Description

一种防止显示模组玻璃面板变形的固定装置
技术领域
本发明涉及一种液晶装置,尤其是指一种可防止显示模组的玻璃面板变形的固定装置。
背景技术
传统的液晶模组通常采用天侧,地侧,左侧,右侧共四个边固定玻璃面板,应用于大尺寸面板时,如32inch以上。参照图2所示,由于玻璃面板通过其上下左右四端固定,玻璃面板容易发生弯曲形变,且没有可伸缩调整的空间,致使阵列玻璃面板20’和彩色滤光片玻璃面板22’之间对位发生偏移,彩色滤光片玻璃面板22’的色阻221’和阵列玻璃面板20’的侧金属走线201’对位偏移,从而导致像素露光,宏观表现为串扰严重,对比度降低。
因此,有必要提供一种适用于大尺寸面板上的防止显示模组的玻璃面板变形的固定装置。
发明内容
为了实现上述目的,本发明提供一种防止显示模组玻璃面板变形的固定装置,用于收纳并固定导光板和玻璃面板,所述玻璃面板包括相互贴合的阵列玻璃面板和彩色滤光片玻璃面板,阵列玻璃面板中设有金属走线层,彩色滤光片玻璃面板中设有色阻层,由上固定端和下固定端组成,所述导光板、阵列玻璃面板和彩色滤光片玻璃面板的上端收纳于上固定端中,下端收纳于下固定端中,使得彩色滤光片玻璃面板中的色阻层和阵列玻璃面板中的金属走线层相互平行对位。
优选地,所述下固定端包括第一下固定端和第二下固定端,第一下固定端放置于第二下固定端之上,所述导光板的下端收纳于第一下固定端中,所述玻璃面板的下端收纳于第一下固定端和第二下固定端之间的间隔带之中。所述第二下固定端由至少两侧臂和底臂环绕而成,所述第二下固定端的侧臂的内侧面与玻璃面板的侧面相对,所述底臂的内底面与玻璃面板的底面相对。
优选地,所述玻璃面板的底面与第二下固定端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端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端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阵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阵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。

具体实施方式
参照图1所示,为了保证液晶显示模组的导光板和玻璃面板相互对齐,且防止玻璃面板发生变形,本发明提供了一种防止显示模组玻璃面板变形的固定装置,其用于收纳并固定导光板1和玻璃面板2,所述固定装置由上固定端10和下固定端12组成,通过上固定端10和下固定端12将导光板1和玻璃面板2的两端,其中,所述导光板1和玻璃面板2的上端收纳于上固定端10中,下端收纳于下固定端12中。
其中,所述玻璃面板2包括相互贴合的阵列玻璃面板(Arraycell)20和彩色滤光片玻璃面板(CFcell)22,阵列玻璃面板20中设有金属走线层201,彩色滤光片玻璃面板22中设有色阻层221,所述阵列玻璃面板20与导光板1相对,阵列玻璃面板20和彩色滤光片玻璃面板相互对齐贴合,由导光板1射出的光线依序由阵列玻璃面板20和彩色滤光片玻璃面板22射出,通过阵列玻璃面板20的金属走线层201和彩色滤光片玻璃面板22之间的色阻层221的对位来呈现像素。
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,所述阵列玻璃面板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端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端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阵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,玻璃面板中的阵列玻璃面板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和阵列玻璃面板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和阵列玻璃面板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阵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。
