Referring to fig. 1 to 3, fig. 1 is a schematic perspective view of an electronic device according to an embodiment of the present disclosure; FIG. 2 is a partial sectional view taken along line II-II of FIG. 1; fig. 3 is a schematic diagram of a partial front structure of the electronic device in fig. 1. The electronic device 100 in one embodiment of the present application includes a housing 20 and a display device 30 disposed on the housing 20. The housing 20 includes a middle frame 21 and a hinge 25, the middle frame 21 includes a first frame and a second frame, and the hinge 25 is connected between the first frame and the second frame. The display device 30 includes a display screen 34 and a glue 36, the display screen 34 includes a screen body 342, the screen body 342 includes a display surface, a back surface opposite to the display surface, and a side surface 3421 located between the display surface and the back surface. The colloid 36 is disposed on the side 3421 of the screen 342. In this embodiment, the gel 36 is an elastic gel, and therefore, the gel 36 is used to compensate for the tolerance of the length of the screen 342. Specifically, the display screen 34 further includes a cover plate 344 disposed on the display surface of the screen body 342. The end of the cover 344 extends out of the side 3421 of the screen 342, and a gap 37 is defined between the portion of the cover 344 extending out of the side 3421 of the screen 342 and the side 3421 of the screen 342. The gel 36 is disposed in the gap 37. That is, the gel 36 is filled in the gap 37, and the cured gel 36 has elastic energy for absorbing assembly tolerance. The display screen 34 is provided with a bendable region 345 corresponding to the hinge 25, and two non-bendable regions 347 on opposite sides of the bendable region 345. The back of the bendable region 345 is attached to the hinge 25, and two non-bendable regions 347 are disposed on the first frame and the second frame, respectively. Because the cured adhesive 36 has a large elasticity, tolerance can be absorbed when the display device 30 is mounted on the housing 20, and the display device 30 is conveniently mounted on the housing 20.
The front surface of the screen body 342 refers to the display surface of the screen body 342, and the back surface of the screen body 342 refers to the surface facing away from the display surface; the front surface of the gel 36 refers to the surface adjacent to the display surface of the screen 342, and the back surface of the gel 36 refers to the surface facing away from the display surface of the screen 342.
In this embodiment, the electronic device 100 is, for example, but not limited to, a mobile phone, a tablet computer, a display, a liquid crystal panel, an OLED panel, a television, a smart watch, a VR head-mounted display, a vehicle-mounted display, and any other products and components with display functions. The display device 30 is a flexible display device, and the screen 342 is a flexible screen.
The side 3421 of the screen 342 of the display device 30 of the electronic device 100 of the present application is provided with the gel 36, and the cured gel 36 has a large elasticity. Therefore, when the display device 30 provided with the gel 36 is mounted on the middle frame 21 of the housing 20, the gel 36 can effectively absorb the tolerance to facilitate the mounting of the display device 30 to the housing 20, and the gel 36 can prevent the problem of the sinking or collapsing due to the existence of the gap.
The gap 37 extends along the length direction of the side surface 3421 of the screen 342, and the colloid 36 is a strip-shaped colloid filled in the gap 37. When the display device 30 is mounted on the middle frame 21 of the housing 20, the glue 36 elastically abuts against the end wall of the middle frame 21, so that tolerance can be absorbed.
In this embodiment, the cover plate 344 is a light-transmitting film layer, and the cover plate 344 covers the screen body 342 and the encapsulant 36. The glue 36 is a transparent material, and external light can enter the lower portion of the glue 36 through the cover plate 344 and the glue 36. Specifically, the colloid 36 is a transparent photosensitive adhesive, that is, the colloid 36 is cured into an elastic and transparent solid adhesive by ultraviolet irradiation. External light can enter the housing 20 through the cover plate 344 and the gel 36. Specifically, the light transmittance of the colloid 36 is more than 90%.
In other embodiments, the elastic glue 36 may be a transparent optical glue. The cover plate 344 is a thin, light-transmissive, and bendable sheet, and in this embodiment, the cover plate 344 is an ultra-thin cover glass having a thickness of a micrometer.
The reason why the ultra-thin cover glass is used as the cover plate 344 in this embodiment is that the ultra-thin cover glass has the advantages of better bending resistance, high strength, high hardness, etc., and when the ultra-thin cover glass is attached to the display surface of the screen body 342, the ultra-thin cover glass can not only bend or flatten along with the screen body 342, but also can effectively resist the scratch of the screen body 342 caused by external objects, and is not easy to wear. Secondly, the elastic modulus of the ultra-thin cover glass is low, and the ultra-thin cover glass can be directly adhered to the display surface of the screen body 342, and can be synchronously or approximately synchronously stretched along with the screen body 342 when the display device 30 is bent, so that the situation that the display device 30 is damaged due to large difference of stretching amplitude when the display device is bent is avoided. On the other hand, the luminousness of ultra-thin glass cover plate is high, and is convenient the ejection of the light of the screen body 342, and after long-time use, ageing problems such as discolouration also can not appear in the ultra-thin glass cover plate.
In other embodiments, the cover 344 may also be a flexible transparent cover.
The reason why the cover plate 344 extends beyond the screen body 342 in this embodiment is to make the display 34 of the electronic device 100 have an integrated appearance, that is, since the cover plate 344 completely covers the screen body 342, no obvious visible step difference appears from the outside. In addition, the cover plate 344 further extends beyond the screen body 342 to be close to or abut against the end wall of the middle frame 21, so that the user can keep touch continuity when touching on the cover plate 344, no obvious tactile step difference occurs, and the touch experience is improved.
As shown in fig. 3, the glue 36 of the display device 30 is located inside the middle frame 21 and abuts against the end wall of the middle frame 21. A photosensitive element 212 is disposed on the back of the middle frame 21 opposite to the colloid 36, that is, the photosensitive element 212 is disposed below the colloid 36. Since the cover plate 344 and the encapsulant 36 are transparent, ambient light can pass through the cover plate 344 and the encapsulant 36 to be incident on the photosensitive element 212, that is, ambient light entering below the encapsulant 36 is incident on the photosensitive element 212. The light sensing element 212 sends a signal to a controller on a motherboard of the electronic device 100, and the controller receives the signal and controls the display brightness of the screen body 342.
In other embodiments, the colloid 36 has a light hole corresponding to the photosensitive element 212, and the colloid 36 in this embodiment may be non-transparent. Ambient light can penetrate through the cover plate 344 and the light holes on the colloid 36 to be incident on the photosensitive element 212, the photosensitive element 212 sends a signal to a controller on a main board of the electronic device 100, and the controller receives the signal and controls the display brightness of the screen 342.
In other embodiments, the back surface of the colloid 36 has a receiving hole corresponding to the photosensitive element 212, and the receiving hole is used for receiving the photosensitive element 212. Because the photosensitive element 212 is accommodated in the accommodating hole of the colloid 36, the photosensitive element 212 occupies less internal space of the middle frame 21, thereby facilitating the layout of other elements in the middle frame 21.
Referring to fig. 4 to 8, fig. 4 to 8 are schematic views illustrating a manufacturing process of the display device of the electronic device in fig. 1. The colloid 36 of the electronic device 100 of the present application is disposed in the gap 37 through a molding process, and the colloid 36 is positioned by using a molding positioning mechanism 50 in the molding process.

The positioning frame 52 includes a positioning plate parallel to the side surface 3421 of the panel 342, the length of the positioning plate is equal to the length of the side surface 3421 of the panel 342, and the positioning frame 52 is used for positioning the display 34. The positioning frame 52, the portion of the cover plate 344 extending out of the side surface 3421 of the screen body 342, and the side surface 3421 of the screen body 342 enclose the gap 37, and the pressing plate 54 is used for flattening the glue 36 in the gap 37. The weight 56 is arranged on the side of the pressure plate 54 facing away from the gap 37.
