Flexible display device

Abstract

This invention relates to a flexible display device, comprising a curved base, multiple display modules, and multiple push-fit fastening components. The multiple display modules are disposed on the curved base. Each display module includes a flexible light panel and multiple LED elements. The flexible light panel includes a first surface and a second surface facing each other. The multiple LED elements are arranged in a matrix on the first surface. Each push-fit fastening component includes a first fastening member and a second fastening member that cooperate with each other. The first fastening member is fixed to the curved base and faces the first surface, and the second fastening member is fixed to the flexible light panel and corresponds to the position of the first fastening member on the curved base.

Claims

1. A flexible display device, comprising: a curved base; a plurality of display modules disposed on the curved base, each display module including a flexible light panel and a plurality of LED elements, the flexible light panel including a first surface and a second surface opposite to each other, the plurality of LED elements being arranged in a matrix on the first surface; and a plurality of push-in fastening assemblies, each push-in fastening assembly including a first fastening member and a second fastening member that cooperate with each other, the first fastening member being fixed to the curved base and facing the first surface, and the second fastening member being fixed to the flexible light panel and corresponding to the first fastening member's position on the curved base; wherein each LED element further includes a first signal input port, a second signal input port and a signal output port, the first signal input port of any LED element being electrically connected to the second signal input port of another LED element, and the signal output port of any LED element being electrically connected to the first signal input port of another LED element.

2. The flexible display device of claim 1, wherein the first fastening member includes a head and a neck, one end of the neck is connected to the head and the other end of the neck is connected to the curved base, and the cross-sectional diameter of the head is greater than the cross-sectional diameter of the neck; and wherein the second fastening member includes a receiving portion and an opening portion, the receiving portion communicating with the outside through the opening portion, and the cross-sectional diameter of the opening portion is smaller than the cross-sectional diameter of the head and larger than the cross-sectional diameter of the neck.

3. The flexible display device of claim 1, wherein the flexible light panel further includes a plurality of perforations, each of the perforations extending from the first surface to the second surface, and each of the perforations being disposed within a rectangular area surrounded by the centers of four adjacent LED elements.

4. The flexible display device as claimed in claim 3, wherein the transmittance of the rectangular area is greater than 50%.

5. The flexible display device of claim 1, wherein each of the LED elements includes a plurality of light sources of different colors, and the arrangement order of the plurality of light sources of any LED element is the opposite of the arrangement order of the plurality of light sources of the adjacent LED element.

6. The flexible display device of claim 1 further includes at least one auxiliary fastener, each of the auxiliary fasteners being disposed on the flexible light panel of the display module, such that the display module is assisted in being fixed to the curved base by the at least one auxiliary fastener.

7. The flexible display device as claimed in claim 6, wherein each of the auxiliary fasteners is a magnet, an adhesive, or a screw.

8. The flexible display device of claim 1, wherein each of the LED elements has a built-in driving unit, and the second surface of the flexible LED panel of each display module does not have any additional driving elements.
