一种液晶模组
交叉引用
本申请要求在2015年11月25日提交中国专利局、申请号为201520953069.6、发明名称为“一种液晶模组”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及光学领域，尤其涉及一种液晶模组。
背景技术
LCD(Liquid Crystal Display，液晶显示器)是一种平面超薄的显示设备，它具有耗电低、辐射小、画面柔和不伤眼等优点，因而被广泛应用于电脑、平板、手机等各类电子产品中。
液晶模组是液晶显示器的重要组成部分。液晶模组包括背光源。图1示出了一种包括侧入式背光源的的液晶模组。图1为现有技术中液晶模组的横切面结构示意图。如图1所示，液晶模组包括前框11、中框12、背板13、灯条14、液晶面板15、光学膜片组16、导光板17、反射膜18。反射膜18位于背板13上方，导光板17位于反射膜18上方，光学膜片组16位于导光板17上方，液晶面板15位于光学膜片组16上方。其中，灯条14贴附于背板13的内侧，中框12贴附于前框11的内侧，背板13的一部分贴附于前框11，且中框12的材料为塑胶，该塑胶通常是含有10％的GF(Glass Fiber，玻璃纤维)的PC(Polycarbonate，聚碳酸酯)。图1所示的液晶模组取消了左右两侧的散热片。而通常前框11和背板13的材质都为铝，导热性能好。因此，图1所示的液晶模组，灯条14产生的热能能够通过背板13快速传导到前框11，造成前框11的外观接触表面温度偏高，在用户触摸前框11的外观时会有烫手的感觉。
申请内容
本申请实施例的目的在于提供一种液晶模组，降低液晶模组前框的温度，提升用户满意度。
为实现上述目的，本申请实施例提出了一种液晶模组，包括前框、中框、灯条和背板，所述中框位于所述前框内侧，所述灯条和所述背板位于所述中框内侧，其特征在于，所述灯条贴附于所述中框内侧，所述背板的一部分贴附于所述中框，所述前框与所述中框之间留有第一间隙，所述背板与所述前框之间留有第二间隙。
进一步地，上述液晶模组还可具有以下特点，所述前框与所述中框之间通过窄筋位相连。
进一步地，上述液晶模组还可具有以下特点，所述中框设有与所述灯条平行的内隔板，所述灯条贴附于所述内隔板内侧。
进一步地，上述液晶模组还可具有以下特点，所述背板的一部分贴附于所述内隔板外侧。
进一步地，上述液晶模组还可具有以下特点，所述中框设有与所述内隔板平行的外隔板，所述背板的一部分贴附于所述外隔板内侧。
进一步地，上述液晶模组还可具有以下特点，所述第一间隙的宽度小于或等于0.5毫米。
进一步地，上述液晶模组还可具有以下特点，所述中框的材质为导热材料。
进一步地，上述液晶模组还可具有以下特点，所述导热材料为铝挤型材。
本申请实施例的液晶模组，不仅满足了散热需要，还有效降低了液晶模组的前框的温度，从而提升了用户的满意度。
附图说明
图1为现有技术中液晶模组的横切面结构示意图。
图2为本申请实施例中液晶模组的横切面结构示意图。
具体实施方式
以下结合附图对本申请的原理和特征进行描述，所举实施例只用于解 释本申请，并非用于限定本申请的范围。对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，根据本申请精神所获得的所有实施例，都属于本申请的保护范围。
实施例一
图2为本申请实施例中液晶模组的横切面结构示意图。如图2所示，本实施例中，液晶模组包括前框21、中框22、背板23、灯条24。其中，中框22位于前框21内侧，背板23、灯条24位于中框22内侧，灯条24贴附于中框22内侧，背板23的一部分贴附于中框22，前框21与中框22之间留有第一间隙211，背板23与前框21之间留有第二间隙231。
参见图2，在本申请实施例中，液晶模组还可以包括液晶面板25，液晶面板25位于中框22内侧。
参见图2，在本申请实施例中，液晶模组还包括光学膜片组26、导光板27、反射膜28。光学膜片组26、导光板27、反射膜28也位于中框22内侧。
在本申请实施例中，中框22的材质可以为导热材料。本申请实施例将中框22的材质换为导热材料，有利于将灯条24产生的热能分散到中框22，中框22再将热能传导给背板23。而由于第一间隙211的存在，中框22到前框21的热传导受到阻碍，仅有很小部分的热能可以传导到前框21，这样就大大降低了前框21的温度，同时也满足了灯条24的散热需要。
在本申请实施例中，第一间隙211的宽度可以小于或等于0.5毫米。
本申请实施例的液晶模组，通过设计阻碍热能传导到前框的结构，满足了散热需要，还有效降低了液晶模组的前框的温度，从而提升了用户的满意度。
实施例二
参见图2，在本申请实施例中，前框21与中框22之间可以通过窄筋位222相连。在具体应用中，窄筋位222的厚度(即上下板之间的距离)可以控制在1mm(毫米)以内。参见图2，在本申请实施例中，中框22可以设有与灯条24平行的内隔板221，灯条24贴附于内隔板221的内侧。此时，背板23的一部分可以贴附于内隔板221的外侧。此时，中框22可以设有与内隔板22平行的外隔板(图2中中框22上的与内隔板22平行 的部分可以视为外隔板)，背板24的一部分可以贴附于该外隔板的内侧。需要说明的是，这里所说的内隔板和外隔板都属于中框的组成部分，而不是中框之外的其他部件。
其中，用于制作中框22的导热材料可以为铝挤型材。在本申请其他实施例中，制作中框22的导热材料还可以为能够代替铝挤型材的其他材料。
本申请实施例的液晶模组，通过设计阻碍热能传导到前框的结构，并可以进一步通过将中框的材料更换为导热材料，满足了散热需要，还有效降低了液晶模组的前框的温度，从而提升了用户的满意度。
以上所述仅为本申请的较佳实施例，并不用以限制本申请，凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
