TFT-LCD包括四大项工艺：阵列工艺、彩膜工艺、成盒工艺、模组工艺。成盒工艺包括取向膜工程、框胶涂布、液晶滴注、真空贴盒及切割等制程。框胶涂布的目的是连接彩膜基板和阵列基板，防止液晶发生泄漏，保持周边盒厚。
框胶在使用前要进行脱泡处理，防止框胶中存在空气小泡，避免小气泡影响框胶的强度，保证在涂布过程中不出现断线。框胶涂布要保证框胶黏结性、涂布量的安定性、涂布位置安定性和液晶的相容性。框胶的主要成分是树脂，里面还添加了一些添加剂，如受热固化的单晶树脂和苯酚树脂，受紫外线照射起到交联作用的环氧树脂等等。根据添加剂种类，框胶分为热固化型和紫外固化型。热固化型强度高，但是固化时间长。紫外固化型固化速度快，但是强度低。现在TFT-LCD行业常用的是既添加了热固化树脂，又添加了紫外固化树脂。阵列基板与彩膜基板对盒后，随即进行紫外固化。紫外固化主要是让框胶外围迅速固化，这样即使接触到液晶也不至于引起不良。紫外固化后，再进行热固化，加强框胶的粘结力。
如图1和图2所示，在真空贴合制程后，进行框架固化，如果选择彩膜基板(第一基板120)侧照射紫外光进行框胶150紫外固化，在框胶150涂布的区域，彩膜基板侧的不透光层采用镂空设计，方便紫外线透过。
如图3所示，在框胶150涂布时，为保证首尾能够结合起来，一般会有首尾框胶150涂布的第一涂布区151，在第一涂布区151，其彩膜基板的镂空区122已经不能够满足紫外线照射进行框胶150的固化了。
下面参考附图和可选的实施例对本申请作说明。
如图4至图6所示，本申请实施例公布了一种显示面板110，形成于显示区111和外围区112，显示面板110包括：第一基板120；设有像素电极，与第一基板120对盒设置的第二基板130；形成于外围区112上，密封粘接第一基板120与第二基板130的框胶150；第一基板120包括遮光层121，遮光层121上设有镂空区122，镂空区122形成于外围区112；镂空区122与框胶150对应设置。
具体的，第一基板120是公共基板，公共基板上设有彩色色阻。
第一基板120和第二基板130通过框胶150密封粘接，框胶150的主要成分是树脂，里面添加了受紫外线照射起到交联作用的环氧树脂，第一基板120与第二基板130对盒后，随即对框胶150进行紫外固化。若从第一基板120侧照射紫外线对框胶150进行紫外固化，第一基板120上有遮光层121，遮光层121会遮挡住框胶150，紫外线照射不到框胶150，难以对框胶150固化，影响第一基板120和第二基板130的粘合力。
本方案中，在遮光层121上设有与框胶150对应的镂空区122，一方面，使从第一基板120侧照射的紫外线可以透过遮光层121的镂空区122照射到框胶150上，从而保证了框胶150的紫外固化效果，加强了第一基板120和第二基板130之间的粘合力，另一方面，第一基板120和第二基板130对盒时对框胶150压合，框胶150会填充到镂空区122内，增大了框胶150与镂空区122的接触面积，加强了框胶150和第一基板120之间的粘合力。
在一实施例中，镂空区122在第一基板120上的正投影完全覆盖框胶150在第一基板120上的正投影，且镂空区122的正投影面积大于框胶150的正投影面积。
本方案中，镂空区122在第一基板120上的正投影完全覆盖框胶150在第一基板120上的正投影，且镂空区122的正投影面积大于框胶150的正投影面积，保证了框胶150完全处于镂空区122中，紫外线从第一基板120照射到镂空区122时，可以保证框胶150受紫外线的照射充分，框胶150固化时间更快且效果更好。
在一实施例中，框胶150至少包括一个第一涂布区151和一个第二涂布区152，第一涂布区151的宽度大于第二涂布区152的宽度，第一涂布区151与第二涂布区152连接形成闭环结构；
第一基板120的镂空区122至少包括一个第一镂空区123和一个第二镂空区124，第一涂镂空区122与第二镂空区124连接形成闭环结构；第一镂空区123与第一涂布区151对应，第二镂空区124与第二涂布区152对应，第一镂空区123的宽度大于第二镂空区124的宽度。
本方案中，在框胶150涂布的过程中，为了保证第一基板120和第二基板130密封粘接，一般会在框胶150涂布的首尾部分重叠一段框胶150，使框胶150的首尾能够完全结合起来，重叠的这一段框胶150经压合后宽度比没重叠的涂布区的宽度更宽，第一涂布区151即框胶150重叠的涂布区，第二涂布区152即为框胶150未重叠的涂布区。为了保证变宽的第一涂布区151在紫外固化时能被紫外线完全照射到，对应的，在镂空区122设置了第一镂空区123与第一涂布区151对应，第二镂空区124与第二涂布区152对应，且第一镂空区123的宽度大于第二镂空区124的宽度。
在一实施例中，第一镂空区123的宽度大于第一涂布区151的宽度，第二镂空区124的宽度大于第二涂布区152的宽度。
本方案中，第一镂空区123的宽度大于第一涂布区151的宽度，保证第一涂布区151的框胶150可以被紫外线照射到，使第一涂布区151的框胶150的边缘快速固化；第二镂空区124的宽度大于第而涂布区的宽度，保证第二涂布区152的框胶150可以被紫外线照射到，使第二涂布区152的框胶150的边缘快速固化。
具体的，如图6所示，第一镂空区123可以设置2个或2个以上，可以方便框胶150从不同的位置开启涂布。
在一实施例中，第一基板120为彩膜基板140，第一基板120上的遮光层121由黑色色阻形成。在彩膜基板140的遮光层121对应框胶150的位置做镂空区122，既可以起到遮光作用，也可以方便对框胶150固化，且彩膜基板140的结构比阵列基板141简单，在彩膜基板140的遮光层121上做镂空制程简单，比在结构复杂的阵列基板141上做镂空良率更高。
作为本申请的另一实施例，参考图8和图9所示，与上述实施例不同在于，第一镂空区123在第一基板120上的正投影的边缘与第一涂布区151在第一基板120上的正投影的边缘不接触；
第二镂空区124在第一基板120上的正投影的边缘与第二涂布区152在第一基板120上的正投影的边缘不接触。
本方案中，第一涂布区151的正投影的边缘不与第一镂空区123的边缘接触，第二涂布区152的正投影的边缘不与第二镂空区124的边缘接触，保证框胶150涂布在镂空区122的中间位置，而不是镂空区122的边缘位置，避免了框胶150的边缘处照射不到紫外线，影响框胶150边缘的固化。
作为本申请的另一实施例，与上述实施例不同在于，第一镂空区123的宽度大于第一涂布区151的宽度与涂布误差值及对盒误差值之和，第一镂空区123的长度大于第一涂布区151的长度与涂布误差值及对盒误差值之和，第二镂空区124的宽度大于第二涂布区152的宽度与涂布误差值及对盒误差值之和。
本方案中，框胶150在涂布的时候会存在一定的误差值，使得涂布的框胶150偏离了预定的框胶150区，在第一基板120和第二基板130对盒的时候也会存在一定误差值，使得镂空区122与框胶150区的对应出现偏差，对框胶150紫外固化时，有部分框胶150照射不到紫外线，影响到框胶150的紫外固化效果。本方案中，充分考虑到以上诸多因素，设计镂空区122的宽度时，使镂空区122的宽度大于第一涂布区151的宽度与涂布误差值及对盒误差值之和，第一镂空区123的长度大于第一涂布区151的长度与涂布误差值及对盒误差值之和，第二镂空区124的宽度大于第二涂布区152的宽度与涂布误差值及对盒误差值之和，从而使得框胶150在涂布误差值和对盒误差值存在的情况下也能完全位于镂空区122，紫外固化时框胶150可以完全从镂空区122照射到紫外线，保证了框胶150紫外固化的效果。
作为本申请的另一实施例，参考图7至图9所示，第二基板130包括第一遮光层131，第一遮光层131包括与第一基板120的镂空区122对应设置的第三镂空区125，框胶150的所有区域至少被第一基板120镂空的遮光层121和/或第二基板130的镂空的第一遮光层131遮挡。
本方案中，第一基板120的遮光主要靠遮光层121，遮光层121在镂空区122做成镂空的地方就会出现漏光，为了避免漏光影响显示效果，在第二基板130上与镂空区122对应的位置设置遮光的第一遮光层131，实现了镂空区122的空隙与第一遮光层131的位置上下互补，保证了框胶150的全部区域都可以被镂空区122的实线和/或第一遮光层131遮挡住，在保证框胶150充分固化时又确保了第一基板120的镂空区122不漏光。
具体的，第二基板130上设有第三镂空区125，相当于框胶150既可以从第一基板120侧照射紫外线进行框胶150固化，也可以从第二基板130侧照射紫外线进行框胶150固化。
在一实施例中，如图8所示，第一基板120上的遮光层121包括黑色色阻，第二基板130上的第一遮光层125包括金属线。将第二基板130上的金属线作为第一遮光层131布局，使金属线与镂空区122在垂直方向对应互补，对镂空区122遮光，既实现了金属线导电的功能，也实现了遮光的功能，减少了第一遮光层131的制程。另外，金属线用作对镂空区122遮光作用的同时，在第一基板120和第二基板130对盒时，框胶150也会覆盖到相邻金属线之间的间隙内，增大了框胶150与金属线的接触面积，进而增大了框胶150与第二基板130之间的粘合力。
作为本申请的另一实施例，参考图10和图11所示，公布了一种显示面板110，形成有显示区111和外围区112，包括：彩膜基板140；阵列基板141，与彩膜基板140对盒设置；框胶150，形成于外围区112上，密封粘接彩膜基板140与阵列基板141；
彩膜基板140包括黑色色阻，黑色色阻在外围区112设置有第一镂空区123和第二镂空区124，第一镂空区123与第二镂空区124连接形成矩形的闭环结构，第一镂空区123比第二镂空区124的宽度大；阵列基板141在镂空区122对应的位置设有遮光的金属线；金属线与第一镂空区123和第二镂空区124在垂直方向上对应互补；
外围区112有涂布框胶150的第一涂布区151和第二涂布区152，第一涂布区151和第二涂布区152连接形成矩形的闭环结构，第一涂布区151比第二涂布区152的宽度大；
彩膜基板140的第一镂空区123与第一涂布区151对应，第一镂空区123在第一基板120上的正投影完全覆盖第一涂布区151在第一基板120上的正投影，第一镂空区123在第一基板120上的正投影的边缘与第一涂布区151在第一基板120上的正投影的边缘不接触；
彩膜基板140的第二镂空区124与第二涂布区152对应，第二镂空区124在第一基板120上的正投影完全覆盖第二涂布区152在第一基板120上的正投影，第二镂空区124在第一基板120上的正投影的边缘与第二涂布区152在第一基板120上的正投影的边缘不接触； 框胶150的所有区域被彩膜基板140的的第一镂空区123和第二镂空区124和/或阵列基板141的金属线遮挡。
彩膜基板140和阵列基板141通过框胶150密封粘接，框胶150的主要成分是树脂，里面添加了受紫外线照射起到交联作用的环氧树脂，彩膜基板140和阵列基板141对盒后，随即对框胶150进行固化。彩膜基板140上有黑色色阻遮光层121，若从彩膜基板140侧照射紫外线对框胶150进行紫外固化，遮光层121会遮挡住框胶150，紫外线照射不到框胶150，难以对框胶150固化，影响彩膜基板140和阵列基板141的粘合力，进而影响液晶特性。本方案在遮光层121上设有与框胶150的第一涂布区151和第二涂布区152对应的第一镂空区123和第二镂空区124，使从彩膜基板140侧照射的紫外线可以透过遮光层121的第一镂空区123和第二镂空区124照射到框胶150上，从而对框胶150进行紫外固化。
本方案中，在框胶150涂布的过程中，为了保证彩膜基板140和阵列基板141密封粘接，一般会在框胶150涂布的首尾部分重叠一段框胶150，使框胶150的首尾能够完全结合起来，重叠的这一段框胶150经压合后宽度比未重叠的涂布区的宽度更宽，第一涂布区151即框胶150重叠的涂布区，第二涂布区152即为框胶150未重叠的涂布区，与第一涂布区151对应的镂空区122更宽才能保证第一涂布区151的框胶150能充分接收到紫外线固化。
第一镂空区123与第一涂布区151对应，第二镂空区124与第二涂布区152对应，且第一镂空区123的面积大于第一涂布区151的面积，第二镂空区124的面积大于第二涂布区152的面积，且第一涂布区151完全位于第一镂空区123中，第二涂布区152完全位于第二镂空区124中，使得紫外线从彩膜基板140照射框胶150的涂布区时，从第一镂空区123和第二镂空区124照射进来的紫外线能完全照射到框胶150的表面，从而保证框胶150的固化效果。
具体的，彩膜基板140的第一镂空区123和第二镂空区124连接形成矩形闭环结构，第一涂布区151和第二涂布区152连接形成矩形闭环结构，闭环结构两两相邻的边都互相垂直。该闭环结构规则，方便镂空区122制程中对应的光罩做开口更方便，也方便框胶150的涂布操作。
如图5、图7至图9所示，第一涂布区151的宽度值为d1，涂布误差值为d2，对盒误差值为d3，第二涂布区152的宽度值为d4，第二镂空区124的长度值为L1，第一镂空区123的宽度值为D1，第二镂空区124的宽度值为D2，第二镂空区124的长度值为L2，则有：
D1≥d1+d2+d3；d4＞d1；D2≥d4+d2+d3；L2≥L1+d2+d3
其中，d1的范围为100-5000微米(um)；d2小于±500微米(um)具体尺寸范围可根据各个尺寸涂布的宽度、涂布机的性能而调整；d3小于±50微米(um)，具体尺寸范围可根据对盒制程能力而调整；d4的范围为100-10000微米(um)。
本申请的技术方案可以广泛用于各种显示面板，如扭曲向列型(Twisted Nematic，TN)显示面板、平面转换型(In-Plane Switching，IPS)显示面板、垂直配向型(Vertical Alignment，VA)显示面板、多象限垂直配向型(Multi-Domain Vertical Alignment，MVA)显示面板，当然，也可以是其他类型的显示面板，如有机发光二极管(Organic Light-Emitting Diode，OLED)显示面板，均可适用上述方案。
本申请的技术方案可以广泛用于TN面板(全称为Twisted Nematic，即扭曲向列型面板)、IPS面板(In-PaneSwitcing，平面转换)、VA面板(Multi-domain Vertica Aignment， 多象限垂直配向技术)，当然，也可以是其他类型的面板，适用即可。
以上内容是结合具体可选实施方式对本申请所作的详细说明，不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本申请的保护范围。
