Abstract

A frameless display device includes a plurality of display units. Each of the display units includes a display panel including a display surface and a non-display surface opposite to the display surface, a frame formed on the edge of the display panel surrounding the display panel, a backlight module corresponding to the non-display surface including at least one backlight, an image elongated element corresponding to the display surface. Each of the display units further includes a light compensating module. The light compensating module is adjacent to the frame and includes at least one light panel and at least one compensating light. The light compensating module further includes a gap. The gap is defined in the light panel corresponding to the backlight.

First claim

What is claimed is:

1. A frameless display device comprising:
a plurality of display units collectively defining an array abutting one another between the a plurality of display units, each of the plurality display units comprising:
a display panel comprising a display surface and a non-display surface opposite to and facing the display surface;
a frame being formed on the edge of the display panel and surrounding the display panel;
a backlight module facing the non-display surface and comprising at least one backlight; and
an image elongation element corresponding to the display surface;
a light compensating module adjacent to the frame and comprising at least one light panel and at least one compensating light distributed on the at least one light panel, wherein the at least one compensating light emits light into a portion of the at least one light panel which transmits into the display panel adjacent to the frame, wherein the light panel is hollow rectangular and forms a gap in a center of the light panel, the at least one backlight faces the non-display surface of the display panel and emits light to the non-display surface through the gap.

2. The frameless display device of claim 1 , wherein the light panel comprises a light emitting surface, a light incident surface, a bottom surface opposite to the light emitting surface and three side surfaces perpendicular to the light incident surface, the backlight module further comprises a diffusion plate fitted closely with the non-display surface and aligned with the at least one backlight, the light emitting surface is opposite to the display surface and touches the diffusion plate, the at least one compensating light is distributed on the light incident surface equably.

3. The frameless display device of claim 2 , wherein a plurality of micro structures are formed on the bottom surface, two of the side surfaces are intersected with the light emitting surface, and another of the side surfaces is opposite to the light incident surface, three reflecting coatings are formed on the side surfaces.

4. The frameless display device of claim 2 , wherein the backlight module further comprises a printed circuit board and a plurality of first supports, the printed circuit board is fixed on the frame and corresponding to the display panel, the at least one backlight is fixed on a fitting surface of the printed circuit board equably and electrically connected to the printed circuit board, the plurality of first supports are set on the fitting surface of the printed circuit board equably to fix the diffusion plate.

5. The frameless display device of claim 4 , wherein the display panel, the frame, and the printed circuit board collectively defines a space, the at least one backlight, the diffusion plate and the plurality of first supports are fixed on the space.

6. The frameless display device of claim 4 , further comprising a plurality of second supports, wherein the plurality of second supports is fixed on the fitting surface of the printed circuit board equably, each of the plurality of second support comprises a support surface, the light panel is set on the support surface.

7. The frameless display device of claim 4 , wherein the at least one compensating light is electrically connected to the printed circuit board.

8. The frameless display device of claim 7 , wherein the image elongation element is a cover which completely covers the display surface.

9. The frameless display device of claim 1 , wherein the image elongation element comprises a tabulate midsection and a flexion surrounding the midsection, the midsection and the flexion being pellucid.

10. The frameless display device of claim 9 , wherein the image elongation element further comprises an optical amplifier structure, the optical amplifier structure is formed on an inner surface of the flexion and adjacent to the frame.

11. The frameless display device of claim 10 , wherein the optical amplifier structure comprises a plurality of micro optical lenses.

12. The frameless display device of claim 1 , wherein the gap is substantially a hollow-square-shaped and formed by a single light panel or a plurality of light panels.
