【具体实施方式】
首先请参见图3，图3是根据本发明第一实施例的液晶显示模组的截面图。如图3所示，本发明的液晶显示模组206包括一液晶显示模组的框架组件，该框架组件包括前框201和背框202，前框201包括位于显示面的第一延伸部（未标示）以及由第一延伸部的外侧边缘向背框202延伸的前框侧壁（未标示），背框202包括与第一延伸部对应的底部（未标示）以及与前框侧壁对应的背框侧壁2023。其中，背框侧壁2023设置于前框侧壁与第一延伸部的内侧。第一延伸部上具有开槽2011，背框202的背框侧壁2023上具有突起部2021，突起部2021插置于开槽2011中。在优选实施例中，开槽2011为多边形槽、圆形槽或椭圆形槽，且开槽2011与突起部2021的尺寸相配合，以使突起部2021恰好填充于开槽2011中。另外，在备选实施例中，开槽2011可设置为略大于突起部2021，突起部2021可弹性抵触开槽2011的至少一侧，或设置为开孔、不贯通的凹陷半槽、半孔。
背框202包括背框侧壁2023和弯折部2024，背框侧壁2023的上端朝前框201的显示面延伸且连接弯折部2024的一端，弯折部2024的另一端连接突起部2021。突起部2021与背框侧壁2023分别垂直于弯折部2024，并且其端部向前框201的显示面突出，以嵌入第一延伸部的开槽2011。
框架组件还包括导光板204，导光板204设置于背框202的底面2025上，背框202的底面2025与背框侧壁2023的下端相连，背框侧壁2023上设置有凹槽2022，凹槽2022用于定位LED灯条203，以使得LED灯条203的中心与导光板204的中心在同一平面内，该凹槽2022设置为与LED灯条203的尺寸相配合，以容置LED灯条203。
LED灯条203可通过焊接、卡扣设置、贴附或螺丝209锁附固定设置于凹槽2022中。
请继续参见图3，本发明的液晶显示模组进一步包括光学膜片207、液晶显示面板206、中框205以及垫片208，其中，光学膜片207设置在导光板204上。液晶显示面板206设置在中框205上，垫片208设置在前框201与液晶显示面板206之间。
以下请参见图4，图4是根据本发明第一实施例的液晶显示模组在侧向锁入螺丝209时的截面图。如图4所示，当在侧向以较大力量锁入螺丝209至前框201和背框202以及灯条203时，背框202的突起部2021在受到侧向力的作用后会沿图4中箭头所示方向穿过开槽2011运动，从而抵消侧向力，进而避免了前框201受到垫片208的抵压而变形，因此避免了前框201变形而影响美观及产生漏光的情况发生。
值得注意的是，图4中所示为在液晶显示模组的入光侧（即设置有灯条203的一侧）在前框上设置开槽，在背框设置突起部，在本发明的备选实施例中，也可以在液晶显示模组的非入光侧（即没有设置有灯条203的其他侧）在前框上设置开槽，在背框设置突起部，同样可以达到避免了前框201变形的技术效果。
以下请参见图5，图5是根据本发明第一实施例的标示有导光板厚度参数的液晶显示模组的截面图。如图5所示，在本发明中，于背框202开一凹槽2022，使灯条203可准确定位在凹槽2022内，因此，在实际组装时，只需控制凹槽2022的中心到导光板204的底面2025的距离D’与导光板204的中轴到导光板204的底面2025的距离D一致，即可使得在将灯条203设置在凹槽2022内后，灯条203的中心与导光板204的中轴在同一平面上，从而保证了灯条203的发光效率。而在实际应用中，控制导光板204的中轴到导光板204的底面2025的距离D的大小并不存在任何技术困难，因此，本发明通过在背框202的背框侧壁2023上设置有凹槽2022，用于定位LED灯条203，可使得LED灯条203的中心与导光板204的中心在同一平面内。
通过以上技术方案，本发明通过在前框201设置开槽2011，在背框202设置突起部2021，并将突起部2021设置在开槽2011中，当在侧向以较大力量锁入螺丝209进行固定时，前框201和背框202受到侧向力的作用，使得突起部2021在开槽2011中运动，从而抵消侧向力，进而避免了前框201变形而影响美观及产生漏光的情况发生。
另外，本发明通过在背框202的背框侧壁2023上设置有凹槽2022，用于定位LED灯条203，可使得LED灯条203的中心与导光板204的中心在同一平面内，从而保证了灯条203的发光效率。
以上所述仅为本发明的实施例，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。
