Obviously, the accompanying drawings described below are only some embodiments of this disclosure. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0043] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0044] The terms "first," "second," etc., used in the embodiments of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices. Additionally, the use of "and / or" in this application indicates at least one of the connected objects, such as A and / or B and / or C, representing seven possibilities: including A alone, B alone, C alone, both A and B present, both B and C present, both A and C present, and A, B, and C present.

[0045] In related technologies, the time required for pixel charging is fixed. To improve the display effect, the embedded touch display panel needs to have a sufficiently high screen refresh rate. Correspondingly, the duration of the screen display sequence also increases. To improve touch accuracy, a sufficiently high touch sampling frequency is required. Correspondingly, the duration of the touch sampling sequence also needs to increase.

[0046] The display timing and touch scanning timing of an embedded touch display panel conflict, which limits both the display effect and the accuracy of touch sampling.

[0047] This disclosure provides a display control method applied to a display device, which may be a laptop computer, a smart all-in-one computer, or other display devices. The display device includes a display panel, and the display panel is specifically an embedded touch display panel.

[0048] Step 101: Obtain the display refresh rate of the display device.

[0049] In this embodiment, the display device can provide different display refresh rates during use. Specifically, in one embodiment, the display refresh rate includes a first refresh rate and a second refresh rate, wherein the first refresh rate is greater than the second refresh rate.

[0050] It should be understood that in the technical solution of this embodiment, the display refresh rate of the display device is adjustable to meet the different requirements of the display refresh rate of the display device under different usage conditions.

[0051] For example, when users play shooting games, they have high requirements for the real-time performance of the screen display. The display device operates in a non-touch display mode, which corresponds to a high display refresh rate. For example, the display refresh rate can be 180Hz.

[0052] For example, when a user watches a high-definition video, they have higher requirements for picture quality and a higher display refresh rate. At the same time, the user may perform operations such as pause and resume via touch. In this case, the display device operates in the third touch display mode mentioned above. In this operating mode, the display device supports touch function and has a relatively high display refresh rate. For example, the display refresh rate can be 120Hz.

[0053] For example, when a user is browsing a webpage normally, the display refresh rate can be 90Hz, and the touch sampling frequency can be [missing information].

[0054] For example, when a user draws using the handwriting function, the screen is basically static. In this working mode, a lower display refresh rate is sufficient to meet the usage requirements. For example, the display refresh rate could be 60Hz.

[0055] It should be understood that the above display refresh rate is for illustrative purposes only, and its specific value is not limited to this.

[0056] Step 102: Determine the touch sampling frequency corresponding to the display panel based on the display refresh rate.

[0057] In this embodiment, different touch sampling frequencies are provided based on the different needs of users for touch functions.

[0058] The touch sampling frequency includes a first sampling frequency corresponding to a first refresh frequency and a second sampling frequency corresponding to a second refresh frequency, wherein the second sampling frequency is greater than the first sampling frequency.

[0059] like Figure 2 As shown, for example, when a user is playing a shooting game, the display refresh rate is 180Hz. At this time, the user does not need to perform touch operations, and the corresponding touch sampling frequency is 0.

[0060] For example, in the third touch display mode for users watching high-definition videos, the display refresh rate can be 120Hz, and the user may need to use the touch function, with a corresponding touch sampling frequency of 60Hz.

[0061] For example, in the second touch display mode when the user is browsing a webpage normally, the display refresh rate can be 90Hz and the touch sampling frequency can be 90Hz, which balances image quality and touch sampling effect.

[0062] For example, in the first touch display mode where the user draws using the handwriting function, the display refresh rate can be 60Hz. However, the drawing process has higher requirements for the real-time performance and accuracy of touch handwriting sampling. Therefore, setting the touch sampling frequency to 120Hz can significantly improve the touch sampling precision and accuracy, thereby helping to more accurately reproduce the touch handwriting.

[0063] It should be understood that the above display refresh rate is for illustrative purposes only, and its specific value is not limited to this.

[0064] Step 103: Drive the display panel to display images according to the determined display refresh rate, and collect touch information according to the touch sampling frequency.

[0065] After determining the display refresh rate and touch sampling rate, the display panel displays images according to the determined display refresh rate, and touch information is collected according to the determined touch sampling rate, so as to obtain a display effect and touch display effect that meet the usage requirements.

[0066] like Figure 1 As shown, in one embodiment, before step 101, the method further includes: obtaining the operating mode of the display device.

[0067] Accordingly, step 101 specifically includes: obtaining the display refresh rate corresponding to the working mode.

[0068] In the technical solution of this embodiment, the display device has a variety of different working modes. In one embodiment, the display device has two working modes: non-touch display mode and touch display mode. In the non-touch display mode, the touch function of the display panel is turned off, while in the touch display mode, the display panel supports touch function.

[0069] In this embodiment, the operating mode of the display device can be determined in different ways.

[0070] In one exemplary embodiment, a corresponding working mode can be selected based on the user's input.

[0071] Using a laptop or personal computer as an example, the user can switch the working mode of the display panel through specific physical or virtual buttons, or switch the working mode of the display panel through a designated control menu using a mouse, keyboard, etc. The user can also provide the above operation input through other means such as voice control, remote control, touchpad, etc.

[0072] When the type of display device changes, adaptive adjustments can be made as needed. For example, for some mobile phones or tablets, whose control relies on touch input, different operating modes corresponding to the touch display input can be selected via touch.

[0073] In some embodiments, obtaining the operating mode of the display device includes:

[0074] The display device is confirmed to be in non-touch display mode if any of the following conditions are met:

[0075] Operation input based on the first type of peripheral was detected;

[0076] Received input to disable touch functionality;

[0077] A first-type application was detected to be running.

[0078] In some embodiments, the first type of peripheral includes one or more of a mouse, keyboard, and gaming peripherals.

[0079] In one exemplary embodiment, the display device is a laptop computer. When the user operates based on a mouse and keyboard, the possibility of using the touch function at the same time is relatively small. Therefore, in this case, the working mode of the display device can be switched to a non-touch display mode.

[0080] Similarly, when a user uses a game controller, or game emulator peripherals such as a steering wheel or sensor gun, the likelihood of the user using the touch function is relatively small. In this case, it can be determined that the electronic device is operating in a non-touch display mode.

[0081] In some other embodiments, users can actively disable the touch function based on operation input, thereby entering a non-touch display mode.

[0082] In other embodiments, the likelihood of a user using touch functionality is also relatively low when a specific first-type application is running. For example, when a user is playing a game or watching high-definition video, the requirements for display quality are high, necessitating a high refresh rate, while the likelihood of needing touch functionality is relatively low. In some embodiments, the first-type application includes one or more of a game program and a video player. Thus, when the display device runs these first-type applications, it enters a non-touch display mode.

[0083] In some embodiments, obtaining the operating mode of the display device includes:

[0084] The operating mode of the display device is confirmed to be touch display mode if any of the following conditions are met:

[0085] Active stylus detected to be in working condition;

[0086] Received input to enable touch functionality;

[0087] The camera detects touch input actions;

[0088] A second type of application was detected to be running.

[0089] In the technical solution of this embodiment, if the active stylus is detected to be in working state, the user is likely to work based on the active stylus, and the user will inevitably use the touch function when using the active stylus.

[0090] In some other embodiments, a camera can be used to confirm whether a user has performed a touch operation based on image recognition.

[0091] It should be understood that if the display device is in a non-touch display mode, the touch operation performed cannot be recognized by the display panel. Therefore, in this embodiment, the touch input action needs to be captured by the camera to activate the working mode corresponding to the touch display mode.

[0092] In some embodiments, the operation input for enabling the touch function can not only refer to the above embodiments, but can also be implemented through gesture commands. For example, when the camera captures a specific gesture, the display panel is controlled to enter the touch display mode.

[0093] In some embodiments, determining whether to enter the touch display mode can be done by judging whether a second type of application is running. In some embodiments, the second type of application includes one or more of a document processing program and a drawing program.

[0094] It's important to understand that both types of applications, including games and other games, can be categorized as either type 1 or type 2. For example, shooting or action games, which require high real-time screen refresh rates and typically don't require touch input, can be identified as corresponding to a non-touch display mode. Conversely, games with lower performance requirements, such as puzzle games, can be identified as belonging to the second type of application. During implementation, the application's type should be determined based on factors such as hardware performance requirements, display needs, and input habits.

[0095] For example, when using a drawing program, touch input is more convenient; in this case, the user should enter the working mode corresponding to the touch display mode. Similarly, when using functions such as slideshows or document presentations, the background is relatively static, and the user may also input annotations or markings by hand. In this case, the requirement for screen refresh rate is relatively low, while the requirement for touch recognition is relatively high. Based on this requirement, the corresponding working mode can be determined.

[0096] In some embodiments, the operating modes include a non-touch display mode corresponding to a first refresh rate and a touch display mode corresponding to a second refresh rate.

[0097] In some embodiments, the first sampling frequency is 0, the first refresh frequency is greater than 0, and the operating timing of the display device includes multiple sequentially set screen refresh periods. One frame of the display device's operating timing corresponds to one screen refresh frame. This can be understood as disabling the touch sampling function of the display panel in this case.

[0098] In non-touch display mode, the display device can reach the highest display refresh rate. In this case, the display refresh rate corresponding to the non-touch display mode is the first refresh rate, and the touch sampling frequency corresponding to the non-touch display mode is the first sampling frequency.

[0099] In another embodiment, the working mode includes multiple touch display modes corresponding to different display refresh rates. Specifically, the touch sampling frequency is greater than 0, the display refresh rate is greater than 0, and the working time sequence of one frame of the display device includes alternating screen refresh period and touch scanning period. All screen refresh periods in the working time sequence of one frame of the display device correspond to one screen refresh frame.

[0100] For example, multiple touch display modes can be a low refresh rate mode with a lower display refresh rate and a high refresh rate mode with a higher display refresh rate.

[0101] It should be understood that the display panel may also include a greater number of operating modes. For example, the display panel may include three operating modes with different display refresh rates. For instance, the operating modes can be referred to as low power mode, balanced mode and high performance mode according to the display refresh rate from low to high.

[0102] It should be understood that the naming is not limited to this. For example, low power mode can also be called energy saving mode, and high performance mode can also be called game mode, etc.

[0103] It should be understood that the number of working modes of this display panel is not limited to this; the number can be further increased, for example, by setting four, five, six, or even more working modes. No further limitations or descriptions are provided here.

[0104] In some other embodiments, the two methods described above can be combined. Specifically, the display panel may include a touch display mode with touch function enabled and a non-touch display mode with touch function disabled. Both the touch display mode and the non-touch display mode may include multiple different numbers of working modes with different display refresh rates.

[0105] For example, the touch display mode includes three operating modes with different display refresh rates, and the non-touch display mode also includes three sub-operating modes with different display refresh rates. In this case, the display panel can be understood to include six different operating modes.

[0106] During implementation, the number of sub-working modes corresponding to both touch display mode and non-touch display mode can be adjusted, and the number is not limited to this.

[0107] In one embodiment, the display panel's operating modes specifically include a non-touch display mode, a first touch display mode, a second touch display mode, and a third touch display mode, thus the display panel includes a total of four operating modes. This embodiment is used as an example for illustration.

[0108] In non-touch display mode, each frame's working sequence consists of multiple consecutively set screen refresh periods, and each frame's working sequence corresponds to one screen refresh frame.

[0109] In touch display mode, the working time sequence of one frame of the display device includes alternating screen refresh time period and touch scan time period, and all screen refresh time periods in the working time sequence of one frame of the display device correspond to one screen refresh frame.

[0110] Furthermore, in some embodiments, in the touch display mode, in the first touch display mode and the second touch display mode, the duration ratio of the screen refresh period and the touch scan period in each frame working sequence of the display device is not equal.

[0111] In the technical solution of this embodiment, in the non-touch display mode, the first sampling frequency corresponding to touch sampling recognition is 0, in other words, touch sampling is in the off state.

[0112] In touch display mode, the working sequence of the display panel includes a screen refresh period and a touch scan period, which are set alternately.

[0113] In the technical solution of this embodiment, under the touch display mode, the ratio of screen refresh time period to touch scan time period is different in different specific working modes.

[0114] like Figure 2 As shown, the time sequence between two adjacent dashed lines represents one frame of operation corresponding to 180Hz. In the figure, D represents the duration of one screen refresh unit, and T represents the duration of one touch scan unit. The example is that the duration of the touch scan unit is equal to the duration of the screen refresh unit.

[0115] Figure 2 The first timing diagram in the middle corresponds to the non-touch display mode. The working timing of this frame includes 8 screen refresh unit durations set in sequence. These 8 screen refresh time periods correspond to one screen refresh frame.

[0116] For example, in the third touch display mode for users watching high-definition videos, the display refresh rate can be 120Hz, the touch sampling frequency is 60Hz, and the duration ratio of the screen refresh period to the touch scanning period is 2:1.

[0117] Specifically, in the third touch display mode, one frame of operation consists of 12 units of duration. One screen refresh period corresponds to two screen refresh units of duration, and one touch scan period corresponds to one touch scan period. In other words, for every two units of screen refresh, one unit of touch scan is performed. Every eight units of duration correspond to one screen refresh frame or touch scan frame, so the display refresh rate can be 120Hz, and the touch sampling frequency is 60Hz.

[0118] like Figure 2 As shown in the second timing diagram, for example, in the second touch display mode when the user is browsing a webpage normally, the display refresh rate can be 90Hz, the touch sampling frequency is 90Hz, and the duration ratio of the screen refresh period to the touch scanning period is 1:1.

[0119] Specifically, a frame's working sequence includes 16 units of duration. One screen refresh period corresponds to one screen refresh unit of duration, and one touch scan period corresponds to one touch scan unit of duration. In other words, for every unit of screen refresh, one unit of touch scan is performed.

[0120] like Figure 2 As shown in the third timing diagram, for example, in the first touch display mode where the user draws using the handwriting function, the display refresh rate can be 60Hz, the touch sampling frequency is 120Hz, and the duration ratio of the screen refresh period to the touch scanning period is 1:2.

[0121] Specifically, a frame working sequence includes 24 units of duration. In this embodiment, one screen refresh period corresponds to one screen refresh unit of duration, and one touch scan period corresponds to two touch scan unit of duration. That is to say, for every unit of screen refresh, two units of touch scan are performed.

[0122] Obviously, during implementation, the ratio of screen refresh time to touch scan time can be adjusted as needed, and its value is not limited to this.

[0123] In some embodiments, each frame working sequence includes a screen refresh period corresponding to a screen refresh frame, and each frame working sequence includes a touch scan period corresponding to m touch scan frames, where m is an integer or decimal greater than 0.

[0124] For example, the ratio of screen refresh time period to touch scan time period is 1:1.5. Each frame of working sequence corresponds to one screen refresh frame, so two frames of working sequence correspond to three touch scan frames.

[0125] Taking a display panel with 1600 display scan lines and 1600 touch scan lines as an example, in the above non-touch display mode, the maximum rated display refresh rate of the display panel under normal working conditions is 180Hz, then the display scan line scanning time is 1 (second) / 180 (Hz) / 1600 (lines) = 3.47 microseconds.

[0126] The 3.47 seconds can be understood as the shortest scanning time that the display panel's scan lines (specifically display scan lines or touch scan lines) can achieve, which corresponds to the aforementioned unit duration.

[0127] In other words, the scanning time for each display scan line or touch scan line is 3.47 microseconds. Thus, when the screen refresh rate is 120Hz, the touch scan frequency is 60Hz, and when the screen refresh rate is 90Hz, the touch scan frequency is 90Hz.

[0128] In this way, when it is necessary to improve the screen refresh rate or screen display quality, a working mode with a higher screen refresh rate can be selected, while when performing tasks such as handwriting recognition that require high accuracy in touch sampling, a working mode with a higher touch sampling frequency can be selected.

[0129] In some embodiments, when the display refresh rate of the display device is in the first refresh rate range, the display device corresponds to the first touch display mode; when the display refresh rate of the display device is in the second refresh rate range, the display device corresponds to the second touch display mode. The first refresh rate range and the second refresh rate range do not overlap.

[0130] like Figure 3 As shown, in the technical solution of this embodiment, when each frame of image is received, it can first detect whether it is in touch display mode. In this embodiment, the touch state can be represented by the identifier stored in the touch register. For example, if the identifier EN=0, it corresponds to non-touch display mode. At this time, the display is scanned according to the display refresh rate corresponding to the signal provided by the data source (e.g., graphics card) to display the image. In this case, the refresh rate of the display panel can be increased to the highest state as needed to provide the best display effect.

[0131] If the identifier EN=1, it corresponds to a non-touch display mode. In this case, the corresponding refresh rate can be determined based on the signal provided by the data source.

[0132] For example, if the screen refresh rate F of the signal provided by the data source is less than or equal to 60Hz, the touch sampling frequency X is determined to be 120Hz; if the screen refresh rate F of the signal provided by the data source is greater than 60Hz and less than or equal to 90Hz, the touch sampling frequency X is determined to be 90Hz; if the screen refresh rate F of the signal provided by the data source is greater than 90Hz and less than or equal to 120Hz, the touch sampling frequency is determined to be 60Hz. Then, image display and touch recognition are performed based on the display refresh rate and touch sampling frequency.

[0133] The above-mentioned frequencies of less than or equal to 60Hz, greater than 60Hz and less than or equal to 90Hz, and greater than 90Hz and less than or equal to 120Hz are the determined different display refresh rate ranges.

[0134] It should be understood that the above values ​​are for illustrative purposes only and are not limited thereto.

[0135] This disclosure provides a display device, which includes a display panel.

[0136] In some embodiments, the display device 400 includes:

[0139] The control module 403 is used to drive the display device to display an image according to the determined display refresh frequency, and to collect touch information according to the touch sampling frequency.
