在对本公开实施例提供的拼接显示屏的制造方法及拼接显示屏进行详细说明之前,有必要对于相关技术进行以下说明:
在相关技术中,拼接显示屏包括相互拼接的至少两个子显示屏,通常拼接显示屏中采用玻璃材质作为表面覆盖层,即保护盖板11,来保证整个显示模组的可靠性。子显示屏的制造过程如下:首先,将母板进行第一次切割,而得到多个显示面板12,再将显示面板12与保护盖板11贴合一起得到子显示模组,对该子显示模组进行第二次切割,而得到子显示屏。其中第二次切割一般采用激光进行一体化切割,但是,由于保护盖板11的玻璃厚度较厚(约为0.4~0.7mm),这就导致激光无法进行子显示模组的一体化切割,而保护盖板11在贴合时相对显示面板外扩,而预留贴合公差,如图2所示,这就导致整个子显示屏的边框为保护盖板11的外扩边框尺寸d,相对显示面板12自身设计边框D1有所增大,这样子显示屏拼接后,拼接缝增大,影响显示效果。
为了解决上述问题,本公开实施例中提供了一种拼接显示屏的制造方法及拼接显示屏,能够减少拼接缝,以提升显示效果。

步骤S02、提供保护盖板200;
其中,所述保护盖板200可以选用玻璃材质,其厚度可以为0.4~0.7mm,当然,所述保护盖板200的具体材质及厚度不限于此。
步骤S03、将所述保护盖板200与所述显示面板100贴合一起,组成子显示模组,其中如图4所示,所述保护盖板200包括位于所述显示区AA外围的第二边框区210,所述第一边框区110的边框宽度D1大于或等于所述第二边框区210的边框宽度d;
其中所述保护盖板200可贴合于所述显示面板100的发光侧,如图4所示,在显示面板100的发光侧还可设有偏光片300等,通过光学胶400实现显示面板100与保护盖板200之间的贴合,保护盖板200显示区AA外围的第二边框区210相较于显示面板100的第一边框区110更窄,也就是,保护盖板200进行内缩设计;
步骤S04、如图6所示,对所述子显示模组进行第二次切割,所述第二次切割的切割线a为所述第一边框区110和所述预留切割边框区120之间的边界线,除去所述预留切割边框区120,得到子显示屏;
其中可采用激光切割方式,来对所述子显示模组进行一体化切割,由于 所述保护盖板200内缩设计,因此,激光切割时无需切割保护盖板200,沿显示面板100上的第一边框区110与预留切割边框区120之间的边界线切割,而去除掉所述预留切割边框区120。
步骤S05、将多个所述子显示屏进行拼接,得到所述拼接显示屏。
如图4至图8所示,由于所述保护盖板200内缩设计,整个子显示屏的边框尺寸即为所述显示面板100的第一边框区110的边框尺寸,这样,拼接显示屏的拼接缝宽度D为:D=D1+D2+D△,其中,D1为相邻两个子显示拼中的一个子显示屏中所述第一边框区110的边框宽度;D2为相邻两个子显示拼中的另一个子显示屏中所述第一边框区110的边框宽度;D△为相邻两个子显示屏的拼接组装公差值。
相关技术中拼接显示屏的拼接缝宽度D’为:D’=D1’+D2’+D△,其中,D1’为相邻两个子显示拼中的一个子显示屏中保护盖板的外扩边框宽度;D2’为相邻两个子显示拼中的另一个子显示屏中保护盖板的外扩边框宽度;D△为相邻两个子显示屏的拼接组装公差值,由于D1’大于D1,D2’大于D2。
由以上可知,相较于相关技术中保护盖板外扩设计的方案,通过将子显示屏中的保护盖板200的第二边框区210尺寸设计为比显示面板100的第一边框区110的尺寸窄,也就是说,保护盖板200的外形尺寸内缩,相较于相关技术中保护盖板200外扩设计的方案来说,能够减小拼接缝宽度,实现窄边框需求,提升显示效果。
在本公开实施例中,由于保护盖板200进行内缩设计,各子显示屏中显示面板100的外侧边缘会与保护盖板200的外侧边缘之间有一定空白区域,也就是说,如图5所示,所述显示面板100的第一边框区110在面向所述保护盖板200的一侧面包括超出所述保护盖板200边缘的第一区域,在该第一区域内可通过胶水填充,形成涂胶层500。
示例性的,所述涂胶层500可以通过两种方式来形成:
第一种方式,在上述步骤S03之后,步骤S04之前,所述方法还包括:
步骤S031、如图5和图6所示,在所述第一区域、所述预留切割边框区120以及所述保护盖板200的边缘侧面涂胶,形成涂胶层500,并对所述涂胶 层500固化。
并且,在本示例性的实施例中,上述步骤S04中,在对所述子显示模组进行第二次切割时,对所述显示面板100及固化后的所述涂胶层500进行一体化切割,以去除所述预留切割边框区120以及所述涂胶层500中与所述预留切割边框区120中对应的部分,得到所述子显示屏,其中经所述第二次切割后得到的所述涂胶层500的外侧边缘与所述显示面板100的第一边框区110的外侧边缘侧面齐平。
由此可见,本公开实施例提供的拼接显示屏的制造方法,通过设计内缩的保护盖板200外形尺寸,且在保护盖板200的外侧边缘到显示面板100的外侧边缘之间的区域由胶水填充,再在低温下对胶水固化,形成涂胶层500,然后通过激光对涂胶层500和显示面板100进行一体化切割,以实现窄边框的需求。
第二种方式,在上述步骤S04之后,步骤S05之前,所述方法还包括:
步骤S041、如图8所示,在所述第一区域、所述保护盖板200的外侧边缘侧面以及所述显示面板100的外侧边框侧面涂胶,形成涂胶层500,并对所述涂胶层500固化,通过所述涂胶层500对显示面板100进行保护。
应当理解的是,以上仅是对于所述涂胶层500的具体实现方式的示例性说明,在实际应用中,所述涂胶层500的实现方式不限于此。
此外,在一些示例性的实施例中,如图4所示,所述第一边框区110的边框宽度比所述第二边框区210的边框宽度大0.2~1.0mm,也就是,所述保护盖板200内缩0.2~1.0mm。
此外,本公开实施例还提供了一种拼接显示屏,该拼接显示屏由本公开实施例提供的拼接显示屏的制造方法制造得到。
如图7所示,所述拼接显示屏包括至少两个相互拼接的子显示屏,所述子显示屏包括贴合一起的显示面板100和保护盖板200,所述子显示屏包括显示区AA,所述显示面板100包括位于所述显示区AA外围的第一边框区110,所述保护盖板200包括位于所述显示区AA外围的第二边框区210;所述第一边框区110的边框宽度大于或等于所述第二边框区210的边框宽度。
由以上可知,相较于相关技术中保护盖板200外扩设计的方案,通过将 子显示屏中的保护盖板200的第二边框区210尺寸设计为比显示面板100的第一边框区110的尺寸窄,也就是说,保护盖板200的外形尺寸内缩,相较于相关技术中保护盖板200外扩设计的方案来说,能够减小拼接缝宽度,实现窄边框需求,提升显示效果。
在一些示例性的实施例中,所述第一边框区110的边框宽度比所述第二边框区210的边框宽度大0.2~1.0mm,也就是,所述保护盖板200内缩尺寸为0.2~1.0mm。当然可以理解的是,对于所述保护盖板200的内缩尺寸不限定。
在一些示例性的实施例中,所述显示面板100的第一边框区110在面向所述保护盖板200的一侧面包括超出所述保护盖板200边缘的第一区域,在所述第一区域以及所述保护盖板200的边缘侧面涂有涂胶层500。
上述方案中,由于保护盖板200进行内缩设计,各子显示屏中显示面板100的外侧边缘会与保护盖板200的外侧边缘之间有一定空白区域,也就是说,如图5所示,所述显示面板100的第一边框区110在面向所述保护盖板200的一侧面包括超出所述保护盖板200边缘的第一区域,在该第一区域内可通过胶水填充,形成涂胶层500。
此外,在一些示例性的实施例中,如图7所示,所述涂胶层500的外侧边缘侧面与所述显示面板100的第一边框区110的外侧边缘侧面齐平。其中这里所述涂胶层500的外侧边缘侧面是指,所述涂胶层的远离显示区的一侧边缘的侧面,所述显示面板的第一边框区的外侧边缘侧面是指,所述显示面板的第一边框区的远离显示区的一侧边缘的侧面。
此外,在另一些示例性的实施例中,如图8所示,所述涂胶层500还涂覆在所述显示面板100的外侧边缘侧面。
本公开实施例所提供的拼接显示屏中,至少两个相互拼接的所述子显示屏之间的拼接缝宽度D为:D=D1+D2+D△,其中,D1为相邻两个子显示拼中的一个子显示屏中所述第一边框区110的边框宽度;D2为相邻两个子显示拼中的另一个子显示屏中所述第一边框区110的边框宽度;D△为相邻两个子显示屏的拼接组装公差值。
相关技术中拼接显示屏的拼接缝宽度D’为:D’=D1’+D2’+D△,其 中,D1’为相邻两个子显示拼中的一个子显示屏中保护盖板的外扩边框宽度;D2’为相邻两个子显示拼中的另一个子显示屏中保护盖板的外扩边框宽度;D△为相邻两个子显示屏的拼接组装公差值,由于D1’大于D1,D2’大于D2,由此可见,本公开实施例提供的拼接显示屏相较于相关技术中拼接显示屏来说,拼接缝尺寸减小,提升显示效果。
