[0004] The present application provides a flexible display screen and an electronic device, which have better use reliability and service life.

[0005] In a first aspect, a flexible display screen is provided, comprising: a flexible display panel; a support layer for supporting the flexible display panel, an edge region of the support layer being provided with a first hole, a normal projection of the first hole on the flexible display panel at least partially covering an alignment mark on the flexible display panel, and a cross section of the first hole in a direction parallel to the support layer being a closed figure.

[0006] According to the technical scheme of the embodiments of the present application, the hole in the support layer for avoiding the alignment mark is set as a closed full hole, and the full hole has a certain support region between the support edge and the full hole, which can support the edge region of the flexible display panel, reduce the bending stress of the flexible display panel after pressing, thereby reducing the probability of screen black spot problem of the flexible display panel under pressing, and improving the display performance, use reliability and service life of the flexible display screen.

[0007] In some possible implementation manners, in the direction parallel to the support layer, the minimum distance between the first hole and the edge of the support layer ranges between 0.3 mm and 0.5 mm.

[0013] In some possible embodiments, the support layer further comprises a second hole, and a projection of the second hole on the flexible display panel covers a camera hole in the flexible display panel, the camera hole being used for accommodating a camera.

[0014] Through the technical scheme of the embodiment of the present application, the second hole can cooperate with the above-mentioned first hole to realize the alignment of the support layer, which is conducive to reducing the number of the first holes in the support layer, ensuring the alignment effect of the support layer, reducing the influence of the first hole on the flexible display panel, and thus further improving the use reliability of the flexible display screen.

[0015] In some possible embodiments, the flexible display screen further comprises a reinforcing layer attached to the support layer, and the reinforcing layer comprises a third hole, and a projection of the third hole on the support layer covers the second hole.

[0020] In some possible embodiments, the edge of the support layer extends outwardly with an outward protruding portion, and at least part of the first hole is arranged in the outward protruding portion.

[0021] Through the technical scheme of the embodiment, the occupation of the first hole to the internal space of the support layer can be reduced, and the display area of the display screen is preferentially guaranteed.

[0022] In some possible embodiments, the first hole is located between the normal projection of the display area of the flexible display panel on the support layer and the edge of the support layer.

[0023] In the embodiment, the first hole and the alignment mark can be arranged corresponding to the display area of the flexible display panel, so that the support layer and the display area can be effectively aligned, the support layer can play a better supporting role on the display area, and the use performance and display performance of the display area are guaranteed.

Furthermore, the terms "first," "second," etc., in the specification and claims of this application or the aforementioned drawings are used to distinguish different objects, and not to describe a specific order or primary / secondary relationship.

[0040] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0041] In the description of this application, directional terms refer to the directions shown in the figures and are not intended to limit the specific structure of this application. It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly.

[0043] This application relates to displays, and more specifically, to flexible displays. These flexible displays can be applied to a variety of fields and scenarios. For example, they can be applied to 3C electronic products in the computer, communication, and consumer electronics sectors, including but not limited to televisions, mobile phones, computers, laptops, tablets, personal digital assistants (PDAs), in-vehicle computers, wearable devices, gaming devices, and photographic equipment. This application does not limit the specific type of electronic device in which the display is located.

[0044] In addition, the flexible display screen involved in this application can be an organic light-emitting diode (OLED) display screen, a low-temperature polycrystalline silicon (LTPS) OLED display screen, an oxide OLED display screen, a micro OLED display screen, etc. This application does not limit the specific type of the display screen.

[0045] Figure 1 A schematic structural diagram of a flexible display screen provided in an embodiment of this application is shown.

[0046] like Figure 1 As shown, the flexible display screen 100 may include the following layers stacked in sequence: a support layer 110, a back film 120, a flexible display panel 130, a polarizing layer 140, an optical adhesive layer 150, and a cover layer 160.

[0047] exist Figure 1 In this example, the support layer 110 may be referred to as a bracket (BKT). The support layer 110 may have high mechanical strength to provide better support and protection for the flexible display panel 130. In some examples, the support layer 110 may be made of a material that supports folding or bending, thereby enabling a foldable flexible display or a bendable flexible display.

[0048] Back membrane 120 Figure 1 The back film 120, referred to as U-film, is generally thin and can provide some protection for the flexible display panel 130.

[0049] The flexible display panel 130 can be, for example, a flexible OLED display panel. Unlike traditional rigid substrates, this flexible OLED display panel can use flexible materials such as plastic or metal sheets as substrates, such as polyimide (PI).

[0050] Other optical structures can be further provided above the flexible display panel 130 (i.e., on the light-emitting side of the flexible display panel 130) to meet the optical and other requirements of the display screen. For example, such as Figure 1 As shown, a polarizer (POL) layer 140, an optically clear adhesive (OCA) layer 150, and a cover layer 160 may be stacked on top of the flexible display panel 130.

[0051] Figure 1 The diagram shown is merely an illustration of a flexible display screen structure and does not limit the specific structure of a flexible display screen. Figure 1Based on the structure shown, the flexible display screen can be further modified according to actual needs. Figure 1 This may involve adding certain structural elements or other related layers. For details on the specific layer configuration of this flexible display screen, please refer to the relevant technical descriptions; further discussion is not provided here.

[0052] During the manufacturing process of flexible displays, alignment marks can be set on the flexible display panel to facilitate accurate alignment between the support layer and the flexible display panel, thereby providing comprehensive and reliable support and protection for the flexible display panel. To achieve this alignment function, holes need to be made in the support layer to avoid obstructing the alignment marks on the flexible display panel.

[0053] As an example, Figure 2 A schematic plan view of a support layer 110 is shown. Figure 3 The following was shown Figure 2 A schematic enlarged view of the local area A where the middle half-hole 111 is located.

[0054] like Figure 2 and Figure 3 As shown, the support layer 110 has U-shaped semi-holes 111 at its four corners to avoid alignment marks on the flexible display panel. The semi-holes 111 are located at the edges of the support layer 110. Optionally, the semi-holes 111 and the alignment marks can correspond to the active area (AA) of the flexible display panel, thereby ensuring effective alignment between the support layer 110 and the AA area and providing optimal support for the AA area. The AA area may include the display area of ​​the flexible display panel 210.

[0055] for Figure 2 and Figure 3 In the technical solution of the embodiment shown, when the consumer vigorously wipes the screen or presses the location of the half-hole 111 during use, the area where the half-hole 111 is located can be regarded as a stress concentration point. The flexible display panel is deformed by the extrusion force, which causes the half-hole 111 in the support layer 110 to damage the traces of the flexible display panel (such as the traces in the AA area), forming cracks and other defects, which in turn cause black spots on the screen. The professional term is GDSH (Grow Dark Spot in the Hole) phenomenon.

[0056] In view of this, this application provides a flexible display screen that improves the openings in the support layer to mitigate the aforementioned defects such as GDSH, thereby enhancing the display performance, reliability, and lifespan of the flexible display screen.

[0057] Figure 4A partial schematic structural diagram of a flexible display screen 200 provided in an embodiment of this application is shown. Figure 5 It shows Figure 4 A schematic top view of the embodiment shown.

[0058] like Figure 4 and Figure 5 As shown, the flexible display screen 200 includes a flexible display panel 210 and a support layer 220. The support layer 220 is used to support the flexible display panel 210. A first hole 221 is provided in the edge region of the support layer 220. The orthographic projection of the first hole 221 on the flexible display panel 210 at least partially covers the alignment mark 211 on the flexible display panel 210. The cross-section of the first hole 221 in the direction parallel to the support layer 220 is a closed shape.

[0059] In this embodiment, the support layer 220 may at least cover the AA area of ​​the flexible display panel 210, which may include the display area of ​​the flexible display panel 210. Furthermore, the edge of the support layer 220 may substantially coincide with the edge of the flexible display panel 210, or the edge of the support layer 220 may be slightly wider or slightly narrower than the edge of the flexible display panel 210.

[0060] Optionally, in this embodiment, the material of the support layer 220 may include at least a carbon fiber layer, which has high mechanical strength and flexibility, and can provide better support for the flexible display panel 210. Optionally, the support layer 220 may include one or more carbon fiber layers.

[0061] The flexible display panel 210 has alignment marks 211 on the side facing the support layer 220 for aligning the support layer 220. Figure 4 and Figure 5 The alignment mark 211 is illustrated using "*" as an example. In actual applications, the alignment mark 211 can also be designed as other symbols or forms according to requirements. This application embodiment does not specifically limit this.

[0062] The support layer 220 has a first hole 221 corresponding to the alignment mark 211. During the process of attaching the support layer 220 to the flexible display panel 210, the alignment machine can observe the alignment mark 211 in the flexible display panel 210 through the first hole 221, thereby achieving alignment and attachment between the support layer 220 and the flexible display panel 210. After the support layer 220 is attached to the flexible display panel 210, the orthographic projection of the first hole 221 onto the flexible display panel 210 at least partially covers the alignment mark 211 on the flexible display panel 210. Figure 5In the embodiment shown, the orthographic projection of the first hole 221 onto the flexible display panel 210 can completely cover the alignment mark 211 on the flexible display panel 210.

[0063] Furthermore, in this embodiment, the first hole 221 is designed as a full-hole structure, meaning that the cross-section of the first hole 221 in the direction parallel to the support layer 220 is a closed shape. Compared to Figure 2 In the illustrated embodiment, the edge of the first hole 221 of the full-hole structure does not contact the edge of the support layer 220, but has a certain distance from the edge of the support layer 220. This distance can form a certain range of support area for supporting the edge area of ​​the flexible display panel.

[0064] By using the technical solution of this application embodiment, the hole in the support layer used to avoid the alignment mark is set as a closed full hole. There is a certain support area between the full hole and the support edge, which can support the edge area of ​​the flexible display panel, reduce the bending stress generated by the flexible display panel after pressing, thereby reducing the probability of the flexible display panel generating screen black spots under pressing, and improving the display performance, reliability and service life of the flexible display screen.

[0065] As an example, the above Figure 4 and Figure 5 The first hole 221 can be a circular hole, or in some alternative embodiments, the first hole 221 can also be an elliptical hole, a square hole, or other irregularly shaped holes, etc. The embodiments of this application do not limit the specific shape of the first hole 221, and aim to design it as a full hole structure.

[0066] In some embodiments, the minimum distance between the first hole 221 and the edge of the support layer 220 in the direction parallel to the support layer is between 0.3 mm and 0.5 mm, that is, the minimum distance is greater than or equal to 0.3 mm and less than or equal to 0.5 mm.

[0067] As an example, see Figure 5 As shown, the first hole 221 is disposed near one side of the support layer 220, which can be referred to as the first side. The distance D1 between the first hole 221 and the first side is less than the distance between the first hole 221 and the other sides. The distance D1 between the first hole 221 and the first side is between 0.3 mm and 0.5 mm.

[0068] Optionally, in the direction parallel to the support layer, the minimum distance between the first hole 221 and the edge of the support layer 220 ranges from 0.3 mm to 0.4 mm. For example, this minimum distance can be 0.33 mm.

[0069] In the technical solution of the implementation method, by controlling the distance between the first hole and the edge of the support layer to be greater than or equal to 0.3mm, the risk of the support layer breaking at the edge of the first hole can be reduced, and the area of ​​the support region of the support layer at the edge of the first hole can be controlled to ensure a better support effect. In addition, controlling the distance within 0.5mm or 0.4mm can prevent the first hole from being too close to the internal space of the support layer, thus ensuring the area of ​​the display area of ​​the display panel.

[0070] In some embodiments, the size of the first hole 221 in the direction parallel to the support layer ranges from 0.2 mm to 0.5 mm, that is, the size of the first hole 221 is greater than or equal to 0.2 mm and less than or equal to 0.5 mm.

[0071] As an example, the first hole 221 is a circular hole, and the diameter of the circular hole can be between 0.2 mm and 0.5 mm as mentioned above. As another example, the first hole 221 is a square hole, and the side length of the square hole can be between 0.2 mm and 0.5 mm as mentioned above. When the first hole 221 is other regular or irregular holes, the maximum size of the first hole 221 in the direction parallel to the support layer can be between 0.2 mm and 0.5 mm as mentioned above.

[0072] Optionally, the size of the first hole 221 in the direction parallel to the support layer can range from 0.2 mm to 0.35 mm. For example, the size of the first hole 221 can be 0.29 mm.

[0073] In the technical solution of this embodiment, by controlling the size of the first hole, on the one hand, it can be ensured that the alignment marks on the flexible display panel are avoided through the first hole to ensure the alignment effect of the support layer. On the other hand, the area of ​​the first hole can be controlled to be small, thereby reducing the overlap area between the first hole and the flexible display panel, reducing the possibility of cracking the display panel and further causing GDSH when the user presses the area where the first hole is located, thereby improving the reliability and service life of the flexible display screen.

[0074] Figure 6 A schematic plan view of another support layer 220 provided in an embodiment of this application is shown.

[0075] like Figure 6 As shown in this embodiment, in addition to the first hole 221, the support layer 220 may also have a second hole 222, which is located in the flexible display panel 210. Figure 6 The orthographic projection on (not shown) covers the camera hole in the flexible display panel, which is used to accommodate a camera.

[0076] In this embodiment, the second hole 222 in the support layer 220 corresponds to the camera setup of the electronic device where the display screen is located. When the camera is embedded in the display screen, the display screen may have a camera hole to accommodate the camera. Optionally, all layers of the display screen except the cover plate may have camera holes.

[0077] Through the technical solution of the embodiments of this application, the second hole can cooperate with the first hole to realize the alignment of the support layer, which helps to reduce the number of first holes in the support layer. While ensuring the alignment effect of the support layer, it reduces the impact of the first hole on the flexible display panel, thereby helping to further improve the reliability of the flexible display screen.

[0078] In some embodiments, the support layer 220 is a rectangular support layer, and at least two first holes 221 are provided on the edge region of the first side of the support layer 220; a second hole 222 is provided close to the second side of the support layer 220, which is opposite to the first side.

[0079] As an example, see Figure 6 As shown, two first holes 221 are provided on the bottom edge region of the support layer 220, and the two first holes 221 are provided close to the corners of the support layer 220; the second hole 222 is provided close to the top edge of the support layer 220.

[0080] The technical solution of this embodiment can better utilize the first and second holes to achieve the alignment of the support layer on the flexible display panel.

[0081] In this embodiment, the rectangular support layer may include a right-angled rectangle or a rounded rectangle, etc. The first side and the second side of the rectangular support layer are two opposite sides, which can be two short sides or two long sides.

[0082] Optionally, in some embodiments, the edge of the support layer 220 extends with an outward protrusion, and at least a portion of the first hole 221 is disposed on the outward protrusion.

[0083] As an example, Figure 7 It shows Figure 6 A schematic enlarged view of region B where the first hole 221 is located in the embodiment shown.

[0084] like Figure 7 As shown, the first hole 221 is disposed close to the first side of the support layer 220, and the corresponding partial edge of the first hole 221 protrudes outward from the other edges of the first side except for the partial edge. Alternatively, the first side of the support layer 220 extends outward with a protrusion 2201, and at least a portion of the first hole 221 may be disposed on the protrusion 2201.

[0085] As an illustration, Figure 7The first hole 221 is a square hole, as described above. Figure 7 The first hole 221 can also be a circular hole or a hole of other shapes.

[0086] Optionally, the size and / or shape of the protrusion 2201 may be related to the size and / or shape of the first hole 221. For example, in Figure 7 In the illustrated embodiment, the protruding edge of the protrusion 2201 is a linear edge to fit the square first hole 221. In other embodiments, the protruding edge of the protrusion 2201 may also be an arc-shaped edge to fit the circular first hole 221.

[0087] The technical solution of this embodiment can reduce the space occupied by the first hole in the internal space of the support layer, and prioritize the display area of ​​the display screen.

[0088] In some embodiments, the first hole 221 may be located between the display area of ​​the flexible display panel 210 and the orthographic projection of the support layer 220 and the edge of the support layer 220.

[0089] Figure 8 Another schematic enlarged view of the area where the first hole 221 is located in the support layer 220 is shown.

[0090] like Figure 8 As shown, the first hole 221 may be located between the orthographic projection of the AA area of ​​the flexible display panel 210 onto the support layer 220 and the edge of the support layer 220. Optionally, the edge of the support layer 220 may include the edge of the outward protrusion.

[0091] In this embodiment, the first hole 221 and the alignment mark can be set corresponding to the AA area of ​​the flexible display panel 210, so that the support layer 220 and the AA area can be effectively aligned, ensuring that the support layer 220 provides better support for the AA area, thereby ensuring the performance of the AA area in use and display.

[0092] In some embodiments, the flexible display screen 200 may further include a reinforcing layer, which can be attached to the support layer 220 to further reinforce the support layer 220, thereby providing a more reliable support for the flexible display panel. The reinforcing layer may be made of metal, such as steel or a metal alloy. The reinforcing layer can be attached to the support layer via an adhesive layer to achieve a stable connection between the two. In the flexible display screen 200, the reinforcing layer and the flexible display panel 210 can be attached to opposite sides of the support layer 220, respectively.

[0093] The area of ​​the reinforcing layer can be set according to actual needs. For example, the reinforcing layer can be disposed in a local area of ​​the support layer 220 to provide further support and reinforcement to that local area. In this embodiment, the reinforcing layer can reinforce the area surrounding the second hole 222 in the support layer 220, thereby enabling the reinforcing layer and the support layer 220 to provide better protection for the camera located in the second hole 222.

[0094] As an example, Figure 9 It shows Figure 6 A schematic enlarged view of region C where the second hole 222 is located in the embodiment shown. Figure 10 A schematic three-dimensional structural diagram of the support layer 220 and the reinforcing layer 230 in this region is shown.

[0095] like Figure 9 and Figure 10 As shown, a second hole 222 is provided in the support layer 220, and a third hole 231 corresponding to the second hole 222 is provided in the reinforcing layer 230. The orthographic projection of the third hole 231 on the support layer 220 covers the second hole 222. The size of the third hole 231 is larger than the size of the second hole 222, and the orthographic projection of the third hole 231 on the support layer 220 can completely cover the second hole 222.

[0096] exist Figure 9 In the middle, since the support layer 220 covers the reinforcement layer 230, the third hole 231 in the reinforcement layer 230 is marked with a dashed line.

[0097] In some examples, the difference between the size of the third hole 231 and the size of the second hole 222 in the direction parallel to the support layer 220 ranges from 0.2 mm to 0.3 mm. For example, when both the third hole 231 and the second hole 222 are circular holes, the difference between the diameter of the third hole 231 and the diameter of the second hole 222 can be greater than or equal to 0.2 mm and less than or equal to 0.3 mm.

[0098] The technical solution of this embodiment designs the third hole in the reinforcing layer corresponding to the second hole to be larger, and the size of 0.2mm to 0.3mm can cover the assembly error between the reinforcing layer and the support layer, thereby preventing the reinforcing layer from overlapping with the second hole due to assembly error, and ensuring that the second hole is used to achieve the alignment effect of the support layer.

[0099] This application also provides an electronic device. Figure 11 A schematic structural block diagram of an electronic device 300 provided in an embodiment of this application is shown.

[0100] like Figure 11 As shown, the electronic device 300 includes: the flexible display screen 200 provided in any of the embodiments described above.

[0101] Optionally, the electronic device 300 may further include a control device that can be used to control the flexible display screen 200 to display.

[0102] It should be understood that the various implementation methods described in this specification can be implemented individually or in combination, and the embodiments of this application are not limited in this respect.

[0103] It should also be understood that exemplary embodiments are described herein with reference to perspective and / or plan views as idealized exemplary drawings.
