Description

Technical Field

[0001] This utility model relates to the field of backlight technology, specifically to a miniaturized light source array backlight. Background Technology

[0002] Backlights provide uniform background light for display devices such as LCDs and electronic paper displays that do not emit light or have weak light-emitting capabilities, enabling the display devices to clearly display images, text, and other content.

[0003] Existing backlights are generally set up as a whole and cover a large area. When some areas inside the backlight are damaged or unable to provide backlight, the entire backlight needs to be replaced, which increases the wear and tear on the backlight.

[0004] Therefore, we propose a miniaturized light source array backlight to solve the above problems. Utility Model Content

[0005] In view of the problems existing in the current miniaturized light source array backlight, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a miniaturized backlight array, which solves the problem in the prior art that when a backlight is damaged, it is impossible to disassemble and replace only the damaged area.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

The backlight panel is fixedly disposed on the top of the fixed frame. A control circuit board is fixedly disposed on the inner wall of the fixed frame. The LEDs are fixedly disposed on the surface of the control circuit board.

[0009] A bottom block and a top block are fixedly embedded on both sides of the fixed frame, and an insertion limiting mechanism is provided between the bottom block and the top block. The insertion limiting mechanism is used to connect two adjacent backlights.

[0010] Preferably, the two adjacent bottom blocks and top blocks are staggered in height.

[0011] Preferably, the insertion limiting mechanism includes an insertion block, which is fixedly disposed at the bottom of the top block. The top of the bottom block has a limiting slot for inserting the insertion block. The bottom block has a cavity inside, which is connected to the limiting slot. A sliding magnetic block is slidably disposed inside the cavity. The outer wall of the insertion block is fixedly provided with a connecting groove. The inner wall of the connecting groove is fixedly provided with a magnetically conductive block. The sliding magnetic block is inserted into the connecting groove and magnetically engages with the magnetically conductive block.

[0013] Furthermore, guide grooves are provided on both sides of the inner wall of the cavity, and guide plates are slidably inserted inside the guide grooves. The guide plates are fixedly connected to the sliding magnetic blocks.

[0014] Preferably, the backlight panel is bonded and fixed to the fixing frame.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model, through the provided backlight and plug-in limiting mechanism, allows the backlight to be arranged in multiple rows. When a certain area of ​​the backlight is damaged, only the backlight component in that area needs to be replaced, thus improving the overall performance of the backlight.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a miniaturized light source array backlight.

[0026] This utility model provides, for example Figure 1-3 The miniaturized light source array backlight shown includes multiple backlights 1 arranged in a row. Each backlight 1 includes a fixed frame 2, a backlight panel 3, and LEDs 4. The backlight panel 3 is fixedly mounted on the top of the fixed frame 2. A control circuit board 5 is fixedly mounted on the inner wall of the fixed frame 2. The LEDs 4 are fixedly mounted on the surface of the control circuit board 5. The backlight panel 3 is bonded and fixed to the fixed frame 2.

[0027] The fixed frame 2 has a bottom block 6 and a top block 7 fixedly embedded on both sides respectively. The two adjacent bottom blocks 6 and top blocks 7 are staggered in height. A plug-in limiting mechanism is provided between the bottom block 6 and the top block 7. The plug-in limiting mechanism is used to connect two adjacent backlights 1.

[0028] When using the backlight as a whole, the entire backlight is set up as multiple arrayed backlight components, so that each backlight component can emit light stably. At the same time, two adjacent backlights can be quickly connected. When the backlight is working, if some areas are not working, the operator only needs to remove and replace the backlight component in the damaged area, thus avoiding the need to dismantle the entire backlight and improving the performance of the backlight.

[0029] In order to enable quick connection between two adjacent backlight components, such as Figure 2-3 As shown, the insertion limiting mechanism includes an insertion block 8, which is fixedly disposed at the bottom of the top block 7. The top of the bottom block 6 is provided with a limiting slot 9 for insertion of the insertion block 8. The bottom block 6 has a cavity inside, which is connected to the limiting slot 9. A sliding magnetic block 10 is slidably disposed inside the cavity. A return spring 12 is fixed between the sliding magnetic block 10 and the inner wall of the cavity. A connecting groove is fixedly disposed on the outer wall of the insertion block 8. A solenoid block 11 is fixedly disposed on the inner wall of the connecting groove. The sliding magnetic block 10 is inserted into the connecting groove and magnetically engages with the solenoid block 11. Guide grooves are provided on both sides of the inner wall of the cavity. A guide plate 13 is slidably disposed inside the guide groove. The guide plate 13 is fixedly connected to the sliding magnetic block 10.

[0030] When two adjacent backlights are connected, the sides of the backlight panels 3 on the surfaces of the two backlights 1 can contact each other. At this time, the top block 7 is set above the bottom block 6, and the corresponding insert blocks 8 are inserted into the limiting slots 9 to initially position the backlight 1. Then, the backlight 1 is powered on, so that the solenoid block 11 generates magnetic force to attract the sliding magnetic block 10. At this time, the sliding magnetic block 10 is inserted into the insert block 8 by the sliding support of the guide plate 13 and the guide groove overcoming the elastic force of the return spring 12. Through the staggered intersection of the sliding magnetic block 10 and the insert block 8, the connection between the bottom block 6 and the top block 7 can be completed, thus completing the combination of the two adjacent backlights 1. When it is necessary to remove the backlight, the power is turned off again, so that the return spring 12 pulls the sliding magnetic block 11 away from the insert block 8, which improves the efficiency of the backlight assembly disassembly and assembly.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
