In the field of LED display screens, a display module is a novel display mode. In order to ensure that the ink color of the whole screen assembled by the display module is consistent, the assembled display module needs to be sprayed with ink. However, the inventor of the present invention has noticed that when the assembled display module is sprayed, the coverage of the ink on the display module is not uniform, for example, the coverage on the edge of the display module is not uniform with the coverage on the middle portion, so that a white edge or a black edge appears on the display module.
Through the intensive research, the inventor discovers that the key causing the problems lies in that when the display module is sprayed, the connection tightness degree of the display module carrier and the display module is limited, and uneven stepped structures exist at the connection part of the display module carrier and the display module, so that the coverage rate of the ink at the edge of the display module is different from that of the ink at the middle position of the display module, the coverage rate of the ink on the display module is uneven, and the phenomenon of white edges or black edges easily occurs. In addition, because the position that is connected with the display module assembly on the display module assembly carrier is different with the material of display module assembly, and the handing-over border of display module assembly carrier and display module assembly is inconsistent promptly, leads to printing ink to cover the effect inconsistent with the cover effect at the middle part on certain width edge of display module assembly, further leads to the production of white limit or black edge phenomenon.
Based on the consideration, the inventor researches and discovers that a display module spraying process can be designed, the connection surfaces between the display module and the display module carrier can be mutually flush, seamless connection is realized, and the phenomenon of white edges or black edges is avoided, so that the display module is conveniently sprayed.
Fig. 1 is a schematic view illustrating an overall structure of a display module carrier according to an embodiment of the present invention, and fig. 2 is a schematic view illustrating a structure of a substrate according to an embodiment of the present invention. For the purpose of illustration, the drawings show only the structures associated with embodiments of the invention.
Referring to fig. 1, an embodiment of the present invention provides a display module spraying process, including the steps of:
and S10, fixing the display module in the loading slot 30 enclosed by the frame assembly 20, and supporting the display module on the carrying step 40 formed between the side of the frame assembly 20 facing the loading slot 30 and the substrate 10, so that the surface of the frame assembly 20 facing away from the substrate 10 is flush with the surface of the display module facing away from the loading slot 30.
In the embodiment, the display module is a COB module, and the COB module is generally a square structure, so the loading slot 30 enclosed by the frame assembly 20 is configured to be a square structure. Thereby can make COB module close fit in the loading bay 30, stability when improving the COB module and spout the oiling ink. Further, when the closely block of COB module is in loading tray 30, each limit of COB module respectively with each limit seamless connection of COB frame subassembly 20 to the upper surface of COB frame subassembly 20 and the surface that the COB module needs the spraying are on same horizontal plane. When printing ink spraying to COB module border position, can not receive sheltering from or influence of COB frame subassembly 20, consequently, the coverage of printing ink at COB module border position is the same with its coverage at COB module intermediate position. Make the coverage of printing ink on the COB module more continuous promptly to make the printing ink on the COB module more even. In addition, the bezel assembly 20 is made of the same material as the display module. That is, in the present embodiment, the bezel assembly 20 is a COB bezel assembly. Consequently, the coverage of printing ink on COB frame subassembly 20 and COB module can not receive the influence of material for the coverage homogeneous phase of printing ink on each position of COB module is the same, has further improved the homogeneity of printing ink on the COB module.
Referring to fig. 2, in step S10, the display module is accommodated in the loading slot 30 defined by at least one set of movable frames 21 and at least one set of fixed frames 22, and each set of movable frames 21 is controlled to move relative to the substrate 10, so that the loading space of the loading slot 30 matches the size of the display module disposed therein.
During the in-service use, display module often has multiple different specifications and sizes, consequently, through setting up movable frame 21, can change the loading space of loading groove 30 to make display module carrier 100 can be applicable to the display module of multiple different sizes, improve display module carrier 100's commonality.
Further, in step S10, the display module is accommodated in the loading slot 30 defined by the two sets of movable frames 21 and the two sets of fixed frames 22, such that two adjacent sides of the display module perpendicular to each other are respectively and tightly connected to the two sets of fixed frames 22, and the other two adjacent sides of the display module perpendicular to each other are respectively and tightly connected to the two sets of movable frames 21.
Wherein, two sets of fixed frames 22 are arranged vertically and combined to form an L-shaped structure. The two groups of movable frames 21 are perpendicular to each other and are constructed to form another L-shaped structure, and the two L-shaped structures enclose each other to form a loading slot 30 for bearing a square structure of the display module. Through controlling two sets of movable frames 21 to move relative to the substrate 10 along two mutually perpendicular directions respectively, the size of the loading space of the loading slot 30 is changed, and the size of the display module can be better matched.
S20, spraying module, with the spray gun just to the display module assembly setting, make the stable spraying of spraying on display module assembly and frame subassembly 20.
Specifically, after the position of the spray gun is set to enable the spray gun to be opposite to the display module, the prepared ink to be sprayed is firstly filtered by the filter screen in the stirring process. The filtered ink is ejected from the spray gun, after the spray is stable, the display module carrier 100 carrying the display module is conveyed at a constant speed through the conveyor belt to spray, and the spray gun is horizontally swept back and forth in the vertical direction of the conveying direction, so that uniform ink jet is realized.
And S30, the unloading module controls the two sets of movable frames 21 to move relative to the substrate 10 in the direction away from the display module respectively, so that the display module is separated from the two sets of movable frames 21 and the two sets of fixed frames 22, and the display module is separated from the loading slot 30.

When the ink is sprayed to the edge of the display module, the ink is not blocked or affected by the frame assembly 20, and therefore, the coverage rate of the ink at the edge of the display module is the same as that of the ink at the middle of the display module. Make the coverage of printing ink on the display module assembly more continuous promptly to make the printing ink on the display module assembly more even.
In addition, the bezel assembly 20 is made of the same material as the display module.

Wherein, two sets of fixed frames 22 are arranged vertically and combined to form an L-shaped structure. The two groups of movable frames 21 are perpendicular to each other and are constructed to form another L-shaped structure, and the two L-shaped structures enclose each other to form a loading slot 30 for bearing a square structure of the display module. Through controlling two sets of movable frames 21 to move relative to the substrate 10 along two mutually perpendicular directions respectively, the size of the loading space of the loading slot 30 is changed, and the size of the display module can be better matched.
