Connected to the second device indirectly.

FIG. 1 is a functional block diagram of an electronic device according to an exemplary embodiment of the invention. Referring to FIG. 1 , the electronic device 100 includes a touch panel or a touch pad 110 , a driving unit 120 , a processing unit 130 , and an interface circuit 160 . In the exemplary embodiment, the electronic device 100 can be any information product, such as a mobile phone, a personal digital assistant (PDA), a smart phone, an e-book, a game console, a tablet computer, or a personal computer. The invention is not limited thereto.

The touch panel 110 is used as a user input operation command. For example, the touch panel 110 can detect an input command of the user to cause the electronic device 100 to perform a corresponding action. In the present exemplary embodiment, the touch panel 110 can be a resistive touch panel, a capacitive touch panel, an optical touch panel, an infrared touch panel, or an electromagnetic induction touch panel. The present invention does not apply to the touch panel 110. The type is limited.

The driving unit 120 is coupled to the touch panel 110 and the interface circuit 160. In this embodiment, the driving unit 120 may be a panel driving circuit, a panel driving chip, or a touch panel controller, etc., and the invention is not limited thereto. The driving unit 120 drives the touch panel 110 in a working configuration to read the touch coordinates on the touch panel 110. The working configuration includes a scanning frequency, a threshold of a sensing threshold, or a value of a repeated acknowledgment number. For example, the driving unit 120 continuously scans/drives the touch panel 110 at a specific scanning frequency according to the working configuration, so that when the user touches the touch panel 110, the driving unit 120 The touch signal corresponding to the touch position on the touch panel 110 can be read instantly, and the touch signal is converted into information related to the touch position, such as a touch coordinate. For another example, the driving unit 120 filters the touch signal of the touch panel 110 according to the sensing threshold value of the working configuration, and converts the touch signal larger than the sensing threshold value into a touch coordinate.

For another example, the driving unit 120 filters the pseudo touch signal of the touch panel 110 according to the repeated confirmation times value of the working configuration, and converts the true touch signal into a touch coordinate. Assuming that the "repeated confirmation number value" is "4 times", when the touch signal of a touch position of the touch panel 110 is greater than the sensing threshold value, the driving unit 120 repeatedly confirms the touch signal of the same touch position four times in succession. Is it greater than the sensing threshold? If the touch signal of the same touch position is greater than the sense threshold value, the driving unit 120 can determine that the touch signal of the touch position should be the true touch caused by the physical object touching the touch panel 110. Touch the signal, not the pseudo-touch signal caused by the noise. therefore, After repeating the confirmation four times in succession, the driving unit 120 can convert the touch signal into a touch coordinate.

The processing unit 130 is coupled to the driving unit 120 and the interface circuit 160. In the present exemplary embodiment, the processing unit 130 may be a central processing unit, a keyboard controller, a micro-controller, or a control chipset. The invention is not limited thereto. After the driving unit 120 converts the touch signal of the touch panel 110 into a touch coordinate, the touch coordinates are transmitted to the processing unit 130. Therefore, the processing unit 130 can receive a user input operation instruction through the driving unit 120 and the touch panel 110.

Peripheral component 170 includes a charger 172, a High-Definition Multimedia Interface (HDMI) component 174, or other peripheral components. The peripheral component 170 is coupled to the electronic device 100 through a corresponding interface circuit 160. For example, the charger 172 can be connected to the electronic device 100 through a corresponding Universal Serial Bus (USB) interface circuit 162 to provide power required for the operation and charging of the electronic device 100. For another example, the electronic device 100 can transmit the HDMI image data to the HDMI component 174 (eg, a television or a monitor) through the corresponding HDMI interface circuit 164. In other embodiments, the peripheral component 170 can also be a mouse, keyboard, or other peripheral device or the like.

When the peripheral component 170 is connected to the interface circuit 160 of the electronic device 100, or the peripheral component 170 connected to the electronic device 100 is enabled, the interface circuit 160 notifies the driving unit 120 and the processing unit 130 of the characteristic information of the peripheral component 170. Therefore, the driving unit 120 and the processing unit 130 The characteristic information of the peripheral component 170, such as the brand, model, device category or other information, can be obtained through polling or interrupting through the corresponding interface circuit 160. For example, the driving unit 120 and the processing unit 130 can obtain the brand, model or other information of the charger 172 through the USB interface circuit 162. In other embodiments, the characteristic information of the peripheral component 170 is related to the component characteristics of the peripheral component 170 itself, such as the operating frequency of the peripheral component 170.

In other embodiments, the characteristic information includes a flag signal. For example, the first flag signal is true (true) indicates that the charger 172 is connected to the USB interface circuit 162 (or the charger 172 is enabled), and the first flag signal is false (false) for the charger. 172 is not connected to the USB interface circuit 162 (or the charger 172 is disabled), and the second flag signal is true to indicate that the HDMI component 174 is connected to the HDMI interface circuit 164 (or the HDMI component 174 is enabled) to The second flag signal is false indicating that the HDMI component 174 is not connected to the HDMI interface circuit 164 (or the HDMI component 174 is disabled). Therefore, the driving unit 120 and the processing unit 130 can distinguish, from the characteristic information of the peripheral component 170 provided by the interface circuit 160, whether the peripheral component 170 is connected to the electronic device 100, and the device category connected to the peripheral component 170 of the electronic device 100 (for example, USB component class, HDMI component class, etc.).

In the present embodiment, the working configuration used by the driving unit 120 is appropriately dynamically adjusted according to the operating state of the electronic device 100. When the peripheral component 170 is coupled or electrically connected to the interface circuit 160 of the electronic device 100, or is enabled by the peripheral component 170 connected to the electronic device 100, for example, charging When the electrical device 172 or the HDMI component 174 is electrically connected to the interface circuit 160 of the electronic device 100, the driving unit 120 can know the characteristic information of the peripheral component 170, and according to the characteristic information of the peripheral component 170, from a plurality of configuration parameter sets (configuration parameter A set of configuration parameters corresponding to the peripheral component 170 is found in set), and the working configuration of the driving unit 120 is adjusted according to the found configuration parameter set. The configuration parameter set includes an operating frequency setting, a sensing threshold value, a repeated confirmation number value, or other operating parameters. In the embodiment, when the electronic device 100 is shipped from the factory, the plurality of configuration parameter sets are already recorded in the driving unit 120 of the electronic device 100, but the invention is not limited thereto. In other embodiments, when the electronic device 100 is shipped from the factory, the content of the plurality of configuration parameter sets may be blank, and the content of the configuration parameter set is determined by the user.

When the peripheral component 170 is coupled or electrically connected to the interface circuit 160 of the electronic device 100, or the peripheral component 170 connected to the electronic device 100 is enabled, the driving unit 120 can find a corresponding information according to the characteristic information of the peripheral component 170. A set of configuration parameters of the peripheral component 170 and an operational configuration of the drive unit 120 are adjusted according to the set of configuration parameters. Therefore, the driving unit 120 can dynamically adopt an optimized working configuration when scanning/driving the touch panel 110 to reduce interference noise from the peripheral components 170. For example, the driving unit 120 determines the scanning frequency of the driving unit 120 according to the operating frequency setting of the configuration parameter set (avoiding the scanning frequency interfered by the peripheral component 170), and then drives the touch panel 110 at the scanning frequency to reduce the Interference noise of peripheral component 170.

In an embodiment of the invention, the drive unit 120 has a memory for recording the operational configuration of the touchpad 110. The driving unit 120 determines its operation mode on the touch panel 110 according to the working configuration, such as a coordinate algorithm, a sensing threshold, a scanning frequency, and the like. In this embodiment, the working configuration of the memory record of the drive unit 120 includes an initial default configuration and a current working configuration. In the initial state, the current working configuration is set to the initial default configuration, so the driving unit 120 determines its working configuration for driving the touch panel 110 according to the initial default configuration.

When the peripheral component 170 is connected to the interface circuit 160 of the electronic device 100, or the peripheral component 170 connected to the electronic device 100 is enabled, the processing unit 130 searches for a corresponding correspondence from a plurality of configuration parameter sets according to the characteristic information of the peripheral component 170. A set of configuration parameters of the peripheral component 170 is then used to determine whether to change the current operational configuration of the drive unit 120 based on the set of configuration parameters corresponding to the peripheral component 170. After the current working configuration of the driving unit 120 is changed, the driving unit 120 changes the operation mode for driving the touch panel 110 (for example, changing the scanning frequency) according to the new current working configuration.

The driving unit 120 determines the scanning frequency of the driving unit 120 according to the "operating frequency setting" of the configuration parameter set corresponding to the peripheral component 170, and drives the touch panel 110 at the scanning frequency. When the scanning frequency of the touch panel 110 of the driving unit 120 collides with the peripheral component 170, the peripheral component 170 will affect the performance of the touch panel 110. In this embodiment, when the scanning frequency of the touch panel 110 conflicts with the peripheral component 170, the driving unit 120 changes the scanning frequency of the touch panel 110, and The "operating frequency setting" of the configuration parameter set corresponding to the peripheral component 170 should be corrected to avoid the frequency range of the conflicting peripheral component 170.

In this embodiment, when the scanning frequency of the touch panel 110 conflicts with the peripheral component 170 by the driving unit 120, the driving unit 120 may change the scanning frequency by using a “frequency hopping operation” to find that it is not interfered by the peripheral component 170. frequency band. After finding a frequency band that is not interfered by the peripheral component 170, the driving unit 120 changes the current working configuration to change the scanning frequency of the touch panel 110, and correspondingly corrects the "operating frequency setting" corresponding to the configuration parameter set of the peripheral component 170. .

In this embodiment, the working configuration of the memory record of the driving unit 120 includes an initial default configuration and a current working configuration. The driving unit 120 determines the driving operation mode of the touch panel 110 according to the current working configuration. When the peripheral component 170 is disabled or removed, the drive unit 120 can restore the current working configuration of the internal memory of the drive unit 120 to the same content as the initial default configuration. In another embodiment, when the peripheral component 170 is disabled or removed, the drive unit 120 returns the current working configuration to the initial default configuration in accordance with an initial set of parameters pre-recorded in the drive unit 120.

If the characteristic information of a new peripheral component (eg, HDMI component 174) is not previously registered in the drive unit 120 during the process of the drive unit 120 looking up the configuration parameter set, the drive unit 120 creates a new configuration parameter. And collecting the relationship between the characteristic information of the new peripheral component and the new configuration parameter set. The initial content of the new configuration parameter set may be the same as the content of the "initial parameter set", and/or may be required by the user Find the content of the new configuration parameter set. In other embodiments, the initial content of the new configuration parameter set may be the same as the content of the configuration parameter set of the same type of peripheral component. For example, suppose the configuration parameter set A1 is applied to the charger B1. When the drive unit finds that the characteristic information of the new charger B2 is not previously registered in the drive unit, the drive unit creates a new configuration parameter set A2, and the new group The initial content of the state parameter set A2 is set to be the same as the content of the configuration parameter set A1 of the peripheral component B1 of the same type.

The driving unit 120 can dynamically adjust the content of the new configuration parameter set according to the characteristic information of the new peripheral component. For example, when the scanning frequency of the touch panel 110 of the driving unit 120 is disturbed by the new peripheral component 170, the driving unit 120 may use a frequency hopping operation to change the scanning frequency of the touch panel 110 by the driving unit 120 to find no A frequency band that is interfered by this new peripheral component 170. After finding a frequency band that is not interfered by the peripheral component 170 in a frequency hopping operation, the drive unit 120 logs the frequency band that is not interfered by the peripheral component 170 to the new configuration parameter set. At this point, the drive unit 120 has "knowed" the new peripheral component 170. When the next peripheral component 170 (eg, HDMI component 174) is enabled or reconnected to the electronic device 100 again, the driving unit 120 can quickly determine whether to change the scanning frequency of the driving unit 120 without conventional time-consuming Frequency hopping operation.

2 is a flow chart showing a method of operating a touch panel of an electronic device according to an embodiment of the invention. Referring to FIG. 1 and FIG. 2 simultaneously, in step S210, at least one interface circuit 160 detects whether at least one peripheral component 170 is connected to the interface circuit 160, or whether the peripheral component 170 connected to the interface circuit 160 is enabled ( Enable). Wherein the peripheral component The 170 is connected to the electronic device 100 through the interface circuit 160. In step S220, the driving unit 120 drives the touch panel 110 in a working configuration to read the touch coordinates of the touch panel 110. The sequence of steps S210 and S220 shown in FIG. 2 is merely an example. In another embodiment, after step S220 is completed, step S210 is performed. In other embodiments, step S210 and step S220 can be performed simultaneously.

In the initial state after the power-on, the operation used by the drive unit 120 in step S220 is configured as an initial default configuration. For example, according to the factory setting, the initial scanning frequency of the driving unit 120 for driving the touch panel 110 is 300 kHz (kilohertz).

In step S230, the driving unit 120 determines whether the peripheral component 170 of the electronic device 100 is enabled or connected to the interface circuit 160 of the electronic device 100. For example, the driving unit 120 determines whether the peripheral component 170 is enabled or connected to the electronic device 100 according to the reward signal of the interface circuit 160. When the peripheral element 170 is enabled or connected to the interface circuit 160, the drive unit 120 performs step S240, otherwise returns to step S210 and/or step S220.

The driving unit 120 obtains characteristic information of the peripheral component 170 through the interface circuit 160 in step S230. The driving unit 120 searches for a configuration parameter set corresponding to the peripheral component 170 from a plurality of configuration parameter sets according to the characteristic information of the peripheral component 170 in step S240. After the driving unit 120 obtains the configuration parameter set corresponding to the peripheral component 170, the driving unit 120 proceeds to step S250 to adjust the driving unit according to the configuration parameter set. 120 working configuration. Then, the drive unit 120 returns to step S210 and/or step S220.

For example, Table 1 illustrates the relationship between the characteristic information of the peripheral component 170 and the configuration parameter set. Here, only the charger 172 and the HDMI component 174 are taken as an illustrative example, and those skilled in the art can refer to more peripheral components with reference to the teachings of the present embodiment. When both the charger 172 and the HDMI component 174 are disabled or removed, the operating configuration of the drive unit 120 is restored by the drive unit 120 to the initial default configuration in accordance with the initial set of parameters.

Referring to Table 1 and FIG. 1, when the charger 172 is disabled or removed, and the HDMI component 174 is enabled or connected to the interface circuit 160, the driving unit 120 finds out the applicable information according to the characteristic information of the peripheral components. The configuration parameter set A of the HDMI component 174 is adjusted, and the operational configuration of the drive unit 120 is adjusted according to the configuration parameter set A. Taking the scanning frequency in the working configuration as an example, assuming that the operating frequency of the HDMI component 174 is 305 kHz, which is very close to the operating frequency setting value 300 kHz of the touch panel 110 by the driving unit 120 in the initial default configuration, the HDMI component 174 Working frequency The operation of the driving unit 120 in the initial default configuration will be disturbed, and a large amount of noise is generated in the sensing result of the touch panel 110, thereby affecting the sensing performance of the touch panel 110. Therefore, after the drive unit 120 applies the configuration parameter set A suitable for the HDMI component 174, the drive unit 120 changes the scan frequency according to the operating frequency setting of the configuration parameter set A, for example, changes the scan frequency to 350 kHz. Then, the driving unit 120 drives the touch panel 110 to use the changed scanning frequency to read the touch coordinates of the user on the touch panel 110.

Referring to Table 1 and FIG. 1, when the HDMI component 174 is disabled or removed, and the charger 172 is enabled or connected to the interface circuit 160, the driving unit 120 finds out the applicable information according to the characteristic information of the peripheral components. The configuration parameter set B of the charger 172 is used, and the working configuration of the driving unit 120 is adjusted according to the configuration parameter set B. Taking the scanning frequency in the working configuration as an example, assuming that the operating frequency of the charger 172 is 355 kHz, which is very close to the current scanning frequency of the touch panel 110 of the driving unit 120, the operating frequency of the charger 172 will interfere with the driving. The operation of the unit 120 affects the sensing performance of the touch panel 110. Therefore, after the drive unit 120 applies the configuration parameter set B suitable for the charger 172, the drive unit 120 changes the scan frequency according to the operating frequency setting of the configuration parameter set B, for example, changes the scan frequency to 300 kHz. Then, the driving unit 120 drives the touch panel 110 to use the changed scanning frequency to read the touch coordinates of the user on the touch panel 110.

Referring to Table 1 and FIG. 1, when both the charger 172 and the HDMI component 174 are enabled or both are connected to the interface circuit 160, the driving unit is 120 finds the configuration parameter set C applicable to the charger 172 and the HDMI component 174 according to the characteristic information of the peripheral components, and adjusts the working configuration of the driving unit 120 according to the configuration parameter set C. Taking the scanning frequency in the working configuration as an example, assuming that the operating frequency of the charger 172 is 355 kHz and the operating frequency of the HDMI component 174 is 305 kHz, which is very close to the current scanning frequency of the touch panel 110 of the touch panel 110, the charging is performed. The operating frequency of the 172 and/or HDMI component 174 will interfere with the operation of the drive unit 120 and affect the sensing performance of the touchpad 110. Therefore, after the drive unit 120 applies the configuration parameter set C suitable for the charger 172, the drive unit 120 changes the scan frequency according to the operating frequency setting of the configuration parameter set C, for example, changes the scan frequency to 400 kHz. Then, the driving unit 120 drives the touch panel 110 to use the changed scanning frequency to read the touch coordinates of the user on the touch panel 110.

Accordingly, the driving circuit 120 can quickly and easily switch between different operating configurations depending on the connection state (enable state) of the peripheral component 170 to improve the noise interference caused by the peripheral device 170.

In the embodiment of the present invention, the driving unit 120 searches for a configuration parameter set corresponding to the peripheral component 170 according to the characteristic information of the peripheral component 170, and adjusts the driving unit 120 according to the configuration parameter set. Work configuration. Accordingly, the electronic device 100 can dynamically switch between different operating configurations depending on the connection state (enable state) of the peripheral component 170. Therefore, the electronic device 100 can improve the performance of the touch panel 110.
