具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本发明所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
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。
如图1所示，一种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。
通常，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14一侧的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。
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。
从而，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。
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。
本发明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，静电传导膜层被配置来传导显示模组产生的静电。
实施例一
如图3所示，本实施例提供了一种显示模组，包括：保护盖板10、显示面板1314、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。显示面板1314包括相对设置的阵列基板14和对向基板13。对向基板13例如为彩膜基板。当然，彩膜层也可不设置在对向基板上。保护盖板10例如为透明基板，例如可为玻璃基板，但不限于此。
例如，显示面板上设置保护盖板10。静电传导膜层31设置在保护盖板10上，并位于保护盖板10朝向对向基板13的一侧。例如，静电传导膜层31可整面覆盖保护盖板。导电部件32被配置来电连接静电传导膜层31和终端外壳33。
如图3所示，本实施例中的显示模组还可包括背光模组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的设计可参照通常设计，这里不再赘述。
例如，本实施例中的终端外壳33可与外界大地相连通，终端外壳33的设计也可参照通常设计，例如，本实施例中的终端外壳可为手机中框，即手机A壳。
例如，本实施例中的静电传导膜层31覆盖整个保护盖板10，当本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，与通常的静电释放路径相比，本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。当然，也可以通过构图等工艺形成静电传导膜层的图形，本实施例对此不作限定。
例如，本实施例中的静电传导膜层的材料为透明导电材料，透明导电材料例如包括金属、氧化铟锡(ITO)等，但不限于此。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，静电传导膜层的电阻值可根据工艺以及实际需要进行设定，本实施例不对静电传导膜层的电阻值做限定。
例如，如图3所示，本实施例可以通过镀膜的方式在保护盖板10朝向对向基板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朝向对向基板13的一侧设置静电传导膜层31，例如，通过喷涂的方式在保护盖板10朝向对向基板13的一侧喷涂一层静电传导膜层31。
例如，本实施例中的导电部件32为导电泡棉或导电胶，当然，本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。
本实施例通过在保护盖板朝向对向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，因此本实施例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，与通常技术的静电释放路径相比，本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，当本实施例中的显示模组设置有按键柔性电路板41时，即本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，与通常技术的静电释放路径相比，本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之间可以通过点胶技术进行点胶，保护盖板10与终端外壳33可通过点胶技术点的胶42连接。
例如，本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，本实施例一示例中的显示模组还可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被配置来电连接静电传导膜层31和终端外壳33。例如，本实施例中的导电部件32可为导电泡棉或导电胶，当然，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，与通常技术的静电释放路径相比，本示例提供的显示模组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。
例如，本实施例中的静电传导膜层的材料可为透明导电材料，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，静电传导膜层的电阻值可根据工艺以及实际需要进行设定，本实施例不对静电传导膜层的具体电阻值做限定。
本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，本实施例一示例中的触控显示模组，包括设置在阵列基板14和对向基板13之间的触控电极51，本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；静电传导膜层31位于保护盖板10朝向对向基板13的一侧；导电部件32被配置来电连接静电传导膜层31和终端外壳33。
本示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，与通常技术的静电释放路径相比，本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。
例如，如图6所示，本实施例设置在阵列基板和对向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对向基板的一侧，也可以设置在对向基板朝向阵列基板的一侧，自电容触控电极可参照通常设计，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对向基板的一侧，也可以将驱动电极和感应电极均设置在对向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对向基板的一侧，将感应电极设置在对向基板朝向阵列基板的一侧，互电容触控电极可参照通常设计，这里不再赘述。
如图7所示，本实施例一示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被配置来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。
此时本示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，与通常技术的静电释放路径相比，本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。
实施例三

综上所述，本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，该静电传导膜层被配置来传导显示模组产生的静电，因此本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，与通常技术通过导电的贴合胶和银胶释放静电相比，本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。
本公开的实施例中，同一附图标记代表同一含义。在不冲突的情况下，本发明的同一实施例及不同实施例中的特征可以相互组合。
