[0040] The features and exemplary embodiments of the various aspects of the present application will be described in detail below with reference to the drawings. The following detailed description is merely provided to explain the present application in more detail. The present application is not limited to the specific details of the embodiments described herein. The present application can be implemented without some of the specific details of the embodiments. The following description of the embodiments is merely provided to provide a better understanding of the present application by showing examples of the present application.

[0041] It should be noted that, in the present document, the terms such as first and second are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Also, the terms “comprises”, “comprising”, or any other variations thereof are intended to cover a non-exclusive inclusion, so that a process, method, article, or apparatus that comprises a list of elements does not include only those elements, but also other elements not expressly listed or inherent to such process, method, article, or apparatus. Without more limitations, the elements defined by the phrase “comprises” do not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the elements.

[0042] It should be understood that when describing the structure of a component, when one layer, one region is referred to as being located "on" or "above" another layer, another region, it can mean being directly located above the other layer, the other region, or other layers or regions are also included between it and the other layer, the other region. And if the component is turned over, the layer, the region will be located "under" or "below" the other layer, the other region.

[0043] With the development of flexible display technology, flexible display modules have become the development trend of future display terminals. In order to bring users a better use experience, full screen, narrow frame, curl wearing and / or folding, active pen and passive pen and other features will become an important development direction of future flexible display technology.

[0044] Touch function is one of the necessary technologies of flexible display module. According to the use scene, it is divided into active pen and passive pen (including finger) two schemes, and the same series of products usually have products of the two technical schemes at the same time, because the active pen scheme is more high-end and high additional value, mainly reflected in computer drawing high-quality pictures and high comfortable writing feeling. Usually, the active pen scheme adopts 2T2R mode, 2T2R adopts double antenna technology, two lines are responsible for receiving and sending respectively, that is, double-channel transmission, for example, the interaction between the active pen which can actively send signals and the display panel and the display panel; the passive pen is 1T1R mode, that is, single-channel transmission, for example, the touch interaction between the finger and the display panel.

[0045] In the prior art, the active pen scheme and the passive pen scheme cannot share the same flexible display module. And because the active pen has higher requirements for signal quantity, it is necessary for the same flexible display module to be compatible with the two touch design schemes in order to reduce the cost.

[0046] To solve the above problems, the embodiments of the present application provide a flexible display module and a display device, which will be described below in conjunction with the drawings.

[0047] Please refer to Figure 1 and Figure 2 , Figure 1 is a top view schematic diagram of a flexible display module provided by the first aspect embodiment of the present application; Figure 2 is a partial sectional view of a flexible display module provided by the first aspect embodiment of the present application. The flexible display module 10 can be an organic light emitting diode (OLED) display module.

[0048] As Figure 1 and Figure 2As shown, the first aspect of the present application provides a flexible display module 10, which comprises a flexible display panel 100 and an organic adhesive layer 200. The flexible display panel 100 comprises a first part 110, a second part 120, and a bending part 130 connecting the first part 110 and the second part 120, the first part 110 comprises a main body part 112 and an extension part 111 extending from the main body part 112 towards the bending part 130 along a first direction X, and the bending part 130 is located between the extension part 111 and the second part 120; the organic adhesive layer 200 is arranged on one side of the bending part 130 in a thickness direction Z of the flexible display module 10.

[0049] According to the flexible display module 10 provided by the embodiments of the present application, the flexible display module 10 comprises a flexible display panel 100 and an organic adhesive layer 200. The flexible display panel 100 comprises a first part 110, a second part 120, and a bending part 130. The bending part 130 connects the first part 110 and the second part 120, so that the flexible display panel 100 can be bent at the bending part 130, and the first part 110 and the second part 120 are close to each other, thereby reducing the frame size of the flexible display module 10 and realizing a narrow frame design. The first part 110 comprises a main body part 112 and an extension part 111, the main body part 112 is used for light-emitting display of the flexible display module 10. The extension part 111 is arranged to extend towards the bending part 130 along a first direction X, i.e., the extension part 111 is located between the main body part 112 and the bending part 130, and the extension part 111 is arranged to protrude from the main body part 112, so that the bending part 130 is away from the main body part 112. When the flexible display panel 100 is cut subsequently to realize a passive pen scheme, the extension part 111 can be cut, thereby avoiding carbonization of the organic adhesive layer 200 at the position of the bending part 130 caused by cutting of the bending part 130, and improving the problem of failure of the flexible display module 10 caused by carbonization of the organic adhesive layer 200. When the flexible display module 10 is bent at the bending part 130, the organic adhesive layer 200 is used to adjust the neutral layer at the bending part 130, so that the film layer in which the trace is arranged is close to or located at the neutral layer, thereby improving the stress of the trace. The organic adhesive layer 200 is located on one side of the bending part 130 in the thickness direction Z, and the extension part 111 is not provided with the organic adhesive layer 200, so that when the extension part 111 is cut, the problem of carbonization of the organic adhesive layer 200 does not occur. While being compatible with an active pen cutting scheme, the flexible display module 10 can be compatible with a passive pen cutting scheme, i.e., both the active pen scheme and the passive pen scheme can use the flexible display module 10.

[0050] Please refer to Figure 3 , Figure 3 is a top view of a flexible display module provided by another embodiment.

[0051] As Figure 3As shown, in some optional embodiments, the flexible display module 10 comprises a first cutting track 11 extending along the second direction Y, the first cutting track 11 is located at the extension 111, and the first direction X and the second direction Y intersect. Figure 3 In the figure, the position of the first cutting track 11 is schematically shown by a dashed line, and the first cutting track 11 does not constitute a structural limitation on the flexible display module provided by the embodiments of the present application.

[0052] In these optional embodiments, the first cutting track 11 extends along the second direction Y and is located at the extension 111. When the flexible display module 10 is cut by the first cutting track 11, since the organic adhesive layer 200 is located at the bending portion 130, the extension 111 is not cut when cut, the organic adhesive layer 200 is not cut, and the problem of carbonization of the organic adhesive layer 200 does not occur, ensuring the normal function of the flexible display panel 100. The flexible display module 10 cut by the first cutting track 11 is suitable for a passive pen scheme.

[0053] Since the touch control trace in the passive pen scheme is located on the side of the flexible display panel 100 away from the light-emitting surface, the excess bending portion 130 and the second portion 120 can be cut off according to the first cutting track 11, which can reduce the frame size of the flexible display module 10.

[0054] Please continue to refer to Figure 3 In some optional embodiments, the flexible display module 10 comprises a second cutting track 12 extending along the second direction Y, the second cutting track 12 is located on the side of the second portion 120 away from the bending portion 130 in the first direction X, and the second cutting track 12 is spaced apart from the second portion 120. Figure 3 In the figure, the position of the second cutting track 12 is schematically shown by a dashed line, and the second cutting track 12 does not constitute a structural limitation on the flexible display module 10 provided by the embodiments of the present application. Figure 3 In the figure, the position of the second cutting track 12 is schematically shown by a dashed line, and the second cutting track 12 does not constitute a structural limitation on the flexible display module 10 provided by the embodiments of the present application.

[0055] In these optional embodiments, the second cutting track 12 is located on the side of the second portion 120 away from the bending portion 130 in the first direction X, and the second cutting track 12 is spaced apart from the second portion 120. When the flexible display module 10 is cut by the second cutting track 12, the extension 111, the bending portion 130 and the second portion 120 can be retained, and the flexible display module 10 cut by the second cutting track 12 is suitable for an active pen scheme. After the flexible display module 10 is cut by the second cutting track 12, the overall frame size is reduced, realizing a narrow frame design.

[0056] Since the touch control trace in the active pen scheme is located on both sides of the flexible display panel 100 in the thickness direction Z and passes through the bending area and the position of the second part 120, the normal function of the touch control trace in the active pen scheme is not affected when cutting off part of the frame according to the second cutting track 12.

[0057] When the flexible display module 10 has both the first cutting track 11 and the second cutting track 12, the cutting and use requirements of the active pen can be met, and the cutting and use requirements of the passive pen can also be met. Both the active pen scheme and the passive pen scheme can use the same flexible display module 10, i.e., the flexible display module 10 disclosed in the present application, which can greatly reduce the process cost.

[0058] Optionally, the distance between the second cutting track 12 and the second part 120 is 0.1mm-0.3mm.

[0059] In these optional embodiments, the distance between the second cutting track 12 and the second part 120 is the minimum distance between the second cutting track 12 and the edge of the second part 120 close to the second cutting track 12 in the first direction X. When the distance between the second cutting track 12 and the second part 120 is greater than or equal to 0.1mm, it is avoided that the distance between the second cutting track 12 and the second part 120 is too small, and when the flexible display module 10 is cut by the second cutting track 12, the cutting laser will damage the edge of the second part 120, so that burrs appear on the edge of the second part 120, affecting the normal use of the flexible display module 10. When the distance between the second cutting track 12 and the second part 120 is less than or equal to 0.3mm, it is avoided that the distance between the second cutting track 12 and the second part 120 is too large, and the cutting amount of the flexible display module 10 is small, and there is a problem that the remaining frame is still large.

[0060] Please refer to Figure 4 , Figure 4 is a partial cross-sectional view of a flexible display module provided by another embodiment.

[0061] As Figure 4 shown, in some optional embodiments, the flexible display module 10 includes a support layer 300, the support layer 300 is located on the side of the first part 110 away from the light-out surface of the flexible display panel 100 in the thickness direction Z, and at least part of the support layer 300 is located on one side of the extension part 111 in the thickness direction Z.

[0062] In these optional embodiments, the support layer 300 is located on one side of the first section 110 in the thickness direction Z, for supporting the first section 110. At least part of the support layer 300 is located on one side of the extension 111 in the thickness direction Z, so that at least part of the extension 111 is supported by the support layer 300. When the flexible display module 10 is bent, the extension 111 does not bend due to the support of the support layer 300, so that the bending starting position is moved to the edge of the bending section 130, to ensure that the flexible display module 10 is bent only in the bending section 130, improving the bending reliability.

[0063] Referring to Figure 5 , Figure 5 is a partial cross-sectional view of a flexible display module provided by another embodiment.

[0064] As Figure 5 shown, in some optional embodiments, the support layer 300 includes a first support layer 310 and a second support layer 320 arranged at intervals, the first support layer 310 is located on the side of the first section 110 in the thickness direction Z away from the light exit surface of the flexible display panel 100, the second support layer 320 is located on the side of the second section 120 in the thickness direction Z away from the light exit surface of the flexible display panel 100, and at least part of the first support layer 310 is located on one side of the extension 111 in the thickness direction Z.

[0065] In these optional embodiments, the first support layer 310 is located on one side of the first section 110 in the thickness direction Z, for supporting the first section 110. The second support layer 320 is located on one side of the second section 120 in the thickness direction Z, for supporting the second section 120. The first support layer 310 and the second support layer 320 support the first section 110 and the second section 120 respectively, to improve the overall strength of the flexible display panel 100. At least part of the first support layer 310 is located on one side of the extension 111 in the thickness direction Z, so that at least part of the extension 111 is supported by the first support layer 310. When the flexible display module 10 is bent, the extension 111 does not bend due to the support of the first support layer 310, so that the bending starting position is moved to the edge of the bending section 130, to ensure that the flexible display module 10 is bent only in the bending section 130, improving the bending reliability.

[0066] Optionally, the first support layer 310 and the second support layer 320 are made of the same material, reducing the cost.

[0067] Optionally, the first support layer 310 and the second support layer 320 have the same thickness, and the first support layer 310 and the second support layer 320 have the same thickness and material, so that the first support layer 310 and the second support layer 320 have the same support capability for the first section 110 and the second section 120, and the first support layer 310 and the second support layer 320 can be prepared at the same time, simplifying the preparation process.

[0068] Please continue to refer to Figure 5 Optionally, the first support layer 310 is located in the first section 110 in the orthographic projection of the flexible display panel 100, and the first support layer 310 only exists on one side of the first section 110, avoiding the first support layer 310 extending to the bending portion 130 affecting the bending of the bending portion 130.

[0069] Optionally, the second support layer 320 is located in the second section 120 in the orthographic projection of the flexible display panel 100, and the second support layer 320 only exists on one side of the second section 120, avoiding the second support layer 320 extending to the bending portion 130 affecting the bending of the bending portion 130.

[0070] Optionally, the minimum distance between the second support layer 320 and the bending portion 130 in the first direction X is equal to the minimum distance between the first support layer 310 and the bending portion 130 in the first direction X, that is, the distance between the edge of the second support layer 320 close to the bending portion 130 and the edge of the bending portion 130 close to the second support layer 320 is the same as the distance between the edge of the first support layer 310 close to the bending portion 130 and the edge of the bending portion 130 close to the first support layer 310. When the flexible display module 10 is bent, the orthographic projection of the second support layer 320 on the first section 110 and the orthographic projection of the first support layer 310 on the first section 110 coincide, and part of the orthographic projection is located in the extension portion 111, so that the bending starting position is moved to the edge of the bending portion 130, to ensure that the flexible display module 10 only bends in the bending portion 130, improving the bending reliability.

[0071] Please refer to Figure 6 , Figure 6 is a partial cross-sectional view of a flexible display module provided in another embodiment.

[0072] As Figure 6 shown, in some optional embodiments, the flexible display module 10 includes a composite film layer 400, the composite film layer 400 is located on the side of the second section 120 away from the light-out surface of the flexible display panel 100 in the thickness direction Z, and the minimum distance between the composite film layer 400 and the bending portion 130 in the first direction X is less than the maximum distance between the extension portion 111 and the bending portion 130 in the first direction X.

[0073] In the optional embodiments, the composite film layer 400 is located on one side of the second sub-section 120 in the thickness direction Z, and provides protection for the flexible display panel 100. The minimum distance between the composite film layer 400 and the bending section 130 in the first direction X is less than the maximum distance between the extension section 111 and the bending section 130 in the first direction X, that is, the distance between the edge of the bending section 130 close to the composite film layer 400 and the edge of the composite film layer 400 close to the bending section 130 is less than the width of the extension section 111 in the first direction X. After the flexible display module 10 is bent at the bending section 130, the projection of at least part of the composite film layer 400 on the first sub-section 110 is located on the extension section 111, so that the bending starting position is moved to the edge of the bending section 130, to ensure that the flexible display module 10 is only bent at the bending section 130, and the bending reliability is improved.

[0074] Optionally, the orthographic projection of the composite film layer 400 on the flexible display panel 100 is located in the second sub-section 120, and the composite film layer 400 only exists on one side of the second sub-section 120, to avoid the composite film layer 400 extending to the bending section 130 affecting the bending of the bending section 130.

[0075] Optionally, the composite film layer 400 is located on the side of the second support layer 320 away from the second sub-section 120 in the thickness direction Z, and the orthographic projection of the composite film layer 400 on the flexible display panel 100 coincides with the orthographic projection of the second support layer 320 on the flexible display panel 100. On the one hand, the composite film layer 400 and the second support layer 320 completely overlap, so that the second support layer 320 can be protected by the composite film layer 400 at each position. On the other hand, the composite film layer 400 and the second support layer 320 can share the same mask, to simplify the preparation process.

[0076] Optionally, the composite film layer 400 comprises a SCF (Super Clean Foam, SCF) assembly, and the SCF assembly comprises an adhesive layer, a buffer layer and a metal layer which are sequentially stacked in the thickness direction Z. The adhesive layer is used to bond the buffer layer and the flexible display panel 100. The buffer layer is used to improve the anti-impact ability of the flexible display module 10. The metal layer further increases the strength and toughness of the flexible display module 10, so that the anti-falling ability of the flexible display module 10 is increased, and the protection of the composite film layer 400 for the flexible display panel 100 is further enhanced.

[0077] The material of the buffer layer is a material with the characteristics of elasticity, light weight, free bending and ultra-thin volume, such as a foam material. The material of the metal layer is a metal material with good ductility, such as a copper foil.

[0078] Please refer to Figure 7 , Figure 7 is a local cross-sectional view of a flexible display module in a bent state provided by the first aspect of the present application.

[0079] As shown in FIG. 1, in some optional embodiments, the flexible display module 10 comprises a spacer 500 arranged along the thickness direction Z, located on the side of the first part 110 away from the light exit surface of the flexible display panel 100 in the thickness direction Z, and the orthogonal projection of the spacer 500 on the flexible display panel 100 is located within the extension part 111. Figure 7 In these optional embodiments, the spacer 500 supports the first part 110 and the second part 120 at the same time, so that after the flexible display panel 100 is bent, the bending part 130 will not be excessively bent, thereby improving the bending reliability of the bending part 130. The orthogonal projection of the spacer 500 on the flexible display panel 100 is located within the extension part 111, that is, the spacer 500 is arranged close to the bending part 130 and supports the extension part 111, so that the bending starting position is moved to the edge of the bending part 130, thereby ensuring that the flexible display module 10 is only bent at the bending part 130, and improving the bending reliability.

[0080] The spacer 500 can be arranged in various ways, for example, the material of the spacer 500 comprises a wave-absorbing material, so that the spacer 500 can play a role of electromagnetic shielding. Alternatively, the material of the spacer 500 further comprises polyethylene terephthalate (PET), polyimide (PI), etc.
