Description

一种显示面板和显示装置 【技术领域】
本申请涉及一种显示屏技术领域，特别是涉及一种显示面板和显示装置。
【背景技术】
液晶显示器(Liquid Crystal Display，LCD)由于具有低的功耗、优异的画面品质以及较高的生产良率等性能，目前已经逐渐占据了显示领域的主导地位。同样，液晶显示器包含液晶面板和背光模组，液晶面板包括彩膜基板(Color Filter Substrate，CF Substrate，也称彩色滤光片基板)、薄膜晶体管阵列基板(Thin Film Transistor Substrate，TFT Substrate)，上述基板的相对内侧存在透明电极。两片基板之间夹一层液晶分子(Liquid Crystal，LC)。
而液晶显示器为了凸显出现实画面的一体感，无边框涉及应运而生，而当边框取消之后，边缘的测漏光问题就必须被克服，否则会出现外围漏光的现象，对于侧漏光问题，曾有人尝试使用黑色胶布来粘贴以防止漏光问题，但是黑色胶布长期使用后会出现脱落等问题，带来了许多问题。
【发明内容】
有鉴于现有技术的上述缺陷，本申请所要解决的技术问题是提供一种能够提高良率及防止漏光的显示面板和显示装置。
为实现上述目的，本申请提供了一种显示面板，包括：
一种显示面板，其特征在于，包括：
第一基板，包括主动开关阵列及周围金属电路，所述周围金属电路是设置於所述主动开关阵列的周围；
第二基板，相对於所述第一基板设置；
液晶层，形成于所述第一基板及第二基板之间；
前偏光板，设置在所述第一基板外侧；
后偏光板，设置在所述彩膜基板外侧；
密封层，形成于所述显示面板的周围，用于密封所述液晶层于所述第一基板和第二基板之间；以及
遮光防护胶水层，形成于所述密封层上，其中所述遮光防护胶水层是由所述后偏光板的边缘延伸至所述前偏光板的外侧，并遮蔽住所述周围金属电路。
在一些实施例中，所述密封层包括遮光层，所述遮光层采用遮光墨水。
在一些实施例中，所述密封层包括密封胶水层，所述密封胶水层包括热融胶水。
在一些实施例中，所述密封层包括密封胶水层，所述密封胶水层包括光固化胶水。
在一些实施例中，所述遮光防护胶水层包括电磁波防护胶水层、水汽防护胶水层或电磁水汽防护胶水层。
在一些实施例中，所述遮光层采用遮光墨水；所述密封胶水层包括热融胶水或光固化胶水。
在一些实施例中，所述遮光层采用黑色框胶或黑色胶布，所述密封胶水层采用热融胶水或固化胶水。
本申请还提供一种显示装置，包括如上述的显示面板。
本申请还提供一种显示面板，包括：
第一基板，包括主动开关阵列及周围金属电路，所述周围金属电路是设置於所述主动开关阵列的周围；
第二基板，相对於所述第一基板设置；
液晶层，形成于所述第一基板及第二基板之间；
前偏光板，设置在所述第一基板外侧；
后偏光板，设置在所述彩膜基板外侧；
密封层，形成于所述显示面板的周围，用于密封所述液晶层于所述第一基板和第二基板之间；以及
遮光防护胶水层，形成于所述密封层上，其中所述遮光防护胶水层是由所述后偏光板的边缘延伸至所述前偏光板的外侧，并遮蔽住所述周围金属电路。
其中，所述密封层包括遮光层及密封胶水层，所述遮光层采用遮光墨水，所述密封胶水层包括热融胶水；
其中，所述遮光防护胶水层包括电磁波防护胶水层、水汽防护胶水层或电磁水汽防护胶水层。
进一步的，所述遮光层采用遮光墨水。该遮光墨水可以为黑色遮光墨水，遮光配合光线吸收效果达到更好地阻绝光线透出的目的；而且，本方案中，对于材质的物性要求不高，不仅不需要其具备足够的粘性，而且对于遮光率方面，只要遮光墨水的遮光率在90％左右即可。
进一步的，所述密封胶水层包括热融胶水。该热融胶水即聚氨酯湿气反应热熔胶水(PUR胶水)，其作用机理是聚氨酯预聚体与空气中的水份反应,固化交联而形成稳定的化学结构；PUR热熔胶具有耐候性好：由于架桥后具备了不可逆的特性，因而不会受环境温度变化而产生蠕变和发脆；而且，韧性高，初粘力强,具有极强的渗透性和亲和力，粘合强度比同样条件下的其它胶粘剂高出40％～60％，降低了胶粘剂的使用量；保证了本申请产品的良率，避免脱落等问题的发生。
进一步的，所述密封胶水层包括光固化胶水。该光固化胶水，即紫外光固化胶水(UV胶水)，是一种必须通过紫外线光照射才能固化的一类胶粘剂，其固化原理是UV固化材料中的光引发剂(或光敏剂)在紫外线的照射下吸收紫外光后产生活性自由基或阳离子，引发单体聚合、交联化学反应，使粘合剂在数秒钟内由液态转化为固态，极大地提高了工作效率；而且，固化后完全透明、产品长期不变黄、不白化；对比传统的瞬干胶粘接、具有耐环测、不白化、柔韧性好等优点；其粘性和耐用性远远高过黑色胶布等密封材料，避免了脱落的问题，大大提高了产品的良率。
进一步的，所述第一基板包括阵列基板；所述第二基板包括彩膜基板；
所述显示面板还包括：设置在所述阵列基板外侧的前偏光板，以及设置在所述彩膜基板外侧的后偏光板；
所述密封层包括设置在内侧的遮光层，在中间的密封胶水层，以及在所述密封胶水层外侧，从所述前偏光板和后偏光板边缘进行密封的防护胶水层。本方案中由于在密封层的外围设置了一层防护胶水层，提高了基板防尘、防水、防电磁波、防冲击等的能力；而且，由于该防护胶水层是从前偏光板和后偏光板边缘进行密封的，故而，也对前偏光板和后偏光板起到了防冲击等防护作用，且能够防止偏光板翘起不良的问题，提高产品的良率；而且遮光层、密封胶水层和防护胶水层配合的三层结构，起到比单层的复合式胶水封号的遮光性、密封性和缓冲性的效果；而且，对于单层的无形材质要求降低，在提高产品良率的同时，降低了技术的要求
进一步的，所述第一基板包括阵列基板；所述第二基板包括彩膜基板；
所述显示面板还包括：设置在所述阵列基板外侧的前偏光板，以及设置在所述彩膜基板外侧的后偏光板；
所述密封层包括设置在内侧的密封胶水层，在中间的遮光层，以及在所述遮光层外侧，从所述前偏光板和后偏光板边缘进行密封的防护胶水层。本方案中由于在密封层的外围设置了一层防护胶水层，提高了基板防尘、防水、防电磁波、防冲击等的能力；而且，由于该防护胶水层是从前偏光板和后偏光板边缘进行密封的，故而，也对前偏光板和后偏光板起到了防冲击等防护作用，且能够防止偏光板翘起不良的问题，提高产品的良率；而且遮光层、密封胶水层和防护胶水层配合的三层结构，起到比单层的复合式胶水封号的遮光性、密封性和缓冲性的效果；而且，对于单层的无形材质要求降低，在提高产品良率的同时，降低了技术的要求。
进一步的，所述防护胶水层包括电磁波防护胶水层、水汽防护胶水层或电磁水汽防护胶水层。本方案可以根据产品的定位不同，要求不同而选择电磁波防护胶水层、水汽防护胶水层或电磁水汽防护胶水层，从而起到水汽防护或静 电防护等效果，提高产品的品质和质量。
进一步的，所述遮光层采用遮光墨水；所述密封胶水层包括热融胶水或光固化胶水；
所述第一基板包括阵列基板；所述第二基板包括彩膜基板；
所述显示面板还包括：设置在所述阵列基板外侧的前偏光板，以及设置在所述彩膜基板外侧的后偏光板；
所述密封层包括设置在内侧的遮光层，在中间的密封胶水层，以及在所述密封胶水层外侧，从所述前偏光板和后偏光板边缘进行密封的防护胶水层；
所述防护胶水层包括电磁波防护胶水、水汽防护胶水或电磁水汽防护胶水。遮光层、密封胶水层和防护胶水层配合的三层结构，起到比单层的复合式胶水封号的遮光性、密封性和缓冲性的效果；而且，对于单层的无形材质要求降低，在提高产品良率的同时，降低了技术的要求。

所述防护胶水层包括电磁波防护胶水、水汽防护胶水或电磁水汽防护胶水。本方案中，保留了黑色胶布或者黑色框胶，因而可以保留原有的相关器械，防止浪费，而在黑色胶布或者黑色框胶的外侧设置密封胶水层和防护胶水层，则可以提高本方案产品的遮光性、粘性、耐用性、防冲击性、防水汽、防静电等效果，而且，对于黑色胶布或者黑色框胶的物性要求也相对降低，即原来不合格的黑色胶布或者黑色框胶，已然能够进行部分利用，减少浪费，提高了产品的良率。
一种显示装置，包括如本申请任一公开的显示面板。
本申请的有益效果是：无边框的显示面板，如无边框液晶面板主要包括基板和背光模组两部分，其中基板主要包括阵列基板、彩膜基板以及从两端对阵列基板和彩膜基板进行密封的密封层，现有的密封层常常使用黑色胶布进行密封，但黑色胶布在长期使用后，很容易出现粘性减弱而出现脱落的情况，这将造成漏光，以及产品良率不高的问题；而本申请中，由于采用了遮光层和密封胶水层两层，而因为每层的目的明确，无需像黑色胶布一般既要考虑遮光率又要考虑密封性，因而可以做到专一，进而达到更好地遮光性和密封性，避免出现脱落和漏光的问题，提高产品的良率。

【具体实施方式】
为了使本技术领域的人员更好地理解本申请中的技术方案，下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都应当属于本申请保护的范围。
无边框产品：薄膜晶体管层液晶显示器(Thin Film Transistor-Liquid Crystal Display，TFT-LCD)为了凸显出现实画面的一体感，无边框涉及应运而生，而当边框取消之后，边缘的测漏光问题就必须被克服，否则会出现外围漏光的现象，对于侧漏光问题，曾有人尝试使用黑色胶布来粘贴以防止漏光问题，但是黑色胶布长期使用后会出现脱落等问题，带来了许多问题。
图1是采用黑色胶框作为密封层的显示面板的示意图，如图1所示，为了解决黑色胶布脱落的问题，发明人曾使用了以黑色框胶50代替黑色胶布的方案，即在阵列基板30和彩膜基板40的两端涂布黑色框胶50，用于将光线吸收而阻绝光线的透出，这一方式很大程度上达到了原有黑色胶布的遮蔽效果，同时，减少长期使用后脱落的问题发生。
但是这一方式需要增加材料和制程工艺，不仅麻烦而且成本较高；而且，由于黑色框胶的物性要求较高，不仅要求具备遮光性，而且需要足够的粘性、防水性甚至是防冲击性等，这进一步增加了该方式的推广难度。
而为了解决这些问题，发明人进一步的改进得到如下的方案：
图2是本申请一种显示面板的示意图，参见图1所示的实施例，该显示面板100，包括：
第一基板(例如阵列基板30)；
第二基板(例如彩膜基板40)；相对於第一基板设置；
密封层60，设置在所述显示面板100的两端，用于密封所述第一基板和第二基板；
所述密封层60包括：
遮光层61和密封胶水层62。
其中，附图所示的遮光层61和密封胶水层62位置可以互换。
在一些实施例中，TFT阵列及彩膜也可形成於单一基板上。
在一些实施例中，显示面板100可例如是液晶显示面板、OLED显示面板、曲面显示面板或其他显示面板。
