Description

一种显示模组、显示面板、显示装置及电子设备 技术领域
本申请涉及显示技术领域，尤其涉及一种显示模组、显示面板、显示装置及电子设备。
背景技术
在目前的电子产品消费市场中，诸如手机、电视机、电脑显示器等电子产品已逐渐采用显示装置窄边框化的设计，以获得较高的屏占比，提升视觉观感。对显示装置中的显示模组而言，为使显示模组满足显示装置窄边框化需求，目前的常用的一种解决方案为栅极驱动集成于阵列基板(Gate on Array，GOA)技术，GOA技术可将栅极驱动线路集成于阵列基板上，与传统布线方式相比节省了所需的边框空间，从而可缩小显示模组边缘区域的宽度，进而使显示装置的边框窄化。
GOA电路中包括薄膜晶体管(Thin Film Transistor，TFT)器件、电容等静电敏感器件，且位于阵列基板的边缘，发生静电击伤的风险较大，因此GOA电路对静电防护的要求较高。目前常用的GOA电路静电防护方法为在GOA电路上覆盖保护层，参见图1所示，图1为一种常见的显示模组的局部结构示意图，该显示模组包括阵列基板01、彩膜基板02和胶框03，阵列基板01与彩膜基板02通过胶框03连接，阵列基板01上设有GOA电路011和覆盖GOA电路的保护层012，在显示模组上产生静电放电时，保护层012具有一定的静电阻挡作用，可降低GOA电路011被静电直接击中的概率，以实现对GOA电路011的静电防护功能。静电放电一般由静电积累导致，然而，现有的显示模组仅能在静电放电时阻挡静电击中GOA电路，不能减少静电的积累，在显示模组上的静电累计到一定程度时易产生静电放电，而显示模组在处于易发生静电放电的使用环境时，其安全隐患仍然较高，导致显示模组的可靠性下降。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
本申请提供一种显示模组、显示面板及电子设备，用以解决现有技术中的显示面板中的胶框与保护层的连接位置处易发生脱离，进而导致显示面板产品的可靠性降低的问题。
以下，对本申请中的部分用语进行解释说明，以便与本领域技术人员理解。
多个，是指两个或两个以上。另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
参见图2和图3a、图3b所示，图2为本申请实施例提供的一种显示模组在显示区域的局部剖面示意图，图3a、图3b为图2所示的显示模组的结构示意图。如图2所示，该显示模组包括第一基板10、第二基板20、胶框30，如图3a所示，该显示模组还包括静电释放机构40。
继续参见图2所示，第一基板10和第二基板20通过胶框30对盒连接，参见图3b所示，第一基板10、第二基板20和胶框30形成三个防护面101、102和103，三个防护面101、102和103是由第一基板10、第二基板20和胶框30位于同一侧的外侧面拼接形成的平面，以防护面101为例，参见图2所示，防护面101由第一基板10的外侧面13、第二基板20的外侧面21和胶框30的外侧面31拼接形成。需要说明的是，本实施例中，第一基板10的长度大于第二基板20的长度，在第一基板10超出第二基板20的台阶状部分不能形成防护面，而在其他实施方式中，当第一基板10和第二基板10的长度相等时，则第一基板10、第二基板20和胶框30可拼接形成四个防护面。
需要说明的是，具体实施中，第一基板10可为阵列基板，第二基板20可为彩膜基板，该显示模组还包括设置于第一基板10上的TFT层、配向层等层级结构，以及 设置于第二基板20上的黑矩阵层、彩膜层等层级结构，以及设置于第一基板10和第二基板20之间的液晶层和隔垫物等结构。
如图2所示，第一基板10朝向第二基板20的一侧设有栅极驱动电路11，参见图3b所示，第一基板10上在与防护面101、102平行的两个侧边位置处各设有一个栅极驱动电路11。需要说明的是，栅极驱动电路11的分布区域一般为条状，并位于第一基板10的外围电路区内的两侧，且平行于第一基板10的两个侧边，图3b所示的两个栅极驱动电路11的分布区域的长度方向即为栅极驱动电路11的分布区域的延伸方向，图2为显示模组在显示区域的截面示意图，栅极驱动电路11仅示出一部分。
继续参见图3a所示，静电释放机构40包括接地电极41和与接地电极41连接的导电层42，接地电极41设置于第一基板10。结合图2所示，导电层42包括第一导电层421和第二导电层422，第一导电层421和第二导电层422为一体式结构，参见图3a、图3b所示，第一导电层421可以设置于与栅极驱动电路的分布区域的延伸方向平行的两个防护面101、102、以及与栅极驱动电路的分布区域的延伸方向垂直的防护面103上，图3a中仅示出防护面101上的导电层。结合图2所示，以防护面101对应的导电层42为例，第一导电层421的面积大于栅极驱动电路11在防护面101上的投影的面积，且栅极驱动电路11在防护面101上的投影被第一导电层421完全覆盖。同理，在防护面102上，第一导电层421的面积大于栅极驱动电路11在防护面102上的投影的面积，且栅极驱动电路11在防护面102上的投影被第一导电层421完全覆盖；在防护面103上，第一导电层421的面积大于栅极驱动电路11在防护面102上的投影的面积，且栅极驱动电路11在防护面102上的投影被第一导电层421完全覆盖。
继续参见图2所示，以防护面101对应的导电层42为例，第二导电层422设置于第一基板10背离第二基板20的一侧，且第二导电层422覆盖栅极驱动电路11在第一基板10背离第二基板20的一侧的投影的一部分。同理，防护面102对应的第二导电层422设置于第一基板10背离第二基板20的一侧，且第二导电层422覆盖栅极驱动电路11在第一基板10背离第二基板20的一侧的投影的一部分；防护面103对应的第二导电层422设置于第一基板10背离第二基板20的一侧，且第二导电层422覆盖栅极驱动电路11在第一基板10背离第二基板20的一侧的投影的一部分。
本实施例中，导电层42与接地电极41的具体连接方式参见图3a所示，接地电极41例如可以设置在第一基板10超出第二基板20的台阶状部分上，导电层41的一部分弯折并贴附在接地电极41上方，在第一基板10上可设置过孔，以使接地电极41和导电层42相重叠的部分经过孔进行连接。其他实施方式中，还可将接地电极41直接形成在第一基板10的外表面，使接地电极41与导电层42之间直接接触。或，导电层42与接地电极41之间也可不设置相重叠的部分，而通过导线将导电层42与接地电极41进行连接。接地电极的具体位置以及与导电层的连接方式在此不做限定，只要保证两者连接的任一方式均在本发明实施例的保护范围内。
具体实施中，导线可采用导电银浆形成。
具体实施中，第一导电层421和第二导电层422也可为分体式结构，则第一导电层421和第二导电层422可以分别与接地电极41进行连接。图2-图3b所示结构的显示模组中，在任一防护面所在位置产生静电电荷积累时，由于第一导电层421与接地电极41连接，则电荷会传导至第二导电层422，可降低静电电荷的持续积累而产生静 电放电现象的概率。而在该防护面位置处产生静电放电现象时，电流在击中第二导电层时，会通过第二导电层422传导至接地电极41，从而实现静电的释放，可降低静电放电击中栅极驱动电路11的概率。同理，在第一基板10背离第二基板20的一侧的第二导电层422也可降低静电电荷的持续积累而产生静电放电现象的概率、以及降低静电放电击中栅极驱动电路11的概率。因此，本申请实施例提供的显示模组可通过静电释放机构减少显示模组上的静电积累，从而可降低由静电积累带来的安全风险，提高显示模组的可靠性。
另外，由于导电层42可实现对栅极驱动电路11的静电防护作用，本申请实施例提供的显示模组中，在栅极驱动电路11上无需完全覆盖用于进行静电防护的保护层12，可减小保护层12对栅极驱动电路11的覆盖面积。具体参见图2所示，第一基板10朝向第二基板20的一侧设有栅极驱动电路11和保护层12，保护层12位于栅极驱动电路11朝向第二基板20的一侧，并覆盖栅极驱动电路11的一部分。
与图1所示的现有技术中的显示模组相比，本申请实施例提供的显示模组中的保护层12在不改变胶框30与第一基板10的连接位置和接触面积的情况下，可减小胶框30与保护层12之间的接触面积，使胶框30与第一基板10之间的粘接强度增大，进而使胶框30与第一基板10之间不易脱离，可提高显示模组的可靠性。
具体实施中，应根据第一基板10、第二基板20和胶框30上易产生静电击伤的区域的分布情况，对导电层42在第一基板10、第二基板20和胶框30上的覆盖面积大小和位置进行设置。静电击伤区域的分布情况可根据显示模组的使用场合和环境进行确定，也可通过实验测试进行确定。导电层42应覆盖第一基板10、第二基板20和胶框30上易产生静电击伤的区域，以降低栅极驱动电路11被静电击伤的概率。
图2所示结构的显示模组中，第一导电层421在防护面上的覆盖面积较大，可对防护面上的大范围静电击伤路径进行防护。具体实施中，还可根据防护面上易产生静电击伤的区域的分布，对第一导电层421的面积大小和位置进行调整。
具体例如，可使第一导电层421完全覆盖整个防护面，也可使第一导电层421仅覆盖防护面的一部分。同理，第二导电层422的面积大小覆盖位置也应根据第一基板10背离第二基板20一侧的易发生静电击伤的区域的分布情况进行设置。而在其他实施方式中，也可仅在防护面上设置导电层42，或在防护面、第一基板10背离第二基板20的一侧和第二基板20背离第一基板10的一侧均设置导电层42。以下结合图4a-图6具体说明导电层42的其他设置方式，需要说明的是，图4a-图6中仅以防护面101对应的导电层为例，而在具体实施中，任一防护面上的导电层的设置方法均可按照防护面101所示进行设置。
参见图4a所示，图4a为本申请实施例提供的另一种结构的显示模组的局部剖面示意图，在该结构的显示模组中，导电层42仅设置于防护面101，且未完全覆盖整个防护面101，导电层42的面积大小等于栅极驱动电路11在防护面101上的投影，并覆盖栅极驱动电路11在防护面101上的投影。其他实施方式中，根据防护面101上易产生静电击伤区域的分布情况，导电层42的面积还可大于栅极驱动电路11在防护面101上的投影并覆盖栅极驱动电路11在防护面101上的投影，或，导电层42的面积还可小于栅极驱动电路11在防护面101上的投影，并覆盖栅极驱动电路11在防护面101上的投影的一部分。
参见图4b所示，图4b为本申请实施例提供的另一种结构的显示模组的局部剖面示意图，在该结构的显示模组中，导电层42仅设置于防护面101，且未完全覆盖整个防护面101，导电层42未覆盖栅极驱动电路11在防护面101上的投影。
参见图5所示，图5为本申请实施例提供的另一种结构的显示模组的局部剖面示意图，在该结构的显示模组中，导电层42仅设置于防护面101，且完全覆盖整个防护面101。
图4a-图5所示的显示模组中，导电层42的覆盖面积较小，可简化显示模组的结构。
参见图6所示，图6为本申请实施例提供的另一种结构的显示模组的局部剖面示意图，该显示模组中，导电层42包括第一导电层421、第二导电层422和第三导电层423，其中，第一导电层421覆盖整个防护面101，第二导电层422设置于第一基板10背离第二基板20的一侧，第三导电层423设置于第二基板20背离第一基板10的一侧。第二导电层422可覆盖栅极驱动电路11在第一基板10背离第二基板20一侧的投影的一部分，也可完全覆盖栅极驱动电路11在第一基板10背离第二基板20一侧的投影，同理，第三导电层423可覆盖栅极驱动电路11在第二基板20背离第一基板10一侧的投影的一部分，也可完全覆盖栅极驱动电路11在第二基板20背离第一基板10一侧的投影。第一导电层421、第二导电层422和第三导电层423可为一体式结构，也可为分体式结构。
需要说明的是，在图2、图5、图6所示结构的显示模组中，由于导电层42的覆盖面积较大，在显示模组的生产、搬运过程中，还可起到保护第一基板10和第二基板20边缘部分的作用，可降低在显示模组的生产、搬运过程中，第一基板10和第二基板20受到碰撞产生裂纹和崩缺的概率。
在图2-图6所示的显示模组的制备过程中，为使保护层12不覆盖栅极驱动电路11，或仅覆盖栅极驱动电路11的一部分，在形成保护层12的光刻工艺中，应调整保护层12的掩膜板的尺寸，使形成的保护层12不覆盖栅极驱动电路11，或仅覆盖栅极驱动电路11的一部分。
而在胶框30的涂覆过程中，可以设置胶框30的涂覆区域，使胶框30仅覆盖保护层12的一部分，或与保护层12之间无接触，即胶框与保护层在第一基板10上的投影不重叠。具体如图2所示，胶框30仅覆盖保护层12的一部分，或如图4a-图6所示，胶框30与保护层12之间无接触，该结构可进一步窄化显示边框。
本申请实施例提供的显示模组中，接地电极41还可设置于第二基板20，或同时设置于第一基板10和第二基板20，具体实施中，接地电极41可为设置于第一基板10或第二基板20上的公共电极。除图3a所示的导电层42与第一基板10上的接地电极41连接的结构之外，在其他实施方式中，导电层42还可与第二基板20上的接地电极41连接，或同时与第一基板10和第二基板20上的接地电极41连接。
本申请实施例提供的显示模组中，接地电极可为在第一基板10、第二基板20上独立设置的、仅用作静电释放作用的电极，接地电极在制备过程中具体可采用光刻工艺形成，具体实施中，显示模组上的接地电极通过引线或柔性电路板与显示装置内的接地线连接。
由于现有的显示模组中，在阵列基板和彩膜基板上均设有多条公共电极，其他实 施方式中，还可将部分公共电极作为接地电极，实现静电的释放。具体地，分布于显示模组的显示区域内或外围电路区域内的公共电极均可用作接地电极，在实施过程中需根据显示模组的具体电路结构进行选取。则在第一基板10为阵列基板、第二基板20为彩膜基板时，由于彩膜基板上的公共电极通常通过隔垫物与阵列基板上的公共电极连接，在一种具体实施方式中，接地电极41包括设置于第一基板10上的第一接地电极41和设置于第二基板20上的第二接地电极41，第一接地电极41和第二接地电极41连接，导电层42与第一接地电极41连接。该连接方式可不改变显示模组的公共电极的现有结构，简化显示模组的制备工艺。另外，导电层42上的静电和第二基板20上的静电均可通过第一接地电极41进行释放，可进一步提高显示模组的防静电能力。
为减小导电层42的空间占用，进而缩窄显示模组的显示边框，如图2-图6所示，导电层42为薄膜状结构，可减少导电层42在显示模组防护面位置处的空间占用量，进而窄化显示边框的宽度。具体实施中，导电层42的厚度应根据显示模组对静电的防护需求进行设置，其厚度大小应保证静电不能击穿导电层42。
一种具体实施方式中，导电层42为导电胶带。导电胶带可采用导电材料薄膜制成，具体例如铜、铝、金属氧化物、半导体等材料制成的薄膜。贴附导电胶带之前可根据所需防护的易发生静电击伤区域的形状和面积将导电胶带剪裁成对应的形状。
另一种具体实施方式中，导电层42为导电涂层。导电涂层可采用具有导电性能的流体或半流体，例如导电胶、导电银浆等。将具有导电性能的流体或半流体涂覆于所需进行静电防护的区域并使其固化，即可形成所需的形状的导电层42。
基于同一发明构思，本申请还提供了一种显示面板，参见图7所示，包括背光模组200和如上述技术方案中提供的显示模组100。具体实施中，背光模组200包括背光源、导光板、偏光片、反射层等结构。
该显示面板中，其显示模组的胶框30与第一基板10之间不易脱离，可提高显示面板的可靠性。具体原理和实现方式参见上述实施例，不再赘述。
参见图7所示，在设置于第一基板10背离第二基板20一侧的偏光片210的贴附过程中，在将偏光片上的离型膜剥离时，会使偏光片210上产生静电，为降低偏光片210上的静电击伤显示模组中的栅极驱动电路11的概率，一种具体实施方式中，偏光片210与显示模组中的导电层42连接，则在显示面板的生产过程和使用过程中，偏光片210上的静电可传导至导电层42，并通过导电层42传导至接地电极41，以实现偏光片210的静电释放，降低了栅极驱动电路11由于偏光片210产生的静电导致损坏的概率，提高了显示面板的静电防护能力。
具体地，参见图7所示，在导电层42包括设置于第一基板10背离第二基板20的一侧的第二导电层422时，偏光片210的一部分与设置于第一基板10背离第二基板20的一侧的至少一部分第二导电层422具有重合区域，则偏光片210上的静电可直接传导至第二导电层422上，同时还可减小显示面板在栅极驱动电路11所在的侧边产生漏光现象的概率。在导电层42未设置于第一基板10背离第二基板20的一侧时，可通过引线将偏光片210和导电层42进行连接。
基于同一发明构思，本申请实施例还提供了一种显示装置，包括如上述实施例提供的显示面板。具体地，该显示装置可为电脑显示器、电视等。
该显示装置中，其显示模组的胶框30与第一基板10之间不易脱离，可提高显示面板的可靠性。具体原理和实现方式参见上述实施例，不再赘述。
基于同一发明构思，本申请实施例还提供了一种电子设备，包括如上述实施例提供的显示装置。具体地，该电子设备可为手机、平板电脑、笔记本电脑、智能穿戴设备等。
该电子设备中，其显示模组的胶框30与第一基板10之间不易脱离，可提高显示面板的可靠性。具体原理和实现方式参见上述实施例，不再赘述。
显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
