DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0026] In order to illustrate a technical solution according to embodiments of the disclosure more clearly, drawings to be used in the description of the embodiments will be briefly set forth in the following. It is obvious that the drawings in the following description are only related to some embodiments of the disclosure. Those ordinarily skilled in the art may obtain other embodiments according to these drawings, without any inventive work.

[0027] As shown in FIG. 1 to FIG. 3, are schematic views of a display device according to an embodiment of the disclosure. In this embodiment, the display device 1 could be liquid crystal display, liquid crystal television, mobile phone or tablet and so on. The display device 1 includes a display module 100. The display module 100 includes a flexible display panel 103, a cover 101 disposed on the flexible display panel 103 and a transparent glue 102 disposed between the flexible display panel 103 and the cover 101. In this embodiment, the flexible display panel 103 is a display panel made of organic light emitting diodes. In other embodiment, the flexible display panel 103 could be a liquid crystal display panel and so on. The flexible display panel 103 and the cover 101 include a bending portion 104 and a non-bending portion 105. In this embodiment, the bending portion 104 is defined as a bendable part, a radius of the bending portion 104 is R and a length of the bending portion 104 is ?R in the bending state, and a length of the non-bending portion 105 is between ?R+5 and ?R+10. The transparent glue 102 inside the bending portion 104 is not cured, so the transparent glue 102 of the display module 100 has better fluidity when bending along the bending portion 104. The transparent glue 102 inside the non-bending portion 105 is not cured, so the display module 100 has better adhesion performance in the non-bending portion 105. Therefore, the display module bending failure and non-recoverable deformation problems could be solved.

[0028] In this embodiment, the flexible display panel 103 and the cover 101 are bending along a middle position, so the bending portion 104 is the middle position of the flexible display panel 103 and the cover 101, the non-bending portion 105 is located at two sides of the bending portion 104. In other embodiment, the flexible display panel 103 and the cover 101 could bend along a predetermined position, so the bending portion 104 and the non-bending portion 105 could be correspondingly disposed according to the predetermined position.

[0029] As shown in FIG. 4, a coating glue method of a display module provided by the disclosure, including the following steps:

[0030] Step S401, coating a transparent glue 102 in a non-cured state between the flexible display panel 103 and the cover 101. In this embodiment, a material of the transparent glue 102 is one or a combination of acrylic, silicon, polyurethane and rubber.

[0031] Step S402, using a blocking curing material to cover the bending portion 104 and the transparent glue 102 inside the bending portion 104.

[0032] Step S403, curing the transparent glue 102 inside the non-bending portion 105. In this embodiment, the blocking curing material is an ultraviolet blocking material, the step of curing the transparent glue 102 inside the non-bending portion 105 specifically is: performing an ultraviolet curing method to cure the transparent glue 102 inside the non-bending portion 105. In other embodiment, the blocking curing material could be other material depending on the curing method, other curing method such as moisture curing, heat curing, anaerobic curing and double curing and so on.

[0033] Furthermore, the coating glue method of the display module further includes the following steps: removing the blocking curing material on the bending portion 104 after curing the transparent glue 102 inside the non-bending portion 105.

[0034] In the display device and the display module provided by the disclosure, the transparent glue inside the bending portion is not cured, and the transparent glue inside the non-bending portion is not cured, so the display module bending failure and non-recoverable deformation problems could be solved.

[0035] The foregoing contents are detailed description of the disclosure in conjunction with specific preferred embodiments and concrete embodiments of the disclosure are not limited to these descriptions. For the person skilled in the art of the disclosure, without departing from the concept of the disclosure, simple deductions or substitutions can be made and should be included in the protection scope of the application.
