Description

Technical Field

[0001] The present disclosure relates to the field of OLED burn-in prevention, and particularly includes a burn-in prevention method, apparatus, device, and storage medium. Background Art

[0002] Compared with LCD (Liquid Crystal Display) technology, OLED (Organic Light-Emitting Diode) technology has the advantages of a wider color gamut, more vivid pictures, higher contrast, perfect black display (able to achieve pure black), thinner screens, and bendability. Therefore, OLED display devices have gradually occupied the high-end market. OLED screen display relies on organic light emitters to display colors to achieve pixel display. However, the lifespan of each light-emitting organism is inconsistent, and the light-emitting loss is also inconsistent. Therefore, it is easy to produce afterimages (burn-in) of the playing picture, which in turn leads to a shorter lifespan of the OLED screen and a reduced user experience. Therefore, how to provide an effective burn-in prevention solution is one of the technical problems that need to be solved urgently at present. Summary of the Invention

[0081] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description includes the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0082] Figure 1 It is a flowchart of an anti-burn-in screen method shown according to an exemplary embodiment; the method of this embodiment can be applied to a screen display device, such as a television device, a display device, a laptop computer, or a smart phone, etc. Here, the television device will be taken as an example for description.

[0083] As Figure 1 shown, the method includes the following steps S101 - S103:

[0084] In step S101, detect the current application scenario information of the device.

[0085] In this embodiment, after the television device is started, the current application scenario information of the television device can be detected. Among them, the application scenario information of the television device can include at least one of the scenario information of the operating system of the television device popping up a dialog box, the scenario information of the system visualization interface changing, and the scenario information including set user operations.

[0086] The type of the above-mentioned set user operations can be set based on actual needs, such as set to the user clicking to trigger a button on the television remote control, etc. This embodiment does not limit this.

[0087] In step S102, obtain the pre-stored configuration file.

[0088] Among them, the configuration file can include anti-burn-in screen strategies corresponding to various application scenario information, and the anti-burn-in screen strategies corresponding to different application scenario information are different.

[0089] In this embodiment, after detecting the current application scenario information of the device, the configuration file pre-obtained from the cloud server and stored can be obtained.

[0090] For example, after detecting the current application scenario information of the detection device, a pre-stored configuration file can be obtained from the local device. When the configuration file cannot be obtained or the obtained configuration file has expired, a configuration file can be obtained from the cloud server based on a pre-established communication connection with the cloud server and stored locally on the device.

[0091] In one embodiment, taking a TV device as an example, the TV device can be a TV device using the Android system. The anti-burn-in screen strategies corresponding to various application scenario information included in the above configuration file can also include the execution conditions of the anti-burn-in screen strategies corresponding to each different application scenario information, such as the duration of the dialog box popped up by the operating system, the running parameters of the application program, and whether a set user operation for the TV device is detected. It can be understood that in addition to the above content, the content of the above configuration file can also be set according to actual needs, such as being set as the information of the application program, the activity information of the visual interface of the application program, the applicable scenario, the anti-burn-in screen behavior, etc. This embodiment does not limit this. In step S103, the anti-burn-in screen strategy is executed based on the configuration file and the current application scenario information.

[0092] In this embodiment, after obtaining the pre-stored configuration file, it is possible to determine whether the current application scenario information of the TV device satisfies the execution conditions of the anti-burn-in screen strategy based on the application scenario information and the anti-burn-in screen strategies corresponding to various application scenario information recorded in the obtained configuration file and the corresponding execution conditions of the anti-burn-in screen strategy. Furthermore, when the conditions are met, the anti-burn-in screen strategy corresponding to the current application scenario information can be executed.

[0093] For example, the above anti-burn-in screen strategy can be determined to be at least one of closing the dialog box, running a screen saver program, and reducing the screen display brightness based on the actual application scenario information. This embodiment does not limit this.

[0094] From the above description, it can be seen that the method of this embodiment detects the current application scenario information of the device and obtains a pre-stored configuration file. The configuration file contains anti-burn-in screen strategies corresponding to various application scenario information, and the anti-burn-in screen strategies corresponding to different application scenario information are different. Furthermore, the anti-burn-in screen strategy is executed based on the configuration file and the current application scenario information, so that the anti-burn-in screen strategy can be determined based on the application scenario information of the TV device, which can effectively prevent the TV from generating residual images of the playing screen, improve the lifespan of the screen, and enhance the user experience.

[0095] Figure 2It is a flowchart showing how to execute the anti-burn-in strategy based on the configuration file and the application scenario information according to an exemplary embodiment. In this embodiment, on the basis of the above embodiment, taking how to execute the anti-burn-in strategy based on the configuration file and the application scenario information as an example for exemplary illustration. In this embodiment, the current application scenario information includes the scenario information of the system popping up a dialog box, and the anti-burn-in strategy corresponding to the current application scenario information includes: closing the dialog box. On this basis, the execution of the anti-burn-in strategy based on the configuration file and the application scenario information in step S103 above may include the following steps S201-S204:

[0096] In step S201, it is detected that a dialog box pops up on the operating system of the TV device.

[0097] In order to avoid the problem of image residue on the playback screen of the TV device due to the too long duration of the dialog box popped up by the operating system, it is possible to detect the event of the dialog box popped up by the operating system of the TV device after the TV device is started. In this embodiment, when the event of the dialog box popped up by the operating system of the TV device is detected, it can be determined that the application scenario information of the TV device includes the scenario of the dialog box popped up by the operating system.

[0098] Among them, the method of detecting the pop-up of the dialog box can be set according to actual needs, such as by detecting the process of the window management service WMS module performing window addition and deletion, etc., and this embodiment does not limit this.

[0099] In step S202, the first timing starts.

[0100] In this embodiment, after detecting that a dialog box pops up on the operating system of the TV device, a timer can be started for timing (for the sake of distinction, this timing is called "the first timing").

[0101] In step S203, it is judged whether a set user operation is detected within the first time threshold after the start of the first timing: if not, step S204 is executed; if so, step S202 is executed;

[0102] Among them, the first time threshold is determined based on the configuration file, so the first time threshold can be modified by modifying the cloud configuration file, which improves the cloud configurability level of the solution.

[0103] In step S204, the dialog box is closed.

[0104] In this embodiment, when it is detected that no set user operation is detected within the above first duration, it can be determined that the current anti-burn-in strategy execution condition is met, so the anti-burn-in strategy corresponding to the current application scenario information can be executed, that is, closing the dialog box popped up by the system.

[0105] It can be understood that if a set user operation is detected during the above timing process, the timing can be restarted until it is detected that the duration of the pop-up dialog box is greater than or equal to the above first time threshold, and no set user operation is detected during the duration of the pop-up dialog box, it is determined that the current anti-burn-in screen policy execution condition is met, and then the above dialog box can be closed based on the dialog box closing interface provided by the Android TV operating system.

[0106] As can be seen from the above description, in this embodiment, by detecting that the operating system of the TV device pops up a dialog box, and starting the first timing in response to detecting that the system pops up the dialog box; and closing the dialog box in response to no set user operation being detected within the first time threshold after the start of the first timing, it is possible to determine whether the anti-burn-in screen policy execution condition is met for the scenario where the operating system of the TV device pops up a dialog box. Furthermore, by controlling the TV device to execute the anti-burn-in screen policy of closing the operating system dialog box, it is possible to effectively prevent the TV from generating a residual image of the playback screen, improve the lifespan of the screen, and enhance the user experience.

[0107] Figure 3 It is a flowchart showing how to execute the anti-burn-in screen policy based on the configuration file and the application scenario information according to another exemplary embodiment. In this embodiment, on the basis of the above embodiment, an example is given of how to execute the anti-burn-in screen policy based on the configuration file and the application scenario information. In this embodiment, the current application scenario information includes the scenario information of the change of the system visualization interface, and the anti-burn-in screen policy corresponding to the current application scenario information includes: running a screen saver program. On this basis, the execution of the anti-burn-in screen policy based on the configuration file and the application scenario information in the above step S103 may include the following steps S301 - S304:

[0108] In step S301, it is detected that the activity of the application does not apply to hold the screen wake lock or it is determined based on the configuration file that there is no need to detect whether the screen display picture is static.

[0109] In this embodiment, in order to avoid the problem of residual image of the playback screen of the TV device caused by the application scenario information of the change of the system visualization interface, the operation of the application program of the TV device can be detected after the TV device is started. For example, the startup of the application program or the in-application jump can be detected. At this time, the visualization interface Activity of the application program will switch. Therefore, the detection of the application program operation scenario can be achieved by detecting the change or switch of the visualization interface. It can be understood that Activity is a component in the Android system and can be understood as a visualization interface.

[0110] In this embodiment, after detecting the activity switching of the application, it can be detected whether the visual interface Activity of the application has applied for a screen always-on lock, for example, the screen always-on lock can be a keep_screen_on lock to keep the screen awake, and then in any of the following cases, step S302 is executed;

[0111] (1) If the Activity does not apply for the keep_screen_on lock to keep the screen awake;

[0112] (2) The Activity has applied for the keep_screen_on lock, but based on the pre-stored configuration file, it is determined that there is no need to perform the detection of whether the screen display picture is still. It can be understood that the configuration file of this embodiment records which applications need to perform the detection of whether the screen display picture is still.

[0113] On the other hand, the Activity has applied for the keep_screen_on lock, and based on the pre-stored configuration file, it is determined that the screen display image needs to be detected whether it is still. Figure 4 The illustrated embodiment will not be described in detail here.

[0114] In step S302, the second timing starts.

[0115] In this embodiment, when it is detected that the active Activity of the application has not applied to keep the screen wake-up keep_screen_on lock or it is determined based on the configuration file that there is no need to perform a detection of whether the screen display image is still, a timer can be started for timing (for ease of distinction, this timing is called "second timing").

[0116] In step S303, it is determined whether a setting user operation is detected within a second time threshold after the second timing starts: if not, step S304 is executed; if yes, step S302 is executed (i.e., if a setting user operation for the television device is detected, the timing is restarted);

[0117] The second time threshold is determined based on the configuration file, so the second time threshold can be modified by modifying the cloud configuration file, thereby improving the cloud configurability level of the solution.

[0118] In step S304, the screen saver is run.

[0119] In this embodiment, when it is detected that no set user operation is detected within the second time threshold, it can be determined that the current condition for executing the anti-burn-in screen policy is met, and then the anti-burn-in screen policy corresponding to the current application scenario information can be executed, that is, controlling the TV device to run the screen saver program. From the above description, it can be seen that this embodiment provides a method for determining whether the condition for executing the anti-burn-in screen policy is met and determining the corresponding anti-burn-in screen policy in the scenario where "the Activity of the application program running on the TV device does not apply for the keep_screen_on lock for keeping the screen awake" or "the Activity has applied for the keep_screen_on lock but there is no need to detect whether the screen display image is static". Furthermore, the anti-burn-in screen policy of controlling the TV device to run the screen saver program can effectively prevent the TV from generating afterimages of the playing image, improve the lifespan of the screen, and enhance the user experience.

[0120] Figure 4 It is a flowchart showing how to execute the anti-burn-in screen policy based on the configuration file and the application scenario information according to another exemplary embodiment. This embodiment takes how to execute the anti-burn-in screen policy based on the configuration file and the application scenario information as an example for exemplary illustration on the basis of the above embodiment. In this embodiment, the current application scenario information includes the scenario information of the change of the system visualization interface, and the anti-burn-in screen policy corresponding to the current application scenario information includes: running the screen saver program and / or reducing the screen display brightness. On this basis, the execution of the anti-burn-in screen policy based on the configuration file and the application scenario information in step S103 above may include the following steps S401-S404:

[0121] In step S401, it is detected that the activity of the application program has applied for the keep_screen_on lock for keeping the screen awake and it is determined based on the configuration file that it is necessary to detect whether the screen display image is static.

[0122] In this embodiment, when it is detected that the activity of the application program has switched, it can be detected whether the activity of the application program has applied for the keep_screen_on lock for keeping the screen awake. Furthermore, when it is determined that the above Activity has applied for the keep_screen_on lock and it is determined based on the pre-stored configuration file that it is necessary to detect whether the screen display image is static, the following step S402 is continued. It can be understood that the configuration file in this embodiment records which application programs need to detect whether the screen display image is static.

[0123] In step S402, the third timing starts.

[0124] In this embodiment, when it is detected that the Activity of the application has applied for the keep_screen_on lock and it is determined based on the configuration file that it is necessary to detect whether the screen display picture is static, a timer can be started for timing (for the sake of distinction, this timing is referred to as "the third timing").

[0125] In step S403, it is determined whether the screen display picture is detected to be static and no set user operation is detected within the third time threshold after the start of the third timing: if so, step S404 is executed; if not, step S402 is executed (that is, if it is detected that the screen display picture is not static or a set user operation for the TV device is detected, the timing starts again);

[0126] Among them, the third time threshold is determined based on the configuration file. Therefore, the third time threshold can be modified by modifying the cloud configuration file, which improves the cloud configurability level of the solution.

[0127] In step S404, the screensaver program is run and / or the screen display brightness is reduced.

[0128] In this embodiment, when it is detected that the screen display picture of the TV device is static within the third time threshold and no set user operation is detected, it is determined that the current burn-in prevention policy execution condition is satisfied.

[0129] In some embodiments, when it is determined that the current burn-in prevention policy execution condition is satisfied, it is possible to further determine to run the screensaver program and / or reduce the screen display brightness according to the current application scenario information and configuration information, or to run the screensaver program and / or reduce the screen display brightness according to the user's needs.

[0130] For example, when it is determined that the current burn-in prevention policy execution condition is satisfied and the current application scenario is a screen mirroring application, if a screen saver is popped up, the screen mirroring app will enter the background, thus causing the screen mirroring to be disconnected. Therefore, the backlight is reduced. Similar scenarios also include the Bluetooth connection interface, etc. In this type of scenario, popping up the screen saver will damage the current state, so the backlight is also reduced. It can be understood that first, it is judged whether the operation of popping up the screen saver will affect the running state of the current application; if not, the operation of popping up the screen saver or the operations of popping up the screen saver and reducing the backlight can be executed; if it may affect the running state of the current application, the backlight reduction operation is adopted.

[0131] The user can set the execution logic of running the screensaver program and / or reducing the screen display brightness according to their own needs, and the embodiments of the present disclosure do not limit this. For example, Figure 5 is a flowchart showing how to determine that the screen display picture is static according to an exemplary embodiment. AsFigure 5 As shown, the method of this embodiment may further include determining that the screen display is static based on the following steps S501 - S502:

[0132] In step S501, RGB statistical data is collected at preset sampling areas of the screen display at regular intervals.

[0133] Among them, the above-mentioned set time can be set according to actual needs, and this embodiment does not limit this.

[0134] In step S502, in response to detecting that the currently collected RGB statistical data is the same as the previously collected RGB statistical data and there is no sound output from the device, it is determined that the screen display is static.

[0135] The detection method of whether the above-mentioned device has sound output can be set according to actual needs. For example, it can be detected by detecting the audio information of the Audio framework part in the Android operating system framework, etc. This embodiment does not limit this.

[0136] On this basis, when it is determined that the current anti-burn-in screen strategy execution condition is met, the determined anti-burn-in screen strategy can be executed, that is, controlling the TV device to run the screen saver program and / or reducing the screen display brightness.

[0137] From the above description, it can be seen that this embodiment provides a method for determining whether the anti-burn-in screen strategy execution condition is met and determining the corresponding anti-burn-in screen strategy in the scenario where the Activity of the application program running on the TV device has applied for the keep_screen_on lock to keep the screen awake and based on the pre-stored configuration file to determine whether it is necessary to detect whether the screen display is static. Furthermore, the anti-burn-in screen strategy of controlling the TV device to run the screen saver program and / or reducing the screen display brightness can effectively prevent the TV from generating residual images of the playing screen, improve the lifespan of the screen, and enhance the user experience.

[0138] Figure 6 It is a flowchart showing how to determine that the stored first configuration file has expired according to an exemplary embodiment. This embodiment takes how to determine that the stored first configuration file has expired as an example for exemplary illustration on the basis of the above embodiment. As Figure 6 shown, the method of this embodiment may further include determining that the stored first configuration file has expired based on the following steps S601 - S603:

[0139] In step S601, the first version information of the stored first configuration file is obtained.

[0140] In this embodiment, when it is detected that the first configuration file has been stored locally in the TV device, the first version information of the first configuration file can be obtained.

[0141] In one embodiment, the version information of the above configuration file can be set according to actual needs, such as being set as the MD5 check value of the configuration file, etc. This embodiment does not limit this.

[0142] In step S602, the first version information of the first configuration file is compared with the second version information of the second configuration file in the cloud server.

[0143] In this embodiment, after obtaining the first version information of the stored first configuration file, the first version information of the first configuration file can be compared with the second version information of the second configuration file in the cloud server. For example, the first MD5 check value of the first configuration file is compared with the second MD5 check value of the second configuration file, so as to obtain a comparison result, such as being the same or different.

[0144] In step S603, in response to detecting that the first version information is different from the second version information, it is determined that the stored first configuration file has expired.

[0145] In this embodiment, when it is detected that the first version information is different from the second version information, it can be determined that the cloud server has updated the configuration file. Therefore, it can be determined that the first configuration file currently stored in the TV device has expired. Thus, the second configuration file can be obtained from the cloud server and stored locally in the TV device.

[0146] Figure 7A It is a schematic diagram of the application scenario information of the anti-burn-in screen method shown according to an exemplary embodiment; such as Figure 7AAs shown in the figure, in this embodiment, the anti-burn-in strategy can be in the form of an Android system service, that is, the anti-burn-in strategy service runs in the Android TV operating system, and the anti-burn-in strategy service can be started with the TV power-on. Furthermore, when the anti-burn-in strategy service is started or when the above operating system is connected to the network, the anti-burn-in strategy service can detect whether the configuration file has been updated in the cloud (for example, detect whether the configuration file stored locally is different from the configuration file stored on the cloud server). If there is an update, the updated configuration file can be downloaded to the local and stored. On this basis, the current application scenario information of the TV can be detected. For example, when it is detected that the user is operating the TV, the user operation information can be detected based on each module in the Android Framework layer of the Android operating system and passed to the anti-burn-in strategy service, so that the anti-burn-in strategy service can determine whether the anti-burn-in strategy execution condition is met according to the current application scenario information and the cloud configuration file. Furthermore, when it is determined that the condition is met, the anti-burn-in strategy matching the current application scenario information is executed.

[0147] In one embodiment, the running application of the TV device can be detected based on the following method:

[0148] Register an application scenario information query request;

[0149] Detect whether there is a preset scenario change event in the running thread of the device through the query request;

[0150] In response to detecting the preset scenario change event, determine the current application scenario information of the device.

[0151] In some embodiments, the target module in the Android Framework layer of the Android operating system of the TV device is detected to execute a preset process. Among them, the target module executing the preset process includes at least one of the following:

[0152] The Activity Management Service (AMS) module executes the process of activity switching, the Window Management Service (WMS) module executes the process of window addition and deletion, and the Power Management Service (PMS) module executes the process of detecting user key events or application requests for wake locks.

[0153] For example, Figure 7B is a schematic diagram showing the principle of detecting intrusive operating system scenario information according to an exemplary embodiment. As Figure 7BAs shown, after the anti-burn-in screen strategy service is started, it can automatically register its Binder proxy with the Service Manager of the operating system. Then, probes of the Binder proxy of the anti-burn-in screen strategy service can be inserted into the process of activity switching in the Activity Management Service (AMS) module at the framework layer of the Android operating system, the process of window addition and deletion in the Window Management Service (WMS) module, and the process of detecting user key events or an application's request for a wake lock in the Power Management Service (PMS) module. On this basis, when the operating system executes any of the above processes, the probe of the Binder proxy of the anti-burn-in screen strategy service can detect which process is specifically being executed and notify the anti-burn-in screen strategy service, thus realizing the detection of application scenario information.

[0154] Compared with the solutions in the related art that rely on hardware platforms such as screen manufacturers or chip manufacturers, the solution provided in this embodiment is implemented based on the Android operating system framework, and thus has the characteristic of strong portability.
