Problems solved by technology

[0002] The LED lamp beads in the small-pitch display screen (for example, the display screen with a dot pitch of 1.6mm and below) are relatively fragile. Manufacturers generally use the process of veneer cover to protect the LED lamp bead. However, the operation process of the veneer cover is easy to damage the LED lamp bead. cause damage, and due to the small spacing between the LED lamp beads, the holes on the mask for the LED lamp beads to pass through will be very small and dense, resulting in a more fragile structure of the mask itself, making the mask in the actual use process. Lamp bead protection is very limited
In addition, the manufacturing difficulty and high cost of the existing display screen mask

Embodiment 1

[0072] Please refer to Figure 1 to Figure 3 , Embodiment 1 of the present invention is: the preparation process of display screen mask, comprises the following steps:

[0073] S1. Provide a light board 1 with LED lamp beads;

[0074] S2. Set the rubber blocking frame 2 so that the lamp board 1 is located in the hollow area of ​​the rubber blocking frame 2, and make the peripheral wall of the lamp board 1 fit the inner wall surface of the rubber blocking frame 2;

[0075] S3, filling the hollow area of ​​the glue blocking frame 2 with glue I3, and making the glue I3 cover the LED lamp beads;

[0076] S4. Provide a pressing plate 5, set an isolation layer on the upper surface of the glue I3 or the bottom surface of the pressing plate 5 close to the glue I3, and use the weight of the pressing plate 5 to squeeze the excess glue I3 from the gap between the rubber retaining frame 2 and the pressing plate 5 out;

[0077] S5, glue Ⅰ3 curing;

[0078] S6. Remove the pressing plate...

Embodiment 2

[0095] Embodiment 2 of the present invention is another technical solution provided on the basis of Embodiment 1 for the type of glue I. The difference from Embodiment 1 is that the glue I is UV glue.

[0096] The preparation process of the display screen mask comprises the following steps:

[0097] S1. Provide light panels with LED lamp beads;

[0098] S2. Set the rubber blocking frame so that the lamp board is located in the hollow area of ​​the rubber blocking frame, and make the peripheral wall of the lamp board fit the inner wall surface of the rubber blocking frame;

[0099] S3, filling the hollow area of ​​the glue blocking frame with UV glue, and making the UV glue cover the LED lamp beads;

[0100] S4. Provide a transparent pressure plate, set an isolation layer on the upper surface of the UV glue or on the bottom surface of the transparent pressure plate close to the UV glue, and use the weight of the transparent pressure plate to extrude excess UV glue from the gap...

Embodiment 3

[0107] The third embodiment of the present invention is: the preparation process of the display screen mask, evenly spraying nano-matte black varnish between the LED lamp beads of the lamp board in advance, putting the lamp board into the oven to heat up to 60-90°C, and keeping it warm for 20-30 minutes, The varnish is cured to form a matte effect, thereby increasing the contrast of the light panel and ensuring the consistency of the black screen.

[0108] Take out the lamp board and set a continuous limit piece on the outer periphery of the lamp board, so that the protruding height of the limit piece is flush with the lamp surface on the lamp board. Specifically, use glue II and / or high-temperature tape to seal the adjacent two The gap between the two limit pieces, to avoid the gap between the limit pieces after glue filling after glue leakage. Preferably, the limiting sheet is a PVC sheet, a Mylar sheet, or the like.

[0109] Preferably, after coating the two-component mold...

Abstract

The invention discloses a preparation process of a display screen mask and a display screen, comprising the following steps: S1, providing a lamp board provided with LED lamp beads; S2, setting a rubber retaining frame so that the lamp board is located in the hollow of the rubber retaining frame area, and make the peripheral wall of the lamp board adhere to the inner wall of the rubber blocking frame; S3, fill the hollow area of ​​the rubber blocking frame with glue I, and make the glue I cover the lamp beads; S4, provide a pressure plate , set an isolation layer on the upper surface of the glue Ⅰ or the bottom surface of the pressure plate close to the glue Ⅰ, and use the weight of the pressure plate to squeeze out the excess glue Ⅰ from the gap between the rubber retaining frame and the pressure plate; S5, the glue Ⅰ solidifies; S6 , Remove the pressure plate and the rubber blocking frame. There is no need to additionally assemble the mask and the lamp board to ensure that the mask will not damage the lamp beads, which improves the yield of display products; the gap between the lamp beads is completely filled by the mask, so that the lamp beads are fully protected.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to a preparation process of a display screen mask and a display screen. Background technique [0002] The LED lamp beads in the small-pitch display screen (for example, the display screen with a dot pitch of 1.6mm and below) are relatively fragile. Manufacturers generally use the process of veneer cover to protect the LED lamp bead. However, the operation process of the veneer cover is easy to damage the LED lamp bead. cause damage, and due to the small spacing between the LED lamp beads, the holes on the mask for the LED lamp beads to pass through will be very small and dense, resulting in a more fragile structure of the mask itself, making the mask in the actual use process. The protective effect of lamp beads is very limited. In addition, the existing display screen mask is difficult and expensive to manufacture. [0003] Therefore, it is necessary to provide a new ...
