Description

显示模组及显示装置 技术领域
本申请涉及显示领域,特别涉及一种显示模组及显示装置。
背景技术
在目前的显示设备中,集成电路板和基板之间的绑定、印刷电路板和基板之间的绑定都是通过各向异性导电胶膜(Anisotropic Conductive Film,以下简称ACF)来实现的,利用ACF纵向电性导通(z方向)、横向绝缘(xy方向)的特性使集成电路板和印刷电路板分别与基板上的相应电路电连接。
随着显示设备的发展,用户对窄边框的需求逐渐强烈。在现有窄边框的设计中,常常将驱动IC的绑定区设置在显示面板的侧面。由于印刷电路板(PCB)设置在显示面板的侧边,使得印刷电路板与显示面板内数据输出端连接的面积较小,阻抗较大,导致信号传输出现异常。

在现有窄边框的设计中,常常将驱动IC的绑定区设置在显示面板的侧面。由于印刷电路板(PCB)设置在显示面板的侧边,使得印刷电路板与显示面板内数据输出端连接的面积较小,阻抗较大,导致信号传输出现异常。本申请基于此技术问题提出了一种显示模组以解决上述技术问题。
请参阅图1~图5,所述显示模组100包括显示区10和位于所述显示区10外围的非显示区20,所述非显示区20包括靠近所述显示区10的密封区21、及远离所述显示区10一侧的绑定区22。
所述绑定区22内设置有第一基板101及位于所述第一基板101上的至少一第一端子220,所述第一端子220从靠近所述显示区10的一侧向远离所述显示区10的一侧延伸,并与所述显示模组100的第一侧面30接触。
在本实施例中,所述第一侧面30上还形成有印刷电路板40,以及子所述印刷电路板40上形成有驱动芯片(未画出),并通过对应的异方性导电胶将驱动芯片粘接在印刷电路板40上。
靠近所述第一侧面30的所述第一端子220在第一截面AA上的第一剖面的面积大于远离所述第一侧面30的所述第一端子220在第二截面BB上的第二剖面面积。
在本实施例中,所述第一截面AA及所述第二截面BB与所述第一侧面30平行。
在本实施例中,所述第一方向X及所述第二方向Y所在的平面可以与所述第一侧面30垂直。
在本实施例中,所述第一截面AA与所述第一侧面30平行。
本申请通过使靠近第一侧面30的端子的剖面面积大于远离该第一侧面30的端子的剖面面积,增加绑定区22内端子与印刷电路板40的接触面积,降低端子与印刷电路板40的接触阻抗,解决了数据信号传输异常的技术问题。
请参阅图2~图3,所述绑定区22包括靠近所述显示区10的第一区221及远离所述显示区10的第二区222。
在一种实施例中,在所述第一基板101至所述第一端子220的方向上,位于所述第一区221的所述第一端子220的高度小于位于所述第二区222的所述第一端子220的高度。
请参阅图2,位于所述第一区221的所述第一端子220的厚度小于位于所述第二区222的所述第一端子220的厚度。
在本实施例中,所述第一端子220至少包括第一金属层227及第二金属层228。其中,所述第二金属层228及以上的金属层位于所述第二区222。
在本实施例中,所述第一端子220可以与所述第一基板101中的金属层在同一道光罩工艺中形成。例如,当所述第一基板101为阵列基板时,所述第一金属层227可以与栅极层在同一道光罩工艺中形成,所述第二金属层228可以与源漏极层在同一道光罩工艺中形成。当所述第一端子220包括三层及以上的金属层时,可以通过第一基板101中的遮光层或像素电极层等,本申请不作具体限制。
或者,所述第一端子220可以通过单独的金属沉积或溅射等工艺,经多段式掩膜版的图案化处理形成厚度不相同的所述第一区221及所述第二区222。
在本实施例中,位于所述第二区222的所述第一端子220在第三截面CC上的第三剖面的形状可以包括梯形、长方形、正方形或三角形中的至少一种。请参阅图2,本实施例中位于所述第二区222的所述第一端子220的剖面形状为梯形,且靠近所述第一侧面30的面与所述第一侧面30平行。
在本实施例中,所述第三截面CC与所述第一侧面30及所述第一基板101垂直。
本实施例通过不同的工艺在绑定区22中形成厚度不相同的第一端子220,靠近所述第一侧面30的所述第一端子220的厚度大于远离所述第一侧面30的所述第一端子220的厚度,增加了所述第一端子220与所述印刷电路板40的接触面积,降低端子与印刷电路板40的接触阻抗,解决了数据信号传输异常的技术问题。
请参阅图3,所述绑定区22内还设置位于所述第一基板101及所述第一端子220之间的第一凸起223,所述第一凸起223靠近所述第一侧面30设置。
在本实施例中,所述第一凸起223可以位于所述第二区222。
与图2相比,本实施例在靠近所述第一侧面30的区域形成一带有一定坡度的凸起,在绑定区22形成所述第一端子220时,根据对应的沉积或者溅射工艺,在所述第一凸起223上形成对应坡度的所述第一端子220。本实施例的所述第一端子220可以包括第一金属层227或者第一金属层227及第二金属层228,此处没有限制。
请参阅图4,位于所述第一凸起223上且靠近所述第一侧面30设置的所述第一端子220与所述第一侧面30的夹角为a,30°≤a≤70°。
在本实施例中,所述第一凸起223在第三截面CC上的剖面形状可以包括梯形、长方形、正方形或三角形中的至少一种。请参阅图3,本实施例中所述第一凸起223在第三截面CC上的剖面形状可以为梯形,所述第一端子220根据该梯形的斜边形成具有一定坡度的所述第一端子220,与所述第一侧面30接触的所述第一端子220面积大于位于所述第一区221内所述第一端子220的剖面积。
在本实施例中,所述第一凸起223的材料可以为无机或有机材料,本申请不作具体限制。所述第一凸起223可以与所述第一基板101中的无机层或有机层在同一道光罩工艺中形成,例如平坦层或者像素定义层等。
请参阅图5,所述密封区21与所述绑定区22具有重叠部分224。
所述密封区21内设置有密封胶210,所述密封胶210覆盖位于所述重叠部分224内的所述第一端子220。
现有技术中的所述绑定区22与所述密封区21分开设置,而本申请将部分所述绑定区22设置于所述密封区21内,缩小了显示模组100的边框间距,实现了窄边框的设计。
请参阅图2~图3,所述绑定区22可以位于所述密封区21内。
本实施例与图5相同或相似,不同之处在于:
所述密封胶覆盖所述绑定区22内的所述第一端子220。
本实施例通过将所述绑定区22完全设置在所述密封区21内,使得密封胶210覆盖所述绑定区22内的所述第一端子220。本实施例不仅进一步保证了显示模组100窄边框的设计,并且所述密封胶的存在对所述第一端子220进行了良好的密封,阻隔了空气中水氧对所述绑定区22内金属端子的破坏。
请参阅图2~图3,所述显示模组100还包括与所述第一基板101相对且平行设置的第二基板102、及位于所述第一基板101与所述第二基板102之间的液晶层103。
在一种实施例中,所述第二基板102在所述第一基板101上的正投影与所述第一基板101重合。
在一种实施例中,所述第一基板101为阵列基板或彩膜基板中的一者,所述第二基板102为阵列基板或彩膜基板中的另一者。
现有技术中,为了进行绑定区22的设置,阵列基板的面积一般大于彩膜基板的面积,以预留绑定区22的面积。本申请通过将绑定区22设置在密封区21内,使得所述第一基板101与所述第二基板102的可以设置成相同的面积。
另外,在进行显示面板母板切割时,一般先根据第一切割线进行彩膜基板的切割,其次根据第二切割线进行阵列基板的切割。本申请通过使所述第一基板101与所述第二基板102的面积相同,因此在进行切割时只需要经过所述第一切割线对显示面板进行切割即可,简化了工艺,提高了生产效率。
本发明还提出了一种显示装置,所述显示装置包括上述的显示模组。所述显示装置的工作原理可以参照所述显示模组,具体不在赘述。可以理解的,所述电子装置包括但不限定于手机、平板电脑、计算机显示器、游戏机、电视机、显示屏幕、可穿戴设备及其他具有显示功能的生活电器或家用电器等。
本发明提供了一种显示模组及显示装置,所述显示模组包括绑定区;所述绑定区内设置有第一基板及位于所述第一基板上的至少一第一端子,所述第一端子从靠近显示区的一侧向远离所述显示区的一侧延伸,并与所述显示模组的第一侧面接触;靠近所述第一侧面的所述第一端子在第一截面上的第一剖面的面积大于远离所述第一侧面的所述第一端子在第二截面上的第二剖面面积。本申请通过使靠近第一侧面的端子的剖面面积大于远离该第一侧面的端子的第一剖面面积,增加绑定区内端子与印刷电路板的接触面积,降低端子与印刷电路板的接触阻抗,解决了数据信号传输异常的技术问题。
综上所述,虽然本申请已以优选实施例揭露如上,但上述优选实施例并非用以限制本申请,本领域的普通技术人员,在不脱离本申请的精神和范围内,均可作各种更动与润饰,因此本申请的保护范围以权利要求界定的范围为准。
