Description

一种液晶面板及液晶显示装置 【技术领域】
本申请涉及显示技术领域，更具体的说，涉及一种液晶面板及液晶显示装置。
【背景技术】
液晶显示器具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。现有市场上的液晶显示器大部分为背光型液晶显示器，其包括液晶面板及背光模组(backlight module)。液晶面板的工作原理是在两片平行的玻璃基板当中放置液晶分子，并在两片玻璃基板上施加驱动电压来控制液晶分子的旋转方向，以将背光模组的光线折射出来产生画面。
其中，薄膜晶体管液晶显示器(Thin Film Transistor-Liquid Crystal Display，TFT-LCD)由于具有低的功耗、优异的画面品质以及较高的生产良率等性能，目前已经逐渐占据了显示领域的主导地位。同样，薄膜晶体管液晶显示器包含液晶面板和背光模组，液晶面板包括彩膜基板(Color Filter Substrate，CF Substrate，也称彩色滤光片基板)和薄膜晶体管阵列基板(Thin Film Transistor Substrate，TFT Substrate)，上述基板的相对内侧存在透明电极。两片基板之间夹一层液晶分子(Liquid Crystal，LC)。液晶面板是通过电场对液晶分子取向的控制，改变光的偏振状态，并藉由偏光板实现光路的穿透与阻挡，实现显示的目的。
现有彩膜基板在制造过程中，通过光阻涂布、曝光、显影、ITO、PS(photo spacer)等工艺形成CF基板成品。其中框胶与黑矩阵在剥落(Peeling)强度测试或PCT测试时往往结果都是黑矩阵剥落(Peeling)。
【发明内容】
本申请所要解决的技术问题是提供一种提高框胶的附着力的液晶面板。
此外，本申请还提供一种采用所述液晶面板的液晶显示装置。
本申请的目的是通过以下技术方案来实现的：一种液晶面板，包括彩膜基板，所述彩膜基板包括：
基板；
黑矩阵，所述黑矩阵设置在基板上；
第一凹槽，所述第一凹槽设置在黑矩阵上，所述第一凹槽贯穿黑矩阵，第一凹槽底面为基板，所述第一凹槽上设有黑色框胶。
其中，所述第一凹槽为连续环绕黑色框胶覆盖区域。连续凹槽可以更多的增加框胶与基板的接触面积。
其中，所述第一凹槽沿框胶覆盖区域间隔设置。框胶既可以增加与基板的接触面积，又可以很好的与黑矩阵连接。
其中，所述第一凹槽包括设置在黑矩阵四周的多个互不连接的子第一凹槽。可以在显示区的上下左右四个方向设置一个或多个子第一凹槽，也可以在四个角设置子第一凹槽，凹槽加工简单方便，增加框胶与基板的接触面积。
其中，所述彩膜基板还包括配向层，所述配向层设置在黑矩阵上，所述黑矩阵的第一凹槽内侧设有阻挡配向层的阻挡部。配向层扩散出去与框胶重叠，影响框胶的效果，利用阻挡部阻挡配向层外扩。
其中，所述阻挡部为第二凹槽。阻挡部可以是在黑矩阵上开设第二凹槽。
其中，所述第二凹槽开口处覆盖有遮光层；所述遮光层采用与黑色框胶相同的材质。第二凹槽也贯穿黑矩阵会导致漏光，使用遮光层进行涂布，以防止漏光，遮光层采用与黑色框胶相同的材质可以在设置黑色框胶的一同实施，不需要额外的材料，减少采购成本和采购数量，不容易出错，第二凹槽如果为盲槽，底部还是黑矩阵，没有漏光，但是黑矩阵厚度变薄了，上面再覆盖遮光层，效果更佳。
其中，所述阻挡部为凸台。阻挡部可以是在黑矩阵上设置凸台阻挡，如黑矩阵中间高度高于两侧，黑矩阵外侧高度高于内侧，还可以在框胶内侧设置一圈阻挡配向层扩散的内层框胶，不需要更换设备只需在正常框胶内侧再设置一 圈。
其中，所述液晶面板还包括背光模组，所述背光模组上设置阵列基板，所述阵列基板与彩膜基板相对设置，所述彩膜基板和阵列基板通过框胶连接，所述彩膜基板上还设有与黑矩阵错开设置的彩色滤光层，所述阵列基板与彩膜基板之间设有液晶和PS，所述阵列基板上设有薄膜晶体管，所述彩色滤光层、液晶、PS和薄膜晶体管设置在框胶内。
根据本申请的另一个方面，本申请还公开了一种液晶显示装置，包括如上述任一项所述的液晶面板。
黑矩阵上开设第一凹槽，第一凹槽底面为基板，黑色框胶设置在第一凹槽上，这样黑色框胶与黑矩阵连接一侧可以直接与基板连接，增加框胶与基板的接触面积，框胶对于基板的附着力远大过于框胶对于黑矩阵的附着力，由于在黑矩阵上开设第一凹槽后会导致漏光，使用黑色框胶进行涂布，以防止漏光，如此黑色框胶可以很好的将彩膜基板和阵列基板粘粘固定，提高框胶与黑矩阵的连接强度，增强PCT和剥落(Peeling)测试强度。

下面结合附图和较佳的实施例对本申请作进一步说明。
其中，如图1a和图1b所示的两种热辅助固化材料的应用(application of the heat auxiliary curable type)，1a为透明框胶；1b为黑色框胶。对比普通透明框胶，黑色框胶具备遮光效果。其中黑色框胶，光密度OD 5um/2.5，BM光密度OD约在4～5。
如图2所示，在图2所示的实施例中液晶面板包括阵列基板30和彩膜基板40，所述阵列基板30与彩膜基板40相对设置，所述彩膜基板40和阵列基板30通过框胶14连接，所述彩膜基板40上还设有与黑矩阵11错开设置的彩色滤光层18，所述阵列基板30与彩膜基板40之间设有液晶16和PS17(photo spacer)，所述阵列基板30上设有薄膜晶体管，所述彩色滤光层18、液晶16、PS17(photo spacer)和薄膜晶体管设置在框胶14内。当然液晶面板也可包括背光模组20，背盖模组19上设置阵列基板30，阵列基板30与彩膜基板40相对设置。基板1的材料可为玻璃、塑料等。
如图3和图4所示，在图3和图4所示的实施例中彩膜基板包括：基板10、黑矩阵11和第一凹槽13，所述黑矩阵11设置在基板10上；所述第一凹槽13设置在黑矩阵11上，所述第一凹槽13贯穿黑矩阵11，第一凹槽13底面为基板10，所述第一凹槽13上设有黑色框胶14。
本实施例在黑矩阵11上开设第一凹槽，第一凹槽底面为基板10，黑色框胶14设置在第一凹槽上，这样黑色框胶14与黑矩阵11连接一侧可以直接与基板10连接，增加框胶与基板10的接触面积，框胶对于基板10的附着力远大过于框胶对于黑矩阵11的附着力，由于在黑矩阵11上开设第一凹槽后会导致漏光，使用黑色框胶14进行涂布，以防止漏光，如此黑色框胶14可以很好的将彩膜基板和阵列基板粘粘固定，提高框胶与黑矩阵11的连接强度，增强PCT和剥落(Peeling)测试强度。此外，现行在窄边框设计框胶必落于黑矩阵11(BM)上， 加上FSA制程UV灯管需要UV MASK否则就要上可视光胶，制程工艺上有一定的难度进而影响框胶的强化。如今在彩膜基板(CF)黑矩阵11(BM)开槽就可避免该问题，还可以减少制程限制，框胶的紫外线硬化(UV Curing)可从TFT侧的阵列基板照射，也可以从彩膜基板(CF)侧照射，窄边框制成固化(Curing)照射CF侧，可以减少影部硬化不足之问题。
黑色框胶除了具备框胶原有特性外还须兼顾黑色框胶本身透光度，起到遮光的效果，最好能达到黑矩阵一样的遮光效果，黑色框胶影部硬化性与一般胶材一致或接近，根据黑色框胶对液晶面板工艺和治具进行调整，以符合液晶面板的各项参数指标。
如图2至图4所示，在图2至图4所示的实施例中液晶面板包括阵列基板30和彩膜基板40，所述阵列基板30与彩膜基板40相对设置，所述彩膜基板40和阵列基板30通过框胶14连接，所述彩膜基板40上还设有与黑矩阵11错开设置的彩色滤光层18，所述阵列基板30与彩膜基板40之间设有液晶16和PS17(photo spacer)，所述阵列基板30上设有薄膜晶体管，所述彩色滤光层18、液晶16、PS17(photo spacer)和薄膜晶体管设置在框胶14内。当然液晶面板也可包括背光模组20，背盖模组19上设置阵列基板30，阵列基板30与彩膜基板40相对设置。基板1的材料可为玻璃、塑料等。

其中，第一凹槽13沿框胶覆盖区域间隔设置。框胶既可以增加与基板10的接触面积，又可以很好的与黑矩阵11连接，如此一来便可增加10％～20％框胶跟玻璃的接触面积，以增加面板PCT/Peeling TEST强度。所述第一凹槽13也可以包括设置在黑矩阵11四周的多个互不连接的子第一凹槽。可以在显示区12的上下左右四个方向设置一个或多个子第一凹槽，也可以在四个角设置子第一 凹槽，凹槽加工简单方便，增加框胶与基板10的接触面积。
一般TV设计BM CD约在5000～6000um，框胶线宽约在1200～1500um，开槽宽度约在500～1000um。第一凹槽13宽度小于框胶14宽度，不影响框胶14原有功能的情况下限制框胶14的宽度，提高框胶14的线宽制程能力。
本实施例在黑矩阵11上开设第一凹槽，第一凹槽底面为基板10，黑色框胶14设置在第一凹槽上，这样黑色框胶14与黑矩阵11连接一侧可以直接与基板10连接，增加框胶与基板10的接触面积，框胶对于基板10的附着力远大过于框胶对于黑矩阵11的附着力，由于在黑矩阵11上开设第一凹槽后会导致漏光，使用黑色框胶14进行涂布，以防止漏光，如此黑色框胶14可以很好的将彩膜基板和阵列基板粘粘固定，提高框胶与黑矩阵11的连接强度，增强PCT和剥落(Peeling)测试强度。此外，现行在窄边框设计框胶必落于黑矩阵11(BM)上，加上FSA制程UV灯管需要UV MASK否则就要上可视光胶，制程工艺上有一定的难度进而影响框胶的强化。如今在彩膜基板(CF)黑矩阵11(BM)开槽就可避免该问题，还可以减少制程限制，框胶的紫外线硬化(UV Curing)可从TFT侧的阵列基板照射，也可以从彩膜基板(CF)侧照射，窄边框制成固化(Curing)照射CF侧，可以减少影部硬化不足之问题。
黑色框胶除了具备框胶原有特性外还须兼顾黑色框胶本身透光度，起到遮光的效果，最好能达到黑矩阵一样的遮光效果，黑色框胶影部硬化性与一般胶材一致或接近，根据黑色框胶对液晶面板工艺和治具进行调整，以符合液晶面板的各项参数指标。

其中，所述第一凹槽13为连续环绕黑色框胶14覆盖区域。第一凹槽13围绕显示区12设置，连续凹槽可以更多的增加框胶与基板10的接触面积。
一般TV设计BM CD约在5000～6000um，框胶线宽约在1200～1500um，开槽宽度约在500～1000um。第一凹槽13宽度小于框胶14宽度，不影响框胶14原有功能的情况下限制框胶14的宽度，提高框胶14的线宽制程能力。
本实施例在黑矩阵11上开设第一凹槽，第一凹槽底面为基板10，黑色框胶14设置在第一凹槽上，这样黑色框胶14与黑矩阵11连接一侧可以直接与基板10连接，增加框胶与基板10的接触面积，框胶对于基板10的附着力远大过于框胶对于黑矩阵11的附着力，由于在黑矩阵11上开设第一凹槽后会导致漏光，使用黑色框胶14进行涂布，以防止漏光，如此黑色框胶14可以很好的将彩膜基板和阵列基板粘粘固定，提高框胶与黑矩阵11的连接强度，增强PCT和剥落(Peeling)测试强度。此外，现行在窄边框设计框胶必落于黑矩阵11(BM)上，加上FSA制程UV灯管需要UV MASK否则就要上可视光胶，制程工艺上有一定的难度进而影响框胶的强化。如今在彩膜基板(CF)黑矩阵11(BM)开槽就可避免该问题，还可以减少制程限制，框胶的紫外线硬化(UV Curing)可从TFT侧的阵列基板照射，也可以从彩膜基板(CF)侧照射，窄边框制成固化(Curing)照射CF侧，可以减少影部硬化不足之问题。

所述彩膜基板还包括配向层15，所述配向层15设置在黑矩阵11上，所述黑矩阵11的第一凹槽13内侧设有阻挡配向层15的阻挡部20。配向层15扩散出去与框胶重叠，影响框胶的效果，利用阻挡部20阻挡配向层15外扩。
所述阻挡部20为第二凹槽。阻挡部20可以是在黑矩阵11上开设第二凹槽。所述第二凹槽开口处覆盖有遮光层；所述遮光层采用与黑色框胶14相同的材质。第二凹槽也贯穿黑矩阵11会导致漏光，使用遮光层进行涂布，以防止漏光，遮光层采用与黑色框胶14相同的材质可以在设置黑色框胶14的一同实施，不需要额外的材料，减少采购成本和采购数量，不容易出错，第二凹槽如果为盲槽，底部还是黑矩阵11，没有漏光，但是黑矩阵11厚度变薄了，上面再覆盖遮光层，效果更佳。所述阻挡部20也可以为凸台。阻挡部20可以是在黑矩阵11上设置凸台阻挡，如黑矩阵11中间高度高于两侧，黑矩阵11外侧高度高于内侧，还可以在框胶内侧设置一圈阻挡配向层15扩散的内层框胶，不需要更换设备只需在正常框胶内侧再设置一圈。
一般TV设计BM CD约在5000～6000um，框胶线宽约在1200～1500um，开槽宽度约在500～1000um。第一凹槽13宽度小于框胶14宽度，不影响框胶14原有功能的情况下限制框胶14的宽度，提高框胶14的线宽制程能力。
其中，第一凹槽13沿框胶覆盖区域间隔设置。框胶既可以增加与基板10的接触面积，又可以很好的与黑矩阵11连接，如此一来便可增加10％～20％框胶跟玻璃的接触面积，以增加面板PCT/Peeling TEST强度。
第一凹槽13也可以为连续环绕黑色框胶14覆盖区域。第一凹槽13围绕显示区12设置，连续凹槽可以更多的增加框胶与基板10的接触面积。所述第一凹槽13也可以包括设置在黑矩阵11四周的多个互不连接的子第一凹槽。可以在显示区12的上下左右四个方向设置一个或多个子第一凹槽，也可以在四个角设置子第一凹槽，凹槽加工简单方便，增加框胶与基板10的接触面积。
