Abstract

A display apparatus including a first display unit, a second display unit and a strip-shaped lens is provided. The first display unit has a first display area and a first edge area. The second display unit has a second display area and a second edge area. The strip-shaped lens is disposed on a boundary of the first edge area and the second edge area. The strip-shaped lens includes a light entering surface, a light emitting surface, a first stairs-shaped surface and a second stairs-shaped surface. The first stairs-shaped surface is located above a part of the first display area adjacent to the boundary, and connects the light entering surface and the light emitting surface. The second stairs-shaped surface is located above a part of the second display area adjacent to the boundary, and connects the light entering surface and the light emitting surface.

Dependent claims

A display apparatus, comprising:

a first display unit, having a first display area and a first edge area surrounding the first display area;
a second display unit, having a second display area and a second edge area surrounding the second display area, wherein the first display unit and the second display unit are arranged side by side with each other through the first edge area and the second edge area;
and
a strip-shaped lens, disposed on a boundary of the first edge area and the second edge area, and the strip-shaped lens comprising:
a light entering surface, facing the boundary and extending along the boundary, and extending from the boundary to above the first edge area and a part of the first display area adjacent to the boundary, and extending to above the second edge area and a part of the second display area adjacent to the boundary;
a light emitting surface, opposite to the light entering surface and facing away from the boundary, extending along the boundary, and extending from the boundary to above the first edge area and the part of the first display area adjacent to the boundary, and extending to above the second edge area and the part of the second display area adjacent to the boundary;
a first stairs-shaped surface, located above the part of the first display area adjacent to the boundary, and connecting the light entering surface and the light emitting surface;
and
a second stairs-shaped surface, located above the part of the second display area adjacent to the boundary, and connecting the light entering surface and the light emitting surface;
wherein the first stairs-shaped surface of the strip-shaped lens comprises a plurality of first step surfaces, wherein each of the first step surfaces is parallel to the first display area and the second display area, and the second stairs-shaped surface of the strip-shaped lens comprises a plurality of second step surfaces, wherein each of the second step surfaces is parallel to the first display area and the second display area, and
wherein at least a portion of a light beam emitted out from the first display area is directly incident into the strip-shaped lens through the first step surfaces, and at least a portion of a light beam emitted out from the second display area is directly incident into the strip-shaped lens through the second step surfaces.

A strip-shaped lens, comprising:

a light entering surface, facing a reference line and located above the reference line, containing a first notch, and extending from the first notch to two sides of the first notch, wherein the reference line is positioned outside the strip-shaped lens;
a light emitting surface, opposite to the light entering surface and facing away from the reference line, containing a center line, and extending from the center line to the two sides of the center line;
a first stairs-shaped surface, connecting the light entering surface and the light emitting surface;
and
a second stairs-shaped surface, connecting the light entering surface and the light emitting surface;
wherein all the reference line, the first notch, and the center line lie in a first reference plane and the reference line, the first notch, and the center line are parallel to one another, and the first notch lies between the reference line and the center line;
and the first reference plane and a second reference plane perpendicular to each other intersect in the reference line;
and
wherein the first stairs-shaped surface comprises a plurality of first step surfaces, wherein each of the first step surfaces is parallel to the second reference plane, and the second stairs-shaped surface comprises a plurality of second step surfaces, wherein each of the second step surfaces is parallel to the second reference plane, and
wherein the first step surfaces and the second step surfaces are facing the second reference plane.
