[0050] The embodiments of the present application will be described in detail below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0051] Various modifications and changes can be made to the present application without departing from the spirit and scope of the present application. Therefore, the present application intends to cover the modifications and changes of the present application falling within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the embodiments provided by the present application can be combined with each other without contradiction.

[0052] In order to make the above objectives, features and advantages of the present application more apparent, comprehensible and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0053] As described in the background section, after the external touch screen is combined with the OLED display screen in the electronic device, the performance of the active pen is difficult to modulate, and the accuracy and linearity of the active pen need to be improved.

[0054] This is because the transmitting and receiving electrodes in a touch screen are multiple electrodes, which are crisscrossed in the touch screen to form multiple grids. In contrast, the cathode layer in an OLED display is a single electrode layer. Therefore, there will be a large RC load between the transmitting and receiving electrodes in the touch screen and the cathode layer in the OLED display. This makes it very difficult to debug the performance of the active pen when the electronic device supports the active pen function, and the linearity and accuracy need to be improved.

[0055] It's important to note that performance evaluation metrics for active styluses on touchscreens include tilt, accuracy, linearity, and jitter. These metrics place very strict requirements on the signal transmission between the stylus and the touchscreen. For example, the signal level at each point on the electrodes (TX (transmitting electrode) / RX (receiving electrode)) must be consistent and stable. Therefore, the electrode pattern supporting active stylus functionality must be uniform and linear to maintain a stable signal level. A typical electrode design for active stylus solutions is shown below. Figure 1 As shown, the transmitting electrode 01 and the receiving electrode 02 are located on different layers and are separated by an insulating layer 03. However, the structure of this touch screen is relatively thick.

[0056] The applicant's research found that, in order to reduce the thickness of the touchscreen, the transmitting and receiving electrodes can be placed on the same layer. In the intersection area of ​​the transmitting and receiving electrodes, a bridge structure is used to achieve electrical connection between different parts of the transmitting electrode located on either side of the intersection area, such as... Figure 2 As shown, or, by using a bridge structure, electrical connections can be made between different parts of the receiving electrodes located on both sides of the intersection region, such as... Figure 3 As shown.

[0057] However, when the transmitting electrode and the touch electrode are located on the same layer, the signal transmission channel width changes drastically in the area where the bridge is located. This causes the transmitted signal to fluctuate when the active pen passes through the bridge area, resulting in the active pen's movement trajectory and the display trajectory formed on the electronic device's display surface based on the active pen's movement trajectory not completely coinciding. Figure 4 As shown, Figure 4 The red dots represent the actual touch points of the active pen, while the blue dots represent the display touch point areas that may appear on the screen of the electronic device. This causes the linearity and accuracy of the active pen to fail to meet the specifications of existing active pens, especially with the tilt function having a more severe impact. Specifically, Figure 4 The display point A' and its corresponding actual touch point A may deviate by 40°, the display point B' and its corresponding actual touch point B may deviate by 20°, and the display point C' and its corresponding actual touch point C may deviate by 50°.

[0058] In view of this, embodiments of this application provide a touch module, such as... Figures 5-7As shown, the touch module comprises:

[0059] a transmitting electrode group comprising a plurality of transmitting electrodes 10 arranged along a first direction X for receiving a touch driving signal;

[0060] a receiving electrode group comprising a plurality of receiving electrodes 20 arranged along a second direction Y for outputting a corresponding touch sensing signal, the first direction X and the second direction Y intersecting;

[0061] wherein the transmitting electrodes 10 extend along the second direction Y and the receiving electrodes 20 extend along the first direction X, and the transmitting electrode group and the receiving electrode group are arranged on the same layer.

[0062] Optionally, in an embodiment of the present application, as shown in Figure 5 each transmitting electrode 10 comprises at least two sub-transmitting electrodes arranged at intervals and extending along the first direction, and the different sub-transmitting electrodes in the same transmitting electrode 10 are connected in parallel to reduce the resistance of the transmitting electrode 10. It should be noted that in this embodiment, each channel in the receiving electrode group is provided with a unique sub-receiving electrode extending along the first direction, i.e., each receiving electrode 20 can be a single-channel electrode, i.e., each receiving electrode 20 only comprises a sub-receiving electrode extending along the first direction, so as to reduce the RC load between the transmitting electrode 10 and the electrode layer in the display screen when the touch module is combined with the display screen in the electronic device, and to reduce the difficulty in debugging the performance of the active pen when the electronic device implements the active pen function, and to improve the accuracy and linearity of the active pen.

[0063] Optionally, in an embodiment of the present application, the width of the sub-transmitting electrode ranges from 0.1 mm to 1.5 mm, so as to avoid that the width of the sub-transmitting electrode is too large, which is equivalent to a single-channel transmitting electrode and cannot support or improve the performance of the active pen, and to avoid that the width of the sub-transmitting electrode is too small, which causes a large process difficulty and an insufficient amount of signals in a single sub-transmitting electrode channel, and cannot support the requirements of the active pen. However, the present application is not limited thereto, and the specific value is determined according to the situation.

[0064] In another embodiment of the present application, as shown in Figure 6As shown, each channel in the transmitting electrode group is provided with a unique sub-transmitting electrode extending along the second direction, i.e. each transmitting electrode 10 is a single-channel electrode, that is, each transmitting electrode 10 only includes one sub-transmitting electrode extending along the second direction, and each receiving electrode 20 includes at least two sub-receiving electrodes arranged at intervals and extending along the first direction, and the different sub-receiving electrodes in the same receiving electrode 20 are connected in parallel, so as to reduce the resistance of each receiving electrode 20, thereby reducing the RC load between the receiving electrode 20 and the electrode layer in the display screen when the touch module is combined with the display screen in the electronic device, and reducing the debugging difficulty of the active pen performance when the electronic device implements the active pen function, and improving the accuracy and linearity of the active pen.

[0065] Optionally, in an embodiment of the present application, the width of the sub-receiving electrode ranges from 0.1 mm to 1.5 mm, so as to avoid that the width of the sub-receiving electrode is too large, which is equivalent to a single-channel receiving electrode and cannot support or improve the active pen performance, and avoid that the width of the sub-receiving electrode is too small, which has a large process difficulty and the signal amount in a single sub-receiving electrode channel is insufficient to support the requirements of the active pen. However, the present application is not limited thereto, and the specific value is determined according to the situation.

[0066] In another embodiment of the present application, as shown in Figure 7 each transmitting electrode 10 includes at least two sub-transmitting electrodes arranged at intervals and extending along the first direction, and the different sub-transmitting electrodes in the same transmitting electrode 10 are connected in parallel, so as to reduce the resistance of the transmitting electrode 10, and each receiving electrode 20 includes at least two sub-receiving electrodes arranged at intervals and extending along the first direction, and the different sub-receiving electrodes in the same receiving electrode 20 are connected in parallel, so as to reduce the resistance of each receiving electrode 20, thereby reducing the RC load between the transmitting electrode and the electrode layer in the display screen when the touch module is combined with the display screen in the electronic device, and reducing the RC load between each receiving electrode and the electrode layer in the display screen, reducing the debugging difficulty of the active pen performance when the electronic device implements the active pen function, and improving the accuracy and linearity of the active pen.

[0067] In addition, in the embodiment of the present application, each transmitting electrode includes at least two sub-transmitting electrodes arranged at intervals and extending along the second direction, and the different sub-transmitting electrodes in the same transmitting electrode are connected in parallel, which can also reduce the signal transmission impedance in the transmitting electrode and improve the signal transmission speed in the transmitting electrode; similarly, each receiving electrode includes at least two sub-receiving electrodes arranged at intervals and extending along the first direction, and the different sub-receiving electrodes in the same receiving electrode are connected in parallel, which can also reduce the signal transmission impedance in the receiving electrode and improve the signal transmission speed in the receiving electrode.

[0068] Optionally, in an embodiment of the present application, the transmitting electrode is a metal electrode and the receiving electrode is a metal electrode, so as to further reduce the resistance of the transmitting electrode and the receiving electrode, thereby increasing the signal transmission speed of the transmitting electrode and the receiving electrode, increasing the response speed of the touch control module, and further reducing the RC load between the transmitting electrode and the electrode layer in the display screen and the RC load between the receiving electrode and the electrode layer in the display screen after the touch control module and the display screen are combined.

[0069] In the above embodiment, since the metal electrode has color, when the touch screen is arranged on the display side of the display screen in the electronic device, the display surface of the electronic device including the touch screen and the display screen has problems of electrode pattern visualization and moire, etc., which affect the user experience.

[0070] Moreover, when the metal electrodes in the touch screen are arranged vertically and horizontally above the display screen, part of the metal electrodes are arranged above the opening area of the display screen and part of the metal electrodes are arranged above the non-opening area of the display screen. Since the sizes of pixels with different colors in the display screen are different, the same metal electrode overlapping with pixels with different colors has different proportions of shielding area for pixels with different colors, so that the brightness of part of the area of the electronic device is larger and the brightness of part of the area is smaller, and the display surface of the electronic device has the phenomenon of gray spots.

[0071] Optionally, in an embodiment of the present application, when the touch control module is arranged on the display side of the display screen in the electronic device, in the direction from the display screen to the touch control module, the transmitting electrode is arranged above the non-opening area of the display screen and does not overlap with the opening area of the display screen, and the receiving electrode is arranged above the non-opening area of the display screen and does not overlap with the opening area of the display screen, so as to solve the problems of gray spots on the display surface of the electronic device, pattern visualization and moire, etc. when the touch layer is arranged on the display side of the display screen.

[0072] On the basis of any of the above embodiments, in an embodiment of the present application, the transmitting electrode is a metal electrode and the receiving electrode is a metal electrode, so as to further reduce the resistance of the transmitting electrode and the receiving electrode, thereby increasing the signal transmission speed of the transmitting electrode and the receiving electrode, increasing the response speed of the touch control module, and further reducing the RC load between the transmitting electrode and the electrode layer in the display screen and the RC load between the receiving electrode and the electrode layer in the display screen after the touch control module and the display screen are combined. Figures 5-7As shown, the intersection region of the transmitting electrode 10 and the receiving electrode 20 is provided with a first bridge-crossing structure 30 and a first insulating layer, wherein the first insulating layer is arranged between the transmitting electrode 10 and the receiving electrode 20 to achieve electrical insulation between the transmitting electrode 10 and the receiving electrode 20 in the intersection region and is provided with a first gap. In the embodiment, each transmitting electrode 10 includes a plurality of electrode branches extending in the second direction, and the electrode branches on both sides of the transmitting electrode 10 in the intersection region are electrically connected through the first bridge-crossing structure 30 to achieve electrical connection between different electrode branches in the transmitting electrode 10; and the electrode branches on both sides of the receiving electrode in the intersection region are electrically connected through the first gap to achieve electrical connection between different electrode branches in the receiving electrode. It should be noted that in the above embodiment, one receiving electrode is an entire electrode, and the part of the receiving electrode in the intersection region is the first gap.

[0073] Optionally, in an embodiment of the present application, as shown in FIG. 6, the first bridge-crossing structure 30 is arranged between the transmitting electrode 10 and the receiving electrode 20 in the intersection region, and the first gap is arranged between the transmitting electrode 10 and the receiving electrode 20 in the intersection region. Figure 8 As shown, different sub-transmitting electrodes 11 in the same transmitting electrode 10 are electrically connected at the head end and the tail end of the sub-transmitting electrode 11 to achieve parallel connection of different sub-transmitting electrodes 11 in the same transmitting electrode 10. However, the present application does not limit this, and in other embodiments of the present application, different sub-transmitting electrodes 11 in the same transmitting electrode 10 can also be electrically connected at other positions and / or have more electrical connection positions, depending on the specific situation.

[0074] In the embodiment of the present application, the transmitting electrode includes at least two parallel sub-transmitting electrodes, which can increase the number of intersection regions of the same transmitting electrode and the same receiving electrode, i.e., increase the number of first bridge-crossing structures in the intersection region of the same transmitting electrode and the same receiving electrode, thereby reducing the difference between the channel width at the bridge-crossing position of the same transmitting electrode and the channel width at the non-bridge-crossing position, to reduce the fluctuation amplitude of the transmission signal when the active pen passes through the region where the bridge-crossing is located, improve the stability of the transmission signal, and further reduce the deviation between the motion trajectory of the active pen and the display trajectory formed on the display surface of the electronic device based on the motion trajectory of the active pen, so that the linearity, precision, and inclination of the active pen can meet the specification requirements of the existing active pen.

[0075] Optionally, in an embodiment of the present application, the shape of the electrode branches on both sides of the intersection region of the sub-transmitting electrode 11 can be a quadrilateral, as shown in FIG. 7, or an octagon, as shown in FIG. 8, or other shapes, which are not limited in the present application and depend on the specific situation. Figure 9 Figure 7 Optionally, in an embodiment of the present application, the shape of the electrode branches on both sides of the intersection region of the sub-transmitting electrode 11 can be a quadrilateral, as shown in FIG. 7, or an octagon, as shown in FIG. 8, or other shapes, which are not limited in the present application and depend on the specific situation.

[0076] ​In another embodiment of the present application, the intersection region of the transmitting electrode and the receiving electrode is provided with a second bridge-crossing structure and a second insulating layer, wherein the second insulating layer is arranged between the transmitting electrode and the receiving electrode to achieve electrical insulation of the transmitting electrode and the receiving electrode in the intersection region, and is provided with a second gap. In this embodiment, the electrode branches of the transmitting electrode on both sides of the intersection region are electrically connected through the second gap to achieve electrical connection between different electrode branches of the transmitting electrode; each receiving electrode includes a plurality of electrode branches extending in the first direction, and the electrode branches of the receiving electrode on both sides of the intersection region are electrically connected through the second bridge-crossing structure to achieve electrical connection between different electrode branches of the receiving electrode. It should be noted that in the above embodiment, one of the transmitting electrodes is an entire electrode, and the part of the transmitting electrode located in the intersection region is the second gap.

[0077] Optionally, in one embodiment of the present application, different sub-receiving electrodes in the same receiving electrode are electrically connected at the head end and the tail end of the sub-receiving electrodes respectively to achieve parallel connection of different sub-receiving electrodes in the same receiving electrode, and the present application does not make any limitation thereon, and in other embodiments of the present application, different sub-receiving electrodes in the same receiving electrode can also be electrically connected at other positions and / or have other number of electrical connection positions, which depends on the specific case.

[0078] In the embodiments of the present application, the receiving electrode includes at least two parallel sub-receiving electrodes, which can increase the number of intersection regions of the same receiving electrode and the same transmitting electrode, i.e., increase the number of second bridge-crossing structures of the intersection region of the same transmitting electrode and the same receiving electrode, thereby reducing the difference between the channel width at the bridge-crossing of the same receiving electrode and the channel width at the non-bridge-crossing, so as to reduce the fluctuation amplitude of the transmission signal when the active pen passes through the region where the bridge-crossing is located when supporting the active pen function, improve the stability of the transmission signal, and further reduce the deviation between the motion trajectory of the active pen and the display trajectory formed on the display surface of the electronic device based on the motion trajectory of the active pen, so that the linearity, precision, inclination and other performances of the active pen meet the specification requirements of the existing active pen.

[0079] Optionally, in one embodiment of the present application, the shape of the electrode branches of the sub-receiving electrode on both sides of the intersection region can be quadrilateral, octagonal or other shapes, and the present application does not make any limitation thereon, which depends on the specific case.

[0080] It should be noted that in the embodiment, if the transmitting electrode includes two sub-transmitting electrodes, the receiving electrode includes one sub-receiving electrode, the transmitting electrode and the receiving electrode have two bridge structures, specifically two first bridge structures or two second bridge structures, in the same intersection region of the same transmitting electrode and the same receiving electrode; if the transmitting electrode includes one sub-transmitting electrode, the receiving electrode includes two sub-receiving electrodes, the transmitting electrode and the receiving electrode have two bridge structures, specifically two first bridge structures or two second bridge structures, in the same intersection region of the same transmitting electrode and the same receiving electrode; if the transmitting electrode includes two sub-transmitting electrodes, the receiving electrode includes two sub-receiving electrodes, the transmitting electrode and the receiving electrode have four bridge structures, specifically four first bridge structures or four second bridge structures, in the same intersection region of the same transmitting electrode and the same receiving electrode.

[0081] It should be further noted that the more the number of sub-transmitting electrodes included in the same transmitting electrode and / or the more the number of sub-receiving electrodes included in the same receiving electrode, the more the number of bridge structures the transmitting electrode and the receiving electrode have in the same intersection region of the same transmitting electrode and the same receiving electrode, the smaller the signal fluctuation in the intersection region and the non-intersection region when the transmission signal passes through the intersection region, the more stable the transmission signal, and the better the performance of the active pen.

[0082] In addition, in the embodiment, the transmitting electrode is arranged to include a plurality of parallel sub-transmitting electrodes, and the receiving electrode is arranged to include a plurality of parallel sub-receiving electrodes, and the transmission signals in the signal channels corresponding to adjacent sub-transmitting electrodes can be mutually compensated, and / or the transmission signals in the signal channels corresponding to adjacent sub-receiving electrodes can be mutually compensated, to further improve the stability of the transmission signal.

[0083] In other embodiments of the application, the touch module can further be compensated and optimized by a calculation method to make each transmitting electrode and / or each receiving electrode fit into a complete straight strip, so as to finally realize high-precision calculation and ensure the performance of the active pen, but the application does not limit this, and the specific method is determined according to the situation.

[0084] It should be noted that, in the same intersection region of the same transmitting electrode and the same receiving electrode, the smaller the distance between the multiple first bridge structures or the multiple second bridge structures arranged in the intersection region, the better the effect of improving the stability of signal transmission in the same transmitting electrode and / or the same receiving electrode in the touch module. Optionally, in an embodiment of the present application, if each transmitting electrode includes multiple sub-transmitting electrodes extending in the second direction, in the first direction, the first distance between adjacent transmitting electrodes is greater than the second distance between adjacent sub-transmitting electrodes in the same transmitting electrode, so as to improve the stability of signal transmission in the transmitting electrode; similarly, if each receiving electrode includes multiple sub-receiving electrodes extending in the second direction, in the second direction, the third distance between adjacent receiving electrodes is greater than the fourth distance between adjacent sub-receiving electrodes in the same receiving electrode, so as to improve the stability of signal transmission in the receiving electrode. However, the present application is not limited thereto, and the specific implementation is determined according to the situation.

[0085] It should be noted that, although the touch module provided in the embodiment is described by taking the improvement of the performance of the electronic device supporting the active pen as an example, the present application is not limited thereto, and in other embodiments of the present application, the touch module can also be applied to electronic devices that do not support active pens. If the electronic device is an electronic device that does not support active pens, the touch module is used to detect the touch signal on the surface of the electronic device to determine the touch position, so that the electronic device performs a specific function in response to the touch signal.
