Detailed Description
Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.
Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.
In the related art, although noise is detected during the process of scanning the touch screen to obtain the touch signal, so as to avoid interference of the noise on the scanning process of the touch screen, the implementation manner may seriously affect the scanning speed and the reporting rate of the touch screen. In order to solve the above problems, the present application provides a touch screen scanning control device, method, chip, display panel and electronic device that realize fast point reporting while avoiding noise interference.
Fig. 1 shows a schematic diagram of a touch screen scanning control apparatus provided according to an embodiment of the present disclosure, where the apparatus may be applied to an electronic device with a touch screen, where the electronic device may be a mobile phone, a tablet computer, and the like, and the touch screen may be a capacitive touch screen, a resistive capacitive touch screen, and the like. As shown in fig. 1, the apparatus 10 includes: a first module 11, a second module 12 and a third module 13.
The first module 11 is configured to scan the touch screen according to the received first scanning frequency to obtain a touch signal of the touch screen.
A second module 12, configured to perform noise detection on the touch screen. In addition, if the second module 12 detects a noise signal, the noise signal may be further processed and analyzed to determine a noise frequency.
A third module 13, configured to mark, according to the noise frequency of the noise signal, a second scanning frequency that meets a marking condition in at least one second scanning frequency in the frequency table if it is determined that the second module 12 detects the noise signal.
Wherein the first scanning frequency is any unmarked second scanning frequency in the frequency table.
Before the first module 11 operates, the third module 13 may be further configured to read any one of unmarked second scanning frequencies from the frequency table, and send the second scanning frequency to the first module 11 as the first scanning frequency, so that the first module 11 scans the touch screen according to the received first scanning frequency.
According to the touch screen scanning control device provided by the embodiment of the disclosure, the first scanning frequency which scans the touch screen and prevents the scanning process from being interfered by noise can be selected quickly and automatically, so that the screen scanning module can continuously scan the touch screen at the first scanning frequency, and the touch screen scanning control device can realize quick report while avoiding noise interference.
The frequency table may include at least one second scanning frequency, and the second scanning frequencies may be arranged in a preset order in the frequency table. The preset sequence may be a sequence of numerical values, a numbering sequence of each second scanning frequency, and the like, which is not limited in this disclosure. The third module 13 may read each second scanning frequency in the frequency table according to the preset sequence.
Each second scanning frequency may be determined in advance according to an operating mode of the touch screen, and the like, which is not limited by the present disclosure. For example, when the touch screen is in the sleep state, a frequency table of the sleep state may be set, in which a plurality of second scanning frequencies lower in frequency are set. When the touch screen is in the wake-up state, a frequency table of the wake-up state may be set, and a plurality of second scanning frequencies with higher frequencies are set in the frequency table, which is not limited in this disclosure. The number of the second scanning frequencies in the frequency table may be 10, etc., and the present disclosure does not limit the number of the second scanning frequencies in the frequency table. If different frequency tables are set in different operating modes, before the first module 11 operates, the third module 13 reads any unmarked second scanning frequency from the frequency table corresponding to the current operating mode, and sends the second scanning frequency to the first module 11 as the first scanning frequency, so that the first module 11 scans the touch screen according to the received first scanning frequency. In the working process of the first module 11, if it is determined that the working mode changes, the third module 13 needs to determine a new first scanning frequency for the first module 11 from the frequency table corresponding to the changed working mode for the first module 11 again according to the changed working mode.
In a possible implementation, the frequency table may be stored in a rewritable memory, such as a flash memory, so that the third module 13 controls the memory to perform a read operation for each second scanning frequency, thereby reading the second scanning frequency in the frequency table.
In the working process of the first module 11, the second module 12 is also in a working state, so as to ensure that noise does not interfere with the scanning of the touch screen.
In a possible implementation, the third module 13 may also be configured to determine whether the second module 12 detects a noise signal; in the event that it is determined that the second module 12 does not detect a noise signal, it may be determined that the touch signal is not disturbed by noise during the scanning of the touch screen. The first module 11 may be used to continue scanning the touch screen according to the currently used first scanning frequency, and the second module 12 may be used to continue noise detection of the touch screen.
Through the mode, the first module can continuously and uninterruptedly scan the touch screen at the first scanning frequency, and the rapid point reporting is realized while the noise interference is avoided.
Fig. 2 illustrates a flowchart of operations performed by the third module 13 provided according to an embodiment of the present disclosure. As shown in fig. 2, the third module 13 is configured to perform operations including steps S10 to S70 after receiving the noise signal.
In step S10, the third module 13 determines that the second module 12 detects noise if it receives a noise signal from the second module 12. Since the noise is likely to interfere with the scanning process of the touch screen when the frequency of the noise is equal to or close to the first scanning frequency for scanning the touch screen, that is, the touch signal may be interfered by the noise. Therefore, after step S10 is performed, step S20 is performed.
In step S20, the third module 13 may determine whether each of the unmarked second scanning frequencies in the frequency table satisfies the marking condition according to the noise frequency of the noise signal when determining that the noise signal is detected by the second module 12. The third module 13 performs step S30 in a case where it is determined that the unmarked second scanning frequency exists in the frequency table and satisfies the marking condition. The third module 13 continues to execute step S10 if it is determined that each of the unmarked second scanning frequencies in the frequency table does not satisfy the marking condition.
In one possible implementation, the labeling condition may include: the unmarked second scanning frequency in the frequency table is equal to the noise frequency.
Fig. 3 shows a schematic diagram of another touch screen scanning control device provided according to an embodiment of the present disclosure. In one possible implementation, as shown in fig. 3, the third module 13 may include:
the comparison sub-module 131 is configured to sequentially compare each of the unmarked second scanning frequencies with the noise frequency to obtain a comparison result corresponding to each of the unmarked second scanning frequencies, where each of the comparison results is used to indicate whether the corresponding unmarked second scanning frequency is equal to the noise frequency.
By analyzing the comparison result corresponding to each unmarked second scanning frequency, whether each unmarked second scanning frequency is equal to the noise frequency can be determined, and whether each unmarked second scanning frequency meets the marking condition can be further judged.
In step S30, the third module 13 marks the second scanning frequency satisfying the marking condition among the unmarked second scanning frequencies in the frequency table. And after performing step S30, step S40 and/or step S60 are/is performed.
The third module 13 may mark the second scanning frequency satisfying the marking condition in the frequency table by adding a label to the second scanning frequency satisfying the marking condition, and the like. If the third module 13 recognizes that the second scanning frequency is marked, it may determine that the second scanning frequency is in an unavailable state, that is, if the first module 11 is used to scan the touch screen according to the second scanning frequency, the obtained touch signal of the touch screen may be interfered by noise. If the third module 13 recognizes that the second scanning frequency is not marked, it may determine that the second scanning frequency is in a usable state, that is, if the first module 11 is used to scan the touch screen according to the second scanning frequency, the obtained touch signal of the touch screen is not interfered by noise.
In this way, by marking the second scanning frequency satisfying the marking condition in the frequency table, the third module 13 can determine whether the second scanning frequency is in the usable state by only identifying the mark of the second scanning frequency in reading the second scanning frequency from the frequency table as the first scanning frequency.
As shown in fig. 2, in step S40, after completing the marking (i.e., step S30), the third module 13 determines whether the marked second scanning frequency in the frequency table is equal to the first scanning frequency currently used by the first module 11, so as to determine whether the first scanning frequency currently used by the first module 11 is in a usable state.
In the case where the third module 13 determines that the marked second scanning frequency in the frequency table is equal to the first scanning frequency currently used by the first module 11, it determines that the first scanning frequency currently used by the first module 11 is in the unavailable state, and may execute step S50. The third module 13 determines that the first scan frequency currently used by the first module 11 is in a usable state in case that it is determined that the marked second scan frequency in the frequency table is not equal to the first scan frequency currently used by the first module 11, and may perform step S10.
As shown in fig. 2, in step S50, the third module 13 sends any unmarked second scanning frequency in the frequency table as the first scanning frequency to the first module 11 when determining that the marked second scanning frequency in the frequency table is equal to the first scanning frequency currently used by the first module 11.
In a case where it is determined that the marked second scanning frequency in the frequency table is equal to the first scanning frequency currently used by the first module 11, the third module 13 may send, as the first scanning frequency, the unmarked second scanning frequency currently sorted before in the frequency table to the first module 11 according to a preset order.
In this way, when it is determined that the marked second scanning frequency in the frequency table is not equal to the first scanning frequency currently used by the first module 11, the third module 13 sends any unmarked second scanning frequency in the frequency table to the first module 11 as the first scanning frequency, so that the first module 11 can directly scan the touch screen by using the new first scanning frequency in the available state without stopping scanning the touch screen.
As shown in fig. 2, in step S60, after performing step S30, the third module 13 may count the number of marked second scanning frequencies in the frequency table. And judging whether the number of the marks is equal to the number of the second scanning frequencies recorded in the frequency table. The third module 13 determines that all the second scanning frequencies in the frequency table are marked in the case where the number of marks is equal to the number of second scanning frequencies recorded in the frequency table, and performs step S70. In the case where it is determined that the number of marks is not equal to the number of second scanning frequencies recorded in the frequency table, the third module 13 determines that all of the second scanning frequencies in the frequency table are not marked, and may continue to perform step S10.
In this way, by determining whether the number of the marks is equal to the number of the second scanning frequencies recorded in the frequency table, it can be determined whether all the second scanning frequencies in the frequency table are marked.
In a possible implementation manner, as shown in fig. 3, the third module 13 may further include: and a counting sub-module 132 for counting the number of marked second scanning frequencies in the frequency table.
As shown in fig. 2, in step S70, the third module 13 sends an interrupt signal if it detects that each second scanning frequency in the frequency table is marked.
In one possible implementation, as shown in fig. 3, the apparatus may further include a fourth module 14. The fourth module 14 is configured to determine that, when receiving the interrupt signal, each second scanning frequency in the frequency table is marked and is in an unavailable state, and update each second scanning frequency in the frequency table according to the received interrupt signal, where each second scanning frequency in the updated frequency table is different from the used second scanning frequency.
When receiving the interrupt signal sent by the third module 13, if it is determined that the frequency table in which the second scanning frequencies are all marked corresponds to the target operating mode, the fourth module 14 may update the second scanning frequencies in the frequency table, so that each of the second scanning frequencies in the updated frequency table is different from the used second scanning frequency, and the updated frequency table is applicable to the target operating mode.
Wherein a memory for storing the frequency table may be provided in the fourth module 14, which is not limited by the present disclosure.
After receiving the interrupt signal, the fourth module 14 determines that each second scanning frequency in the frequency table is marked, and then updates each second scanning frequency in the frequency table, so that the third module 13 can read a new second scanning frequency from the updated frequency table, and send the new second scanning frequency as the first scanning frequency to the first module 11, so that the first module 11 scans the touch screen according to the new first scanning frequency, thereby reducing interaction frequency required for interaction between the third module 13 and the fourth module 14 to update the second scanning frequency, reducing interaction time, and realizing fast reporting while avoiding noise interference.
Fig. 4 shows a flowchart of a touch screen scanning control method provided according to an embodiment of the present disclosure, which includes steps S11 to S12.
In step S11, a touch screen is scanned according to a first scanning frequency to obtain a touch signal of the touch screen, and noise detection is performed on the touch screen.
In step S12, in the case where a noise signal is detected, a second scanning frequency satisfying a labeling condition among at least one second scanning frequency in the frequency table is labeled according to a noise frequency of the noise signal.
Wherein the first scanning frequency is any unmarked second scanning frequency in the frequency table.
According to the touch screen scanning control method provided by the embodiment of the disclosure, the first scanning frequency which can scan the touch screen and enable the scanning process not to be interfered by noise can be selected quickly and automatically, the touch screen is continuously scanned at the first scanning frequency uninterruptedly, and the quick report of points is realized while the noise interference is avoided.
In one possible implementation, the method may further include: and if the marked second scanning frequency in the frequency table is equal to the first scanning frequency, replacing the first scanning frequency with any unmarked second scanning frequency in the frequency table.
In a possible implementation manner, the marking condition may include: the second scan frequency in the frequency table that is not marked is equal to the noise frequency.
