Description

Technical Field

[0001] The present invention relates to the technical field of liquid crystal display screens, and in particular to a high-brightness and high-contrast liquid crystal display module. Background Art

[0002] For example, the patent publication number CN203595879U is a high-contrast black film liquid crystal display with dye liquid crystal, which includes an upper glass substrate and a lower glass substrate. A black film, an upper ITO conductive layer, an upper PI orientation layer, a liquid crystal layer, a lower PI orientation layer, and a lower ITO conductive layer are arranged between the upper glass substrate and the lower glass substrate from top to bottom. The liquid crystal layer is provided with plastic balls that act as intervals and is filled with dye liquid crystals. The upper glass substrate and the lower glass substrate are sealed by edge sealing glue. The dye liquid crystal replaces the ordinary liquid crystal of the traditional liquid crystal display. Since the dye liquid crystal has the function of absorbing light, the background blackness of the liquid crystal display can be increased, the light transmission of the non-display area can be avoided, the contrast can be improved, and the viewing angle can be widened.

[0003] However, during the use of the above-mentioned device, due to the setting of the upper and lower glass substrates inside the device, the protection ability of the current ultra-high contrast LCD screen is poor, and there is a poor heat dissipation ability and it is easy to be immersed in water, which causes the electronic components in the ultra-high contrast LCD screen to be easily damaged by high temperature, thereby affecting the life and reliability of the LCD screen. At the same time, due to the different installation environments, it is not convenient to install and disassemble quickly, which reduces work efficiency. Therefore, in response to this situation, we propose a more convenient and practical LCD display module to meet the usage needs. Summary of the invention

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] During the use of televisions and computers, a display screen is required. The display screen provided by the present invention is specifically used for the screen display of televisions and computers. When using this device, it should be noted that the waterproof frame 301 and the dust-proof plate 303 should be kept intact to prevent water and dust from entering the module interior to protect the performance of the display screen. Regularly check whether the heat dissipation fan 411 is working properly to keep the channel unobstructed to prevent damage to the module caused by overheating. At the same time, the heat dissipation system needs to be regularly cleaned to ensure the heat dissipation effect. Avoid placing the module in an environment with extreme temperatures, high humidity or strong direct sunlight to avoid affecting its display effect and service life.

Four corners on one side of the waterproof frame 301 are fixedly connected with first threaded posts 302. A dust-proof plate 303 is arranged on one side of the waterproof frame 301. A connecting block 304 is fixedly connected to one side of the dust-proof plate 303, and the connecting block 304 is screwed with the first threaded post 302. A notch is opened at the top of the dust-proof plate 303, and an adsorption plate 305 is inserted into the notch. A silica gel particle plate 306 is inserted into the inner wall of the adsorption plate 305. Two sides of the dust-proof plate 303 are fixedly connected with first fixing blocks 307. A notch is opened on one side of the first fixing block 307, and a connecting plate 308 is inserted into the notch. Two sides of the connecting plate 308 are fixedly connected with heat dissipation plates 309. A heat dissipation mechanism 4 is arranged on one side of the protection mechanism 3. An adjustment mechanism 5 is arranged on one side of the heat dissipation mechanism 4. A connecting mechanism 6 is arranged on one side of the adjustment mechanism 5.

[0028] It should be noted that during use, first embed the display screen main body 1 into the rubber plate 2.

A first clamping block 506 is screwed on the top of the second threaded column 505. The second threaded column 505 penetrates through the fixed rod 503. Notch openings are opened at the tops of the first adjusting plate 501 and the second adjusting plate 504, and a third threaded column 507 is slidably connected in the notch openings. One end of the third threaded column 507 is screwed with a second clamping block 508, and the other end is fixedly connected with a rubber threaded block 509. A threaded hole is opened at the top of the rubber threaded block 509, and the threaded hole is adapted to the first threaded column 302. A second spring 510 is installed on one side of the rubber threaded block 509, and one end of the second spring 510 is in contact with the space between the first adjusting plate 501 and the second adjusting plate 504. Third fixing blocks 511 are fixedly connected to the inner walls of one sides of the first adjusting plate 501 and the second adjusting plate 504. Notch openings are opened at the tops of the third fixing blocks 511, and the notch openings are adapted to and inserted with the second limiting block 408.

[0032] It should be noted that during use, first, according to the size of the display screen main body 1, adjust the distance between the first adjusting plate 501 and the second adjusting plate 504 through the fixed pipe 502 and the fixed rod 503 and fix it through the first clamping block 506 and the second threaded column 505. Then manually adjust the position of the third threaded column 507 on the first adjusting plate 501 and the second adjusting plate 504, and rotate the second clamping block 508 to connect the rubber threaded block 509 and the first threaded column 302 under the action of the second spring 510. Finally, insert the heat dissipation mechanism 4 into the third fixing block 511, and the adjusting mechanism 5 adjusts the height and angle of the display screen to adapt to different viewing angle requirements and improve the viewing experience.

Then, the third clamping block 604 is manually rotated to clamp the first rotating plate 601 and the second rotating plate 602 under the action of the fourth threaded column 603. Then, the sliding rod 605 is manually taken out from the first rotating plate 601 and the second rotating plate 602 and fixed by the limiting rod 607. Finally, the entire device is connected to the wall or other support members through the screw 606.

Then, the connecting plate 308 and the heat dissipation plate 309 are inserted into the fixing block. The connecting frame 404 is installed on the mounting plate 401 through the limiting block and the fixing block. Then, the flow equalizing plate 405 is inserted.
