Screen, projector, and image display device
View Patent ↗A screen includes; a plurality of layers including a diffusion layer that diffuses incident light; an elastic member that movably supports the diffusion layer with respect to an arbitrary holding part; and a driving unit that moves the diffusion layer in a direction perpendicular to an optical axis of light that is incident to the diffusion layer.
1. A screen comprising:
a diffusion layer that diffuses incident light;
an elastic member that movably supports the diffusion layer with respect to a holding part;
a driving unit that moves the diffusion layer in a direction perpendicular to an optical axis of light that is incident to the diffusion layer; and
a plurality of the elastic member, one of which being arranged between a bottom side face of the diffusion layer and the inner face of the holding part, another one of which being arranged between a right side face of the diffusion layer and the inner face of the holding part, and another one of which being arranged between a left side face of the diffusion layer and the inner face of the holding part,
wherein
the diffusion layer is rectangular and is made from plastic material;
the elastic member is arranged in a plane of the diffusion layer and at least between a top side face of the diffusion layer and an inner face of the holding part; and
the driving unit is arranged in a bottom side face of the diffusion layer.
2. The screen according to claim 1 , wherein:
at least one of the incidence face and the emission face of the diffusion layer is processed with antistatic treatment.
3. The screen according to claim 1 , wherein:
an antistatic processing agent is mixed in the diffusion layer.
4. The screen according to claim 1 , wherein:
an antistatic processing agent is applied on the diffusion layer.
5. The screen according to claim 1 , wherein:
the plurality of elastic members are each arranged near the centers of the respective faces of the diffusion layer.
6. A screen comprising:
a plurality of layers, wherein
at least one layer among the plurality of layers is the diffusion layer according to claim 1 ; and
at least one layer among the other plurality of layers is made from plastic material.
7. The screen according to claim 1 , wherein
the elastic member is arranged in at least between a central portion of each side face of the diffusion layer and a respective inner face of the holding part.
8. A screen comprising:
a diffusion layer that diffuses incident light;
an elastic member that movably supports the diffusion layer with respect to a holding part; and
a driving unit that moves the diffusion layer in a direction perpendicular to an optical axis of light that is incident to the diffusion layer,
wherein
the diffusion layer is rectangular and is made from plastic material;
the elastic member is arranged in a plane of the diffusion layer and at least between a top side face of the diffusion layer and an inner face of the holding part;
the driving unit is arranged in a bottom side face of the diffusion layer; and
the elastic member is provided to at least one pair of opposing corners.
9. The screen according to claim 8 , wherein:
at least one of the incidence face and the emission face of the diffusion layer is processed with antistatic treatment.
10. The screen according to claim 8 , wherein:
an antistatic processing agent is mixed in the diffusion layer.
11. The screen according to claim 8 , wherein:
an antistatic processing agent is applied on the diffusion layer.
12. A screen comprising:
a plurality of layers, wherein
at least one layer among the plurality of layers is the diffusion layer according to claim 8 ; and
at least one layer among the other plurality of layers is made from plastic material.
