As shown in fig. 1, a display device 10 according to an embodiment of the present invention includes a curved display panel 101, a backlight module 102, a buffer layer 103, and a frame 104.
The curved display panel 101 has an arc-shaped convex surface 1011; the curved display panel 101 is formed by bending glass, and has an arc convex surface 1011 on one side and a concave surface on the other side.
The backlight module 102 is disposed on the arc-shaped convex surface 1011 of the curved display panel 101, and a gap 105 is formed between the backlight module 102 and the curved display panel 101.
The backlight module 102 is a light emitting side near the arc-shaped convex surface 1011. The backlight module 102 is configured to provide a backlight source for the curved display panel 101, so that the display device 10 can display a picture.
The buffer layer 103 is disposed in the gap 105 filled between the curved display panel 101 and the backlight module 102. The buffer layer 103 is made of plastic or fiber reinforced plastic.
The elastic modulus of the buffer layer 103 is 30-70 GPa, preferably 50GPa, and can be 40GPa or 60 GPa.
At the sides of the curved display panel 101 and the backlight module 102, one side of the backlight module 102 facing the curved display panel 101 is attached to the arc-shaped convex surface 1011, and the widths of the gaps 105 are sequentially reduced from the center of the curved display panel 101 to the sides thereof; that is, the buffer layer 103 has a thickness distribution characterized by a thicker middle portion and thinner side portions.
Since the stress is greatest near the edges at the middle of the curved display panel 101 when it is bent, chipping is likely to occur. The material properties of the curved display panel 101 itself, the compressive strength is much greater than the tensile strength. According to the neutral layer theory, when the curved display panel 101 is bent, the outer layer is under tension, and the inner layer is under compression. The glass breakage generally occurs due to the tension of the outer glass at the edges of its central location.
In this embodiment, a method of adhering or coating a buffer layer 103 with different thickness on the curved display panel 101 is proposed, that is, the buffer layer 103 is filled in the gap 105 between the curved display panel 101 and the backlight module 102.
The elastic modulus of the buffer layer 103 is close to that of the curved display panel 101, and the buffer layer 103 has a thicker middle part and thinner two sides. The thickness of the buffer layer 103 is the largest at the position of the curved display panel 101 where the bending stress is the largest.
Therefore, after the curved-surface display panel 101 is bent inwards, the buffer layer 103 is pulled, and the curved-surface display panel 101 at the middle position is only pressed, so that the curved-surface fragment problem is prevented due to the good compressive strength of the curved-surface display panel 101.
A first surface 1031 of the backlight module 102 facing the curved display panel 101 has a first curvature radius, and the arc-shaped convex surface 1011 has a second curvature radius, and the first curvature radius is smaller than the second curvature radius.
The curved display panel 101 and the backlight module 102 are assembled on the frame 104 at the sides; the frame 104 is used to fix the curved display panel 101 and the backlight module 102.
As shown in fig. 2, the backlight module is a direct type backlight module. The backlight module 102 includes a back plate 1021, a heat dissipation layer 1022, a direct-type backlight 1023, and an optical film 1024.
The heat dissipation layer 1022 is disposed on a side of the back plate 1021 facing the curved display panel; the material of the heat dissipation layer 1022 is aluminum extrusion.
The direct-type backlight 1023 is arranged on one side of the heat dissipation layer 1022 far away from the back plate 1021; the direct type backlight source 1023 is an LED lamp bead.
The optical film 1024 is disposed on a side of the backlight source away from the heat dissipation layer 1022. The optical film 1024 is a prism film, and is used to diffuse the light of the backlight source and improve the brightness of the backlight module.
In this embodiment, the method of adhering or coating the buffer layer 103 with different thickness on the curved display panel 101 of the backlight module 100 is to fill a buffer layer 103 in the gap 105 between the curved display panel 101 and the backlight module 102.
The elastic modulus of the buffer layer 103 is close to that of the curved display panel 101, and the buffer layer 103 has a thicker middle part and thinner two sides. The thickness of the buffer layer 103 is the largest at the position of the curved display panel 101 where the bending stress is the largest.
Therefore, after the curved-surface display panel 101 is bent inwards, the buffer layer 103 is pulled, and the curved-surface display panel 101 at the middle position is only pressed, so that the curved-surface fragment problem is prevented due to the good compressive strength of the curved-surface display panel 101.
Since the stress is greatest near the edges at the middle of the curved display panel 101 when it is bent, chipping is likely to occur. The material properties of the curved display panel 101 itself, the compressive strength is much greater than the tensile strength. According to the neutral layer theory, when the curved display panel 101 is bent, the outer layer is under tension, and the inner layer is under compression. The glass breakage generally occurs due to the tension of the outer glass at the edges of its central location.
As shown in fig. 3, the present invention further provides a display device according to another embodiment, which is different from the first embodiment in that the backlight module 102a is a side-in type backlight module; the side-in backlight module includes a light guide plate 1021a, a side-in backlight 1022a, and a diffusion sheet 1023 a.
The side-in backlight 1022a is disposed at a side of the light guide plate 1021a, and the light guide plate 1021a is used for uniformly distributing light of the side-in backlight 1022 a.
The diffusion sheet 1023a is disposed on one side of the light guide plate 1021a facing the curved display panel to diffuse the backlight light and improve the brightness of the backlight module 102 a.
According to the invention, by providing the method for sticking or coating the buffer layer 103 on the curved-surface display panel 101, the problem of curved-surface fragment is solved, the reliability of the display device 10 is improved, the user experience quality is improved, the operation is simple and convenient, the effect is large, and long-term economic benefits are brought.
The elastic modulus of the buffer layer 103 is close to that of the curved display panel 101, and the buffer layer 103 has a thicker middle part and thinner two sides. The thickness of the buffer layer 103 is the largest at the position of the curved display panel 101 where the bending stress is the largest.
Therefore, after the curved-surface display panel 101 is bent inwards, the buffer layer 103 is pulled, and the curved-surface display panel 101 at the middle position is only pressed, so that the curved-surface fragment problem is prevented due to the good compressive strength of the curved-surface display panel 101.
The above examples are intended to be illustrative of the invention and are not intended to be limiting. In conclusion, the scope of the present invention should include those changes or substitutions and modifications which are obvious to those of ordinary skill in the art.
