Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 3, 8-12, the present invention discloses a capacitive touch electrode, including a plurality of driving electrodes 10 and a plurality of sensing electrodes 20 overlapping with the plurality of driving electrodes 10, where each driving electrode 10 includes at least one first hollow portion, the at least one first hollow portion divides the driving electrode 10 into at least 2 driving channels 11 arranged in parallel, each driving electrode 10 further includes a connecting channel 12 connecting adjacent 2 driving channels 11, and at least part of the connecting channel 12 is disposed in a front projection of the sensing electrode 20 on a surface where the driving electrode 10 is located. By detecting the capacitance change at the intersection of the drive channel 11 and the sense electrode 20, the touch position of the finger can be detected. The denser the intersections, the more accurately the touch position can be detected. In fig. 3, in order to clearly show the structure of the connecting channel 12 located right below the sensing electrode 20, the solid line structure of the sensing electrode 20 is not drawn, but the position and structure of the sensing electrode 20 are represented by a dashed line frame, which is the same in fig. 8, 9, 10 and 11, and the position and structure of the sensing electrode 20 are also represented by a dashed line frame.

Each sensing electrode 20 includes at least one second hollow portion, and at least one second hollow portion separates the sensing electrode into at least 2 sensing channels 21 that set up side by side, through detecting the capacitance change of drive channel 11 and the sensing channel 21 crosspoint, can detect the touch position of finger, and the more intensive the crosspoint is, the more accurate touch position that detects.

Referring to fig. 4, one driving channel 11 has a disconnection point 13, the direction of the arrow in the driving channel 11 in fig. 4 is the current direction, by providing the connection channel 12, when one driving channel 11 is disconnected, assuming that the disconnection point 13 is located above the connection channel 12, the current of the other driving channel 11 can be conducted to below the disconnection point 13 of the disconnected driving channel 11 through the connection channel 12, so that the channel below the disconnection point 13 still has current passing, and a capacitance can still be generated between the part of the driving channel 11 having current passing and the sensing channel 21 located above the part of the driving channel, so that the touch position can be detected through the change of the capacitance, and the situation that no current passes through the whole channel is avoided, and the touch position cannot be detected when any position of the whole channel is touched is avoided.

Referring to FIG. 5, which is a diagram illustrating the capacitance change at the intersection of the driving channel 11 and the sensing channel 21 when a finger touches, the capacitance C at the intersection includes the node capacitance Cm (not labeled) at the opposite part of the sensing channel 21 and the driving channel 11 and the fringe capacitance Ce at the intersection edge of the sensing channel 21 and the driving channel 11, i.e., C = Cm + Ce, and the capacitance change Δ C = Cm +. Ce at the intersection point.

Fig. 6 is an equivalent circuit in a normal case, in which TX represents the driving channel 11, RX represents the sensing channel 21, and a finger conducts part of the charges of the fringe capacitance Ce, so as to mainly reduce the magnitude of the fringe capacitance Ce, and the influence on the node capacitance Cm is not large, because the fringe capacitance Ce is conducted to the ground system by the finger, the fringe capacitance Ce becomes small, the capacitance detected by the sensing channel 21 becomes small, and according to the range of the capacitance reduction amount, the touch position can be detected.

Under abnormal conditions, when the finger is in a floating state with respect to the system ground, the finger conducts less charge, the charge at the finger is accumulated continuously, and a floating capacitor Ch is formed, and the equivalent circuit thereof is shown in fig. 7, where TX represents the driving channel 11, RX represents the sensing channel 21, after the floating capacitor Ch is formed, the capacitance C ' detected at the end of the sensing channel 21 is equal to the sum of the node capacitance Cm, the capacitance Cf1 between the driving channel 11 and the finger, and the capacitance Cf2 between the finger and the sensing channel 21, i.e., C ' = Cm + Cf1+ Cf2, if the floating capacitor Ch is large, Cf1 and Cf2 are large, so that the value of C ' is large, the capacitance detected by the sensing channel 21 is not reduced but increased, and the obtained data is abnormal, and the touch position still cannot be detected.

When the capacitive touch electrode is an ultra-thin structure, Cf1 and Cf2 are very large, so that the possibility of generating the above-described abnormal data is greater.

The addition of the connection channel 12 also generates a node capacitance Cm and a fringe capacitance Ce between the connection channel 12 and the sensing channel 21, so that the node capacitance Cm and the fringe capacitance Ce are both increased, and the capacitance variation detected by the sensing channel 21 is affected. When the floating capacitance is generated, the floating capacitance is also increased, which easily causes data abnormality. Therefore, the arrangement position of the connection channel 12 has a great influence on the capacitance variation detected by the sensing channel 21.

Referring to fig. 3, in the present invention, the connection channel 12 is at least partially disposed in the orthographic projection of the sensing electrode 20 on the surface of the driving electrode 10, when a floating capacitance is generated, the sensing electrode 20 covers the lower connection channel 12, so as to avoid a significant increase in capacitance Cf1 between the driving channel 11 and the finger, and at the same time, the capacitance Cf2 between the finger and the sensing channel 21 is substantially unchanged, thereby avoiding an increase in floating capacitance and data anomaly. Since the larger the area of the connection channel 12 in the orthographic projection of the sensing electrode 20 on the driving electrode 10, the smaller the increase of the floating capacitance, it is preferable that the connection channel 12 is completely disposed in the orthographic projection of the sensing electrode 20 on the driving electrode 10.

Further, in an embodiment, referring to fig. 3, 8 to 11, an extending direction of the connecting channel 12 is the same as an extending direction of the sensing channel 21, and the connecting channel 12 is disposed in an orthographic projection of the sensing channel 21 on the surface where the driving electrode 10 is located, that is, an area of the connecting channel 12 is smaller than or equal to an area of the orthographic projection of the sensing channel 21 on the layer where the driving electrode 10 is located, so that the sensing channel 21 is ensured to completely cover the connecting channel 12 located below the sensing channel, thereby avoiding an increase in the floating capacitance.

Further, referring to fig. 3 and 8 to 12, the number of the sensing channels 21 of each sensing electrode 20 may be 2 or more than 2, and the sensing channels 21 are sequentially arranged in parallel, the number of the connecting channels 12 between the adjacent 2 driving channels 11 is less than or equal to the sum of the sensing channels 21 of the plurality of sensing electrodes 20, that is, the number of the connecting channels 12 between the adjacent 2 driving channels 11 is at least 1, and each connecting channel 12 is arranged in the orthographic projection of the sensing channel 21 on the surface where the driving electrode 10 is located, so that the connecting channel 12 is shielded by the sensing channel 21, and the increase of the floating capacitance is avoided. Preferably, each connecting channel 12 is completely blocked by the sensing channel 21, that is, the extending direction of each connecting channel 12 is the same as the extending direction of the sensing channel 21 located above the connecting channel, and each connecting channel 12 is disposed in the orthographic projection of the sensing channel 21 located above the connecting channel in the plane of the driving electrode 10.

Referring to fig. 4, the greater the number of connecting channels 12 between adjacent 2 driving channels 11, the more connecting channels 12 communicate with the adjacent driving channels 11, thereby allowing more areas of the disconnected driving channels 11 to flow current. When the number of the connecting channels 12 between the adjacent 2 driving channels 11 is equal to the number of the sensing channels 21, i.e. one connecting channel 12 covers under each sensing channel 21, the distribution of the connecting channels 12 is the densest, and even if one driving channel 11 has multiple breaks, the effect of the efficacy can be reduced to the minimum.

When the number of the connecting channels 12 between the adjacent 2 driving channels 11 is smaller than the number of the sensing channels 21, the connecting channels 12 between the adjacent 2 driving channels 11 can be uniformly distributed, so that the original capacitance distribution of the whole touch panel is more uniform and the consistency is better.

The touch electrodes may also be distributed unevenly, as long as the performance of the capacitive touch electrodes is not affected, for example, the number of the connection channels 12 may be larger in the easy-to-disconnect region of the driving channel 11, that is, a connection channel 12 is disposed below each sensing channel 21 in the easy-to-disconnect region of the driving channel 11, and the number of the connection channels 12 may be appropriately reduced in the difficult-to-disconnect region of the driving channel 11, that is, it is not necessary to dispose a connection channel 12 below each sensing channel 21.

Referring to fig. 8, the number of the connecting channels 12 between each two adjacent driving channels 11 is equal to the number of the sensing channels 21, and at this time, the number of the connecting channels 12 is the largest and is uniformly distributed, so that not only are more connecting channels 12 communicated with the adjacent driving channels 11, and more areas of the disconnected driving channels 11 have current flowing through, but also the original capacitance distribution of the whole touch panel is more uniform and the consistency is better.

Of course, the number of the connecting channels 12 between the adjacent driving channels 11 may be less than that of the sensing channels 21, and the number of the connecting channels 12 between the adjacent driving channels 11 is not necessarily equal, and may be arbitrarily adjusted as required.

The more the number of the connection channels 12 is, the better, the present invention tests, through simulation, the node capacitance Cm before touch, the increment of the node capacitance Δ Cm after touch, and the magnitude of the floating capacitance after touch of the capacitive touch electrodes with the number of the connection channels 12 between each adjacent driving channels 11 equal to the number of the sensing channels 21 as shown in fig. 8, and the capacitive touch electrodes without increasing the connection channels 12 are comparative examples, and the results are shown in table 1, and can be seen from table 1: the increase of the connection channel 12 increases the dead area between the driving channel 11 and the sensing channel 21, resulting in increasing the Cm value and the Cm value, and after calculation, the Cm/Cm is also decreased from 10.1% to 9.7%, i.e., the sensitivity of the change of Δ Cm is decreased, but the decrease of Δ Cm/Cm is smaller, which does not affect the detection result, and it can also be seen from Table 1: the floating capacitance is reduced from 0.27 pf to 0.26 pf after the connecting channel 12 is added, and the floating capacitance is not increased, which proves that the floating capacitance is not increased when the connecting channel 12 is arranged right below the sensing channel 21.

Table 1: simulation test result

Parameter(s)	Comparative example	Examples of the invention
			Cm/pf	3.79	4.05
∆Cm/pf	0.38	0.39
			∆Cm/Cm	10.1%	9.7%
Suspension capacitor/pf	0.27	0.26

To reduce the facing area between the drive channels 11 and the sense channels 21, avoid a decrease in Cm/Cm, improve sensitivity, the number of connecting channels 12 between adjacent drive channels 11 can be reduced appropriately. Referring to fig. 9 and 10, in an embodiment, the number of the connecting channels 12 between the adjacent driving channels 11 is smaller than the number of the sensing channels 21, and the connecting channels 12 are uniformly distributed on the driving electrode 10, so that the original capacitance distribution of the entire touch panel is more uniform and the uniformity is better.

There are many schemes for uniformly distributing the connecting channels 12, in a specific embodiment, in each driving electrode 10, the connecting channels 12 are arranged in a plurality of rows along the extending direction of the driving channels 11, the connecting channels 12 between two adjacent driving channels 11 are arranged in a row, and the connecting channels 12 in two adjacent rows are arranged in a staggered manner, referring to fig. 9, in this specific embodiment, in each driving electrode 10, the connecting channels 12 in one row are sequentially arranged in the orthographic projection of the sensing channels 21 arranged in odd rows on the plane where the driving electrodes 10 are located, the connecting channels 12 in another adjacent row are sequentially arranged in the orthographic projection of the sensing channels 21 arranged in even rows on the plane where the driving electrodes 10 are located, and the connecting channels 12 in two adjacent rows are arranged in a staggered manner.

In another embodiment, in each driving electrode 10, the connecting channels 12 are arranged in a plurality of rows along the extending direction of the driving channels 11, the connecting channels 12 between two adjacent driving channels 11 are arranged in a column, the distance between the connecting channels 12 in two adjacent rows is greater than the distance between two adjacent sensing channels 21, and the connecting channels 12 in two adjacent columns are arranged in parallel, referring to fig. 10, in this embodiment, in each driving electrode 10, the connecting channels 12 in two adjacent rows are respectively arranged in the orthographic projection of the sensing channels 21 in the odd-numbered or even-numbered adjacent rows on the plane where the driving electrode 10 is located, that is, the distance between the connecting channels 12 in two adjacent rows is equal to the distance between the sensing channels 21 in the odd-numbered adjacent rows.

Of course, other schemes of uniform distribution are also possible, for example, the connecting channels 12 in one column are sequentially distributed in the orthographic projection of the sensing channels 21 of the 1 st and 2 nd, the 5 th and 6 th, the 9 th and 10 th, etc. on the surface where the driving electrode 10 is located, the connecting channels 12 in another adjacent column are sequentially distributed in the orthographic projection of the sensing channels 21 of the 3 rd and 4 th, the 7 th and 8 th, the 11 th and 12 th, etc. on the surface where the driving electrode 10 is located, or the connecting channels 12 in two adjacent rows are respectively sequentially distributed in the orthographic projection of the sensing channels 21 of the 1 st, the 4 th, the 7 th, etc. on the surface where the driving electrode 10 is located, etc.

Further, on the premise of considering the uniform distribution, the number of connection points 15 of each driving channel 11 and the number of connection channels 12 should be as large as possible, and the number of connection points 15 increases, the number of connection channels 12 conducting to the driving channel 11 increases, and when there is a breakpoint in the driving channel 11, it can be maximally ensured that the function of the capacitive touch electrode is not affected. Preferably, referring to fig. 9, in a specific embodiment, in the same driving electrode 10, the connecting points 15 where the driving channel 11 located at the middle position is connected with the connecting channels 12 located at the two sides thereof do not coincide. Further, the number of the connection sites 15 is equal to the total number of the sensing channels 21 of the plurality of sensing electrodes 10, that is, one connection channel 12 is disposed below each sensing channel 21, in this embodiment, the number of the connection channels 12 is equal to the number of the sensing channels 21, which is 4, and the number of the connection sites 15 is also equal to the number of the sensing channels 21, which is also 4. Referring to fig. 10, the driving channel 11 at the middle position has only 2 connecting points 15 with 4 connecting channels 12 at both sides, and the connecting points 15 with 2 connecting channels 12 coincide with each other, and compared with fig. 9 and 10, although the number of the connecting channels 12 is the same and the connecting channels are uniformly distributed, the driving channel 11 at the middle position has more connecting points 15 in the structure shown in fig. 9. Meanwhile, although the total area of the connection channel 12 is the same in fig. 9 and 10, the node capacitance Cm of a single sensing channel 21 is smaller in the structure shown in fig. 9 than in the structure shown in fig. 10 for the single sensing channel 21.

In this embodiment, the driving electrode 10 includes 4 driving channels 11 sequentially arranged in parallel at intervals, and the sensing electrode 20 also includes 4 sensing channels 21 sequentially arranged in parallel at intervals.

Referring to fig. 8, each driving electrode 10 further includes a driving end connector 14 disposed at one end or both ends of the driving electrode 10, the driving end connector 14 being connected to at least 2 driving channels 11 in the same driving electrode 10; each sensing electrode 20 further includes a sensing end connector 22 disposed at one end or both ends of the sensing electrode 20, and the sensing end connector 22 is connected to at least 2 sensing channels 21 in the same driving electrode 20. In this embodiment, both ends of the driving electrode 10 are provided with driving end connections 14, and both ends of the sensing electrode 20 are provided with sensing end connections 22.
