The coated region 1111 is coated with a transparent adhesive 14, and the transparent adhesive 14 is used to adhere the cover plate 12 covering the display surface 111 of the display module 11. The coated region 1111 constitutes a display region on the display surface 111 of the display module 11, and the non-coated region 1112 constitutes a non-display region on the display surface 111 of the display module 11.
It should be noted that the display surface of the electronic device generally includes a display area and a non-display area. Wherein, the display area of electronic equipment coincides with the display area of display module assembly, and electronic equipment's non-display area includes the edge of the non-display area of display module assembly and display module assembly to the region of electronic equipment frame. With the development of electronic equipment technology, the screen occupation ratio of the electronic equipment is required to be higher and higher by users, and the frame of the display screen of the electronic equipment is narrower. Generally, the non-display area on the display surface of the display module is made narrower. In the related art, the display screen with the width of the non-display area smaller than 0.7 mm on the display surface of the display module is called as a narrow-frame display screen, and the display screen assembly provided by the embodiment of the application is the narrow-frame display screen. Therefore, the width of the non-coated region 1112 is not more than a preset value of 0.7 mm. It is understood that the "predetermined value" should be a value that includes a machining tolerance, such as plus or minus 0.01mm (+ -0.01 mm), and the width of the non-coated region 1112 is no greater than 0.71 mm.
The display module 11 may have a rectangular plate-like structure, and the display surface 111 and the non-display surface 112 are both rectangular, the coating region 1111 is also rectangular, the non-coating region 1112 is a rectangular ring surrounding the coating region 1111, and the two are in a "return" shape on the display surface 111. The display module 11 may also be a circular plate-shaped structure, and the display surface 111 and the non-display surface 112 are both circular, the coating region 1111 is also circular, the non-coating region 1112 is an annular ring surrounding the periphery of the coating region 1111, and the two are concentric on the display surface 111. The display module 11 may also be a plate-shaped structure with other shapes, and the drawings in the embodiment of the present application take the display module 11 as a rectangular plate-shaped structure as an example, but the embodiment of the present application does not limit the specific shape of the display module 11.
The cover plate 12 covers the display module 11 to protect the display module 11 and prevent the display module 11 from being scratched or damaged by water. The cover 12 may be a transparent glass cover, so that a user can observe the contents displayed by the display module 11 through the cover 12. In some embodiments, the cover plate 12 may be a glass cover plate made of a material such as sapphire. It is understood that the cover 12 may be integrally formed with the display module 11.
The cover plate 12 may include a flat portion 121, the flat portion 121 being disposed to cover the display surface 111 of the display module 11, the flat portion 121 being bonded to the coating region 1111 while a first gap is formed between the flat portion 121 and the non-coating region 1112. Specifically, the flat portion 121 may include a first region 1211 and a second region 1212, wherein the second region 1212 is surrounded at a periphery of the first region 1211, the first region 1211 is adhered to the coating region 1111 of the display surface 111 of the display module 11 through the transparent adhesive 14 coated on the coating region 1111, and a first gap is formed between the second region 1212 and the non-coating region 1112 on the display surface 111 of the display module 11.

Referring to fig. 4, fig. 4 is another cross-sectional view taken along the direction P-P in fig. 1. The cover plate 12 may further include a bent portion 122. The bent portion 122 may be disposed at the periphery of the straight portion 121, for example, the bent portion 122 is connected to the periphery of the second region 1212 in a bent manner. When the flat portion 121 covers the display surface 111 of the display module 11, the projection of the display module 11 along the thickness direction of the display module 11 is entirely located on the flat portion 121, and the projection of the display module 11 along the width direction of the display module 11 is entirely located on the bending portion 122. The bending portion 122 may also be disposed on two sides of the flat portion 121, for example, two bending portions 122 are respectively connected to two sides of the second region 1212 in a bending manner. When flat portion 121 lid is established on display surface 111 of display module assembly 11, display module assembly 11 is located flat portion 121 on along the projection of 11 thickness directions of display module assembly, and display module assembly 11 is located on a kink 122 on left side or right side along the projection of 11 width directions of display module assembly. That is, the size of the flat portion 121 of the cover 12 is not smaller than the size of the display module 11, so that the flat portion 121 completely covers the display surface 111 of the display module 11; the free end of the bending portion 122 of the cover 12 protrudes out of the non-display surface 112 of the display module 11, so that the bending portion 122 completely covers the first side surface 113 of the display module 11. Meanwhile, a second gap is formed between the bending portion 122 of the cover 12 and the two first side surfaces 113 in the width direction of the display module 11, and the second gap is communicated with the first gap.
The backlight module 13 has a first surface 131, a second surface 132 and four second sides 133. The first surface 131 is opposite to the second surface 132, and the four second side surfaces 133 are connected between the first surface 131 and the second surface 132. The backlight module 13 is disposed on the display module 11, and light emitted from the backlight module 13 can be displayed through the display module 11. Specifically, the first surface 131 of the backlight module 13 is adhered to the non-display surface 112 of the display module 11. It can be understood that the first surface 131 of the backlight module 13 and the non-display surface 112 of the display module 11 can be connected in other manners, and the embodiment of the present application does not limit the specific connection manner between the backlight module 13 and the display module 11. Meanwhile, a third gap is formed between each of the two bending portions 122 of the cover 12 and the two second side surfaces 133 in the width direction of the backlight module 13, and the third gap is communicated with the second gap.
A layer of shading glue 15 is arranged in the first gap, the second gap and the third gap. Specifically, the light shielding glue 15 may be dispensed from the space between the ends of the two bending portions 122 and the two second side surfaces 133 in the width direction of the backlight module 13 by a dispensing device, so that the light shielding glue 15 sequentially fills the third gap, the second gap, and the first gap, but the embodiment of the present application is not limited to the specific manner of disposing the light shielding glue 15. The light-shielding glue 15 in the first gap is used for bonding the non-coating area 1112 on the display surface 111 of the display module 11 and the second area 1212 on the flat portion 121 of the cover plate 12, and the light-shielding glue 15 in the second gap is used for bonding the two bending portions 122 of the cover plate 12 and the two first side surfaces 113 in the width direction of the display module 11, and simultaneously prevents light emitted by the backlight module 13 arranged on the non-display surface 112 of the display module 11 from passing through the non-display area of the display module 11. The light-shielding glue 15 in the third gap is used to strengthen the connection between the backlight module 13 and the display module 11, and simultaneously bond the two bending portions 122 of the cover plate 12 and the two second side surfaces 133 in the width direction of the backlight module 13.
The four second side surfaces 133 of the backlight module 13 and the four first side surfaces 113 of the display module 11 may be all flush, so that the backlight module 13 is overlapped with the display module 11, and the third gap and the second gap have the same width. The four second side surfaces 133 of the backlight module 13 and the four first side surfaces 113 of the display module 11 may also be partially flush, the four second side surfaces 133 of the backlight module 13 and the four first side surfaces 113 of the display module 11 may also be completely non-flush, so that the backlight module 13 and the display module 11 are not overlapped, and the third gap and the second gap are not equal in width.
The display screen assembly provided by the embodiment of the application is characterized in that the display area of the display surface of the display module is coated with the transparent adhesive to bond the display module and the cover plate, the whole non-display surface of the display module is coated with the adhesive to bond the display module and the backlight module, a first gap between the non-display area of the display surface of the display module and the cover plate, a second gap between the side surface of the display module and the cover plate and a third gap between the side surface of the backlight module and the cover plate are internally provided with a layer of light shielding adhesive to strengthen the bonding of the backlight module, the display module and the cover plate prevent light from being transmitted out from the non-display area of the display module, the bonding strength between the display module and the backlight module as well as between the display module and the cover plate in the display screen assembly can be strengthened, and the problem of screen failure caused by the layering of the display screen assembly in the testing and using processes of electronic equipment is reduced; and meanwhile, only one layer of shading glue is arranged between the display module and the cover plate, so that the width of a non-display area of the display module can be reduced, and the display screen assembly has a narrower frame.
The embodiment of the application also provides an assembling method of the display screen assembly, which is applied to the assembling of the display screen assembly of the electronic equipment. Referring to fig. 5 to 8, fig. 5 is a flowchart of an assembly method of a display panel assembly according to an embodiment of the present disclosure, fig. 6 is a schematic structural diagram of a first state in an assembly process of the display panel assembly according to the embodiment of the present disclosure, fig. 7 is a schematic structural diagram of a second state in the assembly process of the display panel assembly according to the embodiment of the present disclosure, and fig. 8 is a schematic structural diagram of a third state in the assembly process of the display panel assembly according to the embodiment of the present disclosure.
