本发明的实施方式
请参照附图中的图式,其中相同的组件符号代表相同的组件。以下的说明是基于所例示的本申请具体实施例,其不应被视为限制本申请未在此详述的其它具体实施例。
请参照图1和图2,图1为本申请实施例的制作触控显示面板的方法的流程图;图2为实现本申请实施例的制作触控显示面板的方法的系统结构示意图。其中,触控显示面板的结构,可参考图3。
本申请实施例的制作触控显示面板的方法,其包括:
步骤S1:关闭进气阀和抽气阀,所述进气阀连接在气体存储器和所述生产腔体之间,所述抽气阀连接在所述生产腔体和抽气装置之间;
步骤S2:提供触控显示模组,并将所述触控显示模组放置在生产腔体内;所述触控显示模组包括显示面板和设置在所述显示面板上的触控导电层,所述触控导电层裸露在外;
步骤S3:对所述生产腔体进行抽真空处理;
步骤S4:对所述生产腔体进行气体充灌处理,所述气体具有非氧化特性;
步骤S5:在所述触控显示模组上进行框贴工艺,形成触控显示面板。
下面结合图1和图2详细说明本实施例的制作触控显示面板的方法的具体流程。
在步骤S1中,关闭进气阀14和抽气阀15。进气阀14连接在气体存储器11和生产腔体12之间。抽气阀15连接在生产腔体12和抽气装置13之间。
关闭进气阀14和抽气阀15,使得生产腔体12具有一个密闭的环境。随后转入步骤S2。
在步骤S2中,提供触控显示模组,并将触控显示模组放置在生产腔体12内。触控显示模组包括显示面板和设置在显示面板上的触控导电层,触控导电层裸露在外。
其中触控显示模组是形成触控显示面板的基础结构。将触控显示模组放置在生产腔体12内,是为了进行框贴工艺,以形成触控显示面板。随后转入步骤S3。
在步骤S3中,对生产腔体12进行抽真空处理。
具体的,打开抽气阀15,抽气装置13对生产腔体12进行抽气处理,当生产腔体12内的当前气压值达到第一压力值时,关闭抽气阀15。第一压力值小于当前环境的大气压值。
其中使生产腔体12的当前气压值达到第一压力值,是为了生产腔体12的内的气压和当前环境的气压形成差异值,促使生产腔体12处于负压的状态下。可选的,进行抽气后,生产腔体12内具有氧化特性的气体均为抽离出生产腔体12,为后续的框贴工艺作准备。
需要说明的是,具有氧化特性的气体,就是具有能氧化金属的气体,比如氧气、臭氧等。另外,生产腔体12内的当前气压值由流量气压计16测得。流量气压计16连通生产腔体12。
随后转入步骤S4。
在步骤S4中,对生产腔体12进行气体充灌处理,所述气体具有非氧化特性。
具体的,打开进气阀14,气体存储器11向生产腔体充灌气体。当生产腔体12内的当前气压值达到第二压力值时,关闭进气阀14。第二压力值小于当前环境的大气压值。
其中使生产腔体12的当前气压值达到第二压力值,是为了生产腔体12的内的气压和当前环境的气压形成差异值,促使生产腔体12处于相对负压的状态下。可选的,进行充气后,生产腔体12内存有具有非氧化特性的气体,为后续的框贴工艺作准备。可选的,气体为氮气或惰性气体,但不限于此。
另外,生产腔体12内的当前气压值由流量气压计16测得。需要说明的是,非氧化特性为不具有氧化导电金属的性质,比如氮气、惰性气体等。
随后转入步骤S5。
在步骤S5中,在触控显示模组上进行框贴工艺,形成触控显示面板。
具体的,在生产腔体12内,依次采用密封框和盖板进行贴合在触控显示模组上。使得盖板、密封框和触控导电层形成一密封空间,而密封空间内充装有非氧化性气体。
另外,由于,密封空间是在密封的条件下形成,即在密封的生产腔体12内形成,而生产腔体12内的气压小于当前环境的气压,从而触控显示面板形成的填充非氧化性气体的密封空间的气压也小于当前环境气压。因此,在离开生产腔体12后,触控显示面板的盖板会向密封空间方向发生凹陷,缩小盖板和触控导电层的间隙值。
而且,将触控显示模组处在密封的非氧化特性的生产腔体12中,使得在进行框贴工艺时,触控显示面板的触控导电层上无需保护层,可通过填充非氧化性气体的密封空间隔绝水气和氧气,避免触控导电层氧化,节省了材料和工艺步骤。
这样即完成了本实施例的触控显示面板的制作过程。
请参照图2,本申请涉及一种制作触控显示面板的系统,其包括生产腔体12、气体存储器11、抽气装置13、抽气阀进气阀14、抽气阀15和流量气压计16。
具体的,生产腔体12用于进行触控显示面板的框贴工艺。

进气阀14设置在生产腔体12和气体存储器11之间,用于控制进气量。
抽气阀15设置在生产腔体12和抽气装置13之间,用于控制排气量。
流量气压计16连通于生产腔体12,用于检测生产腔体12内的当前气压值。

具体的,触控导电层102设置在显示面板101上。触控导电层102裸露在外。密封框103设置在触控导电层102的四周边缘上。盖板104设置在密封框103上。
触控导电层102、密封框103和盖板104界定形成一密封空间105。密封空间105中填充具有非氧化特性的气体。可选的,气体为氮气或惰性气体。
本实施例的触控显示面板100通过密封空间105的设置,使得触控显示面板的触控导电层102上无需保护层,可通过填充非氧化性气体的密封空间105隔绝水气和氧气接触触控导电层,避免触控导电层氧化,节省了材料和工艺步骤。
另外,密封空间105内的压力值小于当前环境的大气压力值,使得盖板104向密封空间105的方向凹陷,进而缩小了盖板104和触控导电层102之间的间隙值。
本实施例的触控显示面板100的制作方法,请参照上述实施例的制作触控显示面板的方法的具体内容。
相较于现有技术的触控显示面板生产工艺,本申请的制作触控显示面板的方法将触控显示模组处在密封的非氧化特性的生产腔体中,在进行框贴工艺时,盖板、密封框和触控导电层形成的密封空间不具有氧化性气体,使得触控显示面板的触控导电层上无需保护层,也能隔绝水气和氧气接触触控导电层,避免触控导电层氧化,节省了材料和工艺步骤;另外,解决了现有的触控显示面板在生产制造中效率慢且成本较高的技术问题。
以上所述,对于本领域的普通技术人员来说,可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形,而所有这些改变和变形都应属于本发明后附的权利要求。
