Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display control method, apparatus, device, and readable storage medium. Background Technology

[0002] With the widespread use of electronic devices such as mobile phones, tablets, and monitors, it is becoming increasingly common for users to spend long periods of time looking at display screens. During continuous viewing, the display screen usually presents text, images, videos, or games in a fixed display mode. The user's main gaze tends to be focused on the same target display area for a long time. Static images with blurred backgrounds do not provide relaxation for the ciliary muscles, which can easily cause visual fatigue and affect viewing comfort.

[0003] Existing eye-protection display technologies typically reduce light stimulation by lowering blue light, adjusting brightness, and reducing flicker. While these methods can improve the screen viewing experience to some extent, they are difficult to differentiate and control based on the areas of interest to the user (the object being viewed).

[0004] Therefore, how to reduce visual fatigue while keeping the main content visible is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] This application provides a display control method, apparatus, device, and readable storage medium that can reduce visual fatigue caused by prolonged viewing at a fixed distance while keeping the main content visible.

[0006] In a first aspect, this application provides a display control method, the method comprising: an electronic device displaying a target interface on a display screen, wherein a target display area in the target interface is displayed on the display screen according to a first display parameter, the target display area including an area of ​​interest to a browsing object on the display screen; and, when a display parameter update condition is met, the electronic device controlling the target display area to be displayed on the display screen according to a second display parameter; wherein the first display parameter and the second display parameter respectively correspond to different visual distance simulation states.

[0007] In this application, the target display area in the target interface includes the area of ​​interest to the browsing object. Therefore, the target display area mainly functions on the display content that the browsing object is actually interested in during the display control process, rather than indiscriminately processing the entire target interface. When the target display area is displayed according to the first display parameters, it can be ensured that the main content of interest to the browsing object can be viewed normally. Furthermore, when the display parameter update condition is met, the electronic device controls the target display area to switch from displaying according to the first display parameters to displaying according to the second display parameters. Since the first display parameters and the second display parameters correspond to different visual distance simulation states, the target display area can switch from one visual distance simulation state to another during the display process, rather than always presenting with a fixed set of display parameters.

[0008] In other words, this application does not merely perform static sharpening on the target display area, but rather, while maintaining the target display area as the primary viewing area, it presents different simulated visual distance states within that area. This way, when viewing the main content, the viewer's visual perception will not remain fixed at a single, fixed distance for an extended period. Therefore, this application can reduce visual fatigue caused by prolonged viewing at the same visual distance while keeping the target display area visible and ensuring normal viewing of the main content, thereby improving the viewing comfort of the display screen.

[0009] In conjunction with the first aspect, in one possible implementation, the first display parameter corresponds to a first simulated visual distance state, the second display parameter corresponds to a second simulated visual distance state, and the target display area switches between the first simulated visual distance state and the second simulated visual distance state. By making the first display parameter correspond to the first simulated visual distance state, the second display parameter correspond to the second simulated visual distance state, and controlling the target display area to switch between the first simulated visual distance state and the second simulated visual distance state, dynamic changes in different visual distances are formed. This avoids displaying a single visual distance and can reduce visual fatigue.

[0010] In conjunction with the first aspect, in one possible implementation, the first display parameter or any of the second display parameters includes at least one of the following: sharpness parameter, edge sharpness parameter, spatial frequency parameter, dot spread function parameter, blur parameter, brightness parameter, and contrast parameter. When the edge sharpness parameter in the first display parameter is greater than the edge sharpness parameter in the second display parameter, and / or the spatial frequency parameter in the first display parameter is greater than the spatial frequency parameter in the second display parameter, and / or the dot spread function parameter in the first display parameter is less than the dot spread function parameter in the second display parameter, the first visual distance simulated by the first visual distance simulation state corresponding to the first display parameter is less than the second visual distance simulated by the second visual distance simulation state corresponding to the second display parameter. By using the display control parameters of the visual distance simulation state, and utilizing the differences between edge sharpness, spatial frequency, and dot spread function parameters to characterize different simulated visual distances, the visual distance simulation state has an executable parameter adjustment basis, thereby achieving the purpose of simulating visual distance by adjusting the display parameters.

[0011] In conjunction with the first aspect, in one possible implementation, the condition for satisfying the display parameter update includes at least one of the following: The target display area displays for a duration equal to the first display duration in the first display parameter. The eye fatigue level of the browsing object has reached a preset level. The eye fatigue level is determined based on the browsing object's eye use status data. The eye use status data includes at least one of fixation point information, pupil change information, and blink frequency information. The eye use status data is determined based on the browsing object's eye image. When the ambient light parameters reach a preset threshold, these parameters include at least one of ambient light brightness and ambient light color temperature. By using at least one of the display duration, eye fatigue level, and ambient light parameters as update conditions for display parameters, the switching of display parameters in the target display area can be triggered based on display duration, the viewing object's eye usage status, and the ambient light status. This allows for setting preset conditions to control the switching of display parameters.

[0012] In conjunction with the first aspect, in one possible implementation, if the simulated first visual distance in the first visual distance simulation state corresponding to the first display parameter is less than the simulated second visual distance in the second visual distance simulation state corresponding to the second display parameter, the electronic device, while controlling the target display area to be displayed on the display screen according to the second display parameter, controls the supplementary lighting module in the display screen to output light within a preset wavelength range to supplement the target interface. When the target display area switches from a display state simulating a closer visual distance to a display state simulating a farther visual distance, the supplementary lighting module is controlled to output light within a preset wavelength range to supplement the display light corresponding to the target interface, thereby improving viewing comfort in different display states.

[0013] In conjunction with the first aspect, in one possible implementation, during the switching of the target display area between the first visual distance simulation state and the second visual distance simulation state, the electronic device controls the target display area to be displayed on the display screen according to the third display parameters; The third display parameter corresponds to a third visual distance simulation state. This third visual distance simulation state simulates a third visual distance that is greater than the first visual distance simulated by the first visual distance simulation state and less than the second visual distance simulated by the second visual distance simulation state. The target display area switches between these three simulation states. Further configuring the third visual distance simulation state allows the target display area to switch between these states, creating a multi-level visual distance simulation variation. This avoids abrupt transitions between the first and second visual distance simulation states, improving the smoothness of the visual distance simulation state transitions.

[0014] Secondly, this application provides a display control device, the device comprising: The display unit is used to display a target interface on a display screen. The target display area in the target interface is displayed on the display screen according to the first display parameters. The target display area includes the area of ​​interest to the browsing object on the display screen. The control unit is used to control the target display area to be displayed on the display screen according to the second display parameters when the display parameter update conditions are met; The first display parameter and the second display parameter respectively correspond to different visual distance simulation states.

[0015] In conjunction with the second aspect, in one possible implementation, the first display parameter corresponds to a first visual distance simulation state, the second display parameter corresponds to a second visual distance simulation state, and the target display area switches between the first visual distance simulation state and the second visual distance simulation state.

[0016] In conjunction with the second aspect, in one possible implementation, the first display parameter or any of the second display parameters includes at least one of a sharpness parameter, an edge sharpness parameter, a spatial frequency parameter, a dot spread function parameter, a blur parameter, a brightness parameter, and a contrast parameter; when the edge sharpness parameter in the first display parameter is greater than the edge sharpness parameter in the second display parameter, and / or the spatial frequency parameter in the first display parameter is greater than the spatial frequency parameter in the second display parameter, and / or the dot spread function parameter in the first display parameter is less than the dot spread function parameter in the second display parameter, the first visual distance simulated by the first visual distance simulation state corresponding to the first display parameter is less than the second visual distance simulated by the second visual distance simulation state corresponding to the second display parameter.

[0017] In conjunction with the second aspect, in one possible implementation, the condition for satisfying the display parameter update includes at least one of the following: The target display area displays for a duration equal to the first display duration in the first display parameter. The eye fatigue level of the browsing object has reached a preset level. The eye fatigue level is determined based on the browsing object's eye use status data. The eye use status data includes at least one of fixation point information, pupil change information, and blink frequency information. The eye use status data is determined based on the browsing object's eye image. The ambient light parameters reach a preset parameter threshold, which includes at least one of ambient light brightness and ambient light color temperature.

[0018] In conjunction with the second aspect, in one possible implementation, if the first visual distance simulated by the first visual distance simulation state corresponding to the first display parameter is less than the second visual distance simulated by the second visual distance simulation state corresponding to the second display parameter, then when controlling the target display area to be displayed on the display screen according to the second display parameter, the control unit is also used to control the supplementary light module in the display screen to output light within a preset wavelength range to supplement the target interface.

[0019] In conjunction with the second aspect, in one possible implementation, during the process of the target display area switching between the first visual distance simulation state and the second visual distance simulation state, the control unit is further configured to control the target display area to be displayed on the display screen according to the third display parameters; The third display parameter corresponds to a third visual distance simulation state. The third visual distance simulated by the third visual distance simulation state is greater than the first visual distance simulated by the first visual distance simulation state and less than the second visual distance simulated by the second visual distance simulation state. The target display area switches between the first visual distance simulation state, the third visual distance simulation state and the second visual distance simulation state.

[0020] Thirdly, this application provides an electronic device including a display screen, a processor, and a memory for storing computer programs or instructions; the processor is used to execute the computer programs or instructions, causing the electronic device to perform the methods described in the first aspect or any possible implementation of the first aspect.

[0021] Fourthly, this application provides a computer-readable storage medium storing a computer program or instructions that, when run on a computer, cause the computer to perform the method described in the first aspect or any possible implementation thereof.

[0022] Fifthly, this application provides a computer program product containing program instructions that, when run, causes the method described in the first aspect or any possible implementation of the first aspect to be executed.

Detailed Implementation

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The specific operation methods and functional descriptions in the method embodiments can also be applied to the device embodiments or system embodiments.

[0026] In the various embodiments of this application, unless otherwise specified or in case of logical conflict, the terminology and / or descriptions of different embodiments are consistent and can be referenced by each other. The technical features of different embodiments can be combined to form new embodiments according to their inherent logical relationship.

[0027] In this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. In the textual description of this application, the character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, and c can mean: a, or, b, or, c, or, a and b, or, a and c, or, b and c, or, a, b, and c. Here, a, b, and c can each be single or multiple.

[0028] In this application, terms such as "first" and "second" are merely for descriptive convenience and are not intended to limit the scope of the embodiments of this application. For example, they distinguish different instruction information, rather than describing a specific order or sequence. Such descriptions can be interchanged where appropriate to describe solutions other than those in the embodiments of this application.

[0029] In this application, the words "exemplary," "for example," "such as," etc., are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as an "example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the term "example" is used to present concepts in a concrete manner.

[0030] In this application, expressions such as "B corresponding to A" can indicate that there is a correspondence / mapping relationship between A and B, and that B can be determined based on A. Determining B based on A includes determining B based solely on A, as well as determining B based on A and other information.

[0031] The following describes the terminology used in this application.

[0032] Target interface: This can refer to the interface currently displayed on the screen, such as a document interface, web page interface, video screen, game interface, or image interface, etc.

[0033] Target display area: This can refer to the area in the target interface that the browsing object mainly focuses on or is of interest to, such as a text area, a character area, an object area, a game character area, or an interactive control area, etc.

[0034] Viewing audience: This can refer to users who are viewing the display screen.

[0035] Visual distance simulation state: This refers to a display state that simulates different visual perceptions of near and far distances by adjusting display parameters, and does not necessarily represent a real change in the physical focal plane of the screen. The visual distance simulation state in this application can be calibrated using a virtual display distance or a virtual focus distance. This virtual display distance or virtual focus distance is used to characterize the near and far visual simulation effects corresponding to different sets of display parameters, and does not represent a real change in the physical focal plane of the display screen.

[0036] Display parameters: These can refer to parameters used to control the display effect of the target display area, and may include at least one or more of the following: sharpness parameters, edge sharpness parameters, spatial frequency parameters, dot spread function parameters, blur parameters, brightness parameters, and contrast parameters. In this application, they may be referred to as first display parameters, second display parameters, or third display parameters to distinguish different groups of display parameters.

[0037] The electronic devices involved in this application are described below.

[0038] See Figure 1 , Figure 1 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. Figure 1As shown, the electronic device may include a display screen, a processor, a memory, and a display driver module. The display screen is used to display a target interface, which may include a target display area, which can be an area of ​​interest to the browsing object on the display screen. The memory is used to store programs or instructions, and the processor is used to execute the programs or instructions stored in the memory to implement the display control method provided in this application embodiment.

[0039] In this application, the electronic device can be a device with display and data processing functions. Exemplarily, the electronic device may include mobile phones, tablets, laptops, desktop computers, monitors, televisions, learning machines, educational screens, office monitors, e-readers, in-vehicle display devices, smart glasses, gaming devices, smart interactive screens, conference tablets, medical display devices, industrial control display devices, etc., but this application does not limit the scope of the embodiments.

[0040] The processor can be connected to a display screen, a memory, and a display driver module. The processor can determine the display parameters corresponding to the target display area and, when the display parameter update conditions are met, control the display driver module to switch the target display area from displaying according to a first display parameter to displaying according to a second display parameter. The first and second display parameters correspond to different visual distance simulation states. The display driver module can adjust at least one of the following parameters of the target display area—clarity, edge sharpness, spatial frequency, dot spread function, blur, brightness, and contrast—according to control commands output by the processor, thereby causing the target display area to present different visual distance simulation states.

[0041] In one possible implementation, the electronic device may further include a content recognition module. This module can be used to recognize the displayed content on a target interface to determine the region of interest (ROI) and designate it as the target display area. For example, the target display area may include at least one of a text area, a character area, an object area, a game character area, and an interactive control area. The content recognition module can be implemented based on artificial intelligence algorithms; for instance, when the content recognition module is an AI semantic recognition module, it can learn the content that needs to be prioritized for recognition. The content recognition module can also update the model parameters, recognition rules, region priority rules, and / or the correspondence between content type and target display area based on at least one of historical display parameters, user operation data, user gaze area, historical determination results of the target display area, and user manual adjustment results. Thus, the content recognition module can adaptively adjust the method for determining the target display area according to the actual usage of the electronic device, rather than being limited to fixed recognition rules or fixed content types. Optionally, the electronic device may also record historical display parameters of the browsed object. Historical display parameters may include at least one of the following: historical switching cycle of the browsed object, first display duration, second display duration, third display duration, perspective ratio, brightness parameter, contrast parameter, blur parameter, and edge sharpness parameter. Electronic devices can adjust at least one of the following display parameter update conditions, first display parameter, second display parameter, and third display parameter based on historical display parameters.

[0042] In one possible implementation, the target interface may further include a non-target display area. The non-target display area can be displayed with different display parameters than the target display area; for example, the non-target display area can be weakened or blurred to reduce visual interference with the target display area. Optionally, the content recognition module can identify whether the non-target display area belongs to a secondary area or a redundant background area, thereby achieving accurate classification and labeling of the screen content and providing data support for simulating display states at different visual distances.

[0043] In one possible implementation, the electronic device may further include at least one of an eye image acquisition module (or eye tracking module), an ambient light detection module, and a supplementary lighting module. The eye image acquisition module can be used to acquire eye images of the viewed object, so that the processor can determine the object's eye usage status data based on the eye images and further determine the eye fatigue level. The ambient light detection module can be used to acquire ambient light brightness and / or ambient light color temperature, so that the processor can determine whether the display parameter update conditions are met based on the ambient light parameters, or adjust at least one of the first display parameters and the second display parameters. The supplementary lighting module can be used to output light within a preset wavelength range to supplement the target interface when the target display area is displayed according to display parameters corresponding to a larger visual distance.

[0044] It should be noted that, Figure 1 Some modules can be selectively configured according to the specific configuration of the electronic device. For example, the content recognition module, eye image acquisition module, ambient light detection module, and supplementary lighting module can be optionally included in the electronic device. This application does not limit the specific hardware form and integration method of each module.

[0045] The display control method of this application embodiment will be described by way of example below.

[0046] See Figure 2 , Figure 2 This is a flowchart illustrating a display control method provided in an embodiment of this application. Figure 2 As shown, the display control method may include, but is not limited to, the following steps: S201, the electronic device displays a target interface on a display screen. The target display area in the target interface is displayed on the display screen according to the first display parameters. The target display area includes the area of ​​interest of the browsing object on the display screen.

[0047] The target interface can be a document reading interface, a web browsing interface, a video playback interface, an image display interface, a game interface, or an office interface, etc. The target interface includes a target display area, which is the area on the screen that the viewed object is interested in.

[0048] In one possible implementation, the target display area can be determined based on the content recognition results of the target interface. Specifically, the electronic device can perform content recognition on the displayed content of the target interface, obtain the content recognition results, and determine the region of interest in the target interface based on the content recognition results, using this region of interest as the target display area. The content recognition results can include at least one of the following: content type of the displayed content, region location, region area, region boundary, and region priority. The content type of the displayed content can include at least one of the following: text type, character type, object type, game character type, and interactive control type. The user interaction state can include at least one of the following: click state, swipe state, selection state, and pause state.

[0049] In another possible implementation, the target display area can be determined based on at least one of the following: user operation data of the browsed object, gaze point information, and preset area rules. User operation data can include at least one of click, swipe, pause, and selection operations; gaze point information can be used to characterize the gaze position of the browsed object within the target interface; and preset area rules can be used to indicate how the target display area is determined in different display scenarios.

[0050] Optionally, when the electronic device determines multiple candidate regions of interest based on the content recognition results, the electronic device can determine the target display area from the multiple candidate regions of interest based on at least one of the region type, region area, region location, user gaze point, and user interaction state of each candidate region of interest.

[0051] For example, when the target interface includes both text and image areas, if the electronic device detects that the viewer's gaze is on the text area, or detects that the viewer is hovering over the text area, then the text area can be designated as the target display area. In another example, when the target interface is a game interface, the electronic device can designate at least one of the game character area, operation button area, or skill control area as the target display area.

[0052] Optionally, the target interface may also include non-target display areas. These non-target display areas may include secondary display areas and background display areas. Secondary display areas may be display areas related to the target display area but not of primary interest, while background display areas may be areas within the target interface other than the target and secondary display areas. The electronic device can control the non-target display areas to display with display parameters different from those of the target display area. For example, the sharpness parameter corresponding to the secondary display area may be lower than that corresponding to the target display area, and the sharpness parameter corresponding to the background display area may be lower than that corresponding to the secondary display area. The secondary display area and the background display area maintain their corresponding display parameters unchanged during the visual distance simulation state switching process within the target display area.

[0053] For example, the sharpness parameter of the secondary display area can be 50% to 60% of the sharpness parameter of the target display area, and the sharpness parameter of the background display area can be 20% to 30% of the sharpness parameter of the target display area. Alternatively, the electronic device can also weaken the display of the secondary display area and / or the background display area by increasing the blur parameter, decreasing the edge sharpness parameter, and decreasing the spatial frequency parameter. The above proportions are merely examples, and the embodiments of this application are not limited thereto.

[0054] Optionally, the electronic device can also adjust at least one of the following: display parameter update conditions, first display parameter, second display parameter, and third display parameter, according to the display scenario of the target interface. The display scenario can include at least one of the following: text display scenario, video / image display scenario, game display scenario, and still image display scenario. For example, in a text display scenario, the electronic device can increase the proportion of display time for simulated visual distance states with larger visual distances; in a video / image display scenario or a game display scenario, the electronic device can decrease the proportion of display time for simulated visual distance states with larger visual distances; in a still image display scenario, the electronic device can extend the switching cycle between different simulated visual distance states of the target display area.

[0055] In a specific application scenario, see Figure 3 , Figure 3 This is a schematic diagram illustrating a target display area determination process provided in an embodiment of this application. Figure 3 As shown, in one possible implementation, the electronic device can determine the target display area in the target interface through an Artificial Intelligence (AI) semantic recognition module. Specifically, the electronic device can first capture screen frames to obtain the screen frames corresponding to the target interface. Then, it can perform image preprocessing on the captured screen frames to obtain a processed image that is easier for content recognition.

[0056] After image preprocessing, the electronic device can perform content classification and recognition on the processed image. Content classification and recognition can include at least one of text scene recognition, film / image scene recognition, and game scene recognition. For example, when the target interface is identified as a text scene, the electronic device can identify the document text area, webpage text area, or other text display area as candidate key areas; when the target interface is identified as a film / image scene, the electronic device can identify the main character area, animal area, core object area, or center area of ​​the screen as candidate key areas. When the target interface is identified as a game scene, the electronic device can identify the game character area, operation button area, skill control area, or interactive control area as candidate key areas. It should be noted that the key area here refers to the target display area in this application.

[0057] Furthermore, the electronic device can extract key areas from candidate key areas to obtain key areas in the target interface. This key area can serve as the target display area, i.e., the area of ​​interest to the browsing object, and can be called the Region of Interest (ROI). After extracting the key area, the electronic device can also mark secondary areas and blur background areas. Secondary areas can be areas related to the target display area but not primarily of interest to the browsing object. The background area can be any area in the target interface other than the target display area and secondary areas. Based on the results of key area extraction, secondary area marking, and background area blurring, the electronic device can output focus control commands.

[0058] The output focus control command can be understood as an output command for display control. For example, it could be a command instructing the dynamic focus drive module to control the target display area to display according to a first display parameter, a second display parameter, or a third display parameter; or it could be a command instructing the dynamic focus drive module to adjust at least one of the following parameters: sharpness parameter, edge sharpness parameter, spatial frequency parameter, dot spread function parameter, blur parameter, brightness parameter, and contrast parameter. Through this method, the electronic device can determine the area of ​​interest for the browsing object based on the displayed content of the target interface and further perform differentiated display control on that area.

[0059] In one possible implementation, the content recognition module can load a content recognition model and enter the content recognition state of the target interface after the electronic device is started. The content recognition model can be at least one of a lightweight convolutional neural network model, an object detection model, a semantic segmentation model, a saliency detection model, or other artificial intelligence models. The electronic device can perform content recognition on the target interface according to a preset detection cycle, or update the target display area when it detects changes in the displayed content of the target interface, a change in the display scene, a user interaction with the viewed object, or a change in the gaze point of the viewed object.

[0060] For example, the electronic device can identify the displayed content in the target interface according to the refresh cycle of the display screen or according to a detection cycle shorter than the refresh cycle of the display screen. For example, the electronic device can perform frame acquisition and content recognition at a preset frequency of 60Hz, 120Hz or other preset frequencies. The above recognition frequencies are merely examples and are not limited in this application embodiment.

[0061] In one possible implementation, when the electronic device determines that the target display area is in a simulated visual distance state with a relatively large visual distance, the electronic device can still maintain the text outlines, key edges, button boundaries, or other main content in the target display area to a preset readability. That is, in the second simulated visual distance state, the electronic device can reduce the spatial frequency parameters, edge sharpness parameters, or increase the dot spread function parameters of the target display area, but will not make the main content in the target display area completely indistinguishable. The preset readability can be determined based on the displayed content of the target interface, the display screen size, the browsing object settings, or the display scene.

[0062] When displaying the target interface, the electronic device controls the target display area to be displayed on the display screen according to the first display parameters. The first display parameters correspond to a first visual distance simulation state. The first visual distance simulation state can be a near visual distance simulation state. In the near visual distance simulation state, the target display area can have a higher resolution parameter, a higher edge sharpness parameter, a higher spatial frequency parameter, and a smaller dot spread function parameter.

[0063] S202, when the display parameter update condition is met, the electronic device controls the target display area to be displayed on the display screen according to the second display parameter; wherein, the first display parameter and the second display parameter correspond to different visual distance simulation states.

[0064] When the display parameter update conditions are met, the electronic device controls the target display area to be displayed on the display screen according to the second display parameters. The second display parameters correspond to a second visual distance simulation state, which is different from the first visual distance simulation state.

[0065] In one possible implementation, the display parameter update condition can be used to trigger the target display area to switch from displaying according to a first display parameter to displaying according to a second display parameter. The display parameter update condition may include at least one of a display duration condition, an eye fatigue level condition, and an ambient light condition. Meeting the display parameter update condition includes at least one of the following: the display duration of the target display area according to the first display parameter reaches the first display duration in the first display parameter; the eye fatigue level of the viewed object reaches a preset level, which is determined based on the user's eye usage data, including at least one of fixation point information, pupil change information, and blink frequency information, and is determined based on the user's eye image; the ambient light parameter reaches a preset parameter threshold, which includes at least one of ambient light brightness and ambient light color temperature.

[0066] In one possible implementation, the display parameter update condition may include: the target display area displays according to the first display parameter for a duration equal to a first display duration in the first display parameter. The first display parameter may include the first display duration, or the first display parameter may be stored in association with the first display duration. The first display duration may be used to indicate the continuous display time of the target display area in a first visual distance simulation state. When the target display area displays according to the first display parameter for a duration equal to the first display duration, the electronic device may determine that the display parameter update condition is met and control the target display area to display according to the second display parameter.

[0067] For example, when the first display parameter corresponds to the near visual distance simulation state, the first display duration can be 2 seconds; when the third display parameter corresponds to the medium visual distance simulation state, the third display duration can be 1 second; and when the second display parameter corresponds to the far visual distance simulation state, the second display duration can be 2 seconds. The electronic device can control the target display area to display the near visual distance simulation state, the medium visual distance simulation state, and the far visual distance simulation state sequentially, forming a switching cycle of approximately 5 seconds. The above display duration and switching cycle are only examples and can be adjusted through firmware parameters, user settings parameters, display scene parameters, or eye fatigue level.

[0068] In another possible implementation, the display parameter update condition may include: the eye fatigue level of the viewed object reaching a preset level. The electronic device can acquire eye images of the viewed object and determine the object's eye usage status data based on the eye images. The electronic device can determine the eye fatigue level of the viewed object based on the eye usage status data, and determine that the display parameter update condition is met when the eye fatigue level reaches the preset level.

[0069] For example, eye fatigue levels can include a first fatigue level, a second fatigue level, and a third fatigue level. The first fatigue level can correspond to mild fatigue, the second fatigue level can correspond to moderate fatigue, and the third fatigue level can correspond to severe fatigue. For instance, when the blinking frequency is greater than or equal to 15 times / minute and the pupil dilates normally, it can be determined as the first fatigue level; when the blinking frequency is between 10 and 14 times / minute and the pupil constricts slightly, it can be determined as the second fatigue level; when the blinking frequency is less than 10 times / minute, the pupil constricts significantly, and / or the fixation point is unstable, it can be determined as the third fatigue level. When the eye fatigue level reaches the second or third fatigue level, the electronic device can determine that the display parameter update conditions are met and control the target display area to display according to the second display parameters, or increase the proportion of display time in the second visual distance simulation state.

[0070] In another possible implementation, the display parameter update condition may include: the ambient light parameter reaching a preset parameter threshold. The ambient light parameter may include at least one of ambient light brightness and ambient light color temperature. The electronic device can obtain the ambient light brightness and / or ambient light color temperature through an ambient light detection module, and determine that the display parameter update condition is met when the ambient light brightness and / or ambient light color temperature reaches the corresponding preset parameter threshold.

[0071] For example, when the ambient light intensity is greater than or equal to a first brightness threshold, the electronic device can adjust the brightness parameters, contrast parameters, and / or the display duration percentage of the second visual distance simulation state of the target display area. When the ambient light intensity is less than a second brightness threshold, the electronic device can reduce the brightness parameters of the target interface, adjust the color temperature parameters of the target interface, and / or increase the supplementary light frequency of the supplementary light module. The first brightness threshold and the second brightness threshold can be 500 lux, or the first brightness threshold and the second brightness threshold can be set separately according to different display devices or different usage scenarios. The above thresholds are merely examples, and the embodiments of this application do not limit them.

[0072] See Figure 4 , Figure 4 This is a flowchart illustrating a human eye-tracking display control method as provided in an embodiment of this application. Figure 4 As shown, in one possible implementation, the electronic device can perform closed-loop adjustment of the display control process of the target display area based on the state of human eyes and the state of ambient light.

[0073] Specifically, the electronic device can collect information on the human eye state to obtain at least one of the following eye state information: fixation point, pupil size, and blink frequency. That is, the electronic device can acquire eye images of the viewed object through an eye image acquisition module or an eye tracking module, and determine at least one of the following based on the eye images: fixation point information, pupil change information, and blink frequency information. The electronic device can then classify eye fatigue based on the aforementioned eye state information, obtaining a level of mild, moderate, or severe eye fatigue. For example, the eye fatigue level can include mild, moderate, and severe fatigue levels; the electronic device can determine the current eye fatigue level of the viewed object based on at least one of blink frequency, pupil change degree, and fixation point stability.

[0074] Furthermore, the electronic device can also perform ambient light detection to obtain ambient light parameters. Ambient light parameters may include at least one of ambient light brightness and ambient light color temperature. The electronic device can determine the current display environment based on the ambient light parameters and use them as a reference condition for adjusting the display parameters of the target display area.

[0075] After obtaining the eye fatigue level assessment results and / or ambient light detection results, the electronic device can adaptively adjust the focus parameters. This adaptive adjustment of focus parameters can be understood as adjusting the display parameters of the target display area, the display parameter update conditions, or the switching parameters between different simulated visual distance states, and is not limited to changing the physical focal length through optical or mechanical structures. For example, adaptive adjustment of focus parameters may include at least one of zoom cycle adjustment, distant scene proportion adjustment, and bokeh intensity adjustment.

[0076] The zoom cycle adjustment can be used to adjust the switching cycle of the target display area between the first visual distance simulation state and the second visual distance simulation state, or to adjust the switching cycle of the target display area between the first visual distance simulation state, the third visual distance simulation state, and the second visual distance simulation state. The distant view proportion adjustment can be used to adjust the duration proportion of the visual distance simulation state with a larger visual distance within a switching cycle. The blur intensity adjustment can be used to adjust at least one of the following parameters corresponding to the target display area or non-target display area: blur parameter, sharpness parameter, edge sharpness parameter, spatial frequency parameter, and point spread function parameter.

[0077] After adjusting the zoom cycle, the proportion of distant views, and / or the blur intensity, the electronic device can perform dynamic zone focusing. Dynamic zone focusing can be understood as the electronic device controlling the target display area to display according to a first, second, or third display parameter based on the adjusted display parameters or display parameter update conditions. This allows the target display area to switch between different simulated visual distance states, essentially dynamically allocating virtual focus distances to the target display area. Simultaneously, the electronic device can also weaken or blur non-target display areas as needed, i.e., perform progressive blurring of non-target display areas. This achieves the goal of simulating the natural visual habit of the human eye—"sharp focus, blurred peripheral vision."

[0078] After performing dynamic zone focusing, the electronic device can provide real-time status feedback. This real-time feedback may include at least one of the following: re-acquiring the user's eye status, re-detecting ambient light parameters, recording current display parameters, recording the current eye fatigue level, or recording the current visual distance simulation state. Based on this real-time feedback, the electronic device can continue to acquire user eye status and classify eye fatigue levels, and then adaptively adjust the focusing parameters again based on the new eye fatigue level classification results and / or ambient light detection results, thus forming a closed-loop control process.

[0079] For example, when the eye fatigue grading result indicates that the viewed object is under moderate or severe fatigue, the electronic device can increase the proportion of distant scenery, that is, increase the duration of the simulated visual distance state with a larger visual distance. When the ambient light detection result indicates that the ambient light brightness is low, the electronic device can adjust the brightness parameters, contrast parameters, or blur intensity of the target display area. When the gaze point changes, the electronic device can readjust the target display area or adjust the display parameters of the corresponding area according to the area corresponding to the gaze point. Through the above methods, the electronic device can achieve closed-loop adjustment of the display state of the target display area based on human eye state acquisition, eye fatigue grading, ambient light detection, adaptive adjustment of focus parameters, zoom cycle adjustment, distant scenery proportion adjustment, blur intensity adjustment, execution of dynamic zone focusing, and real-time status feedback. It should be noted that the focusing or zooming in this application can be understood as forming different simulated visual distance states through changes in display parameters, and is not limited to changing the actual optical focal length.

[0080] Optionally, the electronic device can adjust at least one of the following parameters of the target interface: brightness parameter, color temperature parameter, short-wavelength blue light suppression parameter, supplementary light frequency, and the proportion of display time in the simulated visual distance state with a larger visual distance, based on the ambient light brightness and ambient light color temperature. For example, when the ambient light brightness is greater than or equal to 500 lux, the electronic device can increase the proportion of display time in the simulated second visual distance state; when the ambient light brightness is less than 500 lux, the electronic device can decrease the brightness parameter of the target interface, adjust the color temperature parameter, increase the supplementary light frequency of the supplementary light module, and / or increase the short-wavelength blue light suppression level. The 500 lux mentioned above is merely an example, and this application embodiment does not limit this.

[0081] In one possible implementation, before acquiring the human eye state data, the electronic device can initialize or calibrate the eye tracking module and the eye fatigue detection module. Exemplarily, the eye tracking module can acquire images of the viewed object's eyes using a front-facing camera, infrared sensor, or depth sensor, and determine at least one of fixation point information, pupil change information, and blink frequency information based on the eye images. The sampling frequency of the eye tracking module can be 30Hz or other frequencies, and the fixation point recognition accuracy can be set according to the hardware configuration of the electronic device. The above sampling frequency and recognition accuracy are merely examples, and this application embodiment does not limit them.

[0082] In one possible implementation, the electronic device can determine the gaze area of ​​the viewed object based on gaze point information. When the gaze area matches the target display area, the electronic device can maintain the switching mode of the target display area between different visual distance simulation states. Optionally, the electronic device can determine the current gaze area of ​​the viewed object based on the gaze point information. If the current gaze area is inconsistent with the determined target display area, the electronic device can update the current gaze area to the new target display area, or improve the sharpness parameters, edge sharpness parameters, and / or contrast parameters of the current gaze area. For example, the electronic device can reduce the blur parameter of the current gaze area, or reduce the blur degree of the current gaze area, so that the area currently gazed at by the viewed object can be viewed normally.

[0083] In one possible implementation, the electronic device can adjust the display control method of the target display area according to the eye fatigue level. For example, when the eye fatigue level is at the first fatigue level, the electronic device can maintain the current display parameter update conditions; when the eye fatigue level is at the second fatigue level (also known as moderate fatigue), the electronic device can increase the proportion of display time for simulated visual distances with larger visual distances, for example, adjusting this proportion to 50%, and reducing the contrast parameter of the target interface, for example, by 10%; when the eye fatigue level is at the third fatigue level (also known as severe fatigue), the electronic device can control the target display area to display according to the display parameters corresponding to simulated visual distances with larger visual distances for a preset duration. For example, the electronic device can control the target display area to display according to the display parameters simulating a visual distance of 8m to 10m and maintain this for 30 seconds, and the electronic device can trigger a forced distant viewing mode and output a prompt message. The prompt message can be a text prompt, voice prompt, icon prompt, or other gentle reminder method, used to prompt the viewer to rest or adjust the viewing distance. The above values ​​are merely examples, and the embodiments of this application do not limit this.

[0084] In one possible implementation, the electronic device can also adjust the display control method of the target display area based on the viewing distance between the viewed object and the display screen. When the viewing distance is less than a preset distance threshold, the electronic device can increase the proportion of display time for simulated visual distance states with larger visual distances, or increase the blur parameters of non-target display areas. For example, when the viewing distance is less than 30cm, the electronic device can increase the proportion of display time for simulated visual distance states with larger visual distances to 60%, and deepen the blurring of the background display area. The 30cm and 60% mentioned above are just examples and can be adjusted according to the display device type, the age of the viewed object, or user settings.

[0085] See Figure 5 , Figure 5 This is a schematic diagram of a hardware layer structure provided for an embodiment of this application. For example... Figure 5 As shown, in one possible implementation, the electronic device may include at least one of the following: a housing / structural component, a front-facing AI camera, an infrared sensor, a top screen layer, an anti-glare nano-optical coating, a pixel emitting layer, a backlight layer / driving layer, a 650nm red light fill light strip, and a main control circuit board.

[0086] The housing / structural components can be used to support and secure the front-facing AI camera, infrared sensor, display screen, and main control circuit board. The front-facing AI camera can capture images of the user's eyes, allowing the electronic device to determine the user's eye-use status data based on these images. This eye-use status data can include at least one of fixation point information, pupil change information, and blink frequency information. The infrared sensor can be used to assist in capturing the user's eye-use status or to detect the viewing distance between the user and the display screen.

[0087] The display screen may include a top screen layer, an anti-glare nano-optical coating, a pixel emissive layer, and a backlight / driving layer. The top screen layer can serve as an outer protective layer for the display screen. The anti-glare nano-optical coating can be disposed on one side of the top screen layer to reduce ambient light reflection interference on the display screen surface. The pixel emissive layer may include an OLED pixel emissive layer or an LCD pixel display layer. Figure 5 The "pixel-emitting layer OLED / LCD pixel-level focusing" shown can be understood as follows: electronic devices can control display parameters of a target display area based on pixels or pixel regions. For example, they can control at least one of the following parameters: sharpness, edge sharpness, spatial frequency, dot spread function, blur, brightness, and contrast, to make the target display area present different simulated visual distance states. This pixel-level focusing is not limited to changing the actual physical focal length through mechanical or optical structures.

[0088] The backlight / driving layer can be used to provide backlight or display driving signals to the display screen. The main control circuit board can be connected to the front-facing AI camera, infrared sensor, backlight / driving layer, and 650nm red light fill light strip. The main control circuit board may include at least one of a processor, memory, and driving circuitry. The processor can execute computer programs or instructions to control the target display area to display according to a first display parameter or a second display parameter.

[0089] A 650nm red light supplementary light strip can be used as a specific implementation of a supplementary lighting module. If the simulated first visual distance corresponding to the first display parameter is less than the simulated second visual distance corresponding to the second display parameter, then when the electronic device controls the target display area to be displayed on the display screen according to the second display parameter, the main control circuit board can control the 650nm red light supplementary light strip to output light within a preset wavelength range to supplement the target interface.

[0090] For example, the preset wavelength range may include 620nm to 700nm, or it may include a wavelength range around 650nm. The 650nm red light supplement light strip may be disposed in the backlight layer, driving layer, inside the display module, or in the peripheral structure of the display screen. The above-mentioned 650nm is only an example of a preset wavelength range. The embodiments of this application do not limit the supplement light module to output light of a fixed wavelength, nor do they limit the supplement light module to be in the form of a light strip.

[0091] In one possible implementation, the main control circuit board can also control at least one of the following: the eye image captured by the front-facing AI camera, the eye distance detected by the infrared sensor, the current visual distance simulation state of the target display area, ambient light parameters, and the display content of the target interface. This allows the circuit board to control at least one of the following: the duration, intensity, and frequency of the 650nm red light supplementary illumination strip. Thus, the electronic device can achieve display control by combining the hardware supplementary illumination structure during the switching of the visual distance simulation state in the target display area.

[0092] In one possible implementation, the first display parameter can correspond to a first visual distance simulation state, and the second display parameter can correspond to a second visual distance simulation state. The first visual distance simulation state and the second visual distance simulation state can be different visual distance simulation states. The electronic device can control the target display area to switch between the first visual distance simulation state and the second visual distance simulation state.

[0093] For example, when the target display area is displayed according to the first display parameters, the target display area can present a first visual distance simulation state; when the display parameter update condition is met, the electronic device can control the target display area to be displayed according to the second display parameters, so that the target display area switches from the first visual distance simulation state to the second visual distance simulation state. Thus, the target display area is not always displayed with the same display parameters, but can change between different visual distance simulation states.

[0094] Optionally, the switching between the first visual distance simulation state and the second visual distance simulation state of the target display area can be a single switch. For example, when the display duration of the target display area according to the first display parameters reaches the first display duration, the electronic device can control the target display area to switch to display according to the second display parameters.

[0095] Optionally, the switching between the first visual distance simulation state and the second visual distance simulation state can be periodic or cyclical. For example, the electronic device can control the target display area to display a first display duration according to the first display parameters, and then switch to displaying a second display duration according to the second display parameters when the display parameter update condition is met; after displaying the second display duration according to the second display parameters, it switches back to displaying according to the first display parameters when the display parameter update condition is met. This process is repeated, causing the target display area to cyclically change between the first visual distance simulation state and the second visual distance simulation state.

[0096] The first visual distance simulation state can be a near visual distance simulation state, and the second visual distance simulation state can be a far visual distance simulation state; or, the first visual distance simulation state and the second visual distance simulation state can also be other visual distance simulation states with different near and far relationships, which are not limited in this embodiment.

[0097] In another possible implementation, during the switching between the first visual distance simulation state and the second visual distance simulation state, the target display area is controlled to be displayed on the display screen according to the third display parameters; The third display parameter corresponds to a third visual distance simulation state. The third visual distance simulated by the third visual distance simulation state is greater than the first visual distance simulated by the first visual distance simulation state and less than the second visual distance simulated by the second visual distance simulation state. The target display area switches between the first visual distance simulation state, the third visual distance simulation state and the second visual distance simulation state.

[0098] For example, before the target display area switches from the first visual distance simulation state to the second visual distance simulation state, the target display area is controlled to be displayed on the display screen according to the third display parameter; wherein, the third display parameter corresponds to the third visual distance simulation state, the third visual distance simulated by the third visual distance simulation state is greater than the first visual distance simulated by the first visual distance simulation state, and less than the second visual distance simulated by the second visual distance simulation state.

[0099] The electronic device can also set a third visual distance simulation state between the first and second visual distance simulation states. The third visual distance simulation state can be a mid-range visual distance simulation state. For example, the first, third, and second visual distance simulation states can correspond to virtual display distances of approximately 30cm, 50cm, and 5m to 10m, respectively. The electronic device can control the target display area to switch between the first, third, and second visual distance simulation states in that order. The above virtual display distances are merely examples; in actual applications, they can be adjusted according to the display screen size, the content displayed on the target interface, the user habits of the browsing object, or the preset configuration of the electronic device.

[0100] See Figure 6 , Figure 6 This is a schematic diagram illustrating a visual distance simulation state switching process provided in an embodiment of this application. Figure 6 As shown, the target display area can switch between multiple visual distance simulation states, which may include a first visual distance simulation state, a third visual distance simulation state, and a second visual distance simulation state.

[0101] The simulation states are as follows: the first visual distance simulation state corresponds to the first display parameter, with a display duration of T1, and is used to simulate the first visual distance; the third visual distance simulation state corresponds to the third display parameter, with a display duration of T3, and is used to simulate the third visual distance; the second visual distance simulation state corresponds to the second display parameter, with a display duration of T2, and is used to simulate the second visual distance. The first, third, and second visual distances satisfy the condition: "First visual distance < Third visual distance < Second visual distance". That is, the first visual distance simulation state can be used to simulate relatively close visual distances, the third visual distance simulation state can be used to simulate intermediate visual distances between the first and second visual distances, and the second visual distance simulation state can be used to simulate relatively far visual distances.

[0102] In one possible implementation, the electronic device can first control the target display area to display according to a first display parameter, placing the target display area in a first visual distance simulation state; after the display duration of the first visual distance simulation state reaches T1, the electronic device controls the target display area to display according to a third display parameter, switching the target display area to a third visual distance simulation state; after the display duration of the third visual distance simulation state reaches T3, the electronic device controls the target display area to display according to a second display parameter, switching the target display area to a second visual distance simulation state; after the display duration of the second visual distance simulation state reaches T2, the electronic device can again control the target display area to switch back to the first visual distance simulation state. Thus, the target display area can be cyclically switched between the first visual distance simulation state, the third visual distance simulation state, and the second visual distance simulation state.

[0103] For example, the first visual distance simulation state can be a near visual distance simulation state, the third visual distance simulation state can be a medium visual distance simulation state, and the second visual distance simulation state can be a far visual distance simulation state. The first visual distance can be approximately 30cm, the third visual distance can be approximately 50cm, and the second visual distance can be approximately 5m to 10m. Correspondingly, T1 can be 2s, T3 can be 1s, and T2 can be 2s, thus forming a switching cycle of approximately 5s. The above visual distances and display durations are only examples; in actual applications, they can be adjusted according to the content displayed on the target interface, the size of the display screen, the eye use status of the viewed object, ambient light parameters, or user settings.

[0104] Optionally, when the target display area is in a second visual distance simulation state, the electronic device can still maintain the main content in the target display area at a preset readable clarity. That is, the electronic device can control the clarity parameter of the target display area to not be lower than a preset clarity threshold while reducing the spatial frequency parameter, edge sharpness parameter, or increasing the dot spread function parameter of the target display area, so as to avoid the main content in the target display area being unrecognizable.

[0105] In a specific implementation scenario, see Figure 7 , Figure 7 This is a schematic diagram illustrating another visual distance simulation state switching process provided in an embodiment of this application. For example... Figure 7 As shown, the electronic device can first initialize the display control parameters (or zoom parameters). The display control parameters may include at least one of the following: switching cycle, distance parameters corresponding to the visual distance simulation state, display parameter adjustment speed, and display duration corresponding to each visual distance simulation state.

[0106] The electronic device can first control the target display area to be in a simulated visual distance state corresponding to close-range focusing. This close-range focusing can be understood as a first visual distance simulation state, used to simulate a first visual distance. For example, the first visual distance can be 30cm. In the first visual distance simulation state, the target display area can be displayed according to first display parameters to maintain high clarity, high edge sharpness, and / or high spatial frequency in the target display area.

[0107] After the target display area reaches the first display duration according to the first display parameters, the electronic device can control the target display area to switch to the visual distance simulation state corresponding to the mid-range focus through stepless smooth zoom, avoiding abruptness. This mid-range focus can be understood as a third visual distance simulation state, used to simulate a third visual distance. For example, the third visual distance can be 50cm. It should be noted that the stepless smooth switching in this application can be understood as continuously adjusting at least one of the following parameters of the target display area: sharpness parameter, edge sharpness parameter, spatial frequency parameter, dot spread function parameter, blur parameter, brightness parameter, and contrast parameter, so as to smoothly transition the target display area between different visual distance simulation states.

[0108] After the target display area has been in the third visual distance simulation state for a certain duration, the electronic device can continue to control the target display area to switch to the visual distance simulation state corresponding to the distant focus through stepless smooth zoom. This distant focus can be understood as the second visual distance simulation state, used to simulate the second visual distance. For example, the second visual distance can be 5m to 10m. The first visual distance, third visual distance, and second visual distance can satisfy the following: the first visual distance is less than the third visual distance, and the third visual distance is less than the second visual distance. It should be noted that the focusing or zooming in this application can be understood as forming different visual distance simulation states through changes in display parameters, and is not limited to changing the actual optical focal length.

[0109] After the target display area is in the second visual distance simulation state, the electronic device can perform fatigue / distance detection. Fatigue / distance detection may include eye fatigue level detection and / or eye distance detection. The eye fatigue level can be determined based on the eye state data of the viewed object, which may include at least one of fixation point information, pupil change information, and blink frequency information. Eye distance can be used to characterize the distance between the viewed object and the display screen. Optionally, the electronic device can also acquire the eye distance between the viewed object and the display screen. The eye distance can be determined by an infrared sensor, a front-facing camera, a depth sensor, or other distance detection modules. When the eye distance is less than a preset distance threshold, the electronic device can adjust at least one of the display parameter update conditions, a first display parameter, a second display parameter, and a third display parameter. For example, when the eye distance is less than 30cm, the electronic device can increase the proportion of display time for the visual distance simulation state with a larger visual distance, or control the target display area to display according to the display parameters corresponding to the visual distance simulation state with a larger visual distance for a preset duration. The 30cm mentioned above is only an example; the preset distance threshold can be adjusted according to the display screen size, the age of the viewed object, user settings, or the display scenario.

[0110] If the fatigue / distance detection result is normal, the electronic device can control the target display area to return to the first visual distance simulation state and continue to cycle through the first visual distance simulation state, the third visual distance simulation state, and the second visual distance simulation state. If the fatigue / distance detection result indicates that the viewed object is fatigued and / or the distance is too close, the electronic device can enter the forced distant viewing mode. The forced distant viewing mode can be understood as: for a preset duration, controlling the target display area to display according to the display parameters corresponding to the visual distance simulation state with a larger visual distance. For example, the target display area can be controlled to display according to the display parameters simulating a visual distance of 8m to 10m and maintained for 30 seconds. The above visual distance, display duration, and preset duration are only examples and can be adjusted according to the display scenario, the viewing object's eye status, ambient light parameters, or user settings.

[0111] Optionally, when the viewing distance is less than a preset distance threshold, the electronic device can also increase the blur parameter of the non-target display area or decrease the edge sharpness parameter of the non-target display area to deepen the blurring of the background display area. Thus, the electronic device can reduce visual interference from the background display area on the viewed object while simultaneously switching between visual distance simulation states in the target display area.

[0112] In one possible implementation, the first display parameter or any of the second display parameters includes at least one of a sharpness parameter, an edge sharpness parameter, a spatial frequency parameter, a dot spread function parameter, a blur parameter, a brightness parameter, and a contrast parameter. Specifically, the sharpness parameter characterizes the overall sharpness of the target display area; the edge sharpness parameter characterizes the sharpness of image or text edges in the target display area; the spatial frequency parameter characterizes the frequency characteristics of detail textures or edge variations in the target display area; the dot spread function parameter characterizes the diffusion degree of pixels or image edges; the blur parameter characterizes the blur degree of the target display area; and the brightness and contrast parameters are used to adjust the brightness and contrast of the target display area.

[0113] Different visual distance simulation states can be characterized by differences between different display parameters. For example, when the edge sharpness parameter in the first display parameter is greater than the edge sharpness parameter in the second display parameter, and / or the spatial frequency parameter in the first display parameter is greater than the spatial frequency parameter in the second display parameter, and / or the point spread function parameter in the first display parameter is less than the point spread function parameter in the second display parameter, it can be considered that the first visual distance simulated by the first visual distance simulation state corresponding to the first display parameter is less than the second visual distance simulated by the second visual distance simulation state corresponding to the second display parameter.

[0114] In other words, under the first visual distance simulation state, the target display area can exhibit relatively higher edge sharpness, higher spatial frequency, and / or lower dot spread to simulate the display state at a closer visual distance. Under the second visual distance simulation state, the target display area can exhibit relatively lower edge sharpness, lower spatial frequency, and / or higher dot spread to simulate the display state at a farther visual distance.

[0115] For example, the first visual distance simulation state can be a near-field visual distance simulation state, and the second visual distance simulation state can be a far-field visual distance simulation state. The near-field visual distance simulation state can correspond to a virtual display distance of approximately 30cm, and the far-field visual distance simulation state can correspond to a virtual display distance of approximately 5m to 10m. In the near-field visual distance simulation state, the electronic device can increase the contrast parameters, edge sharpness parameters, and / or spatial frequency parameters of the target display area. In the far-field visual distance simulation state, the electronic device can decrease the spatial frequency parameters of the target display area and increase the dot spread function parameters and / or blur parameters to make the target display area present different visual distance simulation states.

[0116] Optionally, electronic devices can simulate different visual distances by coordinating the adjustment of edge sharpness parameters, spatial frequency parameters, and dot spread function parameters. For example, when simulating closer visual distances, the edge sharpness and spatial frequency parameters are increased, while the dot spread function parameter is decreased; when simulating farther visual distances, the edge sharpness and spatial frequency parameters are decreased, while the dot spread function parameter is increased. Through these differences in parameter sets, the target display area can present different display effects for perceived distances.

[0117] In this embodiment, a target interface is displayed on a display screen. The target display area within this interface is displayed on the screen according to first display parameters. This target display area includes the area of ​​interest to the browsing object on the display screen. When the display parameter update condition is met, the target display area is controlled to be displayed on the screen according to second display parameters. The first and second display parameters correspond to different visual distance simulation states. This reduces visual fatigue caused by prolonged viewing at a fixed distance while maintaining visibility of the main content.

[0118] As an example, a specific implementation scenario is described below.

[0119] See Figure 8 , Figure 8 This is a schematic diagram of a display control system provided in an embodiment of this application. Figure 8 As shown, in one possible implementation, the electronic device may include at least one of the following: a main control unit, a time-series zoom algorithm module, an AI semantic recognition module (also known as an AI content recognition module), an eye tracking module, an eye fatigue detection module, an ambient light sensor, a red light supplement module, a key area marking module, a dynamic focus driving module, and a display panel.

[0120] The main control unit can be used to schedule and control each module. The temporal zoom algorithm module can be used to determine the temporal parameters for switching the target display area between different visual distance simulation states, such as at least one of the following: a first display duration corresponding to a first display parameter, a second display duration corresponding to a second display parameter, and a third display duration corresponding to a third display parameter. The AI ​​semantic recognition module can be used to perform content recognition on the displayed content in the target interface to determine the region of interest in the target interface; therefore, it can also be called a content recognition module. The key area marking module can be used to mark key areas in the target interface based on the recognition results of the AI ​​semantic recognition module, and use the marked key areas as the target display area. For example, the AI ​​semantic recognition module can recognize displayed content such as text, people, objects, game characters, and interactive controls in the target interface based on at least one of the following: machine learning model, deep learning model, neural network model, semantic segmentation model, object detection model, and saliency detection model.

[0121] The dynamic focus driving module can be used to control the target display area in the display panel to display according to a first display parameter, a second display parameter, or a third display parameter, based on control commands output by the main control unit or the timing zoom algorithm module. It should be noted that the dynamic focus driving module in this embodiment can be understood as a driving module used to adjust the display parameters of the target display area. It can adjust at least one of the following parameters: sharpness parameter, edge sharpness parameter, spatial frequency parameter, dot spread function parameter, blur parameter, brightness parameter, and contrast parameter, to make the target display area present different visual distance simulation states, and is not limited to changing the physical focal length through mechanical or optical structures.

[0122] The eye-tracking module can be used to acquire images of the eyes of the viewed object, or to determine gaze point information based on the eye images. The eye fatigue detection module can be used to determine the eye fatigue level of the viewed object based on at least one of gaze point information, pupil change information, and blink frequency information. The ambient light sensor can be used to acquire ambient light brightness and / or ambient light color temperature. The 650nm red light supplementary lighting module can be used as a specific implementation of the supplementary lighting module, to output light within a preset wavelength range to supplement the target interface when the target display area is displayed according to display parameters corresponding to a larger visual distance. The display panel is used to display the target interface and the target display area updated according to different display parameters.

[0123] Therefore, the main control unit can control the dynamic focus drive module to adjust the display parameters of the target display area in the display panel based on at least one of the following: the target display area determined by the AI ​​semantic recognition module, the switching sequence determined by the time-series zoom algorithm module, the eye use status determined by the eye tracking module and the eye fatigue detection module, and the ambient light parameters determined by the ambient light sensor. This allows the target display area to switch between different simulated visual distance states. It should be noted that focusing or zooming in this application can be understood as forming different simulated visual distance states through changes in display parameters, and is not limited to changing the actual optical focal length.

[0124] In one possible implementation, if the first visual distance simulated by the first visual distance simulation state corresponding to the first display parameter is less than the second visual distance simulated by the second visual distance simulation state corresponding to the second display parameter, then when controlling the target display area to be displayed on the display screen according to the second display parameter, the fill light module in the display screen is controlled to output light within a preset wavelength range to fill light on the target interface.

[0125] In one possible implementation, the electronic device may include a fill light module, which may be disposed in the display screen. Exemplarily, the fill light module may be disposed in the backlight layer of the display screen, the display module, the screen peripheral structure, or other locations capable of providing fill light to the target interface; this application embodiment does not limit this.

[0126] If the first visual distance simulated by the first visual distance simulation state corresponding to the first display parameter is less than the second visual distance simulated by the second visual distance simulation state corresponding to the second display parameter, then the second visual distance simulation state corresponding to the second display parameter can be considered as simulating a relatively far visual distance. When the electronic device controls the target display area to be displayed on the display screen according to the second display parameter, the electronic device can control the supplementary lighting module in the display screen to output light within a preset wavelength range to supplement the target interface.

[0127] The preset wavelength range can be determined based on the simulated visual distance of the target display area, the displayed content of the target interface, ambient light parameters, or the eye usage status of the viewed object. For example, the preset wavelength range may include the wavelength range corresponding to long-wavelength light, such as 620nm to 700nm; in some examples, the preset wavelength range may include the wavelength range around 650nm. The above wavelength ranges are merely examples, and this application embodiment does not limit the supplementary lighting module to output light of a fixed wavelength.

[0128] In one possible implementation, the electronic device can control the supplementary lighting module to synchronously output light within a preset wavelength range when the target display area switches from a first visual distance simulation state to a second visual distance simulation state. Alternatively, the electronic device can also control the supplementary lighting module to output light within a preset wavelength range during at least a portion of the display period displayed in the target display area according to the second display parameters.

[0129] In one possible implementation, the supplementary lighting parameters of the supplementary lighting module may include at least one of supplementary lighting wavelength, supplementary lighting intensity, supplementary lighting duration, and supplementary lighting frequency. The electronic device can determine the supplementary lighting parameters of the supplementary lighting module based on at least one of a second display parameter, ambient light brightness, ambient light color temperature, eye fatigue level, and the display duration of the target display area according to the second display parameter.

[0130] For example, when the ambient light is low, or when the eye fatigue level of the viewed object reaches a preset level, the electronic device can increase the supplementary lighting frequency of the supplementary lighting module or extend the supplementary lighting duration. When the ambient light is high, the electronic device can reduce the supplementary lighting intensity of the supplementary lighting module or shorten the supplementary lighting duration. In this way, the supplementary lighting module can cooperate with the visual distance simulation state switching process of the target display area to achieve supplementary lighting control of the target interface.

[0131] In one possible implementation, the electronic device can determine the display control method for the target display area based on the user mode. The user mode can include at least one of a child mode, an adult office mode, an elderly mode, and a professional office mode. In child mode, the electronic device can increase the proportion of display time in simulated visual distance states with larger visual distances, or shorten the switching cycle between different simulated visual distance states for the target display area. In adult office mode, the electronic device can adjust edge sharpness parameters, clarity parameters, and switching cycle based on the displayed text content. In elderly mode, the electronic device can increase the clarity or contrast parameters of the target display area. In professional office mode, the electronic device can control the target display area to switch from a first simulated visual distance state to a second simulated visual distance state only after a preset period of inactivity has been detected.

[0132] In one possible implementation, the electronic device can also collect statistics on usage data during the display control process to obtain display control statistics. These statistics may include at least one of the following: viewing time of the object being viewed, number of times the target display area is switched, cumulative display time in the first visual distance simulation state, cumulative display time in the second visual distance simulation state, cumulative display time in the third visual distance simulation state, number of times eye fatigue levels reach a preset level, number of times the supplementary lighting module activates supplementary lighting, and supplementary lighting duration.

[0133] Electronic devices can generate prompts or reports based on display control statistics. These prompts or reports can indicate at least one of the following: viewing time duration, visual distance simulation status switching, changes in eye fatigue level, and the operational status of the supplementary lighting module. The electronic device can display these prompts or reports locally or send them to an external terminal.

[0134] For example, the external terminal can be a mobile phone, tablet, smartwatch, parental control terminal, management terminal, or server. The electronic device can send display control statistics, prompts, or reports to the external terminal via wireless or wired communication, so that the browsing object or management user can view the viewing status and display control status of the target interface.

[0135] In one possible implementation, the electronic device may have at least one of a basic display control implementation, a first extended display control implementation, and a second extended display control implementation.

[0136] In the basic display control implementation, the electronic device may include a display screen, a processor, a display driver module, a content recognition module, and a timing zoom algorithm module. The content recognition module can be used to determine the target display area in the target interface, the timing zoom algorithm module can be used to determine the display duration and switching order of the target display area when switching between the first visual distance simulation state, the second visual distance simulation state, and / or the third visual distance simulation state, and the display driver module can be used to adjust the display parameters of the target display area according to the display control instructions output by the processor.

[0137] In the first extended display control implementation, the electronic device may further include an eye-tracking module, an eye fatigue detection module, and / or an eye-distance detection module. The eye-tracking module can be used to determine the gaze point information of the viewed object; the eye fatigue detection module can be used to determine the eye fatigue level based on at least one of the gaze point information, pupil change information, and blink frequency information; and the eye-distance detection module can be used to determine the eye-distance between the viewed object and the display screen. The electronic device can adjust at least one of the display parameter update conditions, a first display parameter, a second display parameter, and a third display parameter based on the eye fatigue level and / or eye-distance.

[0138] In the second extended display control implementation, the electronic device may further include an ambient light detection module, a supplementary lighting module, and a user mode determination module. The ambient light detection module can be used to acquire ambient light brightness and / or ambient light color temperature; the supplementary lighting module can be used to output light within a preset wavelength range when displaying the target display area according to the display parameters corresponding to the simulated state with a larger visual distance; and the user mode determination module can be used to determine the user mode corresponding to the browsing object.

[0139] For example, the user mode may include at least one of the following: child mode, adult office mode, senior mode, and professional office mode. In child mode, the electronic device may increase the display time of the simulated visual distance state with a larger visual distance, for example, adjust it to 60%, and adjust the switching cycle to 4 seconds; in adult office mode, the electronic device may adjust the display time of the simulated visual distance state with a larger visual distance to 40%, and adjust the switching cycle to 5 seconds; in senior mode, the electronic device may increase the clarity or contrast parameters of the target display area, for example, increase the clarity parameter of the target display area by 20%; in professional office mode, the electronic device may control the target display area to switch from the first simulated visual distance state to the second simulated visual distance state after detecting that there is no operation for a preset time. For example, the preset time may be 3 seconds. The above values ​​are only examples, and the embodiments of this application are not limited thereto. Optionally, in child mode, the electronic device may also limit the maximum brightness of the display screen and / or enable the posture detection function. The posture detection function may be implemented based on a front-facing camera, an infrared sensor, a depth sensor, or other posture detection modules. Electronic devices can adjust display parameter update conditions, the display duration of the second visual distance simulation state, or prompt information based on the posture detection results.

[0140] In one possible implementation, the electronic device can also adjust the supplementary lighting parameters of the supplementary lighting module according to the ambient light parameters. For example, when the ambient light intensity is greater than or equal to 500 lux, the electronic device can adjust the brightness parameters, contrast parameters, or the proportion of display time for a simulated visual distance state with a large visual distance in the target display area; when the ambient light intensity is less than 500 lux, the electronic device can reduce the brightness parameters of the target interface, adjust the color temperature parameters of the target interface, or increase the supplementary lighting frequency of the supplementary lighting module. For example, the supplementary lighting module can provide supplementary lighting at preset intervals, such as 1 second of supplementary lighting every 10 seconds, or 1 second of supplementary lighting every 15 seconds. The 500 lux, 10 seconds, 15 seconds, and 1 second mentioned above are merely examples, and this application embodiment does not limit them. Optionally, the electronic device can control the supplementary lighting intensity of the supplementary lighting module to not exceed a preset brightness threshold to reduce the impact of supplementary lighting on the normal display of the target interface. For example, the preset brightness threshold can be 50 cd / m², or it can be determined according to the display screen type, ambient light parameters, or user mode.

[0141] In one possible implementation, the electronic device can also statistically analyze usage data during the display control process to obtain display control statistics. These statistics may include at least one of the following: eye usage time of the viewed object, number of times the target display area is switched, cumulative display time in the first visual distance simulation state, cumulative display time in the second visual distance simulation state, cumulative display time in the third visual distance simulation state, number of times eye fatigue levels reach a preset level, number of times the supplementary lighting module activates supplementary lighting, and supplementary lighting duration. The electronic device can generate prompts or reports based on the display control statistics and can display these prompts or reports locally or send them to an external terminal. The external terminal may include at least one of a mobile phone, tablet computer, smartwatch, parental control terminal, management terminal, or server.

[0142] See Figure 9 , Figure 9 A comparative schematic diagram of three specific embodiments provided for the present application.

[0143] like Figure 9 As shown, the electronic device or display control system provided in this application embodiment can be implemented in three ways: a basic version, an advanced version, and a high-end version, depending on the hardware configuration, application scenario, and functional requirements. The basic version can be used to implement basic display control functions; the advanced version can add human eye state detection and eye distance monitoring functions on the basis of the basic version; and the high-end version can further add ambient light perception, supplementary lighting linkage, and multi-person mode adaptation functions on the basis of the advanced version.

[0144] The basic version can include AI semantic recognition, dynamic zone focusing, and temporal zoom. AI semantic recognition can be used to identify the displayed content in the target interface to determine the target display area. For example, AI semantic recognition can identify at least one of text areas, character areas, object areas, game character areas, and interactive control areas, and determine the area that the browsing object is primarily focused on or interested in as the target display area. Dynamic zone focusing can be used to differentiate the display control of different display areas in the target interface. For example, the electronic device can control the target display area to display according to a first display parameter, a second display parameter, or a third display parameter, and can control non-target display areas to display according to a weakening parameter or a blurring parameter. Temporal zoom can be used to control the target display area to switch between simulated states at different visual distances according to a preset time sequence. Dynamic zone focusing and temporal zoom can be understood as adjusting display parameters through at least one of sharpness parameters, edge sharpness parameters, spatial frequency parameters, dot spread function parameters, blur parameters, brightness parameters, and contrast parameters, and are not limited to changing the actual physical focal length through mechanical or optical structures.

[0145] The advanced version includes all the functions of the basic version, and further includes eye tracking, eye fatigue detection, and viewing distance monitoring. The basic version's functions include AI semantic recognition, dynamic zone focusing, and temporal zoom. Eye tracking can be used to acquire images of the viewed object's eyes and determine gaze point information based on these images. Eye fatigue detection can determine the level of eye fatigue based on the viewed object's eye usage data. Eye usage data can include at least one of gaze point information, pupil change information, and blink frequency information. Viewing distance monitoring can detect the distance between the viewed object and the display screen. The electronic device can adjust display parameter update conditions, first display parameters, second display parameters, third display parameters, the proportion of display time for simulated visual distances with larger visual distances, or the switching cycle of the target display area based on at least one of the eye tracking results, eye fatigue detection results, and viewing distance monitoring results. Therefore, the advanced version can perform adaptive display control based on the actual eye usage status of the viewed object, building upon the basic display control functions.

[0146] The high-end version includes all the features of the advanced version, and further includes a pixel-level focus panel, an ambient light sensor, a red light myopia intervention module, and customized modes for multiple user groups. The advanced version's full functionality includes all the features of the basic version, eye tracking, eye fatigue detection, and viewing distance monitoring. A pixel-level focus panel can be understood as a display panel capable of supporting pixel-level or pixel-area-level display parameter control. For example, electronic devices can adjust at least one of the following parameters of the target display area based on pixels or pixel areas: sharpness, edge sharpness, spatial frequency, dot spread function, blur, brightness, and contrast, to simulate different visual distances in the target display area. It should be noted that "focusing" in a pixel-level focus panel can be understood as pixel-level or pixel-area-level display parameter control, and is not limited to actually changing the physical focal plane of the display screen.

[0147] An ambient light sensor can be used to detect ambient light parameters. Ambient light parameters may include at least one of ambient light brightness and ambient light color temperature. Electronic devices can adjust the brightness, contrast, color temperature, supplementary lighting, or switching parameters of the visual distance simulation state of the target display area based on the ambient light parameters detected by the ambient light sensor. A red light myopia intervention module can be a specific implementation of the supplementary lighting module, used to output light within a preset wavelength range. For example, the preset wavelength range may include 620nm to 700nm, or a wavelength range around 650nm. Here, the red light myopia intervention module can be understood as a red light supplementary lighting module that works in conjunction with the visual distance simulation state switching process. It can output light during at least a portion of the display period when the target display area is in a visual distance simulation state with a large visual distance, to supplement the display light corresponding to the target interface, and is not limited to producing a medical treatment effect.

[0148] Multi-user customization modes can be used to determine different display control strategies based on the type of browsing object or user settings. For example, multi-user customization modes may include at least one of a children's mode, an adult office mode, a senior citizen mode, and a professional office mode. In children's mode, the electronic device can increase the proportion of display time in simulated visual distance states with larger viewing distances, or shorten the switching cycle between different simulated visual distance states of the target display area. In adult office mode, the electronic device can adjust edge sharpness parameters, clarity parameters, and switching cycle according to the displayed content of the text area. In senior citizen mode, the electronic device can increase the clarity parameters or contrast parameters of the target display area. In professional office mode, the electronic device can control the target display area to switch to a simulated visual distance state with a larger viewing distance only after a preset period of inactivity has been detected.

[0149] Therefore, through Figure 9 The three implementation schemes shown in this application—basic, advanced, and high-end—can be functionally expanded according to the hardware configuration and application requirements of different electronic devices. Specifically, the basic version can achieve AI semantic recognition, dynamic zone focusing, and time-series zoom without adding complex sensors; the advanced version, based on all the functions of the basic version, combines eye tracking, eye fatigue detection, and viewing distance monitoring to achieve closed-loop display control; and the high-end version, based on all the functions of the advanced version, combines a pixel-level focusing panel, an ambient light sensor, a red light myopia intervention module, and multi-user customized modes to achieve more refined display control.

[0151] like Figure 10As shown, the display control device 1000 includes: Display unit 1001 is used to display a target interface on a display screen. The target display area in the target interface is displayed on the display screen according to a first display parameter. The target display area includes the area of ​​interest to the browsing object on the display screen. The control unit 1002 is used to control the target display area to be displayed on the display screen according to the second display parameters when the display parameter update conditions are met; The first display parameter and the second display parameter respectively correspond to different visual distance simulation states.

[0152] In one possible implementation, the first display parameter corresponds to a first visual distance simulation state, the second display parameter corresponds to a second visual distance simulation state, and the target display area switches between the first visual distance simulation state and the second visual distance simulation state.

[0153] In one possible implementation, the first display parameter or any of the second display parameters includes at least one of the following: sharpness parameter, edge sharpness parameter, spatial frequency parameter, dot spread function parameter, blur parameter, brightness parameter, and contrast parameter. When the edge sharpness parameter in the first display parameter is greater than the edge sharpness parameter in the second display parameter, and / or the spatial frequency parameter in the first display parameter is greater than the spatial frequency parameter in the second display parameter, and / or the dot spread function parameter in the first display parameter is less than the dot spread function parameter in the second display parameter, the first visual distance simulated by the first visual distance simulation state corresponding to the first display parameter is less than the second visual distance simulated by the second visual distance simulation state corresponding to the second display parameter.

[0154] In one possible implementation, the condition for satisfying the display parameter update includes at least one of the following: The target display area displays for a duration equal to the first display duration in the first display parameter. The eye fatigue level of the browsing object has reached a preset level. The eye fatigue level is determined based on the browsing object's eye use status data. The eye use status data includes at least one of fixation point information, pupil change information, and blink frequency information. The eye use status data is determined based on the browsing object's eye image. The ambient light parameters reach a preset parameter threshold, which includes at least one of ambient light brightness and ambient light color temperature.

[0155] In one possible implementation, if the first visual distance simulated by the first visual distance simulation state corresponding to the first display parameter is less than the second visual distance simulated by the second visual distance simulation state corresponding to the second display parameter, then when controlling the target display area to be displayed on the display screen according to the second display parameter, the control unit 1002 is also used to control the supplementary light module in the display screen to output light within a preset wavelength range to supplement the target interface.

[0156] In one possible implementation, during the process of the target display area switching between the first visual distance simulation state and the second visual distance simulation state, the control unit 1002 is further configured to control the target display area to be displayed on the display screen according to the third display parameters; The third display parameter corresponds to a third visual distance simulation state. The third visual distance simulated by the third visual distance simulation state is greater than the first visual distance simulated by the first visual distance simulation state and less than the second visual distance simulated by the second visual distance simulation state. The target display area switches between the first visual distance simulation state, the third visual distance simulation state and the second visual distance simulation state.
