[0001] This application claims priority to Chinese Patent Application No. 202410328177.8, filed on March 21, 2024, the entire contents of which are incorporated herein by reference.TECHNICAL FIELD

[0002] The present application relates to the technical field of screen display, and in particular, to a screen display method, a screen display apparatus, a device, and a storage medium.BACKGROUND

[0003] With the development of display technology, more and more types of display devices have appeared in the market. Following Cathode Ray Tube (CRT) displays, Liquid Crystal Display (LCD) displays, and Light-Emitting Diode (LED) displays, Organic Light-Emitting Diode (OLED) displays have emerged. Since OLED display screens have advantages such as being light and thin, having a high color gamut, and high contrast, they are increasingly adopted by more and more television products.

[0004] OLED belongs to a current-type organic light-emitting device, and it produces a phenomenon of emitting light through the injection and recombination of charge carriers. The light-emitting intensity is directly proportional to the injected current, and the display principle is that organic materials emit fluorescence under the action of an electric field for display. In the usage process, the brightness of the pixel dots at the screen will slowly decay as the usage time increases. Limited by the display image, the brightness decay degrees of pixel dots at different positions are different. After a period of time, the brightness differences among the pixel dots at different positions will cause an image retention phenomenon, which is commonly referred to as burn-in.

[0033] Based on the above structure, various embodiments of the screen display method are provided.

[0034] Referring to FIG. 2, FIG. 2 is a flowchart schematic diagram of a first embodiment of the screen display method of the present application.

[0035] In this embodiment, an execution subject of the screen display method may be an electronic device. The electronic device may be a local device, such as a vehicle's central control system or an Electronic Control Unit (ECU), and may also be a network device, which is not limited in this embodiment. Hereinafter, for the convenience of description, the elaboration of each embodiment is performed by omitting the execution subject. In this embodiment, the screen display method is applied to a vehicle-mounted display screen. The screen display method includes: Step S10, dynamically obtaining a display image of a target display screen, the display image being displayed in a first display region of the target display screen; In a feasible embodiment, in order to effectively solve the burn-in problem existing in the OLED display screen, regions of the vehicle-mounted display screen are pre-divided to obtain an actual display region (namely, the first display region) configured to display the display image, and a to-be-displayed region (namely, the second display region) which is similarly capable of being configured to display the display image but with unoccupied pixels. Thus, the display image of each vehicle-mounted display screen is displayed in the first display region by default. To further determine whether the display screen has a burn-in risk, the display image of the target display screen is dynamically obtained.

[0036] The target display screen is any display screen among the vehicle-mounted display screens. For example, the vehicle-mounted display screens can be divided according to position, function, etc., and at least include: an instrument display screen, a central control display screen, an entertainment display screen, etc.

[0037] The number of the first display regions of the target display screen may be one or more. The plurality of first display regions may be adjacent or not adjacent. The number of the second display regions of the target display screen may be one or more. The plurality of second display regions may be adjacent or not adjacent.

[0038] Exemplarily, referring to FIG. 3, a resolution of the target display screen is X*Y, which means that all pixels X*Y are occupied during full-screen display. Further, the display region of the target display screen is divided to obtain a first display region A 1 , whose occupied pixel rate is (X-2m)*(Y-2n). The remaining unoccupied pixels constitute a second display region A 2 .

[0039] Exemplarily, referring to FIG. 4, a resolution of the target display screen is X*Y, which means that all pixels X*Y are occupied during full-screen display. Further, the display region of the target display screen is divided to obtain a first display region B 1 , whose occupied pixel rate is (X-2m)*Y. The remaining unoccupied pixels constitute a second display region B 2 .

[0040] Exemplarily, referring to FIG. 5, a resolution of the target display screen is X*Y, which means that all pixels X*Y are occupied during full-screen display. Further, the display region of the target display screen is divided to obtain a first display region C 1 , whose occupied pixel rate is X*(Y-2n). The remaining unoccupied pixels constitute two second display regions C 2 and C 3 .

[0041] Exemplarily, referring to FIG. 6, a resolution of the target display screen is X*Y, which means that all pixels X*Y are occupied during full-screen display. Further, based on a preset interface design of the target display screen, the display region is divided to obtain a plurality of first display regions (D 1 -D 5 ). The remaining unoccupied pixels constitute a second display region D 6 . Further, dynamically obtaining the display image of any first display region of the target display screen, and executing the step of controlling the display image to move toward the second display region of the target display screen in response to determining that the display image satisfies a preset static image movement condition.

[0042] In a feasible implementation mode, before step S20, controlling the display image to move toward the second display region of the target display screen in response to determining that the display image satisfies the preset static image movement condition, the method further includes:

[0043] Step S11, determining a pixel change rate of the display image within a preset continuous duration.

[0044] In a feasible embodiment, the pixel change rate of the display image within the preset continuous duration is calculated. The pixel change rate may be an average value of change rates of current frame pixel values of respective pixels in the display image relative to historical frame pixel values.

[0045] In an embodiment, the method further includes calculating an average value of adjacent frame pixel value differences of respective pixels between adjacent frames within the preset continuous duration, to serve as a first change rate corresponding to each of the pixels of the display image; and determining an average value of first change rates of pixels included in the display image as the pixel change rate.

[0046] Step S12, determining whether the pixel change rate is greater than a preset change rate threshold.

[0047] Step S13, in response to that the pixel change rate is greater than the preset change rate threshold, determining that the display image does not satisfy the static image movement condition.

[0048] Step S14, in response to that the pixel change rate is not greater than the preset change rate threshold, determining that the display image satisfies the static image movement condition.

[0049] In a feasible embodiment, determining whether the pixel change rate of the display image is greater than the preset change rate threshold. When the pixel change rate of the display image is greater than the preset change rate threshold, it indicates that the pixels of the display image as a whole are in a process of dynamic change, that is, the brightness is constantly changing, and the probability of burn-in occurrence is relatively low, then it is determined that the display image does not satisfy the static image movement condition, and the step of dynamically obtaining the display image of the target display screen is performed. When the pixel change rate of the display image is not greater than the preset change rate threshold, it indicates that the pixels of the display image as a whole are in a relatively still state, and at least some pixels stay lit for a long time and the brightness remains unchanged. If this is maintained continuously, the target display screen may experience a burn-in situation, that is, there is a burn-in risk. Then, it is determined that the display image satisfies the static image movement condition.

[0050] In this embodiment, the pixel change rate of the display image within the preset continuous duration is determined, to further determine whether the pixel change rate is greater than the preset change rate threshold. When the pixel change rate is greater than the preset change rate threshold, it indicates that the pixels of the display image as a whole are in a process of dynamic change, and the probability of burn-in occurrence is relatively low, then to determine that the display image does not satisfy the static image movement condition. When the pixel change rate is not greater than the preset change rate threshold, it indicates that the pixels of the display image as a whole are in a relatively still state and there is a burn-in risk, then to determine that the display image satisfies the static image movement condition. Through the pixel change rate of the display image, the determination accuracy for the burn-in risk of the target display screen is improved, and corresponding measures can be executed in a timely manner to avoid the burn-in phenomenon at the vehicle-mounted display screen.

[0051] Step S20, in response to determining that the display image satisfies the preset static image movement condition, controlling the display image to move toward a second display region of the target display screen. The second display region includes a plurality of unoccupied pixels configured to display the display image.

[0052] In a feasible embodiment, the static image movement condition includes: the pixel change rate of the display image within the preset continuous duration is less than or equal to the preset change rate threshold. If the pixel change rate of the display image within the preset continuous duration is less than or equal to the preset change rate threshold, then the display image satisfies the static image movement condition. Further, controlling the display image to move toward the unoccupied pixel region (the second display region) reserved in the target display screen, so as to achieve pixel-level jumping of the display image within the target display screen.

[0053] Exemplarily, referring to FIG. 7, in response to determining that the display image A 1 satisfies the preset static image movement condition, controlling the display image A 1 to move toward the second display region A 2 of the target display screen, so that the display image A 1 moves from a center of the target display screen toward the left side.

[0054] It should be understood that, since the target display screen is a vehicle-mounted display screen provided at a vehicle, a viewer located inside the vehicle may not necessarily concentrate on watching the target display screen for a long time. That is, the viewer's sensitivity to the display image of the vehicle-mounted display screen will be far lower than that of devices such as televisions and computers. Therefore, when the display image satisfies the preset static image movement condition, when controlling the display image to move, if the movement speed is set properly, the user's viewing experience will not be affected.

[0055] In this embodiment, through the pre-division of the display regions of the vehicle-mounted display screen, an actual display region (namely, the first display region) configured to display the display image, as well as a to-be-displayed region (namely, the second display region) similarly capable of being configured to display the display image but with unoccupied pixels, are obtained. Further, in response to determining that the display image satisfies the preset static image movement condition, that is, when at least a part of the static image exists in the display image and there is a certain burn-in risk, automatically controlling the display image to move toward the second display region reserved in the target display screen. Since one of the reasons for the burn-in situation of the OLED display screen is that the pixel dots at the display screen stay lit for a long time and the brightness remains unchanged, thereby resulting in different brightness decay degrees of each pixel dot at the display screen. Therefore, through the pre-division of regions, a movable region is provided for the display image. Further, when a burn-in risk exists, that is, the preset static image movement condition is satisfied, the display image is controlled to move within the second display region of the target display screen; so that at least some pixels of the target display screen have a change in brightness caused by the movement, thereby effectively avoiding the occurrence of the burn-in situation of the display screen.

[0056] Further, based on the first embodiment, a second embodiment of the screen display method of the present application is provided. In this embodiment, step S20, controlling the display image to move toward the second display region of the target display screen includes:

[0057] Step S21, generating a plurality of movement paths for the display image moving toward the second display region according to a pixel quantity of the first display region and a pixel quantity of the second display region.

[0058] In a feasible embodiment, in order to avoid the occurrence of a display screen burn-in situation through page movement; generating a plurality of paths (hereinafter referred to as movement paths for differentiation) for the display image to move toward the second display region according to the numbers of pixels included in the first display region and the second display region.

[0059] In an embodiment, the movement path includes a path of the display image moving within the second display region.

[0060] Step S22, determining a movement pixel change rate of the display image moving based on each movement path.

[0061] Step S23, determining a target path among the movement paths according to the movement pixel change rate, the target path being a movement path corresponding to a maximum value of the movement pixel change rate.

[0062] Step S24, controlling the display image to move toward the second display region based on the target path.

[0063] In a feasible embodiment, after generating the plurality of movement paths, it is further necessary to select a suitable target path from the plurality of movement paths; then, simulate and calculate the movement pixel change rate of the display image when moving based on each movement path; then determine the movement path corresponding to the maximum value of the movement pixel change rate as the target path. If the plurality of movement paths have the same movement pixel change rate and all are the maximum value, then any one of the movement paths is selected as the target path. Control the display image to move toward the second display region based on the target path.

[0064] In this embodiment, through generating the plurality of movement paths for the display image moving toward the second display region according to the pixel quantities of the first display region and the second display region; and then determining the movement pixel change rate of the display image moving based on each movement path; further, according to the movement pixel change rate, a suitable target path is selected from the plurality of movement paths, which is the movement path corresponding to the maximum value of the movement pixel change rate; and then controlling the display image to move toward the second display region based on the target path; so that when the display image moves based on the target path, the pixels of the target display screen can be changed to the greatest extent, thereby further reducing the occurrence probability of the burn-in situation of the vehicle-mounted display screen.

[0065] In a feasible implementation mode, the target display screen is provided with an eye tracking module. Step S20, controlling the display image to move toward the second display region of the target display screen includes: Step S25, obtaining a first quantity of visual gaze points of the target display screen collected by the eye tracking module.

[0066] In a feasible embodiment, each vehicle-mounted display screen is provided with an eye tracking module, which is configured to collect a visual gaze point generated at the vehicle-mounted display screen when a user gazes at the vehicle-mounted display screen; and obtaining the first quantity of visual gaze points of the target display screen collected by the eye tracking module.

[0067] Step S26, determining a target movement speed of the display image according to the first quantity of the visual gaze points. The first quantity of the visual gaze points is negatively correlated with the target movement speed.

[0068] In a feasible embodiment, according to the first quantity of visual gaze points of the target display screen, determining a suitable target movement speed during the movement of the display image. The first quantity of the visual gaze points is negatively correlated with the target movement speed. Because the more the visual gaze points of the target display screen are, the more users are indicated to be gazing at the target display screen. If it moves fast at this time, the visual experience of the users will be affected; therefore, the movement speed of the display image needs to be reduced. If the visual gaze points of the target display screen are fewer, it indicates that the user may not be focusing on the display image of the target display screen at this time. Then at this time, the display image is controlled to speed up the movement speed, so that the pixels of the target display screen generate a brightness change, thereby reducing the burn-in risk of the display screen.

[0069] In a feasible implementation mode, step S26, determining the target movement speed of the display image according to the first quantity of the visual gaze points includes:

[0070] Step S261, determining whether the first quantity of the visual gaze points is zero;

[0071] Step S262, when the first quantity of the visual gaze points is not zero, obtaining the target movement speed corresponding to the first quantity of the visual gaze points according to a preset mapping relationship between a visual gaze point quantity and an image movement speed.

[0072] Step S263, when the first quantity of the visual gaze points is zero, determining the target movement speed according to a first continuous duration during which the first quantity of the visual gaze points is zero. The first continuous duration is positively correlated with the target movement speed.

[0073] In a feasible embodiment, whether the first quantity of visual gaze points of the target display screen is zero is determined. When the first quantity of the visual gaze points is not zero, it indicates that there are still some users currently gazing at the target display screen, then obtaining the target movement speed corresponding to the first quantity of the visual gaze points according to a preset mapping relationship between a visual gaze point quantity and an image movement speed. When the first quantity of the visual gaze points is zero, it indicates that no user is gazing at the target display screen at this time, but this may be because the user needs to observe traffic conditions during vehicle driving and briefly shifts his / her sight from the target display screen. If the display screen is moved rapidly immediately, it may still affect the viewing experience of the user. Therefore, further obtaining the first continuous duration during which the first quantity of visual gaze points is zero, and determining the target movement speed according to the first continuous duration. The first continuous duration is positively correlated with the target movement speed. When the first continuous duration is relatively short, the display image is controlled to move at a lower speed to cope with the scenario where the user merely briefly does not gaze at the target display screen. As the first continuous duration during which the first quantity of the visual gaze points is zero continues to increase, it indicates that the user is not briefly shifting his / her sight, but has no usage requirement for the target display screen within a certain period of time. Then the movement speed of the display image is increased to achieve a better effect of avoiding the occurrence of the display screen burn-in situation.

[0074] In an embodiment, determining the target movement speed according to the first continuous duration during which the first quantity of the visual gaze points is zero includes: determining a target duration interval among preset duration intervals in which the first continuous duration is located; taking a movement speed associated with the target duration interval as the target movement speed.

[0075] In an embodiment, determining the target movement speed according to the first continuous duration during which the first quantity of the visual gaze points is zero includes: obtaining the target movement speed corresponding to the first continuous duration according to a preset mapping relationship between a zero-gaze continuous duration and the image movement speed.

[0076] Step S27, controlling the display image to move toward the second display region based on the target movement speed.

[0077] In a feasible embodiment, after determining the target movement speed, controlling the display image to move toward the second display region at the target movement speed.

[0078] In this embodiment, based on a vehicle-mounted scenario of the vehicle-mounted display screen, a viewing user of the vehicle-mounted display screen has a lower sensitivity to the display image in the display screen than to other display devices, such as televisions and computers. Therefore, when controlling the display image to move, the target movement speed can be determined through the first quantity of the visual gaze points of the target display screen collected by the eye tracking module. The first quantity of the visual gaze points is negatively correlated with the target movement speed. Thus, on the basis of ensuring the user's use experience, the occurrence of the burn-in phenomenon of the display screen is effectively avoided.

[0079] Further, based on the above first and / or second embodiments, a third embodiment of the screen display method of the present application is provided. In this embodiment, the target display screen is provided with an eye tracking module. After Step S20, controlling the display image to move toward the second display region of the target display screen, the method further includes:

[0080] Step S30, obtaining a second quantity of visual gaze points of the target display screen collected by the eye tracking module.

[0081] In a feasible embodiment, each vehicle-mounted display screen is provided at an eye tracking module, which is configured to collect a visual gaze point generated at the vehicle-mounted display screen when a user gazes at the vehicle-mounted display screen. After controlling the display image to move, continuing to obtain the second quantity of the visual gaze points of the target display screen collected by the eye tracking module.

[0082] Step S40, when the second quantity of the visual gaze points is zero, determining a target brightness reduction rate of the target display screen according to a second continuous duration during which the second quantity of the visual gaze points is zero. The second continuous duration is positively correlated with the target brightness reduction rate;

[0083] Since long-term high brightness of the display screen is also one of the causes of the burn-in phenomenon of the display screen, therefore, the display brightness can be properly reduced according to the user's usage situation of the display screen, to avoid the occurrence of the display screen burn-in situation. In order to avoid affecting the user experience caused by the reduction of the display brightness, an automatic reduction of the target display screen brightness is performed when the second quantity of the visual gaze points is zero.

[0084] In a feasible embodiment, when the second quantity of the visual gaze points is zero, then determining a target brightness reduction rate of the target display screen according to the second continuous duration during which the second quantity of the visual gaze points is zero. The second continuous duration is positively correlated with the target brightness reduction rate.

[0085] In a feasible implementation mode, step S40, determining the target brightness reduction rate of the target display screen according to the second continuous duration during which the second quantity of the visual gaze points is zero includes: Step S41, obtaining the target brightness reduction rate corresponding to the second continuous duration according to a preset mapping relationship between a zero-gaze continuous duration and a brightness reduction rate.

[0086] In a feasible embodiment, there is a preset mapping relationship between the zero-gaze continuous duration and the brightness reduction rate. The zero-gaze continuous duration is a continuous duration when the quantity of the visual gaze points of the display screen is zero. Based on the above mapping relationship, matching to obtain the target brightness reduction rate corresponding to the second continuous duration.

[0087] Step S50, controlling the target display screen to gradually reduce a display brightness based on the target brightness reduction rate.

[0088] In a feasible embodiment, after a suitable target brightness reduction rate is determined, controlling the target display screen to gradually reduce the display brightness based on the target brightness reduction rate.

[0089] In an embodiment, the target display screen is provided with a temperature sensor; and display temperature data of the target display screen collected by the temperature sensor is dynamically obtained. If the display temperature data is greater than a preset temperature threshold, a brightness upper limit of a display of the target display screen is reduced. Since high temperature is one of the reasons for generating the burn-in phenomenon at the display screen, and the installation positions of the vehicle-mounted display screens in a vehicle are different, environmental temperatures during usage will also have certain differences. Thus, based on the temperature data collected by the temperature sensor of each display screen, targeted adjustment is performed on the display brightness upper limit of the display screen.

[0090] In an embodiment, a display mode of the target display screen is obtained. If the display mode is a night mode or a dark mode, a brightness upper limit of a display of the target display screen is reduced. Since a significant grayscale adjacency difference is one of the causes leading to the occurrence of the burn-in phenomenon of the display screen, therefore, after the target display screen enters the night mode or the dark mode, the occurrence of the burn-in situation is effectively avoided by reducing the display brightness upper limit of the target display screen.

[0091] In this embodiment, in order to further avoid the occurrence of the burn-in phenomenon, an automatic adjustment of the display brightness is performed on the display screen that is not being watched. Furthermore, the display brightness of the target display screen is not directly reduced to the minimum display brightness, but gradually reduced, thereby capable of effectively improving the user's use experience. Further, in the process of gradually reducing the display screen brightness, the zero-gaze continuous duration of the target display screen is positively correlated with the brightness reduction rate. That is, when the display brightness of the target display screen starts to be reduced, an overall brightness variation amount is relatively small. Thus, it can effectively avoid a situation where the brightness of the display screen reduces too much in a short time, resulting in a long recovery time waiting when the user intends to use it. On the basis of ensuring the user's perception of use, the occurrence of the burn-in situation of the vehicle-mounted display screen is effectively avoided.
