Description

背光模组
技术领域
[0001] 本实用新型属于液晶显示技术领域，具体涉及一种背光模组。
背景技术
[0002] 背光模组是液晶显示模组的重要组成部分，起到了发光显示的作用，但用户从液晶显示屏的侧面观看画面时，背光模组会出现漏光现象。出现此问题的主要原因在于:技术人员将导光板固定安装于胶框内时，将卡扣设计到了导光板上，卡扣作为导光板的一部分，光线的折射将汇聚于卡扣形成亮光，然后遮光膜往往对侧边的遮光效果不是很好。
发明内容
[0003] 本实用新型针对现有技术的不足，提供了一种背光模组，解决了传统液晶显示模组容易出现漏光的问题，提高了整个背光源的显示效果与画面品质。
[0004] 本实用新型采用的主要技术方案是:一种背光模组，其特征在于，所述背光模组从下到上依次层叠设计有:铁框、反射膜、胶框、导光板、扩散膜、下增亮膜、上增亮膜和遮光膜，所述胶框上设计有卡扣，所述导光板上开设有与卡扣对应位置的卡槽，所述卡扣安装于卡槽内。
[0005] 本实用新型还采用如下附属技术方案:
[0006] 卡扣安装于卡槽内采用的是间隙配合。
[0007] 胶框的上表面和下表面分别设计有向胶框两表面中间方向延伸的卡扣。
[0008] 卡扣向胶框两表面中间方向延伸的基准面与胶框的上表面或下表面相平齐。
[0009] 导光板的上表面与下表面分别开设有卡槽。
[0010] 导光板固定安装于所述胶框的上表面与下表面之间。
[0011] 采用本实用新型带来的有益效果是:解决了传统液晶显示模组容易出现漏光的问题，提高了整个背光源的显示效果与画面品质。
附图说明
[0012] 以下结合附图作进一步说明:
[0013] 图1为本实用新型背光模组的分解示意图；
[0014] 图2为本实用新型背光模组的胶框结构图；
[0015] 图3为本实用新型背光模组的导光板结构图；
[0016] 其中部件名称对应的标号如下:
[0017] 铁框1、反射膜2、胶框3、导光板4、扩散膜5、下增亮膜6、上增亮膜7、遮光膜8、卡扣9、卡槽10。
具体实施方式
[0018] 如图1-3所示，在本实施例中，一种背光模组，从下到上依次层叠设计有:铁框1、反射膜2、胶框3、导光板4、扩散膜5、下增亮膜6、上增亮膜7和遮光膜8，其中胶框3的上表面和下表面分别设计有向胶框3两表面中间方向延伸的卡扣9,导光板4的上表面与下表面上分别开设有与卡扣9对应位置的卡槽10，卡扣9向胶框3两表面中间方向延伸的基准面与胶框3的上表面或下表面相平齐，导光板4固定安装于胶框3的上表面与下表面之间，卡扣9间隙配合安装于卡槽10内。
[0019] 本实用新型不局限于以上实施例，凡是由本领域技术人员根据本实用新型的技术方案得出的其他实施方式，同样落在本实用新型的保护范围之内。
