[0033] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the embodiments of the present application should fall within the scope of protection of the embodiments of the present application.

[0034] At present, display panels including but not limited to AMOLED (Active-matrix organic light-emitting diode) touch panels are increasingly being used in touch display devices. However, the display effect of the display panel with touch function is not good, and it is easy to have undesirable phenomena such as water ripples, which reduces the display effect and touch effect of the display panel. For example, taking the AMOLED touch display panel as an example, due to the structural design requirements of some touch display devices, there is inevitably a physical overlap between the display signal line (used to transmit the display control signal) and the touch detection signal line (used to transmit the touch detection signal) of the display panel, and an organic layer is set between the two. However, there is a coupling effect between the display signal line and the touch detection signal line (for example, parasitic capacitance is generated between the two due to the coupling effect, etc.), and the organic layer cannot effectively eliminate the influence of the coupling effect. The coupling effect causes the display control signal and the touch detection signal of the display panel to interfere with each other, which easily causes the display panel to have the undesirable phenomenon of water ripples and reduces the touch effect of the display panel.

[0035] In view of this, a technical solution is provided in an embodiment of the present application to better balance the display effect and the touch effect of a display panel with a touch function.

[0036] Figure 1 A flow chart of the steps of a display control method in an embodiment of the present application is shown. Figure 1 As shown, the display control method provided in the first aspect of the present application includes the following steps S102 and S104, specifically:

[0037] S102: controlling the display panel to enter a first display state for display according to a first display control signal, so that a display frequency of the display panel is less than a preset frequency;

[0038] S104: In the first display state, touch detection is performed on the display panel according to the first touch detection signal, the touch reporting signal of the first touch detection signal is located in the blank area of ​​the first display control signal, and there are at least two touch reporting signals in the blank area of ​​the first display control signal.

[0039] Based on this, the display control method in the embodiment of the present application can control the display panel to enter the first display state for display according to the first display control signal. In the first display state, the display frequency of the display panel is less than the preset frequency. Then, in the first display state, touch detection is performed on the display panel according to the first touch detection signal, and the touch reporting signal of the first touch detection signal is in the blank area of ​​the first display control signal. In this way, the touch reporting of the first touch detection signal can be realized in the blank area of ​​the first display control signal, thereby avoiding the mutual interference between the action of the first display control signal and the touch reporting of the first touch detection signal. In addition, there are at least two touch reporting signals in the blank area of ​​the first display control signal, thereby increasing the frequency of touch reporting. Therefore, the embodiment of the present application can improve the adverse phenomenon of water ripples caused by the mutual interference between the display control signal and the touch detection signal on the display panel, and improve the display effect of the display panel, while effectively improving the touch effect. It can be seen that the technical solution can better take into account the display effect and touch effect of the display panel with touch function.

[0040] The display control method in the embodiment of the present application can be applied to any display panel with a touch function as long as it can meet the requirements. For example, in some optional application scenarios, the display panel can be an active matrix organic light emitting diode AMOLED display panel. The AMOLED display panel is a display panel with AMOLED (active matrix organic light emitting diode) material as the main material, which has the characteristics of fast response speed, higher contrast, wider viewing angle, strong outdoor readability and low power consumption.

[0041] It should be understood that applying the display control method in the embodiment of the present application to the display control of the AMOLED display panel can improve the undesirable phenomenon of water ripples on the AMOLED display panel caused by the mutual interference between the display control signal and the touch detection signal, thereby improving the display effect of the AMOLED display panel and improving the touch effect at the same time.

[0042] In an embodiment of the present application, the display control signal may be a signal for performing display control on the display panel. It can affect the display effect of the display panel. In the present application, the display control signal may include a first display control signal and a second display control signal. By performing display control on the display panel according to the first display control signal, the display panel may enter a first display state, and in the first display state, the display frequency of the display panel is less than a preset frequency. By performing display control on the display panel according to the second display control signal, the display panel may enter a second display state, and in the second display state, the display frequency of the display panel is equal to a preset frequency. The blank area of ​​the display control signal may be a non-action time section of the display control signal, during which the display control signal does not act, and therefore performing touch reporting during this period avoids mutual interference with the display control signal.

[0043] For example, in the first display state, since the display frequency of the display panel is less than the preset frequency, the display panel will keep the picture without refreshing for a period of time when displaying the picture. At this time, the first display control signal does not act, and the refresh time is in the action area of ​​the first display control signal, and this period of non-refresh time is the blank area of ​​the first display control signal (for example, when the preset frequency is 120Hz, if the display panel has a display frequency of 30Hz, the first picture is refreshed and the next three pictures are kept, then the next three pictures are all in the blank area of ​​the first display control signal, and the first picture is in the action area). In addition, the blank area of ​​the first display control signal also includes the time segment when the first display control signal does not act between the adjacent picture refresh and picture keep. For example, in the second display state, since the display frequency of the display panel is equal to the preset frequency, the blank area of ​​the second display control signal is the time segment when the second display control signal does not act between the adjacent two picture refreshes.

[0044] In an embodiment of the present application, the touch detection signal may be a signal for performing touch detection on the display panel. In the present application, the touch detection signal may include a first touch detection signal and a second touch detection signal. The first touch detection signal is a touch detection signal for performing touch detection on the display panel in the first display state of the display panel. The second touch detection signal is a touch detection signal for performing touch detection on the display panel in the second display state of the display panel. The touch reporting signal may be a signal of the touch detection signal for reporting the result of the touch detection. For example, the display panel may be touch-detected according to the touch detection signal to determine the touch position information when the user's finger touches the display panel, and the touch position information may be reported as the result of the touch detection through the touch reporting signal to realize the touch reporting. For another example, if the touch position information when the user's finger touches the display panel is not detected, it may be reported as the result of the touch detection with no touch position information to realize the touch reporting.

[0045] In the embodiment of the present application, there are at least two touch reporting signals in the blank area of ​​the first display control signal. Therefore, at least two touch reporting signals can be performed in each blank area of ​​the first display control signal, thereby increasing the frequency of touch reporting signals and effectively improving the touch effect.

[0046] In some optional embodiments, the display control method in the present application also includes: controlling the display panel to enter a second display state for display according to a second display control signal, so that the display frequency of the display panel is equal to a preset frequency; in the second display state, performing touch detection on the display panel according to a second touch detection signal, and the touch point reporting signal of the second touch detection signal is located in the blank area of ​​the second display control signal.

[0047] Based on this, in the embodiment of the present application, the display panel is controlled to enter the second display state for display according to the second display control signal. In the second display state, the display frequency of the display panel is equal to the preset frequency. Then, in the second display state, touch detection is performed on the display panel according to the second touch detection signal, and the touch reporting signal of the second touch detection signal is in the blank area of ​​the second display control signal. In this way, the touch reporting signal of the second touch detection signal can be realized in the blank area of ​​the second display control signal, thereby avoiding the mutual interference between the action of the second display control signal and the touch reporting signal of the second touch detection signal in the second display state where the display frequency of the display panel is equal to the preset frequency, thereby further improving the undesirable phenomenon of water ripples on the display panel caused by the mutual interference between the display control signal and the touch detection signal, improving the display effect of the display panel, and improving the touch effect.

[0048] Optionally, one or more touch reporting signals may exist in the blank area of ​​the second display control signal.

[0049] In some optional embodiments, the number of touch point reporting signals located in the blank area in the first display state is greater than the number of touch point reporting signals located in the blank area in the second display state.

[0050] Therefore, compared with the second display state of the display panel, the frequency of touch reporting of the display panel in the first display state can be increased in the present application, and the display frequency of the first display state is lower than the display frequency of the second display state, which can better balance the display effect and touch effect of the display panel at a lower display frequency.

[0051] The specific number of touch reporting signals in the above two display states can be set as needed. For example, in an optional example, the number of touch signals located in a single blank area of ​​the first display control signal in the first display state is 2, and the number of touch signals located in a single blank area of ​​the second display control signal in the second display state is 1. In another optional example, the number of touch signals located in a single blank area of ​​the first display control signal in the first display state is 4, and the number of touch signals located in a single blank area of ​​the second display control signal in the second display state is 2. In yet another optional example, the number of touch signals located in a single blank area of ​​the first display control signal in the first display state is 4, and the number of touch signals located in a single blank area of ​​the second display control signal in the second display state is 2. The above examples are only used to facilitate the understanding of the embodiments of the present application and are not intended to limit the embodiments of the present application.

[0052] In the embodiment of the present application, the preset frequency can be set as needed, and no specific limitation is made here. For example, in some optional embodiments, the preset frequency is equal to 120 Hz. This can meet the display control requirements of the display panel with a display frequency of less than or equal to 120 Hz, so as to better balance the display effect and touch effect of the display panel.

[0053] In other examples, the preset frequency may also be set to 60 Hz, 90 Hz, 150 Hz, 180 Hz, etc. as needed.

[0054] In the embodiment of the present application, the display frequency of the display panel can be selected as needed, preferably 120 Hz, 60 Hz or 30 Hz, etc.

[0055] Optionally, taking the preset frequency as 120 Hz as an example, when the display panel is in the second display state, in some exemplary embodiments, the display frequency of the display panel may be 120 Hz.

[0056] For example, optionally, if the display frequency of the display panel is 120 Hz, the number of touch reporting signals located in the blank area in the second display state is at least one.

[0057] For example, in the second display state, touch detection can be performed on the display panel based on the second touch detection signal, and at least one touch reporting signal can be performed through at least one touch reporting signal of the second touch detection signal located in the blank area of ​​the second display control signal.

[0058] For example, refer to Figure 2 Example 1 shown in the figure shows a timing diagram of a display control signal and a touch detection signal of one example. The preset frequency is 120Hz, referring to Figure 2In the example 1 shown, the display frequency of the display panel can be a high display frequency of 120Hz, at which time the display control signal is the second display control signal, the touch detection signal is the second touch detection signal, and the display panel is in the second display state. In the embodiment of the present application, the display panel is controlled to enter the second display state for display according to the second display control signal, and each blank area of ​​the second display control signal can be set to perform touch detection on the display panel according to the second touch detection signal, and one touch reporting signal is performed through one touch reporting signal of the second touch detection signal. The second display control signal is only activated in the action area, and the second display control signal is not activated in the blank area, thereby avoiding the second display control signal and the second touch detection signal from acting at the same time, and can improve the undesirable phenomenon of water ripples caused by the mutual interference between the display control signal and the touch detection signal on the display panel, thereby improving the display effect of the display panel and improving the touch effect.

[0059] Therefore, through the above-mentioned optional embodiments, it is possible to adapt to the display requirements of the display panel at a higher display frequency of 120Hz, which is beneficial to perform touch detection on the display panel according to the touch detection signal and realize one touch reporting point in each blank area of ​​the second display control signal, thereby improving the undesirable phenomenon of water ripples on the display panel caused by mutual interference between the display control signal and the touch detection signal, and improving the display effect of the display panel. At the same time, the touch effect is effectively improved, thereby better taking into account the display effect and touch effect of the display panel.

[0060] Optionally, taking the preset frequency as 120 Hz as an example, when the display panel is in the first display state, in some exemplary embodiments, the display frequency of the display panel may be 60 Hz.

[0061] For example, optionally, if the display frequency of the display panel is 60 Hz, the number of touch reporting signals located in the blank area in the first display state is at least 2.

[0062] For example, in the first display state, touch detection can be performed on the display panel based on the first touch detection signal, and at least two touch reporting signals are performed through at least two touch reporting signals of the first touch detection signal located in the blank area of ​​the first display control signal.

[0063] For example, refer to Figure 2 Example 2 shown in the figure shows a timing diagram of a display control signal and a touch detection signal of one example. The preset frequency is 120Hz, referring to Figure 2In the example 2 shown, the display frequency of the display panel in this example can be a low display frequency of 60Hz, at which time the display control signal is the first display control signal, the touch detection signal is the first touch detection signal, and the display panel is in the first display state. In the embodiment of the present application, the display panel is controlled to enter the first display state for display according to the first display control signal, and each blank area of ​​the first display control signal can be set to perform touch detection on the display panel according to the first touch detection signal, and two touch reporting signals of the first touch detection signal are used to perform two touch reportings. The first display control signal is only activated in the action area, and the first display control signal is not activated in the blank area, thereby avoiding the first display control signal and the first touch detection signal from acting at the same time, and realizing multiple touch reportings, thereby increasing the frequency of touch reporting, and being able to improve the undesirable phenomenon of water ripples caused by the mutual interference between the display control signal and the touch detection signal on the display panel, and improving the display effect of the display panel, while effectively improving the touch effect.

[0064] Therefore, through the above-mentioned optional embodiments, it is possible to adapt to the display requirements of the display panel at a low display frequency of 60 Hz, which is beneficial to perform touch detection on the display panel and realize multiple touch reporting points according to the touch detection signal in each blank area of ​​the first display control signal, thereby improving the undesirable phenomenon of water ripples on the display panel caused by mutual interference between the display control signal and the touch detection signal, and improving the display effect of the display panel. At the same time, the touch effect is effectively improved, thereby better taking into account the display effect and touch effect of the display panel.

[0065] Optionally, taking the preset frequency of 120 Hz as an example, the display panel is in the first display state, and in other exemplary embodiments, the display frequency of the display panel may be 30 Hz.

[0066] For example, optionally, if the display frequency of the display panel is 30 Hz, the number of touch reporting signals located in the blank area in the first display state is at least 4.

[0067] For example, in the first display state, touch detection can be performed on the display panel based on the first touch detection signal, and at least four touch reporting signals of the first touch detection signal located in the blank area of ​​the first display control signal can be used to perform at least four touch reporting times.

[0068] For example, refer to Figure 2 Example 3 shown in the figure shows a timing diagram of the display control signal and the touch detection signal of one of the examples. The preset frequency is 120Hz, referring to Figure 2In the example 3 shown, the display frequency of the display panel in this example can be a low display frequency of 30Hz, at which time the display control signal is the first display control signal, the touch detection signal is the first touch detection signal, and the display panel is in the first display state. In the embodiment of the present application, the display panel is controlled to enter the first display state for display according to the first display control signal, and each blank area of ​​the first display control signal can be set to perform touch detection on the display panel according to the first touch detection signal, and four touch reporting signals of the first touch detection signal are used to perform four touch reportings. The first display control signal is only activated in the action area, and the first display control signal is not activated in the blank area, thereby avoiding the first display control signal and the first touch detection signal from acting at the same time, and realizing multiple touch reportings, thereby increasing the frequency of touch reporting, and being able to improve the undesirable phenomenon of water ripples caused by the mutual interference between the display control signal and the touch detection signal on the display panel, and improving the display effect of the display panel, while effectively improving the touch effect.

[0069] Therefore, through the above-mentioned optional embodiments, it is possible to adapt to the display requirements of the display panel at a low display frequency of 30 Hz, which is beneficial to perform touch detection on the display panel and realize multiple touch reporting points according to the touch detection signal in each blank area of ​​the first display control signal, thereby improving the undesirable phenomenon of water ripples on the display panel caused by mutual interference between the display control signal and the touch detection signal, and improving the display effect of the display panel. At the same time, the touch effect is effectively improved, thereby better taking into account the display effect and touch effect of the display panel.

[0070] It should be understood that the above descriptions are merely some optional embodiments of the embodiments of the present application and are not intended to be any limitation to the embodiments of the present application.

[0071] According to a second aspect of the present application, a display panel is provided, the display panel having a first display state, in which the display frequency of the display panel is less than a preset frequency, the touch reporting signal received by the display panel is located in a blank area of ​​the display control signal received by the display panel, and there are at least two touch reporting signals. It should be understood that the display control signal here can be the first display control signal.

[0072] Based on this, since the display panel has a first display state, and in the first display state, the display frequency of the display panel is less than the preset frequency, the touch point reporting signal received by the display panel is located in the blank area of ​​the display control signal received by the display panel, and there are at least two touch point reporting signals. Therefore, the touch point reporting of the display panel can be realized during the blank area of ​​the display control signal, thereby avoiding the mutual interference between the action of the display control signal and the touch point reporting of the touch detection signal, and there are at least two touch point reporting signals in the blank area of ​​the display control signal, thereby increasing the frequency of the touch point reporting. Therefore, the display panel can improve the adverse phenomenon of water ripples caused by mutual interference between the display control signal and the touch detection signal, and improve the display effect of the display panel, while effectively improving the touch effect. It can be seen that the display panel can better take into account both the display effect and the touch effect.

[0073] In the embodiment of the present application, the display panel can be any display panel with a touch function as long as it can meet the requirements. For example, in some optional application scenarios, the display panel can be an active matrix organic light emitting diode AMOLED display panel. The AMOLED display panel is a display panel with AMOLED (active matrix organic light emitting diode) material as the main material, which has the characteristics of faster response speed, higher contrast, wider viewing angle, strong outdoor readability and low power consumption.

[0074] It should be understood that since the display panel of the present solution is an AMOLED display panel, it can improve the adverse phenomenon of water ripples caused by the mutual interference between the display control signal and the touch detection signal of the AMOLED display panel, thereby improving the display effect of the AMOLED display panel and the touch effect at the same time.

[0075] In an embodiment of the present application, the display control signal may be a signal for performing display control on the display panel. It can affect the display effect of the display panel. In the present application, the display control signal may include a first display control signal and a second display control signal. By performing display control on the display panel according to the first display control signal, the display panel may enter a first display state, and in the first display state, the display frequency of the display panel is less than a preset frequency. By performing display control on the display panel according to the second display control signal, the display panel may enter a second display state, and in the second display state, the display frequency of the display panel is equal to a preset frequency. The blank area of ​​the display control signal may be a non-action time section of the display control signal, during which the display control signal does not act, and therefore performing touch reporting during this period avoids mutual interference with the display control signal.

[0076] For example, in the first display state, since the display frequency of the display panel is less than the preset frequency, the display panel will keep the picture without refreshing for a period of time when displaying the picture. At this time, the first display control signal does not act, and the refresh time is in the action area of ​​the first display control signal, and this period of non-refresh time is the blank area of ​​the first display control signal (for example, when the preset frequency is 120Hz, if the display panel has a display frequency of 30Hz, the first picture is refreshed and the next three pictures are kept, then the next three pictures are all in the blank area of ​​the first display control signal, and the first picture is in the action area). In addition, the blank area of ​​the first display control signal also includes the time segment when the first display control signal does not act between the adjacent picture refresh and picture keep. For example, in the second display state, since the display frequency of the display panel is equal to the preset frequency, the blank area of ​​the second display control signal is the time segment when the second display control signal does not act between the adjacent two picture refreshes.

[0077] In an embodiment of the present application, the touch detection signal may be a signal for performing touch detection on the display panel. In the present application, the touch detection signal may include a first touch detection signal and a second touch detection signal. The first touch detection signal is a touch detection signal for performing touch detection on the display panel in the first display state of the display panel. The second touch detection signal is a touch detection signal for performing touch detection on the display panel in the second display state of the display panel. The touch reporting signal may be a signal of the touch detection signal for reporting the result of the touch detection. For example, the display panel may be touch-detected according to the touch detection signal to determine the touch position information when the user's finger touches the display panel, and the touch position information may be reported as the result of the touch detection through the touch reporting signal to realize the touch reporting. For another example, if the touch position information when the user's finger touches the display panel is not detected, it may be reported as the result of the touch detection with no touch position information to realize the touch reporting.

[0078] In the embodiment of the present application, there are at least two touch reporting signals in the blank area of ​​the display control signal (here, the first display control signal). Therefore, at least two touch reporting signals can be performed in the blank area of ​​each first display control signal, thereby increasing the frequency of touch reporting signals and effectively improving the touch effect.

[0079] In some optional embodiments, the display panel also has a second display state, in which the display frequency of the display panel is equal to the preset frequency, and the touch reporting signal received by the display panel is located in the blank area of ​​the display control signal received by the display panel. It should be understood that the display control signal here can be a second display control signal.

[0080] Based on this, since in the second display state of the display panel, the display frequency of the display panel is equal to the preset frequency, the touch point reporting signal received by the display panel is located in the blank area of ​​the display control signal received by the display panel, so that the touch point reporting can be realized during the blank area of ​​the display control signal (second display control signal), thereby avoiding the mutual interference between the action of the display control signal (second display control signal) and the touch point reporting of the touch detection signal (second touch detection signal) in the second display state where the display frequency of the display panel is equal to the preset frequency, so that the display panel can further improve the adverse phenomenon of water ripples caused by mutual interference between the display control signal and the touch detection signal, thereby improving the display effect of the display panel and improving the touch effect.

[0081] Optionally, one or more touch reporting signals may exist in the blank area of ​​the display control signal (here, the second display control signal).

[0082] In some optional embodiments, the number of touch point reporting signals located in the blank area in the first display state is greater than the number of touch point reporting signals located in the blank area in the second display state.

[0083] Therefore, compared with the second display state of the display panel, the frequency of touch reporting of the display panel in the first display state can be increased in the present application. Since the display frequency of the first display state is lower than the display frequency of the second display state, the display effect and touch effect of the display panel at a lower display frequency can be better taken into account.

[0084] The specific number of touch reporting signals in the above two display states can be set as needed. For example, in an optional example, the number of touch signals located in a single blank area of ​​the first display control signal in the first display state is 2, and the number of touch signals located in a single blank area of ​​the second display control signal in the second display state is 1. In another optional example, the number of touch signals located in a single blank area of ​​the first display control signal in the first display state is 4, and the number of touch signals located in a single blank area of ​​the second display control signal in the second display state is 2. In yet another optional example, the number of touch signals located in a single blank area of ​​the first display control signal in the first display state is 4, and the number of touch signals located in a single blank area of ​​the second display control signal in the second display state is 2. The above examples are only used to facilitate the understanding of the embodiments of the present application and are not intended to limit the embodiments of the present application.

[0085] In the embodiment of the present application, the preset frequency can be set as needed, and no specific limitation is made here. For example, in some optional embodiments, the preset frequency is equal to 120 Hz. This can meet the display control requirements of the display panel with a display frequency of less than or equal to 120 Hz, so as to better balance the display effect and touch effect of the display panel.

[0086] In the embodiment of the present application, the display frequency of the display panel can be selected as needed, preferably 120 Hz, 60 Hz or 30 Hz, etc.

[0087] Optionally, taking the preset frequency as 120 Hz as an example, when the display panel is in the second display state, in some exemplary embodiments, the display frequency of the display panel may be 120 Hz.

[0088] For example, optionally, if the display frequency of the display panel is 120 Hz, the number of touch reporting signals located in the blank area in the second display state is at least one.

[0089] Therefore, through the above-mentioned optional embodiments, it is possible to adapt to the display requirements of the display panel at a higher display frequency of 120Hz, which is beneficial to perform touch detection on the display panel according to the touch detection signal and realize one touch reporting point in each blank area of ​​the second display control signal. Therefore, the display panel can improve the undesirable phenomenon of water ripples caused by mutual interference between the display control signal and the touch detection signal, improve the display effect of the display panel, and effectively improve the touch effect at the same time, thereby better taking into account the display effect and touch effect of the display panel.

[0090] Optionally, taking the preset frequency as 120 Hz as an example, when the display panel is in the first display state, in some exemplary embodiments, the display frequency of the display panel may be 60 Hz.

[0091] For example, optionally, if the display frequency of the display panel is 60 Hz, the number of touch reporting signals located in the blank area in the first display state is at least 2.

[0092] For example, in the first display state, touch detection can be performed on the display panel based on the first touch detection signal, and at least two touch reporting signals are performed through at least two touch reporting signals of the first touch detection signal located in the blank area of ​​the first display control signal.

[0093] Therefore, through the above-mentioned optional embodiments, it is possible to adapt to the display requirements of the display panel at a low display frequency of 60 Hz, which is beneficial to perform touch detection on the display panel and realize multiple touch reporting points according to the touch detection signal in each blank area of ​​the first display control signal. Therefore, the display panel can improve the undesirable phenomenon of water ripples caused by mutual interference between the display control signal and the touch detection signal, improve the display effect of the display panel, and effectively improve the touch effect at the same time, thereby better taking into account the display effect and touch effect of the display panel.

[0094] Optionally, taking the preset frequency of 120 Hz as an example, the display panel is in the first display state, and in other exemplary embodiments, the display frequency of the display panel may be 30 Hz.

[0095] For example, optionally, if the display frequency of the display panel is 30 Hz, the number of touch reporting signals located in the blank area in the first display state is at least 4.

[0096] Therefore, through the above-mentioned optional embodiments, it is possible to adapt to the display requirements of the display panel at a low display frequency of 30 Hz, which is beneficial to perform touch detection on the display panel and realize multiple touch reporting points according to the touch detection signal in each blank area of ​​the first display control signal. Therefore, the display panel can improve the undesirable phenomenon of water ripples caused by mutual interference between the display control signal and the touch detection signal, improve the display effect of the display panel, and effectively improve the touch effect at the same time, thereby better taking into account the display effect and touch effect of the display panel.

[0104] According to the display control scheme provided in the embodiment of the present application, the control unit 302 can control the display panel to enter the first display state for display according to the first display control signal. In the first display state, the display frequency of the display panel is less than the preset frequency. The detection unit 304 then performs touch detection on the display panel according to the first touch detection signal in the first display state, and the touch reporting signal of the first touch detection signal is in the blank area of ​​the first display control signal. In this way, the touch reporting of the first touch detection signal can be realized in the period of the blank area of ​​the first display control signal, thereby avoiding the mutual interference between the action of the first display control signal and the touch reporting of the first touch detection signal. In addition, there are at least two touch reporting signals in the blank area of ​​the first display control signal, thereby increasing the frequency of touch reporting. Therefore, the embodiment of the present application can improve the undesirable phenomenon of water ripples on the display panel caused by the mutual interference between the display control signal and the touch detection signal, and improve the display effect of the display panel, while effectively improving the touch effect. It can be seen that the technical scheme can better take into account the display effect and touch effect of the display panel with touch function.
