Technical Field

[0001] The utility model relates to the technical field of LED backlight sources, and specifically to a small MiniLED backlight structure. Background Art

[0002] LED backlight is a lighting technology widely used in electronic devices, including backlight sources used in monitors, televisions, mobile phones and other devices. The principle of LED backlight is to use LED chips to generate light. These chips can convert electrical energy into visible light energy and can provide the advantages of high efficiency, long life and low energy consumption. Therefore, it has been widely used in modern electronic products.

[0003] When the LED backlight source is in use, a mounting structure is required to install the LED backlight source. During use, the existing mounting structure usually uses bolts to install and fix the LED backlight panel. However, when the backlight panel is disassembled, the bolts usually need to be unscrewed or cut off, so the backlight panel may be damaged during the disassembly process. In addition, when the backlight panel is disassembled and replaced, all the bolts need to be removed, which is cumbersome and affects the maintenance efficiency of the backlight panel.

[0004] Therefore, it is necessary to provide a new small MiniLED backlight structure to solve the above technical problems. Utility Model Content
