Description

Touch control system
Technical Field
The disclosure relates to the field of touch technologies, and in particular, to a touch system.
Background
The protocol of the active pen (protocol) is consistent with the protocol of the Touch controller of the Touch Panel (TP) to be compatible. However, due to various factors, such as new products, price or performance, etc., existing active pens and touch controllers have many different protocols, active pens and touch controllers with different protocols are not compatible, such that the application of active pens is limited.
In addition, manufacturers can produce active pens with different protocols according to requirements, which is inconvenient for the manufacturers to maintain the active pens with different protocols.
Although there are active pens and touch controllers supporting a plurality of different protocols, the touch controller cannot determine which protocol may have better performance. When the active pen and the touch controller can communicate through multiple protocols, the active pen needs to use a key switching protocol, and the touch controller needs to use software or the key switching protocol. The protocol of the active pen and the protocol of the touch controller are not compatible because of possible switching errors or false key touches. In short, the touch controller may only communicate with the protocol that is successful in the first connection, and the touch controller may not select the protocol with the best performance from the available protocols for communication.
There is therefore a need to propose a solution to the above-mentioned problems of the prior art.

Detailed Description
For the purpose of making the objects, technical solutions and effects of the present disclosure clearer and more specific, the present disclosure will be described in further detail below with reference to the drawings and examples. It should be understood that the particular embodiments described herein are merely illustrative of the present disclosure, and that the word "embodiment" as used in the specification is intended to be used as an example, illustration, or instance and is not intended to limit the present disclosure. Furthermore, the articles "a" and "an" as used in this specification and the appended claims may generally be construed to mean "one or more" unless specified otherwise or clear from context to be directed to a singular form. Moreover, in the drawings, structural, functional similarity or identity elements are identified by the same element numerals.
Referring to fig. 1 and 2, fig. 1 is a schematic diagram of a touch system according to an embodiment of the disclosure. Fig. 2 shows a schematic diagram of a touch panel 10 and a touch controller 20.
The touch system includes the touch panel 10, the touch controller 20 and an active pen 30.
The active pen 30 is used to generate a signal. The touch controller 20 is electrically connected to the touch panel 10 and is used for detecting the signal. The signal is, for example, generated when the active pen 30 touches the touch panel 10, i.e. the signal is a touch signal. Alternatively, the signal is generated when the active pen 30 is suspended on the touch panel 10, i.e. the signal is a suspension signal.
Referring to fig. 1 to 3, fig. 3 is a schematic diagram showing a coupling capacitor Cm formed between a driving electrode 12 and a sensing electrode 14 of the touch panel 10.
As shown in fig. 2, the touch panel 10 generally includes a plurality of electrodes arranged in a matrix and wires connecting the plurality of electrodes, wherein the plurality of electrodes are made of Indium Tin Oxide (ITO), and the plurality of electrodes are generally shaped as bars (bars) or Diamond (Diamond). In the mutual capacitance (Mutual Capacitance) architecture, the plurality of electrodes includes a plurality of driving electrodes 12 (shown in fig. 3) and a plurality of sensing electrodes 14 (shown in fig. 3), and accordingly, the conductive lines also include a plurality of driving conductive lines 16 and a plurality of sensing conductive lines 18, the plurality of driving conductive lines 16 are individually connected to the plurality of driving electrodes 12, and the plurality of sensing conductive lines 18 are individually connected to the plurality of sensing electrodes 14. The mutual capacitance architecture is driven by sequentially applying a Panel driving signal tp_tx (TP stands for Touch Panel) to the plurality of driving electrodes 12 through the plurality of driving wires 16, wherein the Panel driving signal tp_tx is usually a pulse signal, and correspondingly, the sensing signal tp_rx is sequentially read from the plurality of sensing electrodes 14 through the plurality of sensing wires 18.
As shown in fig. 1, the active pen 30 (also called an active stylus or capacitive pen) can produce an effect similar to that of touching the touch panel 10 of fig. 1 with a finger, that is, changing the capacitance value of the coupling capacitance Cm between the driving electrode 12 and the sensing electrode 14 of fig. 3. Alternatively, the floating signal of the active pen 30 may change the capacitance value of the coupling capacitance Cm between the driving electrode 12 and the sensing electrode 14 of fig. 3.
The active pen 30 includes a housing 32, a transmitting portion 34, a receiving portion 36, a pressure sensing assembly 38, and a control unit 40.
The housing 32 has a hollow structure. The transmitting portion 34 is disposed at an outward extension of one end of the housing 32. The receiving portion 36 is disposed inside the end of the housing 32. The pressure sensing assembly 38 extends outwardly from the transmitter 34. The control unit 40 is disposed inside the housing 32 and electrically connected to the transmitting portion 34, the receiving portion 36 and the pressure sensing component 38.
The positions where the transmitting unit 34 and the receiving unit 36 are provided are not limited to the positions shown in fig. 1, and the transmitting unit 34 and the receiving unit 36 may be provided at appropriate positions as required.
Referring to fig. 1 to 5, fig. 4 shows a timing chart of the active pen 30 detecting that the protocol of the touch controller 20 is a unidirectional protocol. Fig. 5 shows a timing diagram of the active pen 30 detecting that the protocol of the touch controller 20 is a two-way protocol.
One feature of the present disclosure is that the stylus 30 can automatically detect the protocol of the touch controller 20 and switch the protocol of the stylus 30 to the protocol of the touch controller 20. More specifically, the active pen 30 can automatically detect whether the protocol of the touch controller 20 is one-way protocol (fig. 4) or two-way protocol (fig. 5). When the protocol of the touch controller 20 is a one-way protocol, it means that the touch controller 20 only receives the active pen signal transmitted by the transmitting portion 34 of the active pen 30 and does not transmit a controller signal. When the protocol of the touch controller 20 is a two-way protocol, it means that the touch controller 20 transmits a controller signal having the two-way protocol and receives an active pen signal transmitted by the transmitting part 34 of the active pen 30.
In fig. 4, the protocol of the touch controller 20 is a unidirectional protocol, so that no controller signal is sent. When the receiving portion 36 of the active pen 30 does not receive the controller signal, the transmitting portion 34 of the active pen 30 transmits an active pen signal having a unidirectional protocol to the touch controller 20 through the plurality of sensing electrodes 14 in a period T1, and then the receiving portion 36 of the active pen 30 detects whether the touch controller 20 transmits the controller signal in a period T2. Since the protocol of the touch controller 20 is a one-way protocol, it means that the touch controller 20 will not send a controller signal, and therefore the receiving unit 36 of the active pen 30 does not receive the controller signal, the controller 40 of the active pen 30 determines that the protocol of the touch controller 20 is a one-way protocol.
In fig. 5, the protocol of the touch controller 20 is a bi-directional protocol, so the touch controller 20 transmits a controller signal having the bi-directional protocol. It should be noted that, when the protocol of the touch controller 20 is a bidirectional protocol, the touch controller 20 first sends a signal (i.e., a controller signal).
When the receiving unit 36 of the active pen 30 receives the controller signal with the bi-directional protocol sent by the touch controller 20 through the plurality of driving electrodes 12 in the period T3, the controller 40 of the active pen 30 determines that the protocol of the touch controller 20 is the bi-directional protocol. The active pen 30 automatically switches to bi-directional protocol during period T4.
As can be seen from fig. 4, the active pen 30 can fixedly transmit an active pen signal of a specific one-way protocol, so that the active pen 30 can detect (support) a touch controller of one-way protocol. As can be seen from FIG. 5, the active pen 30 can send active pen signals of different bi-directional protocols, so that the active pen 30 can support touch controllers of a plurality of bi-directional protocols. In short, the active pen 30 can support one-way protocol touch controllers as well as multiple two-way protocol touch controllers.
In addition, another feature of the present disclosure is that when the touch controller 20 supports at least two protocols (at least two of one unidirectional protocol and multiple bidirectional protocols), the touch controller 20 automatically switches to one of the at least two protocols. After the touch controller 20 is automatically switched to one of the at least two protocols, the active pen 30 is then adapted to automatically detect the protocol of the touch controller 20 and switch the protocol of the active pen 30 to the one of the protocols of the touch controller 20.
More specifically, the touch controller 20 automatically switches to one of the at least two protocols in response to a specific rule. The specific rules include, but are not limited to, at least one of the report rate (report rate), the pressure level (pressure level) of the pressure sensing component 38 of the active pen 30, the tilt angle, and the power saving level. For example, the touch controller 20 automatically switches to a protocol with a higher reporting rate. Alternatively, the touch controller 20 automatically switches to a protocol having a higher degree of pressure sensitivity. Alternatively, the touch controller 20 automatically switches to a protocol supporting tilt angles. Alternatively, the touch controller 20 automatically switches to a protocol with a higher power saving level.
Referring to fig. 1 to 3 and fig. 6 to 7, fig. 6 shows a timing chart of the touch controller 20 detecting that the protocol of the active pen 30 is a unidirectional protocol. FIG. 7 shows a timing diagram of the touch controller 20 detecting that the protocol of the active pen 30 is a two-way protocol.
One feature of the present disclosure is that the touch controller 20 can automatically detect whether the protocol of the active pen 30 is a one-way protocol (FIG. 6) or a two-way protocol (FIG. 7). More specifically, when the protocol of the active pen 30 is a unidirectional protocol, it means that the active pen 30 only transmits an active pen signal and does not receive a controller signal having a bidirectional protocol transmitted by the touch controller 20. When the protocol of the active pen 30 is bidirectional, the active pen 30 sends an active pen signal and receives a controller signal with bidirectional protocol sent by the active pen 30.
In fig. 6, the protocol of the active pen 30 is a unidirectional protocol, so that the controller signal with a bidirectional protocol sent by the touch controller 20 is not received. The touch controller 20 transmits a controller signal having a bi-directional protocol (e.g., bi-directional protocol N0) during the period T5, and the active pen 30 does not receive the controller signal as described above.
The touch controller 20 detects whether the transmitting portion 34 of the active pen 30 transmits an active pen signal having a unidirectional protocol or a bidirectional protocol during the period T6. Since the transmitting portion 34 of the active pen 30 does not transmit the active pen signal having the unidirectional protocol or the bidirectional protocol during the period T6, the touch controller 20 does not detect that the transmitting portion 34 of the active pen 30 transmits the active pen signal having the unidirectional protocol or the bidirectional protocol during the period T6.
The touch controller 20 transmits a controller signal having a bi-directional protocol (e.g., bi-directional protocol N1) during the period T7, and the active pen 30 does not receive the controller signal as described above.
The touch controller 20 detects whether the transmitting portion 34 of the active pen 30 transmits an active pen signal having a unidirectional protocol or a bidirectional protocol during the period T8. Since the transmitting part 34 of the active pen 30 transmits the active pen signal having the unidirectional protocol in the period T8, the touch controller 20 detects that the transmitting part 34 of the active pen 30 transmits the active pen signal having the unidirectional protocol in the period T8, and the touch controller 20 automatically switches to the unidirectional protocol in the period T8.
In fig. 7, the protocol of the active pen 30 is bi-directional, so that the transmitting portion 34 of the active pen 30 transmits an active pen signal having bi-directional protocol and the receiving portion 36 of the active pen 30 receives a controller signal having bi-directional protocol transmitted by the active pen 30.
The touch controller 20 transmits a controller signal having a bi-directional protocol (e.g., bi-directional protocol N0) during the period T9, and the receiving portion 36 of the active pen 30 receives the controller signal as described above.
The touch controller 20 detects whether the transmitting portion 34 of the active pen 30 transmits an active pen signal having a unidirectional protocol or a bidirectional protocol during the period T10. Since the bidirectional protocol N0 is not compatible with the active pen 30, the transmitting portion 34 of the active pen 30 does not transmit an active pen signal, and the touch controller 20 does not detect that the transmitting portion 34 of the active pen 30 transmits an active pen signal having a unidirectional protocol or a bidirectional protocol during the period T10.
The touch controller 20 transmits a controller signal having a bi-directional protocol (e.g., bi-directional protocol N1) during the period T11, and the receiving portion 36 of the active pen 30 receives the controller signal as described above.
The touch controller 20 detects whether the transmitting portion 34 of the active pen 30 transmits an active pen signal having a unidirectional protocol or a bidirectional protocol during the period T12. Since the bidirectional protocol N1 is not compatible with the active pen 30, the transmitting portion 34 of the active pen 30 does not transmit an active pen signal, and the touch controller 20 does not detect that the transmitting portion 34 of the active pen 30 transmits an active pen signal having a unidirectional protocol or a bidirectional protocol during the period T12.
The touch controller 20 transmits a controller signal having a bi-directional protocol (e.g., bi-directional protocol N2) during the period T13, and the receiving portion 36 of the active pen 30 receives the controller signal as described above.
The touch controller 20 detects whether the transmitting portion 34 of the active pen 30 transmits an active pen signal having a unidirectional protocol or a bidirectional protocol during the period T14. Since the bidirectional protocol N2 is compatible with the active pen 30, the transmitting portion 34 of the active pen 30 transmits an active pen signal with the bidirectional protocol N2, and the touch controller 20 detects the transmitting portion 34 of the active pen 30 to transmit an active pen signal with the bidirectional protocol during the period T14.
As can be seen from fig. 6, the touch controller 20 can detect the active pen signals of various unidirectional protocols, so that the touch controller 20 can support the active pen of various unidirectional protocols. As can be seen from fig. 7, the touch controller 20 can send active pen signals of different bi-directional protocols, so that the touch controller 20 can support active pens of multiple bi-directional protocols. In short, the touch controller 20 can support touch controllers of multiple unidirectional protocols and touch controllers of multiple bidirectional protocols.
In addition, another feature of the present disclosure is that when the touch controller 20 supports at least two protocols, the touch controller 20 automatically switches to one of the at least two protocols to connect with the active pen 30.
More specifically, the touch controller 20 automatically switches to one of the at least two protocols (at least two of a plurality of unidirectional protocols and a plurality of bidirectional protocols) in response to a specific rule. The specific rules include, but are not limited to, at least one of the click-through rate, the degree of pressure sensing by the pressure sensing element 38 of the active pen 30, the tilt angle, and the power saving degree. For example, the touch controller 20 automatically switches to a protocol with a higher reporting rate. Alternatively, the touch controller 20 automatically switches to a protocol having a higher degree of pressure sensitivity. Alternatively, the touch controller 20 automatically switches to a protocol supporting tilt angles. Alternatively, the touch controller 20 automatically switches to a protocol with a higher power saving level.
In the touch control system disclosed by the invention, the active pen and the touch controller can automatically detect the protocol of the other one and switch to the protocol of the other one. In addition, when the touch controller supports at least two bidirectional protocols, the touch controller can be automatically switched to one of the at least two bidirectional protocols.
In summary, although the present disclosure has been described with reference to the preferred embodiments, the preferred embodiments are not intended to limit the disclosure, and those skilled in the art may make various modifications and alterations without departing from the spirit and scope of the disclosure, so that the scope of the disclosure is defined by the appended claims.
