Description

Technical Field

[0001] The present invention relates to the technical field of display screens, and in particular to a bendable light-emitting semiconductor display screen. Background Art

[0002] In the field of light-emitting semiconductor display screens, due to the restrictions on installation conditions and the requirements for display effects, curved and bendable light-emitting semiconductor display screens are increasingly being used in daily production and life. In response, various curved display screens have emerged.

[0003] Most of the existing curved display screens can be divided into two categories. One category, for example, is a flexible screen with application number CN201410494016.2 and publication date January 28, 2015, which uses a flexible substrate to achieve a bendable effect. However, due to the high cost of the flexible substrate, the production cost of this type of display screen is relatively high. In addition, since the flexible substrate is a continuous curved surface when bent, the welding points between the light-emitting body on the substrate and the substrate are easily damaged and broken due to bending, causing the light-emitting body to fall off. The other category, for example, is a flexible LED display screen with application number CN201320619242.X and publication date April 16, 2014, which is a rigid substrate connected by a number of connection structures and can rotate relatively to achieve the overall bendability of the screen. However, the connection structure of the existing curved display screens of this type is often relatively complex, which will block the screen, resulting in a decrease in screen utilization and is difficult to fold and bend at a large angle.

[0004] In summary, the existing curved display screen structure needs to be improved to overcome the problem that the light-emitting body is easy to fall off and block the screen. Summary of the invention

[0042] First embodiment

[0043] The present invention provides a bendable light-emitting semiconductor display screen, such as Figure 1 As shown, it includes a light board group 100 formed by a plurality of light boards 110 arranged side by side, and also includes wires 200 and a wire fixing structure 300. The wires 200 and the wire fixing structure 300 connect the plurality of light boards 110 into the light board group 100. The wires 200 pass through the wire fixing structure 300 and cross over each light board 110 to connect the plurality of light boards 110 in series to form a display screen as a whole, and allow two adjacent light boards 110 in the display screen to rotate relative to each other. For the display screen as a whole provided by the present invention, the functions of curved display (approximate curved surface) and folding of the screen can be realized.

[0044] Specifically, the wire 200 includes a first connecting wire 210 and a second connecting wire 220, both of which pass through the wire fixing structure 300 and cross over each lamp board 110 to join the plurality of lamp boards 110 together, and the first connecting wire 210 and the second connecting wire 220 cross over each lamp board 110 in opposite ways to clamp each lamp board 110, wherein the opposite means that the positions of the first connecting wire 210 and the second connecting wire 220 relative to the lamp board 110 are opposite, and a certain section of the first connecting wire 210 and a corresponding section of the second connecting wire 220 are located on opposite sides of each lamp board 110, for example, when a certain section of the first connecting wire 210 is located on one side of the lamp board 110, a corresponding section of the second connecting wire 220 is located on the other side of the lamp board 110, and for example, the first connecting wire 210 and the corresponding second connecting wire 220 pass through the wire fixing structure 300 in opposite directions each time, such as Figure 2 As shown, the first connecting wire 210 and the second connecting wire 220 form a braided structure to clamp the light panel assembly 100. Preferably, as Figure 1 and Figure 3 As shown, the light board group 100 is distributed along a direction perpendicular to the arrangement direction of the light boards 110.

[0045] There are at least two groups of first connecting wires 210, second connecting wires 220 and corresponding wire fixing structures 300 to form a connection for each light board 110, so that the relative position relationship between the light boards 110 in the display screen is more stable, and each light board 110 has a wiring flexible board 400 on the upper side for electrically connecting to an external circuit. Preferably, the wiring flexible boards 400 of all the light boards 110 form a strip-shaped wiring flexible board and the wiring flexible board is connected to the light board 110 together with the wire 200.

[0046] Preferably, in some embodiments, Figure 3 The wire 200 shown also includes a plurality of third connecting wires 230, which are located between two adjacent light panels 110 and extend in a direction perpendicular to the arrangement of the light panels. The third connecting wires 230 cross the wires 200 and are wrapped around and bundled with each group of wires 200 to connect the first connecting wires 210 and the second connecting wires 220 therein. A plurality of third connecting wires 230 and a plurality of groups of first connecting wires 210 and second connecting wires 220 are connected to form a mesh structure, thereby improving the stability of the display screen connection structure.

[0047] Specifically, Figure 1 As shown, a plurality of lamp boards 110 include adjacent first lamp boards 111 and second lamp boards 112, with a gap 120 between the first lamp board 111 and the second lamp board 112, wherein the first lamp board 111 has a first light emitting surface 111a, a first backlight surface 111b opposite to the first light emitting surface 111a, and a plurality of first lamp beads 111c arranged on the first light emitting surface 111a in a matrix distribution, the second lamp board 112 has a second light emitting surface 112a, a second backlight surface 112b opposite to the second light emitting surface 112a, and a plurality of second lamp beads 112c arranged on the second light emitting surface 112a in a matrix distribution, and the first light emitting surface 111a and the second light emitting surface 112a are both facing the same side of the lamp board group 110, that is, the side where the display screen emits light, and the first light emitting surface 111a and the second light emitting surface 112a both have a connection for electrically connecting the first lamp beads 111c and a conductive circuit pattern of the second lamp bead 112c (not shown).

[0048] Specifically, regarding the connection between the wire 200 and the wire fixing structure 300 and the connection across each lamp board 110, in this embodiment, as shown in FIG. Figure 2As shown, the first connecting line 210 has a first connecting section 211, a second connecting section 212 and a first transition section 213. The first connecting section 211 is located on the first light-emitting surface 111a, the second connecting section 212 is located on the second backlight surface 112b, the first transition section 213 passes through the gap 120, and the first connecting section 211, the first transition section 213 and the second connecting section 212 are connected in sequence. The second connecting line 220 has a first corresponding connecting section 221 corresponding to the first connecting section 211, a second corresponding connecting section 222 corresponding to the second connecting section 212 and a first corresponding transition section 223 corresponding to the first transition section 213. The first corresponding connecting section 221 is located on the first backlight surface 111b, the second corresponding connecting section 222 is located on the second light-emitting surface 112a, the first corresponding transition section 223 passes through the gap 120, and the first corresponding connecting section 221, the first corresponding transition section 223 and the second corresponding connecting section 222 are connected in sequence. The first transition section 213 and the first corresponding transition section 223 intersect in the gap 120 .

[0049] It should be understood that in the present invention, the wire 200 is located on the surface of the light board 110, which means that the wire is parallel to the surface of the light board when straightened, and the wire is restricted from moving away from the surface of the light board. In actual situations, depending on factors such as the wire fixing structure used and the wire diameter, the wire 200 and the surface of the light board 110 may be in contact or out of contact.

[0050] In addition, it should be understood that the light board group in the embodiment of the present invention is formed by connecting several light boards. In the embodiment, only the connection method of the first light board and the second light board is used as an example for illustration. The connection method of other light boards can be the same as the connection method between the light boards in this embodiment, or a combination of the connection methods in other embodiments can be adopted without limitation, and there is no limitation on the number of light boards connected by these connection methods.

[0051] Preferably, in some embodiments, the wire fixing structure 300 further includes a plurality of grooves (not shown) formed on the surface of each lamp board 110 , and the wires 200 are passed through the grooves.

[0052] Preferably, in some embodiments, the wire fixing structure 300 further includes a first spacer 330 disposed in the gap 120, such as Figure 3 As shown, the first spacer 330 has a first through hole 331, and the first transition section 213 and the first corresponding transition section 223 both pass through the first through hole 331. Preferably, the first spacer 330 also has a second through hole 332, and the second through hole 332 is perpendicular to the first through hole 331. The third connection line 230 passes through the second through hole 332 and crosses the outer surface of the first spacer 330 to wrap around the first spacer 330. The third connection line 230 connects the first connection line 210 and the second connection line 220 by wrapping and binding the first spacer 330.

[0053] The first spacer 330 protects the wire 200 and reduces the cutting effect of the edge of the lamp board 110 on the wire 200; on the other hand, it maintains the gap distance between two adjacent lamp boards 110. Preferably, the size of the spacer 350 is appropriately selected according to the actual situation so that the minimum distance between two adjacent lamp beads on two adjacent lamp boards 110 is not greater than the distance between any two adjacent lamp beads to ensure the continuity of the display screen, and the gap distance does not hinder the relative rotation between the lamp boards.

[0054] In addition, this embodiment also provides other connection methods for connecting the wire 200 and the wire fixing structure 300 and crossing each lamp board 110, which are explained through the following embodiments.

[0055] Second embodiment

[0056] Specifically, in Figure 4 In the second embodiment shown, the only difference from the first embodiment is the way in which the wire 200 and the wire fixing structure 300 are connected to the light panel assembly 100 .

[0057] On the basis of the first embodiment, the first connecting line 210 further has a third connecting section 214, a second transition section 215, a third transition section 216 and a fourth connecting section 217, the wire fixing structure 300 includes a first through hole 310 and a second through hole 320, the first through hole 310 is opened in the first lamp board 111, the second through hole 320 is opened in the second lamp board 112, the third connecting section 214 is located on the first backlight surface 111b, the second transition section 215 passes through the first through hole 310, the third transition section 216 passes through the second through hole 320, the fourth connecting section 217 is located on the second light emitting surface 112a, and the third connecting section 214, the second transition section 215, the first connecting section 211, the first transition section 213, the second connecting section 212, the third transition section 216 and the fourth connecting section 217 are connected in sequence.

The third corresponding connecting section 224 is located on the first light emitting surface 111a, the second corresponding transition section 225 passes through the first through hole 310, the third corresponding transition section 226 passes through the second through hole 320, and the fourth corresponding connecting section 227 is located on the second backlight surface 112b.

The first transition section 213 and the first corresponding transition section 223 intersect in the gap 120 ; the second transition section 215 and the second corresponding transition section 225 intersect in the first through hole 310 ; the third transition section 216 and the third corresponding transition section 226 intersect in the second through hole 320 .

[0059] In the second embodiment, the first through hole 310 and the second through hole 320 are provided to complicate the insertion method of the first connecting wire 210 and the second connecting wire 220, thereby strengthening the connection between the wire 200 and the light board 110 and making the overall connection structure of the screen more stable.

[0060] Third embodiment

[0061] The connection method of the first and second embodiments is a two-wire connection method. The present invention also provides Figure 5 The third embodiment is shown in a single-wire connection manner.

[0062] In the third embodiment, compared with the first and second embodiments, the difference lies in the way in which the wire 200 and the wire fixing structure 300 are connected to the light panel group 100, such as Figure 5 The wire 200 shown uses a fourth connecting wire 240 instead of the first connecting wire 210 and the second connecting wire 220. The fixed structure 300 includes a plurality of threading components 340. The threading components 340 include threading holes or threading grooves. At least one threading component 340 is respectively arranged on the first light emitting surface 111a and the second light emitting surface 112a or on the first backlight surface 111b and the second backlight surface 112b. The fourth connecting wire 240 passes through each threading component 340 in sequence.

The wing 352 extends from the body of the second spacer 350 and is disposed on the first light emitting surface 111a and the second light emitting surface 112a.

[0065] Preferably, in some embodiments, two fourth connecting lines 240 may be used, and the fourth connecting lines 240 are respectively arranged on the light emitting side and the backlight side of the light panel assembly 100 for connection.

[0066] In the third embodiment, the light boards 110 are connected in series by continuously passing the fourth connecting line 240 through the threading member 340 arranged on one side of the light board group 100, without having to pass through the through holes or gaps 120 on the light board group 100 back and forth many times, thereby simplifying the threading structure and improving the production efficiency of the screen.

Other light boards in the embodiments may be copies of the example units or combinations of connection schemes of different embodiments, all of which belong to the concept of the present invention.

[0073] In summary, compared with the prior art, the light board group of the bendable light-emitting semiconductor display screen provided by the present invention is a plurality of light boards arranged side by side at intervals, a gap is formed between two adjacent light boards, and the plurality of light boards are connected by wires and a wire fixing structure to form a whole display screen.
