Description

Tiled display device

Technical Field

The invention relates to the technical field of display, in particular to a splicing display device.

Background

With the development of computer technology, it is becoming a trend to open multiple windows simultaneously on an electronic device (e.g., a computer) to reduce the time for switching pages back and forth when processing data and increase the amount of work space for multitasking. Especially in the professional field with the demand of instant audio-visual monitoring, such as the aviation industry, the bank financial industry, and the medical industry, the work efficiency can be effectively improved, and the complicated operations can be reduced.

Generally, a user can connect the external screen to a main screen of the electronic device and move a part of the opened windows to the external screen for displaying, thereby realizing simultaneous display of multiple windows. Or a mode of splicing a plurality of screens is adopted, and a screen extension display mode (extended mode) provided by the electronic device is utilized to increase the visual extension feeling. However, in any way, a gap or an empty space is formed between adjacent screens, so that the background or ambient light can be transmitted through the gap, which causes visual discontinuity and affects the operation experience of multiple windows.

Therefore, there is a need to design a new type of tiled display device to overcome the above-mentioned drawbacks.

The first display panel 101 and the second display panel 102 may be electrically connected through a wire or a data line (not shown), so as to achieve simultaneous display of multiple windows, or increase visual extension by using a screen extension mode display mode. In another embodiment, the first display panel 101 and the second display panel 102 may also be electrically isolated from each other (i.e., no data connection is made), and the images in the first screen 101a and the second screen 102a are displayed independently from each other.

Preferably, the first display panel 101 and the second display panel 102 are both liquid crystal display panels.

In one embodiment, the connecting member 103 connects the first display panel 101 and the second display panel 102 and covers the first display panel 101 and the second display panel 102.

Specifically, the connecting member 103 may be made of a flexible light-shielding material and completely covers the gap 104 between the first display panel 101 and the second display panel 102. The material of the connecting member 103 may have a reflectivity of less than 50%, preferably less than 25%. For example, the connecting member 103 may be made of foldable light-shielding textile, light-shielding plasticized film, light-shielding nonwoven fabric, non-reflective light-shielding metal sheet, or any combination thereof.

Further, the physical form of the connecting member 103 may be a piece of film or plate, a piece of fabric, cloth or non-woven fabric, which are integrally formed; or a composite structure formed by connecting/stacking a plurality of membranes or plates; or a foldable/unfoldable structure formed by connecting/pivoting a membrane or a plate and a material fabric, a cloth, a wire or other heterogeneous members made of different materials. For example, in some embodiments, the connecting member 103 may be a foldable shade formed by combining an opaque cloth, a connecting wire, and a plurality of light-shielding plates.

The third fixing element 109 and the fourth fixing element 110 may be made of the same material and have the same fixing manner as the first fixing element 105 and the second fixing element 106.

By the mask of the connecting member 103, the gap 104 between the first display panel 101 and the second display panel 102 is not exposed, so that the problem of discontinuous vision of the user caused by scattering of the background or ambient light from the gap 104 to the display sides of the first screen 101a and the second screen 102a during operation can be prevented, and the operation experience of multiple windows can be improved.

The number and the arrangement position of the first light shielding plate 107 and the second light shielding plate 108 are not limited to this. For example, referring to fig. 2, fig. 2 is a perspective view of a tiled display device 200 according to another embodiment of the invention. The tiled display device 200 is substantially similar to the tiled display device 100 shown in FIG. 1A, and the main difference is that the tiled display device 200 further includes

light shielding plates

207a and 207b protruding from the left and right edges 101d of the first display panel 101, and

light shielding plates

208a and 208b protruding from the left and right edges 102d of the second display panel 102.

In this embodiment, the

light shielding plates

207a and 207b may be fixed on the first back plate 101b of the first display panel 101 or the left and right edges 101d of the first display panel 101 by fasteners such as velcro tape, screws, or adhesive tape (not shown), respectively, and then extend from the left and right edges 101d to the display direction of the first screen 101a, respectively, and form an included angle of substantially 90 ° (but not limited thereto) with the first screen 101 a; the

light shielding plates

208a and 208b may be fixed on the second back plate 102b of the second display panel 102 or the left and right edges 102d of the second display panel 102 by fasteners such as velcro tapes, screws, or tapes (not shown), respectively, and extend from the left and right edges 102d to the display direction of the second screen 102a, respectively, and form an included angle of substantially 90 ° (but not limited thereto) with the second screen 102 a.

By the shielding of the

light shielding plates

207a, 207b, 208a and 208b, the interference of the background or the ambient light can be further prevented, and the operation comfort of the user is improved.

Referring to fig. 3, fig. 3 is a perspective view illustrating a tiled display device 300 according to another embodiment of the invention. In this embodiment, the

masks

207b and 208b may also be removed. As shown in FIG. 3, the structure of the tiled display device 300 is substantially similar to the tiled display device 200 shown in FIG. 2. The main difference between the two is that the edge of the first display panel 101 and the second display panel 102 adjacent to each other is not provided with a light shielding plate.

Specifically, in the present embodiment, the first display panel 101 is provided with the first light shielding plate 107 only at the upper edge 101c of the first display panel 101; and a light shielding plate 307 is arranged at the left side edge far away from the gap 104; without any light-shielding plate being arranged at the right side edge of the first display panel 101 adjoining the gap 104. The second display panel 102 is provided with a second light shielding plate 108 only at the upper edge 102c of the second display panel 102; and a light shielding plate 308 is arranged at the right edge far away from the gap 104; without any light shielding plate being arranged at the left side edge 102d of the second display panel 102 adjacent to the gap 104.

According to the embodiments, the present invention provides a tiled display device, which uses a connecting member to cover a gap or an open space between adjacent portions of a first display panel and a second display panel, so as to effectively solve the problem in the prior art that the operation experience of multiple windows is affected due to the discontinuous vision caused by the transmission of the background or ambient light from the gap between the adjacent portions of the first display panel and the second display panel.

The present invention has been described in relation to the above embodiments, which are only exemplary of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, it is intended that all such modifications and variations be included within the spirit and scope of this invention.
