[0036] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be further elaborated in detail below with reference to the accompanying drawings and embodiments. The described embodiments should not be construed as limitations on the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0037] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments. However, it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

It can be understood that "first / second / third" can be interchanged with a specific order or sequence when permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0039] Those skilled in the art of the present technology can understand that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the field to which the embodiments of the present application belong. It should also be understood that terms such as those defined in a general dictionary should be understood to have a meaning consistent with the meaning in the context of the prior art, and will not be interpreted with an idealized or overly formal meaning unless specifically defined as here.

[0040] With the development of the industry, touch display modules can have both touch and display functions. Figure 1A The following is a schematic diagram of the composition structure of a touch display module according to a related art provided by an embodiment of the present application, as Figure 1A shown, the touch display module 10 includes a transparent conductive layer 11, a common electrode layer 12, a liquid crystal layer 13, a sensor layer 14, an insulating layer 15, a gate polarization insulating layer 16, and a touch chip 17.

[0041] In the related art, the touch display module includes a plurality of square-shaped electrodes, and different electrodes are insulated from each other. Figure 1B The following is a schematic diagram of the arrangement of electrodes according to a related art provided by an embodiment of the present application, as Figure 1B shown, the touch drive 18 shows 9 square-shaped electrodes, including a first electrode 181, a second electrode 182, a third electrode 183, a fourth electrode 184, a fifth electrode 185, a sixth electrode 186, a seventh electrode 187, an eighth electrode 188, and a ninth electrode 189. Each electrode is covered with a lead, and a display drive 19 is correspondingly covered on the electrode. The display drive 19 shows strips of three colors: red, green, and blue.

[0042] At the same time, the touch display module adopts a self-capacitance scanning method. Figure 1C The following is a first schematic diagram of induction signals according to a related art provided by an embodiment of the present application, as Figure 1C shown, when a finger touches the touch display module, the touch area 110 corresponding to the touch position covers 5 electrodes, and the coordinates of the position where the touch position is located are located on the fifth electrode 185. Among them, the magnitudes of the induction signals (unit value: C) of the 5 electrodes are respectively: 149, 121, 1814, 143, 139. Figure 1D The following is a schematic diagram of induction signals according to a related art provided by an embodiment of the present application Figure 2 , as Figure 1D shown, when the tip of a pencil touches the touch display module, the touch area 110 corresponding to the touch position only covers the fifth electrode 185. The magnitude of the induction signal of the fifth electrode 185 is 90. It can be seen that for scenarios such as finger touch, the touch area corresponding to the touch position is large enough to cover multiple electrodes. In this way, the touch chip can calculate the coordinates of the position where the touch position is located according to the induction signals received by each electrode. However, in some cases, the touch display module receives a touch operation, and the touch area corresponding to the touch position of the touch operation is small (for example, receiving a touch operation triggered by a passive pen with a small tip, receiving a touch operation triggered by the tip of a pencil, etc.). The induction signal of the electrode is very weak, and even only one electrode can receive the induction signal, resulting in the touch display module being difficult to accurately calculate the position coordinates of the touch position, and there are problems such as low accuracy and poor flexibility.

[0043] An embodiment of the present application provides a touch display module, which includes a liquid crystal layer, a common electrode layer disposed on one side of the liquid crystal layer, and a touch chip. Among them, the common electrode layer includes a plurality of self-capacitance electrodes arranged in a matrix form and insulated from each other. Adjacent two electrodes among the plurality of self-capacitance electrodes are cross-connected. The touch chip can determine the touch position acting on the touch display module by using the induction signals of the plurality of self-capacitance electrodes. In this way, since adjacent two electrodes are cross-connected, even if the area of the touch region corresponding to the touch position is small, induction signals can be generated on a plurality of electrodes, improving the accuracy of calculating the position coordinates of the touch display module and the fineness of the touch display module. At the same time, since the touch display module of the present application can improve the touch accuracy in different touch scenarios, the flexibility of the touch display module is improved.

[0044] Figure 2 FIG. 1 is a schematic diagram of the composition structure of a touch display module provided by an embodiment of the present application. As Figure 2 shown, the touch display module 20 includes a liquid crystal layer 21, a common electrode layer 22, and a touch chip 23, where:

[0045] Liquid crystal layer 21;

[0046] The common electrode layer 22 is disposed on one side of the liquid crystal layer 21. The common electrode layer 22 includes a plurality of self-capacitance electrodes 221 arranged in a matrix form and insulated from each other;

[0047] The touch chip 23 is signal-connected to the plurality of self-capacitance electrodes 221 of the common electrode layer 22 to determine the touch position acting on the touch display module 20 by using the induction signals of the plurality of self-capacitance electrodes 221;

[0048] Among them, adjacent two electrodes among the plurality of self-capacitance electrodes 221 are cross-connected.

[0049] Here, the liquid crystal layer can change its molecular arrangement under the action of an electric field, thereby controlling the polarization direction of light. Therefore, the liquid crystal layer can be used to adjust the light brightness of the light generated by the backlight source.

[0050] The common electrode layer is a conductive layer composed of a plurality of self-capacitance electrodes arranged in a matrix form and insulated from each other. In some embodiments, the common electrode layer can be disposed on any side of the liquid crystal layer, for example, the upper side, the lower side, etc.

[0051] The self-capacitance electrode can detect the capacitance generated when a human body contacts the electrode, and can feedback different capacitance values according to the touched area. In some embodiments, the self-capacitance electrodes are arranged in a matrix form and insulated from each other.

[0052] The touch chip can determine the touch position acting on the touch display module. During implementation, the touch chip can obtain the inductive capacitance signal of the self-capacitance electrode, such as the capacitance value, and then analyze the touch position according to the obtained capacitance value. The inductive signal can be of any suitable magnitude, for example, 90C, 1814C, etc. In some embodiments, the inductive signal can be a signal generated based on the change data of the inductive capacitance signal.

[0053] In some embodiments, the touch chip is signal-connected to multiple self-capacitance electrodes of the common electrode layer, and the connection situation can include but is not limited to one of the following situations: being signal-connected to all the self-capacitance electrodes of the common electrode layer, being signal-connected to some of the self-capacitance electrodes of the common electrode layer.

[0054] In some embodiments, the connection between the touch chip and the self-capacitance electrode can be through lead wires, or without lead wires through inductive connection. The application does not limit the connection method between the touch chip and the self-capacitance electrode.

[0055] In some embodiments, the cross-connection between two adjacent electrodes among multiple self-capacitance electrodes means that there is a cross-connection part between the two adjacent electrodes. Due to the cross-connection between two adjacent electrodes among multiple self-capacitance electrodes, the touch position acting on the touch display module can generate an inductive signal through at least two adjacent electrodes, so that the accurate touch position can be determined by using the inductive signals generated by the adjacent electrodes.

[0056] Figure 3 It is a schematic diagram of arranging self-capacitance electrodes provided for the embodiments of the present application, as Figure 3 shown. The figure shows 9 self-capacitance electrodes, including: the first self-capacitance electrode 31, the second self-capacitance electrode 32, the third self-capacitance electrode 33, the fourth self-capacitance electrode 34, the fifth self-capacitance electrode 35, the sixth self-capacitance electrode 36, the seventh self-capacitance electrode 37, the eighth self-capacitance electrode 38, and the ninth self-capacitance electrode 39. Among them, there is a cross-connection between two adjacent electrodes.

[0057] Compared with Figure 1D in the related art, in the touch display module, only 1 electrode can sense the inductive signal. In the same touch scenario, in the touch display module of the present application, 5 electrodes can sense the inductive signal. Among them, the magnitudes of the inductive signals of the 5 electrodes (unit value: C) are respectively: 23, 32, 75, 15, 18. Therefore, the touch position can be determined more towards which edge or position in the electrode area according to the capacitance values of each electrode; the touch display module of the present application can improve the touch accuracy in different touch scenarios.

[0058] In an embodiment of the present application, the touch display module includes a liquid crystal layer, a common electrode layer disposed on one side of the liquid crystal layer, and a touch chip. Among them, the common electrode layer includes a plurality of self-capacitance electrodes arranged in a matrix form and insulated from each other. Adjacent two electrodes among the plurality of self-capacitance electrodes are cross-connected. The touch chip can determine the touch position acting on the touch display module by using the induction signals of the plurality of self-capacitance electrodes. In this way, since adjacent two electrodes are cross-connected, even if the area of the touch region corresponding to the touch position is small, induction signals can be generated on a plurality of electrodes, improving the accuracy of calculating the position coordinates of the touch display module and the fineness of the touch display module. At the same time, since the touch display module of the present application can improve the touch accuracy in different touch scenarios, the flexibility of the touch display module is improved.

[0059] In some embodiments, the self-capacitance electrode includes an electrode body, a protrusion and a receiving position disposed on the electrode body. The cross-connection between adjacent two self-capacitance electrodes is achieved by the fitting between the corresponding protrusions and receiving positions of each other; and / or, the self-capacitance electrode is a plate structure with a thickness, and the protrusion and the receiving position are disposed on the same edge or different edges of the self-capacitance electrode.

[0060] Here, the electrode body refers to the main sensing part of the self-capacitance electrode. In some embodiments, the projection of the electrode body in the thickness direction can be any suitable shape, such as a triangle, a quadrilateral, a pentagon, a hexagon, etc.

[0061] The protrusion refers to the protruding part on the self-capacitance electrode. The receiving position refers to the groove or cavity structure on the self-capacitance electrode. In some embodiments, each self-capacitance electrode includes an electrode body, and at least one protrusion and one receiving position disposed on the electrode body. Among them, the number of protrusions and receiving positions disposed on each electrode can be the same.

[0062] The self-capacitance electrode is a plate structure with a thickness. The thickness of the self-capacitance electrode can be any suitable size, such as 400 nm (nanometers), 0.33 um (micrometers), etc. In some embodiments, the thickness of the self-capacitance electrode is small, and this design helps to reduce the capacitance delay of the self-capacitance electrode, improve the signal transmission speed of the touch electrode, and make the touch smoother.

[0063] In some embodiments, the protrusion can be in the form of an antenna, and the receiving position can be a notch matching the antenna. Therefore, the protrusion and the receiving position are complementary in shape.

[0064] In some embodiments, there are corresponding protrusions and receiving positions between two adjacent self - capacitive electrodes. Thus, two adjacent self - capacitive electrodes can achieve cross - connection through the engagement between their corresponding protrusions and receiving positions. The so - called cross - connection is only a cross - connection relationship in terms of positional relationship and is not an electrical connection. That is, during implementation, the two adjacent electrodes are insulated from each other.

[0065] In some embodiments, protrusions and receiving positions can be provided at each edge of the self - capacitive electrodes in a specific area of the common electrode layer. The specific area can be any suitable area, such as the central area, the lower - left area, etc.

[0066] In some embodiments, protrusions and receiving positions can be provided at each edge of each self - capacitive electrode in the common electrode layer, or protrusions and receiving positions can be provided at specific edges of each self - capacitive electrode. The specific edges can include, but are not limited to, at least one of the following: the left edge, the right edge, the upper edge, the lower edge, etc.

[0067] In some embodiments, since the protrusions and receiving positions can be set in different ways, a certain edge of the self - capacitive electrode can be provided with only protrusions or receiving positions, or can be provided with both protrusions and receiving positions at the same time. That is to say, the protrusions and receiving positions can be provided on the same edge or different edges of the self - capacitive electrode.

[0068] In the embodiments of the present application, on the one hand, the self - capacitive electrode includes an electrode body and protrusions and receiving positions provided on the electrode body. By optimizing the shape and layout of the electrode, the protrusions and receiving positions can increase the number or contact area of the effective electrodes for sensing fingers or other conductive objects, thereby improving the sensitivity of the touch display module. On the other hand, the protrusions and receiving positions can be provided on the same edge or different edges of the self - capacitive electrode, and the design of the protrusions and receiving positions can be adjusted according to different application scenarios, improving the flexibility and compatibility of the electrode setting.

[0069] In some embodiments, the first self - capacitive electrode in the common electrode layer includes at least one branch structure extending to the area where the adjacent electrode is located, and a gap structure for receiving the branch structure provided on the adjacent electrode; the branch structure constitutes the protrusion on the electrode body, and the gap structure constitutes the receiving position on the electrode body; and / or, the included angle between the extending direction of the gap structure and the extending direction of the branch structure is within a target angle range.

[0070] Here, the first self - capacitive electrode is any one of the electrodes in the common electrode layer. In some embodiments, the first self - capacitive electrode has at least one adjacent electrode.

[0071] The branch structure refers to a structure in the shape of a branch. The extending direction of the branch structure can be any suitable direction, for example, to the right, downward, etc. In some embodiments, the branch structure can form a protrusion on the electrode body.

[0072] The gap structure refers to a structure in the shape of a groove or cavity. The extending direction of the gap structure can be any suitable direction, for example, to the left, upward, etc. In some embodiments, the gap structure can form a receiving position on the electrode body.

[0073] In some embodiments, the first self-capacitance electrode can include at least one branch structure and at least one gap structure. Among them, the sizes of the branch structures can be the same or different, and / or the sizes of the gap structures can be the same or different.

[0074] In some embodiments, the included angle between the extending direction of the gap structure and the extending direction of the branch structure is within a target angle range. The target angle range can be of any suitable size, for example, 0° to 30°, 30° to 60°, 60° to 90°, etc. For example, when the target angle range is 60° to 90°, and the extending direction of the gap structure is horizontally to the left and the extending direction of the branch structure is horizontally upward, the included angle between the extending direction of the gap structure and the extending direction of the branch structure is 90°, which satisfies that the included angle between the extending direction of the gap structure and the extending direction of the branch structure is within the target angle range.

[0075] In some embodiments, the included angle between the extending direction of the gap structure and the extending direction of the branch structure is related to the shape of the electrode body of the first self-capacitance electrode. For example, when the shape of the electrode body of the first self-capacitance electrode is square, the included angle between the extending direction of the gap structure and the extending direction of the branch structure can be 0° or 90°. When the shape of the electrode body of the first self-capacitance electrode is equilateral triangle, the included angle between the extending direction of the gap structure and the extending direction of the branch structure can be 60°.

[0076] In the embodiments of the present application, on the one hand, by forming a protrusion on the electrode body through at least one branch structure extending to the area where the adjacent electrode is located, and forming a receiving position on the electrode body through a gap structure for receiving the branch structure provided on the adjacent electrode, the number or contact area of the effective electrodes for sensing fingers or other conductive objects can be increased, thereby improving the sensitivity of the touch display module; on the other hand, the included angle between the extending direction of the gap structure and the extending direction of the branch structure is within the target angle range, reducing the electric field coupling between adjacent electrodes, thereby reducing the possibility of signal overlap and interference between the electrodes.

[0077] In some embodiments, the electrode body of the first self-capacitance electrode includes a first edge and a second edge that are adjacently arranged; a first branch structure is formed by extending the first edge in a first direction away from the electrode body, a first slit structure is formed by opening the first edge in a second direction toward the electrode body, and the first branch structure and the first slit structure are spaced apart between two ends of the first edge; a second branch structure is formed by extending the second edge in a third direction away from the electrode body, a second slit structure is formed by opening the second edge in a fourth direction toward the electrode body, and the second branch structure and the second slit structure are spaced apart between two ends of the second edge; the first slit structure is disposed at a first position on the first edge close to the second branch structure; and / or, the sizes of the first branch structure and the second branch structure are the same or different, and the sizes of the first slit structure and the second slit structure are the same or different.

[0078] Here, the first self-capacitance electrode includes at least one edge, and the first edge and the second edge are any two suitably adjacently arranged edges.

[0079] In some embodiments, the included angle between the extending direction of the first slit structure and the extending direction of the first branch structure is within a target angle range, that is, the included angle between the first direction and the second direction is within the target angle range, such as 0°.

[0080] In some embodiments, the included angle between the extending direction of the second slit structure and the extending direction of the second branch structure is within a target angle range, that is, the included angle between the third direction and the fourth direction is within the target angle range, such as 10°.

[0081] In some embodiments, the projection of the branch structure (including the first branch structure, the second branch structure, and other branch structures appearing in the text) in the thickness direction can be any suitable shape, for example, a quadrilateral, a triangle, an ellipse, etc. Alternatively, the branch structure can be a structure obtained by combining at least one N-sided polygon, and using the combined branch structure can improve the sensitivity of the touch display module. For example, a triangle and a rectangle can be combined to obtain an arrow-shaped branch structure.

[0082] In some embodiments, since the first branch structure and the first slit structure extend outward and inward along the first edge respectively, the first branch structure and the first slit structure need to be spaced apart at different positions between two ends of the first edge, so that the first edge can simultaneously have the first branch structure extending outward and the first slit structure extending inward, improving the sensitivity of the touch display module.

[0083] The first position refers to a position on the second stub structure. In some embodiments, the first slot structure is disposed at a first position on the first edge close to the second stub structure, so that on the first edge and the second edge, the slot structure and the stub structure can be arranged in an alternating manner. Exemplarily, the arrangement order of the slot structure and the stub structure on the first edge and the second edge can be: the first stub structure, the first slot structure, the second stub structure, and the second slot structure.

[0084] In some embodiments, the first edge and the second edge have a connection point. The first slot structure can be disposed between the two ends of the first edge and close to the connection point, and the first stub structure can be disposed between the two ends of the first edge and far from the connection point. Correspondingly, the second stub structure can be disposed between the two ends of the second edge and close to the connection point, and the second slot structure can be disposed between the two ends of the second edge and far from the connection point.

[0085] In some embodiments, the sizes of the first stub structure and the second stub structure can be the same or different. This is because the first stub structure or the second stub structure needs to match the corresponding slot structure of the adjacent electrode. Therefore, the size of the first stub structure needs to be the same as the size of the slot structure that matches the first stub structure. Similarly, the size of the second stub structure needs to be the same as the size of the slot structure that matches the second stub structure.

[0086] In some embodiments, the size of the stub structure can be represented by the length and the width of the stub structure. The sizes of the first stub structure and the second stub structure being the same means that the length of the first stub structure is the same as the length of the second stub structure, and the width of the first stub structure is the same as the width of the second stub structure.

[0087] In some embodiments, the sizes of the first stub structure and the second stub structure being different can mean that the length of the first stub structure is different from the length of the second stub structure, and / or the width of the first stub structure is different from the width of the second stub structure.

[0088] Exemplarily, the length of the first stub structure is: 90 nm, the length of the second stub structure is: 90 nm, the width of the first stub structure is: 50 nm, and the width of the second stub structure is: 50 nm. It satisfies that the length of the first stub structure is the same as the length of the second stub structure, and the width of the first stub structure is the same as the width of the second stub structure. At this time, the sizes of the first stub structure and the second stub structure are the same.

[0089] In some embodiments, the dimensions of the first slot structure and the second slot structure may be the same or different. This is because the first slot structure or the second slot structure needs to match the corresponding branch structure of the adjacent electrode. Therefore, the dimension of the first slot structure needs to be the same as that of the branch structure that matches the first slot structure. Similarly, the dimension of the second slot structure needs to be the same as that of the branch structure that matches the second slot structure.

[0090] In some embodiments, the dimension of the slot structure can be represented by the length and the width of the slot structure. The same dimensions of the first slot structure and the second slot structure mean that the length of the first slot structure is the same as the length of the second slot structure, and the width of the first slot structure is the same as the width of the second slot structure.

[0091] In some embodiments, the different dimensions of the first slot structure and the second slot structure may mean that the length of the first slot structure is different from the length of the second slot structure, and / or the width of the first slot structure is different from the width of the second slot structure.

[0092] Exemplarily, the length of the first slot structure is: 80 nm, the length of the second slot structure is: 100 nm, the width of the first slot structure is: 40 nm, and the width of the second slot structure is: 30 nm. It satisfies that the length of the first slot structure is different from the length of the second slot structure, and the width of the first slot structure is different from the width of the second slot structure. At this time, the dimensions of the first slot structure and the second slot structure are different.

[0093] In some embodiments, when the shape of the electrode body of the first self-capacitive electrode is square, the electrode body of the first self-capacitive electrode further includes an adjacent third edge and a fourth edge. Among them, a fifth branch structure extends along the seventh direction away from the electrode body on the third edge, and a fifth slot structure is opened along the eighth direction toward the electrode body on the third edge. The fifth branch structure and the fifth slot structure are arranged at intervals between the two ends of the third edge; a sixth branch structure extends along the ninth direction away from the electrode body on the fourth edge, and a sixth slot structure is opened along the tenth direction toward the electrode body on the fourth edge. The sixth branch structure and the sixth slot structure are arranged at intervals between the two ends of the fourth edge; the fifth slot structure is arranged at the second position of the third edge close to the fifth branch structure; and / or the dimensions of the fifth branch structure and the sixth branch structure are the same or different, and the dimensions of the fifth slot structure and the sixth slot structure are the same or different.

[0094] Here, the first self-capacitive electrode includes: a third edge, a fourth edge, a first edge, and a second edge. Among them, the third edge is adjacent to the second edge, and the fourth edge is adjacent to the first edge.

[0095] Figure 4 FIG. 1 is a schematic diagram of a self - capacitive electrode provided by an embodiment of the present application. As Figure 4 shown, the shape of the electrode body of the self - capacitive electrode 41 is square. The self - capacitive electrode 41 includes: a first edge 411, a second edge 412, a third edge 413, and a fourth edge 414. Among them, a first stub structure 4111 and a first slot structure 4112 are arranged at intervals between the two ends of the first edge 411, a second stub structure 4121 and a second slot structure 4122 are arranged at intervals between the two ends of the second edge 412, a fifth stub structure 4131 and a fifth slot structure 4132 are arranged at intervals between the two ends of the third edge 413, and a sixth stub structure 4141 and a sixth slot structure 4142 are arranged at intervals between the two ends of the fourth edge 414.

[0096] In an embodiment of the present application, a stub structure and a slot structure are respectively arranged on the first edge and the second edge of the electrode body of the first self - capacitive electrode. At the same time, the sizes of the stub structure and the slot structure can be different, and the setting methods of the stub structure and the slot structure of the self - capacitive electrode can be flexibly selected according to the actual scenario, improving the flexibility of the touch display module.

[0097] In some embodiments, the first edge and the second edge are perpendicularly arranged, the extending directions of the first stub structure and the second stub structure are perpendicular, and the extending directions of the first slot structure and the second slot structure are perpendicular; and / or, a fifth stub structure is further arranged on the first edge along a first direction, and a fifth slot structure is further arranged along a second direction. The sizes of the fifth stub structure and the first stub structure are different, and the sizes of the fifth slot structure and the first slot structure are different.

[0098] Here, the perpendicular arrangement of the first edge and the second edge means that the included angle between the extending directions of the first edge and the second edge is 90°. At this time, the shape of the projection of the self - capacitive electrode in the thickness direction can be square or rectangular.

[0099] In some embodiments, when the first edge and the second edge are perpendicularly arranged, since the first stub structure is formed by extending along a first direction away from the electrode body on the first edge, and the second stub structure is formed by extending along a third direction away from the electrode body on the second edge, the extending directions of the first stub structure and the second stub structure are perpendicular.

[0100] In some embodiments, when the first edge and the second edge are perpendicularly arranged, since the first slot structure is formed by opening along a second direction towards the electrode body on the first edge, and the second slot structure is formed by opening along a fourth direction towards the electrode body on the second edge, the extending directions of the first slot structure and the second slot structure are perpendicular.

[0101] In some embodiments, since at least one stub structure or slot structure can be provided on the edge, therefore, a fifth stub structure can further be provided along the first direction on the first edge, and a fifth slot structure can further be provided along the second direction. Two parallel stub structures and two parallel slot structures are provided on the first edge.

[0102] In some embodiments, the sizes of the stub structures or slot structures provided on the same edge can be the same or different. For example, the size of the fifth stub structure and the size of the first stub structure can be the same or different, the size of the fifth slot structure and the size of the first slot structure can be the same or different, etc. This is because the fifth stub structure needs to match the corresponding slot structure of the adjacent electrode, and the first stub structure needs to match the corresponding slot structure of the adjacent electrode. Therefore, the size of the fifth stub structure needs to be the same as the size of the slot structure that matches the fifth stub structure. Similarly, the size of the first stub structure needs to be the same as the size of the slot structure that matches the first stub structure.

[0103] In some embodiments, the size of the stub structure can be represented by the length and width of the stub structure. The sizes of the stub structures or slot structures provided on the same edge being the same means that the lengths of the stub structures or the lengths of the slot structures provided on the same edge are the same, and the widths of the stub structures or the widths of the slot structures provided on the same edge are the same.

[0104] Exemplarily, the length of the first stub structure is: 90 nm, the length of the fifth stub structure is: 100 nm, the width of the first stub structure is: 50 nm, and the width of the second stub structure is: 50 nm. It satisfies that the width of the first stub structure and the width of the fifth stub structure are different. At this time, the sizes of the first stub structure and the fifth stub structure are different, that is, the sizes of the stub structures provided on the same edge are different.

[0105] In the embodiments of the present application, the first edge and the second edge are perpendicularly arranged, and a fifth stub structure is further provided along the first direction on the first edge, and a fifth slot structure is further provided along the second direction. At least one stub structure and slot structure can be provided on the edge of the battery body, and the self-capacitive electrodes can be flexibly provided according to actual precision requirements.

[0106] In some embodiments, the sizes of the protrusion and the accommodation part are integer multiples of pixel units; and / or, each self-capacitive electrode is signal-connected to the touch chip through at least one wire, and the self-capacitive electrode and the wire are arranged in different layers.

[0107] Here, a pixel refers to the smallest unit in an image represented by a sequence of numbers. In some embodiments, the pixel unit is related to an RGB pixel unit. An RGB pixel unit refers to an RGB unit composed of at least one sub-pixel. The pixel unit may include, but is not limited to, one of the following: the area of a sub-pixel in an RGB pixel unit, the area of an RGB pixel unit, etc.

[0108] In some embodiments, each self-capacitive electrode can be signal-connected to a touch chip through at least one wire. Therefore, each self-capacitive electrode can be independently controlled, and the touch chip can detect the induction signal of the corresponding self-capacitive electrode through the wire.

[0109] In some embodiments, the wire of the self-capacitive electrode can be covered above the self-capacitive electrode or attached below the self-capacitive electrode. Therefore, the self-capacitive electrode and the wire are arranged in different layers.

[0110] Figure 5 Schematic diagram of a self-capacitive electrode and a wire provided by an embodiment of the present application, as Figure 5 shown, the figure shows 9 self-capacitive electrodes, including: a first self-capacitive electrode 31, a second self-capacitive electrode 32, a third self-capacitive electrode 33, a fourth self-capacitive electrode 34, a fifth self-capacitive electrode 35, a sixth self-capacitive electrode 36, a seventh self-capacitive electrode 37, an eighth self-capacitive electrode 38, and a ninth self-capacitive electrode 39. Among them, adjacent two electrodes are cross-connected, and a wire 50 is covered on each self-capacitive electrode. Each self-capacitive electrode can be signal-connected to a touch chip through at least one wire, and the self-capacitive electrode and the wire are arranged in different layers.

[0111] In the embodiment of the present application, on the one hand, the sizes of the protrusion and the accommodation part are integer multiples of the pixel unit, which can align the electrode structure with the pixel arrangement, reduce the interference of the electrode on the display effect, and thus improve the overall visual experience; on the other hand, arranging the self-capacitive electrode and the wire in different layers can reduce the capacitive coupling and signal interference between the electrode and the wire, and improve the accuracy and reliability of the induction signal.

[0112] In some embodiments, the length of the branch structure is L, the maximum edge length of the electrode body is a, then a / 5 < L < a / 3; the width of the branch structure is W, the minimum edge length of the electrode body is b, then b / 10 < W < b / 5; and / or, the shape of the projection of the electrode body in the direction perpendicular to the thickness direction is at least one of a triangle, a quadrilateral, a pentagon, and a hexagon.

[0113] Here, since the branch structure is formed by extending from the electrode body, the branch structure has corresponding length and width. The length of the branch structure can be of any suitable size, for example, 90 nm, 105 nm, etc. The width of the branch structure can be of any suitable size, for example, 50 nm, 30 nm, etc. In some embodiments, the width of the branch structure can be less than the length of the branch structure.

[0114] In some embodiments, if the length of the branch structure is L and the maximum edge length of the electrode body is a, then a / 5 < L < a / 3 can be satisfied. At the same time, if the width of the branch structure is W and the minimum edge length of the electrode body is b, then b / 10 < W < b / 5 can be satisfied. This is because when the size of the branch structure is close to the size of a pixel and there is a periodic pattern, light interference and diffraction phenomena are likely to occur. Through the above constraints, while enabling the branch structure to receive induction signals, it also reduces the possibility that when the branch structure is too large, the induction signal received by the electrode body is too small.

[0115] In some embodiments, when the electrode body is square, the maximum edge length and the minimum edge length of the electrode body are the same, both denoted by a here, then a / 5 < L < a / 3 can be satisfied, and a / 10 < W < a / 5.

[0116] Figure 6 It is a schematic diagram of the size of a self-capacitive electrode provided by an embodiment of the present application. As Figure 6 shown, the RGB pixel unit 61 includes multiple sub-pixels. The length of the sub-pixel is b1, the width of the sub-pixel is b2. The electrode body of the self-capacitive electrode 62 is square, with both the length and width being a. The length of the branch structure 621 is L, and the width of the branch structure 621 is W, satisfying L = nb2, W = nb1 (n is a natural number), and a / 5 ≤ L ≤ a / 3, a / 10 ≤ W ≤ a / 5.

[0117] In some embodiments, there can be wires between the sub-pixels in the RGB pixel unit. This is an opaque area here. The branch structure can cross the opaque area, so that the problem of light transmittance caused by being located in the middle of the pixel can be avoided, and the possibility of light interference and light diffraction phenomena can be reduced.

[0118] In some embodiments, the shape of the projection of the electrode body in the direction perpendicular to the thickness direction can be at least one of a triangle, a quadrilateral, a pentagon, and a hexagon. Among them, the quadrilateral can include a square and a rectangle, and other shapes can be an equilateral triangle, a regular pentagon, a regular hexagon, etc.

[0119] In an embodiment of the present application, on the one hand, by using constraint conditions to limit the length and width of the stub structure, it is possible to balance between the size of the stub structure and the use effect of the electrode, and reduce the possibility of light interference and diffraction phenomena when the size of the stub structure is unreasonable; on the other hand, since the shape of the projection of the electrode body in the direction perpendicular to the thickness direction is at least one of a triangle, a quadrilateral, a pentagon, and a hexagon, the required shape can be selected according to actual needs, improving the compatibility of the touch display module.

[0120] In some embodiments, the electrode body includes a first end and a second end disposed opposite to each other. The first end extends in a fifth direction to form a third stub structure, and the second end extends in a sixth direction to form a fourth stub structure. The extending directions of the third stub structure and the fourth stub structure are opposite; the third stub structure and the fourth stub structure constitute a protruding portion on the electrode body; a first gap and a second gap are respectively formed between the third stub structure, the fourth stub structure and the electrode body, and the first gap and the second gap form a receiving position on the electrode body; and / or, the touch display module further includes a pressure sensing detection chip signal-connected to the common electrode layer, and the pressure sensing detection chip can detect pressure signals by using the self-capacitance electrodes of the common electrode layer.

[0121] Here, the electrode body can be a quadrilateral, and any pair of parallel edges in the quadrilateral can be selected, and the first end and the second end are oppositely disposed with different extending directions.

[0122] In some embodiments, the first end extends in a fifth direction to form a third stub structure, and the second end extends in a sixth direction to form a fourth stub structure. Among them, the fifth direction can be any suitable direction, for example, left or down. The sixth direction can be any suitable direction, for example, right or up.

[0123] In some embodiments, the extending directions of the third stub structure and the fourth stub structure are opposite, that is, the fifth direction and the sixth direction are opposite. For example, when the fifth direction is down, the sixth direction can be up.

[0124] In some embodiments, the third stub structure and the fourth stub structure constitute a protruding portion on the electrode body. A first gap is formed between the third stub structure and the electrode body, and a second gap is formed between the fourth stub structure and the electrode body. The first gap and the second gap form a receiving position on the electrode body. During implementation, the third stub structure and the fourth stub structure can be respectively disposed at the top positions of the first end and the second end, so that a first gap and a second gap are respectively formed between the third stub structure, the fourth stub structure and the electrode body.

[0125] In some embodiments, the size of the third branch structure and the size of the fourth branch structure may be the same or different. The size of the third branch structure and the size of the fourth branch structure being the same means that the length of the third branch structure is the same as the length of the fourth branch structure, and the width of the third branch structure is the same as the width of the fourth branch structure. The size of the third branch structure and the size of the fourth branch structure being different may mean that the length of the third branch structure is different from the length of the fourth branch structure, and / or the width of the third branch structure is different from the width of the fourth branch structure.

[0126] In some embodiments, the size of the gap can be represented by the length of the gap and the width of the gap. The size of the first gap and the size of the second gap may be the same or different. The size of the first gap and the size of the second gap being the same means that the length of the first gap is the same as the length of the second gap, and the width of the first gap is the same as the width of the second gap. The size of the first gap and the size of the second gap being different may mean that the length of the first gap is different from the length of the second gap, and / or the width of the first gap is different from the width of the second gap.

[0127] Figure 7 Schematic diagram of a self-capacitive electrode provided by an embodiment of the present application Figure 2 , such as Figure 7 shown, the electrode body 71 of the self-capacitive electrode 70 is rectangular. The electrode body 71 includes a first end 711 and a second end 712 which are oppositely arranged. A third branch structure 7111 is formed by extending from the first end 711, and a fourth branch structure 7121 is formed by extending from the second end 712 in the sixth direction. A first gap 7112 and a second gap 7122 are respectively formed between the third branch structure 7111, the fourth branch structure 7111 and the electrode body 71.

[0128] In some embodiments, the touch display module further includes a pressure sensing detection chip signal-connected to the common electrode layer. The pressure sensing detection chip can use the self-capacitive electrode of the common electrode layer to detect pressure signals. Through the self-capacitive electrode and the pressure sensing detection chip, when the touch display module receives an applied pressure, the capacitance value of the self-capacitive electrode will change. The pressure sensing detection chip can detect this change and convert it into a pressure signal.

[0129] In an embodiment of the present application, on the one hand, stub structures are formed by extending at both ends of the electrode body, and protrusions and accommodation positions are formed with the electrode body through the stub structures, which can achieve cross-connection of adjacent electrodes, increase the number or contact area of effective electrodes for sensing fingers or other conductive objects, thereby improving the sensitivity of the touch display module. At the same time, by arranging stub structures at both ends, the electric field distribution around the electrodes can be optimized; on the other hand, the pressure sensing chip connected to the common electrode layer signals is used to detect pressure signals, making full use of the existing electrode structure in the touch display module and avoiding the complexity and cost increase brought by adding additional pressure sensors.

[0130] The following describes the application of the touch display module provided in the embodiment of the present application in an actual scenario.

[0131] With the development of the industry, the touch display module can have both touch and display functions. In related technologies, the touch display module includes a plurality of square-shaped electrodes that are insulated from each other. At the same time, the touch display module adopts a self-capacitance scanning method. For scenarios such as finger touch, the touch area corresponding to the touch position is large enough to cover multiple electrodes. In this way, the touch chip can calculate the coordinates of the position where the touch position is located according to the induction signals received by each electrode. However, in some cases, when the touch display module receives a touch operation, the touch area corresponding to the touch position of the touch operation is small (for example, receiving a touch operation triggered by a passive pen with a small nib, receiving a touch operation triggered by a pencil nib, etc.), the induction signal of the electrode is very weak, and even only one electrode can receive the induction signal, resulting in the touch display module being difficult to accurately calculate the position coordinates of the touch position, and there are problems such as low accuracy and poor flexibility.

[0132] An embodiment of the present application provides a touch display module, including a liquid crystal layer, a common electrode layer disposed on one side of the liquid crystal layer, and a touch chip. Among them, the common electrode layer includes a plurality of self-capacitance electrodes arranged in a matrix form and insulated from each other. Adjacent two electrodes among the plurality of self-capacitance electrodes are cross-connected, and the touch chip can determine the touch position acting on the touch display module by using the induction signals of the plurality of self-capacitance electrodes. In this way, since adjacent two electrodes are cross-connected, even if the touch area corresponding to the touch position is small, induction signals can be generated on multiple electrodes, improving the accuracy of the touch display module in calculating position coordinates and the fineness of the touch display module. At the same time, since the touch display module of the present application can improve the touch accuracy in different touch scenarios, the flexibility of the touch display module is improved.

[0133] Figure 8A FIG. 1 is a schematic diagram of a usage scenario of a touch display module provided in an embodiment of the present application, as Figure 8AAs shown, the touch display module 81 of the related art and the touch display module 82 of the present application have the same size and the same size of the electrodes. The touch display module 81 of the related art includes a plurality of electrodes. Taking one of the target electrodes 811 as an example, the shape of the target electrode 811 is square. The touch display module 82 of the present application includes a plurality of self-capacitive electrodes, and each self-capacitive electrode is connected to the pin of the touch chip, which is called a signal channel. Taking one of the target self-capacitive electrodes 821 as an example, the target self-capacitive electrode 821 includes an electrode body and a protrusion and a receiving position provided on the electrode body, and the target self-capacitive electrode 821 is cross-connected with adjacent electrodes.

[0134] In this scenario, compared with the touch display module 81 of the related art, the size of the touch display module 82 of the present application remains unchanged, but through the cross-connected self-capacitive electrodes, the pencil or passive pen signal can be sensed by multiple self-capacitive electrodes, thereby improving the coordinate calculation accuracy and the accuracy and linearity of writing and drawing. It also helps to some extent for the touch of fingers and active pens.

[0135] Figure 8B Schematic diagram of the usage scenario of a touch display module provided by an embodiment of the present application Figure 2 , as Figure 8B shown, the number of electrodes of the touch display module 81 of the related art and the touch display module 82 of the present application is the same, and the size of the electrodes of the touch display module 82 of the present application is larger than that of the touch display module 81 of the related art. The touch display module 81 of the related art includes a plurality of electrodes. Taking one of the target electrodes 811 as an example, the shape of the target electrode 811 is square. The touch display module 82 of the present application includes a plurality of self-capacitive electrodes. Taking one of the target self-capacitive electrodes 821 as an example, the target self-capacitive electrode 821 includes an electrode body and a protrusion and a receiving position provided on the electrode body, and the target self-capacitive electrode 821 is cross-connected with adjacent electrodes.

[0136] In this scenario, when the number of electrodes of the touch display module is the same, compared with the touch display module 81 of the related art, since the size of the electrodes of the touch display module 82 of the present application is larger on the premise that the number of electrodes is the same, therefore, the present application can support a larger size on the premise that the number of signal channels remains unchanged. At the same time, since two adjacent electrodes are cross-connected, the accurate detection of the induction signal can also be maintained.

[0137] Figure 8C Schematic diagram of the usage scenario of a touch display module provided by an embodiment of the present application Figure 3 , as Figure 8CAs shown, the size of the electrodes of the touch display module 82 of the present application is larger than that of the electrodes of the touch display module 81 in the related art, and the size of the touch display module 81 in the related art is the same as that of the touch display module 82 of the present application. The touch display module 81 in the related art includes a plurality of electrodes. Taking one target electrode 811 as an example, the shape of the target electrode 811 is square. The touch display module 82 of the present application includes a plurality of self-capacitive electrodes. Taking one target self-capacitive electrode 821 as an example, the target self-capacitive electrode 821 includes an electrode body, a protrusion and a receiving position provided on the electrode body, and the target self-capacitive electrode 821 is cross-connected with adjacent electrodes.

[0138] In this scenario, when the sizes of the touch display modules are the same, compared with the touch display module 81 in the related art, since the size of the electrodes of the touch display module 82 of the present application is larger, therefore, the present application can adopt fewer signal channels, thereby reducing the cost of the touch display module. At the same time, since two adjacent electrodes are cross-connected, the accuracy of detecting the induction signal can also be maintained.

[0139] Based on the above embodiments, the embodiments of the present application further provide an electronic device. Figure 9 It is a schematic structural diagram of an electronic device provided by an embodiment of the present application. As Figure 9 shown, the electronic device 900 includes:

[0140] A device body 901;

[0141] A controller 902;

[0142] A touch display module 20 disposed in the device body 901 and signal-connected to the controller 902;

[0143] Among them, the touch display module 20 includes:

[0144] A liquid crystal layer 21;

[0145] A common electrode layer 22 disposed on one side of the liquid crystal layer 21. The common electrode layer 22 includes a plurality of self-capacitive electrodes 221 arranged in a matrix form and insulated from each other;

[0146] A touch chip 23, signal-connected to a plurality of self-capacitive electrodes 221 of the common electrode layer 22, to determine the touch position acting on the touch display module 20 by using the induction signals of the plurality of self-capacitive electrodes 221;

[0147] Among them, adjacent two of the plurality of self-capacitive electrodes 221 are cross-connected;

[0148] The controller 902 can control the electronic device 900 to perform corresponding response operations based on the touch position sensed by the touch chip 22.

[0149] Here, the device body has a certain accommodation space, which can wrap the controller and the touch display module.

[0150] The controller is a device that can control and adjust an electronic device. In some embodiments, the controller may include, but is not limited to, at least one of the following: a panel controller (PNC), an embedded controller (EC), a central processing unit (CPU), etc. The PNC can be used to control the operation of the panel, the EC can be used for the underlying control of the embedded system, and the CPU is the core processing unit of the computer system. The specific form of the controller in this application is not limited.

[0151] In some embodiments, the touch display module can be in any suitable form, for example, a touch screen, a touch pad, etc. The touch screen is an input device integrated on a display device. The touch pad is a planar input device. Both the touch screen and the touch pad can determine corresponding induction signals according to the received touch operations.

[0152] The liquid crystal layer can change its molecular arrangement under the action of an electric field, thereby controlling the polarization direction of light. Therefore, the liquid crystal layer can be used to adjust the light brightness of the light generated by the backlight source.

[0153] The common electrode layer is a conductive layer composed of a plurality of self-capacitance electrodes arranged in a matrix form and insulated from each other. In some embodiments, the common electrode layer can be disposed on either side of the liquid crystal layer, for example, the upper side, the lower side, etc.

[0154] The self-capacitance electrode can detect the capacitance generated when a human body contacts the electrode, and can feedback different capacitance values according to the touched area. In some embodiments, the self-capacitance electrodes are arranged in a matrix form and insulated from each other.

[0155] The touch chip can determine the touch position acting on the touch display module. During implementation, the touch chip can obtain the induction capacitance signal of the self-capacitance electrode, such as the capacitance value, and then analyze the touch position according to the obtained capacitance value. The induction signal refers to the signal detected by the touch chip. The induction signal can be of any suitable magnitude, for example, 90, 1814, etc. In some embodiments, the induction signal can be a signal generated according to the change data of the induced capacitance signal.

[0156] In some embodiments, the cross-connection between two adjacent electrodes among multiple self-capacitive electrodes means that there is a cross-connection portion between the two adjacent electrodes. Since there is a cross-connection between two adjacent electrodes among multiple self-capacitive electrodes, the touch position acting on the touch display module can generate induction signals through at least two adjacent electrodes, so that the accurate touch sensing position can be determined by using the induction signals generated by the adjacent electrodes.

[0157] In the embodiments of the present application, the electronic device includes a device body, a controller, and a touch display module disposed in the device body and signal-connected to the controller. Among them, the touch display module includes a liquid crystal layer, a common electrode layer disposed on one side of the liquid crystal layer, and a touch chip. The common electrode layer includes multiple self-capacitive electrodes arranged in a matrix form and insulated from each other. There is a cross-connection between two adjacent electrodes among the multiple self-capacitive electrodes. The touch chip can determine the touch position acting on the touch display module by using the induction signals of the multiple self-capacitive electrodes. In this way, due to the cross-connection between two adjacent electrodes, even if the area of the touch region corresponding to the touch position is small, induction signals can be generated on multiple electrodes, improving the accuracy of calculating the position coordinates of the touch display module and the fineness of the electronic device. At the same time, since the electronic device of the present application can improve the touch accuracy in different touch scenarios, the flexibility of the electronic device is improved.

[0158] In some embodiments, the controller can also adjust the touch control parameters of the touch chip based on the display configuration information of the touch display module; and / or, the device body includes a first body and a second body that are rotatably connected, and the touch display module is disposed on the first body and / or the second body.

[0159] Here, the display configuration information may include, but is not limited to, at least one of the following: display screen size, resolution, display technology type, etc. The display screen size can be any suitable size, for example, 14 inches, 16 inches, etc. The resolution can be any suitable size, for example, 1920×1080 ppi (pixels per inch), 1280×720 ppi, etc. The display technology type may include, but is not limited to, at least one of liquid crystal display, organic light-emitting diode, etc.

[0160] The touch control parameters may include, but are not limited to, at least one of the following: touch sensitivity, touch firmware (FW), touch technology type, etc. Touch sensitivity refers to the ability of the touch screen to sense slight touches. The touch sensitivity can be any suitable degree, for example, high sensitivity, medium sensitivity, low sensitivity, etc. Touch FW refers to the software program embedded in the touch display module. The touch technology type may include, but is not limited to, at least one of the following: resistive touch, capacitive touch, infrared touch, acoustic wave touch, etc.

[0161] The first body and the second body are partial bodies of an electronic device. The first body and the second body can be rotatably connected. In some embodiments, the first body and the second body can be rotatably connected through a mechanical structure. For example, in a folding screen device, the rotatable connection between the first body and the second body enables the device to flexibly switch its form in different scenarios.

[0162] In some embodiments, the touch display module can be disposed only on the first body or the second body according to the specific functional requirements and structural design of the device, or can be disposed on both the first body and the second body at the same time.

[0163] In some embodiments, a correspondence relationship between display configuration information and touch control parameters can be established. After the controller detects the display configuration information, according to this correspondence relationship, the controller can use the display configuration information of the touch display module to adjust the touch control parameters of the touch chip.

[0164] In some embodiments, the touch display module or the electronic device has a corresponding usage mode. For example, the usage mode can include but is not limited to: display output for its own system, display output for screen mirroring data, etc. The controller can adjust the touch control parameters of the touch chip based on the usage mode and the display configuration information.

[0165] In the embodiments of the present application, on the one hand, the controller can dynamically adjust the touch control parameters based on the display configuration information, which can ensure that the electronic device in different states maintains good display performance, thereby improving the intelligence level of the electronic device; on the other hand, the device body includes a first body and a second body that are rotatably connected, and the touch display module is disposed on the first body and / or the second body, and the electronic device can flexibly switch its form in different usage scenarios, improving the compatibility of the electronic device.
