侧面反射，整体的亮度提高8%左右，降低了产品的功耗，节约了成本；同时金属背板30形成的U型灯罩31，具有很好的机械强度，提升了整个产品的机械强度。LB23是通过LB胶粘接在导光板21上。LB胶即为双面胶。
FOG液晶显示屏包括Cell（液晶面板）、pol（偏光片）、IC（芯片）以及线路板。该线路板为FPC（柔性线路板）或PCBA（印刷电路板）。
FOG液晶显示屏10与U型灯罩31的外表面之间还设有一层PET垫片40，PET垫片40可填充FOG液晶显示屏10与U型灯罩31外表面的间隙，这样一软一硬的搭配可以很好解决LCM模组在跌落或受外力时，对FOG液晶显示屏内的玻璃和IC的冲击，可以很好的解决破屏和IC断裂的问题。
综上所述，本发明的技术方案可以充分有效的实现上述发明目的，且本发明的结构及功能原理都已经在实施例中得到充分的验证，能达到预期的功效及目的，在不背离本发明的原理和实质的前提下，可以对发明的实施例做出多种变更或修改。因此，本发明包括一切在专利申请范围中所提到范围内的所有替换内容，任何在本发明申请专利范围内所作的等效变化，皆属本案申请的专利范围之内。
