Abstract

A three dimension apparatus is provided and includes a backlight source, a display panel and a fly-eye lens array. The backlight source is used for providing an emitted light, the display panel is used for displaying an image based on data signals, scan signals, and the emitted light from the backlight source. The backlight source includes a plurality of sub-pixel units. The fly-eye lens array includes a plurality of lens units for performing a convergence operation on the emitted light for the backlight source to achieve a three dimensional displaying for naked eyes. The shape of each of the lens units is a square.

First claim

What is claimed is:

1. A three dimensional display apparatus, comprising:
a backlight source for providing emitted light;
a display panel for displaying an image based upon data signals, scan signals, and the emitted light from the backlight source, the display panel including a plurality of sub-pixel units; and
a fly-eye lens array including a plurality of lens units for performing a convergence operation on the emitted light for the display panel to achieve a three dimensional displaying for naked eyes;
wherein a shape of each of the lens units is a square, the lens units are arranged in a square, the display panel includes a plurality of image units formed by at least one of the sub-pixel units, and each of the image units corresponds to one of the lens units;
wherein an angle θ between an edge of the lens units and a shorter side of the display panel is wider than 3 degrees and narrower than 7 degrees, wider than 12 degrees and narrower than 22 degrees, wider than 26 degrees and narrower than 29 degrees, or wider than 33 degrees and narrower than 40 degrees.

2. The three dimensional display apparatus as claimed in claim 1 , wherein a pitch P of the lens units is longer than 1 mm and shorter than 1.5 mm.

3. The three dimensional display apparatus as claimed in claim 1 , wherein a focal length f of the lens unit is longer than 2.2 mm and shorter than 3.5 mm.

4. The three dimensional display apparatus as claimed in claim 1 , wherein a difference g-f between a distance g from a vertex of the lens units to the display panel and the focal length f of the lens unit is greater than 0.3 mm and less than 0.7 mm.

5. A three dimensional display apparatus, comprising:
a backlight source for providing emitted light;
a display panel for displaying an image based upon data signals, scan signals and the light emitted from the backlight source, the display panel including a plurality of sub-pixel units; and
a fly-eye lens array including a plurality of lens units for performing a convergence operation on the emitted light for the display panel to achieve a three dimensional displaying for naked eyes;
wherein a shape of each of the lens units is a square, and the lens units are arranged in a square;
wherein an angle θ between an edge of the lens units and a shorter side of the display panel is wider than 3 degrees and narrower than 7 degrees, wider than 12 degrees and narrower than 22 degrees, wider than 26 degrees and narrower than 29 degrees, or wider than 33 degrees and narrower than 40 degrees.

6. The three dimensional display apparatus as claimed in claim 5 , wherein a pitch P of the lens units is longer than 1 mm and shorter than 1.5 mm.

7. The three dimensional display apparatus as claimed in claim 5 , wherein a focal length f of the lens unit is longer than 2.2 mm and shorter than 3.5 mm.

8. The three dimensional display apparatus as claimed in claim 5 , wherein a difference g-f between a distance g from a vertex of the lens units to the display panel, and the focal length f of the lens unit is greater than 0.3 mm and less than 0.7 mm.

9. The three dimensional display apparatus as claimed in claim 5 , wherein the lens units are arranged in a square.

10. The three dimensional display apparatus as claimed in claim 5 , wherein the display panel includes a plurality of image units formed by at least one of the sub-pixel units, and each of the image units corresponds to one of the lens units.
