Description

Technical Field

[0001] The present application relates to the technical field of backlight sources, and specifically to a curved backlight source. Background Art

[0002] A backlight is a light source located behind a liquid crystal display (LCD). Its primary function is to evenly illuminate the image on the back of the LCD, allowing the image to appear. The backlight directly impacts the visual quality of the LCD module, making its performance and quality crucial to the overall display system's performance.

[0003] For example, the Chinese utility model patent with publication number "CN219872049U" discloses a curved backlight source. The utility model installs the backlight source in a first fixing frame, and then presses the plug-in to insert the plug-in block, the plug-in block and the socket into the slot. When the plug-in is inserted to the end, the plug-in block reaches the square opening position and is no longer squeezed by the inner wall of the slot, thereby causing the spring to switch from the compressed state to the relaxed state, thereby driving the plug-in block and the plug-in block to move, so that the plug-in block is inserted into the square opening. When the second fixing mechanisms on all four sides are fixed, , the first fixing frame and the second fixing frame can be fixed, and then the heat dissipation fan can be installed on the mounting seat on the connecting plate. Finally, the knob can be rotated to match the through hole so that the insertion rod and the knob are inserted into the through hole. When the knob is located on the outside of the connecting plate, the knob can be rotated again so that the knob and the through hole are staggered, and the second fixing frame and the connecting plate can be fixed. When the backlight source generates more heat, the heat is sucked away from the heat dissipation holes by the heat dissipation fan and then discharged through the air outlet to achieve the heat dissipation effect. The filter is used to filter it during the discharge process.

[0004] In the above patent, the backlight source can be cooled and the interior of the device can be dust-proofed. However, after the device is used for a long time, dust may accumulate on one side of the filter plate, causing the filter plate to be blocked, affecting the ventilation inside and outside the device and thus affecting the heat dissipation effect of the device.
