[0040] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0041] With the development of Active-Matrix Organic Light-Emitting Diode (AM-OLED) technology, more and more AM-OLED screen devices are being widely used in the market. Furthermore, to improve the user's visual experience, the refresh rate requirements for these screens are gradually increasing. Related technologies typically improve the screen refresh rate by driving the display at a higher frequency.

[0042] It's understandable that increasing the screen refresh rate will increase power consumption during use. Therefore, when improving the user's visual experience by increasing the screen refresh rate, the device's battery life must be considered.

[0043] In related technologies, a feature called "regional refresh" has been proposed for AM-OLED screens in terminals. This means that different display areas on the same terminal screen are driven at different frequencies, thus creating areas with different refresh rates. This feature is used in certain application scenarios, providing users with a better visual experience while also saving power on the terminal. For example, ... Figure 1A As shown. Figure 1A This is an application diagram illustrating a display screen with partitioned refresh functionality according to an exemplary embodiment. Figure 1A In the middle, terminal screen 101 ( Figure 1A The screen 101 (referred to as the display area of ​​screen 101) is a screen with a zoned refresh function. Normally, the entire screen 101 is driven at a consistent frequency, allowing it to display images to the user at a uniform refresh rate (e.g., the entire screen 101 displays images to the user at a relatively high refresh rate). However, when the terminal is running a short video application, to provide a better visual experience for the user while watching short videos, a higher refresh rate is typically set for the short video playback area, for example... Figure 1A The first region 102 in the image is typically driven at a higher frequency, allowing it to display the image to the user at a higher refresh rate. However, areas within the application interface that are not primarily used for playing short videos are usually set to a lower refresh rate to reduce power consumption. For example... Figure 1A The second region 103 is typically driven at a lower frequency, allowing it to display images to the user at a lower refresh rate. There is a dividing line between the display areas with higher refresh rates and those with lower refresh rates. For example... Figure 1A The dividing line 104 between the first region 102 and the second region 103.

[0044] However, because some transistors on the display screen are in a low refresh rate region during the activation of the partition refresh function, the following... Figure 1A In this embodiment, for the terminal screen 101, some areas of the screen are displayed at a high refresh rate at inconsistent times. Therefore, the thin-film transistors (TFTs) of the display screen may experience threshold voltage drift due to the positive bias temperature stress (PBTS) effect, resulting in abnormal screen display when the terminal screen returns to a uniform refresh rate. This is illustrated in example 1B. Figure 1B This is a schematic diagram illustrating an abnormal display on a screen with partitioned refresh functionality, according to an exemplary embodiment. Figure 1B In the middle, continuing Figure 1A Related embodiments. When the terminal is closed and running application A is on the desktop, the terminal screen 101 will display the image to the user at a consistent refresh rate (for example, the terminal screen 101 will display the image to the user at a higher refresh rate). However, in this case, the terminal's display screen will exhibit a display anomaly at the boundary line 104 where application A is running (for example,...). Figure 1B (The dashed part in the text).

[0045] To facilitate understanding, the causes of the above-mentioned display anomalies will be explained below from the perspective of the pixel driving circuit of the terminal screen. Figure 1C This is a schematic diagram of an OLED screen pixel circuit according to an exemplary embodiment. Figure 1D This is a circuit timing diagram illustrated according to an exemplary embodiment. Wherein, Figure 1D express Figure 1C The timing sequence for writing pixel data into frames in the pixel circuit.

[0046] exist Figure 1C In this context, the process of writing pixel data into a frame can be divided into four stages (i.e., corresponding to...). Figure 1D The process involves four stages: A, B, C, and D. When the electromagnetic (EM) signal is at a high level, it enters the first stage (corresponding to...). Figure 1D In stage A of the process, Pscan2 is at a low level, transistors T8 and T7 are turned on, resetting the source of driving transistor T1, and simultaneously, the Vi2 signal is written to node N3 to reset the OLED anode. In the second stage (corresponding to...)... Figure 1DIn stage B of the process, Nscan1 and Nscan2 go high sequentially, and the Vi1 signal is written to nodes N1 and N3 sequentially, resetting the gate and drain of the driving transistors. In the third stage (corresponding to...)... Figure 1D In stage C, Pscan1 is low, transistor T2 is on, and the Data signal is written to node N1 by transistors T1 and T3. In stage four (i.e., corresponding to...) Figure 1D In the middle D stage, Pscan2 is at a low level, the Vi3 signal is written to node N2 again and then to node N3 through T1, resetting both nodes. Afterwards, the EM signal goes low, and the OLED device emits light. Figure 1C In the diagram, T1, T2, T3, T4, T5, T6, T7, and T8 represent transistors in the pixel circuit. Figure 1C In this context, Pscan refers to the scanning signal used to control pixels (e.g., ...). Figure 1C In this context, Pscan1 and Pscan2 are used, and Nscan refers to auxiliary control signals (e.g., Pscan1 and Pscan2). Figure 1C In the figure, Nccan1 and Nccan2), Cst represents the capacitance.

[0047] Correspondingly, when the terminal screen is at a lower refresh rate, the pixel circuit writes hold frame data, and the driving timing is as follows: Figure 1E As shown. Figure 1E This is a circuit timing diagram illustrated according to an exemplary embodiment. Wherein, Figure 1E and Figure 1D The main difference lies in stages B and C, where the high level of Nscan1 and Nscan2 and the low level of Pscan1 are removed respectively, reducing the frequency of switching between high and low levels of the corresponding signals, thereby reducing the power consumption of the mobile phone display.

[0048] Because the duration of the high gate potential of transistors T3 and T4 differs under high and low refresh rate conditions (reflected in stages B and C of the timing diagram), transistors T3 and T4 are affected by PBTS, resulting in electrical drift and causing changes in the screen display. This manifests as an increase or decrease in brightness in the corresponding pixel areas, and this difference becomes increasingly pronounced as the testing time continues. Therefore, after displaying in partitioned refresh mode for a certain period of time, a visual effect such as... Figure 1B The described display anomaly.

[0049] To address the aforementioned technical problems, this disclosure proposes an application display control method. By adjusting the refresh rate of higher refresh rate areas and / or lower refresh rate areas during the operation of the target application, the visual position of the higher refresh rate area corresponding to the display screen is "expanded" or "shrunken," thereby reducing the degree to which the screen display device is affected by PBTS when the screen display area adopts the partitioned refresh display function, and thus alleviating the phenomenon of abnormal screen display.

[0050] It should be noted that, in some embodiments, the terminal includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0051] For ease of understanding, the embodiments disclosed herein will be described using mobile phone type terminals as relevant examples.

[0052] Figure 2A This is a flowchart illustrating an application display control method according to an exemplary embodiment, such as... Figure 2A As shown, the application display control method is used in the terminal, including the following steps.

[0053] In step S11, in response to running the target application, a first interface of the target application is displayed on the display screen. The first interface includes a first area and a second area. The first area is driven at a first frequency, and the second area is driven at a second frequency. The first frequency is higher than the second frequency.

[0054] In step S12, in response to the fulfillment of the first condition, a portion or all of the second region is driven at a third frequency, and / or a portion or all of the first region is driven at a fourth frequency.

[0055] Among them, the third frequency is higher than the second frequency, and the fourth frequency is lower than the first frequency.

[0056] In this embodiment of the disclosure, since the first interface displayed on the screen, where the target application is running, includes a first region driven at a first frequency and a second region driven at a second frequency, and the first frequency is higher than the second frequency, the first interface is an interface driven by different frequencies. When a first condition is met, driving a portion or all of the second region at a third frequency, and / or driving a portion or all of the first region at a fourth frequency, allows for adjustment of corresponding areas of the first region and / or the second region in the first interface. This reduces the impact on the lifespan of the display screen caused by the first region and / or the second region being displayed in a fixed position.

[0057] In some embodiments, terms such as "frequency", "display frequency", "drive frequency", "refresh rate", "screen refresh rate", and "image refresh rate" can be used interchangeably to characterize the number of times the electron beam scans the screen image within a specified time.

[0058] In some embodiments, the terms "drive", "start", "run", and "display" can be used interchangeably.

[0059] Specifically, driving the first region at the first frequency can be understood as displaying the image in the first region at the first refresh rate. Driving the second region at the second frequency can be understood as displaying the image in the second region at the second refresh rate, and so on. Further details will not be elaborated here.

[0060] It should be noted that the target application may be one that requires different frequencies to be used to drive different areas of the terminal display screen during operation in order to display the image.

[0061] Running the target application can be understood as the application starting up based on the obtained execution instructions. Displaying the first interface of the running target application on the screen can be understood as the screen displaying the content of the target application during its operation.

[0062] For example, continuing Figure 1A The relevant embodiments are described in... Figure 1A In this embodiment, the interface displayed on the terminal screen 101 can be considered as the first interface of the actual target application running. The area in the first interface where a short video (i.e., the animal image in the figure) is played can be considered as the first area 102, and the area in the first interface where no short video is played can be considered as the second area 103.

[0063] In some embodiments, the first condition may be met, for example, the time condition for displaying the first interface on the display screen.

[0064] For example, satisfying the first condition includes: detecting that the time for which the display screen shows the first interface is greater than or equal to a first duration. That is, in response to detecting that the time for which the display screen shows the first interface is greater than or equal to the first duration, it is determined that the first condition is satisfied.

[0065] It's understandable that the position of the display screen corresponding to the first area in the first interface usually won't change. For example, continuing... Figure 1A Example. The first region 102 in the first interface typically does not change (e.g., the resolution of the display area typically does not change in the current interface). In this case, monitoring the time the first interface is displayed on the display screen can be understood as monitoring the holding time of the first region and the second region on the display screen.

[0066] However, if an interface switch occurs during the monitoring period, for example, switching to a second interface, where the first area in the second interface corresponds to a different area on the display screen than the first area in the first interface. For example, let's take... Figure 2B For example, Figure 2B This is a schematic diagram illustrating a scenario where a display screen shows a second interface according to an exemplary embodiment. For example... Figure 2B As shown, combined with Figure 1A In a related embodiment, the first area 102 in the second interface corresponds to a different area of ​​the display screen than the first area 102 in the first interface (the first area 102 in the second interface corresponds to a larger area of ​​the display screen compared to the first area 102 in the first interface). In this case, it is necessary to reset the monitoring time of the first interface to zero and then re-monitor the time when the second interface is displayed on the display screen.

[0067] When the target application is running, the display screen switches from the first interface to the second interface, and the frequency can be adjusted in the following ways. Figure 2C This is a flowchart of an application display control method proposed in an embodiment of this disclosure, such as... Figure 2C As shown, it includes the following steps.

[0068] In step S21, in response to the target application's running interface switching from the first interface to the second interface, the time for the display screen to display the second interface is monitored.

[0069] In step S22, if the time for which the second interface is displayed on the screen is greater than or equal to the second duration, the frequency of a portion or all of the second area of ​​the second interface is adjusted to the third frequency, and / or the frequency of a portion or all of the first area of ​​the second interface is adjusted to the fourth frequency.

[0070] The first area in the second interface is different from the area on the screen corresponding to the first area in the first interface.

[0071] In this embodiment of the disclosure, when it is determined that the interface on the display screen switches from a first interface to a second interface, the screen area corresponding to the first area in the second interface is different from the screen area corresponding to the first area in the first interface. Therefore, the screen area corresponding to the first area is considered to have changed when switching from the first interface to the second interface. In this case, the duration of the second interface displayed on the display screen is re-monitored to reduce the possibility that the frequency of adjustment of the second area and / or the first area in the second interface is too frequent due to the influence of the monitoring time during the display screen displaying the first interface.

[0072] In some embodiments, a portion or all of the second region may be a region consisting of one or more rows of pixels and / or a region consisting of one or more columns of pixels. A portion or all of the first region may be a region consisting of one or more rows of pixels and / or a region consisting of one or more columns of pixels.

[0073] For ease of understanding, the following description will use an example of a second region consisting of one or more rows of pixels. It is understood that the exemplary descriptions of the first region are also applicable to the embodiments of this disclosure.

[0074] Figure 3A This is a flowchart illustrating an application display control method according to an exemplary embodiment. For driving a portion or all of the second region at a third frequency, it can be achieved in the following manner.

[0075] In step S31, the second region is determined.

[0076] In step S32, the frequency of the region containing N rows of pixels in the second region is adjusted to the third frequency, where N is an integer greater than or equal to 1.

[0077] Where N is an integer greater than or equal to 1.

[0078] In this embodiment of the disclosure, by adjusting the frequency of N rows of pixels in the second region from the second frequency to the third frequency, the frequency of a portion or all of the second region can be adjusted, thereby reducing the impact on the lifespan of the display screen caused by the first region and / or the second region in the first interface being displayed in a fixed position.

[0079] It should be noted that, for Figure 2A , Figure 2B , Figure 2C as well as Figure 3A The relevant embodiments have been described in detail above, and the combined implementations will not be repeated here.

[0080] It should be noted that if the second region contains P rows of pixels, where P is an integer greater than N, then adjusting the frequency of N rows of pixels in the second region from the second frequency to the third frequency means adjusting the frequency of a portion of the second region. If the second region contains N rows of pixels, then adjusting the frequency of N rows of pixels in the second region from the second frequency to the third frequency means adjusting the frequency of the entire second region.

[0081] For example, with Figure 3B For example, Figure 3B This is an exemplary embodiment illustrating an application diagram for adjusting the frequency of a portion of a second region.

[0082] like Figure 3B As shown, continuing Figure 1B In this embodiment, the frequency corresponding to the first region 102 is the first frequency, and the frequency corresponding to the second region 103 is the second frequency. The region 201 between the dashed and solid lines represents the N rows of pixels corresponding to the adjusted portion of the second region.

[0083] It should be noted that the third frequency can be equal to the first frequency, or it can be higher than the second frequency but lower than the first frequency. Similarly, the fourth frequency can be equal to the second frequency, or it can be higher than the second frequency but lower than the first frequency.

[0084] In some embodiments, the region corresponding to the N rows of pixels may be, for example, the N rows of pixels adjacent to the first region in the second region, or other specified N rows of pixels.

[0085] It is understood that driving part or all of the first region with the fourth frequency can also be implemented in a manner similar to steps S31 to S32.

[0086] For example, given a first region, the frequency of the region containing Q rows of pixels in the first region is adjusted to a third frequency, where Q is an integer greater than or equal to 1. Q and N may or may not be equal.

[0087] In some embodiments, Figure 3A Related embodiments can be compared with Figure 2A , Figure 2B as well as Figure 2C One or more related embodiments may be implemented in combination.

[0088] It is understandable that the process of adjusting the frequency of a portion or all of the second region to the third frequency can be implemented in multiple steps. For example, each adjustment can be based on a set step size, and a further adjustment with a different step size can be performed after a certain period of time.

[0089] For example, with Figure 4 For example, Figure 4 This is a flowchart illustrating an application display control method according to an exemplary embodiment, including the following steps.

[0090] In step S41, the frequency of the region containing the N rows of pixels in the second region is determined to be the time of the third frequency.

[0091] In step S42, in response to the fact that the frequency of the region containing the N rows of pixels in the second region is greater than or equal to the third frequency for a period of time, the frequency of the region containing the N+M rows of pixels is adjusted to the third frequency.

[0092] Where M is an integer greater than or equal to 1.

[0093] It is understood that driving part or all of the first region at the fourth frequency can also be implemented in a manner similar to steps S41 to S42.

[0094] For example, when the frequency of the region containing the Q rows of pixels in the first region is determined to be the third frequency, in response to the time when the frequency of the region containing the Q rows of pixels in the first region is the fourth frequency being greater than or equal to the fifth duration, the frequency of the region containing the Q+O rows of pixels is adjusted to the third frequency. Here, O is an integer greater than or equal to 1, O and M can be equal or not equal, and the fifth duration and the first duration can be equal or not equal.

[0095] In this embodiment, after adjusting the frequency of the region containing N rows of pixels, subsequent frequency adjustments are performed with M rows of pixels as the step size. This ensures a smooth frequency adjustment process and reduces the possibility of a degraded user visual experience due to an unstable adjustment process. Furthermore, by limiting the interval between adjustments, the possibility of a degraded user visual experience due to overly frequent adjustments can be reduced, and the possibility of abnormal screen display due to excessively large intervals between adjustments can also be reduced.

[0096] It should be noted that setting a step size can be understood as setting a distance of N pixels per move, where N is an integer greater than or equal to 1. The step size can be the system default or a user-defined step size.

[0097] In some embodiments, Figure 4 Related embodiments can be compared with Figure 2A , Figure 2B , Figure 2C as well as Figure 3A One or more related embodiments may be implemented in combination.

[0098] In some scenarios, for a display screen, in addition to the first area and the second area, there is also a frequency transition area between the first frequency and the second frequency, namely the third area.

[0099] For display screens that include a third area, the following methods can be used for application display control. Figure 5 This is a flowchart illustrating an application display control method according to an exemplary embodiment. For example... Figure 5 As shown, the method includes the following steps.

[0100] In step S51, the third region is determined.

[0101] In step S52, the frequency of a portion or all of the third region is adjusted to the third frequency, and / or the frequency of a portion or all of the third region is adjusted to the fourth frequency.

[0102] The target application's interface includes a third region, which is the area between the first and second regions. The frequency corresponding to the third region is the fifth frequency, which is higher than the second frequency but lower than the first frequency.

[0103] In this embodiment, by adjusting the frequency of a portion or all of the third region, the edge position of the first region can be adjusted. This reduces the possibility that the first region and / or the second region in the first interface would be displayed in a fixed position, thus affecting the lifespan of the display screen.

[0104] In some embodiments, Figure 5 Related embodiments can be compared with Figure 2A , Figure 2B , Figure 2C , Figure 3A as well as Figure 4 One or more related embodiments may be implemented in combination.

[0105] It is understood that the above embodiments describe a scheme for frequency adjustment of the second region. However, in order to reduce the possibility of a decrease in user visual experience due to changes in the display interface after adjustment, a corresponding frequency restoration scheme is also required after the adjustment.

[0106] For example, Figure 6 This is a flowchart illustrating an application display control method according to an exemplary embodiment. For example... Figure 6 As shown, the method includes the following steps.

[0107] In step S61, the time when a portion or all of the second region is driven at a third frequency is monitored, and / or the time when a portion or all of the first region is driven at a fourth frequency is monitored.

[0108] In step S62-1, if the time for driving part or all of the second region with the third frequency is greater than or equal to the third duration, then the frequency of the part of the second region is restored to the second frequency.

[0109] In step S62-2, if the time for driving part or all of the first region at the fourth frequency is greater than or equal to the fourth duration, then the frequency of the part of the first region is restored to the first frequency.

[0110] In this embodiment, the time of the area in the second region that has been adjusted to the third frequency is monitored, and the frequency corresponding to the area whose time meets the duration requirement is restored to the second frequency. This reduces the possibility of a decrease in user visual experience due to changes in the adjusted display interface, and also reduces the impact on the lifespan of the display screen caused by excessively frequent restorations.

[0111] It should be noted that the time during which a portion or all of the second region is driven at the third frequency can be understood as the time during which pixels in a portion or all of the second region remain active at the third frequency. Similarly, the time during which a portion or all of the first region is driven at the fourth frequency can be understood as the time during which pixels in a portion or all of the first region remain active at the fourth frequency.

[0112] In summary, in this embodiment of the present disclosure, by adjusting different frequencies to adjust the position of the boundary line between the corresponding display areas, the degree of influence of PBTS on the pixels of the terminal display screen can be reduced, thereby reducing display abnormalities on the terminal display screen and improving the visual experience of the user.

[0113] Based on the same concept, embodiments of this disclosure also provide an application display control device.

[0114] It is understood that the application display control device provided in this disclosure includes hardware structures and / or software modules corresponding to each function in order to achieve the above-mentioned functions. In conjunction with the units and algorithm steps of the various examples disclosed in this disclosure, this disclosure can be implemented in hardware or a combination of hardware and computer software.
