Projection Device

A projection device comprising:

• a projection screen;
• a display device, having a curved display surface, wherein a curvature of the curved display surface matches a curvature of a projection surface of the projection screen;
• and
• a projection lens component set between the display device and the projection surface of the projection screen, wherein the projection lens component has an incident light surface;
• and
• wherein the curved display surface of the display device is surrounded by a part of an outer periphery of the incident light surface of the projection lens component, and the projection lens component is configured to guide a light beam emitted from the curved display surface from the part of the outer periphery surrounded by the incident light surface to another part of the outer periphery of the incident light surface, and project the light beam to the projection surface.

A projection system comprises:

• a projection device, and
• a projection screen comprising a projection surface,
• wherein the projection device comprises:
• a display device, having a curved display surface, wherein a curvature of the curved display surface matches a curvature of the projection surface;
• and
• a projection lens component, wherein an incident light surface of the projection lens component is a convex arc surface towards the curved display surface, and a light beam output by the curved display surface is projected onto the projection surface through the projection lens component.
