Description

Technical Field

[0001] This application belongs to the field of display panel technology, and particularly relates to a touch display panel and its touch driving method and touch display device. Background Technology

[0002] With the continuous development of display technology, the refresh rate of touch screens is also getting higher and higher in order to achieve better display effects. However, the application of high refresh rates often leads to a significant increase in display power consumption. Therefore, the display industry uses multi-refresh-rate displays to meet the application needs of different display scenarios.

[0003] To meet the needs of different display effects, touchscreens also employ corresponding report rates. A high report rate allows the touchscreen to respond faster to user touch operations, resulting in smoother touch interactions. A low report rate effectively reduces the overall power consumption of the touchscreen display, but it results in a slower response to user touch operations. However, in practical touchscreen applications, such as foldable touchscreens where half the screen is a high refresh rate display, the entire touchscreen remains at a high report rate, thus addressing the issue of insufficient power consumption reduction. Summary of the Invention

[0041] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0043] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0044] In the embodiments of this application, the term "electrical connection" can refer to a direct electrical connection between two components, or it can refer to an electrical connection between two components via one or more other components.

[0045] Various modifications and variations can be made to this application without departing from its spirit or scope, which will be apparent to those skilled in the art. Therefore, this application is intended to cover modifications and variations falling within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the embodiments provided in this application can be combined with each other without contradiction.

[0046] Before describing the technical solutions provided in the embodiments of this application, in order to facilitate understanding of the embodiments of this application, this application first specifically explains the problems existing in the related technologies:

[0047] As mentioned earlier, the inventors of this application have discovered that the application of high refresh rates leads to a significant increase in display power consumption. To match the needs of different display effects, touchscreens also employ corresponding touch reporting frequencies. In current touchscreen applications, especially foldable touchscreens, when one half of the foldable touchscreen displays at a high refresh rate and the other half at a low refresh rate, it still operates with high touch reporting for the entire screen.

[0048] Further research by the inventors revealed that in the aforementioned scenarios, such as when one half of the foldable touchscreen is used for video display, user interaction demands on that half are typically low, and touch requirements (touch sensitivity, touch response speed, etc.) are not high. Therefore, this half can be controlled to operate at a lower touch sampling rate to reduce power consumption. However, when the other half of the foldable touchscreen is used for applications such as keyboards and games, users place greater emphasis on the touch interaction experience. In this case, it is necessary to ensure that this half operates at a higher touch sampling rate to fully meet the user's high touch demands.

[0049] In view of the inventors' above-mentioned research findings, and in order to solve the problems of the prior art, this application provides a touch display panel and a touch driving method and a touch display device thereof. It should be noted that the embodiments provided in this application are not intended to limit the scope of this application.

[0050] The touch display panel provided in the embodiments of this application will be described below.

[0051] Figure 1 This is a schematic diagram of the structure of a touch display panel provided in an embodiment of this application. Figure 1 As shown, the touch display panel 100 includes a first area and a second area, the first area as follows: Figure 1 The upper part is shown. The second region is as follows. Figure 1 The lower half is shown. Both the first and second regions include multiple touch units. It should be understood that, in specific application scenarios, the display area of ​​the touch display panel 100 can be divided into two or more regions according to actual needs, and the signal type and / or signal amplitude of the touch driving signals in different regions can be adjusted according to the needs of the application environment to meet requirements such as touch accuracy and power consumption. The first and second regions can be display areas. The touch display panel 100 can be a foldable touch display panel.

[0052] Figure 1 In the first region, multiple touch units are electrically connected to a first touch signal line, so that the first touch signal line drives the multiple touch units in the first region for touch control. Touch units in the second region are electrically connected to a second touch signal line, so that the second touch signal line drives the multiple touch units in the second region for touch control.

[0053] Specifically, when the touch display panel 100 is in the first working mode, the first touch signal line transmits a first touch driving signal to the touch unit in the first area, and the second touch signal line transmits a second touch driving signal to the touch unit in the second area. The signal type of the first touch driving signal is different from the signal type of the second touch driving signal, and / or the signal amplitude of the first touch driving signal is different from the signal amplitude of the second touch driving signal.

[0054] The aforementioned first working mode can specifically refer to a working mode in which the actual touch application environment and touch requirements of the first and second areas of the touch display panel 100 are inconsistent. For example, if the first and second areas are used for application split-screen display, the first area can be used for touch operations of applications such as games and keyboards, while the second area can be used for touch operations of applications such as video playback and application desktop display. This application does not impose specific limitations on this.

[0055] It should be noted that this application is an improvement upon existing self-capacitive touch display panels. Therefore, the signal types of the first touch driving signal and the second touch driving signal are different; specifically, the self-capacitive signal types of the first and second touch driving signals may be inconsistent. For example, the first touch driving signal may be a mixture of self-capacitive and mutual-capacitive driving signals, while the second touch driving signal may consist only of either a self-capacitive or mutual-capacitive driving signal.

[0056] The signal amplitude of the first touch driving signal is different from that of the second touch driving signal. Specifically, it can mean that the signal amplitude of the self-capacitive driving signal in the first touch driving signal is inconsistent with that of the self-capacitive driving signal in the second touch driving signal, and / or that the signal amplitude of the mutual capacitive driving signal in the first touch driving signal is inconsistent with that of the mutual capacitive driving signal in the second touch driving signal, so that the power consumption of one display area in the first region and the second region can be reduced.

[0057] It should be added that the touch display panel in this application actually includes a plurality of scanning electrodes arranged along the first direction X and extending along the second direction Y, including as follows: Figure 1 The diagram shows TX1-TXx, TXx+1-TXy, and multiple others such as... Figure 1 The induction electrodes RX1-RXm are shown arranged along the second direction Y and extending along the first direction X.

[0058] Each touch unit in the touch display panel includes a pair of oppositely arranged scanning electrodes and sensing electrodes. For example, the scanning electrodes TX1-TXx in the plurality of touch units in the first region are electrically connected to the first touch signal line, and the scanning electrodes TXx+1-TXy in the plurality of touch units in the second region are electrically connected to the second touch signal line.

[0059] This application provides a touch display panel 100, which divides the panel into a first region and a second region. When the touch display panel 100 is in a first working mode, a first touch driving signal is transmitted to the touch unit in the first region by a first touch signal line, and a second touch driving signal is transmitted to the touch unit in the second region by a second touch signal line. The signal type of the first touch driving signal is different from that of the second touch driving signal, and / or the signal amplitude of the first touch driving signal is different from that of the second touch driving signal.

[0060] A touch display panel 100 according to an embodiment of this application partitions the panel. This results in different signal amplitudes and / or signal types for touch drive signals in display areas with different touch requirements when the panel is in a first operating mode. This effectively reduces the power consumption of the touch display panel. Self-capacitive drive signals can be used to implement self-capacitive touch detection, which improves touch sensitivity. Mutual-capacitive drive signals can be used to implement mutual-capacitive touch detection, enabling multi-touch sensing, etc.

[0061] In some more specific embodiments, in order to more reasonably reduce the power consumption of the touch display panel, when the touch display panel 100 is in the first working mode, the first touch driving signal includes a first mutual capacitance sub-driving signal and a first self-capacitance sub-driving signal, and the second touch driving signal includes any one of the following: a second mutual capacitance sub-driving signal, a second self-capacitance sub-driving signal, or a combination of a second mutual capacitance sub-driving signal and a second self-capacitance sub-driving signal; wherein the signal amplitude of the second mutual capacitance sub-driving signal is less than or equal to the signal amplitude of the first mutual capacitance sub-driving signal, and / or the signal amplitude of the second self-capacitance sub-driving signal is less than or equal to the signal amplitude of the first self-capacitance sub-driving signal.

[0062] Optionally, when the touch display panel 100 is in the first operating mode, the second touch driving signal can be controlled to switch between the following signal output modes: a second mutual capacitance sub-driving signal, a second self-capacitance sub-driving signal, or a combination of the second mutual capacitance sub-driving signal and the second self-capacitance sub-driving signal. Wherein, the signal amplitude of the second mutual capacitance sub-driving signal is less than or equal to the signal amplitude of the first mutual capacitance sub-driving signal, and / or, the signal amplitude of the second self-capacitance sub-driving signal is less than or equal to the signal amplitude of the first self-capacitance sub-driving signal.

[0063] Optionally, when the touch display panel 100 is in the first working mode, the aforementioned first touch driving signal includes only the first mutual capacitance sub-driving signal, and the second touch driving signal includes any one of the following: the second mutual capacitance sub-driving signal, the second self-capacitance sub-driving signal, or a combination of the second mutual capacitance sub-driving signal and the second self-capacitance sub-driving signal. The signal amplitude of the second mutual capacitance sub-driving signal is less than or equal to the signal amplitude of the first mutual capacitance sub-driving signal.

[0064] Optionally, when the touch display panel 100 is in the first working mode, the aforementioned first touch driving signal only includes the first self-capacitor driving signal, and the second touch driving signal includes any one of the following: a second mutual capacitor driving signal, a second self-capacitor driving signal, or a combination of the second mutual capacitor driving signal and the second self-capacitor driving signal. The signal amplitude of the second self-capacitor driving signal is less than or equal to the signal amplitude of the first self-capacitor driving signal.

[0065] When the touch display panel 100 is in the first working mode, the first touch driving signal includes one or both of the first mutual capacitance sub-driving signal and the first self-capacitance sub-driving signal, which can be set as needed.

[0066] Specifically, please see Figure 2 , Figure 2 This is a schematic diagram of a first touch driving signal provided in an embodiment of this application. For example... Figure 2 As shown, when the touch display panel 100 is in the first working mode, the first area can be in a normal touch working state. At this time, the first touch signal line transmits a first touch drive signal to the touch unit in the first area, including, for example, Figure 2 The diagram shows the first mutual capacitance sub-driving signal and the first self-capacitance sub-driving signal. Thus, based on the first touch driving signal including the first mutual capacitance sub-driving signal and the first self-capacitance sub-driving signal, the first region can satisfy both the touch self-capacitance driving requirements and the touch mutual capacitance driving requirements in current touch applications, thereby enabling the first region to respond faster to user touch operations, achieve higher touch accuracy, and provide smoother touch interaction with the user.

[0067] Please see below. Figure 3 , Figure 3 This is a schematic diagram of a second touch driving signal provided in an embodiment of this application. In some more specific embodiments, considering that mutual capacitance driving is more suitable for scenarios where users have multi-touch needs, while self-capacitance driving is more suitable for meeting users' single-touch needs. Based on this, as... Figure 3As shown, when the second area is in an environment with no touch application, low touch requirements, and multi-touch needs, the second touch driving signal can include only the second mutual capacitance sub-driving signal. The signal amplitude of the second mutual capacitance sub-driving signal is equal to the signal amplitude of the first mutual capacitance sub-driving signal, which is equivalent to the second mutual capacitance sub-driving signal being the same as the first mutual capacitance sub-driving signal. Thus, by providing the second mutual capacitance self-driving signal specifically, the touch power consumption of the second area can be reasonably and effectively reduced.

[0068] Please see Figure 4 , Figure 4 This is a schematic diagram of another second touch driving signal provided in an embodiment of this application. In some more specific embodiments, such as Figure 4 As shown, similarly, considering the differences in touch scenarios targeted by self-capacitive driving and mutual capacitive driving, when the second area is in an environment where there are no touch applications, the application touch requirements are not high, and the user has a need for waterproof or single-point touch with gloves, the second touch driving signal may only include the second self-capacitive sub-driving signal. The signal amplitude of the second self-capacitive sub-driving signal is equal to the signal amplitude of the first self-capacitive sub-driving signal, which is equivalent to the second self-capacitive sub-driving signal being the same as the first self-capacitive driving signal. In this way, by providing the second self-capacitive self-driving signal in a targeted manner, the touch power consumption of the second area can be reasonably and effectively reduced.

[0069] Please see Figure 5 , Figure 5 This is a schematic diagram of another second touch driving signal provided in an embodiment of this application. In some implementations, optionally, when the aforementioned second area is in an environment where there is no touch application or the application touch accuracy requirement is not high, such as... Figure 5 As shown, the second touch driving signal can include both a second mutual capacitance driving sub-signal and a second self-capacitance driving sub-signal. However, to effectively reduce the touch power consumption of the second area, the amplitude of the second mutual capacitance driving sub-signal is smaller than the amplitude of the first mutual capacitance driving sub-signal, and the amplitude of the second self-capacitance driving sub-signal is smaller than the amplitude of the first self-capacitance driving sub-signal. For example, if the amplitude of the first mutual capacitance driving sub-signal is 9V, the amplitude of the second mutual capacitance driving sub-signal can be 8V. Similarly, if the amplitude of the first self-capacitance driving sub-signal is 5V, the amplitude of the second self-capacitance driving sub-signal can be 4V.

[0070] It should be noted that in some other possible implementations, when the second touch driving signal output to the second region only includes the second mutual capacitance driving sub-signal, in order to further reduce the touch power consumption of the second region, the signal amplitude of the second mutual capacitance driving sub-signal may be smaller than the signal amplitude of the first mutual capacitance driving sub-signal.

[0071] Similarly, when the second touch driving signal only includes the second self-capacitive driving sub-signal, the signal amplitude of the second self-capacitive driving sub-signal can be smaller than the signal amplitude of the first self-capacitive driving sub-signal to more fully achieve the purpose of reducing power consumption. This application does not impose specific restrictions on this.

[0072] In some more specific embodiments, considering that the first and second areas of the aforementioned touch display panel 100 may be in the same touch application environment, for example, when the touch display panel 100 is playing a full-screen video or a full-screen game, the touch requirements of the first and second areas are basically the same.

[0073] Therefore, in order to ensure normal touch interaction of the touch display panel while minimizing power consumption, when the touch display panel 100 is in the second working mode, the first touch signal line transmits a first touch driving signal to the touch unit in the first area, and the second touch signal line transmits a second touch driving signal, the same as the first touch driving signal, to the touch unit in the second area. This is equivalent to the first touch driving signal and the second touch driving signal having the same signal type and amplitude. Both the first and second touch driving signals include a mixed signal of self-capacitive driving signal and mutual capacitive driving signal, which are output alternately, such as... Figure 2 As shown.

[0074] The aforementioned second working mode may specifically refer to a working mode in which the actual touch application environment and touch requirements of the first and second areas of the aforementioned touch display panel 100 are basically the same, and this application does not impose strict limitations on this.

[0075] Please see below. Figure 6 , Figure 6 This is a schematic diagram of another touch display panel provided in an embodiment of this application. For example... Figure 6 As shown, in some more specific embodiments, in order to more reasonably realize the output control of the first touch driving signal, the touch display panel 100 may optionally include: a first voltage regulating module 101 and a first driving module 102; and / or, the touch display panel 100 may include: a second voltage regulating module 103 and a second driving module 104.

[0076] The first terminal of the first voltage regulating module 101 is electrically connected to the touch driver chip, the first input terminal of the first driving module 102 is electrically connected to the touch driver chip, the second input terminal of the first driving module 102 is electrically connected to the second terminal of the first voltage regulating module 101, and the output terminal of the first driving module 102 is electrically connected to the first touch signal line.

[0087] Specifically, when the touch display panel 100 is in the second working mode, the third voltage regulating module 105 responds to the third voltage control signal provided by the touch driver chip and outputs a third driving signal to the third driving module 106.

In different application environments and under different operating modes, the signal type and / or signal amplitude of the second touch drive signal may be different.

[0089] It should be added that, considering that self-capacitance driving often involves electronic devices such as operational amplifiers, the first input terminal of the third driving module 106, which is electrically connected to the touch driver chip, and the first input terminal of the fourth driving module 108, which is electrically connected to the touch driver chip, can be used to receive the reference voltage of the touch driver chip during the self-capacitance driving operation amplifier process. This application does not impose any specific restrictions on this.

[0090] Please see below. Figure 8 , Figure 8 This is a schematic diagram of another touch display panel provided in an embodiment of this application. For example... Figure 8 As shown, in some more specific embodiments, in order to more reasonably and efficiently realize the signal amplitude control of the mutual capacitance driving sub-signal and the mutual capacitance driving sub-signal provided to the first touch signal line, optionally, the first voltage regulating module 101 may include a first adjustable linear regulator, and / or, the second voltage regulating module 103 may include a second adjustable linear regulator.

[0091] The first terminal of the aforementioned first adjustable linear regulator is electrically connected to the touch driver chip, and the second terminal of the first adjustable linear regulator is electrically connected to the second input terminal of the first driver module 102. Specifically, the first adjustable linear regulator can adjust the first drive signal output to the first driver module 102 according to different first voltage control signals provided by the touch driver chip.

[0092] The first terminal of the aforementioned second adjustable linear regulator is electrically connected to the touch driver chip, and the second terminal of the second adjustable linear regulator is electrically connected to the second input terminal of the second drive module 104. Specifically, the second adjustable linear regulator can adjust the second drive signal output to the second drive module 104 according to different second voltage control signals provided by the touch driver chip.

[0093] Please continue reading Figure 8 In some more specific embodiments, in order to further achieve reasonable control of the signal amplitude of the mutual capacitance driving sub-signal and the mutual capacitance driving sub-signal provided to the first touch signal line, the first voltage regulating module 101 may also include a first charge pump.

It can be equivalent to a stable voltage source electrically connected to the first adjustable linear regulator.

[0094] The second voltage regulating module 103 may further include a second charge pump, which is electrically connected to the second adjustable linear regulator and can be used to provide a stable voltage signal to the second adjustable linear regulator. It can be equivalent to a stable voltage source electrically connected to the second adjustable linear regulator.

[0095] Please see below. Figure 9 , Figure 9 This is a schematic diagram of another touch display panel provided in an embodiment of this application. For example... Figure 9 As shown, in some more specific embodiments, in order to more reasonably and efficiently realize the signal amplitude control of the mutual capacitance driving sub-signal and the mutual capacitance driving sub-signal provided to the second touch signal line, the third voltage regulating module 105 may optionally include a third adjustable linear regulator, and / or the fourth voltage regulating module 107 may include a fourth adjustable linear regulator.

[0096] The first terminal of the aforementioned third adjustable linear regulator is electrically connected to the touch driver chip, and the second terminal of the third adjustable linear regulator is electrically connected to the second input terminal of the third drive module 106. Specifically, the third adjustable linear regulator can flexibly adjust the third drive signal output to the third drive module 106 according to different third voltage control signals provided by the touch driver chip.

[0097] The first terminal of the aforementioned fourth adjustable linear regulator is electrically connected to the touch driver chip, and the second terminal of the fourth adjustable linear regulator is electrically connected to the second input terminal of the fourth driving module 108. Specifically, the fourth adjustable linear regulator can flexibly adjust the fourth driving signal output to the fourth driving module 108 according to different fourth voltage control signals provided by the touch driver chip.

[0098] Please continue reading Figure 9 In some more specific embodiments, in order to further achieve reasonable control of the signal amplitude of the mutual capacitance driving sub-signal and the mutual capacitance driving sub-signal provided to the second touch signal line, the third voltage regulating module 105 may also include a third charge pump, which is electrically connected to the third adjustable linear regulator and can be used to provide a stable voltage signal to the third adjustable linear regulator. It can be equivalent to a stable voltage source electrically connected to the third adjustable linear regulator.

[0099] The aforementioned fourth voltage regulating module 107 may further include a fourth charge pump, which is electrically connected to the fourth adjustable linear regulator and can be used to provide a stable voltage to the fourth adjustable linear regulator. It can be equivalent to a stable voltage source electrically connected to the fourth adjustable linear regulator.

[0100] It should be noted that, considering the actual production materials and power consumption of the touch display panel, the first, second, third, and fourth charge pumps mentioned above can be the same charge pump. In other words, the first, second, third, and fourth adjustable linear regulators specifically share the same charge pump for power supply, and this application does not impose specific restrictions on this.

[0101] In some more specific implementations, considering the self-capacitive driving scenario of a real self-capacitive touch display, in order to more reasonably realize the signal output of the first touch signal line and the second touch signal line, in the first stage of the first touch signal line transmitting the first self-capacitive sub-driving signal, the second touch signal line transmits the second self-capacitive sub-driving signal; and / or, in the second stage of the first touch signal line transmitting the first self-capacitive sub-driving signal, the second touch signal line transmits the second self-capacitive sub-driving signal.

[0102] In some more specific embodiments, further, in order to more rationally realize the signal output of the first touch signal line so that the multiple touch units in the first area of ​​the touch display panel 100 can better perform touch operations, the aforementioned first mutual capacitance sub-driving signal may include multiple effective pulses; and / or, the first self-capacitance sub-driving signal may include multiple effective pulses. The amplitude of the effective pulse of the first self-capacitance sub-driving signal is smaller than the amplitude of the effective pulse of the first mutual capacitance sub-driving signal.

[0103] In some more specific embodiments, further, in order to more rationally realize the signal output of the second touch signal line so that the multiple touch units in the second area of ​​the touch display panel 100 can better perform touch operations, the aforementioned second mutual capacitance sub-driving signal may include multiple effective pulses; and / or, the second self-capacitance sub-driving signal may include multiple effective pulses. The amplitude of the effective pulse of the second self-capacitance sub-driving signal is smaller than the amplitude of the effective pulse of the second mutual capacitance sub-driving signal.

[0104] The drive signal with a first frequency in the first region and the drive signal with a second frequency in the second region are coupled or self-coupled in the touch unit, then received and processed by the front-end analog amplifier, and finally passed through a narrow-bandwidth filter. The narrow-bandwidth filter includes specific capacitors and resistors that allow signals of a pre-defined specific frequency component to pass through while significantly attenuating or suppressing other frequency components. Signal filtering is a prerequisite and foundation for signal processing; its main purpose is to filter out useless interference signals or signals irrelevant to the target signal, thereby obtaining the signal required by the system. This signal is then converted to a digital signal by an analog-to-digital converter, and after digital filtering, the data required by the touch driver chip for calculating touch coordinates is obtained. This data is then sent to the central processing unit (CPU) for processing to obtain the coordinate data.

[0105] Based on the touch display panel provided in the above embodiments, this application also provides a touch display device, including the touch display panel provided in this application. Please refer to... Figure 10 , Figure 10 This is a schematic diagram of a touch display device provided in an embodiment of this application. Figure 10 The provided touch display device 1000 includes the touch display panel 100 provided in any of the above embodiments of this application. Figure 10 The embodiments use a touch-screen mobile phone as an example to describe the touch display device 1000. It is understood that the touch display device provided in this application embodiment can be other touch display devices with display functions, such as wearable touch products, computers, televisions, and automotive display devices; this application does not impose specific limitations on these. The touch display device provided in this application embodiment has the beneficial effects of the touch display panel 100 provided in this application embodiment. For details, please refer to the specific descriptions of the touch display panel 100 in the above embodiments; these descriptions will not be repeated here.

[0106] Based on the same inventive concept, this application also provides a touch driving method for a touch display panel, applicable to the touch display panel provided in any of the above embodiments of this application. Please refer to... Figure 11 , Figure 11 This is a schematic flowchart of a touch driving mechanism for a touch display panel provided in an embodiment of this application.

[0107] like Figure 11 As shown, the touch driving method of the touch display panel includes:

[0108] S1101. When the touch display panel is in the first working mode, control the first touch signal line to transmit the first touch driving signal to the touch unit in the first area, and control the second touch signal line to transmit the second touch driving signal to the touch unit in the second area; the signal type of the first touch driving signal is different from the signal type of the second touch driving signal, and / or the signal amplitude of the first touch driving signal is different from the signal amplitude of the second touch driving signal.

[0109] For example, the touch driver chip can detect the touch application environment of the touch display panel to determine whether the touch display panel is in the first working mode. Thus, if it is determined that the touch display panel is in the first working mode, the touch driver chip can control and adjust the first touch driving signal transmitted by the first touch signal line and the second touch driving signal transmitted by the second touch signal line.

[0110] In this way, the signal type of the first touch driving signal is different from that of the second touch driving signal, and / or the signal amplitude of the first touch driving signal is different from that of the second touch driving signal, thereby effectively reducing the touch power consumption of the touch display panel.

[0111] It should be added that the aforementioned first working mode can specifically be a working mode in which the actual touch application environment and touch requirements of the first and second areas in the aforementioned touch display panel are inconsistent, and this application does not impose specific restrictions on this.

[0112] This application provides a touch driving method for a touch display panel. When the touch display panel is in a first operating mode, a first touch driving signal is transmitted from a first touch signal line to a touch unit in a first area, and a second touch driving signal is transmitted from a second touch signal line to a touch unit in a second area. The signal types of the first and second touch driving signals are different, and / or, the signal amplitudes of the first and second touch driving signals are different. This touch driving method for a touch display panel, by partitioning the touch display panel, ensures that when the touch display panel is in the first operating mode, the signal amplitude and / or signal type of the touch driving signals in display areas with different touch requirements are different. This effectively reduces the power consumption of the touch display panel.

[0113] In some more specific embodiments, in order to reasonably realize the touch driving of the touch display panel in the foregoing embodiments, the touch driving method of the touch display panel may optionally include:

[0114] When the touch display panel is in the first working mode, the first touch driving signal includes a first mutual capacitive sub-driving signal and a first self-capacitive sub-driving signal, and the second touch driving signal includes any one of the following: a second mutual capacitive sub-driving signal, a second self-capacitive sub-driving signal, or a combination of the second mutual capacitive sub-driving signal and the second self-capacitive sub-driving signal; wherein the signal amplitude of the second mutual capacitive sub-driving signal is less than or equal to the signal amplitude of the first mutual capacitive sub-driving signal, and / or the signal amplitude of the second self-capacitive sub-driving signal is less than or equal to the signal amplitude of the first self-capacitive sub-driving signal.

[0115] Specifically, considering that mutual capacitance driving is more suitable for scenarios where users have multi-touch needs, while self-capacitance driving is more suitable for meeting users' single-touch needs, the second touch driving signal can include only the second mutual capacitance sub-driving signal when the second area is in an environment with no touch application, low touch requirements, and multi-touch needs. The signal amplitude of the second mutual capacitance sub-driving signal is equal to the signal amplitude of the first mutual capacitance sub-driving signal, which is equivalent to the second mutual capacitance sub-driving signal being the same as the first mutual capacitance sub-driving signal. Thus, by providing the second mutual capacitance self-driving signal specifically, the touch power consumption of the second area can be reasonably and effectively reduced.

[0116] When the second area is in an environment with no touch applications, low touch requirements, and where the user requires single-point touch with waterproof or gloved devices, the second touch driving signal can include only the second self-capacitive sub-driving signal. The signal amplitude of the second self-capacitive sub-driving signal is equal to the signal amplitude of the first self-capacitive sub-driving signal, which is equivalent to the second self-capacitive sub-driving signal being the same as the first self-capacitive sub-driving signal. Thus, by providing the second self-capacitive sub-driving signal specifically, the touch power consumption of the second area can be reasonably and effectively reduced.

[0117] Optionally, when the second area is in an environment where there is no touch application or the touch accuracy requirement is not high, the second touch driving signal may include both a second mutual capacitance driving sub-signal and a second self-capacitance driving sub-signal. However, to effectively reduce touch power consumption in the second area, the amplitude of the second mutual capacitance driving sub-signal is smaller than the amplitude of the first mutual capacitance driving sub-signal, and the amplitude of the second self-capacitance driving sub-signal is smaller than the amplitude of the first self-capacitance driving sub-signal.

[0118] It should be noted that in some other possible implementations, when the second touch driving signal output to the second region only includes the second mutual capacitance driving sub-signal, in order to further reduce the touch power consumption of the second region, the signal amplitude of the second mutual capacitance driving sub-signal can be smaller than the signal amplitude of the first mutual capacitance driving sub-signal. Similarly, when the second touch driving signal only includes the second self-capacitance driving sub-signal, the signal amplitude of the second self-capacitance driving sub-signal can be smaller than the signal amplitude of the first self-capacitance driving sub-signal to more fully achieve the purpose of reducing power consumption. This application does not impose specific limitations in this regard.

[0119] In some more specific implementations, considering that the first and second areas of the aforementioned touch display panel may be in the same touch application environment, such as when the touch display panel is playing a full-screen video or a full-screen game, the touch requirements of the first and second areas are basically the same.

[0120] Therefore, in order to ensure normal touch interaction of the touch display panel while minimizing power consumption, when the touch display panel is in the second operating mode, the first touch signal line is controlled to transmit a first touch driving signal to the touch unit in the first area, and the second touch signal line is controlled to transmit a second touch driving signal, the same as the first touch driving signal, to the touch unit in the second area. This is equivalent to the first touch driving signal and the second touch driving signal having the same signal type and amplitude.

[0121] The aforementioned two working modes can specifically refer to the working modes in which the actual touch application environment and touch requirements of the first and second areas of the aforementioned touch display panel are basically the same, and this application does not impose strict limitations on this.

[0122] Based on the touch driving method for a touch display panel provided in the above embodiments of this application, a touch driving device for a touch display panel provided in this application will be described below. Please refer to... Figure 12 , Figure 12 This is a schematic diagram of the structure of a touch driving device for a touch display panel provided in an embodiment of this application.

Therefore, typically, memory includes one or more tangible (non-transitory) computer-readable storage media (e.g., memory devices) encoded with software including computer-executable instructions, and when the software is executed (e.g., by one or more processors), it is operable to perform the operations described with reference to the methods according to one aspect of this disclosure.

[0127] The processor 1201 reads and executes computer program instructions stored in the memory 1202 to implement any of the touch driving methods for the touch display panel in the above embodiments.

Where appropriate, bus 1210 may include one or more buses. Although specific buses are described and illustrated in embodiments of this application, any suitable bus or interconnect is contemplated herein.
