[0026] Hereinafter, with reference to the accompanying drawings, the preferred embodiments of the present application are described in detail. In the following description, the same symbols are given to the same components, and repeated descriptions are omitted. In addition, the accompanying drawings are only schematic diagrams, and the ratio of the sizes of the components to each other or the shapes of the components may be different from the actual ones. It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0027] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0028] With the rapid development of science and technology, display devices have been used more and more widely. Among them, large display devices usually have display panels composed of multiple light panel units. However, as a spliced ​​display panel, it usually has the problem of unevenness after splicing, which affects the coherence and integrity of the display and the display effect is not good.

[0029] In view of the above technical problems in the prior art, Figures 1 to 5 The present application provides a display panel 100, which includes a light board and a light board unit 10. The light board includes a plurality of light board units 10 spliced ​​to each other, any two adjacent light board units 10 abut against each other, each light board unit 10 includes a display surface and a display back surface that are relatively arranged, and the display surfaces of all light board units 10 are in the same plane; a colloid 40 is located on the display back surface of the light board unit 10, and any two adjacent light board units 10 are connected by the colloid 40.

[0030] According to the above structure, the colloid 40 is located on the display back of the light board unit 10, which will not affect the display surface, and the connection through the colloid 40 can simplify the assembly process of the light board unit 10, the connection structure is simple, and it can also avoid the light board unit 10 causing gaps between adjacent light board units 10 due to the complex connection structure. Therefore, the display panel 100 provided by the utility model can have a higher flatness and a better display effect.

[0031] It should be noted that the display surfaces of all the light board units 10 described in this application are in the same plane, which means that extremely fine concave and convex structures can be ignored, that is, the display surfaces of all the light board units 10 are in the same plane to the extent visible to the naked eye. In addition, in the field of display technology, the display back of the light board unit 10 is usually arranged on the box body 30. Figure 2 In some examples, 25 light board units 10 are arranged in a matrix, and the 25 light board units 10 are arranged in a matrix of 5 rows and 5 columns on the box 30.

[0032] In some examples, each light board unit 10 has the same or similar size, and the orthographic projection of the light board unit 10 is a square, which can facilitate the preparation and splicing of the display panel 100. Figure 2 As shown, when 25 light board units 10 are spliced ​​and arranged in a matrix of 5 rows and 5 columns, the orthographic projection of the 25 light board units 10 is also a square. When 200 light board units 10 are spliced ​​and arranged in a matrix of 10 rows and 20 columns, the orthographic projection of the 200 light board units 10 is a rectangle.

[0033] Specifically, the display panel 100 is a Micro-LED display panel 100. When assembling and splicing the light board units 10, a reference plane can be selected first, and the display surface of each light board unit 10 is facing the reference plane and aligned with the reference plane. Multiple light board units 10 are arranged in a preset position matrix, and then glue is applied to the splicing of the display backs of two adjacent light board units 10. After the glue hardens, the multiple light board units 10 can be connected into an integrated structure.

[0034] Reference Figures 1 to 3 As an embodiment, the display panel 100 further includes a protective film 20, and the protective film 20 covers the display surfaces of all the light board units 10. In this way, a protective film 20 can cover the display surfaces of all the light board units 10, so that the flatness of the display panel 100 is higher, and the gap between the two light board units 10 can be covered. As a result, a smoother plane can be formed on the surface of the protective film 20, so that the display effect of the display panel 100 is better, and when the display panel 100 has a touch function, the user can write and touch more smoothly. In addition, the setting of a protective film 20 covering the display surfaces of all the light board units 10 can also provide more effective waterproof and moisture-proof protection to prevent water droplets from entering from the joints of the two light board units 10.

[0035] As another embodiment, the display panel 100 further includes a plurality of protective films 20, each of which covers the display surfaces of at least two light board units 10. Thus, the protective film 20 covers at least two light board units 10. In the related art, when the size of the display panel 100 is constant, the number of protective films 20 used can be reduced, thereby reducing the seams between the protective films 20 to improve the display effect; at the same time, for the plurality of light board units 10 covered by the same protective film 20, since there is no overlapping effect of the seams of the light board units 10 and the seams of the protective films 20, it is also helpful to improve the display effect at the seams of the light board units 10.

[0036] In the related art, the display surface of each light board unit 10 is provided with a layer of independent small film, but after the light board units 10 are spliced, a seam is likely to appear between two adjacent small films, and the seam is more obvious when touched. After a long period of use, dust may even accumulate at the seam, and the existence of the seam also affects the smoothness of writing, and the small film may be lifted when writing. Therefore, in the above embodiment, by reducing the use of the protective film 20, the problem of many seams of small films in the related art can be solved.

[0037] Specifically, in some examples, the protective film 20 is bonded to the surface of the display surface of the light board unit 10 , thereby achieving fixation between the protective film 20 and the light board unit 10 .

[0038] In some examples, the area of ​​the protective film 20 may be greater than or equal to the sum of the areas of the display surfaces of all the light board units 10. Thus, the protective film 20 can just cover the display surfaces of all the light board units 10, or the protective film 20 may be slightly larger than the display surfaces of all the light board units 10. When the protective film 20 is larger than the display surfaces of all the light board units 10, the excess protective film 20 may be cut by a cutting device to fit the size of the display surfaces of all the light board units 10.

[0039] As an embodiment, the colloid 10 includes a first adhesive strip and a second adhesive strip, wherein the first adhesive strip extends along the length direction of the display panel 100 to connect the plurality of light board units 10, and the second adhesive strip extends along the width direction of the display panel 100 to connect the plurality of light board units 10. In this way, the edges of two adjacent light board units 10 can be completely bonded by the first adhesive strip or the second adhesive strip, and the connection is more secure.

[0040] As an embodiment, at the junction of the four light panel units 10 arranged in a matrix, the first glue strip and the second glue strip are overlapped. Specifically, the four light panel units 10 arranged in a matrix refer to four light panel units 10 that are adjacent in both the length direction and the width direction of the display panel 100. It can be understood that the third glue section overlaps with the fourth glue section, that is, in the process of gluing, at the connection between two adjacent light panel units 10, glue can be continuously applied along the length direction of the display panel 100, or glue can be continuously applied along the width direction of the display panel 100, which is more convenient to operate and more efficient in gluing.

[0041] In some embodiments, at the junction of the four light panel units 100 arranged in a matrix, the first adhesive strip has a first notch, and the second adhesive strip is passed through the first notch. It is understandable that during the gluing process, the second adhesive strip can connect the four light panel units 10 when passing through the junction of the four light panel units 10, so the first adhesive strip does not need to be repeatedly coated. At this time, the first adhesive strip is disconnected at the junction of the four light panel units 10, thereby saving materials. Similarly, in other embodiments, the second adhesive strip can connect the four light panel units 10 when passing through the junction of the four light panel units 10, and the first adhesive strip does not need to be repeatedly coated.

[0042] Reference Figure 4 As an embodiment, the colloid 40 includes a plurality of glue segments, and at least two of the glue segments are arranged at intervals between any two adjacent light board units 10. Specifically, it can be understood that glue is dispensed in multiple areas at the joint of the two light board units 10 so that the two adjacent light board units 10 can be connected and fixed. Therefore, the interval arrangement between the glue segments can save materials and reduce costs.

[0043] Reference Figure 4 As an embodiment, the plurality of adhesive segments include a first adhesive segment 401 and a second adhesive segment 402; along the length direction or width direction of the display panel 100, two adjacent light board units 10 are connected by the plurality of first adhesive segments 401; the second adhesive segment 402 is provided at the junction of the four light board units 10 arranged in a matrix to connect the four light board units 10. Thus, the second adhesive segment 402 connects the four light board units 10, which can fully improve the utilization rate of the second adhesive segment 402, further save materials, and reduce costs.

[0044] As an embodiment, the thickness of the colloid 40 is between 1.5 mm and 2 mm. On the one hand, the setting of the thickness of the colloid 40 can provide sufficient bonding strength to ensure the stability of the splicing of the light board unit 10 and avoid displacement or loosening of the light board unit 10 due to the colloid 40 being too thin. On the other hand, the colloid 40 can provide additional protection to a certain extent to prevent external dust, moisture, etc. from damaging the light board unit 10. In addition, the thickness of the colloid 40 should not exceed 2 mm. If the colloid 40 is set too thick, the material cost will increase. Therefore, the thickness of the colloid 40 between 1.5 mm and 2 mm is a suitable range that balances performance and cost.

[0045] As an embodiment, the width of the colloid 40 is between 6 mm and 8 mm. It is understandable that the width of the colloid 40 refers to the size of the colloid 40 perpendicular to the splicing line of two adjacent light board units 10. Therefore, the colloid 40 can provide sufficient bonding strength at this width to ensure that the splicing between the light board units 10 is firm, so as to withstand vibration and impact in daily use. In addition, if the width of the colloid 40 is too large, it may increase the material cost, while if it is too narrow, it may affect the splicing effect and durability. Therefore, the width of the colloid 40 between 6 mm and 8 mm is considered to be a suitable range that balances performance and cost.

[0046] As an embodiment, the colloid 40 is UV glue. Therefore, the UV glue can be quickly cured under ultraviolet light, which improves the efficiency of the splicing process and reduces the production time. The UV glue has a high bonding strength and can firmly bond the light board unit 10 to ensure the stability of the splicing. In addition, the UV glue has good temperature resistance, moisture resistance, and chemical corrosion resistance, adapts to various environmental conditions, and improves the durability of the display panel 100.

[0047] Reference Figure 6 and Figure 7 As an embodiment, a notch is provided on the edge of the light board unit 10 on the side away from the display surface, and the colloid 40 covers the notch. Thus, the colloid 40 can enter the notch, so that the two adjacent light board units 10 can also be bonded on the side, and the notch can also increase the contact area between the colloid 40 and the light board unit 10, thereby improving the connection effect. Figure 7 In some examples, when two adjacent light board units 10 have notches at corresponding positions, a groove can be formed when the two light board units 10 are spliced ​​together, and the groove can also accommodate more colloids 40, thereby more fully connecting the two light board units 10. Specifically, in the related art, the light board unit 10 is mainly composed of a PCB board and a large number of lamp beads soldered on the PCB board, and display is performed by the lamp beads. Therefore, the notch in the above embodiment can be opened on the PCB board.

[0048] In summary, the colloid 40 of the display panel 100 in the present application is located on the display back of the light board unit 10, which will not affect the display surface, and the connection through the colloid 40 can simplify the assembly process of the light board unit 10, the connection structure is simple, and it can also avoid the light board unit 10 causing gaps between adjacent light board units 10 due to the complex connection structure. Therefore, the display panel 100 provided by the utility model can have a higher flatness and a better display effect.
