Abstract

A seamless splicing multi-panel display device includes a plurality of first liquid crystal panels being spaced apart, at least one second liquid crystal panel between every two the first liquid crystal panels, and a backlight module opposite to the first liquid crystal panel and the second liquid crystal panel. The first liquid crystal panel includes a first display portion and first non-display portions extending from edges of the first display portion. The second liquid crystal panel includes a second display portion and second non-display portions extending from edges of the second display portion. The second non-display portion is fixed on an area between the first display portion and the first non-display portion. In this way, the multi-panel display device realizes the seamless splicing display so as to enhance the display performance.

First claim

What is claimed is:

1 . A multi-panel display device for realizing seamless splicing, comprising:
a plurality of first liquid crystal panels being spaced apart, at least one second liquid crystal panel between every two the first liquid crystal panels, and a backlight module opposite to the first liquid crystal panel and the second liquid crystal panel; the first liquid crystal panel comprises a first display portion and first non-display portions extending from edges of the first display portion, and the second liquid crystal panel comprises a second display portion and second non-display portions extending from edges of the second display portion; and the second non-display portion is fixed on an area between the first display portion and the first non-display portion, and the first non-display portion is fixed below the area between the second display portion and the second non-display portion.

2 . The multi-panel display device as claimed in claim 1 , wherein a line between the second display portion and the respective non-display portion aligns with the line between the non-display portion and the first display portion.

3 . The multi-panel display device as claimed in claim 1 , wherein the second non-display portion is adhered on the area between the first display portion and the first non-display portion, and the first non-display portion is adhered to a down surface of the area between the second display portion and the second non-display portion.

4 . The multi-panel display device as claimed in claim 3 , wherein a down polarizer of the second liquid crystal panel extends until an edge of the first liquid crystal panel below the second liquid crystal panel, and an up polarizer of the first liquid crystal panel extends until the edge of the second liquid crystal panel above the first liquid crystal panel.

5 . The multi-panel display device as claimed in claim 1 , wherein the backlight module comprises:
a back frame comprising a bottom plate and side plates at two lateral sides of the bottom plate, and the side plate supports the first liquid crystal panel and the second liquid crystal panel; a plurality of light sources facing toward each of the first liquid crystal panels; and a plurality of light sources facing toward each of the second liquid crystal panels.

6 . The multi-panel display device as claimed in claim 5 , wherein the backlight module further comprises at least one transparent supporting pillar arranged below an overlapped portion of the first liquid crystal panel and the adjacent second liquid crystal panel, and the transparent supporting pillar supports the first liquid crystal panel and the second liquid crystal panel.

7 . The multi-panel display device as claimed in claim 6 , wherein each of the transparent supporting pillars comprises a first sub-transparent supporting pillar and a second sub-transparent supporting pillars, wherein the first sub-transparent supporting pillar is arranged between the corresponding first liquid crystal panel and the bottom plate to support the corresponding first liquid crystal panel, and the second sub-transparent supporting pillar is arranged between the corresponding second liquid crystal panel and the bottom plate to support the corresponding second liquid crystal panel.

8 . The multi-panel display device as claimed in claim 7 , wherein the backlight module further comprises a first light beam enhanced component arranged between the first liquid crystal panel, the corresponding side plate, and the first sub-transparent supporting pillar, and a second light beam enhanced component arranged between the second liquid crystal panel, the corresponding second side plate, and the second sub-transparent supporting pillars, wherein the first light beam enhanced component is configured for enhancing quality of light beams radiating the first liquid crystal panel, and the second light beam enhanced component is configured for enhancing quality of light beams radiating the second liquid crystal panel.

9 . The multi-panel display device as claimed in claim 8 , wherein the first light beam enhanced component comprises a first diffusion plate and a plurality of optical film above the first diffusion plate, and the first diffusion plate is arranged above the corresponding side plate and the first sub-transparent supporting pillar.

10 . The multi-panel display device as claimed in claim 8 , wherein the second light beam enhanced component comprises a second diffusion plate and a plurality of optical film above the second diffusion plate, and the second diffusion plate is arranged above the corresponding side plate and the second sub-transparent supporting pillar, and the second diffusion plate and the optical films above the second diffusion plate extend into the edge of the first liquid crystal panel below the second liquid crystal panel.
