Fig. 1 and 2 are schematic structural views illustrating an embodiment of a display screen mask assembly, and referring to fig. 1 and 2, the display screen mask assembly in the embodiment includes a mask body 100 and a bottom case 200, wherein the mask body 100 is disposed above the bottom case 200 for protecting a lighting element mounted on the bottom case 200; specifically, a circle of mounting steps 110 is arranged on the periphery of the mask body 100, the mounting steps 110 are recessed in a direction away from the mask body 100 and close to the bottom shell 200, one side of the mask body 100 close to the bottom shell 200 is embedded in the bottom shell 200, a circle of mounting frame 210 is arranged on the periphery of the bottom shell 200, after the mask body 100 is mounted on the bottom shell 200, a first accommodating cavity 120 is formed between the mounting steps 110 and the mounting frame 210, and the surface of the mounting frame 210 is not in contact with the mounting steps 110; display screen face guard subassembly is when assembling, the module is located the below of face guard body 100, when encapsulating the module, colloid 101 can hold in first holding cavity 120, when colloid 101 flows in first holding cavity 120 under the effect of surface tension, because of the surface of installation framework 210 and installation step 110 contactless, colloid 101 can be followed the overflow in the clearance between installation framework 210 and the installation step 110, face guard body 100 can not be because of receiving the ascending marginal warpage that exerts power and lead to face guard body 100 of colloid 101, and then improve the holistic roughness of display screen face guard subassembly.
In the display screen mask assembly of the embodiment, the first accommodating cavity 120 is disposed between the mounting step 110 of the mask body 100 and the mounting frame 210 of the bottom shell 200, and the colloid can be accommodated in the first accommodating cavity 120 and flow in the first accommodating cavity 120 under the action of surface tension, and because the mounting frame 210 is not in contact with the mounting step 110, even if the colloid 101 is higher than the surface of the mounting frame 210, the colloid can overflow from between the mounting frame 210 and the mounting step 110, and cannot prop against the mask body 100, so that the surface of the mask body 100 is kept flat.
It should be noted that the glue is filled before the mask body 100 and the bottom shell 200 are assembled, and the waterproof effect of the module is improved by filling the glue into the module. The colloid 101 is in a liquid state before solidification, can flow in the first accommodating cavity 120, is in a solid state after solidification of the colloid 101, and keeps a fixed shape; therefore, when the colloid 101 flows under the surface tension, the colloid overflows between the mounting step 110 and the mounting frame 210, and does not push up the mask body 100, and the mask body 100 is not warped after the colloid 101 is solidified.
Referring to fig. 3 and 4, the mask body 100 is provided with a plurality of mounting ribs 130, and the mounting ribs 130 extend in different directions and are distributed in a staggered manner to form a grid; in this embodiment, the adjacent mounting ribs 130 are perpendicular to each other, and the adjacent mounting ribs 130 along the same direction are parallel to each other, so that different mounting ribs 130 form a rectangular grid. One side orientation colloid that installation edges 130 are close to drain pan 200, the net that encloses between installation edges 130 forms the light trough 140 (not shown because of the lamp pearl is covered by the colloid in figure 1, figure 2) that is arranged in the holding module lamp pearl, and light trough 140 is array arrangement on face guard body 100, and the upper surface height that highly is less than light trough 140 of lamp pearl to avoid the lamp pearl to expose from light trough 140, and make the lamp pearl easily damaged. In this embodiment, the side of the mounting rib 130, i.e., the side wall of the lamp groove 140, is stepped, so as to provide a larger flowing space for the glue, thereby preventing the glue from being exposed from the lamp groove 140; bumps can be further arranged on the lamp grooves 140, so that the lamp beads are clamped with the bumps, and the structural stability between the lamp beads and the mask body 100 is improved; the mask body 100 is further provided with a plurality of positioning holes 150 at one side close to the bottom case 200, and the positioning holes 150 can be inserted into the module installed in the bottom case 200, so that the positioning between the mask body 100 and the module is realized, and the convenience in installing the mask body 100 is improved.
It should be noted that, the mounting rib 130 located at the outermost side of the mask body 100 is adjacent to the mounting frame 210, a second accommodating cavity 220 is formed between the mounting rib 130 and the mounting frame 210, the second accommodating cavity 220 is communicated with the first accommodating cavity 120, and the colloid can flow through the second accommodating cavity 220 and the first accommodating cavity 120 under the action of surface tension, so that the colloid can overflow through the first accommodating cavity 120, and the colloid 101 is prevented from propping the mask body 100. In this embodiment, the first accommodating cavity 120 is communicated with the second accommodating cavity 220 to form an "L" shape; on the one hand, installation framework 210 plays the effect of blockking to the colloid, prevents that the colloid from all overflowing, influences the encapsulation effect, and on the other hand, colloid accessible second holding cavity 220 gets into the overflow, avoids face guard body 100 warpage.
Referring to fig. 5, the mask body 100 is provided with a plurality of reinforcing ribs 160 on a side away from the bottom shell 200, the reinforcing ribs 160 are distributed at intervals and surround the periphery of each light trough 140, the reinforcing ribs 160 extending along the same direction are parallel to each other, and a groove 170 is formed between adjacent reinforcing ribs 160 in the same direction; on one hand, the structural strength of the mask body 100 is improved by the reinforcing ribs 160, and on the other hand, the grooves 170 and the lamp grooves 140 are visually mixed, so that the overall display consistency of the display screen mask assembly is improved, and the display effect is improved.
The utility model also provides a LED display screen, the LED display screen includes the above-mentioned display screen mask subassembly, still includes LED lamp plate 300, refer to fig. 1 and fig. 2, be equipped with support step 211 on the installation framework 210, LED lamp plate 300 erects on this support step 211, realizes the fixing between LED lamp plate 300 and drain pan 200; it should be noted that, an installation gap 212 is provided between the side portion of the LED lamp panel 300 and the side portion of the supporting step 211, and the installation gap 212 provides a flowing margin for the glue, so as to avoid that the glue flows to cause cracking between the LED lamp panel 300 and the bottom case 200 due to too tight connection between the LED lamp panel 300 and the bottom case 200, thereby affecting the assembly accuracy of the LED display screen.
Through set up display screen face guard subassembly in the LED display screen, can avoid face guard body 100 to hold the effect warpage down in the top of colloid 101 to improve the holistic plane degree of LED display screen, make each module have higher uniformity, optimize the display effect of LED display screen, promote user experience.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art. Furthermore, the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
