Description
Technical Field
The present disclosure relates to the field of terminal technologies, and in particular, to a touch response method and apparatus.
Background
The in-screen fingerprint technology is a technology for integrating a fingerprint identification function into a touch screen, and the in-screen fingerprint can be an optical fingerprint or an ultrasonic fingerprint. Along with the wide application of the in-screen fingerprint technology to the terminal, terminals with touch screens, such as mobile phones and tablet computers, can support the in-screen fingerprint identification function. Based on the on-screen fingerprint recognition function, the terminal may detect a touch event and respond to the touch event.
Currently, a method for a terminal to perform a touch response is as follows: when the terminal is in a standby state (a black screen state), a fingerprint unlocking icon is displayed on the screen, namely, a display area of the fingerprint unlocking icon is lightened, and other areas except the area in the screen are still in the black screen state. In the standby state, all touch sensors of the touch screen are in a state of sleeping for a period of time after working for a period of time, namely the working mode and the sleeping mode are alternately performed, and the time of the working mode and the sleeping mode is longer. When the touch screen is in a working mode (Active mode), all touch sensors of the touch screen work, and whether touch operation exists is detected; when the touch screen is in the sleep mode, all touch sensors of the touch screen do not work, and meanwhile, whether touch operation exists or not cannot be detected. In the standby state, when the touch sensor detects the touch operation on the fingerprint area where the fingerprint unlocking icon is located, the terminal responds to the touch operation and starts a fingerprint unlocking function. Based on the fingerprint unlocking function, the terminal can realize fingerprint unlocking.

and the scanning frequency of the touch sensor in the preset high power consumption mode is greater than that of the touch sensor in the preset low power consumption mode.
All the above optional technical solutions may be combined arbitrarily to form the optional embodiments of the present disclosure, and are not described herein again.
Fig. 2 is a flowchart illustrating a touch response method according to an exemplary embodiment, where the touch response method is applied to a terminal having a touch screen, as shown in fig. 2, and includes the following steps:
in step 201, in a standby state, a first touch sensor of the touch screen is controlled to operate in a first state, and a second touch sensor of the touch screen is controlled to operate in a second state, where the first touch sensor is a touch sensor corresponding to a fingerprint area of the touch screen, the second touch sensor is a touch sensor corresponding to an area other than the fingerprint area, and a scanning frequency of the touch sensor in the first state is greater than a scanning frequency of the touch sensor in the second state.
The standby state refers to a black screen state, that is, a state in which the terminal screen is locked and extinguished. Fingerprint region can realize that the fingerprint is regional in the screen of fingerprint unblock, like the effective induction zone of optics fingerprint or the effective induction zone of ultrasonic fingerprint.
In one possible implementation, the fingerprint area includes a fingerprint unlock icon displayed by the touch screen in a standby state. For example, in a standby state, the terminal may display the fingerprint unlocking icon in the fingerprint area, where the fingerprint unlocking icon is used to indicate a position of the fingerprint area on the touch screen, so that a user may perform a touch operation on the fingerprint unlocking icon to start a fingerprint unlocking function. The fingerprint unlocking icon may be a fingerprint pattern, or may be any other pattern, such as a cross, as long as the position where the user can be prompted to perform the touch operation.
Accordingly, the fingerprint area can be specifically designed by a terminal developer according to the display position and size of the fingerprint unlocking icon on the touch screen. For example, the position of the fingerprint area is designed according to the position of the fingerprint unlocking icon, and taking the example that the terminal displays the fingerprint unlocking icon in the lower area of the touch screen, the fingerprint area may be the lower area of the touch screen that includes the fingerprint unlocking icon. In addition, the terminal developer may also design the size of the fingerprint area according to the size of the fingerprint unlocking icon, for example, if the fingerprint unlocking icon is a circle with a radius of a, the fingerprint area may be a circle with a radius of b, where a and b are positive integers and b is greater than or equal to a. The embodiment of the disclosure limits the specific design of the fingerprint area.
It should be noted that the touch screen of the terminal may be composed of a touch sensor array, where the touch sensor array includes a plurality of touch sensors, and the touch sensors may be distributed at various positions of the touch screen to detect a touch operation of a user. In one possible implementation manner, the terminal developer can also design the fingerprint area according to the position of the touch sensor and the position and the size of the fingerprint unlocking icon. For example, the touch sensors at different positions may be responsible for detecting touch operations at different positions on the touch screen, and have different touch operation detection areas. Accordingly, the designated area may be composed of a detection area of the at least one touch sensor around the fingerprint unlock icon, in which case the designated area includes a complete detection area of the at least one touch sensor. In fact, the designated area may also include only a part of the detection areas of the at least one touch sensor, as long as the designated area composed of the detection areas can include the fingerprint unlock icon.
Referring to fig. 3, a schematic diagram of a fingerprint area is provided, as shown in fig. 3, with a total of 18 touch sensors, such as touch sensors 1 through 18. Each square box represents a pixel in the touch sensor array, corresponding to a touch sensor. The fingerprint pattern in fig. 3 is a fingerprint unlock icon, and the dotted line frame is a fingerprint area which is an area composed of the detection areas of the touch sensors 11, 13, 14, 15, and 17.
In the embodiment of the present disclosure, the first touch sensor corresponding to the fingerprint area is a touch sensor whose detection area and the fingerprint area have an intersection, and the second touch sensor is a touch sensor whose detection area and the fingerprint area have no intersection. When the fingerprint area is as shown in fig. 3, the first touch sensors may include touch sensors 11, 13, 14, 15, and 17, and the second touch sensors may include touch sensors 1 to 10, 12, 16, and 18.
In a possible implementation manner, the touch sensor in the first state and the touch sensor in the second state operate in a state where a preset high power consumption mode and a preset low power consumption mode are performed alternately, and an alternating interval in the first state is smaller than an alternating interval in the second state, where the alternating interval is a time interval between two adjacent times of the touch sensors operating in the preset high power consumption mode; and the scanning frequency of the touch sensor in the preset high power consumption mode is greater than that of the touch sensor in the preset low power consumption mode.
That is, in the standby state, the first touch sensor and the second touch sensor of the touch screen operate in a state where the preset high power consumption mode and the preset low power consumption mode are performed alternately, and a time interval between two adjacent times of the first touch sensor operating in the preset high power consumption mode is smaller than a time interval between two adjacent times of the second touch sensor operating in the preset high power consumption mode.
The preset high power consumption mode can be an Active mode (working mode), and the touch sensor in the Active mode has high scanning frequency, high power consumption and high response speed to touch operation; the preset low power consumption mode may be a sleep mode in which the scanning frequency of the touch sensor is low, the power consumption is low, and the response speed to the touch operation is slow. When the touch sensor works in an Active mode, the touch sensor senses whether a finger touches the touch sensor, and power consumption is generated at the same time. When the touch sensor operates in the sleep mode, power consumption is not generated basically, but finger touch is not sensed at the same time. In addition, each touch sensor generates power consumption, and the fewer touch sensors in Active mode, the less total power consumption.
Referring to fig. 4, an operating state of the first touch sensor and the second touch sensor is provided, fig. 4 (a) is a schematic diagram of a state where the first touch sensor is alternately operated and dormant, and fig. 4 (b) is a schematic diagram of a state where the second touch sensor is alternately operated and dormant, and it can be seen that in this manner, the first touch sensor and the second touch sensor are both operated for a period of time and dormant for a period of time, but the first touch sensor is dormant for a period of time shorter than the second touch sensor is dormant for a period of time. The first touch sensor is more frequently operated in the Active mode, and although the power consumption of the touch sensor in the Active mode is high, the number of the first touch sensors is smaller than that of all the touch sensors, so that the total power consumption is not large. And the touch sensor has high response speed to the touch operation in the Active mode, so the setting of the first touch sensor can ensure that the terminal can detect the touch operation of the finger of the user on the fingerprint area more timely, thereby responding to the touch operation in time. The timely response means that after the user performs a touch operation on the touch screen, the terminal can respond to the touch operation of the user within a target time length, and the target time length can be recorded in configuration parameters of the terminal and is determined by hardware conditions of the terminal.
The local Active scanning induction is performed on the fingerprint area for realizing fingerprint unlocking, and the scanning induction mode with lower frequency is used for the rest areas, so that the balance between the power consumption of the touch screen and the finger touch response can be obtained, and the problem that in the related technology, the touch operation detected by the terminal is delayed due to the fact that all touch sensors work and sleep simultaneously, and the touch operation of a user cannot be responded timely is solved.
It is understood that, in order to further reduce the power consumption of the touch screen, the terminal may further set the first state and the second state as follows: the touch sensor in the first state operates in a state where a preset high power consumption mode and a preset low power consumption mode are alternately performed, and the touch sensor in the second state operates in the preset low power consumption mode. That is, in the standby state, the first touch sensor of the touch screen operates in a state where the preset high power consumption mode and the preset low power consumption mode are alternately performed, and the second touch sensor of the touch screen operates in the preset low power consumption mode. In this way, the terminal may control the first touch sensor in the fingerprint area to be in a state of working for a period of time and sleeping for a period of time, and control the second touch sensors in other areas to work in a state of not scanning at all according to the definition of the terminal manufacturer on the unlocking scene, which is not limited in the embodiment of the present disclosure.
In step 202, when a touch operation on the fingerprint area is detected through the first touch sensor, a fingerprint unlocking function is started.
The fingerprint unlocking function can be an optical fingerprint unlocking function or an ultrasonic fingerprint unlocking function.
In the embodiment of the disclosure, the first touch sensor corresponding to the fingerprint area detects the touch operation of the fingerprint area in the first state, and once the terminal detects the touch of the finger of the user on the fingerprint area through the first touch sensor, the fingerprint unlocking function of the fingerprint area can be started in time. Taking the fingerprint area as shown in fig. 3 as an example, the first touch sensor may include touch sensors 11, 13, 14, 15, and 17, and the terminal may detect whether a finger touches the fingerprint area through the 5 touch sensors.
In one possible implementation manner, the terminal starts a fingerprint unlocking function, and the fingerprint unlocking function includes: and starting a fingerprint sensor corresponding to the fingerprint area, wherein the fingerprint sensor is used for acquiring a fingerprint image by the terminal. The fingerprint sensor may be an optical fingerprint sensor or an ultrasonic fingerprint sensor, for example, there may be a fingerprint sensor inside a touch screen of the terminal, and the position of the fingerprint sensor corresponds to the fingerprint area, for example, the fingerprint sensor may be at the position of the touch sensor 14 shown in fig. 3. In a standby state, the fingerprint sensor may not operate, and when the terminal detects a touch operation to the fingerprint area through the first touch sensor, the fingerprint sensor may be controlled to operate, for example, the terminal may switch the fingerprint sensor from a sleep mode to an Active mode.
In step 203, fingerprint unlocking is realized based on the fingerprint unlocking function.
In the embodiment of the disclosure, the terminal can provide a fingerprint unlocking function, and based on the fingerprint unlocking function, a user can perform fingerprint unlocking operation on the terminal.
In a possible implementation manner, the terminal based on the fingerprint unlocking function may implement a fingerprint unlocking process, including: after the terminal starts the fingerprint unlocking function, in the process that a user touches the fingerprint area, the terminal can detect the finger of the user through the optical fingerprint sensor corresponding to the fingerprint area to obtain a reflected optical signal, and the reflected optical signal is converted into an electric signal and then is converted into a fingerprint image. The reflected light signal is the light signal reflected by the lines on the surface of the finger print of the user. When the fingerprint image is matched with a fingerprint image pre-stored by the terminal, namely the fingerprint is correct, the terminal can unlock and display a normal operation interface, and if the fingerprint image is not matched with the fingerprint image pre-stored by the terminal, namely the fingerprint is wrong, the terminal can unlock the screen. The touch operation of a user is timely detected through the first touch sensor in the fingerprint area, so that the terminal can timely respond to the touch operation, the fingerprint unlocking is further realized, and the delay problem of the fingerprint unlocking is avoided.
For example, when the user uses the fingerprint unlocking function for the first time, the terminal performs touch operation on a fingerprint area of the terminal according to a fingerprint entry guide provided by the terminal, and can acquire and store the fingerprint image of the user, so that entry of a fingerprint is completed.
It should be noted that, the foregoing possible implementation manner is described by taking a fingerprint unlocking function as an example of an optical fingerprint unlocking function, and in fact, the fingerprint unlocking function may also be an ultrasonic fingerprint unlocking function, and accordingly, in a possible implementation manner, the process of implementing fingerprint unlocking by the terminal based on the fingerprint unlocking function may include: after the terminal starts a fingerprint unlocking function, the ultrasonic fingerprint sensor corresponding to the fingerprint area can transmit ultrasonic signals and receive the ultrasonic signals reflected back by the fingers of a user, then fingerprint information of the user is obtained according to the transmitted ultrasonic signals and the received reflected ultrasonic signals, and when the obtained fingerprint information is compared with preset fingerprint information to be consistent, the terminal can be unlocked.
In the embodiment of the disclosure, the touch operation is detected more frequently by controlling the touch sensor in the fingerprint area, and the touch operation of the finger of the user on the fingerprint area can be detected in time, so that the touch operation is responded in time, the fingerprint unlocking function is started, the problem that the touch response is not timely due to the delay of the terminal in detecting the touch operation is avoided, the fingerprint unlocking function is ensured to be started in time, and the fingerprint unlocking is faster.
In addition, because the number of the touch sensors in the fingerprint area is small, even if the part of the sensors work in a high power consumption mode more frequently, the total power consumption of the touch screen is not large, and the response speed of the touch sensors to touch operation in the high power consumption mode is high, so that the touch operation can be detected in time, balance can be obtained between the power consumption of the touch screen and the touch response, and the fast touch response can be realized with lower power consumption.
