具体实施方式
下面将结合附图，对本公开一些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。基于本公开所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在描述一些实施例时，可能使用了“电连接”和“连接”及其衍伸的表达。例如，描述一些实施例时可能使用了术语“点连接”以表明两个或两个以上部件彼此间有直接物理接触或电接触。这里所公开的实施例并不必然限制于本文内 容。
“A和/或B”，包括以下三种组合：仅A，仅B，及A和B的组合。
本文中“被配置为”的使用意味着开放和包容性的语言，其不排除适用于或被配置为执行额外任务或步骤的设备。
另外，“基于”的使用意味着开放和包容性，因为“基于”一个或多个所述条件或值的过程、步骤、计算或其他动作在实践中可以基于额外条件或超出所述的值。
如本文所使用的那样，“近似”或“大致”包括所阐述的值以及处于特定值的可接受偏差范围内的平均值，其中所述可接受偏差范围如由本领域普通技术人员考虑到正在讨论的测量以及与特定量的测量相关的误差(即，测量系统的局限性)所确定。
本文参照作为理想化示例性附图的剖视图和/或平面图描述了示例性实施方式。在附图中，为了清楚，放大了层和区域的厚度。因此，可设想到由于例如制造技术和/或公差引起的相对于附图的形状的变动。因此，示例性实施方式不应解释为局限于本文示出的区域的形状，而是包括因例如制造而引起的形状偏差。例如，示为矩形的蚀刻区域通常将具有弯曲的特征。因此，附图中所示的区域本质上是示意性的，且它们的形状并非旨在示出设备的区域的实际形状，并且并非旨在限制示例性实施方式的范围。
图1为根据一些实施例的显示面板DP的立体图。图2为根据图1所示实施例的显示面板DP沿着线A-A'的示意性截面图。如图1和图2所示，显示面板DP包括发光基板LS和颜色转换基板CS。显示面板DP包括用于显示图像的显示区DA和不显示图像的非显示区NDA，非显示区NDA围绕在显示区DA的外侧。在一些示例中，非显示区NDA可以封闭包围显示区DA，可以在至少一个方向上位于显示区DA的外侧。显示面板DP还包括用于密封发光基板LS和颜色转换基板CS的密封层SL，以及填充在发光基板LS和颜色转换基板CS之间的填充层FL。
上述显示面板DP在平面图中可以具有矩形形状，也可以具有圆形、椭圆、菱形、梯形、正方形或其他根据显示需要的形状。
上述显示面板DP可以应用于各种电子装置，例如，诸如平板计算机、智能电话、头戴式显示器、汽车导航单元、照相机、在车辆中提供的中心信息显示器(CID)、手表型电子装置或其他穿戴设备、个人数字助理(PDA)、便携式多媒体播放器(PMP)和游戏机的中小型电子装置，以及诸如电视、外部广告牌、监控器、包含显示屏幕的家用电器、个人计算机和膝上型计算机的中大 型电子装置。如上所述的电子装置可以代表用于应用显示装置1的单纯示例，并且因此本领域普通技术人员可以认识到，在不脱离本公开的精神和范围的情况下，显示面板DP也可以应用于其他电子装置。
颜色转换基板CS可以和发光基板LS相对设置。颜色转换基板CS可以包括用于转换入射光的颜色的颜色转换结构。颜色转换图案可以包括滤色器和波长转换图案中的至少一种。
密封层SL可以位于发光基板LS和颜色转换基板CS之间并且在非显示区NDA中。密封层SL可以在非显示区NDA中沿着发光基板LS和颜色转换基板CS的边缘设置，以在平面图中围绕显示区DA的外围或在显示区DA的外围周围。密封层SL可以由有机材料制成，例如由环氧基树脂制成，但不限于此。
填充层FL可以位于并填充发光基板LS和颜色转换基板CS之间、并且由密封层SL围绕的空间。填充物FL可以由能够透射光的材料制成。填充层FL可以由有机材料制成，例如，由硅基有机材料或环氧基有机材料等形成，但不限于此。在一些实施例中，填充层FL可以省略。
如图1所示，显示面板DP具有多个重复的像素单元PU。至少一个像素单元PU包括显示不同颜色的第一子像素PX1、第二子像素PX2和第三子像素PX3。每个子像素由位于发光基板LS一侧的结构和位于颜色转换基板CS一侧的结构构成。
图3示出了在图1和图2中说明的显示面板的显示区中的发光基板的平面图。如图3所示，发光区域LA1、LA2、LA3、LA4、LA5和LA6以及非发光区域NLA可以限定在发光基板LS的显示区DA中。从发光区域LA1、LA2、LA3、LA4、LA5和LA6发射到发光基板LS的外部的光可以是具有特定中心波长带的发射光。例如，发射光可以是蓝光，并且可以具有在大约440nm至大约480nm的范围内的峰值波长。
发光基板LS可以包括在显示区DA中设置在第n行R n中的发光区域LA1、LA2和LA3，以及设置在相邻的第n+1行R n+1中的发光区域LA4、LA5和LA6。在发光基板LS中，在第n行R n中，第一发光区域LA1、第二发光区域LA2和第三发光区域LA3可以沿着第一方向DR1顺序地且重复地设置；在第n+1行R n+1中，第四发光区域LA4、第五发光区域LA5和第六发光区域LA6可以沿着第一方向DR1顺序地且重复地设置。
一个重复的发光区域单元对应一个重复的像素单元，在第n行R n中，沿着第一方向DR1依次设置的第一子像素PX1的第一发光区域LA1、第二子像 素PX2的第二发光区域LA2和第三子像素PX3的第三发光区域LA3。
在一个重复的发光区域单元内，在第n行R n中，沿着第一方向DR1，第一发光区域LA1具有第一宽度WL1，第二发光区域LA2具有第二宽度WL2，第三发光区域LA3具有第三宽度WL3。其中，第一宽度WL1、第二宽度WL2和第三宽度WL3可以相同，也可以彼此不同。本公开不限于此。
在示例性实施例中，第一发光区域LA1的第一宽度WL1可以大于第二发光区域LA2的第二宽度WL2和第三发光区域LA3的第三宽度WL3。又或者例如，第二发光区域LA2的第二宽度WL2可以大于第三发光区域LA3的第三宽度WL3。因此，第一发光区域LA1的面积可以大于第二发光区域LA2的面积和第三发光区域LA3的面积，并且第二发光区域LA2的面积可以大于第三发光区域LA3的面积。
在示例性实施例中，第一发光区域LA1的第一宽度WL1、第二发光区域LA2的第二宽度WL2和第三发光区域LA3的第三宽度WL3可以基本相同。因此，第一发光区域LA1的面积、第二发光区域LA2的面积和第三发光区域LA3的面积可以基本相同。
类似的，在一个重复的发光区域单元内，在相邻的第n+1行R n+1中，第四发光区域LA4、第五发光区域LA5和第六发光区域LA6可以和第n行Rn的第一发光区域LA1、第二发光区域LA2和第三发光区域LA3具有基本相同的结构。
图4示出了在图1和图2中说明的显示面板的显示区中的颜色转换基板的平面图。如图4所示，透光区域TA1、TA2、TA3、TA4、TA5和TA6以及阻光区域BA可以限定在颜色转换基板CS的显示区DA中。在透光区域TA1、TA2、TA3、TA4、TA5和TA6，从发光基板LS发射的光可以穿过颜色转换基板CS并且可以提供到显示面板DP的外部。在阻光区域BA，从显示基板10发射的光不可以透射到显示面板DP的外部。
颜色转换基板CS可以包括在显示区DA中设置在第n行R n中的透光区域TA1、TA2和TA3，以及设置在相邻的第n+1行R n+1中的透光区域TA4、TA5和TA6。在颜色转换基板CS中，在第n行R n中，第一透光区域TA1、第二透光区域TA2和第三透光区域TA3可以沿着第一方向DR1顺序地且重复地设置；在第n+1行R n+1中，第四透光区域TA4、第五透光区域TA5和第六透光区域TA6可以沿着第一方向DR1顺序地且重复地设置。
第一透光区域TA1可以对应于第一发光区域LA1并与第一发光区域LA1重叠或面对第一发光区域LA1，形成第一子像素PX1的光线通道。类似地， 第二透光区域TA2可以对应于第二发光区域LA2并与第二发光区域LA2重叠或面对第二发光区域LA2，形成第二子像素PX2的光线通道。并且，第三透光区域TA3可以对应于第三发光区域LA3并与第三发光区域LA3重叠或面对第三发光区域LA3，形成第三子像素PX3的光线通道。类似的，第四透光区域TA4、第五透光区域TA5和第六透光区域TA6可以分别与第四发光区域LA4、第五发光区域LA5和第六发光区域LA6重叠或面对。
从发光基板LS提供的发射光可以在穿过第一透光区域TA1、第二透光区域TA2和第三透光区域TA3之后提供到显示面板DP的外部。在从第一透光区域TA1发射到显示面板DP的外部的光可以称为第一出射光。从第二透光区域TA2发射到显示面板DP的外部的光可以称为第二出射光。从第三透光区域TA3发射到显示面板DP的外部的光可以称为第三出射光。第一出射光可以是第一颜色的光，第二出射光可以是不同于第一颜色的第二颜色的光，并且第三出射光可以是不同于第一颜色和第二颜色的第三颜色的光。如上所述，第一颜色的光可以是具有在大约610nm至大约650nm的范围内的峰值波长的红光，并且第二颜色的光可以是具有在大约510nm至大约550nm的范围内的峰值波长的绿光。第三颜色的光可以是具有在大约440nm至大约480nm的范围内的峰值波长的蓝光。
在一个重复的透光区域单元内，在第n行R n中，沿着第一方向DR1，第一透光区域TA1可以具有第一宽度WT1，第二透光区域TA2可以具有第二宽度WT2，第三透光区域TA3可以具有三宽度WT3。其中，第一透光区域TA1的第一宽度WT1、第二透光区域TA2的第二宽度WT2和第三透光区域TA3的第三宽度WT3可以相同，也可以彼此不同。本公开不限于此。
在示例性实施例中，第一透光区域TA1的第一宽度WT1可以大于第二透光区域TA2的第二宽度WT2和第三透光区域TA3的第三宽度WT3。又或者例如，第二透光区域TA2的第二宽度WT2可以大于第三透光区域TA3的第三宽度WT3。因此，第一透光区域TA1的面积可以大于第二透光区域TA2的面积和第三透光区域TA3的面积，并且第二透光区域TA2的面积可以大于第三透光区域TA3的面积。在示例性实施例中，第一透光区域TA1的第一宽度WT1、第二透光区域TA2的第二宽度WT2和第三透光区域TA3的第三宽度WT3可以基本相同。因此，第一透光区域TA1的面积、第二透光区域TA2的面积和第三透光区域TA3的面积可以基本相同。
在颜色转换基板CS中，阻光区域BA可以位于显示区DA中的透光区域TA1、TA2、TA3、TA4、TA5和TA6周围。
本公开发明人经研究发现：如图5所示，蓝光OLED发出的蓝光由于微腔效应，其亮度随角度变化下降明显；而由于红色量子点膜和绿色量子点膜具有全角度发光的特性且不存在微腔效应，亮度随角度变化不明显。这样，随着视角的变化蓝光亮度迅速下降，而红光和绿光无明显变化，这就会导致在大视角下白光色偏严重。
图6示出了本公开实施例中显示面板DP沿图3和图4中线A1-A1'示意性截面图。本公开的一些实施例提供一种显示面板DP，包括多个发光器件LD。发光器件LD可以为有机发光二极管(Organic Light-Emitting Diode，简称OLED)、量子点发光二极管(Quantum Dot Light Emitting Diodes，简称QLED)和微型发光二极管(Mini/Micro Light Emitting Diodes，简称MLED)中的至少一种。本公开的示例性实施例中以发光器件LD为OLED进行说明，但应当认为并不限于QD-OLED显示面板。OLED发光器件具有厚度薄、响应速度快、驱动电压低、工作温度范围广、自发光、低能耗以及可制备柔性器件等优点。
如图6所示，显示面板DP可以包括发光基板LS和颜色转换基板CS，并且可以还包括填充在发光基板LS和颜色转换基板CS之间的填充层FL。

图18示出了本公开另一实施例中显示面板DP沿图3和图4中线A1-A1'示意性截面图。如图18所示，光调节层LCL具有叠层结构，包括第一光调节层LCL1和第二光调节层LCL2，第一光调节层LCL1位于第二衬底基板SUB2一侧，第二光调节层LCL2位于第一光调节层LCL1远离第二衬底基板SUB2的一侧。第一光调节层LCL1中包括第一粒子P1，第二光调节层LCL2中包括第二粒子P2。其中，第一光调节层LCL1和第二光调节层LCL具有岛状的图形，第一光调节层LCL1仅位于第三透光区域TA3，第二光调节层LCL2位于覆盖第一透光区域TA1、第二透光区域TA2和第三透光区域TA3。位于 阻光区域BA中的第二遮光图案BM2的厚度，可以和位于第三透光区域TA3中的第一光调节层LCL1与第二光调节层LCL2的厚度之和大致相等，并且和位于第一透光区域TA1与第二透光区域TA2中的第二光调节层LC2的厚度大致相等，以便提供平坦的表面进行后续工艺。
第二光调节层LCL2包括多个分离的第一图案PL1、第二图案PL2和第三图案PL3。第一图案PL1、第二图案PL2和第三图案PL3均可以包括第二粒子P2。第一图案PL1位于第一透光区域TA1，第二图案PL2位于第二透光区域TA2，第三图案PL3位于第三透光区域TA3。第二遮光图案BM2沿着垂直于显示面板DP方向上的厚度，与第一图案PL1和/或第二图案PL2沿着垂直于显示面板DP方向上的厚度大致相等，与第三图案PL3和第一光调节层LCL1沿着垂直于显示面板DP方向上的厚度之和大致相等。第一图案PL1、第二图案PL2和第三图案PL3中第二粒子P2的掺杂的质量分数不同。通过调节第二粒子P2的掺杂浓度，可以调节颜色转换层CCL的出光侧的透明材料的整体折射率，提高出光效率。
图19为图18所示的实施例中显示面板DP的另一种结构变化示意。如图19所示，第一光调节层LCL1仅位于第三透光区域TA3，第二光调节层LCL2具有连续的膜层结构，并覆盖第一透光区域TA1、第二透光区域TA2、第三透光区域TA3以及阻光区域BA。第二遮光图案BM2的厚度，可以和第一光调节层LCL1的厚度大致相等，并且小于位于第一透光区域TA1与第二透光区域TA2中的第二光调节层LCL2的厚度。
图20示出了本公开又一实施例中显示面板DP沿图3和图4中线A1-A1'示意性截面图。如图20所示，光调节层LCL和滤色层CF同层设置。光调节层LCL具有叠层结构，包括第一光调节层LCL1和第二光调节层LCL2，第一光调节层LCL1位于第二衬底基板SUB2一侧，第二光调节层LCL2位于第一光调节层LCL1远离第二衬底基板SUB2的一侧。第一光调节层LCL1中包括第一粒子P1，第二光调节层LCL2中包括第二粒子P2。其中，光调节层LCL位于第三透光区域TA3。由于第二粒子P2具有中空结构，当显示面板用于触控时，第一光调节层LCL1作为缓冲可以避免按压使得中空结构破裂。
图21示为图20所示的实施例中显示面板DP的另一种结构变化示意。如图21所示，第一光调节层LCL1和第二光调节层LCL2的位置可以进行调换，本公开内容不限于此。
图22示为图20所示的实施例中显示面板DP的又一种结构变化示意。如图22所示，光调节层LCL具有单层的结构，包括第一粒子P1和第二粒子P2 的混合物。第一粒子P1和第二粒子P2均匀混合在基质MR中。光调节层LCL的厚度和第一滤色器CF1和第二滤色器CF2的厚度大致相等，以便提供平坦的表面进行后续工艺。
在一些实施例中，光调节层LCL直接设置于第二衬底基板SUB2上。换句话说，光调节层LCL与第二衬底基板SUB2直接接触。
图23示出了图6所示的实施例中显示面板DP的再一种结构变化示意。显示面板DP中不同的发光器件LD射出不同颜色的光线。第一发光器件LD1的发射光谱、第二发光器件LD2的发射光谱和第三发光器件LD3的发射光谱互不相同。第一发光器件LD1射出第一光线L1，第二发光器件LD2射出第二光线L2，第三发光器件LD3射出第三光线L3。在一些实施例中，第一光线L1、第二光线L2和第三光线L3可以是相同的光线，即峰值波长大致相同的三种光线。例如，第一光线L1、第二光线L2和第三光线L3为相同颜色的蓝光。在另一些实施例中，第一光线L1、第二光线L2和第三光线L3可以是不同的光线，即第一光线L1的峰值波长的范围、第二光线L2的峰值波长的范围和第三光线L3的峰值波长的范围互不相同。例如，第一光线L1为红光，第二光线L2为绿光，第三光线L3为蓝光。
另外，第一光线L1、第二光线L2和第三光线L3还可以是峰值波长互不相同，且均在同一峰值波长范围内的三种光线。在一些示例中，第一光线L1为一种颜色的蓝光，第二光线L2为另一种颜色的蓝光，第三光线L3为与上述两种蓝光颜色不同的蓝光。
上述发光器件LD中影响发光光线L不同的因素，包括但不限于发光层OL的制作材料不同、发光层OL中发光成分的质量分数不同、或者其他能够影响第一发光材料层EML1的发射光谱的其他因素，此处不作限定。
示例性地，第一发光器件LD1的发射峰的波长为450nm～459nm，例如：450nm、453nm、455.2nm、457.3nm、458.8nm或459nm。第二发光器件LD2的发射峰的波长为460nm～469nm，例如：460nm、463nm、465.2nm、467.3nm、468.8nm或469nm。第三发光器件LD3的发射峰的波长为470nm～479nm，例如：470nm、473nm、475.2nm、477.3nm、478.8nm或479nm。
当然，也可以第一发光器件LD1的发射峰的波长大于第二发光器件LD2的发射峰的波长，或者第一发光器件LD1的发射峰的波长大于第三发光器件LD3的发射峰的波长，等多种情况。以上只是举例进行说明，不应以此为限。
再参阅图23，第一颜色转换图案CCP1和第二颜色转换图案CCP2由于内部颜色转换材料QD不同，具有不同的光线吸收特性，具体可以表现为对 于不同峰值波长的光线转换或移动到另一特定峰值波长来发光的效率不同。在一些示例中，第一颜色转换图案CCP1对于第一光线L1转换或移动到另一特定峰值波长来发光的效率，高于第一颜色转换图案CCP1对于第二光线L2转换或移动到另一特定峰值波长来发光的效率和第一颜色转换图案CCP1对于第三光线L3转换或移动到另一特定峰值波长来发光的效率。类似的，第二颜色转换图案CCP2对于第二光线L2转换或移动到另一特定峰值波长来发光的效率，高于第二颜色转换图案CCP2对于第一光线L1转换或移动到另一特定峰值波长来发光的效率和第二颜色转换图案CCP2对于第三光线L3转换或移动到另一特定峰值波长来发光的效率。
同样的，颜色转换图案CCP和透光图案TP由于内部颜色转换材料QD的有无，具有不同的光线透射特性，具体可以表现为对于不同峰值波长的光线透过透光图案TP的效率不同。在一些示例中，透光图案TP对于第三光线L3透过透光图案TP的效率，高于透光图案TP对于第二光线L2透过透光图案TP的效率和透光图案TP对于第一光线L1透过透光图案TP的效率。
从而实现，第一颜色转换图案CCP1的吸收光谱和第一发光器件LD1的发射光谱匹配，第二颜色转换图案CCP2的吸收光谱和第二发光器件LD2的发射光谱匹配，从而提高颜色转换层CCL的光线转换率，改善显示面板的色特征。
如图23所示，通过将第一透光区域TA1对应于第一发光区域LA1并与第一发光区域LA1重叠或面对第一发光区域LA1，第二透光区域TA2对应于第二发光区域LA2并与第二发光区域LA2重叠或面对第二发光区域LA2，第三透光区域TA3对应于第三发光区域LA3并与第三发光区域LA3重叠或面对第三发光区域LA3设置；可以使第一颜色转换图案CCP1对第一光线L1的峰值波长转换或移动到另一特定峰值波长来发光，第二颜色转换图案CCP2对第二光线L2的峰值波长转换或移动到另一特定峰值波长来发光，透光图案TP透过第三光线L3。提高第一颜色转换图案CCP1和第二颜色转换图案CCP2对光线L的转换效率，同时提高透光图案TP的透光效率，进而提高显示面板DP的出光效率。
图24示为图6所示实施例中显示面板DP中相邻两个重复单元的一种结构变化示意。第一重复单元RU1和第二重复单元RU2相邻设置，每个重复单元RU均包括第一透光区域TA1、第二透光区域TA2和第三透光区域TA3。如图24所示，第一重复单元RU1中的第三透光区域TA3和第二重复单元RU2中的第三透光区域TA3相邻设置。在一些实施例中，在相邻的两个第三透光 区域TA3之间取消第一遮光图案BM1，沿着第一方向DR1，位于第一重复单元RU1中的第三透光区域TA3和第二重复单元RU2中的第三透光区域TA3中的相同颜色的第三滤色器CF3可以具有连续的膜层。

图26为图6所示实施例中显示面板DP中相邻两个重复单元的另一种结构变化示意。第一重复单元RU1和第二重复单元RU2相邻设置，每个重复单元RU均包括第一透光区域TA1、第二透光区域TA2和第三透光区域TA3。如图26所示，第一重复单元RU1中的第一透光区域TA1和第二重复单元RU2中的第一透光区域TA1相邻设置。在一些实施例中，在相邻的两个第一透光区域TA1之间取消分隔壁PW，沿着第一方向DR1，位于第一重复单元RU1中的第一透光区域TA1和第二重复单元RU2中的第一透光区域TA1中的相同颜色的第一颜色转换图案CCP1可以具有连续的膜层。
类似的，在第一重复单元RU1中的第二透光区域TA2和第二重复单元RU2中的第二透光区域TA2相邻设置。在一些实施例中，在相邻的两个第二 透光区域TA2之间取消分隔壁PW，沿着第一方向DR1，位于第一重复单元RU1中的第二透光区域TA2和第二重复单元RU2中的第二透光区域TA2中的相同颜色的第二颜色转换图案CCP2可以具有连续的膜层。
图27为图6所示实施例中显示面板DP中相邻两个重复单元的另一种结构变化示意。第一重复单元RU1和第二重复单元RU2相邻设置，每个重复单元RU均包括第一透光区域TA1、第二透光区域TA2和第三透光区域TA3。如图27所示，第一重复单元RU1中的第三透光区域TA3和第二重复单元RU2中的第三透光区域TA3相邻设置。在一些实施例中，在相邻的两个第三透光区域TA3之间取消第一遮光图案BM1，沿着第一方向DR1，位于第一重复单元RU1中的第三透光区域TA3和第二重复单元RU2中的第三透光区域TA3中的相同颜色的第三滤色器CF3可以具有连续的膜层；并且，在相邻的两个第三透光区域TA3之间取消分隔壁PW，沿着第一方向DR1，位于第一重复单元RU1中的第三透光区域TA3和第二重复单元RU2中的第三透光区域TA3中的相同颜色的透光图案TP可以具有连续的膜层。
图28为图6所示实施例中显示面板DP中相邻两个重复单元的另一种结构变化示意。第一重复单元RU1和第二重复单元RU2相邻设置，每个重复单元RU均包括第一透光区域TA1、第二透光区域TA2和第三透光区域TA3。如图28所示，第一重复单元RU1中的第一透光区域TA1和第二重复单元RU2中的第一透光区域TA1相邻设置。在一些实施例中，在相邻的两个第一透光区域TA1之间取消第一遮光图案BM1，沿着第一方向DR1，位于第一重复单元RU1中的第一透光区域TA1和第二重复单元RU2中的第一透光区域TA1中的相同颜色的第一滤色器CF1可以具有连续的膜层；并且，在相邻的两个第一透光区域TA1之间取消分隔壁PW，沿着第一方向DR1，位于第一重复单元RU1中的第一透光区域TA1和第二重复单元RU2中的第一透光区域TA1中的相同颜色的第一颜色转换图案CCP1可以具有连续的膜层。

如图30所示，图30中横坐标表示蓝光的波长，纵坐标表示量子点亮度转化率。从图30中可以看出在蓝光发射光谱的发射峰不同的情况下，红色量子点RQD和绿色量子点GQD的亮度转化率不同。随着蓝光OLED器件发射峰(EL Peak)值增大，RQD、GQD的亮度转换率随之增加。由此可见蓝光OLED器件的蓝光发射光谱的发射峰将会显著影响量子点的亮度转换率。图25中可以看出蓝光的波长从454nm提升至463nm的过程中，红色量子点膜RQD的亮度转换率提升了14.4％，绿色量子点膜GQD的亮度转换率提升了15.8％。不同的量子点膜实际会有不同的最佳激发蓝光波长。
