Based on the problem that exists among the prior art, this embodiment provides a Mini LED lamp plate connection structure, specifically as shown in fig. 1 and fig. 2, Mini LED lamp plate connection structure in this embodiment includes: the LED light assembly comprises a first lamp panel 100 and a second lamp panel 200 adjacent to the first lamp panel 100, wherein the first lamp panel 100 and the second lamp panel 200 are bilaterally symmetrical and are arranged in parallel, a plurality of Mini LEDs 300 are uniformly arranged on the first lamp panel 100 and the second lamp panel 200 respectively, a splicing gap 400 is arranged between the second lamp panel 200 and the first lamp panel 100, and the distance between the adjacent Mini LEDs 300 on the same lamp panel is a first distance L1; the Mini LED300 of the edge position of the first lamp panel 100 is adjacent to the Mini LED300 of the edge position on the second lamp panel 200 at the same horizontal position, the distance between the Mini LED300 and the edge position is a second distance L2, and the second distance L2 is smaller than the first distance L1.
The working principle of the Mini LED lamp panel connection structure provided by this embodiment is as follows:
at present, all Mini LEDs are fixed on a back plate in a lamp plate mode, certain splicing gaps exist between the lamp plates, and the gaps can form dark stripes on module subjectively due to no light source and reflection.
The Mini LEDs in the prior art are reflecting sheets pasted on the whole lamp panel, the design is similar to that of a common direct type backlight module, the distances between the Mini LEDs at the splicing seams are equal, namely the distances between the Mini LEDs at the splicing seams are consistent with those between two adjacent Mini LEDs on the same lamp panel, so that dark stripes cannot be generated at the splicing seams, but the cost is high.
Adjacent on same lamp plate in this embodiment distance between the Mini LED is first distance, and the distance between two adjacent Mini LED on first lamp plate is equidistant promptly, and the distance between two adjacent Mini LED on the second lamp plate also is equidistant to distance between two adjacent Mini LED on the first lamp plate is equal with the distance between two adjacent Mini LED on the second lamp plate. However, at the position of the seam allowance gap between the second lamp panel and the first lamp panel, the distance between the Mini LED at the edge position of the first lamp panel and the Mini LED at the edge position on the second lamp panel at the same horizontal position is a second distance, and because a seam allowance gap exists between the Mini LED at the edge position of the first lamp panel and the Mini LED at the edge position on the second lamp panel at the same horizontal position, if the second distance is equal to the first distance, under the condition that a reflector plate is not attached, the position of the seam allowance gap is relatively dark, and the seam allowance gap absorbs light, the distance between the Mini LED at the edge position of the first lamp panel and the Mini LED at the edge position on the second lamp panel at the same horizontal position is reduced, so that a dark stripe is prevented from appearing at the position of the seam allowance gap between two adjacent lamp panels; because this embodiment need not paste the reflector plate, its simple structure can practice thrift the cost, but also can save the time of bonding the reflector plate, consequently can improve the efficiency of Mini LED lamp plate production.
The beneficial effect of the Mini LED lamp plate connection structure that this embodiment provided lies in at least:
this embodiment is through reducing the distance between the Mini LED of the edge position on the Mini LED of the edge position of first lamp plate edge position and the second lamp plate of same horizontal position to avoid the piece clearance position department of two adjacent lamp plates to appear the dark strip, its simple structure is favorable to improving Mini LED lamp plate production efficiency, reduction in production cost.
In one embodiment, in conjunction with fig. 2, the second distance L2 is 70% -75% of the first distance L1. As described above, in this embodiment, the first distance L1 is the distance between the adjacent Mini LEDs 300 on the same lamp panel; second distance L2 does first lamp plate 100 edge position's Mini LED300 and same horizontal position the distance between the Mini LED300 of edge position on the second lamp plate 200, first lamp plate 100 with be provided with piece clearance 400 between the second lamp plate 200, in order to avoid the piece clearance 400 position department of two adjacent lamp plates to appear the dark strip, consequently, will second distance L2 sets up and is less than first distance L1.
Specifically, the second distance L2 is 70% -75% of the first distance L1. If the second distance L2 is too large, a dark stripe phenomenon occurs, and the light emitting effect of the Mini LED lamp panel is influenced; if the second distance L2 is too small, the light intensity between the second distances L2 is strong, which results in a bright position of the splice gap 400, and therefore, setting the second distance L2 as appropriate is critical to whether the splice gap 400 has dark stripes or bright light. The second distance L2 in this embodiment is 70% -75% of the first distance L1, which enables the luminance at the position of the patchwork gap 400 to be equalized.
In an embodiment, referring to fig. 2, the seam gap 400 between the first lamp panel 100 and the second lamp panel 200 is 0.3-1 mm. Preferably, the seam clearance 400 between the first lamp panel 100 and the second lamp panel 200 is 0.5 mm. It should be understood that the seam gap 400 between the first lamp panel 100 and the second lamp panel 200 is not limited to the above 0.5mm, and may be other situations, and is not limited herein.
In an embodiment, with reference to fig. 2, a seam gap 400 between the first lamp panel 100 and the second lamp panel 200 is 0.5mm, and the second distance L2 is 70% -75% of the first distance L1.
In one embodiment, in conjunction with FIG. 2, the first distance L1 is 20 mm. It should be understood that the first distance L1 is not limited to the 20mm mentioned above, and other situations are possible, and is not limited herein.
In an embodiment, with reference to fig. 2, the first distance L1 is 20mm, the splice gap 400 between the first lamp panel 100 and the second lamp panel 200 is 0.5mm, and the second distance L2 is 70% -75% of the first distance L1.
In an embodiment, with reference to fig. 2, the seam gap 400 between the first lamp panel 100 and the second lamp panel 200 is 0.5mm, the first distance L1 is 20mm, and the second distance L2 is 15 mm. In this embodiment, first lamp plate 100 with piece clearance 400 between second lamp plate 200 is 0.5mm, if piece clearance 400 position department does not paste the reflector plate, and first distance L1 and second distance L2 are the equidistance setting, second distance L2 is if setting up to 20mm, then piece clearance 400 position department can be because piece clearance 400 extinction leads to appearing the dark stripe phenomenon, then suppose that second distance L2 sets up to 4mm, first distance is 20mm, although piece clearance is 0.5mm, second distance L2 sets up to 4mm and can lead to piece clearance 400 position department to appear the highlight, the light intensity of second distance L2 can be stronger than the light intensity of first distance L1, piece clearance 400 can be very bright like this, lead to the phenomenon that the lamp plate can appear luminous unbalance.
In an embodiment, with reference to fig. 2, the seam gap 400 between the first lamp panel 100 and the second lamp panel 200 is 0.5mm, the first distance L1 is 10mm, and the second distance L2 is 7.5 mm.
