[0037] Embodiments of the present application

[0038] The present disclosure will be further described in details by the following embodiments with reference to the accompanying drawings. It should be understood that the embodiments provided herein are only used to explain the present disclosure and not intended to limit the present disclosure. In addition, the embodiments provided herein are used to implement part of the present disclosure, and the technical solutions described in the embodiments of the present disclosure can be implemented in any combination without conflict.

[0039] It should be noted that in the embodiments of the present disclosure, the terms "comprising", "containing" or any other variants thereof are intended to cover non-exclusive inclusion, so that the method or device comprising a series of elements not only includes the elements explicitly described, but also includes other elements not explicitly listed or inherent to the method or device. Without more limitations, the element defined by the statement "comprising a" does not exclude the presence of other related elements (for example, steps in the method or units in the device, for example, the unit can be part of the circuit, part of the processor, part of the program or software, etc.) in the method or device comprising the element.

[0040] For example, the screen scanning method provided by the embodiments of the present disclosure comprises a series of steps, but the screen scanning method provided by the embodiments of the present disclosure is not limited to the steps described, and similarly, the screen scanning device provided by the embodiments of the present disclosure comprises a series of units, but the device provided by the embodiments of the present disclosure is not limited to comprising the units explicitly described, and can also comprise units required to be set when obtaining relevant information or processing based on information.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present disclosure belongs. The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0042] It can be understood that in the specific embodiments of the present application, relevant data is involved, and when the embodiments in the present application are applied to specific products or technologies, the permission or consent of the user needs to be obtained, and the collection, use and processing of relevant data need to comply with relevant laws, regulations and standards of relevant countries and regions.

[0043] FIG. 1 schematically shows a flowchart of a screen scanning method according to an embodiment of the present application. The execution subject of the screen scanning method can be any device with processing capability, such as a mobile phone, a smart watch, a television, a computer, and a household appliance.

[0044] As shown in FIG. 1, the screen scanning method can include steps S110-S130.

[0045] Step S110, intermittently performing display scanning in a display period in a single frame scanning period according to a specified time interval; step S120, performing touch control scanning in a field blanking period in the single frame scanning period; and step S130, performing electromagnetic control scanning in a time period in which the touch control scanning is not performed.

[0046] The single frame scanning period is a time period from starting scanning a frame of image to starting scanning a next frame of image, and the single frame scanning period includes a display period and a field blanking period (i.e. a vertical blanking period (VBlank)). The display period is a time period from starting scanning a frame of image to completing scanning the frame of image. The field blanking period is a time period from completing scanning a frame of image to starting scanning a next frame of image. For example, referring to FIG. 2, for a display screen, the single frame scanning period 210 can include a display period 211 and a field blanking period 212.

[0047] The display scanning in the display period in the single frame scanning period is intermittently performed according to a specified time interval, i.e. the display scanning is advanced by a segment of display scanning every specified time interval in the display period until scanning a frame of image, and the display scanning is paused in the specified time interval. The display scanning of a frame of image in the display period can make the effective display in the screen to be scanned.

[0048] For example, referring to FIG. 2, each of the small pits (pit 1-pit 16) in the display period 211 is a specified time interval, and the display scanning is paused in the specified time interval, and the display scanning is performed in a non-specified time interval. The display scanning is not performed in the field blanking period 212.

[0049] Further, the touch control scanning is performed in the field blanking period in the single frame scanning period, and the touch control scanning can scan the touch control (e.g. the touch control of a finger or some touch pen on the screen) signal on the screen, so that the device can further make a corresponding response, thereby realizing the touch control function. For example, referring to FIG. 2, for a touch screen, the touch control scanning is performed in the field blanking period 212, and the touch control scanning is not performed in the display period 211.

[0050] Further, the electromagnetic touch scanning is performed in the time period in which the touch touch scanning is not performed. For example, referring to FIG. 2, for the electromagnetic screen, the touch touch scanning is not performed in the display period 211, and the electromagnetic touch scanning can be performed in the display period 211; meanwhile, the touch touch scanning can be performed in the field blanking period 212, but if the touch touch scanning is stopped in the field blanking period 212, the electromagnetic touch scanning can also be performed in the time period in which the touch touch scanning is stopped in the field blanking period 212.

[0051] Therefore, the display scanning and the electromagnetic touch scanning can be simultaneously performed in the display period 211, but since the display scanning of the display period is intermittently performed according to the specified time interval, the display charging time of the display screen will not be too long to avoid energy accumulation, so that the interference of the display scanning on the electromagnetic touch scanning is small. In the field blanking period 212, only one of the electromagnetic touch scanning and the touch touch scanning is performed, and the multiple scans do not interfere with each other.

[0052] For example, the pits 1, 2, …, and 16 represent that the display scanning is not performed.

[0053] In this way, the display scanning and the touch touch scanning are respectively performed in the display period and the field blanking period in the single frame scanning period, so that the display scanning and the touch touch scanning do not interfere with each other; further, the electromagnetic touch scanning is performed in the time period in which the touch touch scanning is not performed, so that the multiple scans do not interfere with each other or the interference is small. Therefore, the mutual interference among the display scanning, the touch touch scanning, and the electromagnetic touch scanning can be effectively avoided, and the use performance of the screen is improved.

[0054] The following describes further optional specific embodiments of each step performed when the screen scanning is performed according to the embodiment of FIG. 1.

[0055] In one embodiment, the scanning time length of the display scanning performed between the specified time intervals is less than a predetermined threshold.

[0056] Referring to FIG. 2, each pit (pit 1 to pit 16) in the display period 211 is a specified time interval, and the scanning time length of the display scanning performed between the specified time intervals is the interval between the pits shown in FIG. 2. For example, the scanning time length of the display scanning performed between the pit 1 and the pit 2 is less than a predetermined threshold, and the scanning time length of the display scanning performed between the other pits is also less than the predetermined threshold. The predetermined threshold can be set according to the actual situation, and in one embodiment of the present application, the predetermined threshold is specifically 1 ms. The scanning time length of the display scanning performed between the specified time intervals is less than the predetermined threshold, so that the display charging time of the display screen will not be too long to avoid energy accumulation, and the influence on the electromagnetic touch scanning is avoided.

[0057] Further, in an embodiment, the number of the specified time intervals in the display period is greater than a predetermined number.

[0058] Referring to FIG. 2, each pit (pit 1 to pit 16) in the display period 211 is a specified time interval, and the display period 211 includes pit 1 to pit 16, that is, the number of specified time intervals in the display period 211 is 16. The number of specified time intervals in the display period is greater than a predetermined number, that is, the number of pits in the display period as shown in FIG. 2 is greater than a predetermined number, which can further prevent the display time of the display screen from being too long to avoid energy accumulation and further avoid affecting electromagnetic touch scanning.

[0059] The specified time interval and the scanning duration of the display scanning performed between the specified time intervals can be obtained in the following manner:

[0060] First, the predetermined time interval is determined as the specified time interval, and the predetermined duration is determined as the scanning duration.

[0061] Second, the specified time interval and the scanning duration are obtained by analyzing the usage habit data of the screen.

[0062] In the first manner, the predetermined time interval is directly determined as the specified time interval, for example, the predetermined 100 μs is determined as the specified time interval. In addition, the predetermined duration is directly determined as the scanning duration, for example, the predetermined duration of 0.8 ms is determined as the scanning duration.

[0063] In the second manner, the specified time interval and the scanning duration are obtained by analyzing the usage habit data of the screen (which can include the collected historical usage habit data of the display screen and the electromagnetic screen in the screen), and the specified time interval and the scanning duration are further dynamically determined for different screens. Specifically, a fine-tuned large model can be used to analyze the usage habit data of the screen to obtain the specified time interval and the scanning duration.

[0064] Further, in an embodiment of the present application, the specified time interval is less than a predetermined interval, which can further reduce the impact of display scanning on electromagnetic touch scanning while ensuring the display effect of the screen.

[0065] Further, in an embodiment, the electromagnetic touch scanning in the time period in which the touch touch scanning is not performed includes: performing the electromagnetic touch scanning in the display period and stopping the electromagnetic touch scanning in the field blanking period.

[0066] In this embodiment, the electromagnetic touch scanning is performed in the time period when the touch touch scanning is not performed, specifically, the electromagnetic touch scanning is performed in the display period 211 as shown in FIG. 2, and the electromagnetic touch scanning is stopped in the field blanking period 212, as shown in the timing diagram of the electromagnetic touch scanning in FIG. 2, the electromagnetic touch scanning can be in the high level state in the display period 211, and is in the low level in the field blanking period 212. In this way, the electromagnetic touch scanning and the touch touch scanning can be directly performed in different time periods, and the mutual influence of the electromagnetic touch scanning and the touch touch scanning can be directly avoided.

[0067] Further, in an embodiment, the screen includes a touch screen and an electromagnetic screen, and the touch screen and the electromagnetic screen are in signal intercommunication; the electromagnetic touch scanning performed in the time period when the touch touch scanning is not performed includes:

[0068] The first state signal is synchronized from the touch screen to the electromagnetic screen, so that the electromagnetic screen avoids the touch touch scanning performed by the touch screen; the second state signal is synchronized from the electromagnetic screen to the touch screen, so that the touch screen avoids the electromagnetic touch scanning performed by the electromagnetic screen.

[0069] In this embodiment, the electromagnetic touch scanning is performed in the time period when the touch touch scanning is not performed, specifically, the electromagnetic touch scanning is performed in the display period 211 as shown in FIG. 2, and the electromagnetic touch scanning is stopped in the field blanking period 212, as shown in the timing diagram of the electromagnetic touch scanning in FIG. 2, the electromagnetic touch scanning can be in the high level state in the display period 211, and is in the low level in the field blanking period 212. In this way, the electromagnetic touch scanning and the touch touch scanning can be directly performed in different time periods, and the mutual influence of the electromagnetic touch scanning and the touch touch scanning can be directly avoided.

[0070] Through the signal intercommunication, the touch touch scanning is limited to be performed in the field blanking period, and the electromagnetic screen can synchronize the second state signal to the touch screen to make the touch screen avoid the electromagnetic touch scanning performed by the electromagnetic screen, and then, in the case that the touch touch scanning is stopped due to the touch screen avoiding the electromagnetic touch scanning performed by the electromagnetic screen in the field blanking period, the electromagnetic touch scanning can also be performed in the time period when the touch touch scanning is stopped in the field blanking period 212. Moreover, the touch touch scanning is not performed in the display period 211, and the electromagnetic touch scanning can be performed in the display period 211.

[0071] In an embodiment, a first output pin of the first signal state is arranged on the touch screen, and the first output pin is connected with a general input and output pin of the electromagnetic screen; a second output pin of the second signal state is arranged on the electromagnetic screen, and the second output pin is connected with a general input and output pin of the touch screen.

[0072] Referring to FIG. 3, a first output pin (TP TE pin) 310 of a first signal state is arranged on a touch screen (TP), and the first output pin (TP TE pin) 310 is connected with a general input and output pin (EMR GPIO) 320 on an electromagnetic screen (EMR). A second output pin (EMR PDT pin) 330 of a second signal state is arranged on the electromagnetic screen (EMR), and the second output pin (EMR PDT pin) 330 is connected with a general input and output pin (TP GPIO) 340 on the touch screen (TP). Therefore, the touch screen (TP) and the electromagnetic screen (EMR) are connected by hardware, and the signal intercommunication between the touch screen and the electromagnetic screen is realized by the hardware connection.

[0073] For example, through the connection between the first output pin (TP TE pin) 310 and the general input and output pin (EMR GPIO) 320, the touch screen (TP) can synchronously transmit the first signal state (te) to the electromagnetic screen (EMR) in real time. Wherein, when the first signal state (te) is a high level 410 as shown in FIG. 4, it indicates that the touch control scanning is being performed, and then the electromagnetic screen (EMR) performs the action of avoiding the touch control scanning, so that the electromagnetic control scanning is not performed. When the first signal state (te) is a low level 420 as shown in FIG. 4, it indicates that the touch control scanning is not performed, so that according to the actual demand, the electromagnetic screen (EMR) does not need to perform the action of avoiding the touch control scanning, and the electromagnetic control scanning can be performed in an actual demand time period 430 as shown in FIG. 4.

[0074] Further, in an embodiment, in a first type of scenario, the working priority of the touch control scanning is higher than that of the electromagnetic control scanning; and in a second type of scenario, the working priority of the touch control scanning is lower than that of the electromagnetic control scanning.

[0075] Under this embodiment, the working priority of the touch control scanning and the electromagnetic control scanning is controlled in the first type of scenario and the second type of scenario, and the avoidance between the electromagnetic control scanning and the touch control scanning can be flexibly performed according to the demand. Wherein, the first type of scenario and the second type of scenario in the device can be divided according to the actual demand, and the present application does not make specific limitation thereto.

[0076] In the first type of scenario, the working priority of the touch control scanning is higher than that of the electromagnetic control scanning, and then in the first type of scenario, if the scanning avoidance is performed between the touch screen and the electromagnetic screen through the signal intercommunication, the working of the electromagnetic control scanning is stopped in priority to avoid the working of the touch control scanning.

[0077] In the second type of scenario, the working priority of the touch scanning is lower than the working priority of the electromagnetic scanning, and thus, in the second type of scenario, if the scanning avoidance is performed between the touch screen and the electromagnetic screen through signal intercommunication, the working of the touch scanning is stopped in priority to avoid the working of the electromagnetic scanning.

[0078] Further, in an embodiment, in any scenario, the working priority of the touch scanning is lower than the working priority of the electromagnetic scanning. In this embodiment, the device can be defaulted to have the working priority of the touch scanning lower than the working priority of the electromagnetic scanning in any scenario, and thus, in any scenario, if the scanning avoidance is performed between the touch screen and the electromagnetic screen through signal intercommunication, the working of the touch scanning is stopped in priority to avoid the working of the electromagnetic scanning.

[0082] In some embodiments of the present application, the screen includes a touch screen and an electromagnetic screen, and the touch screen and the electromagnetic screen are in signal intercommunication; the electromagnetic scanning module is configured to synchronize a first state signal from the touch screen to the electromagnetic screen, so that the electromagnetic screen avoids the working of the touch scanning performed by the touch screen; and synchronize a second state signal from the electromagnetic screen to the touch screen, so that the touch screen avoids the working of the electromagnetic scanning performed by the electromagnetic screen.

[0083] In some embodiments of the present application, in a first type of scenario, the working priority of the touch scanning is higher than the working priority of the electromagnetic scanning; and in a second type of scenario, the working priority of the touch scanning is lower than the working priority of the electromagnetic scanning.

[0084] In some embodiments of the present application, the working priority of the touch touch scanning is lower than the working priority of the electromagnetic touch scanning in any scenario.
