Description

胶框、 背光模组、 显示装置 技术领域
本公开涉及一种胶框、 背光模组和显示装置。 背景技术
液晶显示装置具有轻、 薄、耗电小等优点， 广泛应用于现代化信息设备 中。 由于液晶显示器 （Liquid Crystal Display Device, 简称 LCD)本身不具发 光特性， 需依赖背光源供应充足与分布均匀的光源来达到显示的功能， 因此 背光模组性能的好坏直接影响到 LCD的品质。 在液晶显示装置朝向窄边框 发展的趋势下， 背光模组在提供光源的同时， 既要满足窄边框的外观要求， 又要有效的对 LCD起到保护作用。 LCD的四个角部最易在外力作用下发生 破损， 所以对 LCD角部的保护则尤为重要。
图 1为发明人知道的背光模组结构示意图。如图 1所示，在该背光模组 的设计中， 胶框 1为硬胶材质。 如图 2所示， 胶框 1为一体成型。
为了保护显示面板 2的四个角部，在背光模组的胶框 1的对应角部设计 成逃角部 5， 如图 3所示。 图 3为图 1所示的 A区域的放大图。 这种逃角部 5可避免液晶显示装置受到外力时显示面板 2的角部与硬胶材质制作的胶框 1产生应力而发生破损。
随着显示装置窄边框的发展，对应的背光模组也要求边框越来越窄。 当 胶框 1的壁厚太薄时则无法在角部做出逃角部 5设计， 因为逃角部 5由于胶 框 1的壁厚太薄而会无法注塑成型。 在这种情况下， 只能适当的增加胶框 1 壁厚来保证逃角部 5的成型设计， 这样与窄边框设计矛盾。 也继而取消逃角 部 5， 但这样会使显示面板 2角部破损的风险增大。 发明内容

下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行 清楚、 完整地描述， 显然， 所描述的实施例仅仅是本公开一部分实施例， 而 不是全部的实施例。基于本公开中的实施例， 本领域普通技术人员在没有作 出创造性劳动前提下所获得的所有其他实施例， 都属于本公开保护的范围。

为使本领域技术人员更好地理解本发明的技术方案，下面结合附图和具 体实施方式对本发明作进一步详细描述。 实施例 1
如图 4-8所示， 本实施例提供一种胶框和包括该胶框的背光组件。 胶框 101包括用于固定显示面板的框架 104和位于框架 104的相邻两边连接处的 可发生弹性形变的挡墙 103。
应当理解的是， 根据背光源在 LCD中分布位置的不同， 可以将背光源 分为侧光式背光源和直下式背光源两种， 其中， 侧光式背光源置于 LCD显 示面板的侧方， 直下式背光源置于 LCD显示面板的下方。 本实施例 1以侧 光式背光源的背光模组为例进行介绍。背光模组通常还包括各层膜材、胶带、 导光板和光源等背光源组件等组件， 在此不做赞述。
胶框 101的框架 104可为硬胶材质制作， 对各种背光源组件起到支撑、 定位、 保护作用； 同时， 可嵌合显示面板， 避免不当碰撞、 挤压等对显示面 板中各功能层的损害。
当胶框 101内嵌入显示面板 102后，显示面板 102的角部与可发生弹性 形变的挡墙 103相对应。 挡墙 103可釆用软胶材料制作， 可重点保护显示面 板 102的边角部分， 避免其在受到外力时与硬胶部分作用发生损伤。
例如， 挡墙 103釆用热塑性弹性体材料制作。 应当理解的是， 其它弹性 材料也是可以的，只要能与制作框架 104的硬质材料通过双色模塑工艺一体 形成即可。
例如，所述的热塑性弹性体为丁二烯或异戊二烯与苯乙烯嵌段型的共聚 物、热塑性反式天然橡胶、热塑性聚氨酯橡胶中的任意一种。应当理解的是， 其它热塑性弹性体材料也是可以的，只要能与制作框架 104的硬质材料通过 双色模塑工艺一体形成即可。
例如， 所述的硬质材料为聚碳酸酯、 聚乙烯、 聚丙烯中的任意一种。 应 当理解的是， 其它硬质材料也是可以的， 只要能与制作挡墙 103的热塑性弹 性体材料通过双色模塑工艺一体形成即可，所谓双色模塑工艺是一种注塑工 艺， 其原理为第一种物料经过主射台注射入模腔内， 在冷却时， 模腔空间扩 大， 由副射台注射第二种物料， 以完成整个注塑成型过程。 而扩大模腔空间 的方法包括利用滑板、 闸门等活动内件而造出的 "缩芯"技术； 或是利用旋 转盘、 或旋转模芯等把产品转往第二模腔而成型。 本实施例中的胶框的框架 和挡墙为两种不同的物料， 可通过双色模注塑工艺一体形成。 双色模工艺具 有注塑周期短、 效率高， 重复性高、 品质稳定， 废品率低等特点， 这些特点 可满足本实施例中胶框的生产需求。
如图 4所示，胶框 101包括例如为矩形框架的框架 104和位于矩形框架
104四个角处的挡墙 103。 通常显示面板为矩形， 矩形框架 104的形状与显 示面板相对应， 同时， 挡墙 103位于矩形框架 104的四个角处更有利于保护 矩形面板的角部。
例如， 所述挡墙 103 包括相互垂直的两个边， 其分别与所述框架 104 相邻两边连接， 所述挡墙 103的两个边的连接处为圓弧形。
例如， 所述的挡墙 103与所述框架 104通过双色模注塑工艺一体形成。 图 5为胶框 101的侧视图.如图 5所示， 胶框 101具有用于嵌合显示面 板的凹部 106， 挡墙 103沿与所述胶框 101所在平面垂直的方向的厚度（图 中的 h )与所述凹部 106的深度相等。 这样使显示面板 102的角部的整个厚 度方向上得到挡墙 103的保护。
图 6为图 4中 B部的放大示意图。 如图 6所示， 挡墙 103包括具有在 框架 104的一条边方向的第一长度 a的第一边，和具有在另一条边方向的第 二长度 b的第二边。所述的第一长度 a和第二长度 b与所述的显示面板的尺 寸相对应。即可以根据待嵌入的显示面板的具体型号和应用环境进行延长或 缩短。
如图 6所示，挡墙 103的壁厚 t与所述的框架 104的其他部分的壁厚相 等。 这样方便注塑和模具设计。
本发明的显示模组的四周受到外力作用时， 胶框 101 四周的框架 104 可对显示面板的四边进行保护，而位于胶框 101的四角部分的可发生弹性形 变挡墙 103则可以吸收外界应力， 重点保护显示面板的四个角部， 避免其在 受到外力时发生损伤。 实施例 2
本实施例提供一种显示装置， 包括显示面板和上述的背光模组。所述显 示面板组装于所述背光模组的胶框中。
图 7为该显示装置的结构示意图。如图 7所示，显示面板 102在四个角 处被挡墙 103所保护。 图 8为图 7中 C部的放大示意图，挡墙 103与显示面 板 102之间隔开一段距离 d， 这样在挡墙 103与所述的显示面板 102之间设 定一个适当緩冲距离， 更有利于挡墙 103发挥保护功能。
例如， 所述胶框 101 的挡墙 103 与所述的显示面板之间的距离 d 为 0.1-0.15 mm。
本发明的显示装置的四周受到外力作用时， 胶框 101 四周的框架 104 可对显示装置的显示面板的四边进行保护，而位于胶框 101的四角部分的可 发生弹性形变挡墙 103则可以吸收外界应力，重点保护显示面板 102的四个 角部， 避免其在受到外力时发生损伤。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而釆用的示 例性实施方式， 然而本发明并不局限于此。 对于本领域内的普通技术人员而 言， 在不脱离本发明的精神和实质的情况下， 可以做出各种变型和改进， 这 些变型和改进也视为本发明的保护范围。 本申请要求于 2014年 1月 24日递交的中国专利申请第 201410036000.7 号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一 部分。
