Preferably, the length of the mask body is 49.88mm, width 49.88mm.
Preferably, the lamp hole width of frame of each through-hole is 0.20-0.22mm.
Preferably, the rear surface of the mask body is painted with 3M glue, and the mask body for being coated with 3M glue row is attached to 3M
In release paper.
Preferably, the mask body uses PC engineering plastics, is bumped into mold using accurate grid mold insert, passes through injection molding
Machine injection molding, and released mask body from mold using tablet pushing tow mode.
Preferably, the through-hole is square through hole.
Preferably, the mask body is integral into array grid structure, and mask body covers in LED illuminator.
Compared with prior art, the present invention provides a kind of LED display mask, has following advantageous effect：
(1), the LED display mask keeps LED aobvious by the way that the lamp hole width of frame of each through-hole is set as 0.20-0.22mm
Display screen can eliminate shadow and mosaic phenomenon, keep light efficiency display consistency more preferable, and display picture is more beautiful, clear.
(2), the LED display mask is bumped into mold using accurate grid mold insert, is passed through injection molding using PC engineering plastics
Machine injection molding, and released mask body from mold using tablet pushing tow mode, tablet pushing tow mode can make mask master
Body is unlikely to deform, and enhances display effect.
It is not directed to part in the device to be the same as those in the prior art or can be realized by using the prior art, structure of the invention
Simply, easy to operate.

In figure：1, mask body；2, through-hole；3,3M release papers.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
In the description of the present invention, it is to be understood that, term "upper", "lower", "front", "rear", "left", "right", "top",
The orientation or positional relationship of the instructions such as "bottom", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, merely to just

Specific azimuth configuration and operation, therefore be not considered as limiting the invention.
Embodiment 1
As shown in Figs. 1-3, a kind of LED display mask, including mask body 1, mask body 1 are equipped with several through-holes 2,
Through-hole 2 is right against the position of lamp bead in LED display.
The principle of the present invention：The mask of LED display is to protect LED display to be designed from accidental damage, to whole
The display effect of a screen body has vital effect, the present invention to show mask body 1 mounted on LED by the way of gluing
On screen board, the position of the 2 face LED display lamp bead of through-hole on mask body 1 can be such that the picture that display screen is shown seems
It is apparent beautiful.
Embodiment 2
As shown in Figs. 1-3, the length of a kind of LED display mask, mask body 1 is 49.88mm, width 49.88mm；
The lamp hole width of frame of each through-hole 2 is 0.20-0.22mm, and the lamp hole width of frame of each through-hole 2 is a point spacing, point spacing be from
The distance between pixel reflects pixel density two-by-two, put spacing and pixel density be display screen physical attribute, information capacity is then
It is the unit of quantity of the disposable shown information carrying capacity of unit area pixel density, point spacing is smaller, pixel density
Higher, unit area can disposably show that information capacity is more, be suitble to the distance of viewing closer；Point spacing is bigger, pixel density
Lower, unit area can disposably show that information capacity is fewer, be suitble to the distance of viewing remoter, and in addition putting spacing can also influence to show
The display effect of display screen, point spacing is bigger, is more susceptible to blackspot or mosaic phenomenon, mask point spacing in the prior art is equal
For 0.40-0.45mm, it is susceptible to shadow and mosaic phenomenon, the lamp hole width of frame of through-hole 2 of the invention is 0.20-
0.22mm, hence it is evident that a spacing is shortened, pixel density is improved, making unit area, disposably displayable information capacity increases,
The distance of viewing can be suitble to close, and avoid and blackspot and mosaic phenomenon occur, keep the effect of display more preferable；Mask body 1
Rear surface be painted with 3M glue, and 1 row of mask body for being coated with 3M glue is attached in 3M release papers 3, only need when in use by
3M release papers 3 are removed, and then mask body 1 is mounted on LED display plate, easy to operate；Mask body 1 uses PC engineerings
Plastics are bumped into mold using accurate grid mold insert, by injection molding machine injection molding, and use tablet pushing tow mode by mask body
1 releases from mold, and PC engineering plastics are by the third diphenol in dihydroxyl compound, the diphenyl carbonate in carbonate compound
Be polymerized polycarbonate resin is reacted by ester-interchange method (fusion method), is a kind of engineering thermoplastic modeling of function admirable
