Description

Technical Field

[0001] This utility model relates to the field of display screen technology, specifically a high-brightness liquid crystal display module. Background Technology

[0002] As an important display device in modern technology products, liquid crystal display (LCD) modules are widely used in mobile phones, televisions, and computers. However, during use, the issue of high brightness and low brightness of LCD modules may be encountered. Because high-brightness LCD modules have higher brightness, the screen content remains clearly visible in well-lit environments, making them suitable for outdoor and high-brightness environments. For example, in outdoor environments or workshops with strong light, high-brightness LCD modules are required to ensure that the screen content is clearly visible.

[0003] A Chinese patent discloses a novel ultra-high brightness LCD display module (authorization announcement number CN218938714U). This patented technology, through the coordinated arrangement of the heat-absorbing plate, the first heat-conducting column, the connecting hole, the back plate, the heat sink, the second heat-conducting column, the heat sink, the heat-absorbing pipe, the third heat-conducting column, and the heat sink groove, achieves a relatively good heat dissipation effect for the ultra-high brightness LCD display module and avoids the situation where dust can easily enter the interior of the ultra-high brightness LCD display module, thereby ensuring the overall service life of the ultra-high brightness LCD display module. However, its heat dissipation effect is not good, and it is inconvenient to adjust its angle and direction. Utility Model Content

[0004] The purpose of this invention is to provide a high-brightness liquid crystal display module to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0009] As a further embodiment of this utility model: the inner sidewall of the fan housing is provided with an internal thread groove, one end of the fan cover is provided with an external thread opening, and several snap-fit ​​holes are provided on the other end face of the fan cover. The fan housing and the fan cover are connected by the engagement of the external thread opening and the internal thread groove.

[0010] As a further embodiment of this utility model: the adjusting seat includes a slot post and a fixing post, a plug is embedded in the inner side of the slot post, a first hand-tightening bolt is embedded between the slot post and the plug, and a first flange is fixedly connected to one end of the plug.

[0011] As a further embodiment of this utility model: a rotating shaft is fixedly connected to one end of the slot post, a shaft hole is opened on the inner side of the fixed post, and a second flange is fixedly connected to one end of the fixed post. The rotating shaft is embedded in the shaft hole, and a second hand-tightening bolt is embedded between the rotating shaft and the fixed post.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention uses a heat sink to absorb the heat generated by the LCD screen and backlight module; then transfers the heat to the coolant inside the water pipe; the coolant, after absorbing heat in the water pipe, is pumped into the water tank by a water pump, and the heat in the water tank is transferred to the fins. A fan generates negative pressure, which can exhaust the heat on the fins to the outside; a motor drives a cleaning brush to rotate, which brushes the sides of the mesh to remove dust and impurities, which are then discharged by the fan, ensuring efficient heat dissipation.

[0014] The angle of the panel can be adjusted by adjusting the angle between the slot post and the plug; the orientation of the panel can be adjusted by rotating the fixed post along the rotation axis. Attached Figure Description

A water pump 42 is installed at the upper end of the water tank 41. A water pipe 44 is provided between the output end of the water pump 42 and the lower end of the water tank 41. The water tank 41 is filled with coolant. The coolant is pumped into the water pipe 44 by the water pump 42. The coolant in the water pipe 44 absorbs heat and then flows back into the water tank 41, transferring the heat in the water tank 41 to the fins 43 to achieve heat dissipation. The water pipe 44 is embedded inside the heat sink 5. The heat sink 5 absorbs the heat generated by the LCD screen 3 and the backlight module 2 and then transfers the heat to the coolant inside the water pipe 44. The fins 43 are facing the cooling fan 6, so that the heat in the water tank 41 can be discharged by the cooling fan 6.

A motor 66 is installed on one side of the mesh 67, and a cleaning brush 64 is installed on the other side of the mesh 67 at the output end of the motor 66. The negative pressure generated by the fan 62 can dissipate the heat on the fins 43 to the outside. When a lot of dust and impurities accumulate on the mesh 67, the motor 66 drives the fan to dissipate the heat. The cleaning brush 64 rotates and brushes the side of the mesh 67 to remove dust and impurities, which are then discharged through the fan 62. The inner wall of the fan housing 61 has an internal threaded groove 63, and one end of the fan cover 65 has an external threaded opening 69. Several snap-fit ​​holes 68 are provided on the other end of the fan cover 65.
