[0002] A backlight board is an important component in an electronic display or a liquid crystal TV. It is a light-transmitting panel used to provide background illumination. Since display materials such as liquid crystals do not emit light themselves, a backlight source must be used for illumination. The role of the backlight board is to place a light source behind the display and achieve backlight for the entire screen through the reflection and scattering of the light-transmitting panel.

[0003] Currently, the backlight display lamp board body is divided into direct-lit type and side-entry type. As Figure 1 shown, the side-entry backlight lamp board includes a lamp board body 1 and a plurality of LED lamp strips 2 provided on the lamp board body 1. In the existing side-entry lamp board body, the LED lamp strips 2 are assembled by using an inverted buckle method and are produced by a routing or die punching process. Among them, the distance between adjacent LED lamp strips 2 is generally designed to be 2.0 mm, which has the characteristics of large use area of the board, low effective utilization rate, high cost, and low SMT mounting efficiency.

[0026] Please refer to Figures 2 to 4 , which is a side-entry backlight display light board in the first embodiment of the present utility model, including a light board body 10 and a plurality of inverted buckle misaligned splicing structures provided on the light board body 10.

[0027] Wherein: The inverted misaligned layout structure includes two connected LED light bars 20. The spacing between adjacent inverted misaligned layout structures is the same. The LED light bar 20 includes a protrusion 21 and a long strip 22. The protrusion 21 is located on one side of the long strip 22. The protrusion 21 and the long strip 22 are combined to form the stepped structure. The long strip 22 is a cuboid structure, and the protrusion 21 is a cuboid structure. The protrusion 21 and the long strip 22 are integrally connected. The protrusion 21 and the long strip 22 are combined to form the corresponding circuit board. It should be noted that in order to shorten the distance between adjacent LED light bars 20, in the inverted misaligned layout structure, the end of the long strip 22 of one LED light bar 20 away from the protrusion 21 is close to the protrusion 21 of another LED light bar 20, and the long strip 22 of one LED light bar 20 and a part of the protrusion 21 of another LED light bar 20 are designed on the same straight line. The spacing between adjacent inverted misaligned layout structures is the same as the spacing between the two LED light bars in the inverted misaligned layout structure. Through this setting, the distance between adjacent LED light bars 20 can be shortened to 0.3 mm, reducing the usage area of the lamp board body 10 and improving the effective utilization rate of the board material.

[0028] In this embodiment, the two LED light bars 20 in the inverted misaligned layout structure are laser welded. Specifically, there are welding pads 23 provided on the lamp board.

It should be noted that the connection terminal 25 is equivalent to a connector, which is used to connect the external power supply to the LED lamp beads 26 so that the current can be normally supplied to the LED lamp beads 26.

[0030] In this embodiment, the LED lamp beads 26 and the terminals are respectively welded to the long strip 22 and the protrusion 21 through the SMT mounting process. The pads 27 are used to protect the LED lamp beads 26, and the height of the pads 27 is greater than the height of the LED lamp beads 26.

[0031] In specific implementation, the end of the strip portion 22 of the LED strip 20 away from the protrusion portion 21 is close to the protrusion portion 21 of the adjacent LED strip 20, and the strip portion 22 of the LED strip 20 and a part of the protrusion portions 21 of the adjacent LED strip 20 are on the same straight line, so that the adjacent LED strips 20 are combined to form an inverted and misaligned splicing structure. The two LED strips 20 in the inverted and misaligned splicing structure are connected by laser welding. Different from the prior art, it can not only reduce the usage area of the lamp board body 10, improve the effective utilization rate of the board material, and greatly reduce the cost of the lamp board body 10, but also be beneficial to improving the SMT mounting efficiency.
