Referring to fig. 2, in an embodiment of the present disclosure, the display device includes a display module 100, a backlight module 200, and a light shielding layer 300. The display module 100 has a display side 100a and a non-display side 100b opposite to each other along a first direction X, the backlight module 200 is stacked on the non-display side 100b of the display module 100 along the first direction X, the backlight module 200 has a side 200a perpendicular to the first direction X, and the light shielding layer 300 covers an edge of the display module 100 and is bent from a surface of the display side 100a of the display module 100 to extend to the side 200a of the backlight module 200.
In the display device provided in the embodiment of the application, the light shielding layer 300 is disposed at the edge of the display module 100, and the light shielding layer 300 is bent from the surface of the display side 100a of the display module 100 to extend to the side 200a of the backlight module 200, so that the gap between the display module 100 and the backlight module 200 is covered by the light shielding layer 300, thereby preventing light from leaking from the gap between the display module 100 and the backlight module 200, and thus, even if the gap between the display module 100 and the backlight module 200 is increased due to the deformation of the display module 100, the light shielding layer 300 can also effectively prevent light from leaking from the gap between the display module 100 and the backlight module 200. Therefore, when the display device is a narrow-frame display device, the light shielding layer 300 can still effectively shield light, thereby solving the problem that the narrow-frame display device is easy to leak light.
In some embodiments, the display device further includes a protection layer 400, the protection layer 400 is located on a surface of the light shielding layer 300 opposite to the display module 100, and the protection layer 400 completely covers the light shielding layer 300 and extends to the side 200a of the backlight module 200. Through set up protective layer 400 at a side surface that light shield layer 300 dorsad display module assembly 100 and backlight unit 200, cover protective layer 400 light shield layer 300 completely for light shield layer 300 obtains the protection, thereby avoids light shield layer 300 to damage, with the good effect of shading of guarantee light shield layer 300.

It can be understood that, at the side 200a of the backlight module 200, the larger the sum of the thickness of the light shielding layer 300 and the thickness of the protection layer 400 is, the wider the frame of the display device is. Based on this, in the embodiment of the present application, the sum of the thickness of the light-shielding layer 300 and the thickness of the protection layer 400 is set to be less than or equal to 0.1mm, so as to reduce the influence of the light-shielding layer 300 and the protection layer 400 on the frame width of the display device.
In addition, the sizes of the display module 100 and the backlight module 200 also affect the width of the frame of the display device, and therefore, in some embodiments, the sizes of the display module 100 and the backlight module 200 are limited, specifically, the difference between the widths of the display module 100 and the backlight module 200 in a second direction is less than or equal to 0.25mm, wherein the second direction Y is perpendicular to the first direction X, and the second direction Y is perpendicular to the side 200a of the backlight module 200, so as to ensure that the frame of the display module 100 is narrower.

Further, the thickness of the light-shielding layer 300 is less than or equal to 0.02 mm. It can be understood that, since the light-shielding layer 300 is bent and extended from the surface of the display side 100a of the display module 100 to the side surface 200a of the backlight module 200, the thickness of the light-shielding layer 300 affects the thickness of the display device and the width of the frame. Based on this, in the embodiment of the present application, the thickness of the light-shielding layer 300 is set to be less than or equal to 0.02mm, so as to ensure that the display device realizes an ultra-thin and ultra-narrow frame.
In some embodiments, the thickness of the first sublayer is less than or equal to 0.005 mm. When the thickness of the light-shielding layer 300 is determined and the light-shielding layer 300 is formed by laminating a plurality of sub-layers, the smaller the thickness of each sub-layer is, the more chance the sub-layers can make up the leaks of the rest of sub-layers, so that the light-shielding layer 300 achieves a good light-shielding effect. The thickness of the first sub-layer is smaller than or equal to 0.005mm, so that the shading effect is guaranteed. Similarly, the thickness of the second sub-layer can be set to be less than or equal to 0.005mm to ensure the shading effect. The thickness of the light-shielding layer 300, the thickness of the first sub-layer, and the thickness of the second sub-layer may satisfy the above conditions at the same time, or one or two of them may satisfy the above conditions.
In some embodiments, light absorbing particles 410 are disposed within the protective layer 400. Since the light absorbing particles 410 in the protection layer 400 have a light absorbing effect, the thickness of the light shielding layer 300 may be reduced accordingly based on this. For example, in an embodiment, the light absorbing particles 410 are disposed in the protection layer 400, and the thickness of the light shielding layer 300 is less than or equal to 0.01mm, so that the thickness of the light shielding layer 300 on the surface of the display side 100a of the display module 100 is smaller, and the display device is thinner, and meanwhile, the thickness of the light shielding layer 300 on the side 200a of the backlight module 200 is smaller, which is beneficial for realizing a narrow bezel.
In some embodiments, the light shielding layer 300 includes a conductive ink. The effect of electrostatic discharge is achieved through the conductive ink, so that the electrostatic effect at the edge of the display device is reduced while the good light shielding effect is achieved by using the light shielding layer 300, and the use experience of a user is improved.
In some embodiments, an adhesive layer 500 is disposed between the display module 100 and the backlight module 200 to adhere the edge of the display module 100 to the edge of the backlight module 200, and the edge of the adhesive layer 500 extends to contact with the light shielding layer 300. Because the adhesive layer 500 fills the gap between the display module 100 and the backlight module 200, and the edge of the adhesive layer 500 extends to contact with the light shielding layer 300, the adhesive layer 500 plays a supporting role in the middle of the process that the light shielding layer 300 bends from the surface of the display side 100a of the display module 100 to extend to the side 200a of the backlight module 200, and the light shielding layer 300 can be effectively prevented from cracking at the gap between the display module 100 and the backlight module 200.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
