[0046] like Figure 1 and Figure 2 As shown, the display module includes a display panel 1, a support layer group 2, a driver chip 3, a flexible circuit board 4, a first adhesive layer 5, and a second adhesive layer 6. The support layer group 2 is provided on the non-light-emitting side of the back of the display panel 1. The first adhesive layer 5 and the second adhesive layer 6 are provided on the side of the support layer group 2 away from the display panel 1. The display panel 1 is bent to the side of the support layer group 2 away from the display panel 1 and is bonded to the first adhesive layer 5. The second adhesive layer 6 is provided on the side of the first adhesive layer 5 away from the bent portion of the display panel 1. The flexible circuit board 4 is bound to the display panel 1 and is bonded to the second adhesive layer 6. The display module also includes a polarizer 7 and a third adhesive layer 8. The polarizer 7 is provided on the display side of the display panel 1. The third adhesive layer 8 is provided on the side of the polarizer 7 away from the display panel 1. The cover plate 9 is bonded to the side of the third adhesive layer 8 away from the display panel 1.

[0047] Due to irresistible factors such as assembly tolerance and refraction of the material itself, light leakage will occur at the edge of the display module. In order to prevent light leakage from the edge of the display module, a shading portion 91 is provided on the side of the cover plate 9 close to the display panel 1. The shading portion 91 is located at the edge of the display panel 1, and the positive projection of the polarizer 7 on the display panel 1 overlaps with the positive projection of the shading portion 91 of the cover plate 9 on the display panel 1. Improving the screen-to-body ratio has always been a strong demand for the iteration of display modules, but after the narrow frame capability is improved to a certain extent, the distance between the display area 11 of the display panel 1 and the frame of the display module is further compressed, and the outgoing light of the display area 11 of the display panel 1 will be emitted from the edge of the polarizer 7 and the side of the shading portion 91 close to the display area 11, resulting in varying degrees of light leakage in the module at the polarizer 7 and the cover plate 9.

[0048] Based on this, the present disclosure provides a display module. Figures 3 to 19 As shown, the display module includes a display panel 1, a cover plate 9 and a polarizer 7. The display panel 1 has a display area 11. The cover plate 9 is arranged on the light-emitting side of the display panel 1. A shading portion 91 and a first anti-glare portion 92 are provided on a side of the cover plate 9 close to the display panel 1. The shading portion 91 and the first anti-glare portion 92 are arranged in sequence along the edge away from the cover plate 9. The positive projection of the first anti-glare portion 92 on the display panel 1 overlaps with the display area 11. A second anti-glare portion 93 is provided on the side of the cover plate 9, and the second anti-glare portion 93 is located on the reflected light path of the first anti-glare portion 92; the polarizer 7 is arranged between the display panel 1 and the cover plate 9, and a light absorption pattern 77 is provided on at least one side of the polarizer 7. The light absorption pattern 77 is arranged close to the edge of the polarizer 7, and the side of the light absorption pattern 77 close to the display area 11 is farther away from the display area 11 than the side of the shading portion 91 close to the display area 11.

[0049] The cover plate 9 has a first anti-glare portion 92 provided on one side near the display panel 1. The orthographic projection of the first anti-glare portion 92 on the display panel 1 overlaps with the display area 11. A second anti-glare portion 93 is provided on the side of the cover plate 9. The second anti-glare portion 93 is located in the reflection light path of the first anti-glare portion 92. A portion of the light emitted from the display area 11 is diffusely reflected by the first anti-glare portion 92, while another portion passes through the first anti-glare portion 92 and is incident on the second anti-glare portion 93, where it is diffusely reflected by the second anti-glare portion 93 and enters the human eye. This prevents the light emitted from the display area 11 from directly penetrating the human eye and creating the visual effect of light leakage from the edge of the cover plate 9. The edge of the polarizer 7 is provided with a light-absorbing pattern 77. Light from the display area 11 incident on the edge of the polarizer 7 is completely absorbed, preventing light leakage from the side of the polarizer 7. This can reduce the overlap distance between the polarizer 7 and the light-shielding portion 91, further improving the screen-to-body ratio of the display module.

[0050] It should be noted that Figures 3 to 19 The shape of the display module is circular, which is only an example and does not constitute a specific limitation. This solution is also applicable to display modules of other shapes, which are not listed here one by one.

[0051] The display module involved in the embodiment of the present disclosure is described in detail below with reference to specific embodiments.

[0052] like Figures 3 to 5As shown, the display module may include a display panel 1, a support layer group 2, a driver chip 3, a flexible circuit board 4, a first adhesive layer 5, and a second adhesive layer 6. The support layer group 2 is provided on the non-light-emitting side of the back of the display panel 1. The first adhesive layer 5 and the second adhesive layer 6 are provided on the side of the support layer group 2 away from the display panel 1. The display panel 1 is bent to the side of the support layer group 2 away from the display panel 1 and is bonded to the first adhesive layer 5. The second adhesive layer 6 is provided on the side of the first adhesive layer 5 away from the bent portion of the display panel 1. The flexible circuit board 4 is bound to the display panel 1 and is bonded to the second adhesive layer 6. The display module also includes a polarizer 7, a third adhesive layer 8, and a cover plate 9. The polarizer 7 is provided on the display side of the display panel 1, the third adhesive layer 8 is provided on the side of the polarizer 7 away from the display panel 1, and the cover plate 9 is bonded to the side of the third adhesive layer 8 away from the display panel 1.

[0053] A shading portion 91 and a first anti-glare portion 92 are provided on one side of the cover plate 9 close to the display panel 1. The shading portion 91 is adjacent to the first anti-glare portion 92. The shading portion 91 and the first anti-glare portion 92 are arranged in sequence along the edge away from the cover plate 9. A second anti-glare portion 93 is provided on the side of the cover plate 9. The second anti-glare portion 93 is located in the reflected light path of the first anti-glare portion 92.

[0054] A portion of the light emitted from the display area 11 is diffusely reflected by the first anti-glare portion 92, while another portion passes through the first anti-glare portion 92 and is incident on the second anti-glare portion 93, where it is diffusely reflected by the second anti-glare portion 93 and enters the human eye. This prevents the light emitted from the display area 11 from directly penetrating the human eye and thereby prevents the visual effect of light leakage from the edge of the cover plate 9. To ensure an effective anti-glare effect, the orthographic projection of the first anti-glare portion 92 on the display panel 1 overlaps with the display area 11. The width of the first anti-glare portion 92 can be set to 0.3 mm to 0.4 mm. In this embodiment, the width of the first anti-glare portion 92 can be set to 0.3 mm, 0.32 mm, 0.34 mm, 0.36 mm, or 0.4 mm.

[0055] like Figures 6 to 8 As shown, to prevent light diffusely reflected by the second anti-glare portion 93 from exiting through the side of the cover plate 9 away from the display panel 1, a third anti-glare portion 94 is provided on the side of the cover plate 9 away from the display panel 1. The third anti-glare portion 94 at least covers the reflected light path of the second anti-glare portion 93. In this embodiment, the third anti-glare portion 94 entirely covers the side of the cover plate 9 away from the display panel 1. Light incident on the second anti-glare portion 93 is diffusely reflected by the second anti-glare portion 93 to the third anti-glare portion 94, and then diffusely reflected by the third anti-glare portion 94 to the light shielding portion 91. The light shielding portion 91 absorbs the diffusely reflected light from the third anti-glare portion 94, completely preventing light emitted from the display area 11 from exiting through the edge of the cover plate 9 and entering the human eye.

[0056] It is understood that the first anti-glare portion 92, the second anti-glare portion 93, and the third anti-glare portion 94 can prevent light from transmitting. The first anti-glare portion 92, the second anti-glare portion 93, and the third anti-glare portion 94 are formed through an anti-glare (AG) process. The AG process is a special chemical process that transforms the original reflective surface of the glass into a matte diffuse reflective surface. This can blur the reflection, prevent glare, reduce reflectivity, and reduce light and shadow. The anti-glare product has a strong surface corrosion resistance and scratch resistance. One anti-glare process can be to directly etch a rough texture on the surface of the cover plate 9, and another can be to coat the surface of the cover plate 9 with a rough film.

[0057] In this embodiment, an anti-glare (AG) process is added compared to the conventional cover plate 9 processing flow. The specific process is as follows: obtain a whole cover plate 9 substrate, cut the whole cover plate 9 substrate into multiple cover plates 9 according to the required size, clean and remove burrs and dirt on the surface of the cover plate 9, polish to further reduce the roughness of the surface of the cover plate 9, perform chemical strengthening treatment on the polished cover plate 9, form a shading portion 91 on the side of the cover plate 9 close to the display panel 1 through screen printing technology, form a first anti-glare portion 92 on the area of ​​the cover plate 9 located inside the shading portion 91 through an anti-glare process, and form a second anti-glare portion 93 on the side of the cover plate 9. When the cover plate 9 adopts Figures 6 to 8 When the structure of the display module is shown in the figure, a third anti-glare portion 94 may be formed on the side of the cover plate 9 away from the display panel 1, and then an oleophobic material is plated on the light-emitting surface of the cover plate 9, and finally a preliminary quality inspection is performed.

[0058] like Figure 9 and Figure 10As shown, in order to reduce the impact of ambient light on the display panel 1, a polarizer 7 is provided between the cover plate 9 and the display panel 1 to filter the ambient light. To prevent light leakage from the side of the polarizer 7, a light absorption pattern 77 is provided on at least one side of the polarizer 7. The light absorption pattern 77 is provided near the edge of the polarizer 7. The side of the light absorption pattern 77 near the display area 11 is farther away from the display area 11 than the side of the light shielding portion 91 near the display area 11. The light absorption pattern 77 absorbs the outgoing light from the edge of the display area 11, thereby preventing the outgoing light from emitting from the side of the polarizer 7 and causing light leakage from the frame of the display module. In this embodiment, the width of the light absorption pattern 77 can be between 0.05-0.1 mm. In this embodiment, the width of the light absorption pattern 77 can be set to 0.05 mm, 0.06 mm, 0.07 mm, 0.09 mm, or 1 mm. The distance between the side of the light absorption pattern 77 closest to the display area 11 and the side of the light shielding portion 91 closest to the display area 11 is a first distance. The first distance is greater than or equal to 0.1 mm, and can specifically be between 0.1 and 0.2 mm. In this embodiment, the first distance can be set to 0.1 mm, 0.12 mm, 0.14 mm, 0.18 mm, or 0.2 mm.

[0059] like Figure 11 As shown, the polarizer 7 includes a first supporting layer 71, a phase difference layer 72, a second supporting layer 73, and a polarizing functional layer 74. The polarizing functional layer 74 is disposed on the display side of the display panel 1, the second supporting layer 73 is disposed on the side of the polarizing functional layer 74 away from the display panel 1, the phase difference layer 72 is disposed on the side of the second supporting layer 73 away from the display panel 1, and the first supporting layer 71 is disposed on the side of the phase difference layer 72 away from the display panel 1. It can be understood that the supporting layer on the side of the phase difference layer 72 away from the display panel 1 is the first supporting layer 71, and the supporting layer between the polarizing functional layer 74 and the phase difference layer 72 is the second supporting layer 73.

[0060] A light-absorbing pattern 77 can be provided on one side of the polarizer 7, or on both sides of the polarizer 7. The light-absorbing pattern 77 includes multiple light-absorbing portions 771, which can include recessed portions 7711. Light emitted from the display area 11 is reflected multiple times between the multiple recessed portions 7711 on the first supporting layer 71, thereby reducing the intensity of light emitted from the edge of the display area 11 and achieving a certain light-absorbing effect. The recessed portions 7711 can also be filled with a light-absorbing material 7712 to absorb light during reflection, further enhancing the light-absorbing effect of the light-absorbing pattern 77. The light-absorbing material 7712 can be a black material.

[0061] Since the support layer itself has a certain strength and can protect the light absorbing material 7712, the light absorbing patterns 77 are all set on the support layer. Figures 12 to 14As shown, a light absorption pattern 77 may be provided on a side of the first supporting layer 71 away from the display panel 1. Figures 15 to 17 As shown, light absorption patterns 77 may also be provided on both the first supporting layer 71 and the second supporting layer 73 on a side away from the display panel 1. When the light absorption patterns 77 are provided on both the first supporting layer 71 and the second supporting layer 73, the orthographic projection of the light absorption pattern 77 on the first supporting layer 71 on the display panel 1 and the orthographic projection of the light absorption pattern 77 on the second supporting layer 73 on the display panel 1 overlap with each other.

[0062] The polarizer 7 may further include a first cover layer 75 and a second cover layer 76. The second cover layer 76 is disposed between the polarizing layer 74 and the display side of the display panel 1. The first cover layer 75 is disposed on the side of the first support layer 71 away from the display panel 1. The first cover layer 75 is disposed on the side of the first support layer 71 where the light-absorbing pattern 77 is disposed to prevent the light-absorbing material 7712 from escaping and affecting the display panel 1. The first cover layer 75 and the second cover layer 76 may be pressure-sensitive adhesives, which can increase the bonding strength with the first support layer 71 when under pressure. The thickness of the pressure-sensitive adhesive may be 5-15 μm. In this embodiment, the thickness of the pressure-sensitive adhesive may be 5 μm, 8 μm, 11 μm, 13 μm, or 15 μm.

[0063] The cross-sectional shape of the concave portion 7711 is a triangle, a trapezoid or a rhombus. When only the first support layer 71 is provided with the light absorption pattern 77, as shown in FIG. Figure 12 As shown, the edge of the first supporting layer 71 may be provided with three adjacent triangular recessed portions 7711, as shown in FIG. Figure 13 As shown, three adjacent trapezoidal recesses 7711 may be provided at the edge of the first supporting layer 71. Figure 14 As shown, three adjacent diamond-shaped recesses 7711 may be provided at the edge of the first support layer 71. The recesses 7711 may be provided as grooves along the extension direction of the edge profile of the support layer, or as discontinuous recessed units along the extension direction of the edge profile of the support layer.

[0064] When the first supporting layer 71 and the second supporting layer 73 are both provided with the light absorption pattern 77, as shown in FIG. Figure 15 As shown, the shape of the recessed portion 7711 on the first supporting layer 71 and the shape of the recessed portion 7711 on the second supporting layer 73 can be the same, so that light can be evenly reflected and absorbed by the light absorption pattern 77 of the first supporting layer 71 and the light absorption pattern 77 of the second supporting layer 73. For example, when the shape of the recessed portion 7711 on the first supporting layer 71 is triangular, the shape of the recessed portion 7711 on the second supporting layer 73 is also triangular, as shown in FIG. Figure 16 As shown, when the shape of the concave portion 7711 on the first supporting layer 71 is a trapezoid, the shape of the concave portion 7711 on the second supporting layer 73 is also a trapezoid, as shown in FIG. Figure 17As shown, when the shape of the recessed portion 7711 on the first supporting layer 71 is a diamond, the shape of the recessed portion 7711 on the second supporting layer 73 is also a diamond.

[0065] Of course, the shape of the recessed portion 7711 on the first supporting layer 71 and the shape of the recessed portion 7711 on the second supporting layer 73 may also be different. For example, when the shape of the recessed portion 7711 on the first supporting layer 71 is triangular, the shape of the recessed portion 7711 on the second supporting layer 73 may be trapezoidal or rhombus-shaped. Those skilled in the art may select the shape according to actual needs.

[0066] In addition, whether the light absorption pattern is provided only on the side of the first supporting layer 71 away from the display panel, or the light absorption pattern is provided on the sides of the first supporting layer 71 and the second supporting layer 73 away from the display panel, the shape of the recessed portion 7711 on the same supporting layer can also be set to be different. For example, the shape of the recessed portion 7711 on the first supporting layer 71 can include a triangular recessed portion 7711, an irregular recessed portion 7711, or a diamond recessed portion 7711. Those skilled in the art can make a selection according to actual needs.

[0067] like Figure 18 and 19 As shown, the polarizer 7 is provided with a nanoimprinting area 78, and the recessed portion 7711 can be formed in the nanoimprinting area 78 of the support layer by nanoimprinting technology using a nanoimprinting mold 100. Compared with attaching and spraying the light absorption pattern 77 on the support layer, the nanoimprinting technology has higher precision and better effect, and because the recessed portion 7711 is directly formed using the support layer itself, it will not have a significant impact on the stacking thickness of the display module.

[0068] Without the light absorption pattern 77, the polarizer 7 needs to be expanded outward away from the display area 11 to prevent light from the edge of the display area 11 from being emitted from the side of the polarizer 7. With the light absorption pattern 77, it can absorb the light emitted from the display edge, thereby reducing the overlap width between the orthographic projection of the polarizer 7 on the display panel 1 and the orthographic projection of the cover plate 9 on the display panel 1. The overlap width can be reduced by 0.15-0.2 mm compared to the polarizer 7 without the light absorption pattern 77. In this embodiment, the overlap width can be reduced by 0.15 mm, 0.16 mm, 0.18 mm, 0.19 mm, or 0.2 mm compared to the polarizer 7 without the light absorption pattern 77.

[0069] The present disclosure also provides a display device, which may include the display module described above. The specific structure and beneficial effects of the display device can be referenced with respect to the display module, which has been described in detail above and will not be further elaborated here.

[0070] It should be noted that, in addition to the display module, the display device also includes other necessary components and components, such as a housing, a circuit board, a power cord, etc. Those skilled in the art can make corresponding supplements based on the specific usage requirements of the display device, which will not be repeated here.

[0071] The display device can be a traditional electronic device, such as a mobile phone, a computer, a television, and a camcorder, or it can be an emerging wearable device, such as a virtual reality device and an augmented reality device, which are not listed here one by one.

[0072] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein.
