Detailed Implementation
[0026] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] Figure 1 This illustration shows an implementation flow diagram of a control method for a touch screen according to an embodiment of this application. Figure 1 ,include: Step 101: When the touch screen is in the first mode, detect the first sensing data of the first space. The first space is the space within a preset height range from the first surface. The first surface is the surface of the touch screen that can be touched. In the first mode, the touch screen responds to the touch signal acting on the first surface.
[0028] Step 102: In response to the first sensing data meeting the preset conditions, the touch screen is switched from the first mode to the second mode, wherein in the second mode, the touch screen responds to the touch signal acting on the first space.
[0029] The touchscreen includes a dedicated touchscreen integrated circuit with embedded firmware. By modifying the firmware parameters, the touchscreen can sense changes in the amount of charge in different spatial areas. This application, through modification of the firmware parameters, enables the touchscreen to sense changes in the amount of charge on a first surface and in a first space. The first surface is the touchscreen surface that the user can touch, and the first space is the space within a preset height range from the first surface. In this application, the first space is preferably a plane 2 cm above the first surface; however, any location within the sensing range of the touchscreen's sensors can be considered the first space.
[0030] Figure 2 This illustration shows a scenario where the touchscreen is in the first mode according to an embodiment of this application. Figure 1 ; Figure 3 This illustration shows a scenario where the touchscreen is in the first mode according to an embodiment of this application. Figure 2 .like Figure 2 and Figure 3 As shown, the touch screen itself has a reference capacitor. When the touch screen is in the first mode, the touch screen can sense the touch signal on the first surface. The touch signal generates a coupling capacitor. Based on the capacitance change generated by the touch signal on the first surface, the touch function of the touch screen is realized, which can be understood as contact-type touch control of the touch screen. Figure 4 This illustration shows a scenario in the second mode of the embodiments of this application. Figure 1 ; Figure 5 This illustration shows a scenario where the touchscreen is in the second mode according to an embodiment of this application. Figure 2 .like Figure 4 and Figure 5 As shown, when the touchscreen is in the second mode, it no longer senses touch signals from the first surface, but rather from the first space. The touch signals in the first space generate coupling capacitance. Based on the capacitance changes generated by the touch signals in the first space, the touchscreen function is achieved; this can be understood as air-based touch control. When it is inconvenient for users to directly touch the touchscreen, they can switch between touch modes to control it via air-based touch.
[0031] Specifically, when the touchscreen is in the first mode, first sensing data is obtained by detecting the first space. This first sensing data is capacitance change data or charge change data within the first space. When the first sensing data meets preset conditions, the touchscreen is switched from the first mode to the second mode, that is, from contact touch to air touch. The preset conditions are those that allow the touchscreen to switch modes, such as detecting charge change data that conforms to a preset shape.
[0032] This application configures the touchscreen to support both contact and air-based touch by adjusting the touchscreen firmware parameters. When the touchscreen is in the first mode but contact touch is inconvenient for the user, the system detects the first space. If the first sensing data of the first space meets preset conditions, the system can switch from air-based to contact touch, thus controlling the touchscreen. This solves the touchscreen control problem in specific scenarios, offering convenient operation, low cost, improved user experience, and expanded application scenarios for touchscreens.
[0033] In one possible implementation, when the touchscreen is in a first mode, detecting first sensing data in the first space includes: When the first function of the touch screen is enabled and in the first mode, the first sensing data of the first space is detected, and the first function is the function of switching touch modes.
[0034] Before detecting the first sensing data in the first space, it is first determined whether the first function of the touchscreen is enabled. This first function refers to the function of switching touch modes. When the first function of the touchscreen is enabled, it indicates that the touch mode can be switched. When the touchscreen is in the first mode, the first sensing data in the first space is detected. When the first sensing data meets the preset conditions, the touch mode can be switched from the first mode to the second mode. When the first function of the touchscreen is disabled, regardless of whether the first sensing data in the first space meets the preset conditions, the touch mode cannot be switched, and the touchpad can only be in the first mode, enabling only contact touch.
[0035] In one possible implementation, before switching the touchscreen from a first mode to a second mode in response to the first sensing data satisfying a preset condition, the method further includes: In response to the first sensing data indicating that the distance between the touch source and the first surface is within a preset height range and the duration of the distance is greater than the first preset duration, it is determined that the first sensing data meets the preset conditions.
[0036] In this embodiment, when the touch source causes a change in capacitance or charge in the first space, and the duration of the change in capacitance or charge is greater than a first preset duration, the touch screen can switch from the first mode to the second mode. Therefore, after detecting the first space to obtain the first sensing data, the first sensing data is analyzed to obtain the position corresponding to the first sensing data and the duration of the first sensing data, and the distance between the position corresponding to the first sensing data and the first surface is determined. Then, the duration of the first sensing data is compared with the first preset duration. When the distance between the position where the change in capacitance or charge occurs and the first surface is within a preset height range, and the duration of the change in capacitance and charge is greater than the first preset duration, it is determined that the first sensing data meets the preset conditions, and the screen can switch from the first mode to the second mode. That is, the first sensing data meets the preset conditions only when the position of the change in capacitance or charge is within the first space and the duration meets the first preset duration. This can prevent accidental switching of the touch mode due to misoperation.
[0037] In one possible implementation, before switching the touchscreen from a first mode to a second mode in response to the first sensing data satisfying a preset condition, the method further includes: In response to the first sensing data indicating that the touch source is a palm, the distance between the touch source and the first surface is within a preset height range, and the duration of the distance is greater than the first preset duration, it is determined that the first sensing data meets the preset conditions.
[0038] In this embodiment, when the touch source is a human hand, and the touch source causes a change in capacitance or charge in the first space, and the duration of the capacitance or charge change exceeds a first preset duration, the touch screen can switch from the first mode to the second mode. Therefore, after detecting the first space to obtain first sensing data, the first sensing data is analyzed to obtain the area and contour corresponding to the first sensing data, the position of the first sensing data, and the duration of the first sensing data. The area and contour corresponding to the first sensing data are matched with pre-stored hand features, and the distance between the position corresponding to the first sensing data and the first surface is determined. Then, the duration of the first sensing data is compared with the first preset duration. When the area and contour corresponding to the first sensing data match the pre-stored hand features, the distance between the position where the capacitance or charge change occurs and the first surface belongs to a preset height range, and the duration of the capacitance and charge change exceeds the first preset duration, it is determined that the first sensing data meets the preset conditions, and the screen can switch from the first mode to the second mode.
[0039] It is understood that the touch source is not limited to the one method of this application; in addition to the palm, it can also be other gesture features. Furthermore, if the detected first sensing data indicates that the corresponding area and contour show that the touch source is two palm features, and both palms are in the first space, and the duration of the two palms is satisfied with the first preset duration, then either one palm can be selected to respond or both palms can be responded to simultaneously.
[0040] In one possible implementation, the method further includes: The detection process of the first and second sensing data of the first surface includes: alternating scanning of each circuit channel of the first space and the first surface; If the first sensing data does not meet the preset conditions, the touch screen responds to the second sensing data to control the cursor.
[0041] In addition to detecting the sensing data of the first space, this application also needs to detect the second sensing data of the first surface. Specifically, the first and second scans of the touchpad can be alternately performed in each circuit channel at a preset frequency to obtain the first sensing data and the second sensing data. The first scan is used to detect the capacitance change of the first surface to obtain the first sensing data, and the second scan is used to detect the capacitance change of the first space to obtain the second sensing data.
[0042] Traditional touch control methods only offer contact-based touch, requiring only capacitance change detection on the first surface. This is achieved by scanning the circuit channels of the first surface of the touchscreen at a frequency of 100Hz to 140Hz. However, this application time-division multiplexes scanning channels within a complete scan cycle. In one channel, the first surface and the first space are scanned alternately for the first and second scans. Specifically, within a circuit channel, the first surface is scanned first, followed by the first space, or vice versa. Only after both scans are completed for a given channel does the scan proceed to the next channel. This ensures that the capacitance changes of the first surface and the first space are monitored in real-time and synchronously. The scanning frequency is increased from the traditional 100Hz-140Hz for touch only on the first surface to 200Hz or higher, ensuring sufficient time resolution to accommodate both the first and second scans.
[0043] Through this alternating scanning, two sets of capacitance change data can be obtained: one set represents the capacitance change data of the first surface, i.e., the second sensing data, and the other set represents the capacitance change data of the first space, i.e., the first sensing data. When the first sensing data does not meet the preset conditions, the switch from the first mode to the second mode cannot be realized. The touch screen can only perform contact-based touch, that is, respond to the second sensing data to control the cursor and move the cursor to the corresponding position according to the indication of the second sensing data.
[0044] In one possible implementation, such as Figure 6 As shown, the method also includes: Step 601: When the touchscreen is in the second mode, detect the third sensing data of the first space; Step 602: In response to the third sensing data meeting the preset conditions, the touch screen is switched from the second mode to the first mode.
[0045] Similarly, when the touchscreen is in the second mode, third sensing data can be obtained by detecting the first space. This third sensing data is also capacitance change data or charge change data within the first space. When the third sensing data meets preset conditions, the touchscreen is switched from the second mode to the first mode, i.e., from air-touch to contact-touch. The preset conditions are those that allow the touchscreen to switch modes. These preset conditions can be the same as or different from the preset conditions for switching from the first mode to the second mode. For example, the third sensing data might indicate that the distance between the touch source and the first surface is within a preset height range and the duration of this distance is greater than a second preset duration. Of course, the second preset duration and the first preset duration can be the same or different.
[0046] Figure 7This illustration shows a schematic diagram of the implementation flow of another control method for a touch screen according to an embodiment of this application. Figure 7 As shown, when the touchscreen is in the first mode, if the first sensing data of the first space meets the preset conditions, the touchscreen is switched from the first mode to the second mode; if the first sensing data of the first space does not meet the preset conditions, no mode switch is performed, and the touchscreen continues to operate in the first mode. When the touchscreen is in the second mode, if the third sensing data of the first space meets the preset conditions, the touchscreen is switched from the second mode to the first mode; if the third sensing data of the first space does not meet the preset conditions, no mode switch is performed, and the touchscreen continues to operate in the second mode.
[0047] Furthermore, when the touchscreen is in the second mode, by alternately scanning the data channels of the first surface and the first space, when a touch signal is detected on the first surface, the touchscreen can be directly switched from the second mode to the first mode.
[0048] In one possible implementation, the method further includes: When the touchscreen is in the second mode, detect the fourth sensor data of the first space; In response to the fourth sensor data indicating that the touch source is a finger, the cursor is controlled based on the movement of the finger.
[0049] In both the first and second modes, users perform touch operations based on finger swiping. After switching the touch screen from the first mode to the second mode, users can touch the touch screen in the first space. Therefore, when the touch screen is in the second mode, i.e., in the air-touch mode, the fourth sensing data in the first space is detected and analyzed. When the fourth sensing data matches the preset finger shape, the location where the charge changes is determined, and the coordinate information corresponding to the finger is determined. This coordinate information can be used to control the movement of the mouse cursor to achieve contact-based touch control of the touch screen.

The device includes: a detection module 801, configured to detect first sensing data obtained from a first space when the touch screen is in a first mode, wherein the first space is a space within a preset height range from a first surface, and the first surface is a touchable surface of the touch screen, wherein the touch screen responds to a touch signal acting on the first surface in the first mode; and a switching module 802, configured to switch the touch screen from the first mode to a second mode in response to the first sensing data meeting a preset condition, wherein the touch screen responds to a touch signal acting on the first space in the second mode.

[0054] In one possible implementation, the device further includes a second determining module 804, which is used to determine that the first sensing data meets the preset conditions before switching the touch screen from the first mode to the second mode in response to the first sensing data indicating that the touch source is a palm, the distance between the touch source and the first surface is within a preset height range, and the duration of the distance is greater than the first preset duration.
