Description

显示面板及其制备方法 技术领域

 背景技术
随着人们生活越来越智能化，显示屏作为人机互动的窗口越来越多的出现在人们的生活中。LCD制程中为了节省成本，越来越广泛的将导电偏光片应用于液晶显示技术的新产品上。
现有设计中，对于触摸面板功能嵌入到液晶像素中的方法（In cell touch）的设计，导电偏光片的使用节省了高阻膜的制作工艺成本。导电偏光片需涂布导电胶实现偏光片与阵列基板导通。如图1所示，偏光片是由几层薄膜依次贴附形成，一般由下至上为：硬膜（HC膜）、三醋酸纤维素酯（TAC膜）、聚乙烯醇（PVA膜）以及三醋酸纤维素酯（TAC膜），其中，最中间的一般是PVA膜。一般在制作显示面板的时候，先偏贴偏光片然后再涂布导电胶，这会导致无法控制导电胶贴附偏光片侧面的位置，进一步会导致导电胶接触偏光片中的PVA膜。在高温高湿的信赖性实验中，导电胶中酸性物质溶水汽后会腐蚀碱性的PVA膜表面，从而导致导电胶渗透至偏光片中出现气泡不良。并且，在制作的时候，使得偏光片的侧面预留一定区域贴附导电胶，这也间接的减小的偏光片的尺寸。
因此，有必要提出一种新的显示面板，提高显示面板的信赖性以及偏光片的尺寸，可以解决导电胶渗透至偏光片而出现气泡不良的问题。

这样，本发明通过设置所述第二导电体1102b被所述连接层106靠近所述引脚区110的一边覆盖，并不会使得制备所述第二导电体1102b接触到所述偏光片111的偏光层109。并且所述偏光片111采用全面覆盖所述透明电极层，所述偏光片111的尺寸较现有技术加大。
本发明还提供一种显示面板的制备方法，包括步骤S1~S7：
S1、提供第一基板101、彩色滤光片104、偏光片111以及玻璃盖板108。
所述第一基板101为TFT基板，所述第一基板101的材料为聚酰亚胺；所述第一基板101具有柔性的特性。
所述偏光片111的作用是将不具有偏极性的自然光转化为偏振光，透过液晶的转向，来控制光线的穿透与否，进而产生液晶面板明暗的显示效果。所述偏光片111为导电偏光片111。
S2、在所述第一基板101上设置一接地引脚1101。
S3、在所述第一基板101和所述彩色滤光片104之间形成液晶层102。
S4、在所述第一基板101和所述彩色滤光片104之间形成框胶103，所述框胶103包围所述液晶层102。
所述框胶103可以粘合所述第一基板101以及所述彩色滤光片104，并形成盒状结构。
S5、涂覆导电胶于所述接地引脚1101上形成一导电块1102，所述导电块1102连接所述偏光片111。
所述偏光片111包括一偏光层109、至少一连接层106以及导电层105，所述连接层106设于所述偏光层109与所述导电层105之间。
所述导电层105的材料为所述导电层的材料为高阻膜或压敏胶；所述高阻膜材料为氧化铟锡、氧化铟锌或氧化铝锌。并且所述导电层105为透明层，可以增加光线的透过率。
所述导电块1102通过喷嘴式打印或油墨打印方法制备。所述导电块1102的材料为具有银金属元素的导电胶。
所述导电块1102包括第一导电体1102a与第二导电体1102b，所述第一导电体1102a连接所述第二导电体1102b；所述第一导电体1102a具有第一面1103以及第二面1104，所述第一面1103垂直所述第二面1104。
所述第一面1103贴附所述接地引脚1101，所述第二面1104贴附所述框胶103以及所述彩色滤光片104侧面。所述第二导电体1102b设于所述导电层105与所述偏光片111之间；所述第二导电体1102b与所述第一导电体1102a的第二面1104电性连接。
所述涂覆导电胶的厚度为1~10um。最优厚度为8um，也可以为2um、4um、5um或6um。
S6、在所述导电层105上通过光学胶贴附所述偏光片111；由于此步骤中光学胶比较薄，并未在附图中标记。
S7、所述玻璃盖板108在偏光片111上通过光学胶层107贴附玻璃盖板108于所述偏光片111上，所述光学胶层107与光学胶材质皆为OCA胶。
本发明提供了一种显示面板的制备方法，通过在彩色滤光片104侧对所述偏光片111的连接层106以及偏光层109偏贴前，先进行导电胶涂布（可使用喷嘴式、油墨打印等方式进行），可以避免导电胶与所述偏光层接触。
在偏贴所述偏光片111的连接层106以及偏光层109时，可利用所述偏光片111将已涂布导电胶（即所述第二导电体1102b）与所述导电层紧密贴合。并实现所述导电块1102与偏光层109不接触，使所述导电块1102远离所述偏光层109，从而避免导电胶与偏光层109表面反应出现腐蚀偏光片111的问题。
本发明的技术范围不仅仅局限于所述说明中的内容，本领域技术人员可以在不脱离本发明技术思想的前提下，对所述实施例进行多种变形和修改，而这些变形和修改均应当属于本发明的范围内。
