Description

Technical Field

[0001] The utility model belongs to the technical field of transparent display screens, and in particular relates to a micron-level circuit transparent display screen. Background Art

[0002] The transparent display screen uses many tiny LED dot matrices on a substrate. Each LED dot matrix contains LED lamp beads of three basic colors: red, green and blue. They can emit light independently. By adjusting the brightness and color of the red, green and blue LED lamp beads of each LED dot matrix, various images and videos can be displayed on the LED transparent display screen. With a transparent substrate, objects behind the LED transparent display screen can be seen through it, which improves people's visual experience. However, the LED lamp beads need to be connected to power lines and signal lines. Therefore, too many lines will affect transparency and viewing comfort. In order to solve such problems, a micron-level line transparent display screen is proposed. Utility Model Content

[0004] To this end, the utility model proposes a micron-level circuit transparent display screen, which has the advantages of reducing the occupied area of ​​the transparent substrate by the signal line and the power line, and improving the visual experience of the transparent substrate.

[0011] According to an embodiment of the utility model, one side of the transparent substrate is a plane, and the LED lamp beads are located on the transparent substrate.

[0012] According to an embodiment of the utility model, the power line and the LED lamp beads are located in the same plane, and another part of the signal line extends to be located in the same plane as the LED lamp beads.

[0013] According to an embodiment of the utility model, the insulating layer includes a main body and a branch, the main body covers the upper surface of the power line and the upper ends of both sides of the power line, and the branch extends downward from the main body to connect to the transparent substrate.

[0014] According to an embodiment of the utility model, the support is in a vertical state.

[0015] The beneficial effect of the utility model is that the utility model adopts an insulating layer between the power line and the signal line, and while avoiding a short circuit between the power line and the signal line, a part of the signal line and the power line are overlapped, thereby reducing the area occupied by the signal line and the power line on the transparent substrate, increasing the area of ​​the transparent substrate that can see the object behind it, and improving people's visual experience.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The micron-level circuit transparent display screen of the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-Figure 3As shown, the micron-level circuit transparent display screen according to the embodiment of the utility model includes: a transparent substrate 1, an LED lamp bead 2, a power line 3 and a signal line 4 are provided on one side of the transparent substrate 1, a part of the signal line 4 overlaps with the power line 3 along the thickness direction of the transparent substrate 1 to reduce the arrangement area of ​​the signal line 4 and the power line 3 on the transparent substrate 1, an insulating layer 5 is formed at the overlap of the signal line 4 and the power line 3, two ends of the power line 3 are respectively connected to two adjacent LED lamp beads 2, and two ends of the signal line 4 are respectively connected to two adjacent LED lamp beads 2.

[0029] In the present embodiment, an insulating layer 5 is provided between the power line 3 and the signal line 4, so that a portion of the signal line 4 overlaps with the power line 3 while avoiding a short circuit between the power line 3 and the signal line 4, thereby reducing the area occupied by the signal line 4 and the power line 3 on the transparent substrate 1, increasing the area of ​​the transparent substrate 1 that can see the object behind it, and improving people's visual experience.

[0030] There are multiple LED lamp beads 2, and the multiple LED lamp beads 2 are arranged in a rectangular array.

[0031] In this embodiment, adjacent LED lamp beads 2 are arranged diagonally to reduce the connection length of the signal line 4 and the power line 3, thereby reducing the occupied area of ​​the transparent substrate 1.

[0032] The thickness of the insulating layer 5 is 60 μm-100 μm.

[0033] In this embodiment, the insulating layer 5 can adopt a printing process, which has low production cost and is applicable to a variety of insulating layer 5 materials. When the thickness of the insulating layer 5 is between 60μm-100μm, while ensuring the stability of insulation, the thickness of the insulating layer 5 is reduced and the number of printing times is reduced.

[0034] The width of the insulating layer 5 is greater than the overlap width of the signal line 4 and the power line 3 to ensure the stability of the insulation and avoid a short circuit between the signal line 4 and the power line 3 .

[0035] The transparent substrate 1 is glass-based, which has high transparency and high temperature resistance. While satisfying the visual effect, it can also meet the requirements of preparing thinner power lines 3 and other circuits.

[0036] The insulating layer 5 is a photosensitive ink, preferably Peters 2496 from Germany or thermosetting ink or solar ink WT01.

[0037] One side of the transparent substrate 1 is a plane, and the LED lamp beads 2 are located on the transparent substrate 1. That is to say, the LED lamp beads 2 are directly mounted on the surface of the transparent substrate 1, and the signal lines 4, the insulating layer 5 and the power lines 3 are prepared. There is no need to make other shapes on the transparent substrate 1, which reduces the production difficulty of the transparent substrate 1.

[0038] The power line 3 and the LED lamp beads 2 are located in the same plane, and the other part of the signal line 4 extends to the same plane as the LED lamp beads 2, that is, the middle section of the signal line 4 coincides with the power line 3, and one end of the signal line 4 extends to one side of the power line 3 to connect to the signal input end of one LED lamp bead 2, and the other end of the signal line 4 extends to the other side of the power line 3 to connect to the signal output end of another LED lamp bead 2, thereby realizing the signal connection of two adjacent LED lamp beads 2, and an insulating layer 5 is formed at the overlapping part of the signal line 4 and the power line 3.

[0039] The insulating layer 5 includes a main body 51 and branches 52 . The main body 51 covers the upper surface of the power line 3 and the upper ends of both sides of the power line 3 . The branches 52 extend downward from the main body 51 to connect to the transparent substrate 1 .

[0040] In this embodiment, the main body 51 is used to isolate the power line 3 and a part of the signal line 4. The main body 51 is located directly above the power line 3. The branch 52 extends downward from one side of the main body 51 to isolate the side wall of the power line 3 and another part of the signal line 4. There are two branches 52, corresponding to the two ends of the power line 3 respectively.

[0041] The support 52 is in a vertical state, and the signal line 4 corresponding to the support 52 is also in a vertical state, both of which are perpendicular to the transparent substrate 1, so as to reduce the size of the support 52 and reduce the shielding area of ​​the transparent substrate 1.

[0042] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0043] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
