The present disclosure relates to a tiled electronic device, and in particular to a tiled electronic device with a narrow frame.
In recent years, display screens have been widely used to dynamically display advertisements. However, due to the size limitations of an operable display screen, it is difficult to display an advertisement over a large area using a single display screen.
In order to solve the above problem, in the prior art, a plurality of display screens are connected into one screen wall to display large-area advertisements. However, the display area of the display panel cannot cover the entire area of the display panel, and thus a frame is formed on the edge of the display panel. When the display panel is spliced, the image displayed on the screen wall will appear as a grid-like line, which affects the quality of the integral image of the screen wall.
Accordingly, while existing display panels have been generally adequate for their intended purposes, they have not been entirely satisfactory in all respects. Consequently, it would be desirable to provide a solution for improving the display panels.
A tiled electronic device includes a plurality of display panels, and at least one of the display panels includes a flexible substrate, a pixel, and two signal wires. The flexible substrate has a display portion and a bent portion connected to the display portion. The pixel is disposed on the display portion. The signal wires are disposed on the flexible substrate, and electrically connected to the pixel. Each of the signal wires has a first segment disposed on the display portion, and a second segment disposed on the bent portion. The two first sections have a first pitch, and the two second sections have a second pitch. The first pitch is different from the second pitch.
The invention can be more fully understood by reading the subsequent detailed description and examples with references made to the accompanying drawings, wherein:

The spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. Moreover, the shape, size, thickness, and tilt angle depicted in the drawings may not be drawn to scale or may be simplified for clarity of discussion; these drawings are merely intended for illustration.
In the present disclosure, the term “electrically connected to” includes, unless otherwise defined, a direct connection, an indirect connection, and an electrical coupling.
In the present disclosure, the term “substantially” means the variation of the absolute value of the distance between the two is less than 10%.

In some embodiments, the number of display panel 1 may exceed 100. The size of the display panel 1 is greater than or equal to 5 inch and less than or equal to 100 inch, but it is not limited thereto.
In the embodiment, the sizes and the shapes of the display panels 1 may be the same. In some embodiments, the sizes and/or the shapes of the display panels 1 may be different.

The connection lines, which are connected the geometric centers of the light-unit electrodes 11 and the geometric center of the common electrode 12, may form a polygonal area or an irregular area. The geometric center of the area formed by the connecting lines is defined as a pixel center.
The pixel 10 may include only one light-unit electrode 11 or only one common electrode 12. In another embodiment, if the pixel 10 includes only one light-unit electrode 11 and one common electrode 12, the connection line, which is connected the geometric center of the light-unit electrode 11 and the geometric center of the common electrode 12, has a center point. The center point is the pixel center.
The pixel 10 may not include the light-unit electrode 11 or may not include the common electrode 12. The described embodiment is only an example and is not limited thereto. The pixel 10 may include one single light-unit electrode 11 or include one single common electrode 12. The geometric center of the light-unit electrode 11 itself or the geometric center of the common electrode 12 itself is the pixel center. Moreover, in two adjacent display panels 1, the distance d12 between any two pixel centers of adjacent pixels 10 arranged in the extension direction D1 are substantially the same as the distance d11.

In some embodiments, the distances d11 and d12 are substantially different than the distances d13 and d14 respectively.
Accordingly, in the tiled electronic device A1 of the present disclosure, the pixels 10 may be filled with each display panel 1. Each display panel 1 may has a narrow frame F1.

The pixels 10 may present in different colors or brightness by controlling the voltage of the different light-unit electrodes 11 or the voltage of the common electrode 12 in the pixel 10.
In one embodiment, the material of the flexible substrate 20 may be polyimide (PI), polyethylene terephthalate (PET) or another material that is suitable for use as a flexible substrate. The described embodiment is only an example and is not limited thereto.

In some embodiments, the pixel 10 may not include the common electrodes 12, and the common electrodes 12 are disposed on the opposite side of the flexible substrate 20, so as to form a vertical type of LED structure. In addition, the light-unit electrodes 11 are arranged in an array in the pixel 10.

There may be at least one light-unit electrode 11. In some embodiments, there may be four, five, or six light-unit electrodes 11. In other embodiments, the light-unit electrodes 11 have different sizes or shapes. It depends on the requirements of the color balance of the display panel or the emission layer of LEDs use the different luminescent materials having different lifetime.
For example, if the lifetime of the blue luminescent material is less than the lifetime of the red or green luminescent material, the size of the blue light-unit electrode may be larger than the size of the red or green light-unit electrode. The described embodiment is only an example and is not limited thereto.
In one embodiment, the arrangement of the light-unit electrodes 11 and the light-emitting regions of the light-emitting diodes (LEDs), which was performed after the packaging process (not shown in figures), may be different in the top view of the display panel 1.
