Abstract
一种显示装置,该显示装置(100;200)包括显示层(110;210)和透镜层(120;220),透镜层(120;220)设置在显示层(110;210)的出光侧,且包括至少一个光栅复合透镜单元(121;221);显示层(110;210)包括至少一个显示像素集(111;211),且显示像素集(111;211)配置为在显示过程中朝向光栅复合透镜单元(121;221)发射用于成像的光线;光栅复合透镜单元(121;221)配置为对显示像素集(111;211)进行光学成像;以及光栅复合透镜单元(121;221)还配置为偏转用于成像的光线,以使得光栅复合透镜单元(121;221)的像方中心视场方向与光栅复合透镜单元(121;221)的光轴的延伸方向交叉,以使得所述显示装置具有一个或者多个视点。该显示装置可以提升透镜层对显示层的成像质量。
