Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The embodiment of the invention provides a mutual-capacitance touch screen-based awakening method, as shown in fig. 1, the method comprises the following steps:
101. and detecting whether a touch signal exists in a preset area in the mutual capacitance type touch screen.
The preset area comprises at least one awakening point position, and the awakening point position is used for receiving a touch signal for awakening the mutual capacitance type touch screen.
Generally, a projected capacitive screen can be classified into a mutual capacitive touch screen and a mutual capacitive touch screen. For the mutual capacitance touch screen of the embodiment of the invention, the structure is that a transparent conductive material named ITO is used for manufacturing a transverse electrode array and a longitudinal electrode array on the surface of glass, and two groups of electrodes are coupled at the crossed position to form a capacitor, namely the two groups of transverse electrodes and the longitudinal electrodes respectively form two poles of the capacitor. When a finger touches the capacitive screen, the coupling between the two electrodes near the touch point is affected, thereby changing the capacitance between the two electrodes. When the touch screen detects the mutual capacitance, the transverse electrodes sequentially send out excitation signals, and the longitudinal electrodes simultaneously receive the signals, so that the capacitance value of the intersection point of the transverse electrodes and the longitudinal electrodes, namely the capacitance value of the two-dimensional plane of the whole touch screen can be obtained. Usually, the capacitance value after touch is reduced, so the coordinate of each touch point can be calculated according to the two-dimensional capacitance variation data of the touch screen. Therefore, even if a plurality of touch points exist on the mutual capacitance touch screen, the real coordinates of each touch point can be calculated. Therefore, the touch screen can support multi-point touch based on the characteristics of the mutual capacitance type touch screen in the process of scanning the touch signals.
Based on the characteristics of the mutual capacitance type touch screen, in the embodiment of the present invention, in order to solve the problem of large power consumption of the touch screen in the wake-up process, in this step, whether a touch signal exists in a preset area in the mutual capacitance type touch screen may be determined by detecting the preset area, where the preset area includes at least one position for receiving the touch signal for waking up the mutual capacitance type touch screen, that is, a wake-up point position. It should be noted that, in the embodiment of the present invention, the number of the wake-up points in the preset area and the set position may be selected according to actual needs, which is not specifically limited herein, for example, one or more positions may be randomly selected in the screen as the wake-up points in the preset area, or a position where the user is used for touching is set as the forehead wake-up points in the preset area according to an operation habit of the user.
Based on the method in this step, according to the detection result in the mutual capacitance type touch screen, there are two situations, when it is detected that a touch signal exists in the wake-up point location of the preset area, step 102 is executed, and when it is not detected that a touch signal exists in the wake-up point location of the preset area, step 103 is executed.
102. And awakening the mutual-capacitance touch screen to a working state.
After the preset area is detected in step 101, when it is determined that a touch signal exists, it indicates that the user touches the preset area and needs to wake up the mutual-capacitive touch screen. In this regard, the mutual capacitance touch screen may be controlled to switch to a working state according to the method described in this step, so as to wake up the touch screen.
In addition, in the embodiment of the invention, before the mutual-capacitance touch screen is awakened, prompt information can be output to confirm whether the mutual-capacitance touch screen needs to be awakened or not, so that the condition of mistaken awakening caused by mistaken contact of the awakening point in the preset area by a user can be ensured, the influence of the mistaken awakening on the awakening accuracy of the mutual-capacitance touch screen is avoided, and the influence of the mistaken awakening on the power consumption of the mutual-capacitance touch screen can be reduced.
103. And controlling the mutual capacitance type touch screen to be in a preset standby state.
In this embodiment of the present invention, after the preset area is detected in step 101, when a touch signal is not detected in the preset area, it indicates that the user does not perform a wake-up operation on the mutual capacitance type touch screen, so that the mutual capacitance type touch screen does not need to be woken up, and the mutual capacitance type touch screen can be controlled to a preset standby state, where the preset standby state is a state where other areas except the preset area in the mutual capacitance type touch screen are all closed. Therefore, when the user does not perform touch awakening on the mutual-capacitance touch screen, the touch signal is only detected in the middle preset area of the mutual-capacitance touch screen, so that other areas do not need to be detected or scanned, power consumption of signal detection in other areas outside the preset area is reduced, and power consumption in the awakening process of the mutual-capacitance touch screen in the embodiment of the invention can be reduced on the whole.
In addition, in this step, when the touch signal is not detected in the wake-up point in the preset region in the above step 101, a preset time duration may be further set, and when it is determined that the touch signal is not detected in the preset time duration, the mutual capacitance touch screen is controlled to the preset standby state. Specifically, the setting of the preset duration may be selected according to actual needs, for example: for 3 minutes. And is not particularly limited herein.
Compared with the prior art that when the mutual capacitance type touch screen waits for awakening and the whole screen is detected by touch signals, the awakening method based on the mutual capacitance type touch screen provided by the embodiment of the invention can detect whether the touch signals exist in the awakening point positions of the preset area in the mutual capacitance type touch screen, and if the touch signals exist, awakens the mutual capacitance type touch screen to the working state. Otherwise, the mutual capacitance type touch screen is controlled to be in a preset standby state, wherein the preset standby state is a state that other areas except the preset area in the mutual capacitance type touch screen are closed, so that the mutual capacitance type touch screen can be woken up when a touch signal exists in a wakening point position in the preset area, the screen can be wakened up in time, and when a user does not perform wakening operation, the area outside the preset area in the mutual capacitance type touch screen is in a closed state, so that the power consumption of the mutual capacitance type touch screen can be reduced, the problem that the power consumption is large due to the fact that the touch signal is detected on the whole screen in the process that the mutual capacitance type touch screen waits for wakening up in the prior art is solved, and the power consumption of the wakening process of the mutual capacitance type touch screen is reduced on the whole. In addition, other areas of the screen except the preset area in the preset standby state are closed, so that the problem of mistaken awakening caused by false triggering can be avoided, and the condition of power consumption waste in the awakening process of the mutual-capacitance touch screen is further reduced.
To be described in more detail below, an embodiment of the present invention provides another wake-up method based on a mutual capacitance touch screen, specifically as shown in fig. 2, where the method includes:
201. and setting a wake-up point position in a preset area in the mutual capacitance type touch screen.
In the method according to the embodiment of the present invention, the step may specifically be:
firstly, when the mutual capacitance type touch screen is in an initial standby state, acquiring a touch position of the mutual capacitance type touch screen, where the touch position receives a touch signal, the initial standby state is a state where the mutual capacitance type touch screen is in a first scanning frequency, and the first scanning frequency is less than a second scanning frequency of the mutual capacitance type touch screen in a working state. It should be noted that, in the method described in this step, the initial standby state may actually be understood as a state lower than the operating state, where the touch screen automatically enters when no touch is detected for a short time, and since no touch operation is detected for a short time, it may be understood that the user temporarily does not control the touch screen, so that the scanning frequency of the screen in this state may be lower than the scanning frequency in the operating state.
Then, when the occurrence frequency of the touch position is determined to exceed a preset threshold value, the touch position is set as a wake-up point in the preset area. Therefore, when the mutual-capacitance touch screen is in an initial standby state, the function of the preset area can be set according to the operation habit of the user, and therefore the user can conveniently perform subsequent awakening operation.
In addition, when the user wakes up the mutual capacitive touch screen, there may be a case where the user wakes up the touch screen by touching a plurality of positions during the wake-up operation based on the position of the touch screen, the habit of the user, and the like. Therefore, in this step, when it is determined that the number of occurrences of the touch position exceeds a preset threshold, the touch position is set as a wake-up point in the preset area, which may be specifically: and if the occurrence times of a plurality of different touch positions exceed a preset threshold value, respectively setting the different touch positions as different wake-up point positions in a preset area.
Therefore, the awakening point position of the preset area is set in the mutual-capacitance touch screen, so that the awakening operation can be ensured to be carried out through the awakening point position in the set preset area when the touch screen is awakened, and the power consumption of other areas outside the preset area is reduced integrally when the mutual-capacitance touch screen is awakened, and support is provided. In addition, when the mutual capacitance type touch screen is in an initial standby state, the touch position of the mutual capacitance type touch screen, which receives the touch signal, is determined, and when the occurrence frequency of the touch position is determined to exceed a preset threshold value, the touch position is set as the awakening point position of the preset area, so that the function of determining the awakening point position in the preset area by the operation habit of the user can be ensured, and the awakening operation of a subsequent user is facilitated. Meanwhile, if the occurrence frequency of a plurality of different touch positions exceeds a preset threshold value, the plurality of different touch positions are set as a plurality of different wake-up point positions in a preset area, so that a user can further ensure that the user can wake up the device from the plurality of wake-up point positions in the preset area, and then the mode of waking up the mutual-capacitance touch screen is simpler and more flexible.
202. And detecting whether a touch signal exists in a preset area in the mutual capacitance type touch screen.
After the wake-up point location for waking up the preset area of the touch screen is set in the mutual capacitive touch screen in the aforementioned step 201, in this step, detection may be performed according to the set wake-up point location to determine whether a touch signal exists in the wake-up point location set in the preset area. Specifically, the preset area includes at least one wake-up point, where the wake-up point is a position for receiving a touch signal for waking up the mutual capacitance touch screen.
In the process of waking up the mutual capacitive touch screen, a plurality of different wake-up points may be touched to wake up the touch screen, and therefore, based on different user needs and habits, in this step, corresponding wake-up conditions may be selected according to actual needs of a user, where the wake-up conditions may be understood as setting a corresponding wake-up function based on a combination of different wake-up points when a plurality of different wake-up points are set in a preset region in the mutual capacitive touch screen, and when a touch signal corresponding to a plurality of wake-up points in the touch screen is detected at the same time, determining whether a combination of touch signals corresponding to the currently existing wake-up points is used to wake up the mutual capacitive touch screen according to the preset wake-up conditions. From this, can provide the function of multiple touch screen based on mutual capacitance formula touch-sensitive screen, based on mutual capacitance formula touch-sensitive screen's touch signal's detection characteristics, when being provided with a plurality of positions of awakening up in the predetermined area, this step can specifically be: and detecting whether touch signals existing in a plurality of awakening point positions in the preset area accord with a preset awakening condition, wherein the preset awakening condition is a combination of the touch signals in the preset plurality of awakening point positions.
Further, when detecting whether the touch signals existing in the plurality of wake-up points in the preset area meet the preset wake-up condition, the specific detection mode may be performed as follows:
firstly, acquiring a wakeup point position corresponding to each touch signal in the preset area at the same moment to obtain trigger position information corresponding to a plurality of touch signals. Because the mutual capacitance type touch screen supports the function of a multi-point touch screen, when a user touches the touch screen, the position information of each position touched at the same time at present can be detected, in the embodiment of the invention, a plurality of awakening point positions in a preset area can be scanned specifically to realize the detection of touch signals, and when the touch signals exist, the positions corresponding to different touch signals at the same moment at present are obtained, namely, the fact that which awakening point positions detect the touch signals at the present moment can be understood.
Then, according to the trigger position information of the plurality of touch signals, trigger position combination information of the trigger position information of the plurality of trigger signals is determined. After the position information of the wake-up position corresponding to each touch signal, that is, the trigger position information according to the embodiment of the present invention, is obtained, the obtained trigger positions may be combined to obtain the trigger position combination information.
And finally, judging whether the trigger position combination information is consistent with the preset trigger position combination information in the preset awakening condition. The preset trigger position combination information may include combination information of different wake-up point locations, and after the trigger position combination information corresponding to the plurality of trigger signals of the current parent is determined, the trigger position combination information may be compared with the preset trigger position combination information, so as to determine whether the trigger position combination information and the trigger position combination information are consistent. Based on different judgment results, in the embodiment of the present invention, when it is judged that the currently obtained trigger position combination information is consistent with the preset trigger position combination information, it is indicated that the multi-point touch currently performed on the mutual capacitance type touch screen by the user is consistent with the preset touch position for waking up the touch screen, so that it can be determined that the operation performed by the current user is to wake up the touch screen, and therefore, it can be determined that a touch signal that the user wants to wake up the touch screen exists in the mutual capacitance type touch screen.
In addition, before the touch signal detection is performed, in the embodiment of the present invention, a current operation state of the mutual capacitance type touch screen may also be detected, specifically, whether the current mutual capacitance type touch screen is in a preset standby state is determined to be detected, so that a problem of power consumption waste caused by performing the touch signal detection on a preset area when the touch screen is in a working state can be ensured. Specifically, the judgment of whether the mutual capacitance type touch screen is in the preset standby state may be performed by judging a current screen scanning frequency of the mutual capacitance type touch screen, or detecting whether a screen in an area other than the preset area is scanned, and for this, the judgment manner may include, but is not limited to, the above manner, and no specific limitation is made herein, and the judgment manner may be selected according to an actual situation.
Therefore, when the mutual capacitance type touch screen is in an initial standby state, the touch position of the mutual capacitance type touch screen, which receives the touch signal, is obtained, and when the occurrence frequency of the touch position is determined to exceed a preset threshold value, the touch position is set as the awakening point position in the preset area, so that the function of setting the awakening point position based on the habit of a user can be realized, and the follow-up awakening mode of the touch screen is more convenient. And if the occurrence frequency of a plurality of different touch positions exceeds a preset threshold value, the different touch positions are set as different wake-up point positions in a preset area respectively, so that the mutual capacitance type touch screen can be woken up in a multi-point touch mode, and the problem of mistaken wake-up caused by waking up the touch screen in a single-point touch mode is avoided.

In this regard, the specific manner for waking up the mutual-capacitive touch screen may be based on any existing wake-up manner, and is not limited in particular herein.
204. And controlling the mutual capacitance type touch screen to be in a preset standby state.
