Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
As mentioned in the background art, the access data reading period of the terminal device is much longer than the scanning period, which results in that the access data of the polling scanning cannot be effectively read, and thus causes resource waste, thereby being not favorable for the processing of reducing the power consumption of the terminal device.
In order to solve the above technical problem, the present application proposes a power consumption optimization method of a touch screen, in which method, a proximity sensor based on the registration of a touch screen as a virtual is provided, the detection mode of a proximity event is realized by reading capacitance data of the touch screen, in actual operation, the touch screen element may be registered at a hardware abstraction layer as a proximity event detection element, the registration process is to register the touch screen element as a virtual proximity sensor, thereby omitting the registration process of a physical proximity sensor, fully utilizing the original hardware resources, and avoids the opening of the terminal equipment, adapts to the development direction of the terminal equipment with a full screen, and, and the time for scanning the approaching data is determined according to the reading period, so that the waste of the scanning data is avoided, the power consumption of the terminal equipment is saved, and the cruising ability of the terminal equipment is improved.
The touch screen in the embodiment of the application is a capacitive screen which is self-integrated, self-capacitance data and mutual capacitance data on the touch screen can be detected, and the judgment of the proximity event is accurately performed based on the combination of the self-capacitance data and the mutual capacitance data. The method comprises the steps of acquiring self-contained data, judging whether the self-contained data is close to a target object, and acquiring the detection time length of the self-contained data according to the current application of the terminal equipment.
The following describes a power consumption optimization method and apparatus for a touch screen according to an embodiment of the present application with reference to the drawings.
Fig. 1 is a flowchart of a power consumption optimization method of a touch screen according to an embodiment of the present application, as shown in fig. 1, the method including:
The preset low-power-consumption operation scene includes a proximity detection scene where a user does not touch a finger or a stylus pen.
Specifically, whether a finger touches the touch screen or not can be determined according to the current proximity data of the touch screen, and if no finger touches the touch screen, the current scene is determined to be a preset low-power-consumption scene.
In an embodiment of the application, since the proximity data and the proximity distance have a corresponding relationship, the proximity distance to the touch screen is determined according to the proximity data of the touch screen, whether the proximity distance is in a preset low power consumption working scene is determined by determining whether the proximity distance is greater than a preset threshold, and when the proximity distance is greater than the preset threshold, the proximity distance is determined to be in the preset low power consumption scene.
And 102, if the touch screen is in a preset low-power-consumption working scene, determining the scanning duration of the self-contained data according to the current application of the terminal equipment, wherein the scanning duration is less than the duration corresponding to the approximate data reading period.
Specifically, if the touch screen is in a preset low power consumption working scene, it indicates that reducing the scanning frequency of the proximity data does not affect the proximity service, for example, when the preset low power consumption scene is detecting whether an obstacle is approaching, the scanning frequency of the proximity data is reduced, and the determination of the proximity event of the obstacle is not affected.
In order to reduce the power consumption of the terminal equipment in a low-power-consumption working scene, when the touch screen is in a preset low-power-consumption working scene, the scanning duration of the self-contained data is determined according to the current application of the terminal equipment, wherein the scanning duration is less than the duration corresponding to the access data reading period, and obviously, the power consumption is reduced compared with the situation that the self-contained access data is continuously scanned in the whole access data reading period. In addition, it should be understood that, in the actual execution process, applications currently running on the terminal device are different, and thus have different requirements on the detection sensitivity of the proximity event, for example, a game application based on proximity sensing (for example, once proximity is detected, light color change is performed to create a magic color effect) may have the highest requirement on the detection sensitivity of the proximity event, an application with a higher risk of false touch is based on a telephone, etc., an application with a higher requirement on the detection sensitivity of the proximity event may have a higher requirement on the detection sensitivity of the proximity event, an application with a lower risk of false touch is based on a WeChat, etc., and a detection sensitivity of the proximity event may have a lower requirement on the detection sensitivity of the proximity event, etc., so in the embodiment of the present application, in order to meet different requirements on the detection sensitivity of the proximity event of different applications, a corresponding relationship including application and reflected scanning duration is constructed in, the scanning duration corresponding to the current application of the terminal device can be obtained.
It should be noted that, according to different application scenarios, the manner of determining the scanning duration of the self-contained data according to the current application of the terminal device is different, and the following example is given:
example one:
the scanning duration corresponds to a duration of scanning a frame of self-contained data, for example, if the default scanning duration is 16ms and the proximity data reading period is 66ms, the scanning duration corresponds to a duration extended by 16ms, and the extended duration is less than 66 ms.
Specifically, a database including a correspondence between an application identifier of the terminal device and a time required for scanning self-contained data is established in advance, the preset database is queried according to the application identifier of the current application of the terminal device, and the time required for scanning one frame of self-contained data corresponding to the current application is obtained, for example, as shown in fig. 2-1, the application identifier of the current application a of the terminal device queries the preset database, the time required for obtaining one frame of self-contained data corresponding to the current application is 20ms, and then the scanning time of the self-contained data is extended from 16ms to 20 ms.
Example two:
the scanning duration corresponds to a duration required for scanning the number of frames of the self-contained data, for example, the default duration for scanning one frame of the self-contained data is 16ms, and the proximity data reading period is 66ms, and then the scanning duration corresponds to a duration for scanning multiple frames of the self-contained data, which is obviously an integral multiple of 16ms and less than 66 ms.
Specifically, a database including a corresponding relationship between an application identifier of the terminal device and a number of scanning frames required for scanning the self-contained data is pre-established, the preset database is queried according to the application identifier of the current application of the terminal device, and a time required by the number of scanning frames corresponding to the current application is obtained, for example, as shown in fig. 2-2, the application identifier of the current application a of the terminal device queries the preset database, the number of scanning frames corresponding to the current application is 1 frame, the corresponding scanning time is 16ms, and the scanning time of the self-contained data is limited to the self-contained data with the scanning 1 frame time being 16 ms.
Of course, in an embodiment of the application, if it is determined that the touch screen is in a preset proximity recognition activation working scene, for example, in a scene in which a finger touches the touch screen, proximity data of the touch screen, including self-capacitance data and mutual capacitance data, is continuously acquired according to a default scanning period, at this time, accuracy of proximity data acquisition is guaranteed, and accuracy of touch coordinate determination is improved.
And 103, determining the scanning time period and the scanning stopping time period of the self-contained data according to the approximate data reading time and the scanning duration.
And 104, acquiring self-capacitance data of the touch screen in the scanning time period, and stopping scanning the self-capacitance data of the touch screen in the scanning stopping time period so as to optimize the power consumption of the touch screen.
Specifically, the scanning time period and the scanning stopping time period of the self-contained data are determined according to the approximate data reading time and the scanning duration, so that the self-contained data of the touch screen are collected in the scanning time period, and the scanning of the self-contained data of the touch screen is stopped in the scanning stopping time period, so that the power consumption of the touch screen is optimized through the scanning time, for example, as shown in fig. 2-1 and 2-2, the scanning time period is reduced, the scanning is obviously stopped in a low-power-consumption working scene, the scanning duration is greatly reduced, and the power consumption of the terminal device is optimized.
It is emphasized that for some terminal equipments, which may not be able to perform complete stop scanning, the scanning-close state is understood as the scanning-stop state with a lower frequency.
In order to make the structure of the terminal device in the embodiments of the present application more clearly understood by those skilled in the art, the following describes the structure of the terminal device in some possible examples with reference to specific examples, and the following description refers to:
referring to fig. 3 to fig. 5, a terminal device 100 is provided in the present embodiment. The terminal device 100 comprises a touch screen 103 (target hardware element), a proximity sensor element 16, a light sensor 5 and a processor 23, the touch screen 103 comprises a display layer 13, the display layer 13 comprises a display area 1311, the proximity sensor element 16 is arranged below the display area 1311, thereby reducing the open hole of the terminal device, and the proximity sensor element 16 is used for emitting infrared light and receiving infrared light reflected by an object to detect the distance of the object to the terminal device 100.
The embodiment of the present application takes the terminal device 100 as a mobile phone as an example for application. The mobile phone can prevent misoperation of a user and is beneficial to saving the electric quantity of the mobile phone by arranging the proximity sensor element 16 to determine the distance between the mobile phone and the obstacle and making corresponding adjustment. When the user is answering or making a call and brings the mobile phone close to the head, the proximity sensor element 16 generates detection information by counting the time when the transmitter emits infrared light and the receiver receives reflected infrared light, and the processor 23 turns off the display layer 13 according to the detection information. When the mobile phone is far away from the head, the processor 23 turns on the display layer 13 again according to the detection information fed back by the proximity sensor element 16.
In some embodiments, the display layer 13 comprises an O L ED display layer.
In particular, the O L ED display layer has good optical transparency and better transmits visible and infrared light, thus, the O L ED display layer may not affect the proximity sensor element 16 to emit and receive infrared light while exhibiting content effects, the Micro L ED display layer may also be used as the display layer 13, and the Micro L ED display layer may also have good optical transparency to visible and infrared light
Referring to fig. 5, in some embodiments, the touch display screen 103 further includes a light-transmissive cover 11 and a touch layer 12. The light-transmitting cover plate 11 is arranged on the touch layer 12, the touch layer 12 is arranged on the display layer 13, the upper surface 131 of the display layer 13 faces the touch layer 12, and the light transmittance of the light-transmitting cover plate 11 and the touch layer 12 to visible light and infrared light is greater than 90%.
Specifically, the touch layer 12 is mainly used for receiving a user input signal and transmitting the user input signal to the circuit board for data processing, so as to obtain a specific position where the user touches the touch layer 12. It should be noted that the touch layer 12 is disposed On the display layer 13, which means that the touch layer 12 is In contact with the display layer 13, for example, In-Cell or On-Cell bonding technology can be used to bond the touch layer 12 and the display layer 13, which can effectively reduce the weight of the display layer 13 and the overall thickness of the display layer 13. The touch layer 12 being disposed on the display layer 13 may also mean that the touch layer 12 is disposed above the display layer 13 and spaced apart from the display layer 13.
In addition, the transparent cover plate 11 is disposed on the touch layer 12, so that the touch layer 12 and the internal structure thereof can be effectively protected, and the touch layer 12 and the display layer 13 are prevented from being damaged by external force. The light transmittance of the light-transmitting cover plate 11 and the light transmittance of the touch layer 12 to visible light and infrared light are both greater than 90%, which is not only beneficial for the display layer 13 to better show the content effect, but also beneficial for the proximity sensor element 16 arranged below the display layer 13 to stably emit and receive infrared light, and ensures the normal operation of the proximity sensor element 16.
In the embodiment of the present application, the touch layer 12 is composed of a capacitive plate, so in the implementation of the present application, the touch screen 103 may also be registered as a virtual sensor element, and when the screen is in a bright screen state, a proximity event is determined by a weak variation of a capacitance detected by the touch layer 12, where an electrode array included in the capacitive plate may implement detection of self-capacitance data and may also implement detection of mutual capacitance data.
