[0042] Figure 7 is a schematic diagram of a film layer structure of a display module provided by an embodiment of the present application. DETAILED DESCRIPTION
[0043] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.
[0044] Please refer to Figure 1 , Figure 1 is a schematic diagram of a film layer structure of a display module. The display module 00 includes a display panel 01, a polaroid 02, a protective cover plate 03, an optical adhesive layer 04 and a protective adhesive 05.
[0045] The display panel 01 in the display module 00 includes a first panel part 11 and a second panel part 21 arranged oppositely, and a panel bending part 31 for connecting the first panel part 11 and the second panel part 21. That is, the panel bending part 31 can be located between the first panel part 11 and the second panel part 21, and one side of the panel bending part 31 can be connected with the first panel part 11, and the other side of the panel bending part 31 can be connected with the second panel part 21.
[0046] The polarizer 02 in the display module 000 is located on the display side of the display panel 01, and is used to reduce the reflectivity of the display panel 01 to ambient light, so as to ensure that the display effect of the display area in the display panel 01 is better.
[0047] The protective cover plate 03 is located on the side of the polarizer 02 away from the display panel 01. The optical adhesive layer 04 is located between the polarizer 02 and the protective cover plate 03, and the polarizer 02 and the protective cover plate 03 are bonded respectively, so as to realize the bonding between the protective cover plate 03 and the polarizer 02, so that the protective cover plate 03 can protect the display side of the display panel 01.
[0048] The protective adhesive 05 is located on the panel bending part 130, and the protective adhesive 05 is also located on the first panel part 11 and the edge part close to the panel bending part 31. In this way, when the side of the display device assembled with the display module 000 is impacted, the protective adhesive 500 can protect the side of the panel bending part 130 away from the first panel part 110.
[0049] In the process of coating the protective adhesive 05 on the first panel part 11, the protective adhesive 05 will exceed the surface of the polarizer 02 due to the siphon effect. In the case that the thickness of the optical adhesive layer 04 is small, the optical adhesive layer 04 cannot fill the gap, resulting in the generation of bubbles in the area where the protective adhesive 05 exceeds the surface of the polarizer 02, so that the display effect of the display module is poor.
[0050] Please refer to Figure 2 , Figure 2 is a film layer structure schematic diagram of a display module provided by the embodiment of the present application. The display module 000 includes a display panel 100, a polarizer 200, a protective cover plate 300, a light shielding part 400, and a protective adhesive 500.
[0051] The display panel 100 in the display module 000 includes a first panel part 110 and a second panel part 120 arranged oppositely, and a panel bending part 130 used to connect the first panel part 110 and the second panel part 120. That is, the panel bending part 130 can be located between the first panel part 110 and the second panel part 120, one side of the panel bending part 130 can be connected with the first panel part 110, and the other side of the panel bending part 130 can be connected with the second panel part 120.
[0052] The polarizer 200 in the display module 000 is located on the display side of the display panel 100. Here, the display side of the display panel is the side of the first panel portion 110 facing away from the second panel portion 120, and is the side of the display panel 100 used for displaying a picture. The polarizer 200 can be bonded to the display side of the display panel 100, and the polarizer 200 can reduce the reflectivity of the display panel 100 to ambient light, so as to ensure that the picture displayed by the display area in the display panel 100 is better.
[0053] The protective cover plate 300 in the display module 000 is located on the side of the polarizer 200 facing away from the display panel 100. The side of the polarizer 200 facing away from the display panel 100 can be bonded to the protective cover plate 300, so that the protective cover plate 300 can protect the display side of the display panel 100.
[0054] The light shielding portion 400 in the display module 000 is located on the side of the protective cover plate 300 facing the polarizer 200.
[0055] The protective gel 500 in the display module 000 is located on the panel bending portion 130, and is also located on the first panel portion 110 and the edge portion close to the panel bending portion 130. In this way, when the side of the display device equipped with the display module 000 is impacted, the protective gel 500 can protect the side of the panel bending portion 130 facing away from the first panel portion 110. It should be noted that the protective gel 500 can also be located on the side of the second panel portion 120 facing away from the first panel portion 110.
[0056] In the present application, the display module 000 can further include an optical adhesive layer 600. At least part of the optical adhesive layer 600 is located between the polarizer 200 and the protective cover plate 300, and the polarizer 200 and the protective cover plate 300 are bonded respectively, for realizing the bonding between the protective cover plate 300 and the polarizer 200. The optical adhesive layer 600 is usually made of transparent glue (for example, acrylic glue). In this way, it can be ensured that the light emitted by the display panel 100 is emitted after passing through the optical adhesive layer 600 and the protective cover plate 300. In addition, the optical adhesive layer 600 also has good buffering performance, so that after the front of the display module 000 is impacted, the buffering of the optical adhesive layer 600 can reduce the probability of the protective cover plate 300 being broken.
[0057] The portion of the protective colloid 500 on the first panel portion 110 has a first gap K1 with the polarizer 200, that is, the polarizer 200 and the protective colloid 500 can not be in contact by inwardly retracting the side of the polarizer 200 close to the panel bending portion 130, so that the protective colloid 500 can not exceed the surface of the polarizer 200 due to the siphon effect in the process of coating the protective colloid 500 on the first panel portion 110. In this case, even if the thickness of the optical adhesive layer 600 is small, since the polarizer 200 and the protective colloid 500 can not be in contact and the protective colloid 500 can not exceed the surface of the polarizer 200, no bubbles can be generated after the optical adhesive layer 600 and the polarizer 200 are attached, so that the display effect of the display module 000 is better.
[0058] In addition, since the portion of the protective colloid 500 on the first panel portion 110 has the first gap K1 with the polarizer 200, in order to avoid the metal traces in the display panel 100 from leaking through the first gap K1, the orthogonal projection of the light-shielding portion 400 on the protective cover plate 300 intersects with the orthogonal projection of the first gap D1 on the protective cover plate 300, so that the light-shielding portion 400 can effectively shield the metal traces in the display panel 100, achieving an aesthetic purpose.
[0059] In summary, the display module provided by the embodiments of the present application has the first gap between the portion of the protective colloid on the first panel portion and the polarizer, the polarizer and the protective colloid can not be in contact, so that the protective colloid can not exceed the surface of the polarizer due to the siphon effect in the process of coating the protective colloid on the first panel portion. In this case, even if the thickness of the optical adhesive layer is small, since the polarizer and the protective colloid can not be in contact and the protective colloid can not exceed the surface of the polarizer, no bubbles can be generated after the optical adhesive layer and the polarizer are attached, so that the display effect of the display module is better. In addition, in order to avoid the metal traces in the display panel from leaking through the first gap, the orthogonal projection of the light-shielding portion on the protective cover plate intersects with the orthogonal projection of the first gap on the protective cover plate, so that the light-shielding portion can effectively shield the metal traces in the display panel, achieving an aesthetic purpose.
[0060] In the embodiments of the present application, please refer to Figure 3 , Figure 3 is another schematic diagram of a film layer structure of a display module provided by the embodiments of the present application. The display module 000 can further include a plurality of functional film layers 700 on the side of the first panel portion 110 facing the second panel portion 120. The plurality of functional film layers 700 can include a first support layer, a grid adhesive layer, a foam layer, a polyimide film layer, and a copper foil which are stacked in a direction away from the first panel portion.
[0061] The first support layer in the display module 000 can be bonded to one side of the first panel portion 110 facing the second panel portion 120. The first support layer in the display module 000 can be used to support the first panel portion 110. The grid adhesive layer can be located on the side of the first support layer away from the first panel portion, and one side of the grid adhesive layer can be bonded to the side of the first support layer away from the first panel portion. Here, the side of the grid adhesive layer away from the first support layer can be bonded to the side of the foam layer facing the first panel portion. The side of the foam layer away from the first panel portion 110 can be bonded to the polyimide film layer. The side of the polyimide film layer away from the first panel portion 110 can be bonded to the copper foil.
[0062] It should be noted that the display module 000 can further include: a support column 800 located between the plurality of functional film layers 700 and the second panel portion 120, and a second support layer 900. The second support layer 900 is closer to the second panel portion 120 than the support column 800. The second support layer 900 can be used to support the second panel portion 120; and the support column 800 can be used to bond and support the plurality of functional film layers 700 and the second support layer 900.
[0063] In the embodiments of the present application, as shown in Figure 3 The display module 000 can further include an opaque ink layer 1000. The opaque ink layer 1000 is located on the side of the protective cover plate 300 facing the display panel 100, and the opaque ink layer 1000 covers the edge portion of the protective cover plate 300. The opaque ink layer 1000 can be used to form the frame of the display module 000, and to shield the driving circuit and the connection traces in the display module 000, so as to achieve the purpose of beauty.
[0064] In this case, the edge of the protective cover plate 300 covered by the opaque ink layer 1000 is located in a non-light-transmitting area. Therefore, the protective cover plate 300 has a central light-transmitting area 310 and an opaque area 320 located around the central light-transmitting area 310. It should be noted that the display panel 100 has a display area S1 and a non-display area S2 located around the display area S1. The central light-transmitting area 310 of the protective cover plate 300 covers the display area S1 of the display panel 100, and the light emitted from the display area S1 of the display panel 100 can pass through the central light-transmitting area 310 of the protective cover plate 300 and be emitted, so that the display module 000 can normally display a picture.
[0065] It should be noted that, since the side of the polarizing sheet 200 close to the panel bending part 130 is inwardly recessed, in the first direction x, the side of the polarizing sheet 200 close to the panel bending part 130 has a second gap K2 between the boundary of the central light-transmitting area 310 close to the panel bending part 130. Here, the first direction x is parallel to the first panel part 110 and perpendicular to the bending axis of the panel bending part 130.
[0066] wherein, in the first direction x, the width of the second gap K2 is less than or equal to the width of the first gap K1. For this purpose, the area of the first gap K1 that does not overlap with the second gap K2 can be blocked by the light-shielding ink layer 1000, and in order to avoid the metal traces in the display panel 100 from leaking through the area of the first gap K1 that overlaps with the second gap K2, the orthographic projection of the light-shielding part 400 on the protective cover plate 300 at least covers the orthographic projection of the second gap K2 on the protective cover plate 300, so that the light-shielding part 400 can effectively shield the metal traces in the display panel 100 that are not shielded by the light-shielding ink layer 1000, thereby achieving an aesthetic purpose.
[0067] It should also be noted that, in order to avoid the possibility that the width fluctuation of the second gap K2 caused by the bonding tolerance during the bonding of the polarizing sheet 200 and the protective cover plate 300 causes the orthographic projection of the light-shielding part 400 on the protective cover plate 300 to fail to completely cover the orthographic projection of the second gap K2 on the protective cover plate 300, and thus the light-shielding part 400 fails to effectively shield the metal traces in the display panel 100 that are not shielded by the light-shielding ink layer 1000. The orthographic projection of the light-shielding part 400 on the protective cover plate 300 covers the orthographic projection of the first gap K1 on the protective cover plate 300. In this way, the light-shielding part 400 completely shields the metal traces in the display panel 100 that can leak through the first gap K1, further beautifying the appearance of the display module 000.
[0068] In the present application, as shown in Figure 3 in the first direction x, the side of the polarizing sheet 200 close to the panel bending part 130 is flush with the boundary of the display area S1 close to the panel bending part 130.
[0069] In this case, the width of the first gap K1 between the part of the protective adhesive 500 on the first panel part 110 and the polarizing sheet 200 is larger, further avoiding the possibility of contact between the polarizing sheet 200 and the protective adhesive 500. In this way, the optical adhesive layer 600 and the polarizing sheet 200 do not produce bubbles after bonding, making the display effect of the display module 000 better.
[0070] Alternatively, please refer to Figure 4 , Figure 4is a schematic diagram of a film layer structure of a display module provided by an embodiment of the present application. In the first direction x, the polarizing sheet 300 protrudes from the display area S1 toward the boundary of the panel bending part 130.
[0071] In this case, the adhesion tolerance generated in the process of bonding the polarizing sheet 300 and the display panel 100 can be effectively avoided to cause the polarizing sheet 300 to not completely cover the display area S1 in the display panel 100, thereby effectively reducing the reflectivity of the display area S1 of the display panel 100 to ambient light, so as to ensure that the display effect of the picture displayed in the display area S1 of the display panel 100 is better.
[0072] In the embodiment of the present application, the light shielding part has various optional implementation manners, and the present application is illustratively described by taking the following two optional implementation manners as examples.
[0073] The first optional implementation manner, please refer to Figure 5 , Figure 5 is a schematic diagram of a film layer structure of a display panel provided by an embodiment of the present application. The light shielding part 400 is integrated in the inside of the display panel 100 and distributed in the non-display area S2.
[0074] In this case, the display panel 100 includes a driving backboard 101, a light emitting device 102, an encapsulation layer 103 and a cover layer 104.
[0075] The light emitting device 102 in the display panel 100 is located on one side of the driving backboard 101, and the light emitting device 102 is distributed in the display area. The number of the light emitting device 102 in the display panel 100 is multiple, and the multiple light emitting devices 102 can be electrically connected with the driving backboard 101. The driving backboard 101 can drive the multiple light emitting devices 102 to emit light, so that the display panel 100 can display a corresponding picture.
[0076] The encapsulation layer 103 in the display panel 100 is located on the side of the driving backboard 101 away from the light emitting device 102. The encapsulation layer 103 can be used to encapsulate each light emitting device 102, so that water and oxygen in the external environment are not easy to corrode into the inside of the light emitting device 102, and the light emitting device 102 is not damaged.
[0077] The cover layer 104 in the display panel 100 is located on the side of the encapsulation layer 103 away from the driving backboard 101, and the cover layer 104 is at least located in the display area S1, so as to ensure the flatness of the light emitting side of the display panel 100.
[0078] The light shielding part 400 in the display panel 100 is located on the side of the encapsulation layer 103 away from the driving backboard 101, and the light shielding part 400 is distributed in at least part of the cover layer 102, for example, Figure 5The light shielding part 400 is shown to be distributed in the same layer as the cover layer 102.
[0079] Here, Figure 5 The display panel 100 shown in the display module 000 can be Figure 4 The display panel 100 shown in the display module 000 can be Figure 4 As shown, the non-display area S2 close to the panel bending part 130, the panel bending part 130 and the second panel part 130 in the first panel part 110 in the display panel 100 can all be distributed with the light shielding part 400, and the orthographic projection of the first gap K1 on the display panel 100 is located in the area where the light shielding part 400 is located. In this way, the light shielding part 400 can cover at least part of the metal traces in the display panel 100 located in the non-display area S2, especially the metal traces in the area where the orthographic projection of the first gap K1 on the display panel 100 overlaps with the non-display area S2, thereby achieving the purpose of aesthetics.
[0080] It should be noted that, please refer to Figure 6 , Figure 6 is another film layer structure diagram of a display panel provided by the embodiment of the present application. The light shielding part 400 is distributed in the same layer as part of the cover layer 102. That is, part of the cover layer 102 can cover the light shielding part 400, so as to effectively ensure the flatness of the display panel 100.
[0081] It should be noted that, as shown in Figure 5 and Figure 6 The display panel 100 can further include a touch layer 105. The touch layer 105 in the display panel 100 is located between the encapsulation layer 103 and the cover layer 104 in a direction perpendicular to the driving backboard 101. In this case, the light shielding part 400 is located on the side of the touch layer 105 away from the driving backboard 101, and the light shielding part 400 can cover the touch metal traces, especially the touch metal traces in the area where the orthographic projection of the first gap K1 on the display panel 100 overlaps with the non-display area S2, thereby achieving the purpose of aesthetics.
[0082] Among them, the touch layer 105 in the display panel 100 can include a first metal touch layer 105a, a second metal touch layer 105b, and a touch insulating layer 105c located between the first metal touch layer 105a and the second metal touch layer 105b.
[0083] Here, one of the first metal touch layer 105a and the second metal touch layer 105b can include a plurality of first touch electrodes and a plurality of second touch electrodes arranged in the same layer, and a connection electrode for connecting two adjacent distributed first touch electrodes; the other of the first metal touch layer 105a and the second metal touch layer 105b can include a cross electrode for connecting two adjacent distributed first touch electrodes.
[0084] It should be noted that the cross-over electrode and the connecting electrode can be cross arranged, and the two can be insulated by the touch insulation layer 105c. Among them, one of the first touch electrode and the second touch electrode can be a touch driving electrode, and the other can be a touch sensing electrode. Through the cooperation of the touch driving electrode and the touch sensing electrode, the display panel can have a touch function.
[0085] It should also be noted that the touch driving electrode and the touch sensing electrode are both grid-shaped electrodes with a plurality of grid holes. That is, the first metal touch layer 105a has a plurality of first grid holes, and the plurality of first grid holes correspond one-to-one to the plurality of light emitting devices 102, and the orthographic projection of the light emitting device 102 on the driving backboard 101 is located within the orthographic projection of the corresponding first grid hole on the driving backboard 101; the second metal touch layer 105b has a plurality of second grid holes, and the plurality of second grid holes correspond one-to-one to the plurality of light emitting devices 102, and the orthographic projection of the light emitting device 102 on the driving backboard 101 is located within the orthographic projection of the corresponding second grid hole on the driving backboard 101. And in order to ensure that the touch layer 105 will not block the light emitted by the light emitting device 102, the touch insulation layer 105c can be made of a light-transmitting material. In this way, the light emitted by the light emitting device 102 can pass through the corresponding first grid hole, the touch insulation layer 105c and the corresponding second grid hole to be emitted, so as to ensure that the light emitted by the light emitting device 102 will not be blocked by the touch layer 105.
[0086] In this application, as shown in Figure 4 The optical adhesive layer 600 in the display module 000 includes a first part 610 and a second part 620. Among them, the first part 610 in the optical adhesive layer 600 is located between the polarizing plate 200 and the protective cover plate 300, and is bonded with the polarizing plate 200 and the protective cover plate 300 respectively. The second part 620 in the optical adhesive layer 600 is located between the first panel part 130 and the protective cover plate 300, and is bonded with the first panel part 130 and the protective cover plate 300 respectively.
[0087] Among them, the second part 320 is at least distributed in the first gap K1, and the thickness of the second part 320 is greater than the thickness of the first part 310, and the second part 320 is in contact with the protective adhesive 500. In this way, the polarizing plate 200 and the protective adhesive 500 are further prevented from contacting, and the optical adhesive layer 600 and the polarizing plate 200 are bonded without air bubbles, so that the display effect of the display module 000 is better.
[0088] The second alternative embodiment, please refer to Figure 7 , Figure 7Fig. 6 is a schematic view of a film layer structure of another display module according to an embodiment of the present application. The light shielding part 500 in the display module 000 is located between the first panel part 110 and the protective cover plate 300, and is bonded to the first panel part 110 and the protective cover plate 300, respectively. In this case, the optical adhesive layer 600 is located between the polarizer 200 and the protective cover plate 300, and is bonded to the polarizer 200 and the protective cover plate 300, respectively.
[0089] In the above embodiment, the light shielding part 400 is distributed in the first gap K1, and the thickness of the light shielding part 400 is greater than the thickness of the optical adhesive layer 600. The light shielding part 400 is in contact with the protective adhesive 500. In this way, the polarizer 200 and the protective adhesive 500 are further prevented from being in contact, and the optical adhesive layer 600 and the polarizer 200 are not prone to generating bubbles after being bonded, so that the display effect of the display module 000 is better.
[0090] In summary, the display module provided by the embodiments of the present application has the first gap between the part of the protective adhesive located on the first panel part and the polarizer, so that the polarizer and the protective adhesive are not in contact. In this way, the protective adhesive will not exceed the surface of the polarizer due to the siphon effect during the process of coating the protective adhesive on the first panel part. In this case, even if the thickness of the optical adhesive layer is small, the polarizer and the protective adhesive are not in contact, and the protective adhesive will not exceed the surface of the polarizer, so that the optical adhesive layer and the polarizer are not prone to generating bubbles after being bonded, so that the display effect of the display module is better. In addition, in order to prevent the metal traces in the display panel from leaking out through the first gap, the orthogonal projection of the light shielding part on the protective cover plate intersects with the orthogonal projection of the first gap on the protective cover plate, so that the light shielding part can effectively shield the metal traces in the display panel, achieving an aesthetic purpose.
[0091] The embodiments of the present application also provide a display device. The display device can include a frame and a display module connected to the frame. The display module is the display module 000 shown in Figs. 1 to 6. Figures 2 to 4 、 Figure 7 The display device can be any product or component with a display function, such as electronic paper, a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator, etc.
