Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of miniLED backlight, and in particular to a miniLED backlight structure. Background Art
[0002] MiniLED backlight is a technology that uses tiny LED lamp beads as backlight sources.
[0003] like Figure 4 As shown, the conventional MINILED structure is composed of stacked lamp board film materials and frame (glue-iron) structures. The relevant lamp spacing (pitch) and OD values are certain values, and the optics are adjusted around these parameters to prevent uneven brightness. In addition, these values need to be precisely monitored during the assembly process to ensure stable batches and output to the module. Only then can the terminal products be reliably batched. Mini LED backlight technology requires the use of a large number of Mini LED chips, so the cost is relatively high. Secondly, a lot of time needs to be spent on research and development in the early stage of debugging; to maintain better optical effects, the fixed setting of the OD value is not convenient for debugging the miniLED backlight, and the debugging cost is high. For this reason, we propose a miniLED backlight structure. Utility Model Content
[0004] The utility model is to propose a miniLED backlight structure to solve the shortcomings existing in the prior art. The miniLED backlight structure solves the problem that the position of the diffusion plate is fixed, so that the OD value between it and the light board is fixed, and it needs to be completely disassembled for adjustment, which consumes a lot of cost and is not conducive to the miniLED backlight debugging.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A miniLED backlight structure includes a glue iron, one side of the glue iron is provided with an easy-pull adhesive, one side of the easy-pull adhesive is provided with a circuit board, a plurality of LED lamp beads are provided on the upper side of the circuit board, transparent silica gel is provided on the upper side of the circuit board, a plurality of adjustment grooves are provided on the inner wall of the glue iron, and a diffusion plate is provided in the adjustment groove.
[0007] Preferably, the number of the adjustment grooves is at least three.
[0008] Through the above technical solution, the diffuser plate can be placed in adjustment grooves of different heights, thereby changing the OD value between the diffuser plate and the LED lamp beads, providing an adjustable function for the OD value in the miniLED backlight structure.
[0009] Preferably, a transparent blue light film is provided on one side of the diffusion plate.
[0010] Preferably, a quantum dot film is provided on one side of the transparent blue light film.
[0011] Preferably, a plurality of light-homogenizing films are arranged on one side of the quantum dot film.
[0012] Preferably, a brightness enhancement film is provided on one side of the light-homogenizing film.
[0013] In summary, the utility model can place the diffusion plate in adjustment grooves of different heights, thereby changing the OD value between the diffusion plate and the LED lamp beads, and providing an adjustable function for the OD value in the miniLED backlight structure.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] like Figure 1-Figure 3As shown, a miniLED backlight structure includes a glue iron 1, a pull-out glue 2 is arranged on one side of the glue iron 1, a circuit board 3 is arranged on one side of the pull-out glue 2, a plurality of LED lamp beads 4 are arranged on the upper side of the circuit board 3, a transparent silica gel 5 is arranged on the upper side of the circuit board 3, a plurality of adjustment grooves 6 are arranged on the inner wall of the glue iron 1, the number of the adjustment grooves 6 is at least three, a diffusion plate 7 is arranged in the adjustment groove 6, a transparent support column is arranged between the diffusion plate 7 and the circuit board 3, the transparent support column is arranged between two LED lamp beads 4, a transparent blue light film 8 is arranged on one side of the diffuser plate 7, a quantum dot film 9 is arranged on one side of the transparent blue light film 8, a plurality of light-homogenizing films 10 are arranged on one side of the quantum dot film 9, and a brightness-enhancing film 11 is arranged on one side of the light-homogenizing film 10.
[0021] In this embodiment, the number of adjustment grooves 6 is at least three, and can be more, and is set according to usage requirements. The diffuser plate 7 is placed in the adjustment grooves 6 at different heights, so that the OD value formed between the LED lamp bead 4 and the diffuser plate 7 is different. The position is adjusted and changed according to usage requirements. At the same time, the pitch value between the two LED lamp beads 4 can be changed according to usage requirements. A space is left between the adjustment groove 6 and the glue iron 1. The circuit board 3 is installed on the glue iron 1 with the easy-pull adhesive 2. The circuit board 3 is combined with the LED lamp bead 4 to form a miniLED lamp board. The miniLED lamp boards with different pitch values can be disassembled and replaced, so that the miniLED backlight structure can switch the OD value and the miniLED lamp board pitch by itself during the early optical debugging, and the product can be quickly switched, thereby shortening the product development cycle and reducing the lamp board cost.
[0022] It should be noted that the maximum pitch value on the light board combined with the maximum OD value can minimize the cost, and this structure can ensure free switching operation of the light board.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
