请参照图5至图7，所述有机发光二极管像素层20设置在所述玻璃盖板10的底面102，且包括多个有机发光二极管像素单元21。在所述有机发光二极管像素层20上镶嵌设置有一微透镜阵列23。所述微透镜阵列23对应所述渐变折射率透镜11，且包括有多个渐变折射率微透镜230。各所述渐变折射率微透镜230的折射率从各所述渐变折射率微透镜230的中心231径向向外周缘232渐变，如图7所示。在本发明一实施例中，各所述渐变折射率微透镜230的折射率从各所述渐变折射率微透镜230的中心231径向向外周缘232逐渐递减，使各所述渐变折射率微透镜230作为一等效凸透镜；或者，在本发明一实施例中，各所述渐变折射率微透镜230的折射率从各所述渐变折射率微透镜230的中心231径向向外周缘232逐渐递增，使各所述渐变折射率微透镜230作为一等效凹透镜。在本发明一实施例中，各所述渐变折射率微透镜230的顶面235为平坦面，且各所述渐变折射率微透镜230的底面236为平坦面。
对于有机的所述有机发光二极管像素层20而言，可微透镜阵列23的各所述渐变折射率微透镜230的位置利用扩散法、光共聚法等手段以加工形成所述渐变折射率微透镜230。
所述影像传感器30设置在所述有机发光二极管像素层20的底面202，且对应所述微透镜阵列23。
在本发明一实施例中，所述玻璃盖板10、所述有机发光二极管像素层20、以及所述影像传感器30是沿一光轴100依序排列，所述渐变折射率透镜11的折射率所沿着渐变的径向方向是垂直所述光轴100，且各所述渐变折射率微透镜230的折射率所沿着渐变的径向方向是垂直所述光轴100。
