Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a display module and electronic equipment. BACKGROUND

[0002] At present, the display screen frame of a relatively high-end mobile terminal (such as a mobile phone or a tablet computer) is increasingly narrow, which causes the edge region of a polarizing sheet and the touch control region of a display screen to be increasingly close, and the overlapping region of the polarizing sheet and glass ink to be increasingly small. When natural light in the environment successively passes through air, a cover plate and optical glue, it will be refracted at the interface of two adjacent media, so that the edge of the polarizing sheet is seen by the naked eye under a large viewing angle.

[0003] In addition, the polarizing sheet is polished and ground at the side during processing, which causes a certain proportion of cracks, scratches or pits and other defects to exist in the region of about 0.3 mm at the edge of the polarizing sheet. Therefore, the narrow-frame display screen further magnifies the poor appearance of the edge of the polarizing sheet under a large viewing angle. SUMMARY

[0004] To solve the above problems, the purpose of the present application is to provide a display module and electronic equipment, which are used to solve the problems of the leakage of the polarizing sheet of the existing narrow-frame display module under a large viewing angle and the magnification of the poor appearance of the edge of the polarizing sheet.

[0005] In a first aspect, the present application provides a display module, which comprises:

[0006] a substrate, a polarizing sheet, an optical glue layer and an ink layer which are sequentially stacked;

[0007] The ink layer is located in the non-display region of the display module.

[0008] The optical glue layer and the ink layer have an overlapping region.

[0009] The edge of the polarizing sheet is projected onto the optical glue layer within the overlapping region.

[0010] The optical glue layer in the overlapping region has a first surface facing the polarizing sheet and a second surface facing the ink layer.

[0011] At least one of the first surface and the second surface is provided with a pattern for causing the light to be diffusely reflected in the optical glue layer.

[0012] As a further improvement of the present application, the first surface and the second surface are both provided with a pattern.

[0013] As a further improvement of the present application, the pattern is a continuous pattern and / or an intermittent pattern with a fixed interval.

[0014] As a further improvement of the present application, the fixed interval is 0.02mm-0.5mm.

[0015] As a further improvement of the present application, the orthographic projection of the pattern on the polarizer covers the edge of the polarizer.

[0016] As a further improvement of the present application, the length of the pattern in the direction parallel to the optical adhesive layer is 0.3mm-1.0mm.

[0017] As a further improvement of the present application, the processing technology of the pattern includes one or more of pressing, film coating and laser.

[0018] As a further improvement of the present application, an optical shielding layer is further provided between the first surface and the polarizer to shield the edge of the polarizer.

[0019] As a further improvement of the present application, the optical shielding layer extends to above the bending area of the substrate away from one end of the polarizer and is bonded to the substrate through a glue layer.

[0020] As a further improvement of the present application, the optical shielding layer is an anti-reflection material.

[0021] As a further improvement of the present application, the thickness of the optical shielding layer is 5μm-20μm.

[0025] The optical adhesive layer and the ink layer have an overlapping area.

[0026] The orthographic projection of the edge of the polarizer on the optical adhesive layer is located in the overlapping area.

[0027] An optical shielding layer is provided between the optical adhesive layer and the polarizer to shield the edge of the polarizer.

[0028] In a third aspect, the present application provides an electronic device comprising the display module as described above.

[0029] The beneficial effects of the present application are: by performing the patterning treatment at the position where the optical glue is close to the edge of the polarizing sheet, the light is diffused in the optical glue layer, the refraction and specular reflection of the light are reduced, and the edge leakage problem of the polarizing sheet under the large viewing angle condition is avoided; meanwhile, the light shielding layer is additionally arranged at the edge position of the polarizing sheet, which is used to shield the edge of the polarizing sheet, and the undesirable appearance of the edge of the polarizing sheet under the large viewing angle condition is avoided.

[0040] In the related art, as shown in Figure 5 and Figure 6 , the light shielding layer is arranged on the edge of the polarizing sheet, and the light shielding layer is arranged on the edge of the polarizing sheet. Figure 5A structure schematic diagram of a narrow-frame display module, Figure 6 A structure schematic diagram of a non-narrow-frame display module. In order to facilitate understanding, the X-axis direction in the figure is the length direction of the display module, and the Y-axis direction is the thickness direction of the display module.

[0041] As can be seen from Figure 6 , the polarizer (POL) 3 is arranged inside the optical adhesive layer (OCA) 2, that is, the length of the polarizer 3 is greater than the length of the optical adhesive layer 2, so that the edge of the polarizer 3 is outside the length range of the optical adhesive layer 2. The orthogonal projection of the ink layer 9 on the optical adhesive layer 2 and the orthogonal projection of the polarizer 3 on the optical adhesive layer 2 have a sufficient overlapping area, that is, the length L1 of the overlapping area is sufficient. Therefore, the refraction or reflection occurring at the edge of the polarizer 3 in the non-narrow-frame display module will be blocked by the ink layer 9, and even in the case of a large viewing angle, the human eye will not see the edge of the polarizer 3 and the adverse problems near the edge.

[0042] As can be seen from Figure 5 , the polarizer (POL) 30 is arranged outside the optical adhesive layer (OCA) 20, that is, the length of the polarizer 30 is less than the length of the optical adhesive layer 20, so that the edge of the polarizer 30 is within the length range of the optical adhesive layer 20. The overlapping area of the orthogonal projection of the ink layer 90 on the optical adhesive layer 20 and the orthogonal projection of the polarizer 30 on the optical adhesive layer 20 is small, that is, the length L of the overlapping area is not sufficient. For example, the length of the overlapping area of the orthogonal projection of the ink layer 90 on the optical adhesive layer 20 and the orthogonal projection of the polarizer 30 on the optical adhesive layer 20 in some narrow-frame display modules is only 0.2mm-0.4mm, and if the tolerance is considered, the length of the overlapping area will be smaller. Therefore, when in the case of a large viewing angle, the refraction or reflection occurring at the edge of the polarizer 30 in the narrow-frame display module will not be blocked by the ink layer 90, and the human eye will see the edge of the polarizer 3, and will also magnify the adverse problems near the edge.

[0043] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0044] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly.

The terms "include" and / or "contain" are used to specify the presence of the elements, steps, operations and / or components, but do not exclude the presence or addition of one or more other elements, steps, operations and / or components. The terms "first", "second" and the like can be used to describe various elements, which do not represent the order and do not limit the elements. In addition, in the description of the present application, unless otherwise stated, the meaning of "a plurality of" is two and more than two. These terms are only used to distinguish one element from another. These and / or other aspects become apparent from the following drawings and the description of the embodiments described in the present application. The drawings are used to depict the embodiments described in the present application only for illustrative purposes. Those skilled in the art will easily recognize from the following description that alternative embodiments of the structures and methods shown in the present application can be employed without departing from the principles of the present application.

[0046] As shown in Figure 1 , a display module according to an embodiment of the present application, which is a narrow-frame display module, includes a substrate (panel) 40, a polarizer (POL) 30, an optical adhesive layer (OCA) 20, an ink layer (CG Ink) 90 and a cover plate (CG) 10, which are sequentially stacked from bottom to top.

[0047] Specifically, the ink layer 90 is arranged on a partial area of the lower surface of the cover plate 10, which is a non-visible area of the display module. The optical adhesive layer 20 and the ink layer 90 have an overlapping area, i.e., the orthographic projection of the ink layer 90 on the optical adhesive layer 20 partially overlaps the optical adhesive layer 20. The orthographic projection of the edge of the polarizer 30 on the optical adhesive layer 20 is located in the overlapping area. The optical adhesive layer 20 in the overlapping area has a first surface facing the polarizer 30, for example, the lower surface of the overlapping area, and a second surface facing the ink layer 90, for example, the upper surface of the overlapping area.

[0048] At least one of the first surface and the second surface is provided with a pattern for causing diffuse reflection of light in the optical adhesive layer 20.

[0049] In an alternative embodiment, as shown in Figure 2 , the corresponding pattern 201 is arranged only on the lower surface of the overlapping area. When the edge of the polarizer 30 refracts or reflects specularly, the corresponding refracted light or reflected light enters the optical adhesive layer 20 and is diffusely reflected under the action of the pattern 201 arranged on the lower surface. The refracted light and the specularly reflected light at the edge of the polarizer 30 do not exit the cover plate 10 and thus are not observed by the human eye. This solves the problem of "leakage" of the narrow-frame display module and the magnification of the edge defects of the polarizer 30.

[0050] Alternatively, as another embodiment, as shown in FIG. 2B, only the upper surface of the overlapping region is provided with a corresponding pattern 201. When the edge of the polarizer 30 undergoes refraction or mirror reflection, the corresponding refracted light or reflected light enters the optical adhesive layer 20 and is diffusely reflected under the action of the pattern 201 provided on the upper surface. The refracted light and the mirror reflected light at the edge of the polarizer 30 will not be emitted out of the cover plate 10, and thus will not be observed by the human eye. This solves the problem of "leakage" of the narrow-frame display module and the magnification of the edge defects of the polarizer 30. Figure 3

[0051] Alternatively, as another embodiment, as shown in FIG. 2C, both the upper surface and the lower surface of the overlapping region are provided with a corresponding pattern 201. When the edge of the polarizer 30 undergoes refraction or mirror reflection, the corresponding refracted light or reflected light enters the optical adhesive layer 20 and is first diffusely reflected under the action of the pattern 201 provided on the lower surface; then, the diffusely reflected light is again diffusely reflected under the action of the pattern 201 provided on the upper surface, and thus the refracted light or the mirror reflected light at the edge of the polarizer 30 is diffusely reflected between the upper and lower surfaces of the optical adhesive layer 20 under the action of the patterns 201 provided on the upper and lower surfaces. The refracted light and the mirror reflected light at the edge of the polarizer 30 will not be emitted out of the cover plate 10, and thus will not be observed by the human eye. This solves the problem of "leakage" of the narrow-frame display module and the magnification of the edge defects of the polarizer 30. Figure 1

[0052] Preferably, both the upper surface and the lower surface of the overlapping region in the present embodiment are provided with a corresponding pattern. This improves the "blocking" effect of the refracted light and the mirror reflected light at the edge of the polarizer 30. It is not difficult to understand that if a pattern is provided only on one of the upper and lower surfaces of the overlapping region, a small amount of refracted light and mirror reflected light may be emitted out of the cover plate 10. When patterns are provided on both the upper and lower surfaces of the overlapping region, even if a small amount of refracted light and mirror reflected light "escapes" from the lower surface of the overlapping region, it can be "captured" by the upper surface of the overlapping region. Thus, under the cooperation of the patterns on the upper and lower surfaces of the overlapping region, the refracted light at the edge of the polarizer 30 can be more effectively prevented from being emitted out of the cover plate 10, and thus the problem of "leakage" of the narrow-frame display module and the magnification of the edge defects of the polarizer 30 can be better solved. In application, the position of the pattern can be selected according to actual conditions, which is not specifically limited in the present application.

[0053] In an optional embodiment, the pattern is a continuous pattern and / or an intermittent pattern with a fixed interval.

[0054] For example, as shown in FIG. 2D, the pattern is a continuous pattern. Figure 1 ​​As shown, the pattern 201 arranged on the overlapping area can be a continuous pattern such as a continuous wavy pattern, a continuous zigzag pattern or a continuous grid pattern; or can be an intermittent pattern with certain intervals. In application, other shapes of patterns can also be selected as long as the arranged pattern can cause the refracted light at the edge of the polarizer 30 to be diffusely reflected, and the shape of the pattern is not specifically limited in the present application. It should be noted that if an intermittent pattern with fixed intervals is selected, the interval between any two adjacent protrusions or recesses should be arranged within the range of 0.02mm-0.5mm, for example, the interval between any two adjacent protrusions or recesses is 0.05mm, 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm or 0.45mm, etc., so as to avoid the refracted light at the edge of the polarizer 30 directly shooting out from the interval due to too large interval.

[0055] The patterns on the upper and lower surfaces of the overlapping area can be the same pattern or different patterns. Optionally, the patterns on the upper and lower surfaces of the overlapping area can be the same continuous pattern, for example, in the present embodiment, the patterns 201 on the upper and lower surfaces of the overlapping area are both continuous wavy patterns; or the patterns on the upper and lower surfaces of the overlapping area can be continuous patterns with different shapes; or the patterns on the upper and lower surfaces of the overlapping area can be the same intermittent pattern; or the patterns on the upper and lower surfaces of the overlapping area can be different intermittent patterns; or the patterns on the upper and lower surfaces of the overlapping area can be a continuous pattern and an intermittent pattern respectively. The arrangement of the patterns on the upper and lower surfaces of the overlapping area can be selected according to the specific arrangement of the display module and the processing technology, and the present application does not specifically limit it.

[0056] In an optional embodiment, as shown in Figure 1 The orthographic projection of the pattern 201 on the polarizer 30 covers the edge of the polarizer 30. In this way, it can be ensured that the refracted light or the specular reflected light at the edge of the polarizer 30 will pass through the pattern 201, thereby ensuring that the refracted light will be diffusely reflected in the optical adhesive layer 20 under the action of the pattern 201, so as to ensure the "edge leakage" prevention effect of the pattern 201.

[0057] Furthermore, the length of pattern 201 in the direction parallel to the optical adhesive layer 20 is 0.3mm-1.0mm. That is, the length of pattern 201 on the upper and lower surfaces of the overlapping area is 0.3mm-1.0mm. For example, the length of pattern 201 on the upper and lower surfaces of the overlapping area is 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, or 0.9mm, etc. According to the overlap length of polarizer 30 and ink layer 90 in this embodiment, the length of pattern 201 conforms to the above range, which can ensure that the refracted light at the edge of polarizer 30 will pass through pattern 201, and thus undergo diffuse reflection under the action of pattern 201. In application, the length of pattern 201 on the upper and lower surfaces of the overlapping area can be adjusted according to the overlap length of polarizer 30 and ink layer 90. This length is based on ensuring that the refracted light at the edge of polarizer 30 will pass through pattern 201. This application does not specifically limit the length of pattern 201.

[0058] In one optional embodiment, the processing technology of pattern 201 includes one or more of pressing, lamination, and laser processing. For example, a groove of the desired shape can be pressed into the upper and lower surfaces of the overlapping area by pressing to cause diffuse reflection of the refracted light at the edge of the polarizer 30; a frosted film of a specific shape can be applied to the upper and lower surfaces of the overlapping area to cause diffuse reflection of the refracted light at the edge of the polarizer 30 under the action of the frosted film; or a pattern of the desired shape can be processed into the upper and lower surfaces of the overlapping area by laser processing to cause diffuse reflection of the refracted light at the edge of the polarizer 30.

[0059] In one alternative implementation, such as Figure 1 As shown, a light-shielding layer 801 is also provided between the lower surface of the overlapping area and the polarizer 30 to shield the edge of the polarizer 30. For example, the light-shielding layer 801 is black light-shielding tape, which is adhered to the upper surface of the polarizer 30 and covers the edge of the polarizer 30, thereby blocking the edge of the polarizer 30 to prevent light from being refracted or specularly reflected at the edge of the polarizer 30, so as to further ensure that the human eye cannot observe the edge of the polarizer 30 or any defects at the edge of the polarizer 30.

[0060] It can be understood that the pattern 201 arranged on the upper and lower surfaces of the overlapping area cannot completely "block" the refracted light at the edge of the polarizing sheet 30, that is, there will always be a small amount of refracted light emitted from the cover plate 10. Further, the small amount of refracted light emitted from the cover plate 10 can be compensated by using the light shielding layer 801. At the same time, since the light shielding layer 801 also has an edge, the refracted light at the edge of the light shielding layer 801 will also have a similar "leakage" problem as the edge of the polarizing sheet 30. The pattern 201 arranged on the upper and lower surfaces of the overlapping area can also make the refracted light at the edge of the light shielding layer 801 be diffusely reflected in the optical adhesive layer 20 under the action of the pattern 201, avoiding the "leakage" problem of the edge of the light shielding layer 801. Thus, under the cooperation of the pattern 201 and the light shielding layer 801, the "leakage" problem of the narrow frame display module can be solved.

[0061] Preferably, the light shielding layer 801 is an anti-reflection material. For example, the light shielding layer 801 is rubber or resin with porous surface or surface sanding treatment, etc. to avoid the refracted light at the edge of the polarizing sheet 30 from emitting refraction or specular reflection when passing through the light shielding layer 801.

[0062] More preferably, the thickness of the light shielding layer 801 is 5-20 μm. For example, the thickness of the light shielding layer 801 is 8 μm, 10 μm, 12 μm, 14 μm, 15 μm, 16 μm, 18 μm or 19 μm, etc. The light shielding layer 801 meeting the above thickness range can solve the "leakage" problem of the narrow frame display module without excessively increasing the thickness of the display module.

[0063] In an alternative embodiment, the light shielding layer 801 extends to above the bending area of the substrate 40 away from one end of the polarizing sheet 30 and is bonded to the substrate 40 through the glue layer 80.

[0064] It can be understood that in order to reduce the frame of the display module, the end of the substrate 40 away from the polarizing sheet 30 is bent downward to form a bending area, and the Bonding area is arranged in the bending area. The end of the light shielding layer 801 away from the polarizing sheet 30 is extended in the length direction, for example, the right end of the light shielding layer 801 is extended to the right, so that the length of the light shielding layer 801 is equal to the length of the glue layer 80, so that the light shielding layer 801 covers the bending area of the substrate 40. In this way, the light shielding layer 801 can not only solve the "leakage" problem of the narrow frame display module, but also protect the bending area of the substrate 40 to avoid damage to the bending area due to bending stress.

[0065] As Figure 4As shown, the display module according to another embodiment of the present application is a narrow-frame display module, which comprises, from bottom to top, a substrate 40, a polarizer 30, an optical adhesive layer 20, an ink layer 90, and a cover plate 10.

[0066] Specifically, the ink layer 90 is arranged on a partial area of the lower surface of the cover plate 10, which is a non-visible area of the display module. The optical adhesive layer 20 and the ink layer 90 overlap each other, i.e., the ink layer 90 partially overlaps the optical adhesive layer 20. The edge of the polarizer 30 is projected onto the optical adhesive layer 20 and located in the overlapping area. An optical shielding layer 801 is arranged between the optical adhesive layer 20 and the polarizer 30 to shield the edge of the polarizer 30.

[0067] For example, the optical shielding layer 801 is a black optical shielding tape, which is attached to the upper surface of the polarizer 30 and covers the edge of the polarizer 30, so as to shield the edge of the polarizer 30 and prevent the incident light from being refracted or specularly reflected at the edge of the polarizer 30, thereby ensuring that the edge of the polarizer 30 and the defects at the edge of the polarizer 30 cannot be observed by the human eye.

[0068] Preferably, the optical shielding layer 801 is an anti-reflection material. For example, the optical shielding layer 801 is rubber or resin with porous surface or frosted surface, so as to avoid the refracted light at the edge of the polarizer 30 from being refracted or specularly reflected when passing through the optical shielding layer 801.

[0069] More preferably, the thickness of the optical shielding layer 801 is 5 μm-20 μm. For example, the thickness of the optical shielding layer 801 is 8 μm, 10 μm, 12 μm, 14 μm, 15 μm, 16 μm, 18 μm, or 19 μm, etc. The optical shielding layer 801 with the above thickness range can solve the problem of "leakage of the edge" of the narrow-frame display module without excessively increasing the thickness of the display module.

[0070] In the description provided herein, a large number of specific details are illustrated. However, it can be understood that the embodiments of the present application can be practiced without these specific details.
