Description

Mutual capacitive touch panel and touch system

technical field

The present invention is related to a touch control system, and in particular to a technique for realizing a touch control function by using a single-layer electrode.

Background technique

With the advancement of technology, the operation interfaces of various electronic products have become more and more user-friendly in recent years. For example, through a touch screen, users can directly operate programs and input messages/texts/patterns on the screen with fingers or a stylus, saving the trouble of using input devices such as keyboards or keys. In fact, the touch screen usually consists of a sensing panel and a display disposed behind the sensing panel. The electronic device judges the meaning of the touch according to the position touched by the user on the sensing panel and the picture displayed on the display at that time, and executes the corresponding operation result.

Existing touch technologies are roughly classified into resistive, capacitive, electromagnetic induction, ultrasonic and optical types. Capacitive touch technology can be further divided into two types: self-capacitance and mutual-capacitance. Compared with the mutual-capacitive touch panel, the self-capacitive touch panel can be realized by a single-layer electrode structure with a relatively simple manufacturing process, but there is a problem that it is difficult to achieve a multi-touch function. Therefore, the application range of the mutual capacitive touch panel is much higher than that of the self-capacitive touch panel.

FIG. 1 is an example of a mutual capacitive touch panel. As shown in FIG. 1 , transparent electrodes forming a matrix pattern are arranged behind the sensing panel. In this example, those parallel to the X direction are driving electrodes, and those parallel to the Y direction are receiving electrodes. Each driving electrode is connected to a driver 12 , and each receiving electrode is connected to a receiver 14 . Generally speaking, the drivers 12 send driving signals sequentially, and the receivers 14 continuously receive sensing signals. When a touch occurs, capacitive coupling occurs between the driving electrode and the receiving electrode corresponding to the touch point, resulting in a change in the sensing signal related to the mutual capacitance. According to the position of the driver 12 that sends the driving signal when the touch occurs, and the position of the receiver 14 that detects the change of the induction signal, the subsequent circuit can determine the coordinates of the touch point in the X/Y direction.

Traditionally, the driving electrodes and the receiving electrodes are transparent electrodes respectively arranged on different planes. Figure 2(A) is the most widely used rhombic electrode pattern at present. The dark diamond-shaped electrodes 16 with the same Y coordinates are connected in series to form driving electrodes parallel to the X direction; the light-colored diamond-shaped electrodes 18 with the same X coordinates are connected in series to form driving electrodes parallel to the Y direction. Since the dark diamond-shaped electrodes 16 and the light-color diamond-shaped electrodes 18 are located on different planes, the overlapping parts of the two electrodes are not physically connected in the figure.

In order to reduce material costs, many manufacturers compress the aforementioned double-layer electrode structure into a single-layer electrode structure. In the current single-layer electrode structure, each rhombus main body of the dark-colored rhomboid electrode 16 and the light-colored rhomboid electrode 18 is arranged on the same plane, and the overlapping parts of the two electrodes in FIG. 2(A) are as shown in FIG. 2 (B) Realization of the three-dimensional bridge structure shown. In this example, the connection line between the two dark rhombus electrodes 16 is located on the same plane as the rhombus body, but the connection line between the two light-color rhombus electrodes 18 is designed to be curved (higher than the plane), so that Cross the connection line marked dark in the figure. It can be seen from this that the current single-layer electrode structure is actually not a real single-layer structure. Since the fabrication of the three-dimensional cross-bridge structure is difficult and the yield rate is low, generally speaking, adopting the current single-layer electrode structure for the mutual capacitive touch panel may increase the difficulty and cost of the manufacturing process.

On the other hand, in practice, the driver 12 and the receiver 14 are usually arranged in a circuit chip connected to the sensing panel with a printed circuit board. The more driving/receiving channels (channels) coupled between the sensing panel and the circuit chip, the number of pins of the circuit chip must also increase accordingly, which means higher production cost.

detailed description

An embodiment according to the present invention is a mutual capacitive touch panel, wherein the planar outlines of the driving electrodes and the receiving electrodes are diamond-shaped respectively; FIG. 3(A) is an example of the arrangement of these electrodes. For ease of illustration, FIG. 3(A) only shows three driving electrodes ( D1 - D3 ) and their adjacent receiving electrodes ( R1 - R8 ) in the mutual capacitive touch panel.

The electric force lines that will be affected by the user's touch are mainly distributed between the parallel side lines of the driving electrode and its adjacent receiving electrode. For example, a sensing area is defined between the driving electrode D1 and the receiving electrode R1, and another sensing area is defined between the driving electrode D1 and the receiving electrode R2. By analogy, each of the driving electrodes D1 - D3 corresponds to four different sensing areas. When the controller (not shown) cooperating with the mutual-capacitive touch panel sends a driving signal to the driving electrode D1, the controller can simultaneously make the receiving electrodes R1, R2, R5, and R6 receive the sensing results, and according to this The four sensing results determine whether the user touches the four sensing areas around the driving electrode D1. Similarly, when the controller sends a driving signal to the driving electrode D3, the controller can simultaneously make the receiving electrodes R3, R4, R7, and R8 receive the sensing results, and judge whether the user touches the driving electrode D3 according to these four sensing results Four surrounding sensing areas.

In this embodiment, the controller simultaneously sends a driving signal to the driving electrodes D1 and D3 , and receives sensing results from the receiving electrodes R1 - R8 while sending the driving signal. Since the eight sensing areas R1-R8 corresponding to the driving electrodes D1 and D3 are independent, even if the user touches multiple sensing areas at the same time, the controller can clearly identify them without confusion, so that multi-touch can be realized. Features. For example, if the controller finds that the sensing signals provided by the receiving electrodes R5, R4, and R8 change simultaneously, it can determine that the user touches the three areas marked by dotted lines in FIG. 3(B) at the same time.

It can be seen from the above operation logic that since the controller sends the same driving signal to the driving electrodes D1 and D3 at the same time, the driving electrodes D1 and D3 can share the driving channel connected to the controller. Compared with connecting the driving electrodes D1 and D3 to the controller through different driving channels, sharing the driving channel can save the pins of the chip where the controller is located. Even if the driving channel is not shared, the controller can send driving signals to the driving electrodes D1 and D3 at the same time, so as to save time for scanning the entire mutual-capacitive touch panel. In short, two electrodes that share the same channel must be driven/received at the same time, and two electrodes that do not share the same channel may also be driven/received at the same time.

On the other hand, in order to prevent the controller from confusing the sensing results, when the driving electrodes D1 and D3 share the driving channel connected to the controller, or the controller sends driving signals to the driving electrodes D1 and D3 at the same time, any of the receiving electrodes R1-R8 Two receiving electrodes must not share the receiving channel connected to the controller. In other words, eight different receiving channels must be provided between the receiving electrodes R1-R8 and the controller, corresponding to the receiving electrodes R1-R8 respectively. In practice, the controller can receive the sensing results from the receiving electrodes R1 - R8 at the same time, or can receive the eight sensing results sequentially during the period of sending the driving signal.

In contrast, in this embodiment, since the driving electrodes D1 , D2 correspond to the receiving electrodes R2 , R6 , the controller does not send driving signals to the driving electrodes D1 , D2 at the same time. If the controller sends driving signals to the driving electrodes D1 and D2 at the same time, when the controller finds that the sensing signal provided by the receiving electrode R2 changes, the controller will not be able to distinguish which of the sensing areas marked with dotted lines in Figure 3 (C) is blocked user touches.

FIG. 4(A) further shows more driving electrodes and their adjacent receiving electrodes in the mutual capacitive touch panel according to an embodiment of the present invention. In this embodiment, electrodes that share a channel are labeled with the same name. Taking the two driving electrodes D1 in Figure 4(A) as an example, the four receiving electrodes (R1, R2, R5, R6) corresponding to the left driving electrode D1 and the four receiving electrodes (R1, R2, R5, R6) corresponding to the right driving electrode D1 The receiving electrodes (R3, R4, R7, R8) are not repeated at all, and the receiving channels of these eight receiving electrodes are also different. In other words, as long as the corresponding receiving electrodes and the receiving channels connected to the two driving electrodes are not repeated, the two driving electrodes can share the same driving channel.

From another perspective, two driving electrodes driven by the controller at different time points can physically share at least one receiving electrode (for example, the leftmost driving electrodes D1 and D3 share receiving electrodes R5 and R6), more precisely , can share the receiving electrodes connected to the same receiving channel (for example, the leftmost driving electrodes D1 and D5 share the receiving electrodes R1, R2, R5, R6 of different entities but connected to the same receiving channel).

It should be noted that the designer can selectively allow the driving electrodes/receiving electrodes to share the driving channel/receiving channel according to practical requirements (such as cost or wiring requirements). The embodiment shown in FIG. 4(A) includes driving electrodes sharing a driving channel and receiving electrodes sharing a receiving channel at the same time, and maximizes the number of shared driving channels and shared receiving channels. In the case of no shared channels at all, 12 different driving channels and 20 different receiving channels are originally required; after adopting the sharing concept according to the present invention to maximize the number of shared driving channels and shared receiving channels, only 6 are required Drive channel and 8 receive channels. In another embodiment, the designer can only make the driving electrodes share the driving channel, or make only the receiving electrodes share the receiving channel. In another embodiment, the designer may also make only part of the driving electrodes share the driving channel, or make only part of the receiving electrodes share the receiving channel, needless to say.

FIG. 4(B) further presents one embodiment of the driving channel/receiving channel wiring between these electrodes. It is worth noting that these driving electrodes (D1~D6), receiving electrodes (R1~R8) and channels can all be arranged on the same plane, and the wiring of all driving channels and receiving channels will not overlap with each other, so there is no need The three-dimensional span bridge structure in the prior art. In practice, the number, shape and arrangement of the electrode elements are not limited to the embodiment shown in FIG. 4(B), and these wirings can be arranged more densely to shorten the distance between adjacent electrode elements. It should be noted that the connection of the channels can be realized on the printed circuit board between the touch panel and the controller, and the connection is not limited to the circuit traces of the touch panel itself.

As can be seen from the above description, the mutual capacitive touch panel according to the present invention can meet the needs of adopting a single-layer electrode structure, realizing multi-touch, and reducing the number of pins between the panel and the circuit chip.

Another embodiment according to the present invention is a mutual capacitive touch panel, wherein the planar outlines of the driving electrodes and the receiving electrodes are triangular; FIG. 5(A) shows the arrangement of the electrodes in one embodiment. To keep the drawing clear, the channels connecting the electrodes and the controller are not shown in Figure 5(A); electrodes with the same number are connected to the same channel. The electrodes numbered a~i are fixed receiving electrodes, the electrodes numbered A~F are fixed driving electrodes, and the electrodes numbered 1~8 are variable electrodes (sometimes switched to receiving electrodes, sometimes switched to driving electrodes) . FIG. 5(B) is used to illustrate the operation of the controller setting the variable electrodes 1-8 as receiving electrodes and driving the six driving electrodes A of the left half plane through the same driving channel. The black solid dot marked between the electrodes in FIG. 5(B) is the center position of the sensing area capable of detecting the user's touch under this condition. Figure 5(C) is used to illustrate the operation of the controller when the variable electrodes 1 and 5 are set as driving electrodes and the variable electrodes 3 and 7 are set as receiving electrodes. The black solid dots marked in the figure are In this situation, the center position of the sensing area touched by the user can be detected. By driving the electrodes A-F and the variable electrodes 1-8 alternately and time-sharing, the entire mutual-capacitive touch panel can be completely sensed. The control logic of other electrodes can be deduced in the same way, and will not be repeated here.

As mentioned above, as long as the receiving electrodes corresponding to the two driving electrodes or the receiving channels connected thereto are not repeated, the two driving electrodes can share the same driving channel. In addition, as long as the driving electrodes corresponding to the two receiving electrodes are not driven simultaneously, the two receiving electrodes can share the same receiving channel. It can be seen from FIG. 5(A) that the above embodiment requires a total of 6 driving channels, 9 receiving channels and 8 variable channels; the number of these channels is obviously less than the number of electrodes. Same as the previous embodiment, these electrodes and channels can all be arranged on the same plane, without the need for bridge structures.

Another embodiment according to the present invention is a mutual capacitive touch system further comprising a controller in addition to the aforementioned mutual capacitive touch panel (the pattern can be as shown in Figure 4(A) or Figure 5(A)) . For example, the mutual capacitive touch panel according to the present invention can be integrated into electronic systems such as mobile communication devices, tablet computers, personal computers or interactive information display boards including touch panel controllers.

As mentioned above, in order to take into account the needs of adopting a single-layer electrode structure, realizing multi-touch, and reducing the number of pins between the panel and the circuit chip, the present invention proposes a new mutual-capacitive touch panel and a mutual-capacitive touch panel. The system adopts a single-layer electrode that does not require a three-dimensional bridge structure, and by properly disposing the driving electrode and the receiving electrode, the electrodes can share the channel between the panel and the circuit chip. Compared with the prior art, the panel and the system according to the present invention can effectively reduce the manufacturing process difficulty, save the production cost, and provide the function of multi-touch.

Through the above detailed description of the preferred embodiments, it is hoped that the features and spirit of the present invention can be described more clearly, rather than limiting the scope of the present invention by the preferred embodiments disclosed above. On the contrary, the intention is to cover various changes and equivalent arrangements within the scope of the claimed patent scope of the present invention.
