Description

显示面板、显示面板的制作方法以及显示装置 技术领域
本申请涉及显示技术领域，具体涉及一种显示面板、显示面板的制作方法以及显示装置。
 背景技术
液晶显示器(Liquid Crystal Display，LCD)具有高画质、体积小、重量轻、低电压驱动、低消耗功率及应用范围广等优点，故已广泛的应用于可携式电视、行动电话、摄录放影机、笔记型电脑、以及桌上型显示器等消费性电子或电脑产品中，成为显示器的主流。传统的液晶显示器架构主要包含外框、液晶面板、电路板与背光模组。目前，显示产品追求极致超窄边框甚至无边框，而根据现有的液晶面板内部走线需求，导致只能达到三无边框，地侧因为绑定区的存在无法实现无边框。
为了提高视觉效果，需要将面板的地测前框尽量做小，并在地侧设置金属装饰条作为前框，做到外观面平齐。但是，前框的颜色与面板颜色无法做到一致，所以视觉上存在色差，无法真正实现四边无边框。
 技术问题
本申请提供一种显示面板、显示面板的制作方法以及显示装置，可以在视觉上实现四边无边框显示面板设计。

液晶面板(liquid crystal panel)有两种形式，业界分别对其定义为Cell和Open Cell（OC），Cell是由两玻璃基板夹设液晶密封组装形成的液晶盒，外观与普通的薄片玻璃无异，Open Cell在Cell的基础上配置各类接口，以便外接信号源等，但Open Cell不包含液晶模组(LCM，liquid crystal module)中的背光、框架等元件。通常，Open Cell会通过一种柔性电路板（例如COF，Chip-on-Film，膜片上芯片封装）与电路板（例如PCB 板）连接。
为了实现液晶面板四边无边框设计，图1提供了一种示例性的阵列基板朝上的液晶显示面板1’，如图1所示，液晶显示面板1’从下之上依次包括彩膜侧偏光片2’、彩膜基板3’、液晶层4’、阵列基板5’、油墨层6’、以及阵列侧偏光片7’；阵列基板5’具有凸出于彩膜基板3’的绑定区8’，液晶显示面板1’还包括与位于绑定区8’的阵列基板5’绑定连接的柔性电路板（例如COF）9’。具体的，油墨层6’覆盖绑定区8’以及其他非显示区，阵列侧偏光片7’覆盖阵列基板5’。
虽然图1所示的液晶显示面板1’可以实现视觉上的四边无边框设计，但是，该设计需要针对性的设计Cell，即需要对传统的液晶显示面板的制程做较大的改变，导致成产成本大幅提高且不利于提高生产效率。
为了解决上述技术问题，本申请提供了一种显示面板、显示面板的制作方法、以及显示装置，在传统的液晶盒（Cell）制程之后增加遮挡结构的制程，使遮挡结构位于彩膜侧偏光片的下方，既可以实现视觉上的四周无边框设计，也可以节约成本以及提高生产效率。具体内容参考以下几个实施例的描述。
如图2所示，本申请实施例提供了一种彩膜基板朝上的OC显示面板1；显示面板1包括阵列基板2、液晶层3、彩膜基板4、柔性电路板5、遮挡结构6、第一偏光片7、以及第二偏光片8。具体的，阵列基板2包括像素电路区9和位于像素电路区9一侧的绑定区10；彩膜基板4与阵列基板2的像素电路区9相对设置；液晶层3夹设与阵列基板2和彩膜基板4之间；柔性电路板5一部分与阵列基板2的绑定区10绑定连接且另一部分弯折至阵列基板2的侧面（例如远离像素电路区9的一侧）；遮挡结构6覆盖绑定区10且至少与位于绑定区10的阵列基板2固定连接；第一偏光片7位于彩膜基板4和遮挡结构6上，且第一偏光片7的靠近绑定区10的侧面和对应的遮挡结构6的侧面齐平设置；第二偏光片8位于阵列基板2远离液晶层3一侧。
可以理解的，第一偏光片7在阵列基板2上的正投影覆盖遮挡结构6在阵列基板2上的正投影。
具体的，像素电路区9包括呈阵列分布的多个像素电路单元。绑定区10包括多个绑定端子，且多个绑定端子与多个像素电路单元电连接，用于传递电信号。
通常，显示面板的阵列基板或彩膜基板中设有遮光层（例如BM，黑色矩阵），遮光层会延伸至显示面板四边的非显示区，使得显示面板的四边外观上具有宽度较窄的黑色边框；而本申请所说的实现显示面板的四边无边框中的边框是指额外设置在显示面板四边的装饰性的框体，与阵列基板或彩膜基板中的遮光层形成的边框不同。
具体的，位于绑定区10的遮挡结构6的表面颜色与上述遮光层的颜色一致，使得显示面板1的正面四边外观无色差，保持了面板四边整体一致性。
具体的，本申请实施例中的阵列基板2、液晶层3、彩膜基板4、以及柔性电路板5形成的结构为传统的OC液晶显示面板结构；可以理解的，本申请实施例在传统的OC液晶显示面板的基础上，在第一偏光片7和位于绑定区10的柔性电路板5上设置遮挡结构6，且第一偏光片7延伸至覆盖遮挡结构6，使得遮挡结构6隐藏在第一偏光片7的下方。该设计不需要对传统的Cell制程做较大改动，降低了显示面板四边无边框设计的技术难点，又可以保证显示面板的绑定区的外观与其余三边颜色一致，实现了四边无边框设计。
具体的，遮挡结构6包括覆盖绑定区10的主体结构11，以及设置在主体结构11上的调色层12。调色层12的颜色与显示面板1的非显示区（例如四边边框区域，或四边边缘）的遮光层的颜色一致，降低了显示面板1四边边缘的色差以及外观差异，从而在视觉上实现四边无边框显示面板设计。
具体的，主体结构11的材料包括金属材料，但不限于此。
具体的，调色层12的材料包括油墨材料，例如黑色油墨；当然，在其他实施方式中，调色层12的材料还可以是金属氧化物或其他材料，此处不做限制。
在一具体实施方式中，如图2所示，主体结构11还延伸至阵列基板2的侧面并与阵列基板2的侧面平行设置；位于阵列基板2的侧面的主体结构11至少部分覆盖位于阵列基板2的侧面的柔性电路板5。可以理解的，主体结构11的纵向截面为倒L形。该设计使得主体结构11可以有效的保护柔性电路板5，防止柔性电路板5刮伤或被拉扯而损坏。
需要说明的是，本申请实施例中，上述阵列基板2的侧面是指阵列基板2在像素电路区9和绑定区10的排布方向上远离像素电路区9的一侧。
具体的，调色层12的远离像素电路区9的侧面还设有装饰涂层13；装饰涂层13可以向主体结构11的侧面部分延伸。装饰涂层13的材料包括UV固化胶或者类似的热熔胶。装饰涂层13可以进一步优化显示面板1的外观。可以理解的，调色层12裸露的三个侧面都可以设置装饰涂层13。
具体的，位于绑定区10的遮挡结构6与阵列基板2之间设有粘合层14。粘合层14的材料包括UV固化胶，但不限于此。可以理解的，粘合层14还可以延伸到位于绑定区10的遮挡结构6与柔性电路板5之间。
可以理解的，阵列基板2和彩膜基板4之间还设有胶框15，用于封住液晶层3。
具体的，柔性电路板5包括COF，但不限于此。
在一具体实施方式中，显示面板1还包括位于柔性电路板5远离阵列基板2一侧的电路板16；电路板16包括PCB 板，但不限于此。
可以理解的，本申请实施例中的柔性电路板仍采用传统的正面绑定工艺，而图1所示的液晶显示面板中的柔性电路板（COF）采用的是背面绑定工艺，背面绑定工艺不属于传统的绑定方式，需要对相关的设备进行改造，需要重新设计新的线体才能完成；并且，背面绑定工艺中电路板（PCB板）上面的元器件与柔性电路板为异面，加工难度较高。因此，本申请实施例可以采用量产设备与工艺进行绑定，有利于提高生产效率。
本实施例中，将遮挡结构6隐藏在第一偏光片7的下方，简化了四边无边框显示面板1的技术难点，使显示面板1的正面四边边缘颜色保持一致性，降低显示面板1的四边边缘色差及外观差异，有利于提高整机的画面品味；并且，本申请在传统的（主流的）OC显示面板1的制程基础上将遮挡结构6设置在第一偏光片7下方的绑定区10，一方面，相对于阵列基板朝上的四边无边框显示面板方案，本申请对显示面板的Cell制程改动小，无需针对性设计Cell，可大幅降低成本，另一方面，本申请的方案兼容性好，可适用于大部分OC显示面板制程。

步骤S301：提供对盒设置的阵列基板和彩膜基板；其中，阵列基板包括像素电路区和位于像素电路区一侧的绑定区，彩膜基板对应像素电路区设置。

在第一主体部17的表面形成调色层12；其中，调色层12和主体结构11构成遮挡结构6；

具体的，在第一主体部17的表面形成调色层12，包括以下步骤：在第一主体部17远离阵列基板2的一侧进行表面印刷（例如丝印涂层），形成调色层12；其中，调色层12的材料为油墨材料。
在其他实施方式中，还可以采用金属外观处理（例如覆膜/氧化等工艺）形成调色层12。
具体的，如图4所示，可以采用常规的正面绑定工艺将柔性电路板5绑定在阵列基板2的绑定区10。与背面绑定工艺相比，本申请可以采用量产设备与工艺绑定柔性电路板5，有利于提高生产效率以及节约成本。
具体的，柔性电路板5包括COF，但不限于此。
在一具体实施方式中，柔性电路板5远离阵列基板2一侧绑定有电路板16。具体的，电路板16包括PCB 板，但不限于此。

具体的，第一主体部17和第二主体部18呈倒L形连接，且第一主体部17和第二主体部18一体成型。第一主体部17和第二主体部18构成的主体结构11可以有效的保护柔性电路板5，防止柔性电路板5刮伤或被拉扯而损坏。
步骤S303：在彩膜基板和遮挡结构上设置第一偏光片；其中第一偏光片的靠近绑定区的侧面和对应的遮挡结构的侧面齐平设置。
可以理解的，如图7所示，第一偏光片7在阵列基板2上的正投影覆盖遮挡结构6在阵列基板2上的正投影。
