Description
Touch modules, touch display modules and electronic devices Technical Field
[0001] The present application relates to the field of terminal technology, and in particular to a touch module, a touch display module, and an electronic device. Background Art
[0002] Wireless Charging Technology (WCT) can use conductive media such as electric fields, magnetic fields, microwaves or lasers to achieve wireless transmission of electrical energy. Due to its advantages such as no wire restrictions and no plugging and unplugging, it is increasingly used in electronic devices. At present, more and more electronic devices (such as mobile phones, tablets, etc.) have wireless power supply functions. During the wireless power supply process, the wireless power supply receiving coil in the electronic device can generate an alternating magnetic field with the wireless power supply device outside the electronic device. When the touch panel of the electronic device is located in the alternating magnetic field, the alternating magnetic field will affect the touch sensing signal transmitted by the touch sensing electrode of the touch panel, thereby affecting the touch function of the touch panel.
[0003] Summary of the Invention
[0004] Embodiments of the present application provide a touch module, a touch display module, and an electronic device. A first touch area and a second touch area are arranged side by side along a first direction within a touch panel. First touch sensing electrodes within the first touch area are insulated from second touch sensing electrodes within the second touch area, effectively preventing touch sensing signals transmitted by the first touch sensing electrodes from being interfered with by an alternating magnetic field.
[0005] A first aspect of an embodiment of the present application provides a touch module, including a touch panel and a touch circuit;
[0006] The touch panel includes a first touch area and a second touch area arranged in parallel along a first direction;
[0007] The first touch area includes n first touch sensing electrodes extending along a first direction and arranged in parallel along a second direction, and m1 touch driving electrodes extending along a second direction and arranged in parallel along the first direction, where the second direction is different from the first direction;
[0008] The second touch area includes q second touch sensing electrodes extending along the first direction and arranged in parallel along the second direction, and m2 touch driving electrodes extending along the second direction and arranged in parallel along the first direction, where n, m1, q, and m2 are positive integers;
[0009] The first touch sensing electrode and the second touch sensing electrode are insulated from each other;
[0010] The touch circuit is connected to n first touch sensing electrodes, q second touch sensing electrodes, and m touch driving electrodes, where m=m1+m2.
[0011] When the second touch area is covered by the alternating magnetic field, the alternating magnetic field can be prevented from being transmitted to the first touch sensing electrode in the first touch area through the second touch sensing electrode in the second touch area. That is, during the touch recognition process of the first touch area, the capacitance value of the capacitor in the first touch area can be effectively prevented from being interfered with by the alternating magnetic field, thereby preventing the touch sensing signal transmitted by the first touch sensing electrode from being interfered with by the alternating magnetic field. As a result, whether a touch operation is received in the first touch area and the location of the touch operation can be accurately sensed.
[0012] In a possible implementation, n is the same as q, the n first touch sensing electrodes are arranged in sequence from the 1st to the nth, and the q second touch sensing electrodes are arranged in sequence from the 1st to the qth, wherein the first touch sensing electrodes and the second touch sensing electrodes located in the same position sequence are located in the same straight line and are insulated from each other.
[0013] In a possible implementation, n is greater than q, the n first touch sensing electrodes are arranged in sequence from the 1st to the nth, and the q second touch sensing electrodes are arranged in sequence from the 1st to the qth, and the first touch sensing electrodes and the second touch sensing electrodes that are i rows apart are located in the same straight line and insulated from each other, where 0≤i≤nq.
[0014] In this embodiment, the number of touch sensing electrodes (the sum of the number of first touch sensing electrodes RXA and second touch sensing electrodes RXB) is smaller, the number of sensing channels actually used by the touch circuit is smaller, and the capability requirement for the touch circuit is lower. That is, even under the control of a touch circuit with lower capability, it is still possible to sense whether a touch operation is received in the first touch area AA1 and the position of the touch operation.
[0015] In a possible implementation, part of the m1 touch driving electrodes overlaps with the m2 touch driving electrodes.
[0016] In a possible implementation, the touch module includes a flexible folding area, and the first touch area and the second touch area are respectively located on opposite sides of the folding area; the first touch sensing electrode and the second touch sensing electrode are insulated from each other in the folding area.
[0017] In a possible implementation, when the touch module is unfolded along the folding area to enter the unfolded state, the first touch area and the second touch area are located in the same plane.
[0018] In a possible implementation, when the touch module is folded along the folding area to enter the folded state, the first touch area and the second touch area are located in different planes.
[0019] In one possible embodiment, the touch control circuit includes a touch panel chip. The touch panel chip is configured to receive touch sensing signals within a first touch sensing area from n first touch sensing electrodes when outputting touch drive signals to m1 touch drive electrodes, and to receive touch sensing signals within a second touch sensing area from q second touch sensing electrodes when outputting touch drive signals to m2 touch drive electrodes, thereby sensing touch operations. In this embodiment, using a single touch panel chip to sense touch operations is simpler and more convenient, saving data processing resources.
[0020] A second aspect of the embodiments of the present application provides a touch display module, which includes the touch module of the above embodiment and a display panel, and the display panel is used to display images.
[0021] In one possible embodiment, the touch display module includes a bending area and two non-bending areas, the two non-bending areas are located on opposite sides of the bending area, the two non-bending areas are respectively arranged corresponding to the first touch area and the second touch area, and the bending area is arranged corresponding to the folding area. When the touch module is unfolded along the folding area to enter the unfolded state, the touch display module is unfolded along the bending area to enter the unfolded state, and the two non-bending areas are located in the same plane.
[0022] In one possible embodiment, the touch display module includes a bending area and two non-bending areas, the two non-bending areas are located on opposite sides of the bending area, the two non-bending areas are respectively arranged corresponding to the first touch area and the second touch area, and the bending area is arranged corresponding to the folding area. When the touch module is folded along the folding area into a folded state, the touch display module is folded along the bending area into a folded state, and the two non-bending areas are located in different planes.
[0023] A third aspect of an embodiment of the present application provides an electronic device, which includes the touch module and the wireless power receiving coil described in the aforementioned embodiment.

[0050] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.
[0051] The electronic device in the embodiments of the present application may be referred to as user equipment (UE) or terminal, etc. For example, the electronic device may be a tablet computer (portable Android device, PAD), a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device, an in-vehicle device, a wireless terminal in industrial control, a wireless terminal in remote medical, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, and other mobile terminals or fixed terminals. The embodiments of the present application do not specifically limit the form of the electronic device.
[0052] In an embodiment of the present application, FIG1 schematically shows the structure of an electronic device 10. Referring to FIG1 , the electronic device 10 is taken as an electronic device with a wireless communication function as an example for explanation. The electronic device with a wireless communication function may be, for example, a folding screen device. The folding screen device may be a foldable mobile phone. The folding screen device includes a flexible folding screen, in other words, the folding screen of the electronic device has a bendable property. For the convenience of description, the embodiment of the present application may define the width direction of the electronic device 10 as the first direction X, the length direction of the electronic device 10 as the second direction Y, and the thickness direction of the electronic device 10 as the third direction Z, wherein the first direction X, the second direction Y and the third direction Z are perpendicular to each other to form a three-dimensional coordinate system.
[0053] Figure 2 schematically shows the structure of the electronic device 10 in a semi-folded state. Figure 3 schematically shows the structure of the electronic device 10 in a folded state. Referring to Figures 2 and 3, the embodiment of the present application is described by taking the electronic device 10 with an external folding design as an example. The electronic device 10 includes a touch display module 20. For the electronic device 10 with an external folding design, when the electronic device 10 is in a folded state, the touch display module 20 is located on the outside, and the touch display module 20 is in a visible state. It should be noted that the touch display module 20 described in Figures 2 and 3 may be part or all of the folding screen described in Figure 1.
[0054] The electronic device 10 includes a housing 30. The housing 30 is used to support the touch display module 20. The touch display module 20 is bendable and can be folded when subjected to an external force. When the electronic device 10 is in the unfolded state, the touch display module 20 unfolds to facilitate touch display.
[0055] The housing 30 includes a frame 31 and a hinge 32. The frame 31 is rotatably connected to the hinge 32. When a rotational torque is applied to the frame 31, the frame 31 can rotate and fold relative to the hinge 32. In the embodiment of the present application, an electronic device 10 including two frames 31 is used as an example for description. One frame 31 can serve as a main support body, and the other can serve as a secondary support body. The two frames 31 rotate relative to the hinge 32 respectively to switch between a folded state and an unfolded state. When the two frames 31 are stacked on each other, the electronic device 10 is in a folded state. When the two frames 31 move away from each other from the folded state and unfold to a plane, the electronic device 10 is in an unfolded state. The process of the frame 31 from the folded state to the unfolded state is an unfolding process, and the process from the unfolded state to the folded state is a folding process.
[0056] The touch display module 20 may include a non-bending area 21 and a bending area 22. The non-bending area 21 is arranged corresponding to the frame 31. The bending area 22 is arranged corresponding to the hinge 32. The two non-bending areas 21 are respectively connected to the two frames 31. The two non-bending areas 21 are respectively located on opposite sides of the bending area 22, that is, the bending area 22 may be located between the two non-bending areas 21. Optionally, the non-bending area 21 being arranged corresponding to the frame 31 may mean that the position of the non-bending area 21 changes as the position of the frame 31 changes, and the projections of the non-bending area 21 and the frame 31 in the third direction Z overlap. The bending area 22 being arranged corresponding to the hinge 32 may mean that the position of the bending area 22 changes as the position of the hinge 32 changes, and the projections of the bending area 22 and the hinge 32 in the third direction Z overlap.
[0057] When the two frames 31 are in a folded state, the touch display module 20 is in a folded state. When the two frames 31 are in a folded state, the two frames 31 are located between the two non-bending areas 21. The touch display module 20 is located on the outside of the frames 31, so that the touch display module 20 can be observed when observed from the outside. The bending area 22 of the touch display module 20 can be bent into an arc shape. When the two frames 31 are in an unfolded state, the touch display module 20 is unfolded, that is, the non-bending area 21 and the bending area 22 of the touch display module 20 are in an unfolded state. The electronic device 10 can change its overall size by folding or unfolding, and at the same time, it can also have a relatively large touch area in the unfolded state.
[0058] For example, FIG4 shows a partial decomposition structure of the electronic device 10. Referring to FIG4 , the electronic device 10 of the embodiment of the present application further includes a wireless power receiving coil 40 and a battery 50. The housing 30 may further include a battery cover 33. The wireless power receiving coil 40 is located between the touch display module 20 and the frame 31. The battery 50 is located between the frame 31 and the battery cover 33. The material of the battery cover 33 may be an insulating material, such as plastic or glass. The electronic device 10 can be folded outward along the hinge 32 (or, the touch display module 20 can be folded outward along the bending zone 22), as shown in FIG5 , which is a schematic diagram of the cross-sectional structure of the electronic device 10 when it is in a folded state. As shown in FIG5 , when the electronic device 10 is folded outward along the hinge 32 (that is, when the touch display module 20 is folded outward along the bending zone 22), the electronic device 10 can be wrapped by the touch display module 20.
[0059] For example, FIG6 schematically shows a partial cross-sectional structural diagram of the touch display module 20. Referring to FIG6 , the touch display module 20 may include a touch panel 201 and a display panel 202. The touch panel 201 may be used to sense touch operations and identify the location of the touch operations. In one example, taking the touch panel 201 as a capacitive touch panel as an example, as shown in FIG6 , the touch panel 201 may include a touch drive layer 2011, an insulating isolation layer 2012 and a touch sensing layer 2013. The touch drive layer 2011 is used to provide touch drive electrodes, and the touch sensing layer 2013 is used to provide touch sensing electrodes. The touch drive electrodes and touch sensing electrodes insulated from each other by the insulating isolation layer 2012 may respectively constitute the two poles of the capacitor. The touch drive electrodes are used to load touch drive signals. Driven by the touch drive signals, the capacitor outputs touch sensing signals from the touch sensing electrodes to sense and identify whether the touch panel 201 receives a touch operation and the location of the touch operation. The display panel 202 is used to display images, videos, etc. In one example, taking the display panel 202 as an OLED display panel, as shown in FIG6 , the display panel 202 may include a substrate 2021, a thin-film transistor layer 2022, a first electrode layer 2023, a light-emitting structure layer 2024, a second electrode layer 2025, and an encapsulation layer 2026. The substrate 2021 may be made of glass or plastic. The thin-film transistor layer 2022 includes a source electrode and a drain electrode. The first electrode layer 2023 may be electrically connected to the drain electrode. A second electrode layer 2025 is disposed above the light-emitting structure layer 2024. The first electrode layer 2023 may serve as an anode, while the second electrode layer 2025 may serve as a cathode. The encapsulation layer 2026 may prevent moisture or oxygen from entering the display area of the display panel 202. It should be noted that the touch display module 20 shown in FIG6 is merely an example. In other embodiments, the touch display module 20 may include other types. For example, the display panel 202 shown in FIG6 may be replaced with an LCD display panel. For another example, the touch display module 20 may also include a cover glass 203 (not shown) and a substrate 204 (not shown). The cover glass 203 is located at the outermost layer of the touch display module 20 (i.e., the surface of the cover glass 203 can be in contact with the outside air). The cover glass 203 can be made of reinforced glass or a thin film material to effectively prevent the touch display module 20 from being scratched, worn, or broken. The substrate 204 can be located at the innermost layer of the touch display module 20 and can be formed of at least one of laminated glass, colored glass, ceramic, polymer, or metal (e.g., aluminum, stainless steel, or magnesium). For another example, the touch display module 20 may also include other circuit components required for touch display, such as a touch circuit 205 (not shown), which is not limited thereto.
[0060] In the embodiment of the present application, touch panel 201 includes but is not limited to any one of capacitive touch panel, resistive touch panel, infrared touch panel or surface acoustic wave touch panel.The capacitive touch panel can work by any object (for example, human skin) holding an electric charge, and the capacitive touch screen can be a self-capacitive touch screen, can also be a mutual capacitance touch screen, can also be a touch screen combining self-capacitance and mutual capacitance.The resistive touch panel can work based on pressure sensing, and when pressed on the outer layer by a fingertip or other object, the surface film can be concavely deformed, and two layers of inner layers can touch and conduct electricity, so that the position of touch operation can be detected based on the conductive position.The infrared touch panel can work based on an infrared matrix, and when the horizontal and vertical infrared rays in the infrared matrix are blocked by a fingertip or other object, the position of touch operation can be detected based on the position of the blocked infrared rays. A surface acoustic wave touch panel operates based on signal attenuation. When a finger touches the surface acoustic wave touch panel, the finger absorbs a portion of the acoustic wave energy, and the signal received by the controller attenuates. This allows the location of the touch operation to be detected based on the location of the attenuated signal.
[0061] The following takes the mutual capacitance touch screen as an example to explain the mutual capacitance touch panel in detail.
[0062] For example, FIG7 shows a partial exploded structure of a touch panel 201. Referring to FIG7 , the touch panel 201 according to an embodiment of the present application includes a touch drive layer 2011, an insulating isolation layer 2012, and a touch sensing layer 2013. The touch drive layer 2011 may include w touch drive electrodes TX (represented as TX1, TX2, TX3, TX4, TX5, TX6, TX7, ..., TXw) extending along a second direction Y and arranged in parallel along a first direction X. The touch sensing layer 2013 may include v touch sensing electrodes RX (represented as RX1, RX2, RX3, RX4, RX5, RX6, RX7, RX8, RX9, ..., RXv) extending along the first direction X and arranged in parallel along a second direction Y. In this embodiment of the present application, the touch drive electrodes TX in the touch drive layer 2011 may extend along the second direction Y via a patterned conductive layer, and the touch sensing electrodes RX in the touch sensing layer 2013 may also extend along the first direction X via a patterned conductive layer. The embodiment of the present application does not limit the shape of the pattern. For example, the touch drive electrodes TX and the touch sensing electrodes RX can extend in the diamond pattern shown in the figure. It should be noted that the embodiment of the present application does not limit the shape and material of the conductive layer. For example, the conductive layer can be formed of at least one of ITO, stainless steel, or magnesium. It should be noted that in other embodiments, the touch drive electrodes TX and the touch sensing electrodes RX can also extend in other forms without limitation. It should be noted that the projection of the partial decomposition structure shown in Figure 7 in the third direction Z can be exemplified by referring to Figure 8.
[0063] In one implementation of the present application, the touch drive electrodes TX and the touch sensing electrodes RX can form a capacitor at their intersection. Specifically, when the touch drive layer 2011 and the touch sensing layer 2013 are brought into proximity in the third direction Z, the touch drive electrodes TX and the touch sensing electrodes RX can form the two poles of a capacitor at their intersection. The touch drive electrodes TX are used to apply touch drive signals, and when driven by the touch drive signals, the capacitors output touch sensing signals corresponding to the touch sensing electrodes RX, thereby sensing and identifying whether the touch panel has received a touch operation and the location of the touch operation.
[0064] To better illustrate the embodiments, the following uses w=9 and v=11 as an example, and FIG9 is used to illustrate the touch panel 201 shown in FIG7 . As shown in FIG9 , when the nine touch drive electrodes TX are represented as TX1, TX2, TX3, TX4, TX5, TX6, TX7, TX8, and TX9, and the eleven touch sensing electrodes RX are represented as RX1, RX2, RX3, RX4, RX5, RX6, RX7, RX8, RX9, RX10, and RX11, the nine touch drive electrodes TX can be arranged in the order of TX1 to TX9, and the eleven touch sensing electrodes RX can be arranged in the order of RX1 to RX11. It should be noted that the embodiments of the present application are described using w=9 and v=11 as an example. In other embodiments, the value of w can be other values (such as 32), and the value of v can be other values (such as 37), without limitation.
[0065] In one implementation of the present application, the touch drive electrodes TX and the touch sensing electrodes RX may form a capacitor at their intersection (as shown by the black dots in FIG9 ). Alternatively, the touch drive electrodes TX and the touch sensing electrodes RX may form the two poles of a capacitor at their intersection. The touch drive electrodes TX are used to apply touch drive signals, and when driven by the touch drive signals, the capacitors output touch sensing signals corresponding to the touch sensing electrodes RX to sense and identify whether the touch panel has received a touch operation and the location of the touch operation.
[0066] Specifically, the touch drive electrode TX is sequentially loaded with a touch drive signal, and the capacitance of the touch drive electrode TX and the touch sensing electrode RX at the intersection position is charged, and the touch sensing signal is output through the corresponding touch sensing electrode RX. When a finger or other conductive object touches the touch panel 201, the capacitance value of the area corresponding to the touch point is changed. When the capacitance value changes, the corresponding touch sensing signal changes accordingly. At the same time, the change in the touch sensing signal can be identified to identify the coordinate position of the touch point. It should be noted that when the value of w is large and the value of v is also large, the more capacitance the touch drive electrode TX and the touch sensing electrode RX have at each intersection position within a unit area, the more effectively the touch position recognition accuracy can be improved. It should be noted that the specific implementation of touch recognition can be found in relevant materials and will not be elaborated on.
[0067] Please refer to Figure 10, which shows a touch control schematic diagram of a portion of the touch area of the touch panel 201. As shown in Figure 10, taking the touch area as an example, which includes 9 touch drive electrodes and 11 touch sensing electrodes, with the rectangles representing the capacitors formed at the intersection of the touch drive electrodes TX and the touch sensing electrodes RX, and the numbers within the rectangles representing the capacitance values of the capacitors, the 9 touch drive electrodes and 11 touch sensing electrodes can each form 99 capacitors, and the initial capacitance values of the 99 capacitors are shown in (a) of Figure 10. When a finger or other conductive object touches the touch panel 201, as can be seen from the comparison between (a) and (b) in Figure 10, the capacitance values at the intersection positions of TX1 and RX4, TX2 and RX4, TX3 and RX4, TX4 and RX4, TX5 and RX4, TX1 and RX5, TX2 and RX5, TX3 and RX5, TX4 and RX5, TX5 and RX5, TX1 and RX6, TX2 and RX6, TX3 and RX6, TX4 and RX6, TX5 and RX6, TX1 and RX7, TX2 and RX7, TX3 and R7, TX4 and RX6, and TX5 and RX7 change, and the output touch sensing signal changes accordingly. Based on the change in the touch sensing signal, it can be identified that the touch operation is at the intersection position of TX3 and RX6.
[0068] When the electronic device 10 with an external folding design is in a folded state for wireless charging, since the electronic device 10 is wrapped by the touch display module 20, when wireless charging is performed between the wireless power receiving coil 40 and the wireless power supply device 300, the magnetic induction line must penetrate the touch display module 20 (or, the magnetic induction line must penetrate the touch panel 201 in the touch display module 20). For example, Figures 11 and 12 show schematic diagrams of charging the electronic device 10 in a folded state. As shown in Figures 11 and 12, the wireless power receiving coil 40 in the electronic device 10 and the wireless power transmitting coil 3001 in the wireless power supply device 300 can form a coupling structure, and there is mutual inductance between the wireless power receiving coil 40 and the wireless power transmitting coil 3001, and wireless charging is achieved through electromagnetic induction. During wireless charging, the touch panel 201 in the touch display module 20 is located between the wireless power receiving coil 40 and the external wireless power transmitting coil 3001. The alternating magnetic field can pass through the touch panel 201 to reach the wireless power receiving coil 40. The fundamental frequency and / or harmonics of the alternating magnetic field will affect the touch sensing signal transmitted by the touch sensing electrode RX of the touch panel 201, thereby affecting the touch function of the touch panel 201.
[0069] For example, following the example of FIG10 , taking the case where RX5 to RX8 extending along the first direction X are covered by the alternating magnetic field as an example, the initial capacitance values of 99 capacitors are shown in FIG13 (a). Compared with the initial capacitance values shown in FIG10 (a), the fundamental frequency and / or harmonics of the alternating magnetic field may cause the initial capacitance values of the capacitors related to RX5, RX6, RX7, and RX8 to increase by an order of magnitude (10 1 ). When a finger or other conductive object touches the touch panel 201, as can be seen from the comparison between FIG13(a) and FIG13(b), the capacitance change caused by the touch operation is small relative to the initial capacitance value, and the change in the output touch sensing signal is small, and the location of the touch operation cannot be accurately identified.
[0070] Based on this, an embodiment of the present application provides an improved solution. In this improved solution, a first touch area AA1 and a second touch area AA2 can be arranged side by side along the first direction X in the touch panel 201, and the first touch sensing electrodes RXA of the first touch area AA1 and the second touch sensing electrodes RXB of the second touch area AA2 are insulated from each other.
[0071] Optionally, the touch panel 201 may include a flexible folding region, i.e., the touch panel 201 includes a folding region with bendability, and the first touch region and the second touch region may be located on opposite sides of the folding region; the first touch sensing electrode and the second touch sensing electrode are insulated from each other in the folding region. It should be noted that the folding region may be arranged to correspond to the bend region 22 described in the aforementioned embodiment. For example, the position of the folding region changes with the position of the bend region 22, and the projection of the folding region and the projection of the bend region 22 in the third direction Z overlap. Optionally, the size of the folding region in the first direction X may be smaller than or equal to the bend region 22, without limitation.
[0072] In an optional embodiment, please refer to FIG14 , which shows a schematic diagram of the first touch area AA1 and the second touch area AA2 of the touch panel 201 arranged side by side along the first direction X. It should be noted that, for the sake of convenience of explanation, in the drawings of this application, geometric figures filled with oblique lines may be used to represent the first touch area AA1 set in the touch panel 201, and geometric figures filled with diamonds may be used to represent the second touch area AA2 set in the touch panel 201. As shown in FIG14 , the first touch area AA1 is arranged side by side with the second touch area AA2 in the horizontal direction, and the size of the first touch area AA1 along the second direction Y and the size of the second touch area AA2 along the second direction Y may be equal, that is, the first touch area AA1 and the second touch area AA2 are completely separated along the folding area, and the size of the folding area in the second direction Y is equal to that of the touch panel 201.
[0073] For example, corresponding to the segmentation method shown in FIG14 , FIG15A illustrates a schematic layout diagram of touch drive electrodes and touch sensing electrodes provided in an embodiment of the present application. As shown in FIG15A , the first touch area AA1 includes 11 first touch sensing electrodes RXA extending along the first direction X and arranged in parallel along the second direction Y, and 4 touch drive electrodes TX extending along the second direction Y and arranged in parallel along the first direction X. The second touch area AA2 includes 11 second touch sensing electrodes RXB extending along the first direction X and arranged in parallel along the second direction Y, and 5 touch drive electrodes TX extending along the second direction Y and arranged in parallel along the first direction X.
[0074] The number of first touch sensing electrodes RXA and second touch sensing electrodes RXB in the touch panel 201 is the same. That is, the touch panel 201 includes n first touch sensing electrodes RXA and q second touch sensing electrodes RXB, where n is the same as q. The n first touch sensing electrodes RXA are arranged in order from 1st to nth, and the q second touch sensing electrodes RXB are arranged in order from 1st to qth. Furthermore, the first touch sensing electrodes RXA and the second touch sensing electrodes RXB located in the same position and sequence are substantially aligned and insulated from each other (subsequent embodiments will use insulation in the folding region as an example).
[0075] As shown in FIG15A , the 11 first touch sensing electrodes RXA of the first touch area AA1 can be represented as RXA1, RXA2, RXA3, RXA4, RXA5, RXA6, RXA7, RXA8, RXA9, RXA10, and RXA11, respectively. The 11 first touch sensing electrodes RXA can be arranged in the order RXA1 to RXA11. The 11 second touch sensing electrodes RXB of the second touch area AA2 can be represented as RXB1, RXB2, RXB3, RXB4, RXB5, RXB6, RXB7, RXB8, RXB9, RXB10, and RXB11, respectively. The 11 second touch sensing electrodes RXB can also be arranged in the order RXB1 to RXB11. The first touch sensing electrode RXA1 and the second touch sensing electrode RXB1 located in the first row (first position) are located substantially in the same straight line and are insulated from each other in the folding area. The first touch sensing electrode RXA2 and the second touch sensing electrode RXB2 located in the second row (second position) are located substantially in the same straight line and are insulated from each other in the folding area. Similarly, the first touch sensing electrode RXA11 and the second touch sensing electrode RXB11 located in the eleventh row (eleventh position) are located substantially in the same straight line and are insulated from each other in the folding area.
[0076] FIG15A illustrates an example in which the number m1 of touch drive electrodes TX in the first touch area AA1 is 4, and the number m1 of touch drive electrodes TX in the second touch area AA2 is 5. The four touch drive electrodes TX and the 11 first touch sensing electrodes RXA in the first touch area AA1 can form a capacitor at the intersection of the first touch area AA1 (for example, the black dots shown in FIG15A ). The four touch drive electrodes TX are used to apply touch drive signals. Under the touch drive signals, the capacitors output touch sensing signals corresponding to the 11 first touch sensing electrodes RXA to sense whether a touch operation is received in the first touch area AA1 and the location of the touch operation. The five touch drive electrodes TX and the eleven second touch sensing electrodes RXB of the second touch area AA2 can form a capacitor at the intersection of the second touch area AA2 (for example, the white dots shown in FIG15A ). The five touch drive electrodes TX are used to apply touch drive signals. Under the touch drive signals, the capacitor outputs touch sensing signals corresponding to the eleven second touch sensing electrodes RXB to sense whether a touch operation is received in the second touch area AA2 and the location of the touch operation.
[0077] Optionally, the m1 touch drive electrodes TX are part of the multiple touch drive electrodes, and the m2 touch drive electrodes TX are another part of the multiple touch drive electrodes. In this embodiment of the present application, m1+m2=w must be satisfied. The specific values of m1 and m2 can be set based on the position of the folding area, and their specific positions are not limited to the exemplary description of this embodiment. For example, when the folding area is located at the position shown in Figure 15B, the value of m1 can be reduced from 4 to 3, and the value of m2 can be increased from 5 to 6. In other words, the second touch area in this embodiment of the present application is set corresponding to the position of the wireless power receiving coil 40 in the electronic device 10, and the size of the second touch area in the first direction X changes with the change of the position of the wireless power receiving coil 40, so that the projection of the second touch area in the third direction Z includes the projection of the wireless power receiving coil 40 in the third direction Z.
[0078] Please refer to Figure 16, which shows a touch control schematic diagram of a portion of the touch control area of the touch panel 201. When the touch panel 201 is configured according to the embodiment shown in Figure 15A, the first touch sensing electrode RXA in the first touch control area AA1 and the second touch sensing electrode RXB in the second touch control area AA2 are isolated and insulated from each other. Compared with the touch control schematic shown in Figure 13, it can be seen that the improved solution shown in Figure 15A can prevent the alternating magnetic field from being transmitted through the second touch sensing electrode RXB in the second touch control area AA2 to the first touch sensing electrode RXA in the first touch control area AA1 when the second touch control area AA2 is covered by the alternating magnetic field. In other words, it can effectively prevent the capacitance value of the capacitor in the first touch control area AA1 from being disturbed by the alternating magnetic field during the touch recognition process of the first touch control area AA1, thereby preventing the touch sensing signal transmitted by the first touch sensing electrode RXA from being disturbed by the alternating magnetic field. Specifically, compared to the touch schematic diagram shown in (a) of FIG13 , in the touch schematic diagram shown in (a) of FIG16 , the initial capacitance values of the capacitors related to RXB5, RXB6, RXB7, and RXB8 in the second touch area AA1 are increased by one order of magnitude (10 1 ), the initial capacitance values of the capacitors associated with RXA5, RXA6, RXA7, and RXA8 in the first touch area AA1 are substantially equal to the initial capacitance values shown in (a) of FIG10 . When a finger or other conductive object touches the touch panel 201, as can be seen from the comparison between (a) and (b) of FIG16 , the capacitance value in the first touch area AA1 changes, and the output touch sensing signal changes accordingly. Based on the change in the touch sensing signal, the location of the touch operation in the first touch area AA1 can be identified. In other words, during the touch operation recognition process in the first touch area AA1, the touch sensing signal transmitted from the first touch sensing electrode RXA is not interfered with by the alternating magnetic field of the wireless power receiving coil in the working state in the second touch area AA2. The touch sensing signal is relatively accurate, and thus it is possible to accurately sense whether a touch operation is received in the first touch area AA1 and the location of the touch operation.
[0079] More specifically, when the touch panel 201 is in the unfolded state, the first touch area AA1 and the second touch area AA2 are located in the same plane. When the touch panel 201 is in the folded state, the touch panel 201 is located in different planes. The first touch area AA1 of the touch panel 201 faces the user and can be used to receive touch operations. Simultaneously, the display area of the display panel 202 corresponding to the first touch area AA1 also faces the user and can be used to display images. The second touch area AA2 faces away from the user and is adjacent to the wireless power supply device 300 outside the electronic device 10. It should be noted that, in one scenario, the portion of the touch panel 201 corresponding to the first touch area AA1 can be called the first screen, and the portion corresponding to the second touch area AA2 can be called the second screen (or, the portion of the touch panel 201 corresponding to the first touch area AA1 is called the second screen, and the portion corresponding to the second touch area AA2 is called the first screen); in another scenario, the portion of the touch panel 201 corresponding to the first touch area AA1 can be called the main screen, and the portion corresponding to the second touch area AA2 can be called the secondary screen (or, the portion of the touch panel 201 corresponding to the first touch area AA1 is called the secondary screen, and the portion corresponding to the second touch area AA2 is called the main screen); there is no limitation.
[0080] When the touch panel 201 configured in the embodiment shown in FIG15A is in a folded state, when the second touch area AA2 is covered by the alternating magnetic field, the touch sensing signal transmitted by the touch sensing electrode in the first touch area AA1 can be prevented from being interfered with, thereby accurately sensing whether a touch operation is received in the first touch area AA1 and the position of the touch operation.
[0081] It should be noted that the touch display module 20 includes two non-bending areas 21 and a bending area 22. The two non-bending areas 21 are respectively located on opposite sides of the bending area 22, that is, the bending area 22 is located between the two non-bending areas 21. The two non-bending areas 21 are respectively set corresponding to the first touch area AA1 and the second touch area AA2. For example, the position of the non-bending area 21 changes with the position of the first touch area AA1 and the second touch area AA2, and one non-bending area 21 overlaps with the projection of the first touch area AA1 in the third direction Z, and the other non-bending area 21 overlaps with the projection of the second touch area AA2 in the third direction Z. The bending area 22 is set corresponding to the folding area. For example, the position of the bending area 22 changes with the position of the folding area, and the bending area 22 overlaps with the projection of the folding area in the third direction Z.
[0082] When the touch panel 201 is unfolded along the folding region into the unfolded state, the touch display module 20 is unfolded along the bending region 22 into the unfolded state, and the two non-bending regions 21 are located in the same plane. When the touch panel 201 is folded along the folding region into the folded state, the touch display module 20 is folded along the bending region 22 into the folded state, and the two non-bending regions 21 are located in different planes.
[0083] It should be noted that the housing 30 of the electronic device 10 includes a hinge 32 and two frames 31, each of which is rotatably connected to the hinge 32. The two frames 31 are respectively provided corresponding to the first touch area AA1 and the second touch area AA2. For example, the position of the frame 21 changes as the positions of the first touch area AA1 and the second touch area AA2 change, and one frame 31 overlaps with the projection of the first touch area AA1 in the third direction Z, and the other frame 31 overlaps with the projection of the second touch area AA2 in the third direction Z. The hinge 32 is provided corresponding to the folding area. For example, the position of the hinge 32 changes as the position of the folding area changes, and the hinge 32 overlaps with the projection of the folding area in the third direction Z.
[0084] When the touch panel 201 is unfolded along the folding area into the unfolded state, the electronic device is unfolded along the hinge 32 into the unfolded state, and the two frames 31 are located in the same plane. When the touch panel 201 is folded along the folding area into the folded state, the electronic device is folded along the hinge 32 into the folded state, and the two frames 31 are located in different planes.
[0085] Furthermore, the touch panel 201 also corresponds to a touch circuit 205. The touch circuit 205 is connected to the w touch drive electrodes TX and the v touch sensing electrodes RX. The touch circuit 205 is used to output touch drive signals and load them to the touch drive electrodes TX. At the same time, it receives touch sensing signals from the touch sensing electrodes RX and identifies whether the touch panel 201 has received a touch operation and the location of the touch operation based on the touch sensing signals. It should be noted that the touch circuit 205 mentioned in the embodiments of the present application can be any circuit unit with data processing capabilities. For example, the touch circuit 205 can be a touch panel chip (Touch Panel IC, TPIC).
[0086] In an optional embodiment, the touch circuit 205 may be connected to m touch driving electrodes TX, n first touch sensing electrodes RXA, and q second touch sensing electrodes RXB, respectively, where m=m1+m2, m1 is the number of touch driving electrodes TX in the first touch area AA1, and m2 is the number of touch driving electrodes TX in the second touch area AA2.
[0087] For example, as shown in FIG17 , the nine drive channels of the touch circuit 205 are respectively connected to one end of the nine touch drive electrodes TX, and the 22 sensing channels are respectively connected to one end of the 11 first touch sensing electrodes RXA and one end of the 11 second touch sensing electrodes RXB. That is, one drive channel of the touch circuit 205 is connected to one end of one touch drive electrode TX, and one sensing channel is connected to one end of one touch sensing electrode RX (including the first touch sensing electrode RXA or the second touch sensing electrode RXB). In one implementation, when the touch circuit 205 sequentially outputs touch drive signals to four touch drive electrodes TX, namely, TX1 to TX4, the touch circuit 205 can receive touch sensing signals from the 11 first touch sensing electrodes RXA. Furthermore, when the touch circuit 205 sequentially outputs touch drive signals to five touch drive electrodes TX, namely, TX5 to TX9, the touch circuit 205 can receive touch sensing signals from the 11 second touch sensing electrodes RXB.
[0088] It should be noted that the number of drive channels supported by the touch circuit 205 of the embodiment of the present application may be greater than or equal to the number of drive channels actually used by the touch circuit 205. Similarly, the number of sensing channels supported by the touch circuit 205 of the embodiment of the present application may be greater than or equal to the number of sensing channels actually used by the touch circuit 205. Optionally, some channels of the touch circuit 205 can be used as drive channels or sensing channels, and their use can be adaptively allocated based on demand without limitation.
[0089] To reduce the number of sensing channels actually used by the touch circuit 205, the first touch area AA1 of the present embodiment can be larger than the second touch area AA2 along the second direction Y. Specifically, the first touch area AA1 and the second touch area AA2 are separated along a folding region parallel to the second direction Y, where the folding region is smaller than the size of the touch panel 201 along the second direction Y. Please refer to FIG18 , which shows another schematic diagram of the first touch area AA1 and the second touch area AA2 arranged side by side along the first direction X of the touch panel 201. As shown in FIG18 , the second touch area AA2 can optionally be located above the first touch area AA1, as shown in FIG18 (a); alternatively, the second touch area AA2 can also be located below the first touch area AA1, as shown in FIG18 (b). Alternatively, the second touch area AA2 can also be located in the middle of the first touch area AA1, as shown in FIG18 (c). It should be noted that the second touch area AA2 can be set at a position corresponding to the wireless power receiving coil 40 , and its specific position is not limited to the position shown in the drawings of this embodiment.
[0090] For example, using the segmentation method shown in (c) of Figure 18 as an example, Figure 19A illustrates another exemplary layout of touch drive electrodes and touch sensing electrodes. As shown in Figure 19A, the first touch area AA1 includes eleven first touch sensing electrodes RXA extending along the first direction X and arranged in parallel along the second direction Y, and nine touch drive electrodes TX extending along the second direction Y and arranged in parallel along the first direction X. The second touch area AA2 includes four second touch sensing electrodes RXB extending along the first direction X and arranged in parallel along the second direction Y, and five touch drive electrodes TX extending along the second direction Y and arranged in parallel along the first direction X.
[0091] The number of first touch sensing electrodes RXA in the touch panel 201 is greater than the number of second touch sensing electrodes RXB. That is, the touch panel 201 includes n first touch sensing electrodes RXA and q second touch sensing electrodes RXB, where n is greater than q. The n first touch sensing electrodes RXA are arranged in order from 1st to nth, and the q second touch sensing electrodes RXB are arranged in order from 1st to qth. Furthermore, i rows of first touch sensing electrodes RXA and second touch sensing electrodes RXB are substantially aligned and insulated from each other in the folding region, with 0≤i≤nq.
[0092] As shown in FIG19A , the eleven first touch sensing electrodes RXA of the first touch area AA1 can be represented as RXA1, RXA2, RXA3, RXA4, RXA5, RXA6, RXA7, RXA8, RXA9, RXA10, and RXA11, respectively. The eleven first touch sensing electrodes RXA can be arranged sequentially from RXA1 to RXA11. The four second touch sensing electrodes RXB of the second touch area AA2 can be represented as RXB1, RXB2, RXB3, and RXB4, respectively. The four second touch sensing electrodes RXB can also be arranged sequentially from RXB1 to RXB4. For example, taking i=4, the first touch sensing electrode RXA5 in the fifth row and the second touch sensing electrode RXB1 in the first row are substantially located on the same straight line and are insulated from each other in the folding region. That is, the first touch sensing electrode RXA5 in the fifth row and the second touch sensing electrode RXB1 in the first row are four rows apart. The first touch sensing electrode RXA5 in the fifth row and the second touch sensing electrode RXB1 in the first row are substantially located on the same straight line and are insulated from each other in the folding region. Similarly, the first touch sensing electrode RXA6 in the sixth row and the second touch sensing electrode RXB2 in the second row are substantially located on the same straight line and are insulated from each other in the folding region. And so on.
[0093] In the embodiment of the present application, part of the m1 touch drive electrodes of the first touch area AA1 overlaps with the m2 touch drive electrodes of the second touch area AA2. In other words, part of the touch drive electrodes of the first touch area AA1 are included in both the first touch area AA1 and the second touch area AA2. For example, TX5, TX6, TX7, TX8, and TX9 shown in FIG19A are included in both the first touch area AA1 and the second touch area AA2. In this case, the first touch area AA1 includes a total of 9 touch drive electrodes TX, and the second touch area AA2 includes a total of 5 touch drive electrodes TX. Then, corresponding to the first touch area AA1, the nine touch drive electrodes TX and the eleven first touch sensing electrodes RXA can form a capacitor at the intersection of the first touch area AA1 (e.g., the black dots in FIG19A ). The nine touch drive electrodes TX are used to apply touch drive signals. When the touch drive signals are applied, the capacitors output touch sensing signals from the eleven first touch sensing electrodes RXA to sense whether a touch operation has been received within the first touch area AA1 and the location of the touch operation. The five touch drive electrodes TX and the four second touch sensing electrodes RXB in the second touch area AA2 can form a capacitor at the intersection of the second touch area AA2 (e.g., the white dots in FIG19A ). The five touch drive electrodes TX are used to apply touch drive signals. When the touch drive signals are applied, the capacitors output touch sensing signals from the four second touch sensing electrodes RXB to sense whether a touch operation has been received within the second touch area AA2 and the location of the touch operation.
[0094] Optionally, the value of q is related to the covered touch area VII. For example, the greater the maximum distance d1 of the covered touch area VII along the second direction Y, the greater the value of q. For example, when the maximum distance d1 of the covered touch area VII along the second direction Y increases from the value shown in FIG. 19A to the value shown in FIG. 19B , the value of q may correspondingly increase from 4 to 5.
[0095] The value of i is related to the covered touch area VII. For example, the smaller the distance d2 between the covered touch area VII and the edge of the touch panel 201 along the second direction Y, the smaller the value of i. For example, when the distance d2 decreases from the value shown in Figure 19A to the value shown in Figure 19B, the value of i can correspondingly decrease from 4 to 3.
[0096] Optionally, the size of the covered touch area VII is related to the wireless power receiving coil 40. In an optional embodiment, the covered touch area VII is the projection area of the wireless power receiving coil 40 in the third direction Z; in another optional embodiment, the covered touch area VII may include the projection area of the wireless power receiving coil 40 in the third direction Z. For example, the covered touch area VII may be larger than the projection area of the wireless power receiving coil 40 in the third direction Z. When the area of the alternating magnetic field generated by the wireless power transmitting coil 3001 is larger than the projection area of the wireless power receiving coil 40 or the area of the alternating magnetic field generated by the wireless power transmitting coil 3001 is misaligned with the projection area of the wireless power receiving coil 40, the covered touch area VII set in this way is more accurate. It can be seen that in the embodiment of the present application, the covered touch area VII can be set corresponding to the wireless power receiving coil 40, and its specific position is not limited to the position shown in the figure of this embodiment.
[0097] It should be noted that for other specific implementations of this embodiment, please refer to the relevant descriptions in Figures 15A to 16 and will not be repeated here.
[0098] Compared to the previous embodiment, the touch circuit 205 in this embodiment has nine drive channels connected to one end of the nine touch drive electrodes TX, and 15 sensing channels connected to one end of the 11 first touch sensing electrodes RXA and the four second touch sensing electrodes RXB. When the touch circuit 205 sequentially outputs touch drive signals to the nine touch drive electrodes TX, TX1 through TX9, it can receive touch sensing signals from the 11 first touch sensing electrodes RXA and from the four second touch sensing electrodes RXB. Compared to the previous embodiment, this embodiment has fewer touch sensing electrodes RX (the sum of the first touch sensing electrodes RXA and the second touch sensing electrodes RXB), resulting in fewer sensing channels actually used by the touch circuit 205 and lower performance requirements for the touch circuit 205. This means that even a touch circuit 205 with lower performance can still sense whether a touch operation has been received and the location of the touch operation within the first touch area AA1.
[0099] It should be noted that the present embodiment of the present application is described using the example of a touch circuit 205 being connected to one end of a touch drive electrode TX and one end of a touch sensing electrode RX. In other embodiments, the touch circuit 205 can also be connected to both ends of the touch sensing electrode RX simultaneously. In other words, a sensing channel can be connected to both ends of a touch sensing electrode RX simultaneously. For example, as shown in FIG20 , the seven sensing channels of the touch circuit 205 are connected to both ends of RXA1, RXA2, RXA3, RXA4, RXA9, RXA10, and RXA11, respectively. When the touch circuit 205 sequentially outputs touch drive signals to the nine touch drive electrodes TX, touch sensing signals can be simultaneously received from both ends of RXA1, RXA2, RXA3, RXA4, RXA9, RXA10, and RXA11. This effectively reduces the loss of the touch sensing signal during transmission within the first touch sensing electrode RXA, thereby effectively reducing the error in the received touch sensing signal.
