Abstract

A multi-section visual display having an overlapping structure is disclosed, and includes a first magnifying lens, a second magnifying lens, a first display apparatus having a first display panel and a second display apparatus having a second display panel, wherein the second display apparatus is disposed between the first magnifying lens and the first display apparatus, and the second magnifying lens is aligned with the first magnifying lens in an edge-to-edge manner. While at an operation state, a first border area of the first display panel is partially overlapped with a second border area of the second display panel, thereby reducing the non-display area needing shielding by using a virtual image display from the first display panel/magnifying lens to shield a portion of the second border area, thus reducing the space required between the magnifying lenses and the first display panel.

Claims

1. A multi-section visual display having an overlapping structure, comprising:

a first magnifying lens;

a second magnifying lens, wherein the second magnifying lens is aligned with the first magnifying lens in an edge-to-edge manner;

a first display apparatus, comprising;

a first display panel disposed below the first magnifying lens and spaced from the first magnifying lens at a first spacing (A1), wherein the first display panel has a first border area; and

a second display apparatus disposed between the first magnifying lens and the first display apparatus, wherein the second display apparatus comprises;

a second display panel spaced from the second magnifying lens at a second spacing (A2), wherein the second display panel has a second border area, and the first display apparatus and the second display apparatus are arranged in a panel-moving mechanism, the panel-moving mechanism having an operation state and a storage state;

wherein, while the panel-moving mechanism is at the operation state, a portion of the second border area of the second display panel is overlapped with a portion of the first border area of the first display panel, thus forming an overlap portion, and the first magnifying lens is corresponding to the overlap portion and the remaining portion of the first display panel, and the second magnifying lens is corresponding to the remaining portion of the second display panel.

2. The multi-section visual display as claimed in claim 1, wherein the first magnifying lens and the second magnifying lens have a same focal length (F) and a same half width (W) of lens, the first spacing (A1), the second spacing (A2), a width (B1) of the first border area, a width of the second border area, a width (B3) of the overlap portion, the focal length (F) and the half width (W) of lens satisfying the following relationship:

3. The multi-section visual display as claimed in claim 2, wherein when an outer boundary of the first border area is aligned with an intersection of the first magnifying lens and the second magnifying lens, the first spacing (A1), the second spacing (A2), the width (B1) of the first border area, the width of the second border area, the width (B3) of the overlap portion, the focal length (F) and the half width (W) of lens satisfying the following relationship:

4. The multi-section visual display as claimed in claim 2, wherein when an outer boundary of the first border area is not aligned with an intersection of the first magnifying lens and the second magnifying lens, the first spacing (A1), the second spacing (A2), the width (B1) of the first border area, the width of the second border area, the width (B3) of the overlap portion, the focal length (F) and the half width (W) of lens satisfying the following relationship:

5. The multi-section visual display as claimed in claim 1, wherein the first magnifying lens has a first focal length (F1) and a first half width (W1) of lens, and the second magnifying lens has a second focal length (F2) and a second half width (W2) of lens, the first spacing (A1), the second spacing (A2), a width (B1) of the first border area, a width of the second border area, a width (B3) of the overlap portion, the first focal length (F1), the second focal length (F2), the first half width (W1) of lens and the second half width (W2) of lens satisfying the following relationship:

6. The multi-section visual display as claimed in claim 5, wherein when an outer boundary of the first border area is aligned with an intersection of the first magnifying lens and the second magnifying lens, the first spacing (A1), the second spacing (A2), the width (B1) of the first border area, the width (B3) of the overlap portion, the first focal length (F1), the second focal length (F2), the first half width (W1) of lens and the second half width (W2) of lens satisfying the following relationship:

7. The multi-section visual display as claimed in claim 5, wherein when an outer boundary of the first border area is not aligned with an intersection of the first magnifying lens and the second magnifying lens, the first spacing (A1), the second spacing (A2), the width (B1) of the first border area, the width (B3) of the overlap portion, the first focal length (F1), the second focal length (F2), the first half width (W1) of lens and the second half width (W2) of lens satisfying the following relationship:

8. The multi-section visual display as claimed in claim 1, wherein the first magnifying lens and the second magnifying lens are Fresnel lenses.

9. The multi-section visual display as claimed in claim 1, wherein the first display apparatus comprises a first backlight module disposed below the first display panel for providing light to the first display panel;

and the second display apparatus comprises a second backlight module disposed between the first display panel and the second display panel for providing light to the second display panel.

10. The multi-section visual display as claimed in claim 1, further comprising:

a circuit board and a power source disposed below the second display apparatus.

11. The multi-section visual display as claimed in claim 1, further comprising:

a circuit board and a power source disposed below the first display apparatus.

12. The multi-section visual display as claimed in claim 1, wherein the first display apparatus has a first slant side, and the second display apparatus has a second slant side, and the first slant side is laterally merged with the second slant side when the panel-moving mechanism is at the operation state.

13. The multi-section visual display as claimed in claim 1, wherein the panel-moving mechanism is a folding mechanism.

14. The multi-section visual display as claimed in claim 13, wherein the second display apparatus and the second magnifying lens are disposed above the first display apparatus and the first magnifying lens when the panel-moving mechanism is at the storage state.

15. The multi-section visual display as claimed in claim 1, wherein the panel-moving mechanism is a sliding mechanism.

16. The multi-section visual display as claimed in claim 15, wherein the second display apparatus and the second magnifying lens are received between the first display apparatus and the first magnifying lens when the panel-moving mechanism is at the storage state.
