Description

背光模组及液晶显示模组、电视机 技术领域
本发明涉及一种液晶显示产品，特别是用于无边框的背光模组及液晶显示模组、电视机。
背景技术
对于无前框的液晶显示产品，业界目前将液晶面板与中框之间通过双面胶或胶水进行黏贴固定，虽然这种做法简单，而且无需改变原有的产品结构，但是组装后若存在瑕疵或者是在后期进行维修、更换配件时，要想将液晶面板与中框分离，需要克服双面胶或胶水的粘贴力，则非常困难，而且容易损坏液晶面板，导致重工性低，提高了生产成本。
发明内容
为克服现有技术的不足，本发明提供一种背光模组及液晶显示模组、电视机，从而便于拆装。
本发明提供了一种背光模组，包括中框、背板以及设置在中框中的光学膜片、导光板和反射膜片，所述中框内设有内腔，中框上承载有液晶面板，在中框与液晶面板相对的一侧表面上均匀分布有与内腔连通的第一吸孔。
进一步地，所述中框的外侧边缘上设有与内腔连通的微型气阀。
进一步地，所述第一吸孔外设有第一密封胶垫。
进一步地，所述中框与背板相对的一侧表面上均匀分布有与内腔连通的第二吸孔，通过对内腔抽真空，使第二吸孔将背板吸附，实现中框与背板的固定。
进一步地，所述中框与背板之间通过第二密封硅胶垫密封。
进一步地，所述第一吸孔和第二吸孔为圆孔。
进一步地，所述所述第一吸孔和第二吸孔为矩形孔。
本发明还提供了一种液晶显示模组，包括液晶面板，还包括所述的背光模组，所述液晶面板通过对内腔抽真空，使第一吸孔吸附液晶面板，实现液晶面板与中框的固定。
本发发明还提供了一种电视机，包括液晶显示模组，所述液晶显示模组包括液晶面板，所述液晶显示模组还包括所述的背光模组，所述液晶面板通过对内腔抽真空，使第一吸孔吸附液晶面板，实现液晶面板与中框的固定。
本发明与现有技术相比，通过真空吸附的方式吸附液晶面板，替代传统的双面胶或胶水粘贴的方式进行固定，使得的产品出现瑕疵或需要维修时能够更方便的对液晶显示模组进行拆装，而且避免了拆装时损坏液晶面板的风险，降低生产成本。

如图5和图6所示，第一吸孔8和第二吸孔11可采用圆孔或矩形孔，第一吸孔8和第二吸孔11均间隔设置。
本发明的一种液晶显示模组，包括液晶面板1，还包括上述实施例1和实施例2的的背光模组，所述液晶面板1通过对内腔7抽真空，使第一吸孔8吸 附液晶面板1，实现液晶面板1与中框2的固定，液晶面板1与中框2之间通过第一密封硅胶垫9密封。
