Description

显示基板的制备方法、显示面板的制备方法和显示装置 技术领域
本发明涉及显示技术领域，具体地，涉及一种显示基板的制备方法、显示面板的制备方法和显示装置。
背景技术
近年来，随着数字电视的普及，传统CRT显示器由于其数字化困难，以及体积大，重量大，有辐射等缺点，已经出现了被新一代显示技术取代的趋势，其中，液晶显示器由于具有重量轻、体积薄、无辐射、低耗电、显示效果好等优点已经开始大量的普及成为主流产品。液晶面板的制造工艺包括以下几个步骤：阵列基板制备、对盒和模组制备，其中，对盒工艺又包括步骤：印刷液晶取向膜、液晶取向膜摩擦取向、封框胶涂覆、液晶注入、阵列基板和彩膜基板对盒以及封框胶固化等。
图1示出了对显示面板进行封框胶固化的操作的剖视示意图。如图1所示，阵列基板1和彩膜基板2对盒后，位于阵列基板1和彩膜基板2的液晶层3被封框胶5包围。阵列基板1和彩膜基板2与液晶层3接触的一侧涂覆有取向层4。
对封框胶固化时，采用紫外线(图1中向上指示的箭头所示)对完成对盒后的显示面板进行照射。由于封框胶固化所用的掩模板6的设计精度不良和紫外线发散的原因，显示面板的显示区域也接受一定量的紫外线辐射。如图1所示，掩模板6和封框胶5之间的距离为d，紫外光从上述宽度为d的区域照射至显示面板的显示区域周边，从而不可避免的对阵列基板1的显示区域边缘的金属层(例如，像素电极层等)进行照射，使得金属层的电子接收能量而产生迁移。当电子迁移到与显示区域边缘接触的取向层4上时会对位于显示区域的液晶分子的偏转造成影响，从而在显示区域的边缘产生亮度不均等缺陷，严重影响了画面品质。
发明内容
本发明实施例提供一种显示基板的制备方法以降低后续在封框胶 固化时进行的紫外线照射对显示区域的影响。还提供一种显示面板的制备方法和显示装置。
根据本发明的第一方面，提供一种显示基板的制备方法，所述显示基板包括取向层和金属层，所述方法包括：在所述取向层完成取向后对所述显示基板进行第一次紫外线照射，使所述金属层的电子迁移至所述取向层。
优选地，所述紫外线的波长范围为200-400nm。
优选地，所述紫外线的照度大于500勒克司度。
优选地，所述显示基板为阵列基板，所述金属层包括像素电极层。
优选地，所述显示基板为彩膜基板，所述金属层包括公共电极层。
根据本发明的第二方面，提供一种显示面板的制备方法，所述显示面板包括显示基板，所述方法包括：使用如第一方面中所述的显示基板的制备方法制备所述显示基板。
优选地，所述方法还包括：制备对向基板，所述对向基板用于与所述显示基板对盒形成显示面板；在所述显示基板或对向基板上涂覆封框胶；将所述显示基板和对向基板对盒；以及在所述显示基板和对向基板之间设置液晶。
优选地，所述方法还包括：在将所述显示基板和对向基板对盒之后，对所述封框胶进行第二次紫外线照射完成所述封框胶固化，第二次紫外线的波长大于等于第一次紫外线的波长，第二次紫外线的照度小于等于第一次紫外线的照度。
根据本发明的第三方面，提供一种显示装置，包括采用上述的显示面板的制备方法制备的显示面板。
本发明基于以下思想：在显示基板的取向层完成取向后对显示基板进行一次紫外线预照射，使得显示基板的金属层中的电子在紫外线的照射下接收能量而发生迁移，并且均匀分布在显示基板显示区域的取向层上。这样，虽然取向层上分布有电荷，但上述电荷在整个显示区域均匀分布，对显示区域的周边和显示区域的中心的液晶分子的影响一致，不会产生显示区域的边缘亮度不均的缺陷。

具体实施方式
为使本领域技术人员更好地理解本发明的技术方案，下面结合附图和具体实施方式对本发明作进一步详细描述。
实施例1
本文中描述的显示基板通常包括阵列基板和彩膜基板。图2为根据本发明的一个实施例对阵列基板1进行第一次紫外线照射的操作的剖视示意图，并且图3为根据本发明的一个实施例对彩膜基板2进行第一次紫外线照射的操作的剖视示意图。如图2所示，阵列基板1的金属层包括像素电极层7。如图3所示，彩膜基板2的金属层包括公共电极层8。
在制备上述显示基板(阵列基板和/或彩膜基板)时，可以在显示基板的取向层4完成取向后对显示基板进行一次紫外线预照射，使显示基板的金属层中的电子迁移至取向层4。
更具体地，所述紫外线预照射使得显示基板的金属层中的电子能够在紫外线的照射下接收能量而发生迁移，并且均匀分布在显示基板显示区域的取向层4上。这样，虽然取向层4上分布有电荷，但上述的电荷在整个显示区域均匀分布，对显示区域的周边和显示区域的中心的液晶分子的影响一致，不会产生显示区域的边缘亮度不均的缺陷。
在一个示例中，所述紫外线的波长范围为200-400nm。在上述的紫外线波长范围内金属层的电子容易被激发而产生迁移，同时，封框胶5在上述的波长范围内能够固化。
在一个示例中，所述紫外线的照度大于500勒克司度。在这样的照度条件下，金属层的电子接收足够的能量从而产生迁移，这样才能 将在上述紫外线波长下能够被激发的电子全部激发并迁移。
应当理解的是，上述显示面板可以包括其它金属层，上述的像素电极层和公共电极层只是为了举例说明，对于不同的显示面板类型上述的金属层可以不同。
应当理解的是，在对上述显示基板进行第一次紫外线照射(预照射)之前可以进行步骤：制备显示基板上的其它各功能层，并且对完成各功能层制备的显示基板涂覆取向层和摩擦取向层，所有这些步骤均为现有技术范畴，在此不再一一赘述。
实施例2
在使用根据实施例1的方法制备出显示基板之后，还可以进行以下步骤以制备显示面板：
在步骤S1，制备对向基板，所述对向基板用于与所述的显示基板对盒形成显示面板。
当显示基板指的是阵列基板时，对向基板可以指的是彩膜基板，反之亦然。另外，上述制备完成的阵列基板和彩膜基板朝向液晶的一侧都包括取向层4，对取向层4进行摩擦取向。取向层4的涂覆和摩擦均为现有技术范畴，在此不再一一赘述。
在步骤S2，在所述显示基板或对向基板上涂覆封框胶。
特别地，可以在所述彩膜基板2上与阵列基板1的显示区域的周边相对的区域涂覆封框胶5；当然也可以将封框胶5直接涂覆于阵列基板1的显示区域周边。可以根据实际情况选择具体的方案。
在步骤S3，将所述显示基板和对向基板对盒。
例如，将阵列基板1和涂覆封框胶5的彩膜基板2进行对盒，使所述彩膜基板2上的封框胶5包围所述阵列基板1上的显示区域，形成显示面板。对盒中可以采用对位装置，使每个显示面板的封框胶5包围显示区域。
在步骤S4，在所述显示基板和对向基板之间设置液晶。
在完成对盒的显示面板的显示区域滴注液晶形成液晶层3。应当理解的是，上述液晶的滴注也可以在对盒之前滴注到阵列基板1或彩膜基板2上。可以根据实际情况选择具体的方案。
应当理解的是，在上述液晶滴注的操作中可以采用液晶滴注装置和定位装置，其为现有技术范畴，在此不再一一赘述。
返回参考图1，可以对完成对盒的显示面板进行第二次紫外线照射完成封框胶5固化。特别地，第二次照射的紫外线的波长可以大于等于第一次照射的紫外线的波长，第二次照射的紫外线的照度可以小于等于第一次照射的紫外线的照度。
通过这样处理，被辐照的阵列基板1的金属层的电子不会产生第二次迁移，因为在第一次照射中电子已经完成了迁移并均匀分布在取向层4，第二次紫外线照射仅仅完成封框胶5的固化，不会产生阵列基板1的金属层的电子迁移。
因此，经过紫外线固化的显示面板的取向层4的电荷分布依然是均匀的，整个显示区域内对液晶分子的影响是一致的，不会产生亮度不均的缺陷，进而影响显示品质。
实施例3
根据本发明的另一方面，提供一种显示装置，所述显示装置包括使用上述的显示面板的制备方法制备的显示面板。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为落入本发明的保护范围。
