and S701, generating a periodic interrupt event by an IC panel of the terminal equipment.

Illustratively, the terminal device is deployed with a REE system and a TEE system. Among them, the REE system may also be referred to as a non-secure world, and the TEE system may also be referred to as a secure world. Operating an operating system closely related to a user in the REE system; and operating the technology for ensuring the system safety in the TEE system. The non-secure world does not mean that the operating system or software running in the REE system is malicious, but rather that the REE system is less secure than the TEE system.

Fig. 8 is a first software structure diagram of a touch processing method according to an embodiment of the present application, and as shown in fig. 8, a first Touch Panel (TP) driving unit and a User Interface (UI) module are deployed in an REE system of a terminal device; a plurality of Applications (APP) run in the REE system of the terminal device. A second TP driving unit and a Trusted User Interface (TUI) module are deployed in a TEE system of the terminal equipment; a plurality of Trusted Application (TA) modules are run in the TEE system of the terminal device.

The terminal device has a screen (i.e., a terminal device screen); for example, the terminal device screen is a capacitive touch screen. An IC panel is arranged below a screen of the terminal equipment, and the IC panel is used for generating periodic interrupt events. In the present embodiment, the IC unit for calculating coordinate information of touch operation is removed; but rather employs the IC panel to automatically generate periodic interrupt events.

The IC panel of the terminal device automatically generates periodic interrupt events, wherein the frequency of the periodic interrupt events is 60 Hertz (HZ) or 90 HZ. Therefore, the user does not need to actively touch the screen of the terminal device to generate the interrupt event, but the IC panel of the terminal device automatically generates the periodic interrupt event.

S702, the terminal device receives a periodic interrupt event sent by the IC panel based on a first TP driving unit of the REE system.

Exemplarily, in the present embodiment, in order to save IC units, IC units for a user to calculate coordinate information of touch operations are removed, so that an IC panel of a terminal device screen does not have a capability of calculating coordinate information. The IC panel of the terminal device screen transmits the periodic interrupt event to the first TP driving unit of the REE system of the terminal device.

And S703, the terminal device sends a notification message to a second TP driving unit of the TEE system of the terminal device based on the first TP driving unit of the REE system, wherein the notification message is used for indicating to read the original data corresponding to the periodic interrupt event.

Exemplarily, fig. 9 is a schematic trigger diagram of a touch processing method according to an embodiment of the present application, and as shown in fig. 9, in step S901, when an interface displayed on a screen of a terminal device is an interface with a high requirement on security, a TA module of a TEE system in the terminal device invokes a TUI module of the TEE system. Step S902, a TA module of a TEE system in the terminal equipment sends first indication information to a TUI module of the TEE system, wherein the first indication information represents that the terminal equipment calls a safety interface, namely the first indication information represents that the TUI module of the TEE system is called. Step S903, the TUI module of the TEE system in the terminal equipment sends first indication information to a second TP driving unit of the TEE system, and the first indication information represents that the terminal equipment has started up a safety interface. Step S904, the second TP driver unit in the TEE system in the terminal device sends the first indication information to the first TP driver unit of the REE system, and the first indication information represents that the terminal device has invoked the security interface. Wherein step S701 is executed after each step shown in fig. 9.

According to the above process, both the REE system and the TEE system know that the terminal device has invoked the security interface, so that after step S702, in order to ensure the security of the coordinate calculation, the first TP driving unit of the REE system of the terminal device does not acquire the original data corresponding to the periodic interrupt event, and the first TP driving unit of the REE system does not process the coordinate information. In order to ensure the safety of coordinate calculation, the calculation processing of the coordinate information is completed in a TEE system of the terminal equipment.

The terminal equipment sends a notification message to a second TP driving unit of the TEE system according to the received periodic interrupt event based on a first TP driving unit of the REE system, further informs the second TP driving unit that an IC panel of a terminal equipment screen automatically generates the periodic interrupt event, and informs the second TP driving unit that original data corresponding to the periodic interrupt event needs to be read.

Illustratively, the IC panel of the terminal device screen transmits the raw data to the second TP driving unit of the TEE system in response to the read instruction. In this step, since the security of the data needs to be guaranteed, the IC panel of the terminal device screen does not transmit the original data to the REE system, but directly transmits the original data to the second TP driving unit of the TEE system.

Wherein the raw data includes a volume value.

S706, the terminal device processes the original data based on a second TP driving unit of the TEE system to obtain coordinate information; wherein, a THP (touch screen host processing) algorithm library is deployed in the second TP drive unit, and the THP algorithm library includes at least one THP algorithm.

Exemplarily, a THP algorithm library is deployed in a second TP driver unit of the TEE system; the THP algorithm library comprises at least one THP algorithm; and the THP algorithm in the THP algorithm library is used for calculating and processing the original data to obtain the coordinate information.

Therefore, the second TP driving unit of the TEE system of the terminal device adopts any algorithm in the THP algorithm library to calculate and process the acquired capacity value to obtain coordinate information.

The method comprises the steps that an IC panel automatically generates a periodic interrupt event, and if touch operation occurs on a screen of the terminal equipment, original data acquired by a second TP driving unit of a TEE system of the terminal equipment are not null values; the second TP driving unit of the TEE system of the terminal equipment can adopt any algorithm in the THP algorithm library to calculate and process the acquired capacity value to obtain coordinate information; the coordinate information represents coordinate data corresponding to the touch operation. If the touch operation does not occur on the screen of the terminal equipment, the original data acquired by a second TP driving unit of a TEE system of the terminal equipment is a null value; the second TP driving unit of the TEE system of the terminal device may use any algorithm in the THP algorithm library to perform calculation processing on the obtained volume value, and may not obtain the coordinate information, or the second TP driving unit of the TEE system of the terminal device may not perform calculation processing on the obtained null value.

And S707, the terminal equipment feeds the coordinate information back to a TUI module of the TEE system based on a second TP driving unit of the TEE system.

Exemplarily, after obtaining the coordinate information corresponding to the periodic interrupt event, the TEE system needs to respond to a response result corresponding to the coordinate information. Further, the second TP driving unit of the TEE system of the terminal device transmits the coordinate information to the TUI module of the TEE system.

And S708, the terminal equipment determines a response event result corresponding to the coordinate information based on a TUI module of the TEE system.

Illustratively, the TUI module of the TEE system of the terminal device may determine the corresponding response event result from the coordinate information.
