本公开要求在2020年01月10日提交中国专利局、申请号为202010026172.1、申请名称为“一种显示面板和显示装置”的中国专利申请的优先权，其全部内容通过引用结合在本公开中。
技术领域
本公开涉及显示技术领域，特别涉及一种显示面板和显示装置。
背景技术
有机发光半导体(OLED)显示器具有自发光属性，理论上不需要像LCD显示一样使用两张线偏光片来控制光的方向。但由于OLED显示器内的阴极及TFT基板上的金属线具有较强的反射作用，从而导致OLED显示器在较强环境光下对比度下降，影响显示器的使用。因此，目前OLED显示器制程多采用一张圆偏光片来消除反射光，该圆偏光片一般采用多层膜贴合组成，厚度较大，是目前OLED显示器薄形化的一个重大阻碍。

附图说明

图2为本公开实施例提供的另一种显示面板的截面结构示意图。
具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
如图1和图2所示，本公开实施例提供的一种显示面板，包括：依次设置的OLED显示基板1、触控基板5和线偏光片3；其中，触控基板5包括触控基材层2和设置在触控基材层2上的触控电极4，触控基材层2被配置为相位延迟层，并与线偏光片3配合实现减小显示面板对环境光反射的作用。
本公开实施例提供的显示面板为OLED显示面板，其中包括触控基板5，触控基板5中触控基材层2被配置为相位延迟层，该相位延迟层与线偏光片3配合可实现圆偏光片功能，具有防反射作用，可以降低显示面板对环境光的反射率、提高显示面板对比度。并且，相对于相关技术中采用一圆偏光片防反射的方案，本公开实施例提供的显示面板，仅使用一普通线偏光片3即可，成本仅为圆偏光片的五分之一到十分之一，可以降低显示面板成本，并且因线偏光片3中没有位相差层，相对于圆偏光片厚度大大降低，因此可以有效降低OLED显示面板整体厚度，有利于OLED显示面板的薄形化。
另外，相关技术采用圆偏光片防反射的方案中，由于触控基材层本身具有一定位相差值，对圆偏光片中位相差膜具有一定干扰作用，二者位相差相消时将导致实际位相差值减小，导致红光部分吸收减弱，蓝光部分吸收增强，使得OLED显示面板发红；二者位相差相涨时将导致实际位相差值增加，从而蓝光部分吸收减弱，红光部分吸收增强，使得OLED显示面板发蓝；以上两种情况都将导致OLED显示面板反射率增加、对比度下降。相比之下，本 公开实施例中，直接采用触控基材层2与线偏光片3搭配实现圆偏光功能，不存在触控基材层2自身位相差值的干扰问题，因此使得显示面板可以具有更好的防反射效果，可得到更小的反射率、更高的对比度和更好的一体黑效果。
综上，相对于常规的OLED显示面板，本公开实施例提供的OLED显示面板，成本更低、厚度更薄、反射率更低、对比度更高，一体黑效果更好。
可选地，在本公实施例提供的一种具体的实施例中，触控基材层2的材料可以包括环烯烃共聚物(COP)、聚对苯二甲酸乙二醇酯(PET)或者聚碳酸酯(PC)中的一种或几种。

具体地，在本公实施例提供的一种具体的实施例中，1/4λ相位延迟层21的位相差轴与线偏光片3的透过轴之间的夹角可以为45度。此时，触控基材层2与线偏光片3配合可以实现精确的圆偏光效果，防反射效果最好。
示例性地，触控基材层可以是一层由环烯烃共聚物(COP)材料制备而成的1/4λ相位延迟层，或者是一层由聚对苯二甲酸乙二醇酯(PET)材料制备而成的1/4λ相位延迟层，或者是一层由聚碳酸酯(PC)材料制备而成的1/4λ相位延迟层。
可选地，如图2所示，在本公实施例提供的另一种具体的实施例中，触控基材层2可以包括两层相位延迟层，一层为1/2λ相位延迟层22，另一层为1/4λ相位延迟层23，其中，1/2λ相位延迟层22靠近线偏光片3，1/4λ相位延迟层23远离线偏光片3；具体地，1/2λ相位延迟层22的位相差轴与线偏光片3的透过轴之间的夹角可以为10度-20度；1/4λ相位延迟层23的位相差轴与线偏光片3的透过轴之间的夹角可以为70度-80度。
具体地，在本公实施例提供的一种具体的实施例中，1/2λ相位延迟层22的位相差轴与线偏光片3的透过轴之间的夹角可以为15度；1/4λ相位延迟层 23的位相差轴与线偏光片3的透过轴之间的夹角可以为75度。此时，触控基材层2与线偏光片3配合可以实现精确的圆偏光效果，防反射效果最好。
具体地，在本公实施例提供的一种具体的实施例中，1/2λ相位延迟层22和1/4λ相位延迟层23的材料可以相同。
示例性地，触控基材层2中的1/2λ相位延迟层和1/4λ相位延迟层，可以均是采用环烯烃共聚物(COP)材料制备而成，或者，可以均是采用聚对苯二甲酸乙二醇酯(PET)材料制备而成，或者，还可以均是采用聚碳酸酯(PC)材料制备而成。

示例性地，1/2λ相位延迟层采用环烯烃共聚物(COP)材料制备而成，1/4λ相位延迟层采用聚对苯二甲酸乙二醇酯(PET)材料或者聚碳酸酯(PC)材料制备而成；或者，1/4λ相位延迟层采用环烯烃共聚物(COP)材料制备而成，1/2λ相位延迟层采用聚对苯二甲酸乙二醇酯(PET)材料或者聚碳酸酯(PC)材料制备而成。
可选地，在本公实施例提供的一种具体的实施方式中，本公开各实施例中的1/4λ相位延迟层的位相差值可以为110nm-165nm，即1/4λ相位延迟层能够将波长λ在440nm-660nm范围内的光波的相位延后110nm-165nm，换句话说，该1/4λ相位延迟层能够使得可见光的相位延后1/4λ。
可选地，在本公实施例提供的一种具体的实施方式中，本公开各实施例中的1/2λ相位延迟层的位相差值可以为220nm-330nm，即1/2λ相位延迟层能够将波长λ在440nm-660nm范围内的光波的相位延后220nm-330nm，换句话说，该1/2λ相位延迟层能够使得可见光的相位延后1/2λ。
具体地，由于上述1/4λ相位延迟层和1/2λ相位延迟层均能够作用于可见光，从而与线偏光片3配合后能够很好的实现防止反射环境光的作用。
具体地，如图1和图2所示，本公开实施例提供的OLED显示面板中，OLED显示基板1、触控基板5和线偏光片3可以通过透明胶层依次粘合在一 起。
具体地，如图1和图2所示，触控基板5中的触控电极4设置在触控基材层2朝向线偏光片3的一侧。

本公开实施例提供的显示装置为OLED显示装置，相对于常规的OLED显示装置，本公开实施例提供的OLED显示装置，成本更低、厚度更薄、反射率更低、对比度更高，一体黑效果更好。
具体地，本公开实施例提供的OLED显示装置，可以为显示器、笔记本电脑、平板电脑或者智能手机等产品。
显然，本领域的技术人员可以对本公开实施例进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
