The height sum of the thickness of body and described salient point is more than the height of led lamp beads.The salient point 6 of the present embodiment is arranged on square through hole four
In the mask body 1 at angle.
The thickness of described mask body is more than led lamp beads height 0.3mm-0.5mm with the height sum of described salient point.
The present embodiment on the basis of realizing the effect described in embodiment 1, due to the mask body in mask through hole periphery
It is provided with salient point, and makes the thickness of mask body and the height sum of salient point be slightly above the height of led lamp beads, lamp bead can be avoided
With the directly contact of plane, such that it is able to reach protection led lamp beads purpose.
Because the thickness general control of typically existing led display screen mask material of main part is within 0.7mm-0.8mm, and
The height of led lamp beads typically in more than 1.0mm, the height sum setting of the material thickness of mask body and described salient point is compared
High 0.3mm-0.5mm is the most suitable for led lamp beads.
In mask body, setting salient point 6 can enable led lamp beads to be protected by mask on the basis of not changing mask toughness
Shield, does not make led lamp beads exposed outside, it is to avoid lamp bead is stressed directly, and with other object direct friction, reduce lamp bead impaired general
Rate, improving product stability.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have been shown and described above.One's own profession
The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model also can
There are various changes and modifications, these changes and improvements both fall within the range of claimed this utility model.This utility model will
Protection domain is asked to be defined by appending claims and its equivalent.
