Since the cover plate 201 may be made of rigid glass, after the polarizing layer 202, the substrate 203 and the bottom plate 204 are connected to the cover plate 201, the side edges thereof also form arc-shaped edges, and the surfaces of the layers may decrease gradually in the direction from the cover plate 201 to the bottom plate 204, so that a step structure is formed between the adjacent layers.

Wherein the waterproof film layer covers at least the side wall of the polarizing layer 202; in one example, the waterproof film layer covers at least one sidewall in the length direction and two sidewalls in the width direction of the polarizing layer 202, because the other sidewall in the length direction of the polarizing layer is needed for connection with the LPC bus, thereby enabling connection with the display driver and the terminal main board.

The cross-linked polymer adhesive (MS adhesive) based on the silane-terminated polyether has simple curing conditions and obvious waterproof effect after curing.

In a second aspect, at least one embodiment of the present disclosure provides a jig for manufacturing the display module according to the first aspect, please refer to fig. 5, which shows a structure of the jig, including a jig body 501 and a jig cover 502, which are rotatably connected, wherein the jig body 501 is provided with a jig slot 5011 for placing the display module, and the jig cover 502 is provided with a jig hole 5021 matched with the jig slot 5011.

Wherein, the jig body 501 and the jig cover 502 are connected by at least one rotating connector 503 (e.g. a hinge); the jig hole 5021 can be the same as the jig slot 5011 in size, that is, the projection of the jig hole 5021 on the jig body 501 completely coincides with the bottom of the jig slot 5011, so that the display module monomer in the jig slot 5011 can be completely exposed after the jig cover 502 is closed; the jig hole 5021 can also be smaller than the jig slot 5011, that is, the projection of the jig hole 5021 on the jig body 501 falls into the jig slot 5011, but cannot completely cover the bottom of the jig slot 5011, so that after the jig cover 502 is closed, part of the edge of the display module monomer in the jig slot 5011 is shielded, and the rest is in an exposed state; each edge of the jig hole 5021 can be completely symmetrical or asymmetrical, and is specifically designed according to the manufacturing requirements of the display module.

Referring to fig. 6, in an example, a shielding plate 603 is disposed in the jig hole 602 of the jig cover 601, wherein the shielding plate 603 is disposed on one side of the jig hole 602 in the length direction. The shielding part 603 can be matched with the manufacturing requirement of the display module, so that the waterproof film layer can be selectively manufactured on part of the side wall. The position of the shielding portion 603 shown in fig. 6 is suitable for manufacturing a waterproof module on two width-direction side walls and one length-direction side wall of the display module unit, and of course, the shielding portion 603 can be arranged at other positions according to the manufacturing requirement of the display module, and the disclosure does not intend to limit the arrangement position and number of the shielding portion 603.

In a third aspect, at least one embodiment of the present disclosure provides a manufacturing method of a display module, for manufacturing the display module described in the first aspect, please refer to fig. 7, which schematically illustrates a flow of the manufacturing method, including steps S701 to S702.

In step S701, a display module unit is manufactured.

In this step, can connect each layering of display module assembly monomer, for example with bottom plate, base plate, polarisation layer and apron carry out the laminating connection according to predetermineeing the order, wherein, can adopt connecting medium to connect between bottom plate, base plate, polarisation layer and the apron, connecting medium can select photoresist, photosensitive glue or glass melting glue etc..

In one example, referring to fig. 8, first, the substrate is attached to the polarization layer 805, so that the touch layer 804 of the substrate is connected to the polarization layer 805 (in addition, the polyimide layer 801, the organic light emitting device layer 802, the encapsulation layer 803, and the touch layer 804 of the substrate and the organic light emitting device layer 802 further include an array sub-layer 8021 and an organic sub-layer 8022, which are completely the same as the above structure shown in fig. 3, in fig. 8); referring to fig. 9, next, the substrate is attached to the bottom plate 906, so that the polyimide layer 901 of the substrate is connected to the bottom plate 906 (in addition, the polyimide layer 901, the organic light emitting device layer 902, the encapsulation layer 903, the touch layer 904, the polarization layer 905, and the organic light emitting device layer 902 of the substrate shown in fig. 9 further include an array sub-layer 9021 and an organic sub-layer 9022 which are identical to the above-mentioned structures shown in fig. 8); referring to fig. 10, finally, a side of the polarization layer 1005 away from the substrate is connected to the cover plate 1007 (in addition, the polyimide layer 1001, the organic light emitting device layer 1002, the encapsulation layer 1003, the touch layer 1004, the polarization layer 1005, the bottom plate 1006, and the organic light emitting device layer 1002 of the substrate shown in fig. 10 further include an array sub-layer 10021 and an organic sub-layer 10022 which are identical to the above structure shown in fig. 9).

In step S702, a waterproof film layer is formed on at least one sidewall of the display module unit.

The waterproof requirements of all layers of the display module are different, the individual layer is greatly influenced by moisture, and the individual layer is less influenced by moisture and even not influenced by moisture. In bottom plate, base plate, polarisation layer and apron, the polarisation layer is influenced by the moisture greatly, and moisture such as sweat very easily enters into the polarisation in situ through the lateral wall on polarisation layer to influence whole display module's display performance.

After the display module is installed on the terminal equipment, due to the influence of the installation position, the waterproof requirements of all the side walls are different, the influence of moisture on individual side walls is large, the waterproof requirements are high, the influence of hand moisture on individual side walls is small, and even the influence of moisture is avoided. Therefore, the side wall of the waterproof membrane layer can be determined according to the waterproof requirement of each side wall.

In one example, the waterproof film layer covers at least one side wall of the polarizing layer, that is, in each layer of the display module, the waterproof film layer is manufactured on at least one side wall of the polarizing layer.

In the embodiment of this disclosure, through preparation display module assembly monomer and make waterproof rete on display module assembly monomer at least one lateral wall, can increase the waterproof performance of display module assembly's lateral wall, avoid moisture such as sweat to enter into display module assembly through the lateral wall in, and then avoid moisture to influence display module assembly's display function, improve terminal equipment's use and experience.

In some embodiments of the present disclosure, a waterproof film layer may be fabricated on at least one sidewall of the display module unit in a manner as shown in fig. 11, specifically including steps S1101 to S1103.

In step S1101, a display module unit is disposed in the fixture according to the second aspect, such that at least one sidewall of the polarizing layer is exposed.

In one example, the display module single body may be first placed in the jig groove, so that the outer surface of the display module single body is connected with the bottom of the jig groove; and then, closing the jig groove by using the jig cover body so as to partially or completely shield each side wall of the display module monomer and enable at least one side wall of the polarizing layer to be in an exposed state. When the display module single body is placed, the outer surface of the cover body is connected with the bottom of the jig groove, namely, the side edges of the cover body, the polarizing layer, the substrate and the bottom plate form arc-shaped edges bent towards the inner surface, namely the side walls face the opening direction of the jig groove; when the free lateral wall of display module assembly is sheltered from to the tool lid, can shelter from entirely, the lateral wall that also is lid, polarisation layer, base plate and bottom plate is all sheltered from, also can be partly shelters from, also the lateral wall of lid is sheltered from exactly, and the lateral wall of polarisation layer, base plate and bottom plate all is in the exposure state.

For example, a waterproof film layer may be formed on one sidewall in the length direction and both sidewalls in the width direction of the polarizing layer, and thus the jig cover may be configured as shown in fig. 5 and 6. When the display module group monomer is placed in the jig groove and the jig groove is closed by the jig cover body, one side wall of the length direction of the display module group monomer is completely shielded, namely, the side wall of one length direction of the polarizing layer is shielded, and a waterproof film layer is prevented from being manufactured on the side wall. The area of the jig hole is smaller than the area of the jig groove, so that the jig cover can partially shield the side wall of the display module unit, specifically referring to fig. 12, which shows the positional relationship among the display module unit, the jig body, and the jig cover. As can be seen from fig. 12, the side edges of the cover plate 1201, the polarizing layer 1202, the substrate 1203 and the bottom plate 1204 of the display module monomer placed in the jig groove of the jig body 1205 all form arc-shaped edges curved toward the inner surface, the jig cover 1206 closes the jig groove of the jig body 1205, the edge of the jig hole of the jig cover 1206 extends into the range of the jig groove, partially blocks the side wall of the display module monomer, specifically, blocks the side wall and the inner surface of the cover plate 1201 (i.e., the inner surface of the cover plate 1201 at the step formed by the cover plate 1201 and the polarizing layer 1202), and the side wall of the polarizing layer 1202 is exposed. This not only is convenient for make waterproof rete to the lateral wall of polarisation layer 1202, can also avoid making waterproof rete at the lateral wall of apron 1201 and internal surface, because the lateral wall and the internal surface of apron 1201 all are equipped with printing ink, and when installing display module assembly in terminal equipment moreover, the printing ink area of apron is used for scribbling the connecting medium (for example PUA glue) of being connected with terminal equipment's center, consequently avoids influencing subsequent mounting process because of printing ink is covered by waterproof rete.

The inner surface of the display module monomer can be provided with a protective film, and specifically, the protective film can be release paper. Through setting up the protection film, can avoid making waterproof rete at the free internal surface of display module assembly (specifically the internal surface of bottom plate 1204) to avoid influencing display module assembly's subsequent processing technology and its inherent function.

In step S1102, the waterproof adhesive is uniformly coated on at least one sidewall of the polarizing layer by using a glue spraying process or a coating process.

Wherein, the waterproof glue can be covered on the side wall by adopting a vacuum coating mode.

When the glue spraying process is adopted, the operation parameters of the glue spraying equipment can be debugged firstly, so that the glue spraying equipment can spray a glue layer with preset thickness, the glue layer can be sprayed on a test plane, the thickness of the glue layer is detected, and the glue layer is continuously adjusted until the preset requirement is met. In one example, the atomization air pressure of the glue spraying device can be set to be 0.55MPa, the glue feeding air pressure can be set to be 0.3MPa, and the spraying speed can be set to be 60 mm/s; the inner diameter of a glue spraying head of the glue spraying equipment is 0.34 mm.

In one example, a cross-linked polymer glue based on silane terminated polyether (MS glue) may be selected as the water-repellent glue, and specifically a mezzanine 3995 modified silane glue may be used.

In step S1103, the waterproof glue is cured to form a waterproof film layer.

Wherein, the waterproof glue can be solidified by heating, standing and the like. In one example, the waterproof glue may be left to stand for 24 hours to complete the curing of the waterproof glue.

In the embodiment of this disclosure, fix the display module assembly monomer through the tool to combine the protection film to shelter from the position that need not to make waterproof rete among the display module assembly monomer, only expose the position that needs the waterproof rete of preparation of display module assembly monomer, improved the preparation accuracy of waterproof rete, avoided waterproof rete to influence the follow-up technology and the inherent function of display module assembly simultaneously.

According to the display module manufactured by the manufacturing method provided by the embodiment of the disclosure, the waterproof film layer is manufactured on the side wall of the polarizing layer, so that the display module can pass a sweat resistance test standard of 144 hours.

In a fourth aspect, at least one embodiment of the present disclosure provides a terminal device, including a middle frame and the display module of any one of the first aspect; the middle frame comprises a frame and a front shell, and the inner surface of the display module is fixedly connected with the front shell.

In one embodiment, no waterproof glue is arranged between the display module monomer and the frame.

Referring to fig. 13, in the related art, when the display module is connected to the middle frame, the cover plate 1301 and the frame 1302 of the middle frame need to be hermetically connected (i.e., the cover plate 1302 and the cover plate 1301 are bonded by the waterproof adhesive 1303 to complete the connection and waterproof processing at the same time), so that a width for bonding needs to be reserved on the cover plate 1301, the edge of the cover plate 1302 protrudes from the black border region 1304 of other layers of the display module, and the width for bonding increases the width of the black border region 1304, which affects the display effect of the display module, and increases the width of the frame in the visual effect.

Referring to fig. 14, in this embodiment, the inner surface of the display module is directly and fixedly connected to the front shell 1403 of the middle frame, for example, the display module is bonded by using a glue 1405, so that the connection between the display module and the middle frame is completed, and the display module itself is subjected to waterproof sealing treatment, so that the space between the side frame 1402 and the cover plate 1401 does not need to be sealed (i.e., a waterproof glue does not need to be arranged between the side frame 1402 and the cover plate 1401), thereby avoiding the width reserved on the cover plate 1401 for bonding, further reducing the black edge area 1404, improving the display effect, and reducing the width of the side frame in the visual effect, and achieving the technical effect of a narrow side frame.

In some examples, the waterproof film layer 1406 is disposed on all sidewalls of the single display module, so that waterproof sealing processing is not required between each sidewall of the display module and the frame 1402 of the middle frame, and thus the width of the black border region 1404 of each direction of the display module is reduced. In other embodiments, the waterproof film layer 1406 is disposed on a part of the side wall of the display module, waterproof sealing treatment is not required between the side wall on which the waterproof film layer 1406 is disposed and the corresponding frame 1402, therefore, the width of the black border region 1404 in the corresponding direction of the display module is reduced, and waterproof sealing treatment is required between the side wall without the waterproof film 1406 and the corresponding frame 1402, that is, the cover 1401 is required to be bonded and sealed with the frame 1402, the two ends of the side wall not provided with the waterproof film 1406 are also required to be sealed, that is, the cover plate 1401 and the front shell 1403 are bonded and sealed, that is, the communication between the side wall not provided with the waterproof film 1406 and the side wall provided with the waterproof film 1406 is cut off, in order to prevent moisture entering from a gap between the side wall on which the waterproof film layer 1406 is provided and the corresponding frame 1402 from affecting the side wall on which the waterproof film layer 1406 is not provided.

Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein.
