Abstract

本发明公开了一种显示模组、显示装置,用以提高产品的抗静电能力,提高产品的使用性能以及竞争力。显示模组,包括:保护盖板、显示面板,其中,还包括静电传导膜层,所述静电传导膜层位于所述保护盖板朝向所述显示面板的一侧,用于传导所述显示模组产生的静电。

Description

一种显示模组、显示装置
技术领域
本发明涉及显示技术领域,尤其涉及一种显示模组、显示装置。
背景技术
显示模组包括显示面板和背光模组,当显示模组的静电较大时,静电会使显示面板四周线路断路,导致显示异常,如:发红、发蓝、异常显示甚至无法显示等。触控显示模组包括触控显示面板和背光模组,当触控显示模组的静电较大时,静电会将触控显示模组的集成电路(IC)烧坏或使触控显示面板四周线路断路,导致显示异常,如:发红、发蓝、甚至无法显示等。
如图1所示,现有技术显示模组包括相对设置的阵列基板14和彩膜基板13,设置在彩膜基板13背向阵列基板14一侧的上偏光片12,设置在阵列基板14背向彩膜基板13一侧的下偏光片15,对阵列基板14和彩膜基板13进行保护的保护盖板10,将保护盖板10与上偏光片12粘合的透明光学胶11,将上偏光片12与彩膜基板13贴合的贴合胶18。
现有技术针对该显示模组采用的防静电(Electro-Static discharge,ESD)方法为:通过在贴合胶18中掺入导电粒子17防止ESD,此时的贴合胶18变为导电的贴合胶,导电的贴合胶和银胶16电连接,通过银胶16与阵列基板14侧IC电路(图中未示出)中的接地走线连接,静电通过导电的贴合胶和银胶的导电通路进行释放,从而起到防ESD的作用。
现有技术采用上述方法既能对显示模组起到防ESD的作用,也能对触控显示模组起到防ESD的作用,但在实际使用过程中,上偏光片12和贴合胶18易受外界温湿度环境的影响,受外界温湿度环境的影响后,上偏光片12和贴合胶18会收缩,如图2所示,贴合胶18收缩后会与银胶16分离,产生间隙20,此时导电的贴合胶和银胶的导电通路断开,产生的静电不能很好的得到释放,降低了ESD的防护功能。
综上所述,现有技术采用在贴合胶中掺入导电粒子防止ESD时,在实际使用过程中易受外界温湿度环境的影响,降低ESD的防护功能。
发明内容
本发明实施例提供了一种显示模组、显示装置,用以提高产品的抗静电能力,提高产品的使用性能以及竞争力。

具体实施方式
本发明实施例提供了一种显示模组、显示装置,用以提高产品的抗静电能力,提高产品的使用性能以及竞争力。
为了使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明作进一步地详细描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例,都属于本发明保护的范围。
本发明具体实施例提供了一种显示模组,包括:保护盖板、显示面板、静电传导膜层,静电传导膜层位于保护盖板朝向显示面板的一侧,用于传导显示模组产生的静电。
下面结合附图详细介绍本发明具体实施例提供的显示模组包括的静电传导膜层传导显示模组产生的静电的过程。
附图中各膜层厚度和区域大小、形状不反应各膜层的真实比例,目的只是示意说明本发明内容。
实施例一:
如图3所示,本发明具体实施例提供了一种显示模组,包括:保护盖板10、显示面板、静电传导膜层31、以及设置在保护盖板10和显示模组所属的终端外壳33之间的导电部件32;其中,显示面板包括相对设置的阵列基板14和彩膜基板13;
静电传导膜层31位于保护盖板10朝向彩膜基板13的一侧;
导电部件32用于电连接静电传导膜层31和终端外壳33。
如图3所示,本发明具体实施例中的显示模组还包括背光模组34和模组柔性电路板(Flexible Printed Circuit,FPC)35,背光模组34和模组柔性电路板35的具体设计与现有技术相同,这里不再赘述。
本发明具体实施例中的终端外壳33与外界大地相连通,终端外壳33的具体设计也与现有技术相同,具体地,本发明具体实施例中的终端外壳为手机中框,即手机A壳。
优选地,本发明具体实施例中的静电传导膜层31覆盖整个保护盖板10,当本发明具体实施例中的显示模组产生静电时,产生的静电沿着静电传导膜层31、导电部件32和终端外壳33进行释放,与现有技术的静电释放路径相比,本发明具体实施例在释放静电时不受外界温湿度环境的影响,能够提高产品的抗静电能力。
本发明具体实施例中的静电传导膜层覆盖整个保护盖板,当显示模组产生静电时,静电传导膜层能够更好的起到传导静电的作用。另外,由于静电传导膜层覆盖整个保护盖板,不需要通过构图等工艺形成静电传导膜层的图形,因此,该静电传导膜层在制作时较简单,并且制作成本也相对较低,同时制作过程也不会对整个显示模组造成较大的影响,能够保证显示模组的良率。
优选地,本发明具体实施例中的静电传导膜层的材料为透明导电材料,该静电传导膜层的方块电阻值为108Ω/□到1010Ω/□,方块电阻值在该范围内的静电传导膜层在实际生产过程中能够更好的传导显示模组产生的静电,并且整面覆盖保护盖板的静电传导膜层的方块电阻值为108Ω/□到1010Ω/□时,不会对显示模组的显示造成影响。在实际生产过程中,静电传导膜层的具体电阻值需要根据工艺以及实际需要进行设定,本发明具体实施例不对静电传导膜层的具体电阻值做限定。
具体实施时,如图3所示,本发明具体实施例可以通过镀膜的方式在保护盖板10朝向彩膜基板13的一侧镀一层静电传导膜层31,当然,在实际生产过程中,还可以通过其它方式在保护盖板10朝向彩膜基板13的一侧设置静电传导膜层31,如:通过喷涂的方式在保护盖板10朝向彩膜基板13的一侧喷涂一层静电传导膜层31。
优选地,本发明具体实施例一中的导电部件32为导电泡棉或导电胶,在实际设计时,本发明具体实施例中的导电部件还可以选择其它的导电材料,这里不对导电部件的具体材料做限定。
本发明具体实施例一通过在保护盖板朝向彩膜基板的一侧设置静电传导膜层,以及在保护盖板和终端外壳之间设置导电部件,在实际生产中,由于终端外壳与外界大地相连通,因此本发明具体实施例一中的显示模组产生的静电沿着静电传导膜层、导电部件和终端外壳进行释放,与现有技术的静电释放路径相比,本发明具体实施例在释放静电时不受外界温湿度环境的影响,能够提高产品的抗静电能力。
实施例二:
如图4所示,本发明具体实施例中的显示模组还包括按键柔性电路板41,按键柔性电路板41用于电连接静电传导膜层31和显示模组包括的模组柔性电路板35。本发明具体实施例中按键柔性电路板41的具体结构设计与现有技术相同,现有技术的按键柔性电路板41与保护盖板10相接触。
如图4所示,当本发明具体实施例中的显示模组设置有按键柔性电路板41时,即本发明具体实施例中的显示模组需要绑定按键柔性电路板41时,若显示模组产生静电,产生的静电能够通过静电传导膜层31、按键柔性电路板41上的接地(GND)线路和模组柔性电路板35上的GND线路进行释放,与现有技术的静电释放路径相比,本发明具体实施例在释放静电时不受外界温湿度环境的影响,能够提高产品的抗静电能力。这种情况下,保护盖板10与终端外壳33之间可以通过现有技术的点胶技术进行点胶,保护盖板10与终端外壳33通过点胶技术点的胶42连接。
优选地,本发明具体实施例中的静电传导膜层31覆盖整个保护盖板10,当显示模组产生静电时,静电传导膜层能够更好的起到传导静电的作用。另外,由于静电传导膜层覆盖整个保护盖板,不需要通过构图等工艺形成静电传导膜层的图形,因此,该静电传导膜层在制作时较简单,并且制作成本也相对较低,同时制作过程也不会对整个显示模组造成较大的影响,能够保证显示模组的良率。
如图5所示,本发明具体实施例中的显示模组还包括设置在保护盖板10和终端外壳33之间的导电部件32,导电部件32用于电连接静电传导膜层31和终端外壳33。优选地,本发明具体实施例二中的导电部件32为导电泡棉或导电胶,在实际设计时,导电部件还可以选择其它的导电材料,这里不对导电部件的具体材料做限定。
如图5所示,当显示模组产生静电时,产生的静电既可以沿着静电传导膜层31、导电部件32和终端外壳33进行释放,又可以沿着静电传导膜层31、按键柔性电路板41上的GND线路和模组柔性电路板35上的GND线路进行释放,这样,能够保证显示模组产生的静电得到更好的释放,与现有技术的静电释放路径相比,本发明具体实施例在释放静电时不受外界温湿度环境的影响,能够提高产品的抗静电能力。
优选地,本发明具体实施例中的静电传导膜层的材料为透明导电材料,该静电传导膜层的方块电阻值为108Ω/□到1010Ω/□,当然,在实际生产过程中,静电传导膜层的具体电阻值需要根据工艺以及实际需要进行设定,本发明具体实施例不对静电传导膜层的具体电阻值做限定。
具体地,本发明具体实施例中的显示模组可以为具有触控功能的触控显示模组,下面结合附图介绍本发明具体实施例中的触控显示模组产生的静电的释放过程。
如图6所示,本发明具体实施例中的触控显示模组,包括设置在阵列基板14和彩膜基板13之间的触控电极51,本发明具体实施例提供的触控显示模组还包括静电传导膜层31,以及设置在保护盖板10和终端外壳33之间的导电部件32;其中,静电传导膜层31位于保护盖板10朝向彩膜基板13的一侧;导电部件32用于电连接静电传导膜层31和终端外壳33。
本发明具体实施例中的触控显示模组产生的静电可以沿着静电传导膜层31、导电部件32和终端外壳33进行释放,与现有技术的静电释放路径相比,本发明具体实施例在释放静电时不受外界温湿度环境的影响,能够提高产品的抗静电能力。
具体实施时,如图6所示,本发明具体实施例设置在阵列基板和彩膜基板之间的触控电极51可以为自电容触控电极,也可以为互电容触控电极。当触控电极为自电容触控电极时,自电容触控电极可以设置在阵列基板朝向彩膜基板的一侧,也可以设置在彩膜基板朝向阵列基板的一侧,自电容触控电极的具体设计方式与现有技术相同,这里不再赘述。
当触控电极为互电容触控电极时,可以将驱动电极和感应电极均设置在阵列基板朝向彩膜基板的一侧,也可以将驱动电极和感应电极均设置在彩膜基板朝向阵列基板的一侧,还可以将驱动电极设置在阵列基板朝向彩膜基板的一侧,将感应电极设置在彩膜基板朝向阵列基板的一侧,互电容触控电极的具体设计方式与现有技术相同,这里不再赘述。
如图7所示,本发明具体实施例中的触控显示模组还包括按键柔性电路板41,柔性电路板41用于电连接静电传导膜层31和显示模组包括的模组柔性电路板35。
此时本发明具体实施例中的触控显示模组产生的静电能够通过静电传导膜层31、按键柔性电路板41上的GND线路和模组柔性电路板35上的GND线路进行释放,与现有技术的静电释放路径相比,本发明具体实施例在释放静电时不受外界温湿度环境的影响,能够提高产品的抗静电能力。
另外,本发明具体实施例中的触控显示模组还可以包括设置在保护盖板10和终端外壳33之间的导电部件32,导电部件32的设置可参照图5所示,此时本发明具体实施例中的触控显示模组产生的静电既可以沿着静电传导膜层31、导电部件32和终端外壳33进行释放,又可以沿着静电传导膜层31、按键柔性电路板41上的GND线路和模组柔性电路板35上的GND线路进行释放,与现有技术的静电释放路径相比,本发明具体实施例在释放静电时不受外界温湿度环境的影响,能够提高产品的抗静电能力。
本发明具体实施例还提供了一种显示装置,该显示装置包括上述的显示模组,该显示装置可以为液晶面板、液晶显示器、液晶电视、有机发光二极管(Organic LightEmitting Diode,OLED)面板、OLED显示器、OLED电视或电子纸等显示装置。
综上所述,本发明具体实施例提供一种显示模组,包括:保护盖板、显示面板,其中,还包括静电传导膜层,静电传导膜层位于保护盖板朝向显示面板的一侧,用于传导显示模组产生的静电。由于本发明具体实施例在保护盖板朝向显示面板的一侧设置静电传导膜层,该静电传导膜层用于传导显示模组产生的静电,因此本发明具体实施例中的显示模组产生的静电可以通过静电传导膜层进行释放,与现有技术通过导电的贴合胶和银胶释放静电相比,本发明具体实施例在释放静电时,静电传导膜层不受外界温湿度环境的影响,能够提高产品的抗静电能力,进而提高产品的使用性能以及竞争力。
显然,本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样,倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内,则本发明也意图包含这些改动和变型在内。
