 本发明的实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域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，都属于本发明保护的范围。

请参阅图1，图1是本发明第一实施例提供的显示面板的剖面结构示意图，该显示面板10包括基板100，位于基板100上的多个子像素110、覆盖多个子像素110的封装层120和位于封装层120上的光学膜层130。该基板100包括平面区101和曲面区102，多个子像素110分布在平面区101和曲面区102，即多个子像素110包括位于平面区101的平面区子像素111和位于曲面区102的曲面区子像素112，平面区子像素111包括平面区第一子像素111G、平面区第二子像素111R和平面区第三子像素111B，曲面区子像素112包括曲面区第一子像素112G、曲面区第二子像素112R和曲面区第三子像素112B。在本实施例中，第一子像素（G）为绿色子像素，第二子像素（R）为红色子像素，第三子像素（B）为蓝色子像素，即第一子像素G）产生绿色光源，第二子像素（R）产生红色光源，第三子像素（B）产生蓝色光源。所述第一子像素（G）的面积小于所述第二子像素（R）的面积，且所述第一子像素（G）的面积小于所述第三子像素（B）的面积。
从功能的角度来说，光学膜层130包括多个聚光区和多个透射区，多个聚光区包括：对应曲面区第一子像素112G上方的第一聚光区1301；对应平面区第二子像素111R的第二聚光区1302；对应平面区第三子像素111B的第三聚光区1303。多个透射区包括：对应平面区第一子像素111G的第一透射区1304；对应曲面区第二子像素112R的第二透射区1305；以及对应曲面区第三子像素112B的第三透射区1306。
从制备方法的角度来说，光学膜层130包括位于所述封装层120上的图案层131，图案层131包括对应所述聚光区设置的凹槽，以及覆盖所述图案层131的平坦层132，平坦层132包括对应所述凹槽设置的填充结构。具体的，图案层131在第一聚光区1301具有第一凹槽1311，在第二聚光区1302具有第二凹槽1312，以及在第三聚光区1303具有第三凹槽1313。平坦层132具有填充所述第一凹槽1311的第一填充结构1321，填充所述第二凹槽1312的第二填充结构1322，以及填充所述第三凹槽1313的第三填充结构1323。在本实施例中，平坦层132的折射率大于图案层131的折射率，具体的，图案层131的折射率可以为1.3~1.6，平坦层132的折射率可以为1.5~1.9。图案层131和平坦层132都为透明材料，图案层131包括且不限于环氧系和亚克力系有机材料，以及SiO 2、SiON等无机材料，平坦层132包括且不限于掺杂ZrO 2、TiO 2纳米粒子的有机材料，金属氧烷等有机无机杂化材料。
其中，第一透射区1304、第二透射区1305和第三透射区1306的图案层131和平坦层132是平坦的，即不具有凹槽和填充结构，因此第一透射区1304、第二透射区1305和第三透射区1306对光线的汇聚效果小于第一聚光区1301、第二聚光区1302和第三聚光区1303，可以说光线在第一透射区1304、第二透射区1305和第三透射区1306基本是直接透射过去。
需要说明的是，由于第一凹槽1311、第二凹槽1312和第三凹槽1313都是倒梯形，因此第一填充结构1321、第二填充结构1322和第三凹槽1313都为倒梯形，即填充结构具有上表面和下表面。由于上表面和下表面形状相同，尺寸不同，因此下文所指“填充结构的形状”可以指上表面的形状，也可以指下表面的形状，下文所指“填充结构的尺寸”可以以下表面的尺寸为准。
在本实施例中，两种折射率不同的介质组合才能汇聚光线，所述第一聚光区1301具有所述第一填充结构1321和与所述第一填充结构1321相邻的图案层131，所述第二聚光区1302具有所述第二填充结构1322和与所述第二填充结构1322相邻的图案层131，所述第三聚光区1303具有所述第三填充结构1323和与所述第三填充结构1323相邻的所述图案层131。
请参阅图2a，图2a是本发明第一实施例提供的光汇聚原理图。以曲面区第一子像素112G为例，其发出的光经第一聚光区1301后被汇聚，具体的，入射光经过第一填充结构1321到达相邻的图案层131，由于平坦层132中第一填充结构1321的折射率大于图案层131的折射率，所以入射光可以在第一填充结构1321与图案层131的交界面发生全反射，因此光线被汇聚到小角度。
请参阅图2b，图2b是本发明第一实施例提供的标准化亮度与出光角度的折线图。横坐标为出光角度，纵坐标为标准化亮度，以图2a中曲面区第一子像素112G为例，正方形折线代表没有第一聚光区1301时出光角度与标准化亮度的关系，圆形折线代表有第一聚光区1301时出光角度与标准化亮度的关系。可以看出，加了第一聚光区1301后，大角度的出光亮度减弱，小角度的出光亮度增强，相当于第一聚光区1301对应的曲面区第一子像素112G的大角度出光亮度减弱，即减弱曲面区第一子像素112G大视角下的亮度，从而可以减少曲面区102的发绿现象。同理，对于平面区第二子像素111R和平面区第三子像素111B，由于平面区101是小视角出光，第二聚光区1302将平面区第二子像素111R发出的光汇聚到小角度，第三聚光区1303将平面区第三子像素111B汇聚到小角度，由此可以提高平面区101的红光和蓝光的亮度。
由于像素材料的原因，蓝光最弱，红光第二弱，绿光最强，因此可以通过将第二子像素的尺寸设计成最大、第三子像素的尺寸第二大，第一子像素的尺寸最小，以此来提高红光和蓝光的亮度，减小红光、蓝光和绿光之间的亮度差异。在本实施例中，在对应平面区第二子像素111R的上方设置第二聚光区1302，在对应平面区第三子像素111B的上方设置第三聚光区光1303可以进一步提高平面区第二子像素111R和平面区第三子像素111B的亮度，使其与绿光亮度差异变小。
请参阅图3，图3是本发明第一实施例提供的子像素分布的俯视示意图。每个图形代表一个子像素，空白图形表示子像素的上方没有第一填充结构或第二填充结构或第三填充结构，阴影图形表示子像素的上方存在第一填充结构或第二填充结构或第三填充结构，且阴影图形代表第一填充结构1321或第二填充结构1322或第三填充结构1323的形状和大小，每个子像素与其对应的填充结构在所述基板上的投影形状相同。所述第一子像素、第二子像素和第三子像素的形状分别可以包括四角星形、椭圆形、菱形、正方形、圆形和长棒形其中之一。在本实施例中，第三子像素的形状为大四角星，第二子像素的形状为小四角星，第一子像素的形状为椭圆形，所述第一填充结构1321与所述第一子像素的形状和大小相同，所述第二填充结构1322与所述第二子像素的形状和大小相同，所述第三填充结构1323与所述第三子像素的形状和大小相同。在一些实施例中，子像素的形状可以为其他形状，子像素的排布也可以有其他排布形式。
由于曲面区第一子像素112G上方设有第一聚光区1301，因此曲面区第一子像素112G上方存在第一填充结构1321，且在俯视图中第一填充结构1321（阴影部分）与曲面区第一子像素112G完全重合；由于曲面区第二子像素112R和曲面区第三子像素112B上方是透射区没有填充结构，因此曲面区第二子像素112R和曲面区第三子像素112B中没有阴影部分。平面区第二子像素111R和平面区第三子像素111B中有阴影图形，平面区第一子像素111G中没有阴影图形，这表示平面区第二子像素111R上方存在第二填充结构1322，平面区第三子像素111B上方存在第三填充结构1323，平面区第一子像素111G上不存在填充结构。
请参阅图4，图4是本发明第二实施例提供的子像素分布的俯视示意图。为了便于理解和说明，第二实施例中与第一实施例相同的结构使用相同的标号，且重复的结构不再进行描述。本实施例和第一实施例的区别在于，多个聚光区还包括位于所述曲面区102且分别对应所述第二子像素112R和第三子像素112B设置的第四聚光区1307和第五聚光区1308。其中，所述第四聚光区1307设置在所述第二透射区1305和所述平面区101之间，且向着靠近所述平面区101的方向（X）所述第四聚光区1307的尺寸逐渐增大；所述第五聚光区1308设置在所述第三透射区1306和所述平面区101之间，且向着靠近所述平面区101的方向（X）所述第五聚光区1308的尺寸逐渐增大；所述第一聚光区1301的尺寸向着所述平面区101的方向（X）逐渐增大。对应第一聚光区1301，曲面区102的多个第一填充结构1321（阴影图形）的尺寸沿X方向逐渐减小。例如，右边缘两列曲面区第一子像素112G上方，设置与曲面区第一子像素112G大小相同的第一填充结构1321（即阴影图形完全填满空白图形），沿X方向第一填充结构1321的尺寸越来越小，直至左边缘一列曲面区第一子像素112G不设置第一填充结构1321（尺寸为0）。第一填充结构1321的尺寸越大，对绿光的减弱效果越强；尺寸越小，对绿光的减弱效果越弱，由于越靠近曲面区102的右边缘，发绿现象越明显，因此这种渐变过渡的尺寸设计可以改善绿光的均匀性。
在本实施例中，图案层131还具有对应所述曲面区102的每个所述第二子像素的第四凹槽（即图案层131在第二透射区1305具有第四凹槽），以及对应所述曲面区102的每个所述第三子像素的第五凹槽（即图案层131在第三透射区1306具有第五凹槽）；所述平坦层132还具有填充所述第四凹槽的第四填充结构1324，以及填充所述第五凹槽的第五填充结构1325。所述第四填充结构1324对应第四聚光区1307，所述第五填充结构1325对应第五聚光区1308，因此所述第四填充结构1324的尺寸沿X逐渐增大，所述第五填充结构1325的尺寸沿X方向逐渐增大，由此可以改善曲面区102红光和蓝光的均匀性。
请参阅图5，图5是本发明第三实施例提供的子像素与填充结构的尺寸对比示意图。为了便于理解和说明，第三实施例中与第一实施例相同的结构使用相同的标号，且重复的结构不再进行描述。第三实施例与第一实施例的区别在于填充结构的形状，图3中填充结构的形状与子像素的形状相同，在本实施例中，填充结构与子像素的形状不同，即第一子像素(G)为椭圆形，第二子像素(R)和第三子像素(B)为四角星形，第一填充结构1321、第二填充结构1322和第三填充结构1323在俯视方向的形状为圆形。所述填充结构的直径大于对应所述子像素的内切圆直径且小于对应所述子像素的外切圆直径。
其中，所述第一填充结构1321的直径大于所述第一子像素(G)的内切圆直径(CD1)且小于所述第一子像素(G)的外切圆直径(CD2)，所述第二填充结构1322的直径大于所述第二子像素(R)的内切圆直径(CD3)且小于所述第二子像素(R)的外切圆直径(CD4)，所述第三填充结构1323的直径大于所述第三子像素(B)的内切圆直径(CD5)且小于所述第三子像素(B)的外切圆直径(CD6)。
请参阅图6，图6是本发明第四实施例提供的显示面板的剖面结构示意图，该显示面板20包括基板200，位于基板200上的多个子像素210、覆盖多个子像素210的封装层220和位于封装层220上的光学膜层230。该基板200包括平面区201和曲面区202，多个子像素210分布在平面区201和曲面区202，即多个子像素210包括位于平面区201的平面区子像素211和位于曲面区202的曲面区子像素212。平面区子像素211包括平面区第二子像素211R、平面区第一子像素211G和平面区第三子像素211B，曲面区子像素212包括曲面区第二子像素212R、曲面区第一子像素212G和曲面区第三子像素212B。
光学膜层230多个聚光区和多个透射区，多个聚光区包括位于曲面区202对应曲面区第一子像素212G的第一聚光区2301，位于平面区201对应平面区第二子像素212R的第二聚光区2302，以及位于平面区201对应平面区第三子像素212B上方的第三聚光区2303。多个透射区包括位于所述平面区201且对应第一子像素211G的第一透射区2304；以及位于所述曲面区202，且分别对应所述第二子像素212R和第三子像素212B的第二透射区2305和第三透射区2306。
进一步的，光学膜层230包括位于所述封装层220上的图案层231，所述图案层231包括对应所述聚光区设置的凸起，以及覆盖所述图案层231的平坦层232，具体的，所述图案层231在所述第一聚光区2301具有第一凸起2321，在所述第二聚光区2302具有第二凸起2322，以及在所述第三聚光区2303具有第三凸起2323。其中，所述平坦层232的折射率小于图案层231的折射率。也就是说，所述第一聚光区2301具有所述第一凸起2321和覆盖所述第一凸起2321的所述平坦层232，所述第二聚光区2302具有所述第二凸起2322和覆盖所述第二凸起2322的所述平坦层232，所述第三聚光区2303具有所述第三凸起2323和覆盖所述第三凸起2323的所述平坦层232。
由于平坦层232的折射率小于图案层231的折射率，第一聚光区2301、第二聚光区2302和第三聚光区2303主要是通过光的折射原理来聚光。具体的，第一聚光区2301将曲面区第一子像素212G发出的绿光汇聚到小角度，进而减弱了曲面区202大视角下的绿光亮度，减少曲面区202发绿现象。由于平面区201是小视角出光，第二聚光区2302和第三聚光区2303分别将红光和蓝光汇聚到小角度，因此提升了平面区201红光子像素和蓝光子像素的亮度。由于一般在平面区201绿光最强，提升红光和绿光的亮度能够使其与绿光亮度差异变小。
本发明实施例提供的显示面板，是一种适用于大角度曲面屏的微透镜结构（设置在第一聚光区、第二聚光区和第三聚光区）设计，在曲面区第一子像素上设置第一聚光区，以降低曲面区第一子像素大视角下的亮度，进而减少曲面区发绿现象。在平面区第二子像素和平面区第三子像素上分别设置第二聚光区和第三聚光区，以提升平面区第二子像素和平面区第三子像素的亮度，进而减小与绿光亮度的差异。
本发明实施例提供的显示面板可以应用于显示装置，该显示装置包括上述任一种显示面板，因此具有与上述显示面板相同的有益效果，在此不再赘述。
以上实施例的说明只是用于帮助理解本发明的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例的技术方案的范围。
