Abstract

The present application discloses a display module and a display device, which belong to the field of display technology. The display module includes: a protective cover plate, a flexible display panel and a support member. Since the support member is provided in the display module, the panel bending portion in the flexible display panel can be supported. Therefore, even if the panel bending portion in the flexible display panel is extended into the bending portion of the protective cover plate, and the panel bending portion is bent as a whole, it can be ensured that the panel bending portion is not easy to warp toward one side of the bending portion in the protective cover plate. In this way, not only can the risk of collision between the panel bending portion in the flexible display panel and the bending portion in the protective cover plate be reduced, but also the frame size of the display module can be effectively reduced, so that the screen-to-body ratio of the display module is higher.

Description

Technical Field

[0002] Current display modules generally include: a flexible display panel, and a protective cover plate located on the light-emitting side of the flexible display panel.

[0003] Among them, the flexible display panel has advantages over the traditional display panel, such as being deformable, bendable and having good flexibility. The protective cover plate located on the light-emitting side of the flexible display panel can play a certain protective role on the flexible display panel. Here, in order to obtain a curved display module, the edge of the protective cover plate can be set as a curved portion with a certain curvature.

[0004] Generally, the portion in the non-display area of ​​the flexible display panel can be bent to ensure that the width of the non-display area of ​​the flexible display panel is small. However, after the bent portion of the flexible display panel is attached to the bent portion of the protective cover, the bent portion of the flexible display panel is very likely to be tilted toward one side of the bent portion of the protective cover. This will not only lead to a high risk of collision between the bent portion of the flexible display panel and the bent portion, but also lead to a larger frame size of the display module.

Therefore, even if the panel bending portion in the flexible display panel is extended into the bending portion of the protective cover plate, and the panel bending portion is bent as a whole, it can be ensured that the panel bending portion is not easy to tilt toward one side of the bending portion in the protective cover plate. In this way, not only can the risk of collision between the panel bending portion in the flexible display panel and the bending portion in the protective cover plate be reduced, but also the frame size of the display module can be effectively reduced, so that the screen-to-body ratio of the display module is higher.

[0028] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0029] Please refer to Figure 1 , Figure 1 Schematic diagram of a display module provided in an embodiment of the present application. The display module 000 may include: a protective cover plate 100 , a flexible display panel 200 and a support member 300 .

[0030] The protective cover plate 100 in the display module 000 may include: a main body 101 extending in a plane, and a curved portion 102 extending in an arc shape and distributed around the main body 101. The curved portion 102 may be fixedly connected to the edge of the main body 101, and the surface of the curved portion 102 may be tangent to the surface of the main body 101. The curved portion 102 in the protective cover plate 100 has a certain curvature, so that the protective cover plate 100 can be a curved protective cover plate, and thus the display module 000 can be a curved display module.

[0031] The flexible display panel 200 in the display module 000 may include: a first panel portion 201 and a second panel portion 202 arranged opposite to each other, and a panel bending portion 203 for connecting the first panel portion 201 and the second panel portion 202. Here, the flexible display panel 200 in the display module 000 may have a display area, and the display area of ​​the flexible display panel 200 may be located in the first panel portion 201. The first panel portion 201 in the flexible display panel 200 may be attached to the main body portion 101 in the protective cover plate 100, and the orthographic projection of at least part of the panel bending portion 203 on the protective cover plate 100 may be located in the area where the curved portion 102 in the protective cover plate 100 is located. In this way, it can be ensured that the protective cover plate 100 can protect the flexible display panel 200 from the front of the flexible display panel 200.

[0032] Since the side of the flexible display panel 200 where the panel bending portion 203 is provided is the binding side of the display module 000, the driving chip can be bound to the second panel portion 202, so that the driving chip can drive the display area of ​​the first panel portion 201 to display the corresponding picture through the second panel portion 202 and the panel bending portion 203. Therefore, when the orthographic projection of at least part of the panel bending portion 203 in the flexible display panel 200 on the protective cover plate 100 is located in the area where the bending portion 102 in the protective cover plate 100 is located, it can be ensured that the panel bending portion 203 in the flexible display panel 200 can extend into the bending portion 102 of the protective cover plate 100, and further, it can be ensured that the frame width of the binding side of the display module 000 is small, so that the overall screen-to-body ratio of the display module 000 is high.

[0033] The support member 300 in the display module 000 may be located between the curved portion 102 in the protective cover 100 and the panel bent portion 203 in the flexible display panel 200. Here, the support member 300 may be disposed in contact with the curved portion 102 and the panel bent portion 203, respectively, and the contact width between the support member 300 and the panel bent portion 203 may be greater than the contact width between the support member 300 and the curved portion 102. In this way, the portion of the panel bent portion 203 extending into the curved portion 102 in the protective cover 100 may be supported by the support member 300. In this case, even if the panel bending portion 203 in the flexible display panel 200 extends to the bending portion 102 in the protective cover plate 100, so that the panel bending portion 203 is bent as a whole, it can also be ensured that the panel bending portion 203 is not easy to warp toward one side of the bending portion 102 in the protective cover plate 100. In this way, not only the risk of collision between the panel bending portion 203 in the flexible display panel 100 and the bending portion 102 in the protective cover plate 100 can be reduced, but also the frame size of the display module 000 can be reduced.

[0034] In summary, the display module provided in the embodiment of the present application includes: a protective cover plate, a flexible display panel and a support member. Since the support member is provided in the display module, the panel bending portion in the flexible display panel can be supported. Therefore, even if the panel bending portion in the flexible display panel is extended into the bending portion of the protective cover plate, so that the panel bending portion as a whole is bent to a certain extent, it can be ensured that the panel bending portion is not easy to warp toward one side of the bending portion in the protective cover plate. In this way, not only the risk of collision between the panel bending portion in the flexible display panel and the bending portion in the protective cover plate can be reduced, but also the frame size of the display module can be effectively reduced, so that the screen-to-body ratio of the display module is higher.

[0035] In the examples of this application, please refer to Figure 2 , Figure 2 It is a structural schematic diagram of another display module provided by an embodiment of the present application. The side of the support member 300 in the display module 000 that contacts the panel bending portion 203 in the flexible display panel 200 can be a curved surface S1, and the curved surface S1 can be in contact with the side of the panel bending portion 203 in the flexible display panel 200 that faces the curved portion 102 in the protective cover plate 100. In this way, it can be ensured that the shape of the side of the support member 300 facing the panel bending portion 203 in the flexible display panel 200 matches the appearance of the panel bending portion 203, so that the contact area of ​​the side of the support member 300 that contacts the panel bending portion 203 in the flexible display panel 200 is larger, thereby making the support member 300 better in supporting the panel bending portion 203 in the flexible display panel 200.

[0036] In the present application, the support member 300 in the display module 000 is in the shape of a long strip, and the length direction of the support member 300 in the display module 000 can be parallel to the bending axis of the panel bending portion 203 in the flexible display panel 200. Here, the support member 300 can be a strip structure with elasticity. For example, the support member 300 can be a rubber material with high strength. In this way, the effect of the support member 300 supporting the panel bending portion 203 in the flexible display panel 200 can be further improved.

[0037] Among them, in the direction parallel to the bending axis of the panel bending portion 203 in the flexible display panel 200, the length of the support member 300 in the display module 000 can be less than or equal to the length of the panel bending portion 203 in the flexible display panel 200. That is, in the direction parallel to the bending axis of the panel bending portion 203 in the flexible display panel 200, the support member 300 will not protrude from the panel bending portion 203 in the flexible display panel 200. In this way, the end of the support member 300 in the display module 000 will not interfere with the components arranged at the corresponding position in the display device integrated with such display module 000, thereby improving the reliability of the display device integrated with such display module 000.

[0038] In the examples of this application, please refer to Figure 3 , Figure 3 300 in the display module 000 can be arranged in a row along the length direction of the support member 300. For example, the multiple support members 300 in the display module 000 can be arranged at intervals along the length direction of the support member 300. In this way, the material required for preparing the support member 300 can be saved, thereby reducing the manufacturing cost of the display module 000.

[0039] Among them, in the direction parallel to the bending axis of the panel bending portion 203 of the flexible display panel 200, the length d1 of the support member 300 in the display module 000 can be greater than or equal to the distance d2 between two adjacent support members 300. In this way, it can be ensured that the distance between two adjacent support members 300 will not affect the support effect of the support member 300 on the panel bending portion 203 of the flexible display panel 200. In this case, it can be ensured that the support effect of the support member 300 on the panel bending portion 203 of the flexible display panel 200 is good, and the materials required for preparing the support member 300 are saved, thereby reducing the manufacturing cost of the display module 000.

[0040] In the examples of this application, please refer to Figure 4 , Figure 4The display module 000 may further include: an optical adhesive layer 400 located between the protective cover plate 100 and the first panel portion 201 of the flexible display panel 200 .

[0041] The orthographic projection of the optical adhesive layer 400 in the display module 000 on the protective cover plate 100 can cover the area where the main body 101 in the protective cover plate 100 is located, and the side of the optical adhesive layer 400 facing the protective cover plate 100 can at least be bonded to the main body 101, and the side of the optical adhesive layer 400 facing the flexible display panel 200 can at least be bonded to the first panel part 201. The optical adhesive layer 400 is usually made of transparent glue (for example, acrylic glue). In this way, it can be ensured that the light emitted by the first panel part 201 in the flexible display panel 200 is emitted after passing through the optical adhesive layer 400 and the protective cover plate 100. In addition, the optical adhesive layer 400 also has good buffering properties. In this way, after the front of the display module 000 is subjected to impact force, the probability of the protective cover plate 100 being smashed can be reduced by the buffering of the optical adhesive layer 400.

[0042] There may be a gap between the optical adhesive layer in the display module 000 and the support member 300 in the display module 000 , but the width of the gap is small, for example, the width of the gap may be less than 0.1 mm. In this way, the support member 300 in the display module 000 will not affect the bonding effect of the optical adhesive layer 400 .

[0043] In the embodiments of the present application, Figure 4 As shown, the side of the support member 300 in the display module 000 that is away from the optical adhesive layer 400 in the display module 000 is an inclined surface S2. That is, the width of the support member 300 can be gradually reduced along the direction from the panel bending portion 203 in the flexible display panel 200 to the bending portion 102 in the protective cover plate 100. In this way, the structural transition of the support member 300 along the direction from the panel bending portion 203 to the bending portion 102 can be smoother and more natural. In addition, it can also be ensured that the width of the side where the support member 300 is bonded to the bending portion 102 in the protective cover plate 100 is smaller, so that it can be ensured that the side of the support member 300 in contact with the bending portion 102 in the protective cover plate 100 will not have wrinkles when fitting, thereby preventing the support member 300 from being loosely fitted between the bending portion 102 in the protective cover plate 100.

[0044] In this application, please continue to refer to Figure 4The display module 000 may further include: a first adhesive layer 500 located between the support member 300 and the curved portion 102 of the protective cover plate 100. Here, the first adhesive layer 500 may be bonded to the support member 300 and the curved portion 102 of the protective cover plate 100, respectively, so that the support member 300 and the curved portion 102 of the protective cover plate 100 may be bonded together through the first adhesive layer 500, so that the connection between the support member 300 in the display module 000 and the curved portion 102 of the protective cover plate 100 is relatively stable.

[0045] In the embodiments of the present application, Figure 4 As shown, the display module 000 may further include: a circular polarizer 600 , a first supporting layer 700 , a mesh adhesive layer 800 , a foam layer 900 , a polyimide film layer 1000 , a copper foil 1100 , a first adhesive layer 1200 , a second supporting layer 1300 and a protective adhesive layer 1400 .

[0046] Among them, the circular polarizer 600 in the display module 000 can be bonded to the side of the first panel portion 201 facing the protective cover 100. The circular polarizer 600 can reduce the reflectivity of the first panel portion 201 to ambient light to ensure that the display area in the first panel portion 201 has a better effect of displaying the picture.

[0047] The first supporting layer 700 in the display module 000 can be bonded to the back side of the first panel portion 201 (ie, the side opposite to the front side of the first panel portion 201). The first supporting layer 700 in the display module 000 can be used to support the first panel portion 201.

[0048] The grid adhesive layer 800 in the display module 000 may be located on a side of the first supporting layer 700 away from the first panel portion 201, and one side of the grid adhesive layer 800 may be bonded to a side of the first supporting layer 700 away from the first panel portion 201. Here, the side of the grid adhesive layer 800 away from the first supporting layer 700 may be bonded to a side of the foam layer 900 facing the first panel portion 201.

[0049] The side of the foam layer 900 in the display module 000 facing away from the first panel portion 201 can be bonded to the polyimide film layer 1000. The side of the polyimide film layer 1000 in the display module 000 facing away from the first panel portion 201 can be bonded to the copper foil 1100. In this way, the side of the copper foil 1100 facing away from the first panel portion 201 can be bonded to the side of the second support layer 1300 facing the first panel portion 201 through the first adhesive layer 1200. The other side of the second support layer 1300 can be bonded to the side of the second panel portion 202 facing the first panel portion 201.

[0050] The protective adhesive layer 1400 in the display module 000 can be used to strengthen the strength of the panel bending portion 203 in the flexible display panel 200 to ensure that the panel bending portion 203 is not easily damaged.

[0051] In the embodiments of this application, please continue to refer to Figure 4 The display module 000 may further include: a first insulating layer 1500 , a wave absorbing layer 1600 , a conductive shielding layer 1700 and a driving chip 1800 .

[0052] Among them, the driver chip 1800 in the display module 000 can be bound and connected with the second panel part 202, and the driver chip 1800 can be located on the side of the second panel part 202 away from the first panel part 201. It should be noted that the panel bending part 203 and the second panel part 202 in the flexible display panel 200 are both integrated with signal wiring. After the driver chip 1800 is bound to the second panel part 202 in the flexible display panel 200, the driver chip 1800 can be electrically connected to these signal wirings, and these signal wirings can also be electrically connected to the sub-pixels in the first panel part 201. In this way, the driver chip 1800 can send a driving signal to the sub-pixels in the first panel part 201 through these signal wirings, so that the sub-pixels in the first panel part 201 can emit light outward, thereby enabling the first panel part 201 to display the corresponding picture.

[0053] The first insulating layer 1500 in the display module 000 can be located on the side of the second panel portion 202 away from the first panel portion 201, and the orthographic projection of the driving chip 1800 on the second panel portion 202 can be located within the orthographic projection of the first insulating layer 1500 on the second panel portion 202. In this way, the driving chip 1800 can be insulated and protected by the first insulating layer 1500.

[0054] The absorbing layer 1600 in the display module 000 may be located on the side of the first insulating layer 1500 away from the first panel portion 201, one side of the absorbing layer 1600 may be bonded to the side of the first insulating layer 1500 away from the first panel portion 201, and the side of the absorbing layer 1600 away from the first insulating layer 1500 may be bonded to the side of the conductive shielding layer 1700 facing the first panel portion 201. The absorbing layer 1600 may reduce the interference of electromagnetic waves on the driving chip 800.

[0055] In the display module 000, at least a portion covering the driver chip 1800 may exist in the conductive shielding layer 1700. For example, the orthographic projection of the driver chip 1800 on the second panel portion 202 may be located within the orthographic projection of the conductive shielding layer 1700 on the second panel portion 202. Here, the conductive shielding layer 1700 can shield the interference of external signals on the signal output by the driver chip 1800, so that the signal output by the driver chip 1800 is relatively stable. Since the driver chip 1800 can be electrically connected to the signal routing in the first panel portion 201 through the signal routing in the second panel portion 202 and the signal routing in the panel bending portion 203, and the signal routing in the first panel portion 201 can also be electrically connected to the sub-pixels in the first panel portion 201. Therefore, the signal output by the driver chip 1800 can be transmitted to the sub-pixels in the first panel portion 201 through these signal routings, so as to control these sub-pixels to emit light normally, so that the first panel portion 201 can display the corresponding picture. When the signal output by the driving chip 1800 is made more stable by the conductive shielding layer 1700 , it can ensure that the display effect of the picture displayed by the first panel portion 201 is better.

[0056] In the embodiment of the present application, first, the support member 300 and the curved portion 102 in the protective cover plate 100 can be bonded together through the first adhesive layer 500. After that, the bent flexible display panel 200 can be bonded together with the protective cover plate 100 through the optical adhesive layer 400, and the side of the support member 300 away from the curved portion 102 is in contact with the panel curved portion 203 in the flexible display panel 200. Through the above steps, the display module 000 provided in the embodiment of the present application can be obtained.

[0057] In summary, the display module provided in the embodiment of the present application includes: a protective cover plate, a flexible display panel and a support member. Since the support member is provided in the display module, the panel bending portion in the flexible display panel can be supported. Therefore, even if the panel bending portion in the flexible display panel is extended into the bending portion of the protective cover plate, so that the panel bending portion as a whole is bent to a certain extent, it can be ensured that the panel bending portion is not easy to warp toward one side of the bending portion in the protective cover plate. In this way, not only the risk of collision between the panel bending portion in the flexible display panel and the bending portion in the protective cover plate can be reduced, but also the frame size of the display module can be effectively reduced, so that the screen-to-body ratio of the display module is higher.

[0058] The embodiment of the present application also provides a display device, which can be any product or component with a display function, such as a mobile phone, a tablet computer, a television, an advertising machine, a display screen, a digital photo frame, a vehicle-mounted terminal, etc. The display device may include: a frame, and a display module connected to the frame, and the display module is any display module in the above embodiments.

[0059] In the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.

[0060] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
