Description

显示面板的制造方法及使用该方法所制造的显示面板 技术领域
本发明涉及显示技术领域，尤其涉及一种显示面板的制造方法及使用该方法所制造的显示面板。
 背景技术
现有液晶显示器，手机屏、平板等相较于传统的屏幕而言，除了在追求更高的清晰度，更高的屏占比，功耗以及显示效果等的用户体验上的需求提升外，在柔性屏及折叠屏方面，其更新颖的外形设计上也成了越来越多的客户追求的目标，而柔性屏及折叠屏除了体积轻薄以外，由于其具有可弯曲、柔韧性良好的特性，柔性屏及折叠屏备受青睐。
目前在制作折叠屏时，当折叠的曲率半径无法达到更小的范围，如显示屏的曲率半径在R5~R10时，传统的工艺模式以及偏光片（POL）材料无法实现较小曲率半径的弯折，在弯折位置除了容易出现金属断线、盒厚差异造成的显示不良外，还有一个较大问题是无法实现POL的弯折。无论是先贴POL再弯折，还是弯折后再贴POL，由于POL的材料为较脆的三醋酸纤维素（TAC），在弯折位置容易出现POL断裂及失效的问题。
因此，需要设计一种新的显示面板的制造方法及使用该方法所制造的显示面板，以克服现有技术中存在的问题。
 技术问题
针对以上现有技术存在的缺点和不足之处，本发明提供一种显示面板的制造方法及使用该方法所制造的显示面板，解决了偏光片折叠时断裂及失效的技术问题，实现了显示面板在折叠位置的曲率半径更小。

本实施例通过涂布方式制作的所述下偏光片4或所述上偏光片7的厚度远小于目前传统最薄型偏光板的厚度，并且通过涂布型的偏光片设计，既解决了不规则形状的偏光片贴附的工艺困难，也解决了偏光片在折叠时断裂及失效的技术问题，实现了显示面板100在折叠位置的曲率半径更小。
请参阅图3所示，本发明其中一实施例中提供一种显示面板100的制造方法，包括步骤：
S1、提供一基板1；所述基板1的材质包括玻璃、聚乙二醇对苯二甲酸酯或非晶型环烯烃聚合物；
S2、在所述基板1上制作所述柔性衬底层3；
S3、在所述柔性衬底层3上通过涂布宾主型聚合物液晶或宾主型聚合物液晶添加二色性色素方式制作所述下偏光片4；
S4、在所述下偏光片4上制作所述液晶层6；以及
S5、在所述液晶层6上通过涂布宾主型聚合物液晶或宾主型聚合物液晶添加二色性色素方式制作所述上偏光片7。
本实施例中，所述下偏光片4或所述上偏光片7的材质包括宾主型聚合物液晶。所述下偏光片4或所述上偏光片7的材质还包括二色性色素，即所述宾主型聚合物液晶添加所述二色性色素。
本实施例中，在所述提供一基板1步骤S1之后以及在所述制作柔性衬底层3步骤S2之前还包括：
S11、在所述基板1上制作光阻层2，所述光阻层2环绕所述基板1的边缘形成一凹槽10；其中所述光阻层2的材质包括黑色油墨或白色油墨，换句话讲，所述光阻层的颜色为黑色或白色。在所述凹槽10内依次制作所述柔性衬底层3、所述下偏光片4、所述液晶层6以及所述上偏光片7。
本实施例中，在所述制作下偏光片4步骤S4之后以及在制作液晶层6步骤S5之前还包括：
S41、在所述下偏光片4上制作所述位相差膜5。具体为通过涂布并用紫外线照射的方式制作所述位相差膜5。设置所述位相差膜5主要目的是提升偏光片的稳定性及使用寿命，用紫外线照射的作用为决定所述位相差膜5的补偿方向，所述位相差膜5补偿了液晶层6不同的波长下的相位差，提高了对比度。另外，设置所述位相差膜5可避免可靠性测试中的鼓包水纹现象，同时由于是涂布型的材料，也可避免传统堆叠材料中表面由于胶水与位相差表面附着力弱，散热能力差及支撑力弱，爆裂等相关问题。
本实施例中，所述制作柔性衬底层3步骤中，通过涂布聚酰亚胺溶液并用紫外线照射进行配向的方式制作所述柔性衬底层3。所述柔性衬底层3的厚度范围为400-800Å。
本实施例通过涂布方式制作的所述下偏光片4或所述上偏光片7的厚度远小于目前传统最薄型偏光板的厚度，并且通过涂布型的偏光片设计，既解决了不规则形状的偏光片贴附的工艺困难，也解决了偏光片在折叠时断裂及失效的技术问题，实现了显示面板100在折叠位置的曲率半径更小。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
