The foldable display module comprises a bendable region 13 and a non-bendable region 14, the non-bendable region 14 comprises a first region 141, the antenna plate 12 comprises an antenna coil 15 located in the non-bendable region 14, and the antenna coil 15 comprises a first trace pattern 16 located in the first region 141. The supporting board 11 includes a first supporting portion 17 located in the non-bending region 14, the first supporting portion 17 includes a second trace pattern 18 located in the first region 141, and the second trace pattern 18 includes a hollow portion 181. The second trace pattern 18 covers the first trace pattern 16 in the thickness direction of the support board 11.
Specifically, as shown in fig. 1 to 5, the foldable display module includes a bendable region 13 and a non-bendable region 14, the foldable display module has a foldable state and an unfolded state, and when the foldable display module is in the unfolded state, the bendable region 13 is unfolded to obtain a larger display image, so as to meet the use requirements of multiple scenes and multiple tasks, such as office work, entertainment, and the like. When the foldable display module is in a folded state, the bendable region 13 is bent, so that the portability of the foldable display module can be improved.
Wherein, fold condition can include the state of infolding and/or the state of infolding, when collapsible display module assembly was in under the state of infolding, the district 13 of can buckling to the play plain noodles direction of collapsible display module assembly, and the play plain noodles of collapsible display module assembly was inboard at this moment can play the guard action to going out the plain noodles, reduces the wearing and tearing of collapsible display module assembly under non-user state. When the foldable display module is in an outward folding state, the bendable region 13 bends towards the direction away from the light emitting surface, small-screen display can be achieved, a user can conveniently operate the foldable display module with one hand, and the foldable display module is convenient to use.
It should be noted that, the number and the positions of the bendable regions 13 and the non-bendable regions 14 may be set according to actual requirements, for example, as shown in fig. 1 to 5, the foldable display module may include 1 bendable region 13 and 2 non-bendable regions 14, and the 2 non-bendable regions 14 are respectively located at two opposite sides of the bendable region 13, but not limited thereto, in other embodiments, 2 bendable regions 13 and 3 non-bendable regions 14 may also be set, and the bendable regions 13 and the non-bendable regions 14 are alternately arranged to realize a foldable display module of 3 folds, which is not limited in this embodiment of the present invention.
With continued reference to fig. 1-3, the foldable display module includes a flexible display panel 10 to perform the bending and display functions. The flexible display panel 10 may be a flexible OLED display screen, an LCD display screen, or electronic paper, which is not limited in this embodiment of the present invention.
With continued reference to fig. 1-5, a supporting plate 11 is disposed on a side of the flexible display panel 10 away from the light emitting surface to support the flexible display panel 10, and meanwhile, when the foldable display module is switched between the folded state and the unfolded state, the supporting plate 11 can drive each structure of the foldable display module including the flexible display panel 10 to bend.
The supporting plate 11 may be made of a metal material, such as a metal alloy material, such as stainless steel, titanium alloy, copper alloy, etc., and has a relatively high supporting performance and a relatively low cost, but is not limited thereto.
Optionally, the thickness of the support plate 11 may be 30-300 μm, so that the support plate 11 may be bent while ensuring the support performance, and the support plate may not be too thick. For example, the thickness of the support plate 11 may be further set to 30-200 μm, or the thickness of the support plate 11 may be 30 μm or 150 μm, which can be set by those skilled in the art according to actual requirements.
With continued reference to fig. 1-5, an antenna plate 12 is disposed on a side of the supporting plate 11 away from the flexible display panel 10, the antenna plate 12 may include a substrate 19 and an antenna coil 15 disposed on a side of the substrate 19, and when an object (e.g., a magnet or an electromagnetic pen, etc.) with a magnetic field approaches the foldable display module, a corresponding touch point coordinate may be detected through a change in an induced current in the antenna coil 15, so as to obtain a touch position and implement an electromagnetic touch function.
The number, shape, size, number of turns, and line width of the antenna coil 15 may be set according to actual requirements, which is not specifically limited in the embodiment of the present invention, but it can be understood that structural parameters of the antenna coil 15 may determine a line resistance of the antenna coil 15, and the smaller the line resistance of the antenna coil 15 is, that is, the smaller the driving load is, the larger the variation of the induced current is, the smaller the touch signal delay is, and the higher the touch sensing sensitivity is.
In addition, the antenna board 12 may be only disposed in the non-bending region 14, and the antenna board 12 is not disposed in the bending region 13, for example, as shown in fig. 1 to 5, taking 2 non-bending regions 14 respectively located at two sides of the bending region 13 as an example, the foldable display module includes 2 antenna boards 12, and 2 antenna boards 12 are respectively located in 2 non-bending regions 14, so as to implement the electromagnetic touch function of the non-bending regions 14, and meanwhile, by calculating the change of the induced current in the antenna coils 15 on the 2 antenna boards 12, the coordinates of the bendable touch points of the bending region 13 may also be obtained, thereby implementing the electromagnetic touch function of the bending region 13. By adopting the above scheme, the antenna board 12 does not need to be specially designed, the structure is simple, the implementation is easy, and the cost is reduced, but the antenna board is not limited to the above scheme, and a person skilled in the art can set the number and the positions of the antenna boards 12 according to actual requirements.
Alternatively, an object (e.g., a magnet or an electromagnetic pen) with a magnetic field generally performs a touch operation on the light emitting surface side of the flexible display panel 10, and therefore, the antenna coil 15 may be disposed on the substrate 19 near the supporting plate 11, which is beneficial to reducing the distance between the antenna coil 15 and the object with a magnetic field, thereby improving the touch sensing sensitivity, but is not limited thereto.
Further, the substrate 19 may be a rigid substrate or a flexible substrate. Flexibility, also known as flexibility, is a property of an object in terms of relative rigidity. Flexibility refers to a physical property that an object cannot restore to an original shape after being deformed by a force and losing the force. And after the rigid object is stressed, the shape of the rigid object can be regarded as unchanged in a macroscopic view. Alternatively, the flexible substrate may be a bendable substrate.
Illustratively, the material of the flexible substrate may be ultra-thin glass, metal foil or a polymer plastic material. The ultra-thin glass may include ultra-thin alkali-free glass, the metal foil may include stainless steel foil, aluminum foil, copper foil, etc., and the polymer plastic material may include Polyimide (PI), polyvinyl alcohol (PVA), Polyethylene Terephthalate (PET), etc. The material of the rigid substrate base plate can be glass or silicon wafer. The glass may include aluminosilicate glass, soda lime glass (white glass), green glass, or the like. The above-mentioned flexible substrate materials and rigid substrate materials are merely exemplary and not restrictive.
Optionally, the support plate 11 may be attached to the flexible display panel 10 through a glue material, and the antenna plate 12 may also be attached to the support plate 11 through a glue material, so as to ensure reliability of the foldable display module. The Adhesive material may include any one of an Optically Clear Adhesive (OCA), a Pressure Sensitive Adhesive (PSA), and a frame foam, but is not limited thereto.
With continued reference to fig. 1-5, the antenna coil 15 of the antenna plate 12 may be located in the non-inflection region 14, and the non-inflection region 14 includes a first region 141, where the size of the first region 141 may be the same as the size of the non-inflection region 14, or may be smaller than the size of the non-inflection region 14, which is not limited in the embodiment of the present invention.
With reference to fig. 1 to 5, the antenna coil 15 in the first area 141 has a first trace pattern 16, the portion of the supporting plate 11 in the non-bending area 14 is a first supporting portion 17, the first supporting portion 17 has a second trace pattern 18 in the first area 141, and a hollow portion 181 is disposed in the second trace pattern 18, where the hollow portion 181 is a through hole area formed by hollowing out the first supporting portion 17, and in the hollow portion 181, there is no material of the supporting plate 11. The size of the hollow portion 181 can be the same as the size of the second trace pattern 18, or can be smaller than the size of the second trace pattern 18, and those skilled in the art can set the size according to actual requirements.
With continued reference to fig. 1 to 5, the vertical projection of the second trace pattern 18 on the flexible display panel 10 covers the vertical projection of the first trace pattern 16 on the flexible display panel 10, so that an electromagnetic signal of an object (e.g., a magnet or an electromagnetic pen, etc.) with a magnetic field on the light-emitting surface side of the flexible display panel 10 can pass through the hollow portion 181 of the first trace pattern 16 on the supporting plate 11, and thus the antenna coil 15 can receive the electromagnetic signal through the hollow portion 181 of the first trace pattern 16 on the supporting plate 11 and convert the electromagnetic signal into an electrical signal, thereby implementing accurate interpretation of the position of the object with a magnetic field.
According to the foldable display module provided by the embodiment of the invention, the first area is arranged in the non-bending area, the second wiring pattern comprising the hollow part is arranged on the supporting plate of the first area, and the second wiring pattern covers the first wiring pattern of the antenna coil in the first area along the thickness direction of the supporting plate, so that the antenna coil can receive an electromagnetic signal on one side of the light-emitting surface of the flexible display panel through the hollow part of the first wiring pattern on the supporting plate in the first area, the shielding effect of the supporting plate on the antenna coil is reduced, the electromagnetic touch function is realized, and the problem that the electromagnetic touch function is invalid due to the fact that the electromagnetic signal cannot pass through the supporting plate to reach the antenna coil on the antenna plate in the prior art is solved.
With continued reference to fig. 4 and 5, optionally, the shape of the second trace pattern 18 is the same as the shape of the first trace pattern 16.
The shape of the second trace pattern 18 is the same as the shape of the first trace pattern 16, so that the direction of the hollow portion 181 in the second trace pattern 18 is consistent with the direction of the first trace pattern 16 of the antenna coil 15 in the first region 141, and when the vertical projection of the second trace pattern 18 on the flexible display panel 10 covers the vertical projection of the first trace pattern 16 on the flexible display panel 10, the setting area of the second trace pattern 18 can be reduced, that is, the area of the hollow portion 181 on the supporting plate 11 is reduced, thereby improving the supporting performance of the supporting plate 11.
With continued reference to fig. 4 and fig. 5, optionally, the line width of the first trace pattern 16 is D1, and the line width of the second trace pattern 18 is D2, where D2 ≧ D1.
For example, as shown in fig. 4 and fig. 5, a line width D1 of the first trace pattern 16 may be equal to a line width D2 of the second trace pattern 18, so that while the requirement that the vertical projection of the second trace pattern 18 on the flexible display panel 10 covers the vertical projection of the first trace pattern 16 on the flexible display panel 10 is satisfied, the arrangement area of the second trace pattern 18 may be reduced to the greatest extent, and then the area of the hollow portion 181 on the supporting board 11 is reduced, thereby improving the supporting performance of the supporting board 11.
Fig. 6 is a schematic structural view of another supporting board according to an embodiment of the invention, as shown in fig. 4 and fig. 6, a line width D2 of the second trace pattern 18 may be larger than a line width D1 of the first trace pattern 16 to increase an area of the hollow portion 181, so as to increase an area through which an electromagnetic signal can pass, and to help improve an electromagnetic touch sensing sensitivity of the antenna coil 15.
It can be understood that, on the basis of the line width D1 of the first trace pattern 16, the smaller the line width D2 of the second trace pattern 18 is, the smaller the area of the hollow portion 181 is, and the better the supporting performance of the supporting board 11 is; the larger the line width D2 of the second trace pattern 18 is, the larger the area of the hollow portion 181 is, the larger the area of the region through which the electromagnetic signal can pass is, which is more favorable for improving the electromagnetic touch sensing sensitivity of the antenna coil 15. In the present embodiment, 100% by D1 is not less than D2 is not less than 150% by D1, so that the electromagnetic touch sensing sensitivity of the antenna coil 15 is improved while the supporting performance of the supporting plate 11 is ensured.
Fig. 7 is a schematic diagram of a stacked structure of a supporting board and an antenna board according to an embodiment of the present invention, as shown in fig. 7, optionally, the second trace pattern 18 overlaps the first trace pattern 16 along the thickness direction of the supporting board 11.
As shown in fig. 7, the vertical projection of the second trace pattern 18 on the flexible display panel 10 completely overlaps the vertical projection of the first trace pattern 16 on the flexible display panel 10, so that the vertical projection of the second trace pattern 18 on the flexible display panel 10 covers the vertical projection of the first trace pattern 16 on the flexible display panel 10, and the area of the second trace pattern 18 can be reduced to the greatest extent, thereby reducing the area of the hollow portion 181 on the supporting plate 11, and facilitating to improve the supporting performance of the supporting plate 11.
In other embodiments, when the area of the second trace pattern 18 is larger than the area of the first trace pattern 16, the second trace pattern 18 and the first trace pattern 16 do not overlap along the thickness direction of the supporting board 11.
For example, fig. 8 is a schematic view of another stacked structure of a supporting board and an antenna board according to an embodiment of the present invention, as shown in fig. 8, when the area of the second trace pattern 18 is larger than the area of the first trace pattern 16, the shortest distances between each point on the boundary adjacent to the first trace pattern 16 in the second trace pattern 18 and the first trace pattern 16 may be set to be equal along the thickness direction of the supporting board 11, which is helpful for making the touch performance in the area near the boundary of the first trace pattern 16 consistent, so as to improve the uniformity of the touch performance in the first area 141.
Fig. 9 is a schematic structural view of another supporting board according to an embodiment of the invention, as shown in fig. 3 and fig. 9, optionally, the second trace pattern 18 further includes non-hollow portions 182, and the hollow portions 181 and the non-hollow portions 182 are alternately arranged along an extending direction of the second trace pattern 18.
Specifically, the non-hollow portion 182 is disposed in the second trace pattern 18, the non-hollow portion 182 refers to a region of the second trace pattern 18 that is not processed by hollow processing, as shown in fig. 9, a line width of the non-hollow portion 182 is the same as a line width of the second trace pattern 18, the non-hollow portion 182 is connected to the first supporting portions 17 on two sides of the second trace pattern 18, that is, the non-hollow portion 182 serves to connect the first supporting portions 17 on two sides of the second trace pattern 18, so as to ensure a supporting performance of the first supporting portions 17.
The hollow portions 181 and the non-hollow portions 182 are alternately arranged along the extending direction of the second trace pattern 18, that is, in the second trace pattern 18, one non-hollow portion 182 is arranged at intervals along the extending direction of the second trace pattern 18 for connecting the first supporting portions 17 at two sides of the second trace pattern 18, so as to further improve the supporting performance of the first supporting portions 17.
With reference to fig. 9, optionally, along the extending direction of the second trace pattern 18, the length of the hollow portion 181 is greater than the length of the non-hollow portion 182.
For example, as shown in fig. 9, taking the hollow portion 181 on the upper left of the first supporting portion 17 as an example, the hollow portion 181 includes a vertical section extending along the vertical direction and a horizontal section extending along the horizontal direction, the length of the vertical section is l1, and the length of the horizontal section is l2, so that the length of the hollow portion 181 is l1+ l 2. Similarly, the length of the non-hollow portion 182 refers to the length of the non-hollow portion 182 in the extending direction of the second trace pattern 18.
In this embodiment, by setting the length of the hollow portion 181 in the extending direction of the second trace pattern 18 to be greater than the length of the non-hollow portion 182 in the extending direction of the second trace pattern 18, the supporting performance of the supporting board 11 is ensured, and the length of the hollow portion 181 is ensured, so as to ensure the area of the area through which the electromagnetic signal can pass, which is helpful for improving the electromagnetic touch sensing sensitivity of the antenna coil 15.
It can be understood that the larger the area of the hollow portion 181 in the second trace pattern 18 is, the smaller the shielding effect of the supporting plate 11 on the antenna coil 15 is, the higher the sensitivity of the electromagnetic touch sensing is, but too many hollow portions 181 on the supporting plate 11 may affect the supporting performance of the supporting plate 11, and therefore, in this embodiment, the area of the hollow portion 181 in the second trace pattern 18 may be set to be 70% to 99% of the area of the second trace pattern 18, so that the supporting performance of the supporting plate 11 is ensured, and the sensitivity of the electromagnetic touch sensing of the antenna coil 15 is ensured.
With reference to fig. 9, optionally, along the extending direction of the second trace pattern 18, the length of the hollow portion 181 is L1, where L1 is greater than or equal to 10mm and less than or equal to 60 mm.
For example, as shown in fig. 9, taking the hollow portion 181 at the upper left of the first supporting portion 17 as an example, the length L1 of the hollow portion 181 in the extending direction of the second trace pattern 18 is L1+ L2, in this embodiment, by setting the length L1 of the hollow portion 181 in the extending direction of the second trace pattern 18 to satisfy that L1 is greater than or equal to 10mm and less than or equal to 60mm, that is, along the extending direction of the second trace pattern 18, every 10mm-60mm, a non-hollow portion 182 is disposed to connect the first supporting portions 17 at two sides of the second trace pattern 18, so that the length L1 of the hollow portion 181 is not too long to affect the supporting performance of the supporting board 11, and the length L1 of the hollow portion 181 is not too short to affect the electromagnetic touch sensing sensitivity of the antenna coil 15.
The specific value of the length L1 of the hollow portion 181 in the extending direction of the second trace pattern 18 can be set according to actual requirements, and it can be understood that the longer the length L1 of the hollow portion 181 in the extending direction of the second trace pattern 18 is, the higher the electromagnetic touch sensing sensitivity of the antenna coil 15 is, but the support performance of the support plate 11 is reduced; the shorter the length L1 of the hollow portion 181 in the extending direction of the second trace pattern 18 is, the better the supporting performance of the supporting board 11 is, but the electromagnetic touch sensing sensitivity of the antenna coil 15 is reduced.
With reference to fig. 9, optionally, in the extending direction of the second trace pattern 18, the length of the non-hollow portion 182 is L2, where L2 is greater than or equal to 1mm and less than or equal to 5 mm.
For example, as shown in fig. 9, by setting the length L2 of the non-hollow portion 182 in the extending direction of the second trace pattern 18 to satisfy 1mm ≤ L2 ≤ 5mm, the connection effect of the first supporting portions 17 on the two sides of the second trace pattern 18 is not affected by too short the length L2 of the non-hollow portion 182, and the electromagnetic touch sensing sensitivity of the antenna coil 15 is not affected by too long the length L2 of the non-hollow portion 182.
The specific value of the length L2 of the non-hollow portion 182 in the extending direction of the second trace pattern 18 can be set according to actual requirements, for example, the length L2 of the non-hollow portion 182 in the extending direction of the second trace pattern 18 satisfies 1mm ≦ L2 ≦ 3mm, but is not limited thereto. It can be understood that the shorter the length L2 of the non-hollow portion 182 in the extending direction of the second trace pattern 18 is, the higher the electromagnetic touch sensing sensitivity of the antenna coil 15 is, but the supporting performance of the supporting board 11 is reduced; the longer the length L2 of the non-hollow portion 182 in the extending direction of the second trace pattern 18 is, the better the supporting performance of the supporting board 11 is, but the electromagnetic touch sensing sensitivity of the antenna coil 15 is reduced.
Fig. 10 is a schematic structural view of another antenna board according to an embodiment of the present invention, and fig. 11 is a schematic structural view of another supporting board according to an embodiment of the present invention, as shown in fig. 10 and fig. 11, optionally, the non-bending region 14 further includes a second region 142, the antenna coil 15 includes a third trace pattern 20 located in the second region 142, the first supporting portion 17 includes a non-hollowed-out portion 21 located in the second region 142, and the non-hollowed-out portion 21 covers the third trace pattern 20 along a thickness direction of the supporting board 11.
Specifically, as shown in fig. 10 and 11, the non-bending region 14 further includes a second region 142, and the first supporting portion 17 in the second region 142 is a non-hollow portion 21, that is, the first supporting portion 17 is not hollow in the second region 142. Meanwhile, part of the antenna coils 15 are disposed in the second area 142, and the antenna coils 15 in the second area 142 have the third trace pattern 20, wherein the vertical projection of the non-hollow-out part 21 on the flexible display panel 10 covers the vertical projection of the third trace pattern 20 on the flexible display panel 10, so that the supporting board 11 corresponding to part of the antenna coils 15 is not hollow-out, thereby improving the supporting performance of the supporting board 11.
It can be understood that the larger the range of the first area 141 is, the larger the settable range of the second trace pattern 18 is, and further, the smaller the shielding effect of the supporting board 11 on the antenna coil 15 is, the higher the sensitivity of the electromagnetic touch sensing is; the larger the range of the second region 142, the larger the settable range of the non-pierced work portion 21, and the better the supporting performance of the supporting plate 11. Therefore, in the present embodiment, the area of the second region 142 may be smaller than the area of the first region 141, so as to ensure the supporting performance of the supporting plate 11, and simultaneously ensure the area of the hollow portion 181, so as to ensure the area of the region through which the electromagnetic signal can pass, which is helpful for improving the electromagnetic touch sensing sensitivity of the antenna coil 15, but is not limited thereto.
With continued reference to fig. 9 and 10, optionally, the antenna coil 15 includes a first coil 22, the first coil 22 includes an incoming terminal 221 and an outgoing terminal 222, and the third trace pattern 20 includes an incoming terminal 221 and an outgoing terminal 222.
Specifically, as shown in fig. 9 and 10, the antenna coil 15 includes at least one first coil 22, and the first coil 22 includes a radiation coil 23, and an incoming terminal 221 and an outgoing terminal 222 respectively connected to two ends of the radiation coil 23, where the radiation coil 23 is configured to receive an electromagnetic signal on the light exit surface side of the flexible display panel 10, the incoming terminal 221 may be a positive terminal for receiving a signal, and the outgoing terminal 222 may be a negative terminal for outputting a signal.
Further, since the lead-in terminal 221 and the lead-out terminal 222 are not used for receiving the electromagnetic signal on the light emitting surface side of the flexible display panel 10, in the present embodiment, the third trace pattern 20 is disposed to include the lead-in terminal 221 and the lead-out terminal 222, that is, the area where the lead-in terminal 221 and the lead-out terminal 222 are located is the second area 142, and the vertical projection of the non-hollow part 21 on the flexible display panel 10 covers the vertical projection of the lead-in terminal 221 and the lead-out terminal 222 on the flexible display panel 10, so that the support plate 11 corresponding to the lead-in terminal 221 and the lead-out terminal 222 is not hollow, so as to improve the support performance of the support plate 11.
Fig. 12 is a schematic structural diagram of another support plate according to an embodiment of the present invention, as shown in fig. 12, optionally, the support plate 11 further includes a non-metal support portion 24, and the non-metal support portion 24 is located in the hollow portion 181.
Specifically, non-metal supporting portion 24 adopts non-metal material, and consequently, non-metal supporting portion 24 can not obstruct electromagnetic signal's propagation, as shown in fig. 12, in this embodiment, through filling non-metal supporting portion 24 in fretwork portion 181, when not influencing electromagnetic signal's propagation, non-metal supporting portion 24 can play the effect of connecting the first supporting portion 17 of second line pattern 18 both sides to guarantee the support performance of first supporting portion 17.
Along the thickness direction of the supporting plate 11, the non-metal supporting portion 24 may overlap with the hollow portion 181, that is, the vertical projection of the non-metal supporting portion 24 on the flexible display panel 10 completely overlaps with the vertical projection of the hollow portion 181 on the flexible display panel 10, so as to improve the installation area of the non-metal supporting portion 24 to the greatest extent and improve the supporting performance of the first supporting portion 17, but not limited thereto.
In other embodiments, the non-metal supporting portion 24 may be only disposed in a partial area of the hollow portion 181, so as to reduce the influence of the non-metal supporting portion 24 on the electromagnetic signal, and the supporting performance of the first supporting portion 17 can be improved only by disposing the non-metal supporting portion 24 to be connected with the first supporting portions 17 on two sides of the second trace pattern 18.
Optionally, the material of the non-metal support portion 24 includes a polymer material.
The material of the non-metal supporting portion 24 may be a polymer material such as Polycarbonate (PC), synthetic resin, or the like, and the polymer material may be directly filled in the hollow portion 181 by using an injection molding process to form the non-metal supporting portion 24, which is mature in process, easy to implement, and beneficial to reducing the manufacturing cost, but not limited thereto.
In other embodiments, the material of the non-metal support portion 24 may also be glass, and the non-metal support portion 24 may also be formed by melting the glass at a high temperature and then filling the melted glass in the hollow portion 181, which may be set by a person skilled in the art according to actual requirements.
Fig. 13 is a schematic cross-sectional view taken along the direction B-B' in fig. 12, and as shown in fig. 13, alternatively, the first supporting portion 17 includes a first supporting surface 171 near the flexible display panel, the non-metal supporting portion 24 includes a second supporting surface 241 near the flexible display panel, and the first supporting surface 171 and the second supporting surface 241 are located in the same plane.
Specifically, as shown in fig. 13, taking an example that a flexible display panel (not shown) is located above the first supporting portion 17, by arranging the first supporting surface 171 of the first supporting portion 17 on the side close to the flexible display panel and the second supporting surface 241 of the non-metal supporting portion 24 on the side close to the flexible display panel in the same plane, the first supporting surface 171 and the second supporting surface 241 form a flat plane, which is helpful for improving the supporting performance of the flexible display panel.
With continued reference to FIG. 13, optionally, the thickness of the first support portion 17 is H1, and the thickness of the non-metal support portion 24 is H2, wherein H1 ≧ H2.
For example, as shown in fig. 13, the thickness H2 of the non-metal support 24 may be equal to the thickness H1 of the first support 17, so that the non-metal support 24 and the first support 17 form a flat support plate 11, which helps to improve the support performance of the flexible display panel, but is not limited thereto.
In other embodiments, the thickness H2 of the non-metal support 24 may be smaller than the thickness H1 of the first support 17, so that the first support 17 has good support performance, and the weight of the entire foldable display module is reduced, which is beneficial to improving the portability of the foldable display module.
It should be noted that the thickness of the non-metal support 24 can be set according to practical requirements, for example, the thickness H2 of the non-metal support 24 is greater than or equal to 100 μm to ensure the supporting performance of the flexible display panel.
Fig. 14 is a schematic structural view of another supporting plate according to an embodiment of the present invention, as shown in fig. 14, optionally, the supporting plate 11 further includes a second supporting portion 25 located in the bendable region 13, and the second supporting portion 25 includes a hollow structure 26.
The hollow structure 26 is a through hole region formed by hollowing the second supporting portion 25, and the material of the supporting plate 11 does not exist in the hollow structure 26.
For example, fig. 15 is a schematic cross-sectional structure view of the support plate in a folded state according to an embodiment of the present invention, as shown in fig. 14 and fig. 15, taking a bending form of the foldable display module as a U-shaped bending, when the foldable display module is in the folded state, the second support portion 25 located in the bendable region 13 is bent, and by providing the hollow structure 26 on the second support portion 25, the hollow structure 26 can release a bending stress of the second support portion 25 in the bending process, so as to avoid stress concentration and reduce a possibility of a crack in the second support portion 25.
The shape of the hollow structure 26 may be a rectangle as shown in fig. 14, but is not limited to this, and in other embodiments, the shape of the hollow structure 26 may also be a circle or a diamond, which is not specifically limited in this embodiment of the present invention.
With continued reference to fig. 14, optionally, the second supporting portion 25 may include a plurality of hollow structures 26, each of the hollow structures 26 has the same shape and size, and the shortest distances between any two adjacent hollow structures 26 are all equal, so that the hollow structures 26 are uniformly distributed, and thus when the second supporting portion 25 is bent, the stress is released more uniformly, which is beneficial to improving the supporting effect of the second supporting portion 25.
With reference to fig. 14, optionally, along a direction perpendicular to the bending central line K, the two hollow structures 26 adjacent to each other are staggered up and down, so as to avoid the second supporting portion 25 from being broken due to the aggregation of the hollow structures 26 as much as possible, and further avoid the hollow structures 26 from affecting the supporting effect of the supporting plate 11.
The bending center lines K are all straight lines which are located inside the second support portion 25, pass through the geometric center of the second support portion 25, and extend along a direction perpendicular to the direction in which the second support portion 25 points to the first support portion 17, and in the unfolded state, the second support portion 25 is symmetrical with respect to the bending center line K.
Fig. 16 is a schematic structural diagram of another supporting plate according to an embodiment of the present invention, and fig. 17 is a schematic structural diagram of a cross section along the direction C-C' of fig. 16, as shown in fig. 16 and fig. 17, optionally, the supporting plate 11 further includes a third supporting portion 27 located in the bendable region 13, the third supporting portion 27 is located between the first supporting portion 17 and the second supporting portion 25, and a side of the third supporting portion 27 facing away from the flexible display panel includes a groove structure 28.
For example, fig. 18 is a schematic cross-sectional structure view of another support plate according to an embodiment of the present invention in a folded state, as shown in fig. 16-18, taking a bending mode of the foldable display module as a drop-shaped bending mode, when the foldable display module is in the folded state, the second support portion 25 and the third support portion 27 located in the bendable region 13 are bent, and the third support portion 27 is adjacent to the second support portion 25 and the bending direction of the third support portion 27 is opposite to the bending direction of the second support portion 25. For the U-shaped buckle, the water drop shape buckle can reduce the occupation space of the foldable display module, thereby being beneficial to the lightness and thinness of the foldable display module.
In the present embodiment, by providing the groove structure 28 on the third support portion 27, the groove structure 28 can release the bending stress of the third support portion 27 during the bending process, thereby avoiding stress concentration and reducing the possibility of cracks in the third support portion 27.
With reference to fig. 17, taking an example that the flexible display panel (not shown) is located above the third supporting portion 27, by providing a groove structure 28 on a side of the third supporting portion 27 away from the flexible display panel, a surface of the third supporting portion 27 close to the side of the flexible display panel is a flat plane, which is helpful for improving a supporting performance of the third supporting portion 27 on the flexible display panel.
It should be noted that, in a normal situation, the bending degree of the third supporting portion 27 is smaller than the bending degree of the second supporting portion 25, and therefore, the groove structure 28 disposed on the third supporting portion 27 can meet the requirement of releasing the stress of the third supporting portion 27, so that the third supporting portion 27 does not need to be hollowed out, which is helpful to improve the supporting performance of the third supporting portion 27 on the flexible display panel.
The depth of the groove structure 28 can be set according to practical requirements, for example, the depth of the groove structure 28 is half of the thickness of the third supporting portion 27, but is not limited thereto. It will be understood that the greater the depth of the groove structure 28, the better the stress relief performance, but will affect the support performance of the third support 27 on the flexible display panel; the smaller the depth of the groove structure 28, the better the third support part 27 can support the flexible display panel, but it affects the stress release performance.
It should be noted that, for clearly illustrating the technical solutions provided by the embodiments of the present invention, the two first coils 22 are disposed on one antenna board 12 in the above embodiments, which does not limit the scope of the present invention. In practical applications, the structure, number and position of the first coil 22 on the antenna board 12 can be set according to practical requirements.
For example, fig. 19 is a schematic structural diagram of another antenna board according to an embodiment of the present invention, fig. 20 is a schematic structural diagram of another supporting board according to an embodiment of the present invention, and fig. 21 is a schematic structural diagram of a stacked structure of another supporting board and an antenna board according to an embodiment of the present invention, as shown in fig. 19 to fig. 21, the antenna coil 15 may include a plurality of first coils 22, and the plurality of first coils 22 include a plurality of first type coils 51 arranged along a first direction X and a plurality of second type coils 52 arranged along a second direction Y, where the first direction X intersects the second direction Y.
Wherein, a closed loop can be formed by connecting the leading-in terminal 221 and the leading-out terminal 222 of the first type coil 51 with the touch chip; by connecting the lead-in 221 and the lead-out 222 of the second type coil 52 with the touch chip, a closed loop can be formed. In the phase of transmitting the touch signal, the touch chip may input an ac signal to the first-type coil 51 and the second-type coil 52, where the ac signal may generate a magnetic flux in a closed loop formed by the first-type coil 51 and the touch chip, and generate a magnetic flux in a closed loop formed by the second-type coil 52 and the touch chip. Taking an object with a magnetic field as an example, when the electromagnetic pen is close to the foldable display module for touch control, the electromagnetic pen can sense the alternating current signals in the first type coil 51 and the second type coil 52, so that the alternating current signals can charge the LC oscillating circuit in the electromagnetic pen, and then the LC oscillating circuit can transmit electromagnetic feedback signals to the foldable display module.
In the touch signal receiving stage, the input of the alternating current signal to the first-type coil 51 and the second-type coil 52 may be stopped, so that both the first-type coil 51 and the second-type coil 52 may receive an electromagnetic feedback signal transmitted by an LC oscillating circuit of the electromagnetic pen, and the electromagnetic feedback signal causes a change in magnetic flux in the first-type coil 51 and the second-type coil 52, and further the first-type coil 51 and the second-type coil 52 may generate an induced current.
The first type coil 51 and the second type coil 52 are staggered horizontally and longitudinally, so that the intersection point of the first type coil 51 and the second type coil 52 with the largest induced current is the touch position.
Further, with reference to fig. 19-21, the portion of the supporting board 11 in the non-bending region 14 is a first supporting portion 17, the first supporting portion 17 has a second trace pattern 18 in the first region 141, a hollow portion 181 is disposed in the second trace pattern 18, and the second trace pattern 18 covers a vertical projection of the first trace pattern 16 along the thickness direction of the supporting board 11, so that an electromagnetic signal of an object (e.g., a magnet or an electromagnetic pen, etc.) with a magnetic field on the light-emitting surface side of the flexible display panel 10 can pass through the hollow portion 181 of the first trace pattern 16 on the supporting board 11, and the antenna coil 15 can receive the electromagnetic signal through the hollow portion 181 of the first trace pattern 16 on the supporting board 11 and convert the electromagnetic signal into an electrical signal, thereby implementing accurate interpretation of the position of the object with a magnetic field.
