Styluses used in conjunction with touchscreen displays enable extended applications such as handwriting and drawing on the touchscreen.

[0051] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0052] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. To enable those skilled in the art to better understand the solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0053] In the embodiments of this application, it should be noted that, in this document, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0054] Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0055] In the description of the embodiments of this application, the words "example" or "for example" are used to indicate exemplification, illustration, or description. Any embodiment or design described as "example" or "for example" in the embodiments of this application is not to be construed as being more preferred or having more advantages than another embodiment or design. The use of the words "example" or "for example" is intended to present relative concepts in a clear manner.

[0056] Furthermore, in this application embodiment, "multiple" refers to two or more. Therefore, in this application embodiment, "multiple" can also be understood as "at least two." "At least one" can be understood as one or more, such as one, two, or more. For example, including at least one means including one, two, or more, and it does not limit which ones are included. For example, including at least one of A, B, and C, then it could include A, B, C, A and B, A and C, B and C, or A and B and C. It should be noted that in this application embodiment, "and / or" describes the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / ", unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship.

[0057] It should be noted that in the embodiments of this application, "connection" can be understood as electrical connection. The connection between two electrical components can be a direct or indirect connection between the two electrical components. For example, the connection between A and B can be a direct connection between A and B, or an indirect connection between A and B through one or more other electrical components.

[0058] The touch system may include an electronic device and a stylus. The electronic device may be a portable mobile electronic device with a touch display, such as a smartphone, tablet, laptop, or personal digital assistant. The electronic device may also be a smart wearable device; this disclosure does not limit the type of electronic device.

[0059] Electronic devices include a display screen and touch sensors (also known as touch sensors, touch panels, or touch panels), which together form a touch display screen. A touch display screen allows users to perform various functions by touching the sensor panel with their fingers, styluses, or other objects. The display screen can include active-matrix organic light-emitting diode (AMOLED) displays, etc. Touch sensors can include multiple rows (or columns) of sensing electrodes (RX) and multiple columns (or rows) of driving electrodes (TX). The sensing electrodes and driving electrodes are interwoven to form a matrix of multi-point mutual capacitance sensors. These mutual capacitance sensors act as touch nodes, which are the smallest identifiable touch locations. Typically, a touch display screen can recognize multiple touch locations on the touch sensor. In electronic devices such as smartphones and tablets, the touchscreen display is rectangular. The direction of the rows (referred to as the row direction) can be the direction of the shorter side of the rectangle, and the direction of the columns (referred to as the column direction) can be the direction of the longer side of the rectangle. That is, any row electrode extends along the shorter side of the rectangle, and multiple rows of electrodes are arranged along the longer side; any column electrode extends along the longer side of the rectangle, and multiple columns of electrodes are arranged along the shorter side. Alternatively, the row direction can be the direction of the longer side of the rectangle, and the column direction can be the direction of the shorter side of the rectangle. That is, any row electrode extends along the longer side of the rectangle, and multiple rows of electrodes are arranged along the shorter side; any column electrode extends along the shorter side of the rectangle, and multiple columns of electrodes are arranged along the longer side.

[0060] The stylus can be an active stylus. An active stylus can act as a driving electrode, functioning as a driving element excited by an excitation signal to capacitively couple with the sensing and driving electrodes of the touch sensor, thereby forming a capacitive path for coupling charge from the stylus to the sensing and driving electrodes. Specifically, when the stylus tip contacts the touch sensor, the electrodes in the tip are excited to actively generate electric field lines, forming capacitive coupling with the sensing and driving electrodes of the touch sensor.

[0061] When a touch sensor detects an active stylus, the stylus emits a signal at a specific frequency. At this time, the TX and RX electrodes of the touch sensor act as sensing electrodes, independently detecting the received stylus signal. The active stylus threshold values ​​of TX and RX are proportional to the coupling capacitance between TX / RX and the active stylus. Specifically, as the stylus approaches and moves away from the TX (or RX), the threshold value of that TX (or RX) changes with the coupling capacitance. Specifically, the threshold value increases when the stylus is near the center of the TX (or RX), reaches its maximum value when the stylus is at the center of the TX, and decreases when the stylus is far from the center of the TX (or RX). These threshold values ​​are plotted as a curve, forming the threshold value envelope of the stylus. The stylus position can be derived from this threshold value envelope. For a single threshold value envelope with good linearity, the optimal shape is an isosceles triangle. In practice, the optimal shape for a single threshold value envelope is a parabola, which is smooth, symmetrical, monotonous, and consistent. Figure 1A As shown, conventional styluses have relatively thick tips and nibs, generally in a semi-circular shape, while touchscreens are thicker. Regardless of the direction from which the electrodes are approached to or away from, the optimal envelope approximates a parabolic shape. For example... Figure 1B As shown, trajectory A approaches and moves away from D2 laterally, while trajectory B approaches and moves away from D2 diagonally. Figure 1B In this equation, D1, D2, D3, and D4 are one of the sensing electrodes and the driving electrode, and correspondingly, S1, S2, S3, and S4 are the other one. The starting envelope corresponding to trajectory A is as follows: Figure 1C As shown, the coupling capacitance increases as the stylus approaches the center of the touch node and decreases as it moves away from the center of the touch node.

[0062] When styluses are used with electronic devices featuring touchscreen displays such as smartphones, foldable screens, and e-ink screens, there is a growing trend and demand for miniaturized styluse designs to approximate the feel of pencils and styluses, and to make them more portable and compact as accessories for electronic devices. This has led to smaller stylus tips. Furthermore, touchscreen displays are becoming increasingly thinner; for example, the thickness of a standard cover layer has increased from 0.7mm to 0.65mm, 0.6mm, and 0.4mm, while the thickness of a cover layer for foldable screens has increased from 0.35mm to 0.3mm and 0.2mm.

[0063] like Figure 2A As shown, the miniaturized stylus has a thinner, conical tip. With a smaller tip and a thinner touchscreen, the electric field lines between the main electrode and the touch detection electrode of the stylus are more concentrated, without... Figure 1A As shown, the large-scale divergence of the stylus indicates that the area affected by the active stylus is smaller. When the stylus's influence area is smaller, only a small area of ​​the electrodes are coupled, making it more prone to non-uniformity. This leads to distortion of the initial value envelope, making it impossible to achieve the ideal smooth, symmetrical, monotonous, and consistent parabolic shape.

[0064] Please see Figure 2B The touch nodes shown are RX (horizontal electrode) and TX (vertical electrode). The RX electrode consists of 6 vertical strips (the leftmost and rightmost are half strips) plus 2 horizontal strips; the TX electrode consists of 6 vertical strips plus 2 horizontal strips (the top and bottom are half strips). Because the horizontal density of TX is low (2 strips), and the horizontal density of RX is also low (1 strip), the active stylus experiences envelope distortion at these locations, resulting in a non-standard parabola. Taking TX as an example, the 6 vertical strips are relatively dense, so the stylus contact at different positions on the strips does not cause unevenness or envelope distortion. However, the horizontal strips are only 2, with a sparser density. The initial value is larger when the stylus is on the strip, and smaller when the stylus is in the middle, causing envelope distortion and forming a double peak. The middle area, which should be the highest, is flat or even has a lower envelope. Please refer to [link to relevant documentation] for details. Figure 2C As shown.

[0065] Therefore, embodiments of this application provide a touch sensor, such as... Figure 3 As shown, the touch sensor 300 may include: X rows of first electrodes 310 and Y columns of second electrodes 320. The X rows of first electrodes 310 and the Y columns of second electrodes 320 are insulated from each other and are interleaved to form X by Y touch nodes 330. The X rows of first electrodes 310 and the Y columns of second electrodes 320 are uniformly distributed. Specifically, adjacent first electrodes 310 are arranged parallel and at equal intervals along the column direction, and adjacent second electrodes 320 are arranged parallel and at equal intervals along the row direction. In a specific embodiment, in hand detection mode, one of the X rows of first electrodes 310 and the Y columns of second electrodes 320 is a sensing electrode, and the other is a driving electrode. For example, the X rows of first electrodes 310 is a sensing electrode, and the Y columns of second electrodes 320 is a driving electrode; or, the X rows of first electrodes 310 can be a driving electrode, and the Y columns of second electrodes 320 can be a sensing electrode. In pen detection mode, both the X-row first electrode 310 and the Y-column second electrode 320 serve as sensing electrodes. The first electrode 310 generates a row detection signal, and based on the row detection signals generated by each of the X-row first electrodes 310, the row where the stylus is located on the touch sensor can be identified. The second electrode 320 generates a column detection signal, and based on the column detection signals generated by each of the Y-column second electrodes 320, the column where the stylus is located on the touch sensor can be identified, thereby identifying the touch position of the stylus on the touch sensor. In a specific implementation, the first and second electrodes can be conductive patterns, which may include conductive meshes. More specifically, the first and second electrodes can be conductive patterns made of metallic materials, such as metal meshes.

[0066] In some embodiments, the touch area of ​​the touch sensor 300 can be rectangular, with the row direction being the short side of the rectangle and the column direction being the long side of the rectangle. Specifically, the first electrodes 310 in row X extend along the short side of the rectangle and are arranged along the long side, while the second electrodes 320 in column Y extend along the long side of the rectangle and are arranged along the short side. Alternatively, the row direction can be the long side of the rectangle, and the column direction can be the short side of the rectangle. Specifically, the first electrodes 310 in row X extend along the long side of the rectangle and are arranged along the short side between rows, while the second electrodes 320 in column Y extend along the short side of the rectangle and are arranged along the long side between columns. In a specific implementation, the row direction is perpendicular to the column direction. The outer contours of both the first electrode 310 and the second electrode 320 are rectangular, and the outer contour of the touch node 330 formed by the intersection of the first electrode 310 and the second electrode 320 is rectangular.

[0067] In the embodiments of this application, such as Figure 4A As shown, each row of first electrodes 310 includes X1 rows of uniformly distributed first electrode patterns 311. Specifically, each row of first electrode patterns 311 extends along the row direction, and the X1 rows of first electrode patterns 311 are arranged along the column direction. In some specific implementations, the first width of each row of first electrode patterns 311 is equal, which refers to the width of the first electrode pattern 311 at its widest point in the column direction, such as... Figure 4A As shown, the first electrode pattern 311 is rectangular, and its width is uniform along the column direction. The first width is the width of the first electrode pattern 311 along the column direction. If the first electrode pattern 311 has protrusions and concave parts along the column direction, then the first width is the width of the widest part of the first electrode pattern 311 along the column direction. Please continue reading. Figure 4A As shown, the center lines of adjacent rows of first electrode patterns 311 are parallel and equally spaced. "Adjacent" refers to the proximity of the first electrode 310 within itself and between the first electrodes 310, such as... Figure 4A As shown, the distance between the center lines of two adjacent rows of first electrode patterns 311 inside the first electrode 310-1 and the first electrode 310-2, and the distance between the center lines of two adjacent rows of first electrode patterns 311 between the first electrode 310-1 and the first electrode 310-2, is equal to d. Further, as... Figure 5 As shown, the first electrode patterns 311 in each row of the first electrode 310 are symmetrically arranged with respect to the center line of the row of the first electrode 310 in the row direction.

[0068] In the embodiments of this application, such as Figure 4BAs shown, each column of second electrodes 320 includes Y2 columns of fourth electrode patterns 322 evenly distributed. Specifically, each column of fourth electrode patterns 322 extends along the column direction, and the Y2 columns of fourth electrode patterns are arranged along the row direction. The fourth width of each column of fourth electrode patterns 322 is equal, and the fourth width refers to the width of the fourth electrode pattern 322 at its widest point in the row direction. Figure 4B As shown, the fourth electrode pattern 322 is rectangular, and its width is uniform in the column direction. The fourth width is the width of the fourth electrode pattern 322 in the row direction. If the fourth electrode pattern 322 has convex and concave portions in the row direction, then the fourth width is the width of the fourth electrode pattern 322 at its widest point in the row direction. Please continue reading. Figure 4B As shown, the center lines of two adjacent columns of fourth electrode patterns 322 are parallel and equally spaced. "Adjacent" means adjacent both within and between the second electrode 320; that is, the center lines of two adjacent columns of fourth electrode patterns 322 within and between the second electrode 320 are parallel and equally spaced. Figure 4B As shown, the distance between the center lines of two adjacent columns of fourth electrode patterns 322 inside the second electrode 320-1 and the second electrode 320-2, and the distance between the center lines of two adjacent columns of fourth electrode patterns 322 between the second electrode 320-1 and the second electrode 320-2, are both equal to h. Further, as... Figure 5 As shown, the fourth electrode patterns 322 in each column of the second electrode 320 are symmetrically arranged with respect to the center line of the column of the second electrode 320 in the column direction.

[0069] Furthermore, the number of rows of the first electrode pattern 311 and the number of columns of the fourth electrode pattern 322 included in the touch node 330 are both integers greater than or equal to 3, preferably the number of columns of the fourth electrode pattern 322 is greater than or equal to 5. Figure 5 As shown, the touch node 330 may include 3 rows of first electrode patterns 311 and 7 columns of second electrode patterns 322. When the stylus moves along the row direction, the fourth electrode patterns 322 within the touch node 330 can improve the envelope shape; when the stylus moves along the column direction, the first electrode patterns 311 within the touch node 330 can improve the envelope shape, enabling more accurate determination of the stylus's touch position on the touch sensor 300. In this embodiment, if the number of rows of the first electrode patterns 311 included in the touch node 330 is equal to 3, then any row of first electrode patterns 311 is not located at the boundary of the first electrode in the row direction, so that the first electrode patterns 311 are more evenly distributed in the column direction, improving the linearity of touch position detection. If the number of columns of the fourth electrode patterns 322 in the touch node 330 is equal to 3, then any column of fourth electrode patterns 322 is not located at the boundary of the second electrode in the column direction, so that the fourth electrode patterns 322 are more evenly distributed in the row direction, improving the linearity of touch position detection.

[0070] Continue reading Figure 4A As shown, each row of the first electrode 310 may further include X2 columns of uniformly distributed second electrode patterns 312. The second widths of the second electrode patterns 312 are equal, and the second width refers to the width of the second electrode pattern 312 at its widest point in the row direction, such as... Figure 4A As shown, the second electrode pattern 312 is rectangular, and the width of the second electrode pattern 312 is consistent in the row direction. Therefore, the second width is the side length of the second electrode pattern 312 in the row direction. Furthermore, the center lines of adjacent columns of second electrode patterns 312 are parallel and equally spaced. Specifically, as... Figure 4A As shown, the distance between the center lines of any two adjacent columns of the second electrode pattern 312 is equal to e. Further, see [reference needed]. Figure 5 As shown, within the touch node 330, the second electrode pattern 312 and the fourth electrode pattern 322 are arranged alternately in the row direction.

[0071] As one implementation method, see [link / reference] Figure 4A and Figure 5 As shown, in the first electrode 310, two adjacent columns of second electrode patterns 312 in column X2 along the row direction are connected by electrodes in the first electrode pattern 311 in row X1 of the first electrode 310. (Continue reading...) Figure 4B and Figure 5 As shown, the fourth electrode pattern 322 breaks at its intersection with the first electrode pattern 311, and the break is connected via a BRI (Bridge Inductance) connection. (See also...) Figure 5 As shown, adjacent fourth electrode patterns 322 in the column direction are connected one-to-one by conductive bridges BRI.

[0072] Furthermore, the touch node 330 includes a second electrode pattern 312 whose number of columns is an integer greater than or equal to 3. For example... Figure 5 As shown, the touch node 330 includes 8 columns of second electrode patterns 312, where the two outermost second electrode patterns 312 in the row direction are both half the size of the second electrode patterns 312 inside the touch node 330. When the stylus moves in any direction, the first electrode patterns 311 and second electrode patterns 312 inside the touch node 330 can improve the envelope shape, enhance row recognition accuracy, and more accurately determine the touch position of the stylus on the touch sensor.

[0073] Furthermore, such as Figure 6As shown, the touch sensor 300 may include three rows of first electrodes 310 and three columns of second electrodes 320. The three rows of first electrodes 310 are insulated from each other, from each column of second electrodes 320, and from each first electrode 310 to each second electrode 320. The three rows of first electrodes 310 are arranged parallel to each other and at equal intervals along the column direction, and the three columns of second electrodes 320 are arranged parallel to each other and along the row direction. Touch nodes 330 are the intersections of the first electrodes 310 and the second electrodes 320. The three rows of first electrodes 310 and the three columns of second electrodes 320 form a 3x3 array, resulting in a total of nine touch nodes. Each touch node is a repeating unit with the same structure. Specifically, they are first electrode 310-1, first electrode 310-2, first electrode 310-3, second electrode 320-1, second electrode 320-2, and second electrode 320-3, respectively. In each column of the second electrode 320, the fourth electrode pattern 322 of column Y2 is connected to at least one end of the second electrode 320. Specifically, it is connected at one end via line 341 and at the other end via line 342. Lines 341 and 342 can be electrode patterns.

The number of rows of the first electrode patterns 311 in the touch node is an integer greater than or equal to 3, and the number of columns of the second electrode patterns is an integer greater than or equal to 7. In this case, when the stylus moves along the row direction, the fourth electrode patterns 322 in the touch node 330 can improve the envelope shape and improve column recognition accuracy; when the stylus moves in any direction, the first electrode patterns 311 and the second electrode patterns 312 in the touch node 330 can improve the envelope shape and improve row recognition accuracy.

The number of rows of the third electrode pattern included in the touch node is an integer greater than or equal to 3. In this case, when the stylus moves along the column direction, the first electrode pattern 311 and the second electrode pattern 312 in the touch node 330 can improve the envelope shape and improve row recognition accuracy; when the stylus moves in any direction, the fourth electrode pattern 322 and the third electrode pattern in the touch node 330 can improve the envelope shape and improve column recognition accuracy.

The number of rows of the first electrode pattern, the number of columns of the second electrode pattern, the number of rows of the third electrode pattern, and the number of columns of the fourth electrode pattern contained in the touch node are all integers greater than or equal to 3. When the stylus moves in any direction, the first and second electrode patterns in the touch node can improve the envelope shape and improve column recognition accuracy; the third and fourth electrode patterns in the touch node can improve the envelope shape and improve row recognition accuracy, thus more accurately determining the touch position of the stylus on the touch sensor.

The Y2-column fourth electrode patterns 1322 included in the second electrode 1320 are interconnected at one end via line 1341 and at the other end via line 1342. Thus, adjacent touch nodes do not contain connecting lines, avoiding the influence of connecting lines on the starting value envelope, making the starting value closer to the ideal curve, and improving the stylus touch position detection performance.
