Description

一种液晶显示装置及其制造方法以及光学膜片
【技术领域】
本发明涉及液晶显示领域， 更具体的说， 涉及一种液晶显示装置及其制造 方法以及光学膜片。
【背景技术】
液晶显示装置由于功耗小、 体积小而越来越受到欢迎， 然而随着液晶显示 技术的发展， 一些存在的问题也被发掘出来。
如图 1所示， 为一种现有液晶显示器的液晶显示模组的结构， 液晶显示模 组结构是通过胶框 25连接， 使液晶面板 10和背光模组 20组装到一起实现液晶 显示器的正常工作的。 液晶面板 10处于最上面， 由胶框 25上的支撑部 251支 撑， 胶框 25下面压有光学膜片， 所述光学膜片包括： 第一光学膜片 22、 第二光 学膜片 23以及第三光学膜片 24。 为了降低材料成本， 本申请人曾试图尝试如图 2中所示的方案， 液晶显示模组分别通过四个分件式的胶框 25对液晶面板的四 个角区域进行支撑， 通过这种结构组装的液晶模组有一个问题， 即因为分件式 的胶框 25之间具有间隔， 使得液晶面板在遇到压力时产生向下的弯曲， 继而使 得液晶面板的上得黑色矩阵发生移动， 从而使得漏光现象发生而产生水波纹现 象， 严重影响到了 LCD的画面质量； 另外， 对于分件式交框 25而言， 位于液 晶面板的四个分件式的胶框 25间距过大， 致使液晶面板与光学膜片之间间隙过 大而导致侧边漏光， 使得整个模组的光学品味受到严重影响。
【发明内容】
本发明所要解决的技术问题是提供一种抗压能力强、 显示效果优秀的液晶 显示装置及其制造方法以及光学膜片。
本发明的目的是通过以下技术方案来实现的： 一种液晶显示装置， 包括： 光学膜片以及液晶面板， 所述光学膜片的边缘设置有折边， 所述液晶面板设置 于所述折边上。
优选的， 所述液晶显示装置包括有胶框， 所述胶框上设置有用于限制液晶 面板边缘的凸台。 利用凸台对液晶面板的四个边缘进行抵紧， 从而限制液晶面 板在其板面所在平面的方向的自由度。
优选的， 所述光学膜片包括多层， 所述折边为所述光学膜片的任一层的边 缘翻折至最上层的上表面形成。 利用光学膜片进行翻折， 工艺简单。
优选的， 所述光学膜片包括： 位于底层的第一光学膜片、 位于中层的第二 光学膜片以及位于最上层的第三光学膜片， 所述折边为所述第三光学膜片的边 缘翻折至其上表面形成。 利用膜片本身进行翻折形成折边， 方便于组装时的操 作。
优选的， 所述光学膜片包括： 位于底层的第一光学膜片、 位于中层的第二 光学膜片以及位于最上层的第三光学膜片， 所述折边为所述第一光学膜片的边 缘翻折至第三光学膜片的上表面形成。 这样可以利用最底下的第一光学膜片对 第二、 第三光学膜片进行定位。
优选的， 所述折边为贴在所述光学膜片上的与所述光学膜片为分体结构的 薄片。 这样有利于光学膜片的加工， 不需要进行剪裁， 也不需要对现有光学膜 片进行更改工艺。
一种液晶显示装置的制造方法， 包括：
A: 在光学膜片的边缘处设置折边的步骤；
B： 将液晶面板设置到折边上的步骤。
优选的， 所述步骤 A中， 在光学膜片的边缘处设置折边是通过将与所述光 学膜片一体成型的预折边进行翻折， 所述预折边与膜片主体之间设置有预折线。 使光学膜片的翻折能够按照预定路径翻折， 同时也使翻折处的结构更平整。
优选的， 所述步骤 A中， 在光学膜片的边缘处设置折边是通过将与所述光 学膜片分体的预折边粘贴到所述光学膜片上。 这样有利于光学膜片的加工， 不 需要进行剪裁， 也不需要对现有光学膜片进行更改工艺。 一种光学膜片， 所述光学膜片的边缘设置有折边。
本发明由于在液晶显示装置的光学膜片上设置了折边， 并将液晶面板设置 在所述折边之上， 使得液晶面板的边缘与光学膜片边缘上的折边之间无间隔， 而液晶面板与可视区的光学膜片之间只有细微的间隙， 这样， 即使液晶面板外 侧不设有胶框， 由于液晶面板上的黑矩阵的设计， 也不易发生漏光的现象。 另 外， 由于液晶面板的边缘与用于支撑的折边是设置在液晶面板边缘的连续的折 边， 也就是说， 折边的长度至少大于液晶面板的边缘的长度， 这样， 使得液晶 面板的整个边缘都有连续的支撑面支撑， 而不是分件式胶框仅在四个角支撑的 方式， 提高了液晶面板的抗压强度， 进而有效避免受压时发生过大变形而导致 黑矩阵或其他结构发生移动， 产生漏光出现水波纹现象。 再者， 本发明可以利 用光学膜片本身进行翻折或是利用光学膜片的裁剪料在光学膜片上形成折边， 也就不需要单独设置构件用于制作光学膜片上的折边， 其加工方便， 只需要进 行极小的工艺更改即可， 生产成本较为低廉。

其中： 10、 液晶面板， 20、 背光模組， 21、 导光板， 22、 第一光学膜片， 23、 第二光学膜片， 24、 第三光学膜片， 25、 胶框， 26、 外框， 27、 背板， 241、 折边， 242、 预折边， 243、 预折线， 251、 支撑部， 252、 凸台, 77、 间隙。 【具体实施方式】
下面结合附图和较佳的实施例对本发明作进一步说明。
如图 3 所示为本发明所述的液晶显示装置的液晶显示模組， 其包括背光模 组 20以及液晶面板 10, 其中背光模组 10包括： 背板 27 , 设置在背板 27内的 导光板 21设在导光板 21出光面上的第一光学膜片 22、第二光学膜片 23以及第 三光学膜片 24, 设置在背板 27外围的胶框 25 以及设置在胶框 25外围的外框 26; 在背光模组 20的光学膜片的最上一层的第三光学膜片 25的边缘上表面设 置有折边 241， 液晶面板 10设置在第三光学膜片 24上的折边 241上， 液晶面板 10由所述折边 241进行支撑，折边的宽度优选在液晶面板 10的有效显示区之外， 以避免影响到液晶面板 10的正常显示。 由于液晶面板 10是有折边 241进行支 撑， 使得液晶面板 10的边缘与折边 241之间无间隔， 也就是液晶面板 10与光 学膜片之间的间隔由折边 241 封闭， 这样， 也就避免了液晶显示装置由于使用 分件式胶框支撑液晶面板而发生漏光的现象。 另外， 由于液晶面板 10的边缘与 用于支撑的折边 241 之间无间隔， 也就是说， 折边的长度至少大于液晶面板的 边缘的长度， 这样， 使得液晶面板的整个边缘都有连续的支撑， 而不是分件式 胶框仅在四个角支撑的方式， 提高了液晶面板 10的抗压强度， 进而有效避免受 压时发生过大变形而导致黑矩阵或其他结构发生移动， 也就避免了产生漏光出 现水波纹现象。
胶框 25依然采用分件式的结构， 这样有利于削减背光模组的胶框 25制造 成本； 胶框 25上设置有凸台 252, 凸台 252与液晶面板 10的边缘抵紧, 四个分 件式胶框 25分别设置在液晶面板 10的四个角上， 用于限制液晶面板 10在其板 面所在平面的方向的自由度。 液晶面板 10在垂直于其板面方向的自由度由所述 折边 241以及外框 26进行限制。
在本发明实施例中光学膜片包括： 位于底层第一光学膜片 22、 位于中层第 二光学膜片 23以及位于最上层的第三光学膜片 24, 其中， 折边 241设置在第三 光学膜片 241之上； 光学膜片的数量根据需要而设定。 如图 4及图 5所示为第 三光学膜片 24的制造方法及其结构， 如图 4所示， 首先在第三光学膜片 24的 边缘处设置有与第三光学膜片 24—体的预折边 242, 预折边 242与第三光学膜 片 24的主体之间设置有预折线 243 , 预折线 243可以是设置在第三光学膜片 24 边缘处的不连续的缝隙， 也可以是压痕， 这样便于将预折边 242 进行翻折形成 如图 5所示的折边 241。
当然， 也可以另外设置与第三光学膜片分体的预折边， 即另外设置一薄片， 并通过粘贴或其它方式将预折边（即所述薄片） 贴合到第三光学膜片上形成折 边， 薄片可以使用光学膜片的裁剪料制成， 这样， 可以在现有标准加工的光学 膜片上进行， 而不需要更改光学膜片的过多加工工艺， 节省生产成本。
如图 4所示， 第三光学膜片 24翻折预折边 242至其上表面形成如图 5所示 的折边 241， 但是由于翻折不是折断的翻折， 折边 241与第三光学膜片 24之间 在预折线 243附近会有一定间隙 77使得此处略突出 （如图 6所示）， 为了避免 出现这种情况， 如图 7所示， 可以利用第二光学膜片 23翻折至第三光学膜片 24 的上表面形成折边 241 , 这样在翻折处就不会出现突出的情况。 当然， 也可以如 图 8所示，利用第一光学膜片 22翻折至第三光学膜片 24的上表面形成折边 241 , 使得第一光学膜片 22包裹第二光学膜片 23及第三光学膜片 24, 起到对第二光 学膜片 23及第三光学膜片 24的定位作用。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明， 不 能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通 技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若千简单推演或替 换， 都应当视为属于本发明的保护范围。
