Description

背光模组、显示面板及显示装置 技术领域
本公开的实施例涉及一种背光模组、显示面板及显示装置。
背景技术
背光模组是液晶显示面板中关键的组件之一。通常，背光模组包括光源、背板、设置在背板上且环绕背板的周边的模组边框、以及设置在背板上、模组边框内侧的反射片、导光板、光学膜片等。背光模组的模组边框的内侧可设置由阵列基板、对置基板以及夹设在阵列基板和对置基板之间的液晶层组成的液晶盒。由此，背光模组可为该液晶盒提供具有充足亮度和均匀分布的背光。
在阵列基板的生产工艺中，当薄膜晶体管(Thin Film Transistor，TFT)阵列制作完成之后，会在阵列基板上形成测试线，用于对薄膜晶体管阵列的各类不良发生率进行检测。由于测试线是专门用于测试薄膜晶体管阵列，在随后切割工序中，测试线设计在切割线以外的部分会被切除，切割线以内的部分会被保留。因此，切割后的测试线在阵列基板的边缘处形成断口。
由于切割后的测试线的断口为裸露状态，无法完全封闭绝缘，静电可从切割后的测试线进入阵列基板内部的电路并导致静电释放(Electro-Static Discharge，ESD)发生，破坏阵列基板内部的电路，进而导致显示异常。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开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公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，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，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开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。“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。
为解决阵列基板切割后的测试线静电释放的问题，测试线可采用拐角设计来避免静电进入测试线。下面以测试线设置在阵列基板的右上角为例进行说明。当然，测试线还可设置在阵列基板的其他位置。例如，测试线可设置在阵列基板的左上角或者同时设置在阵列基板的左上角和右上角，本公开在此不作限制。如图1a所示，测试线214设置在阵列基板210的右上角，测试线214可采用图1中矩形虚线框所示的拐角设计；经过切割工艺之后，在阵列基板210的右上角留下切割后的测试线215和“L”形的测试线拐角部分216。由于测试线拐角部分216具有两个断口2160并且这两个断口2160较切割后的测试线215的断口2150距离阵列基板210的右侧边缘更近，可优先吸引靠近阵列基板210的静电，从而可避免静电从切割后的测试线210的断口2150进入阵列基板210内部。
然而，本申请的发明人在研究中认为随着阵列基板内部的电路越来越复 杂，人们对于显示面板窄边框、轻、薄等性能的不断追求，阵列基板留给测试线的位置越来越少。如此，切割后的测试线的断口与阵列基板右侧边缘的距离也越来越近，测试线拐角部分无法发挥防止静电进入切割后的测试线的作用。另外，如图1b所示，即使测试线拐角部分216将电荷吸收，但是由于切割后的测试线215与测试线拐角部分216的距离也越来越近，电荷可从测试线拐角部分216尖锐的部分，例如，测试线拐角部分216的拐角处，进入切割后的测试线215，从而进入阵列基板210内部的电路。再者，本申请的发明人还注意到，当背光模组和液晶盒配合形成显示面板之后，一般会使用静电枪对显示面板的指定区域进行放电，以测试显示面板的抗静电性能。例如，如图2所示，静电枪240对显示面板200的右上角进行放电，这样，静电枪240释放的电荷可从显示面板200的右上角进入切割后的测试线215，从而破坏阵列基板210内部的电路。
本公开的实施例提供一种背光模组、显示面板及显示装置。该背光模组包括模组边框以及设置在模组边框内部的至少一个第一导电尖端结构；第一导电尖端结构包括第一导电尖端，第一导电尖端处于裸露于模组边框的裸露状态。该背光模组依据尖端放电的原理，通过设计导电尖端结构来优先对静电或静电枪释放的电荷进行放电，避免静电或静电枪释放的电荷通过切割后的测试线进入阵列基板内部的电路。
下面结合附图，对本公开实施例提供背光模组、显示面板及显示装置进行说明。
实施例一
本实施例提供一种背光模组，如图3所示，背光模组100具有一出光面150。出光面150为背光模组100的背光(如图中箭头所示)出射的一面。背光模组100包括模组边框110和设置在模组边框110内部的至少一个第一导电尖端结构120。第一导电尖端结构120包括第一导电尖端125，第一导电尖端125处于裸露于模组边框110的裸露状态。需要说明的是，上述的模组边框110内部是指模组边框110的框体内部而并非模组边框110用于放置液晶盒的内侧；上述的裸露于模组边框110的裸露状态是指第一导电尖端125没有被模组边框110的材料所覆盖，例如与模组边框110的表面平齐、或者位于表面之下但通过位于模组边框内的孔洞露出、或者伸出模组边框的表面。
例如，模组边框110内侧还可设置有反射片、导光板、光学膜片等(图中 未示出)。背光模组100的出光面侧也就是导光板的出光面侧。从导光板出射的背光(如图3中的箭头所示)可以提供给设置在模组边框110内侧的液晶盒作为光源。
例如，模组边框110的材料可包括绝缘的有机材料或无机材料；第一导电尖端结构120的材料可包括金属。
例如，为了增强第一导电尖端125吸引电荷的能力，第一导电尖端125的材料可包括低阻抗的金属，例如，银或铜。
在本实施例提供的背光模组中，由于背光模组100包括具有第一导电尖端125的第一导电尖端结构120，依据尖端放电原理，静电或静电枪释放的电荷可优先被第一导电尖端125吸引，并通过第一导电尖端结构120进行释放。由此，本实施例提供的背光模组100可提供一种新型的抗静电背光模组。另外，当本实施例提供的背光模组100的模组边框110内设置有由阵列基板、对置基板以及夹设在阵列基板和对置基板之间的液晶层组成的液晶盒时，背光模组100可避免静电或静电枪释放的电荷进入液晶盒内部的电路，从而达到保护该液晶盒的效果。另外，通过在模组边框110的不同位置设置多个第一导电尖端结构120可增强背光模组100对来自不同位置的静电或静电枪释放的电荷的吸收能力。
例如，在本实施例一示例提供的背光模组中，如图3所示，背光模组100还包括第一导线130，第一导线130设置在模组边框110内部并与第一导电尖端结构120相连。
例如，如图3所示，第一导线130与第一导电尖端结构120的下部相连。
需要说明的是，与第一导电尖端结构120相连的第一导线130可将第一导电尖端125吸引的静电或静电枪释放的电荷进一步进行释放，从而可使得本实施例提供的背光模组具有更强的抗静电能力。
例如，如图3所示，第一导线130为沿着模组边框110环绕一周的闭合导线。当然，第一导线130也可不闭合，本公开在此不作限制。
例如，在本实施例一示例提供的背光模组中，为了快速将静电或静电枪释放的电荷导出，第一导线可接地。例如，可将第一导线与安装该背光模组的设备的地线相连，从而实现第一导线的接地。
例如，在本实施例一示例提供的背光模组中，第一导线可部分暴露于所述模组边框，从而可通过与空气接触来释放静电或静电枪释放的电荷。
例如，在本实施例一示例提供的背光模组中，第一导线可连接电容，从而将第一导电尖端吸引的静电或静电枪释放的电荷存储在电容中，从而进一步提供本实施例提供的背光模组的抗静电能力。
例如，所述电容包括第一电极和第二电极，所述第一导线一端与所述第一电极相连，另一端与所述第二电极相连。可将第一导线的一端与电容的一个电极相连，将第一导线的另一端与电容的另一个电极相连。
需要说明的是，上述的关于第一导线的各种设置可根据背光模组在实际使用环境中面临的静电或静电枪的释放的电荷的量进行配置或组合，从而达到成本和背光模组抗静电能力的最佳化。
例如，在本实施例一示例提供的背光模组中，如图3和图5所示，模组边框110为中间镂空的矩形框，为了更加有效地吸引来自模组边框110拐角的静电或静电枪释放的电荷，第一导电尖端结构120可设置在模组边框110的一拐角处。例如，为了使得包含本实施例提供的背光模组的显示面板可安全通过静电枪对显示面板右上角的抗静电性能检测，第一导电尖端结构120可设置在模组边框110的右上角，可优先吸引静电枪释放的电荷，从而可使得显示面板安全通过静电枪的抗静电性能检测。值得注意的是，模组边框的拐角处相对于其他位置具有更大的空间，更利于设置第一导电尖端结构120。
需要说明的是，在本实施例提供的背光模组中，模组边框还可为其他多边形框，例如，五边形框、六边形框、八边形框等。当然，模组边框还可为圆形框，本公开在此不作限制。
例如，在本实施例一示例提供的背光模组中，如图3和图6所示，第一导电尖端125与模组边框110靠近第一导电尖端125的表面位于同一平面上。
需要说明的是，因为第一导电尖端125与模组边框110靠近第一导电尖端125的表面位于同一平面上，相对于设置在模组边框110的表面之下，第一导电尖端125可更加接近静电的来源或静电枪释放电荷的位置，从而可提高第一导电尖端125吸引电荷的能力，同时也不会对背光模组100的安装和应用造成困扰。当然，第一导电尖端也可不与模组边框靠近第一导电尖端的表面位于同一平面上；本公开在此不作限制。
例如，在本实施例一示例提供的背光模组中，为了更加有效地吸引来自背光模组100出光面150的静电或静电枪释放的电荷，如图3和图6所示，第一导电尖端结构120的第一导电尖端125可朝向出光面150。
需要说明的是，为了更加有效地吸引来自其他方向的静电或静电枪释放的电荷，可根据实际的需要将第一导电尖端结构120的第一导电尖端125针对性地设置为朝向该其他方向。
实施例二
本实施例提供一种背光模组，其与实施例一中的背光模组的不同点在于：如图7所示，背光模组100还包括第二导电尖端结构140，其设置在模组边框110内部靠近第一导电尖端结构120的位置。第二导电尖端结构140包括第二导电尖端145，第二导电尖端145处于裸露于模组边框110的裸露状态。需要说明的是，上述的模组边框110内部是指模组边框110的框体内部而并非模组边框110用于放置液晶盒的内侧；上述的裸露于模组边框110的裸露状态是指第二导电尖端145没有被模组边框110的材料所覆盖，例如与模组边框110的表面平齐、或者位于表面之下但通过位于模组边框内的孔洞露出、或者伸出模组边框的表面。
需要说明的是，由于第二导电尖端结构140同样具有可以吸引静电或静电枪释放的电荷的第二导电尖端145，因此，第二导电尖端结构140可进一步提高背光模组的抗静电能力。
例如，在本实施例一示例提供的背光模组中，如图7和图8所示，第二导电尖端结构140的第二导电尖端145朝向模组边框110的内侧。需要说明的是，上述的模组边框的内侧是指模组边框中用于放置液晶盒的位置。
值得注意的是，当本实施例提供的背光模组和包含图1a所示的阵列基板的液晶盒配合形成显示面板时，可将第二导电尖端结构设置在测试线拐角部分的断口附近并将第二导电尖端设置为朝向测试线拐角部分的断口。由此，即使仍有部分静电或静电枪释放的电荷进入测试线拐角部分，但是第二导电尖端可吸引进入测试线拐角部分的静电或静电枪释放的电荷并通过第二导电尖端装置进行释放，从而对包含图1a所示的阵列基板的液晶盒进行二次保护。
例如，在本实施例一示例提供的背光模组中，如图8所示，第二导电尖端145与模组边框110靠近第二导电尖端145的表面(例如，模组边框110的内侧面)位于同一平面上。
需要说明的是，因为第二导电尖端145与模组边框110靠近第二导电尖端145的表面位于同一平面上，相对于设置在模组边框110的表面之下，第二导电尖端145可更加接近静电的来源或静电枪释放电荷的位置，从而可提高第二 导电尖端145吸引电荷的能力，同时也不会对背光模组100的安装和应用造成困扰。当然，第二导电尖端也可不与模组边框靠近第二导电尖端的表面位于同一平面上；本公开在此不作限制。
例如，在本实施例一示例提供的背光模组还可包括第二导线，第二导电尖端结构可与该第二导线相连。
例如，如图9所示，第二导线160与第一导线130可属于同一根导线。当然，第一导线和第二导线也可为不同的导线，本公开在此不作限制。
需要说明的是，与第二导电尖端结构140相连的第二导线160可将第二导电尖端145吸引的静电或静电枪释放的电荷进一步进行释放，从而可使得本实施例提供的背光模组具有更强的抗静电能力。值得注意的是，第二导线同样可以采用实施例一中关于第一导线的各种设置并且可根据背光模组在实际使用环境中面临的静电或静电枪的释放的电荷的量进行配置或组合，从而达到成本和背光模组抗静电能力的最佳化。
实施例三
本实施例提供一种显示面板，其包括上述实施例一中任一的背光模组。
在本实施例提供的显示面板中，由于显示面板具有上述任一所述的背光模组，因此，该显示面板具有对应的背光模组的技术效果。
例如，在本实施例一示例提供的显示面板，如图10所示，显示面板包括背光模组100，其包括模组边框110、设置在模组边框110的内侧的阵列基板210、以及与阵列基板210相连的柔性印刷电路板230。阵列基板210包括导电线路215，导电线路215在阵列基板的边缘具有断口2150。第一导电尖端结构120设置在模组边框110内部靠近导电线路215的断口2150的位置。
例如，如图10所示，导电线路215在阵列基板210的右上边缘具有断口2150；第一导电尖端结构120设置在模组边框110右上的拐角的位置。
在本实施例提供的显示面板中，由于显示面板包括设置在模组边框110内部靠近导电线路215的断口2150的位置的第一导电尖端结构120，依据尖端放电的原理，静电或静电枪释放的电荷可优先被第一导电尖端结构120的第一导电尖端125吸引，并通过第一导电尖端结构120进行释放。由此，本实施例提供的显示面板可避免静电或静电枪释放的电荷进入显示面板内部的电路，从而达到保护该显示面板的效果。
例如，在本实施例一示例提供的显示面板中，如图11所示，显示面板还 包括第二导电尖端结构140，其设置在模组边框110内部靠近第一导电尖端结构120的位置，第二导电尖端结构140包括第二导电尖端145，第二导电尖端145处于裸露于模组边框110的裸露状态。
需要说明的是，由于第二导电尖端结构140同样具有可以吸引电荷的第二导电尖端145，因此，第二导电尖端结构140可进一步提高显示面板的抗静电能力。同样地，显示面板还可包括设置在模组边框内部的第二导线，第二导电尖端结构可与该第二导线相连。并且，第二导线与第一导线可属于同一根导线。当然，第一导线和第二导线也可为不同的导线，本公开在此不作限制。
例如，在本实施例一示例提供的显示面板中，如图11所示，第二导电尖端145朝向导电线路215的断口2150。
在本实施例提供的显示面板中，即使仍有部分电荷进入导电线路215，但是第二导电尖端145可吸引进入导电线路215的静电或静电枪释放的电荷并通过第二导电尖端装置140进行释放，从而对该显示面板进行二次保护。
例如，在本实施例一示例提供的显示面板中，如图11所示，第二导电尖端145与模组边框110靠近第二导电尖端145的表面位于同一平面上。
需要说明的是，因为第二导电尖端145与模组边框110靠近第二导电尖端145的表面位于同一平面上，相对于设置在模组边框110的表面之下，第二导电尖端145可更加接近静电的来源或静电枪释放电荷的位置，从而可提高第二导电尖端145吸引电荷的能力。当然，第二导电尖端也可不与模组边框靠近第二导电尖端的表面位于同一平面上；本公开在此不作限制。
例如，在本实施例一示例提供的显示面板中，如图11所示，导电线路可包括切割后的测试线215。例如，测试线215与阵列基板210上的阵列元件或其他部件电连接，在阵列元件制备完成之后，可以通过测试线215对其性能进行检测。
例如，在本实施例一示例提供的显示面板中，如图12所述，显示面板可包括图1a所示的阵列基板210，第二导电尖端145设置为朝向测试线拐角部分216的断口2160。由此，即使仍有部分静电或静电枪释放的电荷进入测试线拐角部分216，但是第二导电尖端145可吸引进入测试线拐角部分216的静电或静电枪释放的电荷并通过第二导电尖端装置140进行释放，从而对包含图1a所示的阵列基板210的显示面板进行二次保护。
实施例四
本实施例提供一种显示装置，其包括实施例三中任一的显示面板。
在本实施例提供的显示装置中，由于该显示装置具有可抗静电的显示面板，可避免静电或静电枪释放的电荷进入显示面板内部的电路，防止静电释放(Electro-Static Discharge，ESD)发生，从而可保护显示面板内部的电路，进而减少显示异常。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
本申请要求于2016年04月13日递交的中国专利申请第201620307448.2号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
