Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and more specifically, to a method, a device and a readable storage medium for eliminating display screen smear in the field of vehicle technology. Background Art

[0002] With the rapid development of display technology, liquid crystal display products have been widely used. For example, liquid crystal display (LCD) has the advantages of low power consumption, small size, and low radiation, and is widely used in screen displays of televisions, computers, and vehicle streaming media rearview mirrors. The core of the LCD screen display is "the change in the arrangement direction of liquid crystal molecules", that is, the activity of liquid crystal molecules. However, liquid crystal materials are very sensitive to the temperature of the environment. The lower the temperature, the slower the liquid crystal molecules flip, which means that the response time of the LCD screen will become longer, that is, there will be a smear phenomenon, affecting the display effect.

[0003] Therefore, how to reduce the response time of the LCD screen in a low temperature environment is an urgent problem that needs to be solved. Summary of the invention

[0004] The present application provides a method, device and readable storage medium for eliminating display screen ghosting. The method can reduce the response time of an LCD screen in a low temperature environment, thereby shortening the duration of ghosting on the LCD screen and improving the display effect of the LCD screen.

[0005] In a first aspect, a method for eliminating display screen ghosting is provided, and the method is applied to a streaming media rearview mirror of a vehicle, and the method comprises: when the streaming media rearview mirror starts a streaming media display mode, in response to the streaming media rearview mirror being in a preset temperature range, obtaining a first initial brightness of the screen of the streaming media rearview mirror and an initial transmittance of a dimming glass covered on the screen, the streaming media display mode being a mode in which the streaming media rearview mirror can display an image behind the vehicle; determining a first transmittance of the dimming glass according to a target brightness, a first initial brightness, and an initial transmittance of the streaming media rearview mirror, the target brightness being greater than the first initial brightness and less than or equal to a maximum brightness that the screen of the streaming media rearview mirror can reach, and the first transmittance being less than the initial transmittance of the dimming glass; and adjusting the brightness of the screen to the target brightness and adjusting the transmittance of the dimming glass to the first transmittance.

[0006] In the above technical solution, when the streaming media rearview mirror is in a preset temperature range and the streaming media display mode is started, the first initial brightness of the screen of the streaming media rearview mirror and the initial transmittance of the dimming glass covered on the screen can be obtained, and the first transmittance of the dimming glass can be determined according to the target brightness, the first initial brightness and the initial transmittance of the streaming media rearview mirror, so that the brightness of the screen of the streaming media rearview mirror is finally adjusted to the target brightness and the transmittance of the dimming glass is adjusted to the first transmittance. Since the target brightness is greater than the first initial brightness, after the brightness of the screen of the streaming media rearview mirror is increased to the target brightness, the power consumption of the screen of the streaming media rearview mirror will increase due to the increase in brightness, that is, the temperature of the screen of the streaming media rearview mirror will increase, so that the speed of flipping of the liquid crystal molecules of the screen of the streaming media rearview mirror can be accelerated, and the response time of the screen of the streaming media rearview mirror can be reduced, that is, the duration of the screen of the streaming media rearview mirror with ghosting will be shortened, and the display effect of the screen of the streaming media rearview mirror will be improved. In addition, since the first transmittance is lower than the initial transmittance, after the transmittance of the dimming glass is reduced to the first transmittance, the user will not obviously perceive the change in screen brightness due to the reduction in transmittance, thereby ensuring that the duration of ghosting on the screen of the streaming media rearview mirror is shortened while avoiding the user's discomfort caused by the increase in screen brightness.

[0007] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, when the streaming media rearview mirror starts the streaming media display mode, in response to the streaming media rearview mirror being in a preset temperature range, before obtaining the first initial brightness of the screen of the streaming media rearview mirror and the initial transmittance of the dimming glass covering the screen, the method also includes: obtaining a first temperature of the streaming media rearview mirror, the first temperature being the temperature when the streaming media rearview mirror starts the streaming media display mode; when the first temperature is less than a temperature threshold, determining that the streaming media rearview mirror is in the preset temperature range.

[0008] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the first transmittance of the dimming glass is determined according to the target brightness, the first initial brightness and the initial transmittance of the streaming media rearview mirror, including: determining the brightness ratio according to the first initial brightness and the target brightness; determining the first transmittance according to the brightness ratio and the initial transmittance.

[0009] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the brightness of the screen is adjusted to the target brightness and the transmittance of the dimming glass is adjusted to the first transmittance, including: determining the brightness adjustment value of the screen of the streaming media rearview mirror according to the target brightness and the first initial brightness; determining the transmittance adjustment value of the dimming glass according to the first transmittance and the initial transmittance; adjusting the brightness of the screen to the target brightness according to the brightness adjustment value, and adjusting the transmittance of the dimming glass to the first transmittance according to the transmittance adjustment value.

[0010] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the transmittance adjustment value of the dimming glass is determined according to the first transmittance and the initial transmittance, including: judging whether the first transmittance is less than the minimum transmittance of the dimming glass; when the first transmittance is less than the minimum transmittance, determining the transmittance adjustment value according to the minimum transmittance and the initial transmittance, and taking the minimum transmittance as the first transmittance; when the first transmittance is greater than the minimum transmittance, determining the transmittance adjustment value according to the first transmittance and the initial transmittance.

[0011] It should be noted that the light transmittance of the dimming glass can generally only be adjusted within the calibrated light transmittance range. In other words, the dimming glass has a minimum light transmittance and a maximum light transmittance. Considering that the determined first light transmittance may be less than the minimum light transmittance of the dimming glass, that is, in this case, the light transmittance of the dimming glass cannot be adjusted to the first light transmittance, and the light transmittance of the dimming glass can only be reduced to the minimum light transmittance at the lowest. Therefore, after determining the first light transmittance, that is, according to the first light transmittance and the initial light transmittance, the light transmittance of the dimming glass is determined. When adjusting the light transmittance value, the relationship between the first transmittance and the minimum transmittance of the dimming glass can be determined first, so that when the first transmittance is less than the minimum transmittance, the transmittance adjustment value is determined according to the minimum transmittance and the initial transmittance, and the minimum transmittance is used as the first transmittance; when the first transmittance is greater than the minimum transmittance, the transmittance adjustment value is determined according to the first transmittance and the initial transmittance, thereby ensuring the accuracy of the determined transmittance adjustment value, that is, ensuring that the transmittance of the dimming glass can be adjusted to the first transmittance subsequently.

[0012] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the method also includes: when the first transmittance is less than the minimum transmittance, displaying a prompt message, the prompt message is used to indicate that the streaming media rearview mirror is currently in a heating state.

[0013] In the above technical method, since the transmittance of the dimming glass cannot be reduced to the first transmittance when the first transmittance is less than the minimum transmittance of the dimming glass, the transmittance of the dimming glass can only be reduced to the minimum transmittance at the lowest. That is, when the first transmittance is less than the minimum transmittance, it cannot be guaranteed that the brightness of the screen of the streaming media rearview mirror will not change significantly while shortening the duration of the smear on the screen of the streaming media rearview mirror, that is, the user will perceive that the screen brightness has increased significantly. Therefore, in this case, information indicating that the streaming media rearview mirror is currently in a heating state can be displayed to enable the user to better understand the reason for the obvious increase in screen brightness, thereby improving the car experience.

[0014] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, after the brightness of the screen is adjusted to the target brightness and the transmittance of the dimming glass is adjusted to the first transmittance, the method also includes: obtaining a second temperature of the streaming media rearview mirror, the second temperature being the temperature after the brightness of the screen is adjusted to the target brightness; when the second temperature is equal to or greater than the temperature threshold, adjusting the screen to the first initial brightness and adjusting the transmittance of the dimming glass to the initial transmittance.

[0015] In the above technical solution, after the brightness of the screen is adjusted to the target brightness and the transmittance of the dimming glass is adjusted to the first transmittance, the temperature (second temperature) of the streaming media rearview mirror after the brightness of the screen is adjusted to the target brightness can be obtained, and the second temperature can be compared with the temperature threshold, so that when the second temperature is equal to or greater than the temperature threshold, that is, when the streaming media rearview mirror is not within the preset temperature range and can display the image normally, the screen of the streaming media rearview mirror is restored to the brightness before adjustment, and the transmittance of the dimming glass is restored to the transmittance before adjustment, that is, the screen is adjusted to the first initial brightness and the transmittance of the dimming glass is adjusted to the initial transmittance, so as to reduce the power consumption of the screen of the streaming media rearview mirror.

[0016] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, after adjusting the brightness of the screen to the target brightness and adjusting the transmittance of the dimming glass to the first transmittance, the method also includes: obtaining a second temperature of the streaming media rearview mirror, the second temperature being the temperature after the brightness of the screen is adjusted to the target brightness; when the second temperature is equal to or greater than the temperature threshold, obtaining the ambient light intensity of the streaming media rearview mirror; determining a second initial brightness of the screen and a second transmittance of the dimming glass corresponding to the ambient light intensity according to a preset relationship correspondence table; adjusting the screen to the second initial brightness and adjusting the transmittance of the dimming glass to the second transmittance.

[0017] It should be noted that, when the second temperature is equal to or greater than the temperature threshold, that is, when the streaming media rearview mirror is not in the preset temperature range and can display images normally, considering that the ambient light intensity of the streaming media rearview mirror may change compared to the ambient light intensity when the streaming media rearview mirror is in the preset temperature range, in order to ensure that the screen brightness of the media rearview mirror can adapt to the ambient light intensity of the streaming media rearview mirror, in other words, to avoid the situation where the screen brightness of the streaming media rearview mirror is too high or too low to affect the user experience, in a possible implementation, the ambient light intensity of the streaming media rearview mirror can be obtained when the second temperature is equal to or greater than the temperature threshold; according to the preset relationship correspondence table, the second initial brightness of the screen and the second transmittance of the dimming glass corresponding to the ambient light intensity are determined, and the screen is adjusted to the second initial brightness corresponding to the ambient light intensity, and the transmittance of the dimming glass is adjusted to the second transmittance corresponding to the ambient light intensity, so as to ensure that the screen brightness of the media rearview mirror can adapt to the ambient light intensity of the streaming media rearview mirror, and avoid the situation where the screen brightness of the streaming media rearview mirror is too high or too low to affect the user experience.

[0018] In a second aspect, a device for eliminating display screen ghosting is provided, which is applied to a streaming media rearview mirror of a vehicle, and the device includes: a response module, which is used to obtain a first initial brightness of the screen of the streaming media rearview mirror and an initial transmittance of a dimming glass covered on the screen in response to the streaming media rearview mirror being in a preset temperature range when the streaming media rearview mirror starts a streaming media display mode, and the streaming media display mode is a mode in which the streaming media rearview mirror can display an image behind the vehicle; a determination module, which is used to determine a first transmittance of the dimming glass according to a target brightness, a first initial brightness and an initial transmittance of the streaming media rearview mirror, the target brightness is greater than the first initial brightness and less than or equal to the maximum brightness that the screen of the streaming media rearview mirror can reach, and the first transmittance is less than the initial transmittance of the dimming glass; an adjustment module, which is used to adjust the brightness of the screen to the target brightness and adjust the transmittance of the dimming glass to the first transmittance.

[0019] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the device also includes an acquisition module for acquiring a first temperature of the streaming media rearview mirror, where the first temperature is the temperature when the streaming media rearview mirror starts the streaming media display mode; the determination module is also used to determine that the streaming media rearview mirror is in a preset temperature range when the first temperature is less than a temperature threshold.

[0020] In combination with the second aspect and the above implementations, in some possible implementations, the determination module is specifically used to determine the brightness ratio according to the first initial brightness and the target brightness; and determine the first transmittance according to the brightness ratio and the initial transmittance.

[0021] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the determination module is specifically used to determine the brightness adjustment value of the screen of the streaming media rearview mirror according to the target brightness and the first initial brightness; determine the transmittance adjustment value of the dimming glass according to the first transmittance and the initial transmittance; the adjustment module is specifically used to adjust the brightness of the screen to the target brightness according to the brightness adjustment value, and adjust the transmittance of the dimming glass to the first transmittance according to the transmittance adjustment value.

[0022] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the determination module is specifically used to determine whether the first transmittance is less than the minimum transmittance of the dimming glass; when the first transmittance is less than the minimum transmittance, the transmittance adjustment value is determined according to the minimum transmittance and the initial transmittance, and the minimum transmittance is used as the first transmittance; when the first transmittance is greater than the minimum transmittance, the transmittance adjustment value is determined according to the first transmittance and the initial transmittance.

[0023] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the device also includes a display module for displaying a prompt message when the first transmittance is less than the minimum transmittance, and the prompt message is used to indicate that the streaming media rearview mirror is currently in a heating state.

[0024] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the acquisition module is also used to obtain a second temperature of the streaming media rearview mirror, where the second temperature is the temperature after the brightness of the screen is adjusted to the target brightness; the adjustment module is also used to adjust the screen to the first initial brightness and adjust the transmittance of the dimming glass to the initial transmittance when the second temperature is equal to or greater than the temperature threshold.

[0025] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the acquisition module is also used to obtain a second temperature of the streaming media rearview mirror, where the second temperature is the temperature after the brightness of the screen is adjusted to the target brightness; when the second temperature is equal to or greater than the temperature threshold, the ambient light intensity of the streaming media rearview mirror is obtained; the determination module is also used to determine the second initial brightness of the screen and the second transmittance of the dimming glass corresponding to the ambient light intensity according to a preset relationship correspondence table; the adjustment module is also used to adjust the screen to the second initial brightness and adjust the transmittance of the dimming glass to the second transmittance.

[0033] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0034] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0035] Figure 1 It is a schematic diagram of the side view structure of a streaming media rearview mirror of a vehicle provided in an embodiment of the present application.

[0036] For example, Figure 1 As shown, the streaming media rearview mirror 100 includes: a display screen module 101 (which can be understood as the screen of the streaming media rearview mirror), a dimming glass 102 (which can also be called electrically controlled liquid crystal glass, electrically controlled dimming glass) and a cover glass 103.

[0037] When the streaming media rearview mirror 100 is Figure 1 When placed horizontally as shown, the dimming glass 102 covers the top of the display screen module 101 and is used to adjust the transmittance of the display screen module 101. It should be noted that the dimming glass 102 is a glass whose transparency can be changed by electrical control (voltage). Specifically, the transmittance of the dimming glass 102 is usually directly related to the voltage applied thereto, that is, when there is no voltage, the dimming glass 102 is in an opaque state, and the transmittance is very low and close to zero. As the voltage continues to increase, the transmittance of the dimming glass 102 will increase accordingly.

[0038] The cover glass 103 covers the dimming glass 102 to protect the dimming glass 102 and the display screen module 101 from being damaged.

[0039] Optionally, the material of the cover glass 103 may be soda lime, aluminosilicate, soda lime silicon or other transparent organic materials, which is not limited in the embodiment of the present application.

[0040] In a possible implementation, Figure 2 As shown, the display screen module 101 includes a backlight 1011 and a liquid crystal display screen 1012. The backlight 1011 is disposed below the liquid crystal display screen 1012 to illuminate the liquid crystal display screen 1012, that is, to provide a light source for the liquid crystal display screen 1012 so that the liquid crystal display screen can display a clear image.

[0041] Optionally, the backlight 1011 can be any one of a light emitting diode (LED), an organic light emitting diode (OLED), or a micro light emitting diode (Micro LED), etc., and the embodiments of the present application are not limited to this.

[0042] It should be noted that the core of LCD display is "the change of arrangement direction of liquid crystal molecules", that is, the activity of liquid crystal molecules. However, liquid crystal materials are very sensitive to the temperature of the environment. The lower the temperature, the slower the liquid crystal molecules flip, which means that the response time of the LCD will be longer, that is, there will be a phenomenon of smearing, which affects the display effect.

[0043] Therefore, how to reduce the response time of the LCD screen in a low temperature environment is an urgent problem to be solved.

[0044] Based on the above problems, the present application provides a method for eliminating display screen ghosting, which can reduce the response time of the liquid crystal display in a low temperature environment, thereby shortening the duration of the liquid crystal display ghosting and improving the display effect of the liquid crystal display.

[0045] It should be understood that the method for eliminating display screen ghosting provided in the embodiment of the present application can be applied to vehicles equipped with streaming media rearview mirrors, and can be specifically applied to, for example Figure 1 The streaming media rearview mirror 100 is shown.

[0046] Below through Figure 3 The method of the embodiment of the present application is described in detail.

[0047] Figure 3 is a schematic flow chart of a method for eliminating display screen smear provided by an embodiment of the present application, the method is applied to Figure 1 The streaming media rearview mirror 100 is shown.

[0048] For example, Figure 3 As shown, the method 300 includes the following steps 301 to 304.

[0049] Step 301, when the streaming media rearview mirror starts the streaming media display mode, determine whether the streaming media rearview mirror is within a preset temperature range.

[0050] Streaming media rearview mirrors usually have two working modes: traditional physical mirror mode and streaming media display mode.

[0051] Optionally, the user can manually switch between the two modes through a physical button configured on the streaming media rearview mirror, or through a virtual button configured on the central control screen of the vehicle, which is not limited in the present embodiment. In addition, the vehicle can also automatically switch between the two modes according to the vehicle state (for example, reversing, high-speed driving, etc.).

[0052] It should be noted that in the physical mirror mode, the function of the streaming media rearview mirror is the same as that of the traditional vehicle's interior rearview mirror. It provides the driver with a view of the rear of the vehicle through mirror reflection, but due to the limitations of the vehicle body structure and rear seat passengers, the display field of view is small. In the streaming media display mode, the streaming media rearview mirror captures the image of the rear of the vehicle in real time through a camera installed at the rear of the vehicle, and displays the image on the LCD screen, providing the user with a wider view of the rear of the vehicle.

[0053] It should be understood that the core idea of ​​the method provided by the present application is to increase the brightness of the screen of the streaming media rearview mirror and reduce the light transmittance of the dimming glass when the streaming media rearview mirror is in a preset temperature range and the streaming media display mode is activated, so as to ensure that when the screen brightness of the streaming media rearview mirror increases (it can also be understood that the screen temperature of the streaming media rearview mirror is increasing), the user does not obviously perceive the change in screen brightness, that is, to ensure that while shortening the duration of the screen smear of the streaming media rearview mirror, the user is prevented from feeling uncomfortable due to the increase in screen brightness. Therefore, when implementing the method provided by the embodiment of the present application, it is necessary to determine whether the streaming media rearview mirror is in a preset temperature range when the streaming media rearview mirror starts the streaming media display mode.

[0054] It can be understood that the preset temperature range is a temperature range that can cause the streaming media rearview mirror to have a ghosting phenomenon when the streaming media display mode is started.

[0055] In a possible implementation, the temperature when the streaming media rearview mirror starts the streaming media display mode, that is, the first temperature, can be obtained, and based on the relationship between the first temperature and the temperature threshold, it is determined whether the streaming media rearview mirror is in a preset temperature range.

[0056] Among them, the temperature threshold is pre-set by the developer based on experimental data. For example, the temperature threshold may be -5°C, -10°C or -15°C, etc., and this embodiment of the present application does not limit this.

[0057] The first temperature of the streaming media rearview mirror can be measured by an internal temperature sensor or an external temperature sensor configured on the streaming media rearview mirror, which is not limited in the embodiment of the present application.

[0058] Specifically, after obtaining the first temperature of the streaming media rearview mirror, the first temperature can be compared with a temperature threshold, so that when the first temperature is less than the temperature threshold, it is determined that the streaming media rearview mirror is within a preset temperature range.

[0059] Exemplarily, when the first temperature of the streaming media rearview mirror is -15°C and the temperature threshold is -10°C, the first temperature of the streaming media rearview mirror (-15°C) can be compared with the temperature threshold (-10°C). Since the first temperature of the streaming media rearview mirror (-15°C) is less than the temperature threshold (-10°C), it can be determined that the streaming media rearview mirror is within the preset temperature range.

[0060] Step 302, when the streaming media rearview mirror is in a preset temperature range, obtain a first initial brightness of the screen of the streaming media rearview mirror and an initial transmittance of the dimming glass covering the screen.

[0061] It should be understood that the screen of the streaming media rearview mirror is Figure 1 The display screen module 101 shown in the figure has a dimming glass covering the screen. Figure 1 The switchable glass 103 is shown.

[0062] Among them, the first initial brightness is the screen brightness when the streaming media rearview mirror is in a preset temperature range; the initial transmittance is the transmittance of the dimming glass when the streaming media rearview mirror is in a preset temperature range.

[0063] In a possible implementation, the first initial brightness and initial transmittance can be obtained in the following manner: obtaining the ambient light intensity of the streaming media rearview mirror; and determining the first initial brightness and initial transmittance corresponding to the ambient light intensity according to a preset relationship correspondence table.

[0064] Among them, the ambient light intensity of the streaming media rearview mirror can be measured by an ambient light sensor.

[0065] Specifically, the developer can store a preset relationship table of ambient light intensity, initial brightness, and initial transmittance of the streaming media rearview mirror in the vehicle. In the relationship table, the greater the ambient light intensity, the greater the initial brightness of the screen and the initial transmittance of the dimming glass. After obtaining the ambient light intensity of the streaming media rearview mirror, the relationship table can be searched based on the ambient light intensity to obtain the initial brightness of the screen and the initial transmittance of the dimming glass when the streaming media rearview mirror is in a preset temperature range.

[0066] For example, the relationship between ambient light intensity, initial brightness, and initial light transmittance may be shown in Table 1 below:

[0067] Table 1

[0068] Ambient light intensity Initial Brightness Initial light transmittance 50lux <![CDATA[300cd / m 2 ]]> 50％ …… …… …… 500lux <![CDATA[600cd / m 2 ]]> 60％ …… …… …… 1000lux <![CDATA[1500cd / m 2 ]]> 75％ …… …… ……

[0069] From Table 1 above, we can see that the ambient light intensity (50 lux) of the streaming media rearview mirror corresponds to the initial brightness of the screen (300 cd / m 2 ), the initial light transmittance of the dimming glass (50%); the ambient light intensity of the streaming media rearview mirror (500 lux) corresponds to the initial brightness of the screen (600 cd / m 2 ), the initial light transmittance of the dimming glass (60%); the ambient light intensity of the streaming media rearview mirror (1000 lux) corresponding to the initial brightness of the screen (1500 cd / m 2 ), the initial light transmittance of the dimming glass (75%), etc.

[0070] It should be noted that, since the transmittance of the dimming glass can generally only be adjusted within the calibrated transmittance range, in other words, the dimming glass has a minimum transmittance and a maximum transmittance. Therefore, the initial transmittance of the dimming glass corresponding to the ambient light intensity in the above Table 1 will never be greater than the maximum transmittance of the dimming glass, and will never be less than the minimum transmittance of the dimming glass.

[0071] Step 303, determining the first transmittance of the dimming glass according to the target brightness, the first initial brightness and the initial transmittance of the streaming media rearview mirror, the target brightness is greater than the first initial brightness and less than or equal to the maximum brightness that the screen of the streaming media rearview mirror can reach, and the first transmittance is less than the initial transmittance of the dimming glass.

[0072] The target brightness is greater than the first initial brightness, so that after the screen brightness is adjusted to the target brightness, the power consumption of the screen of the streaming media rearview mirror can be increased, so that the flipping speed of the liquid crystal molecules of the screen of the streaming media rearview mirror can be accelerated as soon as possible, and the duration of the screen of the streaming media rearview mirror to appear smear can be shortened. It can be understood that the maximum brightness that the screen of the streaming media rearview mirror can reach is pre-stored in the internal memory of the vehicle.

[0073] In a possible implementation, the developer may store a preset first initial brightness-target brightness relationship correspondence table in the vehicle, in which the larger the first initial brightness, the larger the corresponding target brightness. It is understandable that the maximum target brightness will not exceed the maximum brightness that the screen of the streaming media rearview mirror can reach. Specifically, after obtaining the first initial brightness of the screen of the streaming media rearview mirror, the relationship correspondence table may be searched based on the first initial brightness to obtain the target brightness of the streaming media rearview mirror.

[0074] Exemplarily, the first initial brightness-target brightness relationship correspondence table may be shown in Table 2 below:

[0076] First initial brightness Target brightness <![CDATA[300cd / m 2 ]]> <![CDATA[1000cd / m 2 ]]> …… …… <![CDATA[600cd / m 2 ]]> <![CDATA[1300cd / m 2 ]]> …… …… <![CDATA[900cd / m 2 ]]> <![CDATA[1600cd / m 2 ]]> …… …… <![CDATA[1800cd / m 2 ]]> <![CDATA[2400cd / m 2 ]]> …… …… <![CDATA[2100cd / m 2 ]]> <![CDATA[2400cd / m 2 ]]>

[0077] From Table 2 above, it can be seen that the first initial brightness (300 cd / m 2 ) corresponds to the target brightness (1000cd / m 2 ); The first initial brightness of the streaming media rearview mirror (600cd / m 2 ) corresponds to the target brightness (1300cd / m 2 ); The first initial brightness of the streaming media rearview mirror (900cd / m 2 ) corresponds to the target brightness (1600cd / m 2 ); The first initial brightness of the streaming media rearview mirror (1800cd / m2 ) corresponds to the target brightness (2400cd / m 2 ); The first initial brightness of the streaming media rearview mirror (2100cd / m 2 ) corresponds to the target brightness (2400cd / m 2 ), etc., and from the above Table 2, it can be seen that the maximum brightness that the screen of the streaming media rearview mirror can reach is 2400cd / m 2 .

[0078] In another possible implementation, the target brightness can always be the maximum brightness that the screen of the streaming media rearview mirror can reach, so that the power consumption of the screen of the streaming media rearview mirror can be maximized, thereby shortening the duration of ghosting on the screen of the streaming media rearview mirror to the greatest extent.

[0079] In a possible implementation, after obtaining the target brightness, the first initial brightness and the initial transmittance of the streaming media rearview mirror, the transmittance that is less than the initial transmittance of the dimming glass, i.e., the first transmittance, can be obtained based on the target brightness, the first initial brightness and the initial transmittance.

[0080] The following describes in detail how to obtain the first light transmittance according to the target brightness, the first initial brightness and the initial light transmittance.

[0081] In a possible implementation manner, the brightness ratio may be determined first according to the first initial brightness and the target brightness, and then the first transmittance may be determined according to the brightness ratio and the initial transmittance.

[0082] It can be understood that since the target brightness is greater than the first initial brightness, the ratio of the first initial brightness to the target brightness is less than 1, that is, the brightness ratio is less than 1, so the first transmittance obtained by multiplying the brightness ratio by the initial transmittance is less than the initial transmittance.

[0083] For example, when the first initial brightness is 300 cd / m 2 , target brightness is 2400cd / m 2 When the initial light transmittance is 50%, the first initial brightness (300 cd / m 2 ) and target brightness (2400cd / m 2 ) ratio (brightness ratio), that is, brightness ratio = 300cd / m 2 / 2400cd / m 2 =0.125, and then multiply the brightness ratio (0.125) by the initial transmittance (50%) to obtain the first transmittance, that is, the first transmittance = 0.125 × 50% ≈ 6%, and the first transmittance (6%) is less than the initial transmittance (50%).

[0084] For another example, when the first initial brightness is 1500 cd / m 2 , target brightness is 2400cd / m 2 When the initial light transmittance is 75%, the first initial brightness (1500 cd / m 2 ) and target brightness (2400cd / m 2 ) ratio (brightness ratio), that is, brightness ratio = 1500cd / m 2 / 2400cd / m 2 =0.625, and then the brightness ratio (0.625) is multiplied by the initial transmittance (75%) to obtain the first transmittance, that is, the first transmittance = 0.625 × 75% ≈ 47%, and the first transmittance (47%) is less than the initial transmittance (75%).

[0085] It can be seen from the above embodiments that the transmittance of the dimming glass can generally only be adjusted within the calibrated transmittance range, that is, the dimming glass has a minimum transmittance and a maximum transmittance. That is, in the embodiments of the present application, it is considered that the transmittance (first transmittance) obtained according to the target brightness, the first initial brightness and the initial transmittance may be less than the minimum transmittance of the dimming glass. In this case, the initial transmittance of the dimming glass cannot be reduced to the first transmittance, and the transmittance of the dimming glass can only be reduced to the minimum transmittance. Therefore, after determining the first transmittance according to the target brightness, the first initial brightness and the initial transmittance, that is, before adjusting the transmittance of the dimming glass to the first transmittance, the magnitude relationship between the determined first transmittance and the minimum transmittance of the dimming glass can be determined first, so that when the first transmittance is less than the minimum transmittance, the minimum transmittance is used as the final first transmittance; when the first transmittance is greater than the minimum transmittance, the first transmittance is used as the final first transmittance, so as to ensure that the initial transmittance of the dimming glass can be adjusted to the first transmittance. It can be understood that the minimum transmittance and the maximum transmittance of the dimming glass are pre-stored in the internal memory of the vehicle.

[0086] Exemplarily, when the minimum transmittance of the dimming glass is 10%, and the first transmittance is 6% according to the target brightness, the first initial brightness and the initial transmittance, since the first transmittance (6%) at this time is less than the minimum transmittance (10%) of the dimming glass, in this case it is necessary to use the minimum transmittance (10%) of the dimming glass as the first transmittance, so as to ensure that the initial transmittance of the dimming glass can be adjusted to the first transmittance.

[0087] Step 304, adjusting the brightness of the screen to the target brightness and adjusting the transmittance of the switchable glass to the first transmittance.

[0088] For example, when the first initial brightness is 1500 cd / m2 When the initial transmittance is 75%, the target brightness is 2400cd / m 2 When the first light transmittance is 47%, the screen brightness of the streaming media rearview mirror can be increased from the first initial brightness (1500cd / m 2 ) to the target brightness (2400cd / m 2 ), and reduce the light transmittance of the switchable glass from the initial light transmittance (75%) to the first light transmittance (47%).

[0089] In summary, the method for eliminating display screen smear provided by the embodiment of the present application can obtain the first initial brightness of the screen of the streaming media rearview mirror and the initial transmittance of the dimming glass covered on the screen when the streaming media rearview mirror is in a preset temperature range and the streaming media display mode is started, and determine the first transmittance of the dimming glass according to the target brightness, the first initial brightness and the initial transmittance of the streaming media rearview mirror, so that the brightness of the screen of the streaming media rearview mirror is finally adjusted to the target brightness and the transmittance of the dimming glass is adjusted to the first transmittance. Since the target brightness is greater than the first initial brightness, after the brightness of the screen of the streaming media rearview mirror is increased to the target brightness, the power consumption of the screen of the streaming media rearview mirror will increase due to the increase in brightness, that is, the screen temperature of the streaming media rearview mirror will increase, thereby accelerating the flipping speed of the liquid crystal molecules of the screen of the streaming media rearview mirror, reducing the response time of the screen of the streaming media rearview mirror, that is, shortening the duration of the screen of the streaming media rearview mirror when smear appears, and improving the display effect of the screen of the streaming media rearview mirror. In addition, since the first transmittance is lower than the initial transmittance, after the transmittance of the dimming glass is reduced to the first transmittance, the user will not obviously perceive the change in screen brightness due to the reduction in transmittance, thereby ensuring that the duration of ghosting on the screen of the streaming media rearview mirror is shortened while avoiding the user's discomfort caused by the increase in screen brightness.

[0090] In a possible implementation manner, in step 304, adjusting the brightness of the screen to the target brightness and adjusting the transmittance of the switchable glass to the first transmittance may specifically include the following steps:

[0091] Step 1: Determine a brightness adjustment value of the screen of the streaming media rearview mirror according to the target brightness and the first initial brightness.

[0092] Specifically, after obtaining the first initial brightness and the target brightness, the first initial brightness may be subtracted from the target brightness to obtain a brightness adjustment value of the screen of the streaming media rearview mirror.

[0093] For example, when the target brightness is 2400 cd / m 2 , the first initial brightness is 1500cd / m 2 When the target brightness (2400cd / m2 ) minus the first initial brightness (1500cd / m 2 ), i.e. 2400cd / m 2 -1500cd / m 2 =900cd / m 2 , and the difference (900cd / m 2 ) is used as the brightness adjustment value of the screen of the streaming media rearview mirror.

[0094] A negative brightness adjustment value indicates a decrease in the screen brightness; a positive brightness adjustment value indicates an increase in the screen brightness.

[0095] Step 2: Determine a transmittance adjustment value of the switchable glass according to the first transmittance and the initial transmittance.

[0096] Specifically, after obtaining the first light transmittance and the initial light transmittance, the initial light transmittance may be subtracted from the first light transmittance to obtain a light transmittance adjustment value of the switchable glass.

[0097] For example, when the first light transmittance is 47% and the initial light transmittance is 75%, the initial light transmittance (75%) can be subtracted from the first light transmittance (47%), that is, 47%-75%=-28%, and the difference (-28%) is used as the light transmittance adjustment value of the dimming glass.

[0098] Among them, a positive value of the transmittance adjustment value indicates that the transmittance of the dimming glass is reduced; a positive value of the transmittance adjustment value of the dimming glass indicates that the transmittance of the dimming glass is increased.

[0099] It can be understood that, from the above embodiments, when the transmittance (first transmittance) obtained according to the target brightness, the first initial brightness and the initial transmittance is less than the minimum transmittance of the dimming glass, the minimum transmittance will be used as the final first transmittance. Therefore, when the minimum transmittance is used as the final first transmittance, the transmittance adjustment value of the dimming glass is determined according to the first transmittance and the initial transmittance, which can be understood as determining the transmittance adjustment value of the dimming glass according to the minimum transmittance and the initial transmittance of the dimming glass.

[0100] Step 3: Adjust the brightness of the screen to the target brightness according to the brightness adjustment value, and adjust the transmittance of the dimming glass to the first transmittance according to the transmittance adjustment value.

[0101] Specifically, after determining the brightness adjustment value of the streaming media rearview mirror's screen and the transmittance adjustment value of the dimming glass, the vehicle's whole vehicle controller will send the brightness adjustment value and the transmittance adjustment value to the streaming media rearview mirror controller, so that after receiving the brightness adjustment value and the transmittance adjustment value, the streaming media rearview mirror controller will adjust the brightness of the streaming media rearview mirror's screen to the target brightness and adjust the transmittance of the dimming glass of the streaming media rearview mirror to the first transmittance.

[0102] For example, when the brightness adjustment value is 900 cd / m 2 , the transmittance adjustment value is -28%, and the target brightness of the screen is 2400cd / m 2 , the first initial brightness of the screen is 1500cd / m 2 When the initial light transmittance of the dimming glass is 75% and the first light transmittance of the dimming glass is 47%, the vehicle controller will adjust the brightness to (900cd / m 2 ) and the transmittance adjustment value (-28%) are sent to the streaming media rearview mirror controller. The streaming media rearview mirror controller receives the brightness adjustment value (900cd / m 2 ) and the transmittance adjustment value (-28%), the brightness adjustment value (900cd / m 2 ) Change the screen brightness of the streaming media rearview mirror from the first initial brightness (1500cd / m 2 ) to the target brightness (2400cd / m 2 ), and according to the transmittance adjustment value (-28%), the transmittance of the switchable glass is reduced from the initial transmittance (75%) to the first transmittance (47%).

[0103] It should be noted that, as can be seen from the above embodiments, the transmittance (first transmittance) obtained according to the target brightness, the first initial brightness and the initial transmittance may be less than the minimum transmittance of the dimming glass. In this case, the transmittance of the dimming glass cannot be reduced to the first transmittance, and the transmittance of the dimming glass can only be reduced to the minimum transmittance at the lowest. And as can be seen from the above embodiments, in order to ensure that the initial transmittance of the dimming glass can be adjusted to the first transmittance, in this case, the minimum transmittance is used as the final first transmittance. That is, in this case, it cannot be guaranteed that while shortening the duration of the screen of the streaming media rearview mirror, the user will not obviously perceive the change in screen brightness, which will cause the user to feel uncomfortable. Therefore, in this case, information (prompt information) can be displayed to indicate that the streaming media rearview mirror is currently in a heating state, so that through the prompt information, the user can better understand the reason for the obvious increase in screen brightness, thereby improving the car experience.

[0104] Exemplarily, the prompt message may be "The streaming media rearview mirror is currently in a heating state. In order to shorten the duration of screen ghosting, the screen brightness will be reduced later", or "In order to shorten the duration of screen ghosting, the streaming media rearview mirror is currently in a heating state. The screen brightness will be reduced later", etc. The embodiments of the present application are not limited to this.

[0105] Optionally, the prompt information can be displayed on the central control screen of the vehicle, or on a streaming media rearview mirror, which is not limited in the embodiments of the present application.

[0106] In a possible implementation, after the brightness of the screen is adjusted to the target brightness and the transmittance of the dimming glass is adjusted to the first transmittance, the temperature of the streaming media rearview mirror after the brightness of the screen is adjusted to the target brightness, that is, the second temperature, can be obtained, and the second temperature can be compared with the temperature threshold, so that when the second temperature is equal to or greater than the temperature threshold, that is, when the streaming media rearview mirror is not within the preset temperature range and can display the image normally, the screen of the streaming media rearview mirror is restored to the brightness before adjustment, and the transmittance of the dimming glass is restored to the transmittance before adjustment, that is, the screen is adjusted to the first initial brightness and the transmittance of the dimming glass is adjusted to the initial transmittance, so as to reduce the power consumption of the screen of the streaming media rearview mirror.

[0107] The implementation method for obtaining the second temperature may refer to the implementation method for obtaining the first temperature in the above embodiment, which will not be described in detail here.

[0108] Exemplarily, when the acquired second temperature is -9°C and the temperature threshold is -10°C, the first and second temperatures (-9°C) of the streaming media rearview mirror can be compared with the temperature threshold (-10°C). Since the second temperature (-9°C) of the streaming media rearview mirror is greater than the temperature threshold (-10°C), it can be determined that the streaming media rearview mirror is not within the preset temperature range. That is, in this case, the screen brightness can be restored from the target brightness to the first initial brightness according to the brightness adjustment value determined in the above embodiment, and the transmittance of the dimming glass can be restored from the first transmittance to the initial transmittance according to the light rate adjustment value determined in the above embodiment.

[0109] It should be noted that, when the second temperature is equal to or greater than the temperature threshold, that is, when the streaming media rearview mirror is not in the preset temperature range and can display images normally, it is considered that the ambient light intensity of the streaming media rearview mirror may change compared to the ambient light intensity when the streaming media rearview mirror is in the preset temperature range. Therefore, in order to ensure that the screen brightness of the media rearview mirror can adapt to the ambient light intensity of the streaming media rearview mirror, in other words, to avoid the situation where the screen brightness of the streaming media rearview mirror is too high or too low to affect the user's experience, in another possible implementation, the ambient light intensity of the streaming media rearview mirror can be obtained when the second temperature is equal to or greater than the temperature threshold; according to the preset relationship correspondence table, the second initial brightness of the screen corresponding to the ambient light intensity and the second transmittance of the dimming glass are determined, and the screen is adjusted to the second initial brightness corresponding to the ambient light intensity, and the transmittance of the dimming glass is adjusted to the second transmittance corresponding to the ambient light intensity, so as to ensure that the screen brightness of the media rearview mirror can adapt to the ambient light intensity of the streaming media rearview mirror, and avoid the situation where the screen brightness of the streaming media rearview mirror is too high or too low to affect the user's experience.

[0110] Among them, the implementation method of obtaining the ambient light intensity of the streaming media rearview mirror can be referred to the above embodiment, which will not be repeated here, and determining the second initial brightness of the screen and the second transmittance of the dimming glass corresponding to the ambient light intensity is the same as the implementation method of determining the first initial brightness and initial transmittance corresponding to the ambient light intensity according to the preset relationship correspondence table in the above embodiment, that is, it can also be referred to the above embodiment, which will not be repeated here.

[0111] Specifically, when the second temperature is equal to or greater than the temperature threshold, after determining the second initial brightness of the screen corresponding to the ambient light intensity and the second transmittance of the dimming glass, the screen brightness of the streaming media rearview mirror can be adjusted from the target brightness to the second initial brightness according to the brightness adjustment value, and the transmittance of the dimming glass can be adjusted from the first transmittance to the second transmittance according to the transmittance adjustment value, so as to ensure that the screen brightness of the media rearview mirror can adapt to the ambient light intensity of the streaming media rearview mirror, and avoid the situation where the screen brightness of the streaming media rearview mirror is too high or too low to affect the user experience. Among them, the brightness adjustment value is the difference obtained by subtracting the target brightness from the second initial brightness, and the transmittance adjustment value is the difference obtained by subtracting the first transmittance from the second transmittance.
