Description

显示面板及显示装置
【技术领域】
本发明涉及领域，特别是涉及液晶显示领域，尤其涉及一种显示面板及显示装置。
【背景技术】
相比于传统的液晶面板，采用COA（color filter on array）技术的液晶面板因彩色滤光片整合在阵列基板上，所以不存在彩色滤光片单元与像素电极未严格对准的问题，可以提高液晶面板的开口率，增加液晶面板的亮度。现在，将窄边框设计应用于这种面板上，可以进一步提升其显示水平。
将液晶面板的边框做窄的关键是将框胶做窄，然而，框胶做窄后，与两个基板之间的接触面积势必减小，这就导致框胶对基板的粘结力减小，可能会出现液晶盒漏晶甚至出现开盒等不良现象。因此，如何提高框胶对基板的粘结力、以便于实现液晶面板的窄边框设计成为急需解决的问题。

实施例1
参阅图1，图1是本发明显示面板的第一实施例的俯视示意图，图2是图1所示显示面板A-A向的局部剖视示意图。本实施方式中，显示面板100包括第一基板11、第二基板12、框胶13和间隔体14。
第一基板11上设置第一框胶涂布区（未标示），第二基板12与第一基板11正对，且设置与第一框胶涂布区正对的第二框胶涂布区（未标示）。第一基板11和第二基板12的形状相似且面积全等，第一框胶涂布区与第二框胶涂布区形状相似且面积全等。
本实施例中，第一框胶涂布区呈矩形框状，包括首尾相接的四条涂布带（未标示）。第一框胶涂布区上设置凹槽111，凹槽111亦呈连续的矩形框状。优选地，凹槽111的宽度小于第一框胶涂布区的宽度。在其他的实施例中，第一框胶涂布区上沿首尾相接的四条涂布带的长度方向亦可以间断的设置多个凹槽111。
间隔体14的一端与凹槽111的底面固定连接。优选地，间隔体14采用光阻材料经显影、曝光、蚀刻等步骤形成于第一基板11的凹槽111中，从而与第一基板11固定连接，固定连接于凹槽111中的间隔体14还可以起到保护凹槽111下方的金属线路的目的。
本实施例中，第一框胶涂布区的四条涂布带的凹槽111中均设置间隔体14，进一步地，每一涂布带的凹槽111中均设置多个间隔体14。以及，优选地，两条涂布带相交位置处的凹槽111中设置有间隔体14。本实施例中，间隔体14的另一端与第二基板12的表面接触。
框胶14填充于第一框胶涂布区和第二框胶涂布区之间以连接第一基板11和第二基板12且在两基板间形成密封的液晶填充区。
间隔体14的设置使得框胶14的接触面积增大，能够有效强化窄边框设计面板的信赖性。
实施例2
参阅图3，图3是本发明显示面板第二实施例的局部剖视示意图。本实施方式中，显示面板包括第一基板21、第二基板22、框胶23和间隔体24。
第一基板21上设置第一框胶涂布区（未标示），第二基板22与第一基板21正对，且设置与第一框胶涂布区正对的第二框胶涂布区（未标示）。第一基板21和第二基板22的形状相似且面积全等，第一框胶涂布区与第二框胶涂布区形状相似且面积全等。
本实施例中，第一框胶涂布区呈矩形框状，包括首尾相接的四条涂布带（未标示）。第一框胶涂布区上设置凹槽211，凹槽211亦呈连续的矩形框状。优选地，凹槽211的宽度小于第一框胶涂布区的宽度。在其他的实施例中，第一框胶涂布区上沿首尾相接的四条涂布带的长度方向亦可以间断的设置多个凹槽211。
第二框胶涂布区上设置凹槽211。凹槽211可以呈连续的矩形框状。或者，第二框胶涂布区上沿其首尾相接的四条涂布带的长度方向间断设置多个凹槽221。
间隔体24的一端与凹槽211的底面固定连接。优选地，间隔体24采用光阻材料经显影、曝光、蚀刻等步骤形成于第一基板21的凹槽211中，从而与第一基板21固定连接，固定连接于凹槽211中的间隔体24还可以起到保护凹槽211下方的金属线路的目的。
本实施例中，第一框胶涂布区的四条涂布带的凹槽211中均设置间隔体24，进一步地，每一涂布带的凹槽211中均设置多个间隔体24。以及，优选地，两条涂布带相交位置处的凹槽211中设置有间隔体24。本实施例中，间隔体24的另一端延伸至第二基板22的凹槽221中且与其底面接触。
在其他的实施例中，一部分间隔体24固定连接于凹槽211中，而另一部分间隔体24固定连接于凹槽221中；换句话说，一部分间隔体24设置于凹槽211中，另一部分间隔体设置于凹槽221中。优选地，间隔体24可以以交错的方式间隔固定连接于凹槽211和凹槽221中。具体而言，即，一部分间隔体24采用光阻材料经显影、曝光、蚀刻等步骤形成于第一基板21的凹槽211中，从而与第一基板21固定连接，而另一部分间隔体21采用光阻材料经显影、曝光、蚀刻等步骤形成于第二基板22的凹槽221中，从而与第二基板22固定连接，第一基板21和第二基板22对盒时，每一固定连接于第一基板21上的间隔体24的相邻两个间隔体均固定连接于第二基板上，每一固定连接于第二基板22上的间隔体24的相邻的两个间隔体均固定连接于第一基板21上。
框胶24填充于第一框胶涂布区和第二框胶涂布区之间以连接第一基板21和第二基板22且在两基板间形成密封的液晶填充区。
间隔体24的设置使得框胶24的接触面积增大，能够有效强化窄边框设计面板的信赖性。
实施例3
参阅图4，图4是本发明显示面板第三实施例的局部剖视示意图。本实施方式中，显示面板包括第一基板31、第二基板32、框胶33和间隔体34。
第一基板31上设置第一框胶涂布区（未标示），第二基板32与第一基板31正对，且设置与第一框胶涂布区正对的第二框胶涂布区（未标示）。第一基板31和第二基板32的形状相似且面积全等，第一框胶涂布区与第二框胶涂布区形状相似且面积全等。
本实施例中，第一框胶涂布区呈矩形框状，包括首尾相接的四条涂布带（未标示）。第一框胶涂布区上设置凹槽311，凹槽311亦呈连续的矩形框状。优选地，凹槽311的宽度小于第一框胶涂布区的宽度。在其他的实施例中，第一框胶涂布区上沿首尾相接的四条涂布带的长度方向亦可以间断的设置多个凹槽311。
间隔体34的一端与凹槽311的底面固定连接。优选地，间隔体34采用光阻材料经显影、曝光、蚀刻等步骤形成于第一基板31的凹槽311中，从而与第一基板31固定连接，固定连接于凹槽311中的间隔体34还可以起到保护凹槽311下方的金属线路的目的。
本实施例中，第一框胶涂布区的四条涂布带的凹槽311中均设置间隔体34，进一步地，每一涂布带的凹槽311中均设置多个间隔体34。以及，优选地，两条涂布带相交位置处的凹槽311中设置有间隔体34。本实施例中，间隔体34的另一端与第二基板32之间有一预设间距，且间隔体34的另一端具有凹凸结构。
框胶34填充于第一框胶涂布区和第二框胶涂布区之间以连接第一基板31和第二基板32且在两基板间形成密封的液晶填充区。
间隔体34的设置使得框胶34的接触面积增大，能够有效强化窄边框设计面板的信赖性。间隔体34的另一端的凹凸结构设计进一步增大了框胶34的接触面积。
实施例4
参阅图5，图5是本发明显示面板的第一实施例的俯视示意图。本实施方式中，显示面板包括第一基板、第二基板42、框胶43和间隔体44。第一基板上设置凹槽411。
第一基板、第二基板的结构请参照第一至第三实施例。在本实施例中，间隔体44的结构至少包括两种，从俯视图上看，间隔体有椭圆截面柱体状的和矩形截面柱体状的。
本示例的至少表明在显示面板的制造过程中为了增大框胶的接触面积，不限制间隔体44的规格和形状。
区别于现有技术，本发明显示面板在第一基板的第一框胶涂布区上设置第一凹槽，并且设置与第一凹槽的底面固定连接的间隔体，从而使得框胶不仅与第一基板和第二基板接触，亦与固定设置于第一基板上的间隔体接触，增大了框胶的接触面积，因此，能够有效提高框胶对基板的粘结力；进一步地，设置于框胶涂布区的间隔体对第一基板和第二基板提供了辅助支撑的作用，能够防止盒厚的改变。本发明特别适用于窄边框显示面板，能够有效提高窄边框显示面板两基板间的粘结力。
本发明进一步提供一种显示装置，该显示装置包括前述实施例中详细描述的显示面板。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
