Description

Technical Field

[0001] The present application relates to computer technology, and in particular to a method, device, equipment and medium for controlling a high color gamut display screen. Background Art

[0002] The power-off sequence of the display refers to the process in which each component is gradually shut down in a specific order and time interval when the display power is turned off. The purpose of this sequence design is to protect the display hardware, prevent data loss, and ensure that the display can work normally when it is started next time.

[0003] At present, the power-off sequence of a display screen is generally to first power off the backlight structure of the display screen, and then power off the LCD screen of the display screen. After the backlight structure is powered off, a residual charge effect will be generated. Specifically, the residual charge effect refers to the residual charge of the LED lamp beads in the backlight structure, which will cause the phosphor to continue to be excited, resulting in residual light on the LCD screen.

[0004] For low color gamut displays, the above process is not obvious, but for high color gamut displays, it will cause obvious residual charge effects, which is not conducive to user experience. Summary of the invention

[0008] In a possible implementation manner, the preset duration is related to a property of the backlight structure.

[0009] In one possible implementation, if the backlight structure is powered off while the LCD screen is controlled to start displaying the target image, the preset duration is the first target duration; the first target duration is the duration required to consume the residual charge generated after the backlight structure is powered off.

[0010] In one possible implementation, if the backlight structure is controlled to power off after the LCD screen is controlled to start displaying the target image, the preset duration is the sum of the first target duration and the second target duration; the first target duration is the duration for consuming the residual charge generated after the backlight structure power-off processing is completed, and the second target duration is the duration between the LCD screen starting to display the target image and the start of controlling the backlight structure to power off.

[0013] In a possible implementation, the grayscale of the target image is zero; and the liquid crystal screen of the control display screen displays the target image, including:

DETAILED DESCRIPTION

[0038] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0039] High color gamut display is a display technology that can present a wider range of colors. It is widely used in fields that require high color accuracy and rich color expression, such as professional image editing, video production, games and high-end consumer electronics.

[0040] It should be made clear that a high color gamut display is a type of display, which also includes an LCD screen and a backlight structure. It is understandable that high color gamut displays are also divided into different types. Figure 1 The schematic diagram of the structure of a high color gamut display screen provided in the embodiment of the present application specifically shows a high color gamut thin film transistor liquid crystal display screen (TFT-LCD display screen). Figure 1 As shown, the high color gamut display screen includes a cover plate, a liquid crystal screen and a backlight structure arranged in sequence from top to bottom. Specifically, the liquid crystal screen includes a TFT glass substrate (not shown in the figure), a liquid crystal layer (not shown in the figure), and a CF glass substrate (not shown in the figure). It can be understood that the liquid crystal screen also includes a polarizer (not shown in the figure) arranged on the outside of the TFT glass and the CF glass substrate, and an alignment layer (not shown in the figure) coated on the inside of the TFT glass and the CF glass substrate for guiding the initial arrangement direction of the liquid crystal molecules. In addition, the liquid crystal screen may also include other components, such as sealing materials, etc., which will not be repeated here.

[0041] It is understandable that, in the process of using the display screen, power-off control of the display screen is often involved. For example, when a sleep request is monitored, the display screen needs to be powered off in response to the sleep request. Specifically, Figure 2 FIG. 1 is a schematic diagram of the power-off timing of a high color gamut display screen in the prior art. Figure 2 As shown, when a power-off demand is detected, the backlight structure is first controlled to power off. After the backlight structure is powered off, the LCD screen is powered off at an interval of xxms to optimize energy consumption, protect components and improve user experience. It should be understood that in the case where the backlight structure does not need to be completely powered off, the power off is considered to be completed when the backlight structure is powered off to a preset value. For example, for a lock screen request, the LCD screen can be powered off when the backlight structure is powered off to 10% of the total power.

[0042] In the above power-off sequence, after the power-off process of the backlight structure is completed, the LED lamp beads in the backlight structure will have residual charge, which will cause the phosphor to continue to be excited, resulting in residual light on the LCD screen. This phenomenon can be called the residual charge effect. For low color gamut displays, this residual charge effect is not obvious, but for high color gamut displays, it will cause an obvious residual charge effect.

[0043] For example, for a high color gamut display screen that uses potassium fluorosilicate (K2SiF6:Mn4+, KSF) phosphor containing tetravalent manganese ions, the time it continues to be excited due to the influence of residual charge may last for 19.4ms. Usually, when the delay time for display screen update or change exceeds 1ms, the human eye can notice this delay. In addition, the red light produced by KFS phosphor has a longer wavelength, which appears more prominent and lasting in visual perception, thus giving users a bad visual experience.

[0044] Therefore, the present application provides a high color gamut display screen control method, device, equipment and medium for solving the above problems. Specifically, the high color gamut display screen control method in the present application is executed by any electronic device. When the electronic device needs to power off the backlight structure, the liquid crystal screen of the display screen is controlled to display a target image for shielding the residual charge effect, and the process is continued until the preset time after the backlight structure is powered off, so that the residual charge effect after the backlight structure is powered off can be visually eliminated, which is conducive to improving the user experience.

[0045] In addition, the method of the present application does not involve improvements to the hardware structure of the display screen, which on the one hand enhances the applicability of the method of the present application, and on the other hand improves the flexibility of display screen control.

[0046] It can be understood that the method of the present application is applicable to any scenario using a high color gamut display screen. For example, Figure 3This is an application scenario diagram of a high color gamut display screen control method provided in an embodiment of the present application, such as Figure 3 As shown, the method of the present application can be used in any vehicle. At present, with the rapid development of the automobile industry, in order to meet the various usage requirements of users, high color gamut display screens have become the only choice for various manufacturers.

[0047] Specifically, Figure 3 As shown, the method of the present application is executed by a vehicle controller, and the vehicle controller is connected to a high color gamut display screen controller. When the vehicle controller receives any target request from a user to power off the backlight structure, the high color gamut display screen controller controls the liquid crystal screen of the high color gamut display screen to display the target image, controls the backlight structure of the high color gamut display screen to power off, and makes the liquid crystal screen display the target image for a preset time after the backlight structure is powered off.

[0048] Through the method of the present application, the high color gamut display screen in the vehicle can visually eliminate the residual charge effect of the display screen after the backlight structure loses power, thereby helping to improve the user experience of the vehicle.

[0049] It can be understood that in addition to being executed by a vehicle controller, the method of the present application can also be executed directly by a high color gamut display screen controller, or by any other electronic device such as a user's mobile phone, which is not limited in this embodiment.

[0050] In conjunction with the accompanying drawings, some implementation methods of the high color gamut display screen control method of the present application are described in detail below. In the case where the embodiments do not conflict with each other, the following embodiments and features in the embodiments can be combined with each other.

[0051] The present application provides a method for controlling a high color gamut display screen. Figure 4 A schematic diagram of a high color gamut display screen control method provided in an embodiment of the present application Figure 1 ,like Figure 4 As shown, a high color gamut display screen control method provided in an embodiment of the present application includes the following contents:

[0052] S401, when a target request is monitored, controlling the liquid crystal screen of the display screen to display a target image, and controlling the backlight structure of the display screen to power off.

[0053] Among them, the target request is used to instruct the backlight structure to power off, the target image is used to block the residual charge effect after the backlight structure is powered off, and the LCD screen continues to display the target image until the preset time after the backlight structure is powered off.

[0054] In this embodiment, the electronic device starts to monitor the target request after powering on, and confirms that the target request has been monitored when it monitors that the user or the display screen itself triggers the need to power off the backlight structure. Specifically, when the user triggers a sleep request, a shutdown request, or a lock screen request, the backlight structure needs to be powered off. Therefore, when the electronic device receives the aforementioned user request, it confirms that the target request has been monitored. When the display screen's own protection mechanism is triggered, it also confirms that the target request has been monitored. For example, in a high temperature environment, the display screen's own protection mechanism is triggered, and at this time, the backlight structure needs to be powered off to effectively protect the display screen.

[0055] It is understandable that the target request can also be used to instruct the LCD screen to be powered off, which is not limited in this embodiment. In addition, in this embodiment, the power-off process is specifically used to instruct the backlight structure or the LCD screen to be discharged to a preset value, which can be zero, and is specifically set according to the type of target request. For example, if it is a lock screen request, the backlight structure does not need to be completely powered off at this time, so the preset value can be 10% of the total power, so that it enters a low power consumption state. It should be understood that when the backlight structure is powered off to 10% of the total power, the aforementioned residual charge effect will also exist after the power-off process is completed.

[0056] In this embodiment, the specific content of the target image is not limited, as long as it can block the residual charge effect after the backlight structure is powered off. It can be understood that images with low grayscale levels (close to black or black) can effectively block the aforementioned residual charge effect. Exemplarily, the grayscale of the target image can be zero, that is, the target image can be a completely black image, and all pixels of the LCD screen are set to the lowest brightness to block the light generated by the backlight structure.

[0057] It is understandable that the preset time length is used to end the residual charge effect after the backlight structure is powered off. In this embodiment, the preset time length can be an empirical value set by the user, based on which the residual charge effect can be visually eliminated.

[0058] As a preferred example, the preset duration is related to the properties of the backlight structure. Specifically, in this embodiment, the electronic device configures the preset duration based on the properties of the backlight structure of the high color gamut display screen. For example, for a high color gamut display screen using KFS phosphor, since it may continue to be excited for 19.4ms due to the influence of residual charge, the preset duration can be set to 19.4ms, or 20ms, as long as the residual charge effect can be visually eliminated.

[0059] Through the above settings, for different high color gamut display screens, the electronic device can flexibly configure the preset time length, which can shorten the time length for displaying the target image as much as possible, so that subsequent steps can be executed in time, which is beneficial to ensuring the response efficiency of the high color gamut display screen.

[0060] In the method provided in this embodiment, when the electronic device monitors the target request, it controls the liquid crystal screen of the display screen to display the target image for shielding the residual charge effect after the backlight structure is powered off, and controls the backlight structure of the display screen to power off. In this process, the liquid crystal screen displays the target image until the preset time after the backlight structure is powered off.

[0061] Through the method of this embodiment, the residual charge effect after the backlight structure is powered off can be effectively shielded by the target image, thereby visually eliminating the residual charge effect to improve the user experience.

[0062] It is understandable that in the above process, the electronic device can simultaneously control the LCD screen to display the target image and control the backlight structure to power off, or can first control the LCD screen to display the target image and then control the backlight structure to power off.

[0063] Correspondingly, if the backlight structure is powered off while the LCD screen is controlled to start displaying the target image, the preset duration is the first target duration; the first target duration is the duration for consuming the residual charge generated after the backlight structure power-off process is completed.

[0064] Specifically, in this embodiment, the duration of the residual charge generated after the backlight structure power-off process is consumed is determined by the properties of the backlight structure. At the same time, the LCD screen is controlled to display the target image and the backlight structure is controlled to power off, so that the backlight structure power-off process can be completed in time, so that subsequent steps, such as the process of powering off the LCD screen, can be executed in time, which is beneficial to ensure the response efficiency of the display screen.

[0065] If the backlight structure is powered off after the LCD screen is controlled to start displaying the target image, the preset duration is the sum of the first target duration and the second target duration; the first target duration is the duration for consuming the residual charge generated after the backlight structure power-off processing is completed, and the second target duration is the duration between the LCD screen starting to display the target image and the start of controlling the backlight structure to power off.

[0066] Specifically, in this embodiment, the electronic device starts timing when the LCD screen is controlled to start displaying the target image, and ends timing when the backlight structure is controlled to power off, thereby obtaining the second target duration. Firstly controlling the LCD screen to display the target image and then controlling the backlight structure to start powering off can further ensure that the user cannot visually perceive the aforementioned residual charge effect.

[0067] The present application also provides a method embodiment, which is used to explain how to control a liquid crystal screen of a display screen to display a target image on one hand, and to provide supplementary explanation for a target request on the other hand. Figure 5 A schematic diagram of a high color gamut display screen control method provided in an embodiment of the present application Figure 2 ,like Figure 5 As shown, the method of this embodiment includes:

[0068] S501, when a target request is monitored, controlling the liquid crystal screen of the display screen to display a target image, and controlling the backlight structure of the display screen to power off.

[0069] Among them, the target request is any one of a lock screen request, a sleep request, and a shutdown request; the grayscale value of the target image is zero, and the LCD screen continues to display the target image for a preset time after the backlight structure is powered off.

[0070] In this embodiment, the electronic device controls the liquid crystal screen to display the target image and controls the backlight structure to power off simultaneously, and the preset duration is specifically the first target duration.

[0071] Specifically, as a design, the electronic device controls the LCD screen to display the target image in the following manner: a full black signal is sent to the display controller of the display screen, so that the display controller adjusts the voltage of all pixels of the LCD screen to a state where the liquid crystal molecules are arranged to block the passage of the pipeline.

[0072] As another design, the electronic device may control the LCD screen to display the target image in the following manner: generate all-black image data; send the all-black image data to the display controller of the display screen, so that the display controller controls the LCD screen to display the all-black image.

[0073] In the above process, the electronic device controls the display controller of the display screen to effectively visually block the residual charge effect caused by the power failure of the backlight structure, which has the advantage of being simple and easy to implement.

[0074] It is understandable that in this embodiment, the method of controlling the LCD screen to display the target image is not limited. For example, in practical applications, it can also be achieved by adjusting the register configuration of the display controller, which is a known technology and will not be described in detail in this embodiment.

[0075] S502, after the backlight structure is powered off, the LCD screen is controlled to enter any one of the following states according to the target request: screen lock state, sleep state, and shutdown state.

[0076] Specifically, if the target request is a lock screen request, the LCD screen is controlled to enter a lock screen state; if the target request is a sleep state, the LCD screen is controlled to enter a sleep state; if the target request is a shutdown state, the LCD screen is controlled to enter a shutdown state.

[0077] In this embodiment, when the target request is a lock screen request, the power-off processing of the backlight structure is incomplete power-off, and the LCD screen is not powered off. The LCD screen can then respond to the user setting to display the corresponding lock screen page.

[0078] On this basis, the electronic device controls the LCD screen to enter the lock screen state, including: generating lock screen image data, sending the lock screen image data to the display controller of the display screen, and causing the display controller to control the LCD screen to display the lock screen image. The lock screen image data is specifically generated according to user needs. For example, when the user needs to display the time and temperature when the high color gamut display screen is locked, the generated lock screen image data includes the current time and temperature.

[0079] In this embodiment, when the target request is a sleep request, the backlight structure is completely powered off or partially powered off, and the LCD screen is completely powered off or partially powered off, so that the high color gamut display screen enters a low power consumption mode. When the target request is a shutdown request, the backlight structure and the LCD screen are completely powered off, so that the high color gamut display screen enters a shutdown state.

[0080] Furthermore, when the power-off processing of the backlight structure or the LCD screen can be a complete power-off processing or an incomplete power-off processing, the electronic device can feedback prompt information when receiving the target request to prompt the user to make a selection, or it can make the selection based on the user's historical usage habits. This is not limited in this embodiment.

[0081] Through the above settings, the electronic device can accurately control the backlight structure and LCD screen according to different target requests. In addition, under different target requests, the power-off processing method of the backlight structure and LCD screen can be configured according to user needs or historical usage habits, which improves the flexibility of high color gamut display control.

[0082] In the method provided in this embodiment, the electronic device controls the backlight structure to power off while controlling the LCD screen to display the target image, so that subsequent control of the LCD screen can be realized in a timely manner, effectively ensuring the response speed of the high color gamut display screen to the target request, which is conducive to further improving the user experience.

[0083] Through the method of this embodiment, it is possible to achieve the effect of effectively eliminating the residual charge effect visually from the software level without involving changes to the hardware or power-off timing. This improves the control flexibility and convenience of the high color gamut display screen on the one hand, and enhances the applicability of the method of this embodiment on the other.

[0084] In addition, for any device that uses a high color gamut display, such as a vehicle, the method of this embodiment can provide a new perspective for the device to solve the residual charge effect of the high color gamut display, that is, not only can the processing be optimized from the screen end, but the problem can also be solved from the perspective of the entire vehicle, that is, the vehicle controller controls the high color gamut display on the vehicle based on the method of this embodiment, so as to achieve the effect of visually eliminating the residual charge effect.

[0085] It should be noted that, for the aforementioned method embodiments, for the sake of simplicity, they are all expressed as a series of action combinations, but those skilled in the art should be aware that the present application is not limited by the described order of actions, because according to the present application, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all optional embodiments, and the actions and modules involved are not necessarily required by the present application.

[0086] It should be further noted that, although the various steps in the flowchart are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence in the order indicated by the arrows. Unless there is a clear description in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders.
