Abstract

A display apparatus having a rotating display panel which can generate a three dimensional image when viewed by a viewer wearing polarized glasses is disclosed. The display apparatus comprises a pedestal; a display body rotatably mounted on the pedestal; multiple light emitting arrays, each light emitting array further comprising multiple light emitting units and being equally spaced on a surface of the display body for displaying information when the display body rotates; and a polarizer provided on each of the light emitting arrays, the polarization direction of adjacent polarizers being perpendicular. In addition, the light emitting units are of different to colors whereby the display apparatus having a rotating display panel can generate a colorful image.

Claims

1. A display apparatus comprising:

a pedestal;

a display body rotatably mounted on said pedestal;

multiple light emitting arrays, each of said light emitting arrays comprising multiple light emitting units and equally spaced on a surface of said display body for displaying information when said display body rotates; and

a polarizer provided on each of said light emitting arrays, the polarization direction of adjacent polarizers being perpendicular,

wherein said polarizer provided on each odd numbered light emitting array is horizontally polarized, and said polarizer provided on each even numbered light emitting array is vertically polarized.

2. The display apparatus of claim 1, wherein each of said light emitting arrays is composed of multiple light emitting diodes of different colors.

3. The display apparatus of claim 1, wherein said display body is cylindrical, and each of said light emitting arrays is arranged axially and spaced equally on the wall of said cylindrical display body.

4. The display apparatus of claim 1, wherein said display body is a sphere, and each of said light emitting arrays intersects poles of the sphere and is equally separated longitudinally on the outside of said display body.

5. The display apparatus of claim 1, wherein said display body is a roller body, and each of said light emitting arrays originates at the axis of rotation and are equally spaced radially on a planar surface of said roller display body.
