优选地， 所述玻璃面板的底面与第二下固定槽的底臂的内底面之间设有间隙； 所述玻璃 面板的侧面与第二下固定槽的侧臂的内侧面之间设有间隙。通过玻璃面板和第二下固定槽之 间的间隙来实现玻璃面板的自动微调。 所述间隙的宽度为 0.1~10.0mm之间。
优选地， 所述玻璃面板采用单侧固定， 在上固定端中， 所述导光板和玻璃面板的排列玻 璃面板之间通过胶粘层相互贴合。所述胶粘层的长度为等于或者小于玻璃面板的宽度。通过 单侧固定， 使得玻璃面板的另一自由端可自由地在间隙范围内伸缩， 避免其发生弯曲变形， 使其可在自身重力作用下迅速恢复。 在本发明中， 所述上固定端中开设有第一收容槽， 第一下固定端中开设有第二收容槽， 第二下固定端开设有第三收容槽。 所述第一收容槽的深度为 2.0mm~20mm， 所述第二收容 槽的深度为 2.0mm~15mm， 所述第三收容槽的深度为 2.0mm~25mm。
与现有技术相比， 本发明的一种防止显示模组玻璃面板变形的固定装置， 将原有的四点 固定方式， 改为现在的两端定位方式， 仅在导光板和玻璃面板的上下两端将其嵌套固定， 解 决了多点固定方式所产生的挤压变形的问题，采用两端嵌套一侧固定的方式，将玻璃面板悬 空于上固定端和第二下固定端之间，并通过与第二下固定端内侧面和底面之间的间隙，使得 当发生变形时，玻璃面板可凭借自身重力适当微调并迅速恢复，避免了因玻璃面板发生变形 而导致玻璃面板中的彩色滤光片玻璃面板的色阻和排列玻璃面板的侧金属走线对位偏移而 引起的像素漏光等异常现象发生， 可解决大尺寸的液晶面板装配固定问题。

在本发明的优选实施例中，所述下固定端 12包括第一下固定端 120和第二下固定端 122， 第一下固定端 120放置于第二下固定端 122之上，所述导光板 1的下端收纳于第一下固定端 120中， 所述玻璃面板 2的下端收纳于第一下固定端 120和第二下固定端 122之间的间隔带 123之中。 其中， 所述上固定端 10和下固定端 12相对， 导光板 1和玻璃面板 2相互平行， 通过一侧固定将玻璃面板 2悬空固定。为了避免导光板 1和玻璃面板 2之间发生摩擦而产生 弯曲变形，将导光板 1和玻璃面板 2的下端分别放置入两个不同的固定端中， 导光板 1内嵌 于上固定端 10和第一下固定端 120之间， 玻璃面板 2与导光板 1相贴合， 其内嵌于上固定 端 10与第一下固定端 120和第二下固定端 122之间的间隔带 123之间， 以减小玻璃面板 2 和导光板 1之间的摩擦力。
其中， 所述排列玻璃面板 20和彩色滤光片玻璃面板 22相互贴合， 且其下端收纳于第一 下固定端 120和第二下固定端 122之间的间隔带 123之中， 其上端收纳于上固定端 10中， 并于导光板 1相贴合。
其中， 所述上固定端 10中开设有第一收容槽， 第一下固定端 120中开设有第二收容槽， 第二下固定端 122开设有第三收容槽。第三收容槽与第一收容槽大致相当。所述第二下固定 端 122由至少两侧臂 122a和底臂 122b环绕而成， 所述第二下固定端 122的侧臂 122a的内 侧面与玻璃面板 2的侧面相对， 所述底臂 122b的内底面与玻璃面板 2的底面相对， 所述玻 璃面板 2的底面与第二下固定槽 122的底臂 122b的内底面之间设有间隙 124， 所述玻璃面 板 2的侧面与第二下固定槽 122的侧臂 122a的内侧面之间设有间隙 124。 通过设置在玻璃 面板 2的下端与第二下固定端 122的内侧面和内底面之间设置间隙 124， 使得玻璃面板 2在 发生弯曲时， 可利用其自身重力适当微调， 以迅速地恢复直立状态。 其中， 所述间隙 124 的宽度为 0.1~10.0mm之间。 所述第一收容槽的深度为 2.0mm~20mm， 所述第二收容槽的深 度为 2.0mm~15mm， 所述第三收容槽的深度为 2.0mm~25mm。
为了防止玻璃面板 2发生变形， 对其采用单侧固定， 在上固定端 10中， 所述导光板 1 和玻璃面板 2之间通过胶粘层 3相互贴合。 可以理解， 也可以通过其他无边框的固定方式， 在上固定端， 将玻璃面板 2和导光板 1 绑定在一起， 由此实现单侧固定， 利用玻璃面板 2 的悬空来避免其发生弯曲而导致光路对位不正或像素显示异常等现象， 同时，利用玻璃面板 2和第二下固定端 122内侧之间的间隙， 来实现玻璃面板 2的微调， 使其弯曲后亦可自动迅 速恢复， 大大降低了发生形变的几率。其中， 所述胶粘层 3的长度为等于或者小于玻璃面板 的宽度。
图 3为本发明一种防止显示模组玻璃面板变形的固定装置的排列玻璃面板和彩色滤光片 玻璃面板的对位示意图。 在图 3中， 玻璃面板中的排列玻璃面板 20和彩色滤光片玻璃面板 22的上端收纳于上固定端 10中， 由于其通过单侧悬空固定， 另一端自然垂入下固定端 12 中， 两玻璃面板处于自然垂立状态， 使得两者不会发生形变弯曲， 彩色滤光片玻璃面板 22 的色阻 221和排列玻璃面板 20的侧金属走线 201对位正常， 使得彩色滤光片玻璃面板 22 中的色阻层 221和排列玻璃面板 20中的金属走线层 201相互平行对位， 这样， 由彩色滤光 片玻璃面板 22的像素显示正常。
本发明的一种防止显示模组玻璃面板变形的固定装置， 将原有的四点固定方式， 改为现 在的两端定位方式，仅在导光板和玻璃面板的上下两端将其嵌套固定，解决了多点固定方式 所产生的挤压变形的问题，采用两端嵌套一侧固定的方式，将玻璃面板悬空于上固定端和第 二下固定端之间， 并通过与第二下固定端内侧面和底面之间的间隙， 使得当发生变形时， 玻 璃面板可凭借自身重力适当微调并迅速恢复，避免了因玻璃面板发生变形而导致玻璃面板中 的彩色滤光片玻璃面板的色阻和排列玻璃面板的侧金属走线对位偏移而引起的像素漏光等 异常现象发生， 可解决大尺寸的液晶面板装配固定问题。
