[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] In this application, the directions or positional relationships indicated by the terms "inside", "outside", "middle", etc. are based on the directions or positional relationships shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0039] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0040] In addition, the terms "installed", "set", "provided with", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0042] In the related art, the inner screen of the display module of a mobile terminal such as a mobile phone, tablet or smart watch has a relatively fragile liquid crystal layer. When the display screen module of the mobile terminal is impacted by external force, the liquid crystal layer of the inner screen is damaged. In addition, the outer screen of the display screen module of the mobile terminal is usually made of glass. If the outer screen is damaged, the glass residue of the outer screen will also damage the inner screen. The occurrence of the above situations will cause the display function of the display screen to fail, affecting the use of the mobile terminal.

[0043] Based on this, the present application provides a display screen module and a mobile terminal, wherein the display screen module adopts a flexible display component. Since the flexible display component has a certain deformation buffering capacity, it is beneficial to reduce the risk of display failure caused by the display screen module after being impacted. At the same time, considering that the flexible display component is easily deformed and pressed against the circuit board in the mobile terminal when subjected to external force, especially after the middle area of ​​the flexible display component is deformed, it is easy to deform and press against the circuit board in the mobile terminal, resulting in display defects such as bright spots and top printing on the flexible display component, so at least one of the near field communication module and the flexible circuit board is further arranged in the middle area of ​​the display screen module to reduce the force deformation in the middle area of ​​the display screen module. Then, the local force of the flexible display component is dispersed layer by layer through the protective layer, the near field communication module and the flexible circuit board, reducing the overall force deformation of the flexible display component, thereby reducing the risk of display defects caused by the flexible display component pressing against the circuit board in the mobile terminal due to force deformation. In addition, setting the display screen module and the circuit board in the mobile terminal at a distance is beneficial to prevent the display screen module from pressing against the circuit board after deformation, causing display problems such as bright spots and top printing on the display screen module.

[0044] The mobile terminal disclosed in the present application may be a mobile phone, a tablet computer, a smart watch, etc. In order to facilitate the description of the technical solution of the present application, the following mobile terminal takes a smart watch as an example and further describes the technical solution of the present application in combination with the embodiments and drawings.

[0045] Please also see Figure 1 and Figure 2 The present application discloses a mobile terminal 100, including a terminal housing 101, a circuit board 102 and a display screen module 103. The circuit board 102 is disposed in the terminal housing 101, the display screen module 103 is connected to the terminal housing 101, and the display screen module 103 is electrically connected to the circuit board 102.

[0046] It is understandable that the display screen module 103 can be used in the mobile terminal 100 to realize functions such as display and touch. That is to say, when the user uses the mobile terminal 100, the display screen module 103 is often pressed by the user, and the display screen module 103 is a part that is susceptible to collision when it is hit by the mobile terminal 100. Considering that the display screen module 103 is susceptible to external impact, in order to avoid the display failure caused by damage to the display screen module 103 due to external force, the display part of the display screen module 103 adopts a flexible display component 1. By utilizing the flexible characteristics of the flexible display component 1, the external impact force can be partially buffered, so that the flexible display component 1 is not easy to be broken and damaged in the case of bumping, falling or user pressing hard, thereby reducing the risk of display failure.

[0047] The display screen module 103 may be in a circular, polygonal or other shape, which is not specifically limited in this application.

[0048] The display screen module 103 disclosed in the present application will be further described below in conjunction with embodiments and drawings.

[0049] Please also see Figures 3 to 5 The present application also discloses a display screen module 103, comprising a flexible display component 1, a protective layer 2, a near field communication module 4 and a flexible circuit board 5. The protective layer 2 is arranged on the backlight side of the flexible display component 1, the near field communication module 4 is arranged on the side of the protective layer 2 away from the backlight side, and the flexible circuit board 5 is arranged on the side of the near field communication module 4 away from the backlight side. Among them, at least one of the protective layer 2, the near field communication module 4 and the flexible circuit board 5 is arranged corresponding to the middle area 1a of the flexible display component 1. In other words, the flexible display component 1, the protective layer 2, the near field communication module 4 and the flexible circuit board 5 are stacked in sequence along the thickness direction of the display screen module 103.

[0050] As can be seen from the above, in order to avoid the display failure caused by the damage of the display screen module 103 due to external force, the display part of the display screen module 103 adopts a flexible display component 1. By utilizing the soft characteristics of the flexible display component 1, the external impact force is partially buffered, so that the flexible display component 1 is not easy to be broken and damaged in the case of bumping, falling or user pressing hard, thereby reducing the risk of display failure. Considering that when the flexible display component 1 is subjected to external force (for example, being touched or pressed by the user), the external force usually acts on the middle area of ​​the flexible display component, that is, after the middle area 1a of the flexible display component 1 is deformed, it is easy to push against the circuit board 102 in the mobile terminal 100 due to deformation, resulting in bright spots, top printing and other display defects in the flexible display component 1, so at least one of the near field communication module 4 and the flexible circuit board 5 is further arranged in the middle area 1a of the display screen module 103 to reduce the force deformation of the middle area 1a of the display screen module 103.

[0051] In some embodiments, the near-field communication module 4 and the flexible circuit board 5 are both arranged corresponding to the central area 1a of the flexible display component 1, and the area of ​​the central area 1a of the flexible display component 1 covered by the near-field communication module 4 is greater than or equal to the area of ​​the central area 1a of the flexible display component 1 covered by the flexible circuit board 5. The central area 1a of the flexible display component 1 is a stress distribution area. Therefore, setting the near-field communication module 4 and the flexible circuit board 5 corresponding to the central area 1a is conducive to improving the stress deformation of the central area 1a and reducing the deformation of the central area 1a. Of course, it can be understood that in other embodiments, for example, the near-field communication module 4 can be arranged corresponding to the central area 1a, or the flexible circuit board 5 can be arranged corresponding to the central area 1a.

[0052] Further considering the improvement of the overall force of the flexible display assembly 1 by the near field communication module 4 and the flexible circuit board 5, in some embodiments, the near field communication module 4 can completely or nearly completely cover the middle area 1a, and the near field communication module 4 can also at least partially cover the peripheral area 1b located outside the middle area 1a, and the coverage area of ​​the flexible circuit board 5 on the middle area 1a of the flexible display assembly 1 occupies at least half of the middle area 1a. For example, it can occupy one half, two thirds or four fifths. For details, please refer to Figure 6 , where the middle area 1a occupied by the flexible circuit board 5 is one half of the middle area 1a.

[0053] In actual settings, the near field communication module 4 can be used as a force transition part between the central area 1a and the peripheral area 1b, and can transfer part of the external force received by the central area 1a to the peripheral area 1b, so that the protective layer 2 can be used to buffer part of the external force received by the central area 1a. Since at least one-half of the central area 1a is an easily deformable area, the specific shape of the flexible circuit board 5 can be adjusted according to the easily deformable area in the central area to obtain a relatively good protection effect. It can also reduce the setting of redundant flexible circuit boards 5, which is beneficial to reduce the installation space occupied in the terminal housing 101 when the display screen module 103 is installed in the terminal housing 101, and optimize the internal layout of the mobile terminal 100.

[0054] Since the pressing range of the user's finger pressing on the middle part or the impact range of the external impact on the middle area 1a is centered at one point and spreads in a circular manner toward the plane direction of the display screen module 103, the easy deformation range of the middle area 1a is approximately circular. In some embodiments, the middle area 1a is a circular area, and the diameter of the middle area 1a can be 7mm-27mm. It can be seen from this that the near-field communication module 4 and the flexible circuit board 5 should be arranged roughly corresponding to the circular middle area 1a to better buffer and disperse the external force received by the middle area 1a and reduce the deformation of the middle area 1a. Specifically, the diameter of the middle area 1a can be 7mm, 19mm, and 27mm, etc. Such corresponding arrangement of the near-field communication module 4 and the flexible circuit board 5 has a good stress dispersion effect and a buffering effect, and significantly reduces the deformation of the middle area 1a of the flexible display component 1.

[0055] Among them, the thickness of the near field communication module 4 can be 0.10mm-0.20mm, and the thickness of the flexible circuit board 5 can be 0.10mm-0.20mm. Exemplarily, the thickness of the near field communication module 4 can be 0.10mm, 0.15mm and 0.20mm, etc., and the thickness of the flexible circuit board 5 can be 0.10mm, 0.15mm and 0.20mm, etc. Since the near field communication module 4 is made on the display screen module 103, compared with the conventional design of making the near field communication module 4 in the mobile terminal 100, in order to adapt to the display screen module 103, the thickness of the near field communication module 4 and the thickness of the flexible circuit board 5 connected thereto need to be adjusted accordingly. The above thickness setting is conducive to preventing the overall thickness of the display screen module 103 from being too thick and affecting the thickness of the mobile terminal 100.

[0056] Please also see Figure 6 and Figure 8In some embodiments, the flexible display assembly 1 includes a flexible screen 11 and components 12. The backlight side of the flexible screen 11 has a mounting surface, the mounting surface includes a central area 1a and a peripheral area 1b located outside the central area 1a, and the components 12 are at least partially arranged in the peripheral area 1b. In actual stress analysis, it can be seen that the deformation of the peripheral area 1b of the mounting surface is smaller than that of the central area 1a. Since the components 12 (such as resistors, capacitors, etc.) in the flexible display assembly 1 are relatively fragile, in order to avoid damage to the components 12, the components 12 can be arranged in the peripheral area 1b as much as possible. Thereby effectively protecting the components 12 and avoiding display failure or display failure caused by damage to the components 12. Of course, in some embodiments, the components 12 can also be arranged in the central area 1a, or the components 12 can be arranged in the central area 1a and the peripheral area 1b at the same time to reasonably utilize the space of the mounting surface.

[0057] In some embodiments, the protective layer 2 includes at least a first layer 21 and a second layer 22 that overlap each other, the first layer 21 is disposed on the backlight side of the flexible display component 1, and the first layer 21 is an optical layer. On the one hand, the protective layer 2 can be at least two layers to enhance the force buffering effect on the flexible display component 1. Of course, if the thickness of the display screen module 103 can be ensured, a third layer or more layers can be added to enhance the protective effect of the flexible display component 1. On the other hand, the first layer 21 is a protective layer 2 close to the flexible display component 1, and the first layer 21 is an optical layer, which is beneficial to enhance the display effect of the flexible display component 1.

[0058] In some embodiments, the hardness of the first layer 21 is greater than the hardness of the second layer 22, and / or the thickness of the first layer 21 is less than or equal to the thickness of the second layer 22. In practical applications, the force of the display screen module 103 is transmitted from the first layer 21 to the second layer 22, and then to the near field communication module 4 and the flexible circuit board 5. The greater hardness of the first layer 21 is conducive to improving the impact resistance of the overall structure, and the greater thickness of the second layer 22 is conducive to buffering the impact force. It can be seen that the application uses the first layer 21 and the second layer 22 to work together, which is conducive to improving the overall structural strength of the display screen module 103.

[0059] Optionally, the first layer 21 may be a resin layer, and the second layer 22 may be a foam layer. The thickness of the first layer 21 may be 0.06 mm-0.1 mm, and the thickness of the second layer 22 may be 0.10 mm-0.20 mm.

[0060] Exemplarily, the first layer 21 may be specifically BPF resin (bisphenol F epoxy resin) or epoxy resin, etc., and the second layer 22 may be specifically antistatic foam or SCF (Supercritical Fluids) foam, etc. The thickness of the first layer 21 may be specifically 0.06mm, 0.088mm, and 0.10mm, etc., and the thickness of the second layer 22 may be specifically 0.10mm, 0.13mm, 0.15mm, 0.17mm, and 0.20mm, etc. By setting the first layer 21 and the second layer 22 to the above thicknesses, it is beneficial to ensure the overall strength and anti-deformation effect of the display screen module 103 while preventing the overall thickness of the display screen module 103 from being too thick.

[0061] It is understandable that by using different materials to set the first layer 21 and the second layer 22 and combining corresponding thickness design, it is beneficial to improve the force effect of the display screen module 103 while ensuring the overall thickness of the display screen module 103, thereby enhancing the protection effect of the flexible display component 1.

[0062] In some embodiments, the first layer 21 and the second layer 22 correspond to the middle area 1a and at least part of the peripheral area 1b. Preferably, the first layer 21 and the second layer 22 both cover the middle area 1a and the peripheral area 1b, that is, the first layer 21 and the second layer 22 cover the entire mounting surface. Considering that the middle area 1a is susceptible to deformation by external forces and that a large number of components 12 are also arranged in the peripheral area 1b, the first layer 21 and the second layer 22 can be provided in the middle area 1a and the peripheral area 1b to enhance the protective effect of the first layer 21 and the second layer 22 on the flexible display assembly 1.

[0063] Please refer to Figure 7 In some embodiments, when the display screen module is installed in the terminal housing 101, in the thickness direction of the display screen module 103 (the thickness direction can refer to Figure 2In the X direction described in the figure, there is a first gap 11a between the display screen module 103 and the circuit board 102, and the width of the first gap 11a can be 0.36mm-0.45mm. Since the display screen module 103 uses a flexible display component 1 as the display part, in order to buffer the external force, the flexible display component 1 has a certain deformation ability. When the flexible display component 1 is subjected to force, the deformation of the flexible display component 1 along the thickness direction of the display screen module 103 is usually about 0.36mm. In addition, since the display screen module 103 is usually arranged above the circuit board 102, the flexible display component 1 will deform in the direction of the circuit board 102 when pressed, and the flexible display component 1 may come into contact with the circuit board 102. If the force is too large, the flexible display component 1 is easily ejected to produce display defects such as bright spots and top printing, affecting the display effect. Taking this into consideration, a first gap 11a is set between the display screen module 103 and the circuit board 102, and the width of the first gap 11a can be specifically 0.36mm, 0.38mm, 0.40mm, 0.42mm and 0.45mm, etc., so that the width of the first gap 11a is greater than or equal to the deformation of the flexible display component 1 along the thickness direction of the display screen module 103, which is beneficial to prevent the flexible display component 1 from being pushed out by the circuit board 102 to produce display defects such as bright spots and top printing.

[0064] See also Figure 8 , considering that the edge portion of the display screen module 103 has a wiring for electrical connection with the circuit board 102, such circuit wiring is susceptible to static electricity conducted from the terminal housing 101 when the edge portion of the display screen module 103 contacts the side wall of the terminal housing 101. In some embodiments, a second gap 12b is provided between at least part of the outer edge of the display screen module 103 and the side wall of the terminal housing 101, and the second gap 12b is configured to shield static electricity. Specifically, the outer edge of the display screen module 103 with the electrical connection wiring and the side wall of the terminal housing 101 have a second gap 12b. By adopting the second gap 12b, the side wall of the terminal housing 101 and at least part of the outer edge of the display screen module 103 form an insulating area, so that external static electricity cannot be conducted to the wiring portion of the display screen module 103 through the terminal housing 101, weakening or even shielding the influence of external static electricity on the display screen module 103, which is conducive to improving the display effect of the display screen module 103.

[0065] In some embodiments, the protective layer 2 of the display screen module 103 extends to the second gap 12b. It is understandable that the protective layer 2 of the display screen module 103 can be made of materials with antistatic effects such as resin and foam. In this way, the protective layer 2 originally located at the display screen module 103 is extended to the second gap 12b, and the antistatic properties of the protective layer 2 are utilized to form a double antistatic effect between the protective layer 2 and the second gap 12b, further improving the antistatic effect of the outer edge wiring portion of the display screen module 103.

[0066] Specifically, the display screen module 103 further includes a cover plate 3, which is arranged on the light-emitting side of the flexible display assembly 1, and the second gap 12b includes a first sub-gap 121 and a second sub-gap 122 that are interconnected. The edge side of the cover plate 3 and the side wall of the terminal housing 101 form the first sub-gap 121, and the edge side of the flexible display assembly 1 and the side wall of the terminal housing 101 form the second sub-gap 122. The extended portion of the protective layer 2 extends to the second sub-gap 122 and the first sub-gap 121. Specifically, the extended portion of the protective layer 2 is located in the second sub-gap 122, and the edge of the extended portion is at least partially located in the first sub-gap 121. It can be understood that the cover plate 3 of the display screen module 103 can be used to block the flexible display assembly 1. When the cover plate 3 and the display screen module are installed in the terminal housing 101, the edge side of the cover plate 3 and the side wall of the terminal housing 101 form the first sub-gap 121. The first sub-gap 121 can be used as one of the connecting parts between the terminal housing 101 and the external environment, and there may be waterproof and anti-fouling problems at the first sub-gap 121. In this way, the edge of the extended portion of the protective layer 2 is arranged at the first sub-gap 121, and the edge of the extended portion can be used to cover or at least partially cover the first sub-gap 121, which is conducive to optimizing the waterproof and anti-fouling effects of the first sub-gap 121, so as to protect the circuit board 102 in the terminal housing 101.
