Description

液晶面板及其制作方法 技术领域
本发明涉及液晶面板制作领域，特别是涉及一种良好支撑强度的液晶面板及其制作方法。
 背景技术
ODF（one drop filling：液晶滴下）制程是将液晶灌注与基板装配集为一体，液晶直接滴到基板上，不需要再开液晶注入口，因此ODF制程只需要经过滴液晶、压合、固化以及切片等几道工序即可完成液晶面板的制作，减少了工艺流程，缩短了产品生产周期，降低了生产成本。但是现有的ODF制程中，存在液晶面板的边缘与周边结构的间隙过大的问题，其原因主要是液晶面板的两基板之间的支撑不佳造成的液晶面板翘屈，一般通过增加两基板之间的支撑力来改善液晶面板的边缘间隙过大的问题。
现有的液晶面板的两基板之间的支撑力主要是由基板上的衬垫以及用于贴合两基板的框胶提供，通常会采用以下方法解决因两基板之间的支撑力不足而引起的液晶面板的边缘间隙过大的问题：
一、增大框胶内材料的粒径大小，以增加框胶的对两基板之间的支撑力；但是采用此法会造成液晶盒密封件使用量的增加，使得制作成本增加；
二、将液晶面板的密封件由封闭式密封改为开放式密封，以减小内外压差对两基板之间的支撑力的影响；但是采用此法易造成外界对液晶面板内部的污染，影响液晶面板的显示品质；
三、改变第一基板上的衬垫的分布以增加两基板之间的支撑力；由于衬垫通常使用光罩直接在第一基板上沉积生成，采用此法需要采用新的光罩或修改原有的光罩对第一基板上的衬垫位置进行改变，而修改光罩所费不赀，必然大幅增加液晶面板的成本。
故，有必要提供一种液晶面板及其制作方法，以解决现有技术所存在的问题。

图2为本发明的液晶面板的第二优选实施例的结构示意图；
图3为本发明的液晶面板的第三优选实施例的结构示意图；
图4为本发明的液晶面板的制作方法的优选实施例的流程图。
 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。
请参阅图1，其为本发明的液晶基板液晶面板的第一优选实施例的结构示意图，所述液晶基板液晶面板100包括第一基板110、第二基板120以及设置在第一基板110与第二基板120之间的液晶层（图未示）。第一基板110与第二基板120形成有显示区130以及设置在显示区130周围的非显示区140，在非显示区140设置有用于密封液晶层的主密封件150，在显示区130内设置有用于保持第一基板110和第二基板120之间的间隙的主衬垫160及通过喷墨方式注入的第一球状衬垫170，所述主衬垫160及第一球状衬垫170均设置在第一基板110上。在本实施例中，第一基板110为彩色滤光片(Color Filter，CF)基板，而第二基板120为薄膜晶体管(Thin Film Transistor，TFT)基板；或第一基板110为薄膜晶体管基板，而第二基板120为彩色滤光片基板。值得注意的是，在一些实施例中，彩色滤光片和TFT矩阵亦可设置在同一基板上。
本发明的液晶面板的显示区130同时设置有主衬垫160和第一球状衬垫170，大大加强了第一基板110与第二基板120之间的支撑强度。本发明通过设置第一球状衬垫170对两基板之间的支撑强度进一步加强，工序简单，费用低，同时不会对已生成的主衬垫160的使用产生影响。
优选的，所述第一球状衬垫170通过喷墨方式注入，当然也可以采用其他方式设置第一球状衬垫170。
作为本发明液晶面板的第一优选实施例，显示区130包括透光区和非透光区，光线可以从透光区射出而不能从非透光区射出。当主衬垫160为非透光材质时，主衬垫160设置在非透光区，当主衬垫160为透光材质时，主衬垫160则可以设置在显示区的任何位置；同理，当第一球状衬垫170为非透光材质时，其设置在非透光区内，当第一球状衬垫170为透光材质时，第一球状衬垫170则可以设置在显示区的任何位置。
在图2所示本发明液晶面板的第二优选实施例的结构示意图中，本实施例的液晶面板200与第一实施例的液晶面板100结构大致相同，其区别在于：在本实施例的液晶面板200在非显示区240还设置有次密封件280，所述次密封件280位于主密封件250的外侧，主密封件250和次密封件280之间设置有第二球状衬垫271。在本实施例中，在主密封件250和次密封件280之间设置第二球状衬垫271，可以进一步加强第一基板210与第二基板220之间的支撑强度。由于在第一基板210与第二基板220之间设置了主衬垫260、第一球状衬垫270以及第二球状衬垫271，使得无论液晶面板200的任何位置受到挤压变形，都有相应所述挤压变形的主衬垫260、第一球状衬垫270或第二球状衬垫271保持两基板之间的间隙以减小由于两基板之间的支撑不良造成的液晶面板200的边缘间隙过大。
与第一实施例相同，在本实施例中，所述主衬垫260、第一球状衬垫270可以是设置在透光区的透光材料制成或者是设置在非透光区的非透光材料制成的，而及第二球状衬垫271同样可以为透光材料或非透光材料制成。
在图3所示本发明液晶面板的第三优选实施例的结构示意图中，本实施例的液晶面板300与第二实施例的液晶面板200结构大致相同，其区别在于：在显示区330内还设置有次衬垫390，次衬垫390用于在液晶面板300受外力挤压时，减小第一基板310和第二基板320之间的相对运动。次衬垫390可以设置在第一基板310的透光区和/或非透光区，次衬垫390的高度小于主衬垫360的高度，只有当第二基板320受到外力，第一基板310和第二基板320之间发生相对运动时，次衬垫390的另一端才与第二基板320接触，起到保持两基板之间的间隙、使得第一基板310和第二基板320之间不会由于外力发生过度的相对运动的作用。因此设置有次衬垫390的液晶面板在受到外力过大的情况下可以通过次衬垫390进一步增加对两基板之间的支撑力以减小第二基板320受到外力时的第一基板310和第二基板320之间的相对运动。
本发明还涉及一种液晶面板的制作方法，请参阅图4，其为本发明的液晶面板的制作方法的优选实施例的流程图，所述液晶面板的制作方法包括以下步骤：
步骤401，提供一第一基板及第二基板，所述第一基板具有显示区及非显示区，在第一基板的显示区上形成主衬垫；
步骤402，在所述第一基板上设置第一球状衬垫；
步骤403，依次进行设置密封件、液晶滴下工序及第一基板与第二基板的贴合工序。
所述步骤401还包括在显示区内设置次衬垫，所述次衬垫用于在第二基板受外力时，减小所述第一基板和所述第二基板之间的相对运动。
所述步骤402具体为采用喷墨方式在显示区设置第一球状衬垫。
所述步骤403中，设置密封件包括在非显示区设置主密封件及次密封件，步骤402还包括采用喷墨方式在主密封件和次密封件之间设置第二球状衬垫。
本发明的液晶面板的制作方法同时在第一基板上设置主衬垫和第一球状衬垫，大大加强了两基板之间的支撑强度；本发明通过喷墨注入的方式形成第一球状衬垫，以进一步加强两基板之间的支撑强度，同时不会对已生成的主衬垫的使用产生影响，亦无需采用额外的光罩造成成本的增加。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
