Description

显示面板、显示装置及其制作方法和模具 技术领域
本发明的实施例涉及一种显示面板、显示装置及其制作方法和模具。
背景技术
目前，随着显示技术的发展，窄边框技术成为市场的一个卖点。但是就TFT-LCD和OLED显示器而言，单纯的无边框从机理上很难通过。进一步地，从技术方案来说，现在的窄边框越来越趋向于通过压缩外围电路和封框胶的空间来实现窄边框，这种窄边框的带来的风险包括：电路越来越靠外，外围电路无法保护，容易带来静电释放的风险；边框越来越窄，基板与基板之间容易由于封框胶的粘结力不足导致分离；以及模组组装过程中容易破损产生微裂纹等。
发明内容

附图说明
以下将结合附图对本发明的实施例进行更详细的说明，以使本领域普通技术人员更加清楚地理解本发明，其中：
图1为本发明实施例提供的一种显示面板的结构示意图；
图2本发明实施例提供的一种包含引线区的显示面板的结构示意图；

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动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。
除非另作定义，此处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。本公开专利申请说明书以及权利要求书中使用的“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。“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相应地改变。
如图1所示为本发明实施例提供的一种显示面板的结构示意图，包括：相对设置的第一基板101和第二基板102；设置在第一基板101和第二基板102之间的非显示区域中的封框胶103；以及设置在显示面板侧面的保护结构104，其中，保护结构104的材料为具有粘性的绝缘材料，保护结构在垂直于第一基板101和第二基板102表面方向上的高度不大于显示面板的厚度。
已知技术的窄边框显示器中，电路靠外，使得外围电路无法得到保护，存在静电释放的风险；而本发明实施例提供的显示面板在侧面增加了保护结构104，而且保护结构104为绝缘材料，因此可以避免外围电路的静电释放；同时，已知技术中玻璃基板外围无保护层，在模组组装过程中容易破损、产生微裂纹，而本发明实施例提供的保护结构104可以起到一定缓冲作用，降 低显示面板破损产生微裂纹的风险。
在一个示例中，如图1所示，保护结构104以从第一基板101远离第二基板102的表面延伸至第二基板102远离第一基板101的表面的方式设置在第一基板和第二基板的同一侧。
在一个示例中，为了使保护结构104能够固定在显示面板的侧面，保护结构104的材料可具有粘性。已知技术中窄边框显示器的边框很窄，基板与基板之间容易由于封框胶103的粘结力不足而分离，选取具有粘性的材料作为保护结构104，可以对第一基板101和第二基板102起到粘结作用，使第一基板101和第二基板102不易分离。
在一个示例中，为了不影响显示面板的厚度，保护结构104在与第一基板101和第二基板102表面垂直的方向上的高度不大于显示面板的厚度，也就是说，假设图1中第一基板101的上表面到第二基板102的下表面之间的距离为a(即：保护结构104在与第一基板101和第二基板102垂直方向上的高度)，则a的数值小于或者等于显示面板的厚度。
已知的封框胶103的周边、尤其是拐角处都会有一定的电路裸漏，环境中的酸或水分对于周边电路可能造成一定的腐蚀。在一个示例中，为了保护外围电路不被腐蚀，保护结构104的吸水率小于预设阈值，而预设阈值为能够影响显示面板正常工作的最低吸水率值。这可以通过使选取的保护结构104的材料的吸水率小于预设阈值(该预设阈值为能够影响显示面板正常工作的最低吸水率值)。因此，可以选取吸水率较低的材料形成保护结构104，以防止外围线路受到环境中的酸或水分等腐蚀。
在一个示例中，可在显示面板的侧面设置引线区105，图2为本发明实施例提供的一种包含引线区的显示面板的结构示意图；如图2所示，可在显示面板的第二基板102突出于第一基板101的一侧设置引线区105，未非设置引线区105的一侧设置保护结构104。也就是说，在如图2中所示的第一基板101和第二基板102对齐的一侧(即，图2中的右侧)设置保护结构104，而第一基板101和第二基板102没有对齐的一侧(即，图2中的左侧)不设置保护结构104而是设置引线，以防影响显示面板的正常工作。
由于本发明的实施例适用于窄边框的设计，为了尽量不增加边框的宽度，保护结构104的厚度要尽量小。在一个示例中，保护结构104在垂直于第一基板101和第二基板102侧面的方向上的宽度为0.001μm-2mm。也就 是说，图2中所示保护结构104与第一基板101和第二基板102的侧面相垂直的方向上的截面宽度为b，其中b的数值为0.001μm-2mm。
在一个示例中，如图2所示，保护结构104的外表面为弧形面。然而，本发明实施例不对保护结构104的形状进行任何具体限制，只要是能够起到保护作用就可以。例如，保护结构104在与第一基板101和第二基板102的侧面相垂直的方向上的截面形状可以为封闭U型、正方形、长方形、梯形、锯齿形或阶梯形。一般来说，保护结构104的具体的形状由用于制作保护结构的模具的内表面的形状决定，模具的内表面的形状不同，则保护结构的外表面或者截面的形状也不相同，但只要是能够起到保护作用且利用脱模形成的形状均可以使用。
本发明实施例提供的保护结构104的材料可以是满足具有粘性且吸水率较低的任意绝缘材料。例如，保护结构104的材料为封框胶材料。而具体的封框胶的材料可以为现有技术中已知的任意制作封框胶的材料。
如上所述，本发明实施例提供的显示面板在侧面增加了保护结构，一方面，由于保护结构具有绝缘特性，可以避免外围电路的静电释放；另一方面，由于保护结构具有粘性，可以对第一基板和第二基板起到一定的粘附作用；此外，在模组组装过程中，保护结构可以起到一定缓冲作用，降低显示面板破损产生微裂纹的风险。
基于同一发明构思，本发明实施例还提供了一种显示装置，该显示装置包括本发明实施例提供的上述显示面板。由于该显示装置解决问题的原理与上述显示面板相似，因此该显示装置的实施可以参见上述显示面板的实施，重复之处不再赘述。
本发明实施例还提供一种制作如本发明实施例提供的上述显示面板的方法。图3为所述方法的一个示例的流程图，包括下列步骤：
步骤301，将待制作保护结构的显示面板固定在厚度不大于显示面板厚度的模具中，显示面板的侧面与模具的内表面形成注塑型腔；
步骤302，向注塑型腔内注入胶料；
步骤303，待胶料成型后，剥离模具。
本发明实施例采用注塑的方式制作上述显示面板侧面的保护结构。注塑开始前，先将待制作保护结构的显示面板和模具进行固定，具体的固定方式不做限定，例如，可以采用真空吸附的方法对显示面板和模具进行固定；再 将模具和显示面板进行机械对位，其中模具的厚度不大于待制作保护结构的显示面板的厚度，且使显示面板的侧面与模具的内表面形成注塑型腔；在预设压力下，向注塑型腔内喷涂胶料，直到排气口中有连续的胶流出时停止喷胶，其中预设压力为根据模具的大小确定的喷胶压力(如1MPa)；在温度为50-150℃下，将胶料加热固化2-20min，直到型腔内的胶料全部固化成型后，在高于室温的温度(该温度可以根据情况进行调整)下进行脱模，剥离模具。
为了更清楚地示意本发明的模具，图4为本发明实施例提供的一种通过注塑方式制作保护结构的俯视图；图4中包括待制作保护结构的显示面板401、模具402、排气口403或404和注胶口404或403。一般将注胶口设置在404或者403的位置处，若注胶口位于404的位置处，则排气口位于403所在的位置处，反之亦然；其中，排气口可以是牛角管或者类似的能够方便模具402内的气体排出的装置。其中，图4只是一种待制作保护结构的显示面板401和模具402位置关系的示意图，至于模具的具体形状，可以根据要制作的保护结构的形状进行调整，在此并不做限定。
在一个示例中，若显示面板包括引线区，则在注塑之前需要对引线区进行填充。例如，在向注塑型腔内注入胶料之前，还可以采用填充材料填充显示面板的引线区一侧的阶梯状部分，以使显示面板的引线区被填充满而不至于有胶料流到引线区。例如，填充材料可为聚四氟乙烯，或者是其它的不会与胶料发生反应、且不会影响显示面板上引线的材料。
在一个示例中，为了方便脱模，可以在注塑之前在模具表面涂覆一层脱模剂。例如，在将待制作保护结构的显示面板固定在厚度不大于显示面板厚度的模具中之前，还可以在模具的型腔内表面上涂覆能够对胶料进行脱模的脱模剂。脱模剂的材料在此不做限定，可以根据用于制作保护结构的材料选取脱模剂的材料。例如，脱模剂可为硅胶脱模剂。
在一个示例中，在进行注塑之前，需要固定模具并对模具和显示面板接触的缝隙处进行密封；也可以根据需要将显示面板和模具全部或者部分进行封堵；只要能够防止喷胶过程中或者喷胶结束后由于气体泄漏而造成的胶料溢出即可。例如，在向注塑型腔内注入胶料之前，还可采用密封薄膜来密封模具与显示面板的接缝处。例如，密封薄膜的材料可为橡胶材料或者聚氨酯材料。
在一个示例中，在取出制作完成的显示面板之后，还可对形成的保护结 构的表面进行处理。例如，剥离模具之后，还可使用刀具将成型后显示面板周边多余的胶料去除；将封边的封框胶进行简单的外观整形，使得胶的形状更加圆滑，规整。
为了更清楚地说明本发明实施例提供的制作上述显示面板的方法，如图5所示，一个示例性方法的整体流程可包括下列步骤：
步骤501，在模具的型腔内表面上涂覆能够对胶料进行脱模的脱模剂；
步骤502，将待制作保护结构的显示面板固定在厚度不大于显示面板厚度的模具中；
步骤503，采用填充材料对显示面板的引线区一侧的阶梯状部分进行填充；
步骤504，采用密封薄膜密封模具与显示面板的接缝处；
步骤505，向注塑型腔内注入胶料；
步骤506，待胶料成型后，剥离模具；
步骤507，使用刀具将成型后显示面板周边多余的胶料去除。
基于同一发明构思，本发明实施例还提供了一种模具，该模具应用于本发明实施例提供的上述制作方法。
如图4所示，应用于本发明实施例提供的上述制作方法的模具402为非闭合的中空结构，在模具402的内侧设置有开口402’。即，模具是能够围在显示面板侧面的类似于凹槽型的中空结构，模具的开口与显示面板的待设置保护结构的侧面相接触以形成注塑的型腔。
在一个示例中，为了保证制作的保护结构的高度不超过显示面板的厚度，模具开口402’的深度不大于待制作保护结构的显示面板的厚度。
在一个示例中，如图4所示，模具在平行于显示面板方向所取的截面为直角U型，即，从显示面板的上方俯视时，模具402的形状为直角U型。而模具内表面的形状，则可以根据需要制作的保护结构的形状进行设计，即，模具的内表面的形状与制作的保护结构的外表面形状相同。例如，模具的内表面可为弧形面。针对不同形状的保护结构，模具的内表面还可以为U型面、直角U型面、梯形面或锯齿形面等。
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。
本申请要求于2016年2月24日提交的名称为“一种显示面板、显示装置及其制作方法及模具”的中国专利申请No.201610102414.4的优先权，该申请全文以引用方式合并于本文。
