Description

一种显示面板和显示装置 【技术领域】
本发明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】
随着科技的发展和进步，液晶显示器由于具备机身薄、省电和辐射低等热点而成为显示器的主流产品，得到了广泛应用。现有市场上的液晶显示器大部分为背光型液晶显示器，其包括液晶面板及背光模组(backlightmodule)。液晶面板的工作原理是在两片平行的玻璃基板当中放置液晶分子，并在两片玻璃基板上施加驱动电压来控制液晶分子的旋转方向，以将背光模组的光线折射出来产生画面。
其中，薄膜晶体管液晶显示器(Thin Film Transistor-Liquid Crystal Display，TFT-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，薄膜晶体管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，TFTSubstrate)和光罩(Mask)，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(LiquidCrystal，LC)。
而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。
如何更好地解决测漏光问题成为了本领域技术人员亟待解决的问题。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这 些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
【发明内容】
有鉴于现有技术的上述缺陷，本发明所要解决的技术问题是提供可以减少无边框产品侧漏光或侧反射光问题的显示面板和显示装置。
为实现上述目的，本发明提供了一种显示面板，包括：
基板；
设置在所述基板相对背面一侧的背光模组；以及
偏光层，贴覆于所述基板的外侧面，其中所述偏光层包括第一偏光层和外围的第二偏光层；所述第二偏光层的透光率低于所述第一偏光层。
进一步的，所述基板包括显示区域和显示区域外围的引线区域，所述第一偏光层对应所述显示区域贴覆于基板外侧面，所述第二偏光层对应所述引线区域贴覆于基板外侧面。该引线区域即外围金属密集线路区域，该处会出现侧漏光或侧反射光的问题，这一问题会造成产品的良品率不高的问题，本方案中，对应引线区域贴覆第二偏光层，很好的解决了这一问题。
进一步的，所述第一偏光层和第二偏光层一体成型；
所述第二偏光层采用激光或高强度光能进行碳化处理。本方案中，第一偏光层和第二偏光层一体成型，而通过激光或高强度光线将外围对应外围金属密集线路区域进行了碳化处理，碳化处理将使得该处的偏光层变为黑色，这将相当于黑色胶布或黑色胶框，达到了遮蔽的效果，而不用担心黑色胶布带来的可能脱落的问题，也不用担心使用黑色胶框可能带来的额外制程设备和成本的问题。
进一步的，所述第一偏光层采用一般偏光层材料制成；所述第二偏光层采用透光率低或不透光材料制成。偏光层的作用是过滤掉杂光﹐能够过滤99％的眩光﹐增强视觉敏锐力﹐提高颜色对比度和最大的视觉舒适感；本方案中，使 用透光率低或不透光材料制成第二偏光层，不仅能够较好的防止基板内部的光线的侧漏问题，对于外界光线的反射等问题也能够很好的解决。
进一步的，所述第二偏光层采用激光或高强度光能进行碳化处理。第一偏光层和第二偏光层分别进行贴覆，如此，第二偏光层可以单独进行激光或高强度光能的碳化处理，避免一体成型的偏光层可能出现的碳化过界的问题，减少浪费。
进一步的，所述基板包括显示区域和显示区域外围的引线区域；
所述第一偏光层整面贴覆于所述显示区域和引线区域，所述第二偏光层贴覆于引线区域，对应设置在所述第一偏光层的内侧或外侧。本方案中，第一偏光层将整个偏光层区域进行贴覆，配以贴覆在外围的第二偏光层，这样可以避免第一偏光层和第二偏光层之间存在缝隙的问题，而且两层偏光层的叠加，将更好地提高外围处偏光层的遮蔽效果，提高产品良品率。
进一步的，所述第二偏光层的厚度薄于所述第一偏光层；
所述第一偏光层对应引线区域的部位的厚度相对其他部位薄；
所述第一偏光层采用一般偏光层材料制成；所述第二偏光层采用透光率低或不透光材料制成。本方案中，第一偏光层对应引线区域的厚度较薄，配以同样较薄的第二偏光层，可以避免两层偏光层叠加而太厚的问题，在适合情况下，甚至能够使得引线区域处的偏光层厚度与其他部位相当，如此，将不会在形成遮蔽效果的同时，带来不必要的问题。
进一步的，所述第二偏光层，或第二偏光层及第一偏光层对应引线区域的部位采用激光或高强度光能进行碳化处理。本方案中，对第二偏光层或者第二偏光层及第一偏光层对应引线区域的部位采用激光或高强度光能进行碳化处理，可以得到碳化为黑色的偏光层，在保证贴覆效果的同时，进一步提高，该引线区域处的遮蔽效果，而黑色能够具备一定的吸收光线的效果，不仅能够遮蔽和吸收基板内部的背光光线，而且同样对外界光线带来的反射光形成了较好的解决效果。
进一步的，所述基板还包括：
在前的阵列基板，在后的彩膜基板；
以及夹持其中的液晶层；
所述阵列基板和液晶层之间还依次设置有薄膜晶体管层和第一偏光片；
所述彩膜基板和液晶层之间还依次设置有彩色滤光层和第二偏光片；
和用于将所述阵列基板和彩膜基板从两端部进行密封的框胶。胶框的设置，能够使得阵列基板和彩膜基板内部的液晶层的结构很好的进行“密封”，防止灰尘进入，从而达到较好的显示效果；而偏光片的设置则是因为偏光片属於一种只允许特定振动方向的光线才能透过的光片，其主要功能为过滤TFT LCD中背光模组所发出非特定偏振方向的光源，将其转化为偏极光，此偏极化後的光线再透过液晶分子的扭转，即可控制光线通过的多寡，藉以达到控制液晶显示器画面明暗之目的。
本发明还提供了一种显示装置，包括本发明任一公开的显示面板。
本发明的有益效果是：在制作液晶面板时，在阵列基板面向用户的一侧常常会使用到偏光板或偏光膜，即本案所述的偏光层，而无边框产品受到薄膜晶体管层阵列对应的外围金属密集线路区域的影响，会使得无边框产品被人眼观察到反射光，造成产品良品率低的问题；本发明由于在偏光层的外围设置了透光率低于第一偏光层的第二偏光层，减少同样设置在外围的外围金属密集线路区域的影响，减少人眼观察到反射光的概率和强度，提高了产品的良品率；而且，由于同属偏光层，第二偏光层可以使用同样的贴覆制程进行贴覆，如此，便不会出现使用黑色胶布可能带来的脱落的问题，另外，也可以避免发明人之前曾使用黑色胶框而带来了需要额外的制程设备和制程材料成本的问题，在保证防止测漏光和侧反射光的同时，保证成本的低廉；同时，由于第二偏光层的贴覆能够适用原有的贴覆设备，故而能够缩短制程和工艺生产时间。

图1是Frame BM(黑色胶框)制程的示意图，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代替黑色胶布的方案，即在引线区域(外围金属密集线路区域)涂布黑色框胶，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，特别的原有的贴覆机等不能进行直接利用，故而需要增添新的制程设备，不仅麻烦而且成本较高；而且，这一方式，对于黑色框胶的遮光率、粘度和防水性等都有较为严格的要求，这进一步增加了该方式的推广难度。
