[0027] Example 1, as Figure 1 and Figure 2 shown, an LED backlight with a bottom-lighted line includes a monitor 1, a back panel 2 is provided on the monitor 1, a light source strip 3 is provided in the monitor 1, and a placement groove 6 is opened on the monitor 1.

[0028] Refer to Figure 2, a connection structure 4 is provided in the display 1. The connection structure 4 is mainly composed of two magnetic strips 41. Both of the two magnetic strips 41 are fixedly connected in the placement groove 6. A metal thin plate 42 is fixedly connected to the light source strip 3. The light source strip 3 is clamped in the placement groove 6, so that the two magnetic strips 41 adsorb the metal thin plate 42, and thus the light source strip 3 can be quickly installed and conveniently disassembled. This avoids the situation that when installing the current bottom bright line LED backlight, most of them use adhesives to fixedly adhere the light source strip 3 to the bottom edge of the screen. When the light source strip 3 is damaged, it is difficult to replace it, resulting in a reduction in practicality. Two fixing blocks 43 are fixedly connected to the placement groove 6. Sliding grooves 44 are respectively opened on both sides of the display 1. A slider 45 is slidably connected in the sliding groove 44. A clamping block 46 is fixedly connected to the slider 45. The two ends of the light source strip 3 are respectively placed on the two fixing blocks 43, and then the slider 45 is slid, so that the clamping block 46 and the fixing block 43 clamp the two ends of the light source strip 3. A first spring 47 is fixedly connected to the slider 45. One end of the first spring 47 is fixedly connected to the inner wall of the sliding groove 44. When the clamping block 46 and the fixing block 43 clamp the light source strip 3, the first spring 47 is in a contracted state. Therefore, the elastic force of the first spring 47 acts on the slider 45, making the limit of the light source strip 3 more stable. Rubber pads 48 are fixedly connected to the two contacting surfaces of the fixing block 43 and the clamping block 46. The rubber pads 48 can prevent the rigid contact between the clamping block 46 and the fixing block 43 and the light source strip 3 from damaging the light source strip 3.

[0029] Refer to Figure 3 and Figure 4, an installation structure 5 is provided on the backplane 2. The installation structure 5 is mainly composed of an installation groove 51. The installation groove 51 is opened on the backplane 2. An installation block 52 is fixedly connected to the display 1, and a sealing ring 53 is fixedly connected to the display 1. By snapping the installation block 52 into the installation groove 51, the display 1 can be quickly installed on the backplane 2. The sealing ring 53 can improve the sealing performance of the installation, making it more convenient to repair and replace the light source strip 3. Two relief grooves 54 are respectively opened on the inner walls on both sides of the installation groove 51. A clamping block 55 is slidably connected in the relief groove 54. Two clamping grooves 56 are respectively opened on both sides of the installation block 52. By sliding the clamping block 55, the clamping block 55 is snapped into the clamping groove 56 to limit the installation block 52. A round rod 57 is fixedly connected to the clamping block 55. The round rod 57 is slidably inserted into the backplane 2. A pull ring is rotatably connected to the round rod 57. The staff can slide the round rod 57 to drive the clamping block 55 to move by pulling the pull ring, making the operation more convenient. A second spring 58 is sleeved on the round rod 57. One end of the second spring 58 is fixedly connected to the clamping block 55, and the other end of the second spring 58 is fixedly connected to the inner wall of the relief groove 54. During the process of the installation block 52 being snapped into the installation groove 51, the installation block 52 will push the inclined surface of the clamping block 55, causing it to snap into the relief groove 54. At this time, the second spring 58 will be compressed and contracted. Therefore, when the clamping block 55 contacts the clamping groove 56, the clamping block 55 will be snapped into the clamping groove 56 under the action of the rebounding elastic force of the second spring 58, making the operation more convenient.

[0030] Working principle: The light source strip 3 is clamped in the placement groove 6, so that the two magnetic strips 41 adsorb the metal thin plate 42, and the light source strip 3 can be quickly installed and conveniently disassembled. This avoids the situation where the current bottom-lit LED backlight is mostly fixed and adhered to the bottom edge of the screen using an adhesive when installing the light source strip 3. When the light source strip 3 is damaged, it is difficult to replace it, resulting in a reduction in practicality. Place the two ends of the light source strip 3 on the two fixing blocks 43 respectively, and then slide the slider 45 so that the clamping block 46 and the fixing block 43 clamp the two ends of the light source strip 3. When the clamping block 46 and the fixing block 43 clamp the light source strip 3, the first spring 47 is in a contracted state. Therefore, the resilient force of the first spring 47 acts on the slider 45, making the limit of the light source strip 3 more stable. The rubber pad 48 can prevent damage to the light source strip 3 caused by the rigid contact between the clamping block 46 and the fixing block 43 and the light source strip 3. Clamp the mounting block 52 into the mounting groove 51, and the display 1 and the backplane 2 can be quickly installed together. The sealing ring 53 can improve the sealing performance of the installation, making it more convenient to repair and replace the light source strip 3. Slide the clamping block 55 so that the clamping block 55 is clamped into the card slot 56 to limit the mounting block 52. The staff can drive the clamping block 55 to move by pulling the pull ring to slide the round rod 57, making the operation more convenient. During the process of clamping the mounting block 52 into the mounting groove 51, the mounting block 52 will push the inclined surface of the clamping block 55, causing it to be clamped into the relief groove 54. At this time, the second spring 58 will be compressed and contracted. Therefore, when the clamping block 55 contacts the card slot 56, the clamping block 55 will be clamped into the card slot 56 under the action of the resilient force of the second spring 58, making the operation more convenient.
