Description

Technical Field

[0001] This utility model relates to the field of transparent screen technology, and in particular to an LED circuit board splicing structure for a display screen. Background Technology

[0002] Currently, advertising displays are used in shopping malls, lobbies, airports, and other venues for information guidance and product display. Recently, the emerging transparent screen has also gradually penetrated the advertising display market, gaining increasing popularity due to its transparency, lightness, and ease of use.

[0003] Transparent screens on the market generally consist of a frame and a display module mounted on the frame. The display module is composed of multiple LED circuit boards assembled sequentially. However, since LED circuit boards currently all use the same RGB LED bead arrangement design, please refer to the appendix for details. Figure 1 As shown, when splicing is required, after the LED circuit board is mirrored or rotated, the RGB arrangement order inside the LED beads becomes BGR. Therefore, when viewed from a distance, a region with significantly different colors will appear between the two LED circuit boards, which is known in the industry as the "yin-yang side". This will affect the display effect of the display module and the transparent screen, resulting in a poor user experience.

[0004] The common solution is to use two LED circuit boards with different lamp bead arrangements to weaken the negative and positive sides of the display module. However, this solution requires two different LED circuit boards, which increases the variety of LED circuit boards and the quantity and cost of product inventory.

[0005] Therefore, the optimization of displays is becoming increasingly necessary. Utility Model Content

[0011] In some embodiments, the LED circuit board comprises mounting portions on both sides and a light-transmitting display portion connected between the mounting portions, and the light-transmitting display portion is provided with light-transmitting holes arranged in a matrix.

[0022] Example 1: As Figures 2 to 5 As shown, this embodiment provides an LED circuit board splicing structure for a display screen, including at least two LED circuit boards 1. A plurality of forward LED display modules 10 and reverse LED display modules 20 are disposed on the LED circuit boards 1. The forward LED display modules 10 and the reverse LED display modules 20 are spaced apart. The forward LED display module 10 includes a plurality of spaced RGB LED beads 100, and the reverse LED display module 20 includes a plurality of spaced BGR LED beads 200. When the two LED circuit boards 1 are spliced ​​together, the forward LED display modules 10 and the reverse LED display modules 20 on the two LED circuit boards 1 are symmetrically distributed along the splicing seam between the two LED circuit boards 1.

[0023] The LED circuit board splicing structure of the display screen provided in this embodiment can reduce the negative and positive aspects of the display module and improve the user's usage and viewing experience.

[0024] Specifically, the forward LED display module 10 and the reverse LED display module 20 are spaced apart on the LED circuit board 1. The forward LED display module 10 includes several RGB LED beads 100 spaced apart, and the reverse LED display module 20 includes several BGR LED beads 200 spaced apart. The two different types of RGB LED beads 100 and BGR LED beads 200 are integrated and set on the LED circuit board 1, that is, they are reversed row by row. When the two LED circuit boards 1 are spliced ​​together, when viewed from a distance from the transparent screen, there will be no obvious color inconsistency between the two LED circuit boards. This weakens the unevenness of the light and dark areas in the overall display, thereby ensuring the display effect of the display module and the transparent screen and improving the user's use and viewing experience.

[0025] Furthermore, the LED circuit boards 1 used in the splicing adopt the same structure. When splicing, it is only necessary to mirror or rotate one of the LED circuit boards 1 to splice them together. This can effectively reduce the types of LED circuit boards and reduce production and inventory costs.

[0026] In this embodiment, the RGB LED bead 100 includes R LED beads, G LED beads and B LED beads arranged sequentially along the direction away from the splice seam;

[0027] The RGB LED beads 200 include B LED beads, G LED beads and R LED beads arranged sequentially along the direction away from the splicing seam. Its structure is simple and its design is reasonable. Through the aforementioned design, the LED beads can be set to be reversed row by row, thereby weakening the shadows on the overall display, thus ensuring the display effect of the display module and the transparent screen, and improving the user's use and viewing experience.

[0028] In this embodiment, the LED circuit board 1 includes mounting portions 11 on both sides and a light-transmitting display portion 12 connected between the mounting portions 11 on both sides. The light-transmitting display portion 12 is provided with light-transmitting holes 120 arranged in a matrix. Its structure is simple and its design is reasonable, which facilitates the installation of the LED circuit board 1. The light-transmitting holes 120 can be used to realize the light transmission display of the LED circuit board 1 and the display module.

[0029] Furthermore, the RGB LED beads 100 or the BGR LED beads 200 are provided in the non-transparent area between adjacent light-transmitting holes 120. This design is reasonable and can realize the light-transmitting display of the LED circuit board 1 and the display module, and avoid the RGB LED beads 100 or the BGR LED beads 200 from blocking the light-transmitting holes 120 and affecting the transparent display effect of the display module and the transparent screen.

[0030] Furthermore, an electrical connection component 2 is provided on the mounting part 11. The electrical connection component 2 is electrically connected to the forward LED display module 10 and the reverse LED display module 20. Its structure is simple and its design is reasonable, which facilitates the external electrical connection of the LED circuit board 1 and the power supply to the forward LED display module 10 and the reverse LED display module 20, thereby improving the assembly efficiency of the product.

[0031] In this embodiment, the light-transmitting hole 120 is circular, and a semi-circular light-transmitting hole 121 is provided at the edge of the light-transmitting display part. When two LED circuit boards 1 are spliced ​​together, the semi-circular light-transmitting holes 121 at the edges of the two LED circuit boards 1 are spliced ​​into a complete circular light-transmitting hole 120. Its structure is simple and its design is reasonable. This can further reduce the occurrence of obvious color inconsistencies between the two LED circuit boards, further weaken the negative and positive aspects in the overall display, ensure the display effect of the display module and the transparent screen, and improve the user's use and viewing experience.

[0032] The LED circuit board splicing structure provided in this embodiment can be applied to transparent screens, and of course, it can also be applied to non-transparent screens.

[0033] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
