具体实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
如图1和图2所示，本申请实施例提供一种显示装置，其中，包括：
显示基板1和盖板2；
有色镜面层3，位于显示基板1与盖板2之间，有色镜面层3包括金属反射层31和选择性反射膜层32，金属反射层31位于选择性反射膜层32与显示基板1之间；
雾化层4，位于显示基板1与盖板2之间，雾化层4的雾度为20％-30％。
本发明提供的显示装置，在显示基板1与盖板2之间设有有色镜面层3，使得显示屏具有颜色，并且，在显示基板1与盖板2之间还设有雾度为20％～30％的雾化层4，进而使得显示屏具备优秀的防眩目效果，整体效果亮度柔和、颜色鲜明并且超具哑光感，具有很好的观感体验。
具体的，雾度(haze)是指透明或半透明材料的内部或表面由于光漫射造成的云雾状或混浊的外观。以漫射的光通量与透过材料的光通量之比的百分率表示，具体用标准“c”光源的一束平行光垂直照射到透明或半透明薄膜、片材、板材上，由于材料内部和表面造成散射，使部分平行光偏离入射方向，雾度即偏离入射方向大于2.5°的散射光通量Td与透过材料的光通量T2之比的百分率，是透明或半透明材料光学透明性的重要参数。雾度和透光率是两个概念。雾度大的材料可以是透光率不很低，如果用这样的材料做窗玻璃，白天房间显得很明亮，但又有隐蔽性。
经发明人实验研究分析，雾化层的雾度大于30％时，漫反射率增加，显示效果清晰度会受到影响，透光率会减少。雾化层的雾度小于20％时，漫反射率幅度不够，显示屏的金属哑光感会减少。因此，本申请实施例中雾化层的雾度值设定在一定范围内，即20％-30％。
一种具体的实施例中，雾化层的雾度为25％。
目前已邀请厂商制作出不同雾度的雾化层(雾度条件：25％，40％，50％)，进行测试。测试结果分析显示，雾度25％的显示效果较好，具备最好的防眩目效果，且亮度降低较小，显示画面较清楚，超具画质感。
一种具体的实施例中，如图1和图2所示，雾化层4位于盖板2与有色镜面层3之间。
示例性的，有色镜面层3中，选择性反射膜层31可以为至少两种材料组成的复合膜层，该至少两种材料的折射率不同。
下面，将以Lab颜色系统为例，来说明本申请实施例提供的显示装置的屏幕观感效果。
具体的，CIE L*a*b*是CIE的一个颜色系统，Lab值分别代表一种颜色的亮度、红绿色度和黄青色度。当L值越大，则表示颜色的亮度越高。a>0时，表示颜色为红色系，且a值越大表示颜色越红。当a<0时，则表示颜色属绿色系。b>0为黄色系，b<0为系b青色系。L值(亮度)，在0～100之间，0表示黑色，100表示白色；a值(红色度)，表示红绿之间的色泽，100为红色，-80为绿色；b值(黄色度)，表示黄蓝之问的色泽，100为黄色，-80为蓝色。
针对雾化层的不同雾度值范围，可做一个规则化公式计算。具体的，在有色镜面层和盖板之间加设雾化层，将使得显示装置的屏幕亮度降低，公式可以参考：L亮度降低值＝雾度值*L原有色镜面屏幕亮度值。对于颜色ab值，在加设雾化层后，根据不同金属和不同颜色波段的选择性，与加设雾化层之前相比，颜色将变得更加鲜明。
一种具体的实施例中，如图1和图2所示，有色镜面层3中，金属反射层31包括铝金属膜层；选择性反射膜层32包括SiN x/SiO 2/SiN x复合膜层。
示例性的，SiN x/SiO 2/SiN x复合膜层中，SiO 2的膜层厚度为50nm-170nm；显示装置的CIE颜色系统亮度值为60-80。
本申请实施例提供的显示装置，采用铝系有色镜面层，通过雾化层与有色镜面层的配合，使得该显示装置屏幕亮度柔软，颜色鲜明，具有明显的哑光效果，其效果具体可以参见表1中的Lab颜色数据。
表1
Figure PCTCN2021125511-appb-000001
具体的，如表1所示，常规的铝系有色镜面层屏幕往往具有很强的镜面 感(参见表中未有雾化层4的显示装置的L*a*b*数值)，本申请实施例提供的显示装置中，通过加入雾度为25％的雾化层，使得显示装置屏幕的亮度降低，颜色更加鲜明(参见表中增加雾度为25％的雾化层的显示装置的L*a*b*数值)。综上对比可知，相比于常规铝系有色屏幕的镜面感较强的效果，本申请实施例提供的显示装置的屏幕具有防眩目哑光感较强的观感，亮度柔软，颜色鲜明，视觉体验较好。
一种具体的实施例中，如图1和图2所示，有色镜面层3中，金属反射层31包括钼金属膜层；选择性反射膜层32包括SiN x/SiO 2/SiN x复合膜层。
示例性的，SiN x/SiO 2/SiN x复合膜层中，SiO 2的膜层厚度为50nm-190nm；显示装置的CIE颜色系统亮度值为30-60。
本申请实施例提供的显示装置，采用钼系有色镜面层，并且通过雾化层与该有色镜面层的配合，使得该显示装置屏幕亮度柔软，颜色鲜明，具有明显的哑光效果，其效果具体可以参见表2中的Lab颜色系统数据。
表2
Figure PCTCN2021125511-appb-000002
具体的，如表2所示，常规的钼系有色镜面层往往具有很强的金属感(参见表中未有雾化层的显示装置的L*a*b*数值)，本申请实施例提供的显示装置中，通过加入雾度为25％的雾化层，使得显示装置屏幕的亮度降低，颜色更加鲜明(参见表中增加雾度为25％的雾化层的显示装置的L*a*b*数值)。 综上对比可知，相比于常规钼系有色屏幕的金属感较强的效果，本申请实施例提供的显示装置的屏幕具有防眩目哑光感较强的观感，亮度柔软，颜色鲜明，视觉体验较好。
当然，金属反射层并不限于铝系和钼系，通过采用合适的金属层与雾化层相配合，即可以得到需求亮度和颜色鲜明的镜面反射显示装置。另外，选择性反射膜层也不限于是SiN x/SiO 2/SiN x三层复合膜层，也可以扩大为多层，例如采用五层以上光学薄膜设置，并且也不限于是SiN x、SiO 2的无机薄膜高低折射率材料，例如，高折射率材料可为选择TiO 2等其它材料。
一种具体的实施例中，如图1和图2所示，金属反射层31具有多个第一开口30，该多个第一开口30被配置为暴露显示基板1的OLED发光元件11；金属反射层31与显示基板1的像素界定层开口的交叠面积小于20％。
具体的，将金属反射层图案化，设置多个第一开口，可以增加透光率，提高显示装置的整体显示亮度。
示例性的，多个第一开口30可与OLED发光元件11一一对应，每个第一开口30暴露出与其对应的OLED发光元件11。
一种具体的实施例中，雾化层4可以具有多个第二开口(图中未示出)，多个第二开口被配置为暴露显示基板1的OLED发光元件11。
具体的，将雾化层4图案化，设置多个第二开口，可以增加透光率，提高显示装置的整体显示亮度。
示例性的，多个第二开口可与OLED发光元件11一一对应，每个第二开口暴露出与其对应的OLED发光元件11。
一种具体的实施例中，如图2所示，雾化层4包括阵列分布的多个雾化部41，多个雾化部41被配置为覆盖显示基板1的OLED发光元件11。
具体的，将雾化层图案化，设置为多个雾化部，以将OLED发光元件覆盖，一方面，可以最大程度上保障显示屏幕的哑光效果，另一方面显示光线可以从多个雾化部之间通过，从而可以增加透光率，提高显示装置的整体显示亮度。
当然，雾化层1并不限于上述图案化结构，也可以设置为整层结构(如图1中所示)。
一种具体的实施例中，如图3所示，本申请提供的显示装置，包括位于盖板2与有色镜面层(图3中未示出)之间的偏光片5，偏光片5包括至少一层支撑层(例如图3中的第一支撑层51和第二支撑层53)，至少一层支撑层中的任意一层支撑层被配置为雾化层。
示例性的，上述偏光片5为圆偏光片。
示例性的，上述至少一层支撑层包括靠近盖板2的第一支撑层51以及位于第一支撑层51远离盖板2一侧的第二支撑层53，第一支撑层51被配置为雾化层。
示例性的，第二支撑层53的雾度小于或等于1％。
例如，从盖板2至显示基板1方向上，偏光片5包括依次设置的第一支撑层51、偏光层52、第二支撑层53、第一压敏胶层54、相位延迟层55、第二压敏胶层56；其中，支撑层采用三醋酸纤维(TAC)材料，相位延迟层55采用聚乙烯醇(PVA)材料，将第一支撑层51雾化处理，作为雾化层使用。
具体的，对偏光片内部的支撑层进行雾化处理，使得支撑层雾度值增加为20％～30％，一方面可以使得显示屏具备防眩目效果，并且超具画质感；另一方面，无需额外增设雾化膜层，不会增加显示屏厚度，对显示屏的亮度影响也较小。
一种具体的实施例中，如图3所示，本申请实施例提供的显示装置，包括位于显示基板1与盖板2之间的至少一层光学胶层(例如图3中的第一光学胶层6、第一压敏胶层54和第二压敏胶层56)，该至少一层光学胶层中的任意一层光学胶层被配置为雾化层。
示例性的，上述被配置为雾化层的光学胶层可以是偏光片中的胶层，例如，如图3所示，可以是偏光片5中的第一压敏胶层54或者第二压敏胶层56。
或者，上述被配置为雾化层的光学胶层也可以显示屏中用于不同结构之间粘接的胶层，例如，如图3所示，可以是用于连接偏光片5与盖板2之间 的第一光学胶层6。
一种具体的实施例中，雾化层可以包括胶材和散射粒子；散射粒子分散在胶材中，或者散射粒子涂布在胶材面向盖板的一侧表面。
具体的，胶材单体里面掺杂散射功能的粒子，可以将部分光打散，以实现雾化效果。
示例性的，胶材为三醋酸纤维材料；散射粒子为亚克力系材料或者二氧化硅。
示例性的，散射粒子为球状，散射粒子的直径为2μm-9μm。
示例性的，雾化层中包含直径不同的至少两种散射粒子。
具体的，采用亚克力系或者二氧化硅材料制作的散射粒子分散到胶材单体中形成光学膜层，可使光学膜层中形成微米级的凹凸面，这些凹凸面可使入射光线发生折散，起到光扩散的作用。并且，由于散射粒子为球状，其功能类似于凸透镜，光线在经过这些粒子时被聚焦到一定的出射角度内，从而可以达到保证亮度的功能。此外，粒径大小不同的散射粒子也保证了光线不会从扩散膜中直射出去，从而进一步起到雾化的效果。并且通过控制散射粒子的浓度可以进行雾度控制，散射粒子越多，散射光越分散，雾度越大。
当然，本申请实施例中，雾化层并不限于上述实施例中的设置，也可以采用其他方式进行雾化处理，例如，也可以采用对光学膜层表面进行刻蚀处理以形成雾化效果，此处不再一一赘述。
另外，本申请实施例中，雾化层也可以位于盖板与有色镜面层之间，同样可以起到提升显示屏的观感体验、提升显示画质的效果。
具体的，本申请实施例提供的显示装置中，显示基板可以是LTPS-TFT AMOLED或IGZO-TFT AMOLED显示结构，或者，也可以是LCD显示面板。
具体的，本申请实施例提供的显示装置的显示屏具有颜色，具体的，其显示屏具有亮度柔软、颜色鲜明、哑光感较强的观感效果；并且，其显示屏亮度降低较小，显示画面较清楚，超具画质感，能够显著提升观看体验。
本申请实施例提供的显示装置，可以应用于显示器、手机等显示设备， 尤其适用于户外使用的柔性有色OLED穿戴显示，OLED手机屏，OLED笔记本，车载后视镜，行车记录仪，抬头显示器产品应用。
需要说明的是，本公开的一些实施例中，显示装置还可以包括其他的结构，这可以根据实际需求而定，本公开的实施例对此不作限制。另外，关于本公开实施例提供的各结构的材料和具体参数并不限于上述实施例，其基本要求可以参考上文中的描述，此处不再赘述。
显然，本领域的技术人员可以对本申请实施例进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
