Embodiment 1

[0027] Please refer to figure 1 and figure 2 , Embodiment 1 of the present invention is: a mask, including several mask units 100 and several connection units 200, and the same connection unit 200 is shared between every adjacent four mask units 100 arranged in a matrix. The mask unit 100 includes a unit body 110 , and a first through hole 120 is opened on the unit body 110 . The mask unit 100 corresponds to a single lamp bead when installed and used, the lamp bead is inserted into the first through hole 120, the unit body 110 and the lamp bead are clamped and fixed instead of welded, and there is an initial distance between two adjacent mask units 100 , the initial distance refers to the initial distance after the installation is completed. In this embodiment, the connecting unit 200 can only limit the maximum distance between adjacent mask units 100 , but the distance between two adjacent mask units 100 is variable. Although the mask in the present embodiment is formed a...

Embodiment 2

[0031] Please refer to Figure 3 to Figure 10 , the second embodiment of the present invention is: a display module, including a lamp panel 400, a plurality of lamp beads 300 and a mask, the plurality of lamp beads 300 are arranged on the lamp panel 400 in a matrix, and the mask cover is arranged on the lamp 300 outside.

[0032] Such as Figure 4 to Figure 7 As shown, the mask includes a mask unit 100, the mask unit 100 includes a first block 130 engaged with the lamp bead 300, the connection unit 200 includes a second block 220 engaged with the lamp bead 300, and the mask passes through the first block 130 And the cooperation between the second block 220 and the lamp bead 300 is installed on the display screen, so that the connection between the mask and the display screen is firm and not easy to loosen. Optionally, a plurality of first blocks 130 are arranged opposite to each other on the mask unit 100 , the first blocks 130 are arranged in the shape of a rice or a cross,...

Embodiment 3

[0038] Please refer to Figure 11 and Figure 12 , the third embodiment of the present invention is: a mask, the mask includes several mask units 100, at least two mask units 100, in this embodiment, four mask units 100. The mask module also includes a connection unit 200, which is provided between two adjacent mask units 100, and in this embodiment, there are four connection units 200 in total. When the mask is installed and used, there is an initial distance between two adjacent mask units 100, which refers to the initial distance after the mask is installed on the PCB board, and the distance between two adjacent mask units 100 variable. The mask in this embodiment has an initial distance between two adjacent mask units 100, and the distance is variable. During the use of the mask, when the mask expands with heat and contracts with cold, the adjacent two mask units 100 The distance between them changes with the thermal expansion and contraction of the mask, which avoids t...

Abstract

The invention discloses a mask, comprising: a plurality of mask units, first through holes are opened on the mask units, each first through hole accommodates a lamp bead and is clamped with the lamp bead, and the two adjacent mask units There is an initial distance between them; at least one connection unit, the connection unit is used to connect multiple mask units, and there is a movable gap between the connection unit and each mask unit. Or, a display module, including a lamp board, a plurality of LED lamp beads and a mask, the plurality of LED lamp beads are arranged on the lamp board in a matrix, the mask cover is arranged outside the LED lamp beads, and the mask is the above-mentioned mask. Since there is an initial distance between two adjacent mask units, and the distance is variable, during the use of the mask, when the mask expands with heat and contracts with cold, the distance between two adjacent mask units expands and cools with the heat of the mask. shrinking and changing, avoiding the partial protrusion of the mask, thereby avoiding causing screen shadows and affecting the display effect.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to a mask and a display module with the mask. Background technique [0002] The existing LED display screens all need to install masks. However, because the thermal expansion coefficient of conventional mask materials is several times that of the PCB board, the mask will generate greater stress during the process of thermal expansion and contraction, resulting in local bulges of the mask, resulting in shadows on the screen. , affecting the display effect. Contents of the invention [0003] The purpose of the present invention is to provide a mask and a display module with the mask to solve the problem that the existing mask will generate a large stress in the process of thermal expansion and contraction, which will cause the mask to partially bulge, cause screen shadows, and affect the display effect. technical problem. [0004] In order to solve the above-mentioned ...
