Description

液晶显示装置、液晶显示面板的制造方法及设备
【技术领域】
本发明涉及液晶显示技术领域，特别是涉及一种液晶显示装置、液晶显示面板的制造方法及设备。
【背景技术】
PSVA（Polymer Stabilization Vertical Alignment,聚合物稳定垂直对齐）广视角技术能够使显示面板具有较好的黑态、较快的响应时间以及穿透率高等优点，因此PSVA型液晶显示面板相较于传统液晶显示面板而言，其显示效果更佳，能给用户带来更高的视觉体验，已逐渐成为液晶显示面板主流的发展方向之一。
PSVA型液晶显示面板的PSVA制程中通常需要在上下基板间的液晶分子或配向膜（PI，Polyimide）中掺入对光线敏感的单体分子（Monomer），通过对单体分子进行紫外光照射或加热使单体分子向PI配向膜表面凝结，从而使液晶分子具有预倾角。
在进行PSVA制程之前，液晶显示面板还需经过一道框胶紫外光固化（SUV，Sealant Ultra-Violet）制程。在这过程中，参阅图1，上基板11和下基板12通过框胶14粘合在一起形成组立面板。粘合后，需要使用紫外光（UV，Ultra-Violet Ray）13照射框胶，使框胶14固化。在紫外光13照射框胶14而使框胶14固化的过程中，需要一个防紫外光掩膜（UV Mask，Ultra-Violet Ray Mask）16去阻挡紫外光13的照射以避免可视区（Active area）17的液晶分子15中的单体分子（图未示）在PSVA制程之前受到紫外光13的照射而提前反应掉，即所谓的预固化（Pre-cured）作用。防紫外光掩膜16阻挡的是可视区17的紫外光照射，由于不可避免的会有斜向光线的作用，以及受防紫外光掩膜的制作或对位精度的影响，紫外光13会照射到可视区17边界的液晶分子15。
上基板11和下基板12之间构成电容而使得上下基板间存在电场，液晶分子15在电场的作用下会发生一定的偏转。当紫外光13照射到可视区17边界的液晶分子15时，使得可视区17周围边界的液晶分子15会因为单体分子的提前反应而固化在具有一定偏转角的状态，以至于不能垂直配向层（PI，Polyimide）表面，使得其与大部分可视区17的液晶分子不同（如图2所示），使得可视区17周围边界有画面不均匀或碎亮点的现象发生，在后续阶段会形成所谓的周边色差（Around Mura）。此时，必须将防紫外光掩膜16的边界距离可视区17边界一段距离，使可视区17边界的液晶分子15不会被紫外光13照射到。但是，使防紫外光掩膜16的边界距离可视区17的边界一段距离，则不利于显示面板的窄边设计。
【发明内容】
本发明主要解决的技术问题是提供一种液晶显示装置、液晶显示面板的制造方法及设备，能够较好地改善液晶显示面板周围画面不均匀的现象，减少碎亮点的发生，同时也能够更容易实现液晶显示面板的窄边设计。

【具体实施方式】
本发明的液晶显示面板的制造方法能够较好地改善液晶显示面板周围画面不均匀的现象，减少碎亮点的发生，同时也能够更容易实现液晶显示面板的窄边设计。
下面将结合附图和实施方式对本发明进行详细描述。
参阅图3，本发明液晶显示面板的制造方法的一实施方式，包括步骤：
步骤S101：在液晶显示面板的下基板的PSVA测试垫的位置涂布具有导电性的第一框胶，或者在液晶显示面板的上基板对应下基板的PSVA测试垫的位置涂布具有导电性的第一框胶，并且将上下基板通过第二框胶进行粘合形成组立面板，使PSVA测试垫通过第一框胶与上基板的透明电极电连接，第二框胶位于第一框胶以内的区域之内。
在PSVA模式的液晶显示面板制程中，如图4所示，首先在下基板201的边缘设置PSVA测试垫2011，以在后续PSVA制程中通过PSVA测试垫2011施加电压进行PSVA测试。然后通过涂布工具在PSVA测试垫2011的位置涂布具有导电性的第一框胶2012。第一框胶2012由较特殊的框胶材料制成，在一应用例中，其框胶主体中具有导电粒子，使其具有导电性，而本发明也正是利用了第一框胶2012的导电性来实现本发明之技术效果。本实施方式中，第一框胶2012还具有无固化属性，使其不会因为光照射或加热而固化。
对下基板201的PSVA测试垫2011的位置涂布具有导电性的第一框胶2012后，在下基板201的可视区2014的边界，并且在第一框胶2012以内的区域之内涂布第二框胶2013，然后将下基板201和上基板202通过第二框胶2013进行上下粘合形成组立面板203（如图5所示）。其中，第二框胶2013具有较好的黏着度，以将下基板201和上基板202牢固粘合在一起。
而由于第一框胶2012具有导电性，在下基板201和上基板202通过第二框胶2013粘合在一起形成组立面板203时，下基板201的PSVA测试垫2011能够通过第一框胶2012与上基板202的透明电极2021电连接。
当然，如图6所示，其他实施方式中的具有导电性的第一框胶3021还可以涂布在液晶显示面板的上基板302对应下基板301的PSVA测试垫3011的位置，且该位置设置有上基板302的透明电极3024，第一框胶3021与透明电极3024电连接。而第二框胶3022也可以涂布在上基板302的可视区3023的边界处，并且第二框胶3022位于第一框胶3021以内的区域之内。在上基板302和下基板301通过第二框胶3022进行粘合形成组立面板303时，下基板301的PSVA测试垫3011也能够通过第一框胶3021与上基板302的透明电极3024电连接。
步骤S102：在上基板或下基板一侧遮挡组立面板的第二框胶所围成的区域，并对组立面板进行曝光以固化第二框胶。
参阅图7，并结合图5，图7是图5中的组立面板沿AB方向进行紫外光照射的截面图，在形成组立面板203后，进入对液晶显示面板的框胶进行紫外光固化的制程。第二框胶2013对光线敏感，在光的照射下可固化。因此，通过对组立面板203进行紫外光照射以固化第二框胶2013，并且在紫外光照射组立面板203对第二框胶2013进行固化之后，对组立面板203进行加热以进一步固化第二框胶2013。在进行紫外光照射之前，使用防紫外光掩膜601在上基板202一侧遮挡组立面板203的第二框胶2013所围成的区域，即上基板202的可视区602，以防止框胶紫外光固化制程的紫外光照射到可视区602中的单体分子（图未示）而使得单体分子在PSVA制程之前反应掉。
值得注意的是，为方便、统一操作，其他实施方式中的第一框胶2012也可以采用与第二框胶2013一样的材料制作，即也具有一定的固化属性，在遇到光照射的情况下第一框胶2012也会固化。此时，在进行框胶紫外光固化制程的紫外光照射时，也应使用防紫外光掩膜遮挡第一框胶2012，防止第一框胶2012固化而在后续将其移除时造成不顺利。
在固化第二框胶2013之后，如图9所示，将上基板202对应下基板201的PSVA测试垫2011区域的部分切除，并一同移除第一框胶2012，使得下基板201的PSVA测试垫2011裸露，为后续PSVA制程创造条件。此外，第二框胶2013还可以具有较大的第二粘着力以提高上下基板粘合的紧密性，而第一框胶2012具有较小的第一黏着力。即第一黏着力小于第二黏着力，使得第一黏着力不会影响切除上基板202对应下基板201的PSVA测试垫2011区域的部分的动作，也能够较容易移除第一框胶2012。
本实施方式中，将下基板201的PSVA测试垫2011通过具有导电性的第一框胶2012与上基板202的透明电极2021电连接，使得在PSVA制程之前下基板201和上基板202之间为等电位，即不存在电压差，从而使上下基板间的液晶分子自然地垂直配向层（图未示）表面而不会发生偏转角。此时，当对组立面板203进行紫外光照射而固化第二框胶2013时，即使紫外光照射到组立面板203可视区边界处的液晶分子中的单体分子，单体分子发生反应也不会使液晶分子形成偏转角，而只是使可视区边界处的液晶分子固化在垂直配向层表面的偏转状态，进而使得可视区边界处的液晶分子在框胶紫外光固化制程之后、PSVA制程之前与大部分可视区的液晶分子具有相同的偏转状态（如图8所示）。因此，本发明液晶显示面板的实施方式能够较好地改善液晶显示面板可视区周围画面不均匀的现象，减少碎亮点的发生，而防紫外光掩膜的边界也不需要距离可视区边界较远距离，即可以使可视区边界更加靠近防紫外光掩膜的边界，甚至可以使可视区边界与防紫外光掩膜的边界重合，因此也能够更容易实现液晶显示面板的窄边设计。
本发明还提供一种液晶显示装置的制造方法的实施方式，包括上述各实施方式所述的液晶显示面板的制造方法。
参阅图10，并结合图4，本发明液晶显示面板的制造设备的一实施方式，包括：

遮光机构1002，用于在上基板202或下基板201一侧遮挡组立面板203的第二框胶2013所围成的区域，以防止紫外光照射到第二框胶2013所围成的区域；
