[0018] The implementation, functional features and advantages of the present application will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0019] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0020] In order to better understand the technical solutions of the present application, the following will be described in detail with reference to the accompanying drawings of the specification and specific implementation manners.

[0021] The main solution of the present application is: based on the initial electrical signal driving information, simultaneously transmit the initial electrical signal to the first control circuit and the second control circuit in the target area of the touch device, and respectively obtain the first feedback signal transmitted by the first control circuit and the second feedback signal transmitted by the second control circuit; based on the initial electrical signal driving information, the first feedback signal and the second feedback signal, determine the target electrical signal driving information corresponding to the target area of the touch device.

[0022] Currently, with the continuous development of liquid crystal display technology, the in-cell technology solution, that is, the technology solution of integrating the touch sensor into the display panel, has gradually become the mainstream. This solution realizes seamless switching between display and touch through time-division multiplexing. Specifically, when the display function of the display panel stops, the touch detection function starts. At this time, the same electrical signal is applied to the TP Sensor and the scan line driver, so as to sense the capacitance change in the circuit through the waveform change of the electrical signal, and then judge the touch position on the display panel through the capacitance change. However, in actual situations, there is a parasitic capacitance between the TP sensor and the scan line of the display panel, which will cause the waveform changes of the electrical signals transmitted to the TP sensor and the scan line to be asynchronous, thereby interfering with the touch detection function and seriously affecting the touch accuracy and sensitivity of the display panel. Therefore, how to improve the touch accuracy and sensitivity of the display panel is an urgent problem to be solved at present.

[0023] It should be noted that the touch accuracy of the display panel is a parameter / index used to measure the ability to generate accurate touch signals. Due to the existence of interference such as parasitic capacitance between circuit components in the existing touch panel, it is impossible to generate or generate accurate touch signals in a timely manner (such as missed detection of touch signals or generation of irrelevant touch signals). At this time, the touch accuracy of the touch panel is relatively low. However, the driving information determined by the touch device driving information generation method of the present application can effectively cope with the interference such as parasitic capacitance between circuit components in the existing touch panel, thereby improving the touch accuracy of the touch device.

[0024] The present application generates a corresponding initial electrical signal through the initial electrical signal driving information, and when synchronously transmitting it to the first control circuit and the second control circuit in the target area of the touch device, collects the first feedback signal transmitted in the first control circuit and the second feedback signal transmitted in the second control circuit. According to the difference between the first feedback signal and the second feedback signal and the initial electrical signal driving information, the target electrical signal driving information that can make the touch accuracy of the target area of the touch device higher is determined. During actual operation, a corresponding scan signal can be generated based on the target electrical signal driving information, and the target area of the touch device can be driven to perform a scan detection, so that the specific touch position can be judged more accurately and quickly, and the touch accuracy and sensitivity of the display panel can be improved.

[0025] It should be noted that the execution subject of this embodiment can be a driving information determination device, or a touch device with data processing, network communication, and program running functions, etc. This embodiment does not make specific limitations in this regard. Hereinafter, taking the driving information determination device as the execution subject as an example, this embodiment and the following embodiments will be described.

[0026] Based on this, the present application proposes a touch device driving information determination method for the first embodiment. Please refer to Figure 1 , the steps of the touch device driving information determination method include S10 - S20:

[0027] Step S10, based on the initial electrical signal driving information, simultaneously transmit the initial electrical signal to the first control circuit and the second control circuit in the target area of the touch device, and respectively obtain the first feedback signal transmitted by the first control circuit and the second feedback signal transmitted by the second control circuit;

[0028] It should be understood that for devices or equipment with display and touch functions such as display panels, the display part of the display screen can usually be divided into several display areas, and a touch sensor is configured for each display area. During operation, the working timing of the display area can be divided into periodically alternating scanning timing and display timing in a time-division multiplexing manner. During the scanning timing, the driving chip sends an electrical signal to the corresponding touch sensor through the scanning lines and signal lines in the display area, and the touch sensor can sense the capacitance change in the display area based on the waveform change of the received electrical signal, so as to determine the specific position of the touch point.

[0029] It should be noted that the target area of the touch device refers to a specific display area on the display panel (or other types of touch devices), which can be a minimum display unit or a combination of multiple minimum display units, and its specific size is not limited. The first control circuit and the second control circuit can be the circuit formed between the control driving chip corresponding to the target area of the touch device and the touch sensor, and it includes multiple communication lines for transmitting electrical signals (i.e., the signal lines and scanning lines mentioned above). Based on each communication line, the first control circuit is used to enable the driving chip to receive the electrical signal generated due to the pressure on the touch sensor, so as to determine whether the capacitance changes and thus determine whether it is touched; the second control circuit is used to scan the horizontal electrodes and vertical electrodes to facilitate the driving chip to read the specific position of the touch point. In actual situations, due to structural design reasons, there will always be a certain parasitic capacitance between the first control circuit and the second control circuit in the target area of the touch device. The charging and discharging characteristics of the parasitic capacitance will cause interference between the first control circuit and the second control circuit when transmitting electrical signals, resulting in asynchronous level changes on the first control circuit and the second control circuit. The above phenomenon will cause false touch or touch delay on the display panel, and the touch effect is not good.

[0030] It is easy to understand that in this embodiment, the initial electrical signal driving information refers to the electrical parameter setting information of the initial electrical signal used to drive the first control circuit and the second control circuit in the initial stage. When the driving current of the corresponding initial electrical signal in the initial electrical signal driving information is larger, the level change of the driving current used to drive the second control circuit and the first control circuit is faster; when the driving current of the initial electrical signal in the initial electrical signal driving information is smaller, the level change of the driving current used to drive the second control circuit and the first control circuit is slower. It should be noted that in actual situations, the level change speed of the driving current is neither as fast as possible nor as slow as possible, but it is necessary to ensure that the driving timings applied to the second control circuit and the first control circuit are as identical as possible, so as to minimize the poor touch control effect caused by the charge and discharge characteristics of the parasitic capacitance to the greatest extent. For each target area of the touch device, the driving currents it needs to provide to the second control circuit and the first control circuit are all different. Therefore, in the default state, the parameter of the driving current commonly used by a batch of normal display panel products can be used as the initial electrical signal driving information.

[0031] It is worth noting that in this embodiment, the initial electrical signal driving information does not refer to the parameter of the driving current provided to a single or a certain type of second control circuit or first control circuit alone, but refers to a set of parameters of the driving currents provided to the second control circuit and the first control circuit. For example, when a driving current setting value of level 1 is provided to the second control circuit and a driving current setting value of level 3 is provided to the first control circuit at the same time, the initial electrical signal driving information is (1, 3). In specific implementation, the initial electrical signal driving information can be used to control the change of the driving current magnitude on the corresponding first control circuit or second control circuit, thereby changing the corresponding level change speed. Therefore, the electrical parameters of the driving current provided to the second control circuit can be different from those of the driving current provided to the first control circuit (the driving current magnitudes on the second control circuit and the first control circuit can be different), but the required effect is to make the level change processes of the second control circuit and the first control circuit as synchronous as possible.

[0032] It should be noted that the initial electrical signal is a low-frequency electrical signal generated according to the initial electrical signal driving information, and is used to simulate a scanning signal for scanning touch points in the target area of the touch device. The first feedback signal is an electrical signal actually collected and transmitted by the first control circuit, and the second feedback signal is an electrical signal actually collected and transmitted by the second control circuit. In this embodiment, to keep the display panel not touched, the corresponding initial electrical signal can be generated according to the initially set initial electrical signal driving information, and the initial electrical signal is synchronously sent to the second control circuit and the first control circuit in the target area of the touch device. At this time, the first control circuit will transmit a corresponding first feedback signal, and a corresponding second feedback signal will also be transmitted on the second control circuit. The driving chip of the display panel can collect the first feedback signal and the second feedback signal.

[0033] For the convenience of understanding the above content, the following is an example for illustration. Please refer to Figure 2 , within a very short time period when the driving current changes in level, the initial electrical signal also needs to take a certain amount of time to change in level. In an ideal state, the waveforms, amplitudes, and phases of the level changes of the driving currents on the second control circuit and the first control circuit should be the same as the initial electrical signal shown in the figure. However, in actual situations, due to the existence of certain parasitic capacitances in the circuit, the charging and discharging effects of the parasitic capacitances cause the level changes to be non-linear changes, but in the form of arcs. If the driving current transmitted on the first control circuit is relatively small, the charging speed of its parasitic capacitance is relatively slow, and the process of the level change is relatively long; correspondingly, the driving current transmitted on the second control circuit is relatively large, the charging speed of its parasitic capacitance is relatively fast, and the process of the level change is relatively short. It can be found that the first feedback signal and the second feedback signal are out of sync in terms of the rate and timing of the level conversion.

[0034] Step S20: Based on the initial electrical signal driving information, the first feedback signal, and the second feedback signal, determine the target electrical signal driving information corresponding to the target area of the touch device.

[0035] It is easy to understand that the touch accuracy corresponding to the target electrical signal driving information is higher than that corresponding to the initial electrical signal driving information. In this embodiment, the first feedback signal and the second feedback signal can be compared to obtain the difference in the level change between the first feedback signal and the second feedback signal. Then, based on the level change difference and the initial electrical signal driving information, the target electrical signal driving information that can make the driving timings of the second control circuit and the first control circuit in the target area of the current touch device as consistent as possible can be obtained. Since the target electrical signal driving information can make the driving timings of the first control circuit and the second control circuit more consistent and the electrical interference between them smaller, when performing touch detection on the touch device through the target electrical signal driving information, its touch accuracy is higher than that of performing touch detection on the touch device through the initial electrical signal driving information.

[0036] It should be noted that in this embodiment, when the target electrical signal driving information is calculated, the driving chip inside the display panel can also be programmed, and the target electrical signal driving information is programmed into a certain register planned in the driving chip. When the display panel works normally later, the driving chip can retrieve the target electrical signal driving information from the register and perform scanning work based on this value.

[0037] It should be noted that in this embodiment, after the programming of the target electrical signal driving information is completed, the display panel can work normally based on the time-division multiplexing method. When the target area of the touch device is in the display timing, it realizes the function of displaying the image to be displayed to the outside, and when the target area of the touch device is in the scanning timing, it scans the target area of the touch device, so as to realize the function of detecting the specific coordinates of the touch point. In a specific implementation, if the target area of the touch device is in the scanning timing, the driving chip can retrieve the stored target electrical signal driving information, generate an initial electrical signal corresponding to a specific driving current based on the target electrical signal driving information, and transmit the initial electrical signal to the first control circuit and the second control circuit in the target area of the touch device. Then, based on the electrical signals fed back by each, the capacitance change of each area in the target area of the touch device is determined, so that the specific coordinates of each touch point in the target area of the touch device can be judged more accurately.

[0038] It should be noted that in this embodiment, the driving currents applied to the second control circuit and the first control circuit by the initial electrical signal may not be the same, and only need to ensure that the level change rates on the second control circuit and the first control circuit are as close as possible and the level change processes are as synchronous as possible.

[0039] In the above manner, when the display panel or other touch devices are in the scanning timing, the level changes between the first control circuit and the second control circuit in the target area of the touch device can be made more synchronous to the greatest extent, reducing the electrical interference caused by the charging and discharging of the parasitic inductance between the first control circuit and the second control circuit. Therefore, the capacitance change in the target area of the touch device can be detected more accurately, that is, the specific coordinates of the touch point can be detected more accurately and quickly, greatly improving the touch detection accuracy and touch sensitivity of the display panel.

[0040] An embodiment of the present application proposes a method for determining touch device driving information. This method generates a corresponding initial electrical signal through the initial electrical signal driving information, and when synchronously transmitting it to the first control circuit and the second control circuit in the target area of the touch device, collects the first feedback signal transmitted in the first control circuit and the second feedback signal transmitted in the second control circuit. According to the difference between the first feedback signal and the second feedback signal and the initial electrical signal driving information, determine the target electrical signal driving information that can make the touch accuracy in the target area of the touch device higher. During actual operation, a corresponding scanning signal can be generated based on the target electrical signal driving information and used to drive the target area of the touch device for scanning detection, so that the specific touch position can be judged more accurately and quickly, improving the touch accuracy and sensitivity of the display panel.

[0041] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar content as in the above-mentioned first embodiment can be referred to the above introduction and will not be repeated hereinafter. On this basis, please refer to Figure 3 , the steps of determining the target electrical signal driving information corresponding to the target area of the touch device based on the initial electrical signal driving information, the first feedback signal, and the second feedback signal include:

[0042] Step S21, respectively obtain the first level change time of the first feedback signal and the second level change time of the second feedback signal;

[0043] It should be noted that in this embodiment, during the process of a level change of the initial electrical signal, for example, from a low level to a high level, the time taken for the first feedback signal to change from the low level until it is completely stable at the high level can be collected respectively, that is, the first level change time; similarly, the time taken for the second feedback signal to change from the low level until it is completely stable at the high level can also be collected, that is, the second level change time.

[0044] Step S22, based on the first level change time and the second level change time, determine the expected level change time difference;

[0045] It is easy to understand that in this embodiment, it can be considered that the timing difference in the electrical signal transmission between the second control circuit and the first control circuit is mainly caused by the parasitic capacitance between the second control circuit and the first control circuit. Therefore, the theoretical timing difference caused by the parasitic capacitance during normal operation between the second control circuit and the first control circuit, that is, the expected level change time difference, can be estimated through the collected first level change time and the second level change time.

[0046] Step S23: Determine the expected drive compensation information based on the expected level change time difference and the preset time drive mapping table;

[0047] Step S24: Obtain the target electrical signal drive information based on the initial electrical signal drive information and the expected drive compensation information.

[0048] It should be noted that in this embodiment, the time drive mapping table refers to a comparison table that maps the charge and discharge time affected by the parasitic capacitance to the values of the drive current that needs to be adjusted. When obtaining the expected level change time, the electrical parameters of the drive current that needs to change currently can be read on the time drive mapping table in the form of reading the table, that is, the expected drive compensation information. At this time, the initial electrical signal drive information can be adjusted through the obtained expected drive compensation information to obtain the target electrical signal drive information that can make the timing between the second control circuit and the first control circuit as consistent as possible.

[0049] Furthermore, in this embodiment, before the step of simultaneously transmitting the initial electrical signal to the first control circuit and the second control circuit in the target area of the touch device based on the initial electrical signal drive information and respectively obtaining the first feedback signal transmitted by the first control circuit and the second feedback signal transmitted by the second control circuit, it further includes:

[0050] Step S01: Transmit the gradient detection signal to the first control circuit and the second control circuit based on the pre-set drive setting matrix, and respectively collect the first gradient feedback signal transmitted by the first control circuit and the second gradient feedback signal transmitted by the second control circuit;

[0051] It should be noted that the gradient detection signal can be understood as a low-frequency electrical signal that performs level conversion with the electrical parameters of various different drive currents. The drive setting matrix refers to a matrix composed of a set that respectively sets the drive currents applied to the second control circuit and the first control circuit in a gradient manner. For example, if the drive current on the second control circuit is set in gradients of 1, 2, and 3 gears, and the drive current on the first control circuit is also set in gradients of 1, 2, and 3 gears, then there can be 9 different electrical parameter setting values of the drive current such as (1, 1) to (3, 3).

[0052] It is easy to understand that the mean value of the drive current setting can be constructed from multiple sets of drive current setting values similar to the above, thereby generating a corresponding gradient detection signal. Each cycle of the gradient detection signal has a level conversion process corresponding to the drive current setting value in sequence. Similar to the relationship between the initial electrical signal, the first feedback signal, and the second feedback signal, the second control circuit will transmit a corresponding first gradient feedback signal based on the corresponding gradient detection signal, and the first control circuit will also transmit a corresponding second gradient feedback signal based on the corresponding gradient detection signal. The first gradient feedback signal and the second gradient feedback signal can be collected by the drive chip of the display panel.

[0053] Step S02: Based on the timing of the gradient detection signal, respectively obtain the gradient level change reference point of the gradient detection signal, the first gradient level change point of the first gradient feedback signal, and the second gradient level change point of the second gradient feedback signal.

[0054] It should be understood that in this embodiment, the timing of the gradient detection signal can be used as a reference timing to obtain the reference points before and after each level change of the gradient detection signal and the corresponding time-axis coordinates. The set of reference points corresponding to their respective time-axis coordinates is the gradient level change reference point. Correspondingly, based on the reference timing, the respective reference points corresponding to the first gradient feedback signal and their respective corresponding time-axis coordinates can be obtained, that is, the first gradient level change point is obtained, and the reference points corresponding to the second gradient feedback signal and their respective corresponding time-axis coordinates can be obtained, that is, the second gradient level change point is obtained.

[0055] Step S03: Determine the drive information of the initial electrical signal through the gradient level change reference point, the first gradient level change point, the second gradient level change point, and the drive setting matrix.

[0056] It should be noted that in this embodiment, in an ideal situation, when the gradient level change reference point, the first gradient level change point, and the second gradient level change point undergo a certain level change, the time-axis coordinates of the starting points of their respective corresponding level changes should be the same. However, in actual situations, due to the existence of noise interference, there will be a difference in the time-axis coordinates of the starting points of their respective corresponding level changes when undergoing a certain level change, that is, it can be considered that this time difference is caused by noise.

[0057] It is easy to understand that since the gradient level change reference point, the first gradient level change point, and the second gradient level change point can share a time axis, the time axis coordinates corresponding to each reference point can be placed in the time axis where the reference timing is located. At this time, the level change with the least noise generation can be determined by the time axis coordinates between the reference points in the time axis. And the drive current used for each level change corresponds one-to-one with a set of drive current setting values in the drive setting matrix. Therefore, for a batch of display panels, the initial electrical signal drive information with the least overall noise generation can be selected from the drive setting matrix.

[0058] Based on the first embodiment and / or the second embodiment of the present application, in the third embodiment of the present application, the same or similar content as in the above-mentioned first and second embodiments can be referred to the above introduction and will not be repeated hereinafter. On this basis, please refer to Figure 4 , the steps of determining the initial electrical signal drive information through the gradient level change reference point, the first gradient level change point, the second gradient level change point, and the drive setting matrix include:

[0059] Step S031, determining the first noise interference time of the first control circuit through the gradient level change reference point and the first gradient level change point, and determining the second noise interference time of the second control circuit through the gradient level change reference point and the second gradient level change point;

[0060] Step S032, screening out the minimum noise interference time from the first noise interference time and the second noise interference time;

[0061] It should be noted that for a certain level change, the time axis coordinate difference between the first gradient level change point of this level change and the corresponding gradient level change reference point is the first noise interference time; correspondingly, the time axis coordinate difference between the second gradient level change point of this level change and the corresponding gradient level change reference point is the second noise interference time. In this embodiment, after obtaining the first noise interference time and the second noise interference time, the minimum value among them can be screened out, which is the minimum noise interference time.

[0062] Step S033, obtaining the initial electrical signal drive information in the drive setting matrix based on the minimum noise interference time.

[0063] It is easy to understand that when screening out the minimum noise interference time, the corresponding first gradient level change point or second gradient level change point can be traced back through this minimum noise interference time, and thus the level change and the drive current setting value corresponding to the occurrence of this level change can be traced back, that is, the initial electrical signal drive information in the drive setting matrix is obtained.

[0064] Further, in this embodiment, after the steps of determining the first noise interference time of the first control circuit through the gradient level change reference point and the first gradient level change point, and determining the second noise interference time of the second control circuit through the gradient level change reference point and the second gradient level change point, the method further includes:

[0065] Step S034, when any one of the first noise interference time and the second noise interference time exceeds the preset noise interference time, re-execute the step of transmitting the gradient detection signal to the first control circuit and the second control circuit based on the pre-set driving setting matrix, and respectively collecting the first gradient feedback signal transmitted by the first control circuit and the second gradient feedback signal transmitted by the second control circuit.

[0066] It should be noted that, in this embodiment, the preset noise interference time is a parameter applicable to evaluating the noise magnitude. If the noise generated by this level change is too large, the first noise interference time or the second noise interference time will exceed the preset noise interference time, which may affect the result of the drive current compensation.

[0067] It is easy to understand that, in specific implementation, after obtaining the first noise interference time and the second noise interference time, it is also necessary to compare them with the preset noise interference time one by one. If any one of the first noise interference time or the second noise interference time exceeds the preset noise interference time, it can be considered that the test result of step S031 is abnormal, and step S031 needs to be re-executed to confirm whether this abnormality is caused by a defect in the product itself or due to the randomness of the test through the data of the re-test. In this way, the influence of the initial electrical signal driving information selected by the abnormal data on the subsequent test can be avoided, and the accuracy and stability of the drive current compensation can be improved.

[0068] Further, in this embodiment, after the step of determining the target electrical signal driving information corresponding to the target area of the touch device, the method further includes:

[0069] Step S30, burning the target electrical signal driving information corresponding to the target area of the touch device into the target storage area corresponding to the touch device, so that the touch device can obtain the corresponding target electrical signal driving information from the target storage area when in the scanning timing, and drive the target area of the touch device based on the corresponding target electrical signal driving information.

[0070] It should be noted that the target storage area refers to an area set in the touch device that can store information, which can be provided by one or more groups of registers in the control and drive chip inside the touch device.

[0071] It is easy to understand that in this embodiment, after the hardware structure of the touch device is fixed, the influence degree between the first control circuit and the second control circuit in the corresponding target area is also basically fixed. Therefore, when the target area needs to be driven each time, the same target electrical signal driving information can be used, instead of obtaining the target electrical signal driving information again in the scanning timing each time. In this way, the response speed during the touch scanning process of the touch device can be improved.

[0072] In a specific implementation, when determining the target electrical signal driving information currently corresponding to the target area of the touch device, the target electrical signal driving information can be burned into the target storage area of the touch device, so as to store the target electrical signal driving information. When the touch device enters the scanning timing again later, the previously burned target electrical signal driving information can be read from the target storage area, and a driving signal corresponding to the timing can be generated according to the read target electrical signal driving information, and sent to the first control circuit and the second control circuit of the target area of the touch device to drive the target area of the touch device to perform the scanning function.

[0073] The embodiment of the present application also provides a driving information determination device. Please refer to Figure 5 , the driving information determination device includes:

[0074] A signal transceiver module 10, configured to simultaneously transmit an initial electrical signal to the first control circuit and the second control circuit of the target area of the touch device based on the initial electrical signal driving information, and respectively obtain a first feedback signal transmitted by the first control circuit and a second feedback signal transmitted by the second control circuit;
