Description

显示面板及其制造方法、显示装置 技术领域
本发明涉及液晶显示技术领域，尤其涉及一种显示面板及其制造方法、显示装置。
背景技术
随着LCD(Liquid Crystal Display)面板的迅速发展，LCD显示器以其超薄、重量轻、无辐射、性能稳定等诸多优势逐渐成为显示技术的主流。
无边框显示器并不一定是真正的没有边框，显示器的液晶面板中，通常包括彩膜(CF)基板和阵列(TFT Array，即薄膜晶体管阵列)基板，二者之间填充有液晶，在传统的无边框显示器的整机设计中，通常是彩膜基板侧朝外、阵列基板侧朝向背光源，即最终的用户观看时肉眼看到的是液晶面板的彩膜基板。
液晶面板放置在背板上，由于阵列基板的Bonding(绑定)区的存在，液晶面板的阵列基板尺寸会大于彩膜基板尺寸，阵列基板的Bonding区朝侧面伸出，需要设计边框以对暴露的Bonding区进行遮挡而避免影响视觉效果，因此，传统的液晶面板需要借助复杂的光学组件遮挡在非显示区域的边框上方，很难做到真正的无边框设计。
发明内容
鉴于现有技术存在的不足，本发明提供了一种显示面板及其制造方法、显示装置，可以实现超窄边框设计，甚至做到无边框。
为了实现上述的目的，本发明采用了如下的技术方案：
一种显示面板，包括第一基板、第二基板、覆晶薄膜以及遮光阵列层，所述第一基板与所述第二基板相对且间隔设置，且所述第一基板一端超出所述第二基板形成绑定端，所述覆晶薄膜绑定在所述绑定端朝向所述第二基板的面上且所述第一基板相对于所述第二基板更靠近出光面；所述第一基板内表面设有位于非像素区的金属信号线，所述遮光阵列层位于非像素区且完全遮挡所述金 属信号线。
作为其中一种实施方式，所述第二基板内表面形成有位于像素区的色阻和位于非像素区的黑色矩阵，所述遮光阵列层、所述黑色矩阵在所述第二基板上的组合投影位于非像素区且完全覆盖非像素区。
作为其中一种实施方式，所述黑色矩阵填充于每两个相邻的所述色阻之间的间隔内。
作为其中一种实施方式，所述黑色矩阵与所述遮光阵列层在所述第一基板上的投影至少部分重叠。
作为其中一种实施方式，所述黑色矩阵被所述遮光阵列层遮挡的部位的厚度小于所述黑色矩阵的其他部位的厚度。
作为其中一种实施方式，所述黑色矩阵的厚度小于所述色阻的厚度。
作为其中一种实施方式，所述遮光阵列层的镂空区域填充有透明材料。
作为其中一种实施方式，所述遮光阵列层为光阻。
本发明的另一目的在于提供一种所述的显示面板的制造方法，包括：
提供一液晶盒，所述液晶盒包括第一基板、第二基板以及二者之间的液晶；
在所述第一基板背离所述第二基板的表面制作一层遮光膜层；
透过掩膜版对所述遮光膜层曝光；
蚀刻掉所述遮光膜层被曝光后的部分，在所述第一基板表面形成正对所述金属信号线的图案化的遮光阵列层；
分别在所述遮光膜层和所述第二基板的外表面贴附上偏光片、下偏光片。
本发明的又一目的在于提供一种显示装置，包括背光模组和所述的显示面板，所述背光模组设于所述第二基板所在侧。
本发明的第一基板朝向观看者，覆晶薄膜绑定在第一基板的绑定端内侧，实现了无边框设计，通过在第一基板的外表面设置有图案化的遮光阵列层，该遮光阵列层形成与第一基板内表面的金属信号线对应的图案，以实现对金属信号线的遮盖，当外界环境光入射至显示面板，会在遮光阵列层中被减弱或阻隔，使其能到达金属信号线的光强度大大减弱，从而降低了金属信号线的反光程度。
附图说明
图1为本发明实施例的显示装置的结构示意图；
图2为本发明实施例的显示面板的结构示意图；
图3为本发明实施例的显示面板的制造方法流程图；
图4为本发明实施例的显示面板的制造工艺过程图。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
参阅图1和图2，本发明实施例的显示装置包括背光模组70和设于背光模组70上方的显示面板，显示面板包括第一基板10、第二基板20、覆晶薄膜30以及遮光阵列层40，第一基板10与第二基板20相对且间隔设置，且第一基板10一端超出第二基板20形成绑定端，覆晶薄膜30绑定在绑定端朝向第二基板20的面上且第一基板10相对于第二基板20更靠近出光面，即朝向观看者，背光模组70设于第二基板20所在侧；第一基板10内表面设有位于非像素区的金属信号线100，遮光阵列层40位于非像素区且完全遮挡金属信号线100。
这里，第一基板10为TFT基板，第二基板20为彩膜基板，金属信号线100在第二基板20上的投影位于相邻的色阻单元200之间的间隔内。第二基板20的内表面形成有位于像素区的色阻200和位于非像素区的黑色矩阵201，遮光阵列层40、黑色矩阵201在第二基板20上的组合投影位于非像素区且完全覆盖非像素区。遮光阵列层40、黑色矩阵201在第二基板20上的组合投影即二者在第二基板20上的投影所覆盖的组合区域。
一般地，黑色矩阵201填充于每两个相邻的色阻200之间的间隔内。然而，本实施例的黑色矩阵201也可以设计成与遮光阵列层40在第一基板10上的投影互不重叠，即黑色矩阵201上被遮光阵列层40遮挡的部分可以省去，或者，黑色矩阵201被遮光阵列层40遮挡的部位的厚度小于黑色矩阵201的其他部位的厚度。由于金属信号线100和遮光阵列层40均可以作为遮挡像素间串光的作用，因此，黑色矩阵201的厚度可以制作成小于色阻200的厚度，甚至完全省去。
另外，显示面板还具有分别贴合在遮光膜层1和第二基板20的外表面的上偏光片50、下偏光片60，遮光阵列层40的镂空区域还可以填充有透明材料，使得遮光阵列层40与透明材料形成平整的表面，以供上偏光片50更好地贴附。该遮光阵列层40为透明的光学胶或平坦层。覆晶薄膜30通过异方性导电胶B粘合在金属信号线100上，其另一端绑定到PCB(印刷电路板)31上，作为其中一种实施方式，遮光阵列层40为光阻。
如图3和图4，为本发明的一种显示面板的制造方法，包括：
S01、提供一液晶盒，液晶盒包括第一基板10、第二基板20以及二者之间的液晶；
S02、在第一基板10背离第二基板20的表面制作一层遮光膜层1，例如，该遮光膜层1的制作方式可以采用蒸镀的方式；
S03、透过具有预定镂空图案的掩膜版M对遮光膜层1曝光；
S04、蚀刻掉遮光膜层1被曝光后的部分，留下未被光照的部分，在第一基板10表面形成正对金属信号线100的图案化的遮光阵列层40；
S05、分别在遮光膜层1和第二基板20的外表面贴附上偏光片50、下偏光片60。
其中，第一基板10为TFT基板，第二基板20为彩膜基板，金属信号线100在第二基板20上的投影位于相邻的色阻单元200之间的间隔内。遮光阵列层40、黑色矩阵201在第二基板20上的组合投影位于非像素区且完全覆盖非像素区。黑色矩阵201与遮光阵列层40在第一基板10上的投影至少部分重叠，以防止观看者从显示面板的宽度两侧的方向观看显示画面时，可以看到从黑色矩阵201、遮光阵列层40之间的缝隙处漏出的光线。或者，黑色矩阵201被遮光阵列层40遮挡的部位的厚度小于黑色矩阵201的其他部位的厚度。由于金属信号线100和遮光阵列层40均可以作为遮挡像素间串光的作用，因此，黑色矩阵201的厚度可以制作成小于色阻200的厚度，甚至完全省去。
在遮光阵列层40完成后，还可以在遮光阵列层40的镂空区域填充光学胶或平坦层等透明材料，一方面提高遮光阵列层40的结合强度，另一方面，提供平整的上偏光片50的贴附表面。
综上所述，本发明的第一基板朝向观看者，覆晶薄膜绑定在第一基板的绑定端内侧，实现了无边框设计，通过在第一基板的外表面设置有图案化的遮光 阵列层，该遮光阵列层形成与第一基板内表面的金属信号线对应的图案，以实现对金属信号线的遮盖，当外界环境光入射至显示面板，会在遮光阵列层中被减弱或阻隔，使其能到达金属信号线的光强度大大减弱，从而降低了金属信号线的反光程度。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
