Since most folding display modules use organic film materials to meet the bending characteristics, and the overall supporting performance of organic film materials is poor. After assembly, there are obvious marks at the ink overprint position, which affects the display effect.

[0046] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0047] like Figures 1 to 8 As shown, according to the first aspect of the present application, a display module 1 is provided, including a cover body 10, a shading layer 20 and a display panel 30, wherein the shading layer 20 is arranged on one side surface of the cover body 10; the display panel 30 is arranged on the side of the shading layer 20 away from the cover body 10, and the display panel 30 includes a display area AA and a non-display area NA arranged on the periphery of the display area AA; wherein the shading layer 20 is arranged corresponding to the non-display area NA, the display module 1 is provided with at least one light-transmitting area 21, the light-shielding layer 20 is provided with a plurality of first holes 22 in the light-transmitting area 21, the first holes 22 penetrate the light-shielding layer 20 along the thickness direction of the light-shielding layer 20, and the light transmittance of the light-transmitting area 21 ranges from 5% to 20%.
[0048] The cover body 10 may be a rigid cover body or a flexible cover body. The material of the rigid cover body may be glass or the like. The material of the flexible cover body may be one of colorless polyimide (PI), polycarbonate (PC), polynorbornene (PNB), polyethylene terephthalate (PET), etc. When the display panel 30 is a flexible panel, the cover body 10 may be a flexible cover body, so that the display panel 30 is easy to fold. The cover body 10 may protect the display panel 30 and prevent the display panel 30 from being damaged by mechanical impact.
[0049] The display panel 30 may be an OLED panel, a Mini-LED panel, a Micro-LED panel, or the like.
[0050] like Figure 1 As shown in FIG. 3 , the display panel 30 includes a display area AA and a non-display area NA disposed outside the display area AA. The display area AA can be used to display images. The display area AA has multiple sub-pixels, such as red sub-pixels, green sub-pixels, and blue sub-pixels. Sub-pixels of different colors can emit light of different colors, thereby realizing color display. The non-display area NA can be provided with a driving circuit, such as a gate driving circuit. The driving circuit is used to drive the sub-pixel display.
[0051] like Figures 1 to 5 As shown, the light emitting surface of the display panel 30 faces the side of the light shielding layer 20. The light shielding layer 20 can be set corresponding to the non-display area NA, and the light shielding layer 20 can shield the metal wiring and the like in the non-display area NA to prevent the metal wiring and the like from reflecting light and affecting the appearance of the display module 1. The light shielding layer 20 does not cover the display area AA, so as to prevent the light shielding layer 20 from shielding the display screen of the display area AA.
[0052] like Figure 1 As shown, Figure 1 The positions of the light-transmitting area 21 and the first hole 22 in the display module 1 are shown. It should be noted that, from the top view of the display module 1, the first hole 22 will be blocked by the cover body 10. The light-transmitting area 21 is set corresponding to the non-display area NA of the display panel 30. The light-transmitting area 21 can be set corresponding to a sensor or the like. The sensor can be set on the side of the display panel 30 away from the cover body 10, and the sensor can receive the light transmitted by the light-transmitting area 21, thereby realizing the sensing function.
[0053] The light transmittance of the light-transmitting area 21 can be set according to the photosensitivity requirements of the sensor. The light transmittance of the light-transmitting area 21 refers to the overall light transmittance of the display module 1 in the light-transmitting area 21, that is, the ratio of the brightness of the light incident on the sensor to the brightness of the light on the side of the cover body 10 away from the sensor. The light transmittance of the light-transmitting area 21 can be 5% to 20%. For example, the light transmittance of the light-transmitting area 21 can be 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, etc.
[0054] The light shielding layer 20 is a material with a light shielding effect. For example, the light shielding layer 20 can be black ink, etc., but is not limited thereto. The light transmittance of the light shielding layer 20 in the light-transmitting area 21 is greater than the light transmittance of other areas. For example, the light transmittance of the light shielding layer 20 in the light-transmitting area 21 ranges from 5% to 25%. The light transmittance of other areas of the light shielding layer 20 except the light-transmitting area 21 can be less than 5%. The smaller the light transmittance of other areas of the light shielding layer 20, the better the light shielding effect. Optionally, the light transmittance of other areas of the light shielding layer 20 can be less than 2%. The light shielding layer 20 can be formed on one side surface of the cover body 10 by a printing process, but is not limited thereto.
[0055] Optionally, the thickness of the light shielding layer 20 is 2 micrometers to 6 micrometers. For example, the thickness of the light shielding layer 20 is 2 micrometers, 2.5 micrometers, 3 micrometers, 3.5 micrometers, 4 micrometers, 4.5 micrometers, 5 micrometers, 5.5 micrometers, 6 micrometers, etc.
[0056] It should be noted that there is no boundary between the light-transmitting area 21 and other areas of the light-shielding layer 20. The material of the light-transmitting area 21 of the light-shielding layer 20 is the same as that of the non-light-transmitting area 21, and there is no thickness difference between the two areas, so no obvious imprint will be produced.
[0057] In the light-shielding layer 20, the light transmittance of the light-transmitting area 21 is greater than the light transmittance of the non-light-transmitting area 21. The improvement of the light transmittance of the light-transmitting area 21 is achieved by setting a plurality of first holes 22 in the light-transmitting area 21. The first holes 22 penetrate the light-shielding layer 20 along the thickness direction of the light-shielding layer 20. Since there is no light-shielding material in the first holes 22, its light transmittance is greater than the area where the light-shielding material is set. By setting a plurality of first holes 22, the overall light transmittance of the light transmittance can meet the use requirements. The ratio of the total area of the plurality of first holes 22 corresponding to a light-transmitting area 21 to the area of the light-transmitting area 21 can be 0.05 to 0.2. When the ratio of the total area of the first holes 22 to the area of the light-transmitting area 21 increases, the light transmittance of the light-transmitting area 21 increases.
[0058] The area of the light-transmitting area 21 can be set according to the area of the corresponding photosensitive surface of the sensor. The area of the light-transmitting area 21 can be greater than or equal to the area of the photosensitive surface of the sensor. The light-transmitting area 21 is set corresponding to the non-display area NA of the display panel 30, which means that the light-transmitting area 21 does not exceed the range of the non-display area NA.
[0059] In some embodiments, Figure 1 As shown, the display module 1 is provided with a light-transmitting area 21 .
[0060] In some embodiments, the display module 1 is provided with a plurality of light-transmitting areas 21. The transmittance of each light-transmitting area 21 can be adjusted according to the photosensitivity of the corresponding sensor, that is, the plurality of light-transmitting areas 21 can have different transmittances from each other. In the related art, light-transmitting areas 21 with different transmittances use different light-transmitting inks, and there is color difference in appearance of different light-transmitting inks, which will lead to inconsistent appearance of the display module 1. In the present application, the material of the light-shielding layer 20 of the light-transmitting area 21 is the same as the material of the light-shielding layer 20 outside the light-transmitting area 21, and the transmittance of different light-transmitting areas 21 is adjusted by adjusting the opening area of the first hole 22, thereby avoiding color difference in the appearance of the display module 1.
[0061] Alternatively, if Figures 2 to 5 As shown, the display module 1 also includes a first functional layer 40 which is contacted and arranged on the side of the display panel 30 away from the cover body 10; wherein the first functional layer 40 is provided with a second hole 41 corresponding to the light-transmitting area 21, each first hole 22 is located in the second hole 41, and the depth of the second hole 41 is less than or equal to the thickness of the first functional layer 40.
[0062] like Figures 2 to 5 As shown, the first functional layer 40 is arranged on the side of the display panel 30 away from the light emitting surface of the display panel 30. The first functional layer 40 is arranged in contact with the display panel 30. The first functional layer 40 can be a single film layer or a stack of multiple film layers. The first functional layer 40 can be a stack of one or more of flexible materials and rigid materials. The flexible material can be polyethylene terephthalate, polyimide, polycarbonate, carbon fiber, etc. The rigid material can be stainless steel, titanium, aluminum, copper, etc. The first functional layer 40 is used to support and protect the display panel 30 so that the back of the display panel 30 is not easily damaged by impact. The side of the first functional layer 40 close to the display panel 30 may include an adhesive layer (not shown in the figure), and the adhesive layer is used to bond the first functional layer 40 to the surface of the display panel 30. When the first functional layer 40 is a stack of multiple film layers, an adhesive layer (not shown in the figure) can also be provided between two adjacent film layers.
[0063] A second hole 41 may be provided on the side of the first functional layer 40 away from the light-emitting surface of the display panel 30, and the second hole 41 is provided corresponding to the light-transmitting area 21, and the first holes 22 are all located in the second hole 41. The second hole 41 may be one hole or multiple holes corresponding to the light-transmitting area 21, and the present application does not limit this. By providing the second hole 41 on the first functional layer 40, the transmittance of the first functional layer 40 in the light-transmitting area 21 can be increased, and the transmittance of the light-transmitting area 21 of the display module 1 can be improved.
[0064] like Figures 2 to 5 As shown, the second hole 41 is taken as an example for explanation. The depth of the second hole 41 can be less than or equal to the thickness of the second functional layer 50. That is to say, Figure 2 As shown, when the depth of the second hole 41 is less than the thickness of the second functional layer 50, the second hole 41 does not completely penetrate the first functional layer 40; Figures 3 to 5 As shown, when the depth of the second hole 41 is equal to the thickness of the second functional layer 50 , the second hole 41 completely penetrates the first functional layer 40 .
[0065] Alternatively, if Figures 3 to 5 As shown, the first functional layer 40 includes a stacked backplane layer 411 and a support layer 412, the support layer 412 is arranged on the side of the backplane layer 411 away from the cover plate body 10, and the modulus of the support layer 412 is greater than the modulus of the backplane layer 411; wherein, the depth of the second hole 41 is equal to the thickness of the first functional layer 40, and the opening area of the second hole 41 on the backplane layer 411 is smaller than the opening area of the second hole 41 on the support layer 412.
[0066] The material of the backplane layer 411 may include one or more of silicon dioxide, polyester resin, polyethylene, polypropylene, polystyrene, polylactic acid, polyethylene terephthalate, polyimide or polyurethane, but is not limited thereto. The backplane layer 411 can prevent the display panel 30 from being damaged by external forces and can block water and oxygen.
[0067] The modulus of the support layer 412 is greater than the modulus of the backplane layer 411. The support layer 412 has a certain rigidity and can provide back support and protection for the display panel 30, so that the back of the display panel 30 is not easily damaged by impact. The material of the support layer 412 can be metal, such as stainless steel, copper, aluminum, etc.
[0068] like Figures 3 to 5 As shown, the depth of the second hole 41 is equal to the thickness of the first functional layer 40 , that is, the second hole 41 penetrates the support layer 412 and the back plate layer 411 along the thickness direction of the first functional layer 40 .
[0069] Alternatively, if Figures 3 to 5As shown, the opening area of the second hole 41 on the supporting layer 412 can be larger than the opening area of the second hole 41 on the back plate layer 411, that is, the second hole 41 is a stepped hole. Therefore, the back plate layer 411 can cover the side wall of the second hole 41 on the supporting layer 412, so that the back plate layer 411 provides support for the supporting layer 412, and prevents the side wall of the second hole 41 on the supporting layer 412 from squeezing the display panel 30 and causing marks.
[0070] It should be understood that the depth of the second hole 41 can be set according to the transmittance of the light-transmitting area 21. In order to increase the transmittance of the light-transmitting area 21, the depth of the second hole 41 can be increased, that is, the second hole 41 penetrates more material of the first functional layer 40.
[0071] Alternatively, if Figure 4 and Figure 5 As shown, the display panel 30 is provided with a third hole 31 communicating with the second hole 41 , and the side wall of the second hole 41 on the back plate layer 411 is flush with the side wall of the third hole 31 .
[0072] In order to further improve the light transmittance of the light-transmitting area 21, a third hole 31 may be provided on the display panel 30, and the third hole 31 completely penetrates the display panel 30 along the thickness direction of the display panel 30. Since the third hole 31 is located in the non-display area NA of the display panel 30, the provision of the third hole 31 will not affect the display image of the display panel 30.
[0073] In the present application, two holes are connected, which means that the two holes are not separated by other membrane layers. For example, the second hole 41 is connected with the third hole 31, which means that the second hole 41 is not separated by other membrane layers.
[0074] In the present application, any hole can be realized by laser cutting process. In order to simplify the process, the side wall of the second hole 41 can be flush with the side wall of the third hole 31, so that the first functional layer 40 and the display panel 30 can be opened in the same laser cutting process.
[0075] Optionally, the backplane layer 411 and the display panel 30 may be bonded together before the holes are drilled, so that the backplane layer 411 and the display panel 30 are drilled using the same process. The support layer 412 may be drilled using another process, so that the second holes 41 have different opening areas on the support layer 412 and the backplane layer 411.
[0076] Alternatively, if Figure 4 As shown, there are a plurality of third holes 31 , and each first hole 22 is located in a third hole 31 . The opening area of the third hole 31 is larger than the opening area of the first hole 22 .
[0077] There can be a plurality of third holes 31, and two adjacent third holes 31 are arranged at intervals. One third hole 31 is arranged corresponding to one first hole 22, and light can pass through the corresponding first hole 22 and third hole 31.
[0078] Alternatively, if Figure 4 As shown, the opening area of the third hole 31 is larger than the opening area of the first hole 22. For example, when the shape of the third hole 31 is the same as that of the first hole 22, in the same direction, the opening size of the third hole 31 is 0.1 mm to 0.5 mm larger than the opening size of the first hole 22. For example, the opening size of the third hole 31 is 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, etc. larger than the opening size of the first hole 22.
[0079] The light shielding layer 20 is usually formed on the cover plate body 10, and then the cover plate body 10 with the light shielding layer 20 is bonded to the display panel 30. There is a positioning tolerance during the bonding process. In order to avoid the misalignment of the third hole 31 and the first hole 22 due to the bonding offset, which affects the light transmittance of the light-transmitting area 21, the opening size of the third hole 31 can be larger than the opening size of the first hole 22. In this way, even if there is a bonding offset, the first hole 22 can still be located in the third hole 31, reducing the influence of the process tolerance on the light transmittance of the light-transmitting area 21.
[0080] In some embodiments, the light transmittance of the light-transmitting area 21 of the display module 1 can be further improved by increasing the opening area of the third hole 31 .
[0081] Alternatively, if Figure 4 and Figure 5 The display module 1 includes a second functional layer 50 which is arranged in contact with the display panel 30 and close to the cover body 10; wherein the second functional layer 50 is provided with a fourth hole 51 which is connected to the third hole 31, and the depth of the fourth hole 51 is less than or equal to the thickness of the second functional layer 50.
[0082] The second functional layer 50 is arranged on one side of the light emitting surface of the display panel 30. The surface of the second functional layer 50 on one side close to the display panel 30 is arranged in contact with the display panel 30, and the surface of the second functional layer 50 on one side close to the light shielding layer 20 is arranged in contact with the light shielding layer 20. The second functional layer 50 can be a single-layer film layer or a stack of multiple film layers. The second functional layer 50 can protect the front of the display panel 30 to prevent the display panel 30 from being damaged by impact. The second functional layer 50 can also be used to reduce the reflection of ambient light, etc. The second functional layer 50 can include a stack of one or more layers of organic materials. The organic material can be polyethylene terephthalate, polyimide or polyurethane, etc. The side of the second functional layer 50 close to the display panel 30 can include a glue layer (not shown in the figure), which is used to bond the second functional layer 50 to the surface of the display panel 30. When the second functional layer 50 is a stack of multiple film layers, a glue layer (not shown in the figure) can also be provided between two adjacent film layers.
[0083] Alternatively, if Figure 4 As shown, the depth of the fourth hole 51 is less than the thickness of the second functional layer 50; wherein, there are multiple fourth holes 51, and the sidewalls of the fourth holes 51 are flush with the sidewalls of the third holes 31. By providing the fourth holes 51 on the second functional layer 50, the light transmittance of the second functional layer 50 in the light-transmitting area 21 can be increased, thereby improving the light transmittance of the light-transmitting area 21 of the display module 1.
[0084] When the depth of the fourth hole 51 is less than the thickness of the second functional layer 50, the fourth hole 51 does not completely penetrate the second functional layer 50. The fourth hole 51 can be connected to the third hole 31, and the side wall of the fourth hole 51 is flush with the side wall of the third hole 31. Through the above arrangement, the second functional layer 50 and the display panel 30 can be opened in the same laser cutting process.
[0085] Optionally, the number of the fourth holes 51 is the same as the number of the third holes 31. When the third hole 31 is one hole, the fourth hole 51 is also one hole; when the third hole 31 is a plurality of holes, the fourth hole 51 is also a plurality of holes having the same number as the third hole 31.
[0086] In some embodiments, when the fourth hole 51 is a plurality of holes, the opening area of the fourth hole 51 can be increased to further improve the light transmittance of the light-transmitting area 21 of the display module 1 .
[0087] Alternatively, if Figure 5 As shown, the depth of the fourth hole 51 is equal to the thickness of the second functional layer 50, and the second functional layer 50 includes a stacked adhesive layer 511 and a polarizer 512, and the polarizer 512 is located on the side of the adhesive layer 511 away from the cover body 10; wherein, the opening area of the fourth hole 51 on the polarizer 512 is smaller than the opening area of the fourth hole 51 on the adhesive layer 511.
[0088] The material of the adhesive layer 511 may be a transparent adhesive layer, such as optically clear adhesive (OCA), but is not limited thereto.
[0089] The polarizer 512 can reduce the reflection of ambient light by the display panel 30, and improve the glare problem caused by the reflection of ambient light by the display panel 30. The surface of the polarizer 512 on one side close to the display panel 30 can be bonded to the display panel 30 through an adhesive layer.
[0090] Alternatively, if Figure 5 As shown, the opening area of the fourth hole 51 on the polarizer 512 is smaller than the opening area of the fourth hole 51 on the adhesive layer 511, thereby preventing the adhesive layer 511 from exceeding the side wall of the polarizer 512 along the display plane. During the assembly and bonding process, if the adhesive layer 511 exceeds the side wall of the polarizer 512 along the display plane, the exposed adhesive layer 511 is prone to sticking to foreign matter, and the foreign matter will affect the light transmittance of the light-transmitting area 21. Therefore, by making the opening area of the fourth hole 51 on the polarizer 512 smaller than the opening area of the fourth hole 51 on the adhesive layer 511, the risk of sticking to foreign matter on the adhesive layer 511 can be reduced.
[0091] Alternatively, if Figures 6 to 8 As shown, the shape of the first hole 22 includes a triangle, a quadrilateral, and a circle. The arrangement of the first holes 22 can be set as needed, and the present application does not limit this. The multiple first holes 22 can be symmetrically arranged about the center line of the light-transmitting area 21, so that the light transmittance of the light-transmitting area 21 is uniform.
[0092] like Figure 6 As shown, the shape of the first hole 22 is circular. The plurality of first holes 22 may be distributed in a circular pattern along the center of the light-transmitting area 21, but is not limited thereto.
[0093] like Figure 7 As shown, the shape of the first hole 22 is a triangle. The plurality of first holes 22 may be symmetrically distributed about the center line of the light-transmitting area 21, but is not limited thereto.
[0094] like Figure 8 As shown, the shape of the first hole 22 is a quadrilateral. The plurality of first holes 22 may be distributed in a straight line, but is not limited thereto.
[0095] In the embodiment of the present application, in order to increase the light passing through the light-transmitting area 21, holes can be opened in each film layer of the first functional layer 40 and the second functional layer 50, and the number and size of the holes can be set according to the light transmittance of each film layer in the first functional layer 40 and the second functional layer 50 and the photosensitivity requirements of the sensor. The larger the ratio of the area of the holes to the area of the light-transmitting area 21, the greater the light transmittance of the light-transmitting area 21 of the display module 1.
[0096] Optionally, in the light-transmitting area 21 of the display module 1, the transmittance of the light-shielding layer 20 in the light-transmitting area 21 is 5% to 25%, and the transmittance of other film layers except the light-shielding layer 20 is 50% to 90%, so that the overall transmittance of the light-transmitting area 21 of the display module 1 meets the requirement of 5% to 20%.
[0097] According to the second aspect of the present application, Fig. 9 As shown, a display terminal 2 is provided, comprising the above-mentioned display module 1.
[0098] In this embodiment, if Fig. 9 As shown, the display terminal 2 includes a display module 1 and a terminal body 3, and the display module 1 and the terminal body 3 are combined into one body.
[0099] The light transmittance of the light-transmitting area 21 of the display module 1 ranges from 5% to 20%, thereby meeting the photosensitivity requirements of the sensor.
[0100] In this embodiment, the display terminal 2 can be any product or component with a display function, such as a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, a navigator, etc.
