Description

背光模组、背光模组的中框和显示装置
本申请要求在2017年03月27日提交中国专利局、申请号为201720306164.6、公开名称为“背光模组、背光模组的中框和显示装置”的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本公开涉及显示器技术领域，尤其涉及一种背光模组、背光模组的中框和显示装置。
背景技术
液晶显示器具有体积小、功耗低、辐射低等优点，已广泛应用于电脑显示器、笔记本电脑、手机和液晶电视等设备。由于液晶显示器的显示面板本身不发光，因此，为达到显示效果，需要背光模组为其提供光源，目前，背光模组的主要构成组件包括发光元件、反射层、导光板、光学膜层、中框以及背板等，中框用以连接或者定位背光模组中的其他组件。
现有技术中，中框和背板之间一般通过卡勾和卡口卡合连接或通过双面胶连接。对于上述中框和背板的连接方式均存在着弊端，例如，采用中框与背板卡合连接时，中框上设有的卡勾容易刮屑造成背光模组异物不良，对背光模组进行环境信赖性测试中，高温或低温条件下，中框容易变形，导致中框和背板卡合处脱落，维修重工过程中，中框的卡勾容易断裂变形；而采用双面胶固定时，组装过程中容易造成中框与背板分离或错位，维修重工过程中，双面胶起胶易导致胶框或背板报废；因此，现有技术中的背光模组组装的稳定性较差，且后期维修较麻烦。
