Description

Technical Field

[0001] The present disclosure relates to the technical field of vision protection, and in particular, to a screen dimming method, device, display device, dimming accessory, and dimming system. Background Art

[0002] Electronic display devices such as mobile phones and tablet computers have become an important part of people's lives. While these electronic display devices bring convenience to people's lives, they are also likely to cause damage to people's vision. Especially in a relatively dim environment, a bright area is formed on the screen side of the display device, while a dark area is formed on the environment side of the back of the display device. In this environment, the user's eyes are mainly affected by the ambient light brightness on the back of the display device, the pupil diameter is relatively large, and the screen of the display device is relatively bright, resulting in more light entering the human eye, which is likely to cause visual fatigue and affect the user's vision.

[0003] Currently, the screen of an electronic display device can be adjusted in brightness, but the area where the screen is located only accounts for a small part of the user's viewing angle. It is mainly the light on the back of the display device that affects the pupil size of the user. Therefore, adjusting the brightness of the screen has a relatively small impact on the comfort of the human eye, and the effect of improving visual fatigue is limited. Summary of the Invention

Detailed implementation manners

[0040] In order to more clearly understand the above objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments may be combined with each other.

[0041] In the following description, many specific details are set forth in order to fully understand the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

[0042] In the prior art, especially in a relatively dim light environment, usually the screen brightness of a display device is adjusted to improve the impact of light on the user's eyes. However, in such an environment, it is mainly due to the relatively dim ambient light brightness on the back of the display device that the pupil diameter of the user is relatively large, and more light enters the eyes, resulting in discomfort for the user. The light emitted by the screen of the display device only accounts for a small part of the user's viewing angle. Adjusting the screen brightness of the display device has a small impact on the pupil size. Therefore, still more light enters the eyes, resulting in poor comfort.

[0043] To solve the above problems, embodiments of the present disclosure provide a screen dimming method applicable to a display device. This method can be executed by the screen dimming device provided by the embodiments of the present disclosure, and the screen dimming device can be implemented in software and / or hardware. The screen dimming device can be integrated in the display device, and for example, it can be a control chip of the display device. The embodiments of the present disclosure do not limit the type of the display device. For example, it can be a display device such as a mobile phone or a tablet computer. Figure 1 It is a schematic flowchart of a screen dimming method provided by an embodiment of the present disclosure. Refer to Figure 1 , the screen dimming method includes S110 - S130: S110. Obtain the ambient light brightness on the back of the display device.

[0044] S120. Adjust the screen brightness of the display device according to the ambient light brightness on the back of the display device.

[0045] Exemplarily, the ambient light on the back of the display device occupies the main part of the user's viewing angle. Therefore, the ambient light brightness will affect the pupil size of the user. The brighter the ambient light brightness, the smaller the diameter of the pupil; the darker the ambient light brightness, the larger the diameter of the pupil. And when the pupil sizes are different, there are differences in the light flux entering the human eye, the degree of influence of light on the human eye is different, and the perceived comfort of the human eye is different. So, the ambient light brightness on the back of the display device can be obtained, and then a series of adjustments can be made based on the ambient light brightness to make the human eye in a more comfortable environment when using the display device. In subsequent embodiments, optional implementation manners will be illustrated by examples. The embodiments of the present disclosure do not make specific limitations on how to obtain the ambient light brightness on the back of the display device.

[0046] When a user uses a display device, the light emitted by the screen of the display device will shine on the human eye. If the ambient light brightness on the back of the current display device is relatively dark, the pupil of the human eye will dilate to adapt to this darker environment. However, if the screen brightness of the display device is relatively bright at this time, it will cause a relatively large light flux to enter the human eye. In this way, it is easy to cause visual fatigue and affect the visual health of the user when watching the display screen for a long time. And the size of the pupil of the human eye depends on the ambient light brightness on the back of the display device. There is a certain correspondence between the ambient light brightness on the back of the display device and the screen brightness of the display device. Therefore, based on the ambient light brightness on the back of the display device, the screen brightness of the display device is adjusted to lower the screen brightness, thereby changing the light flux entering the human eye.

[0047] S130. Based on the screen brightness of the display device being adjusted to the lowest display brightness and the ambient light brightness on the back of the display device being lower than the ambient light brightness matching the lowest display brightness, control to supplement light to the back environment of the display device to adjust the ambient light brightness on the back of the display device.

[0048] Specifically, there is a matching relationship between the ambient light brightness on the back of the display device and the screen brightness of the display device. When this matching relationship is met, the user's eyes are more comfortable when using the display device. Therefore, the relationship between the ambient light brightness on the back of the display device and the ambient light brightness matching the screen brightness when the screen brightness of the display device is at the lowest display brightness can be compared. If the ambient light brightness on the back of the display device is still lower than the ambient light brightness matching the lowest display brightness, it can be understood that after adjusting the screen brightness of the display device, it is still relatively bright. However, the screen brightness of the display device cannot be adjusted indefinitely. Currently, it has been adjusted to the lowest display brightness and cannot be changed further. That is, the ambient light brightness is still relatively dark, the screen brightness is still relatively bright, but the screen brightness cannot be further reduced. Therefore, control the ambient light supplement to the back of the display device to adjust the ambient light brightness on the back of the display device. By increasing the ambient light brightness, the ambient light brightness of the display device is made more matched with the screen brightness of the display device, improving the comfort of the user's eyes.

[0049] It should be noted that the embodiments of the present disclosure do not limit how to supplement ambient light to the back of the display device. A light-emitting element, such as a light-emitting diode, can be set, or the original structure of the display device can be used. Specific alternative implementation methods can be referred to in the following text and will not be elaborated here.

[0050] The embodiments of the present disclosure adjust the screen brightness of the display device to the lowest display brightness based on the ambient light brightness on the back of the display device, reducing the brightness of the display screen. However, when the screen brightness of the display device is adjusted to the lowest display brightness, the ambient light brightness on the back of the display device is still lower than the ambient light brightness matching the lowest display brightness, resulting in discomfort for the user's eyes. Therefore, it is also necessary to supplement ambient light to the back of the display device to adjust the ambient light brightness on the back of the display device, so as to increase the ambient light brightness on the back of the display device, improve the eye use environment, enhance the eye comfort when the user uses the display device, avoid visual fatigue, and play a role in protecting eyesight.

[0051] The embodiments of the present disclosure are implemented by the display device to execute the screen dimming method. In the current application scenario, the user is using the display device. Therefore, the screen dimming method can be executed through the display device. Among them, a corresponding application program is set on the display device, and the adjustment operation can be performed using this application program. Since there is a control chip in the display device, the original control chip of the display device can also be used to load the screen dimming method and execute the specific method steps, without the need to additionally add structures such as a control chip for control.

[0052] In some embodiments, based on the screen brightness of the display device being adjusted to the lowest display brightness and the ambient light brightness on the back of the display device being lower than the ambient light brightness matching the lowest display brightness, controlling the ambient light supplement to the back of the display device to adjust the ambient light brightness on the back of the display device includes: Based on the screen brightness of the display device being adjusted to the lowest display brightness, and the ambient light brightness on the back of the display device being lower than the ambient light brightness matching the lowest display brightness, control the emission brightness of the ambient light supplement for the back of the display device according to the ambient light brightness on the back of the display device, so that the ambient light brightness on the back of the display device matches the lowest display brightness of the screen.

[0053] Specifically, after the screen brightness of the display device is adjusted to the lowest display brightness, the screen brightness still does not match the ambient light brightness, and it is impossible to bring a more comfortable environment for the user to use the display device. The embodiments of the present disclosure continue to adjust by adjusting the ambient light on the back of the display device.

[0054] Control the ambient light supplement for the back of the display device according to the ambient light brightness on the back of the display device, increase the ambient light brightness, thereby reducing the pupil size of the user, and the light flux entering the pupil will also decrease, improving the comfort of eye use. When supplementing the ambient light for the back of the display device, the emission brightness of the ambient light supplement for the back of the display device can be controlled according to the ambient light brightness on the back of the display device. Since there is a matching relationship between the ambient light brightness on the back of the display device and the screen brightness, and the current screen is at the lowest display brightness, therefore, taking the ambient light brightness matching the lowest display brightness of the screen as the target reference, adjust the ambient light brightness on the back of the display device so that the ambient light brightness on the back of the display device matches the lowest display brightness of the screen. Among them, the matching relationship between the ambient light brightness on the back of the display device and the screen brightness can be achieved by means of an algorithm, or can be achieved by a table of the corresponding relationship between the two. For example, there is a matching relationship between the ambient light brightness and the screen brightness, which can be a matching algorithm for the ambient light brightness and the screen brightness. Therefore, adjusting the matching relationship between the ambient light brightness and the screen brightness essentially adjusts the matching algorithm between the ambient light brightness and the screen brightness. In some embodiments, there is a matching relationship between the ambient light brightness and the screen brightness, which can be a matching table for the ambient light brightness and the screen brightness. Adjusting the matching relationship between the ambient light brightness and the screen brightness essentially adjusts the matching table between the ambient light brightness and the screen brightness. In addition, if the gap between the current ambient light brightness and the ambient light brightness matching the lowest display brightness of the screen is large, the emission brightness during light supplementation can be large. If the gap is small, the emission brightness during light supplementation can also be correspondingly small. The emission brightness during light supplementation can be controlled according to the ambient light brightness on the back of the display device to make the light supplementation effect better.

[0055] There are various ways to control the luminous brightness during supplementary lighting. For example, the power of the lighting module that realizes the supplementary lighting function can be controlled to adjust the luminous brightness of the supplementary lighting. Different powers of the lighting module result in different light brightnesses generated by the lighting module. The greater the power, the greater the light brightness generated by the lighting module, that is, the greater the luminous brightness of the supplementary lighting. The smaller the power, the smaller the light brightness generated by the lighting module, that is, the smaller the luminous brightness of the supplementary lighting. Therefore, the luminous brightness of the ambient supplementary lighting on the back of the display device can be adjusted by regulating the power of the lighting module.

[0056] Optionally, the luminous brightness of the supplementary lighting is adjusted by controlling the number of lighting modules that realize the supplementary lighting function. Among them, the number of lighting modules can be set according to actual needs. One lighting module can be set, and the generated light brightness is smaller, saving power consumption; multiple lighting modules can also be set, and the generated light brightness is greater, distributed in different areas to make the supplementary lighting more uniform and improve the supplementary lighting effect. It can be specifically set according to actual needs.

[0057] It should be noted that the embodiments of the present disclosure do not specifically limit how to control the luminous brightness of the ambient supplementary lighting on the back of the display device. The above are only some feasible implementation manners for illustrative purposes. The embodiments of the present disclosure do not limit the specific manner of adjusting the matching relationship between the ambient light brightness and the screen brightness. The above embodiments are only for illustrative purposes.

[0058] In some embodiments, it further includes: Configure the lowest display brightness according to the lowest screen brightness information set by the user.

[0059] Exemplarily, when the screen brightness of the display device is adjusted to the lowest display brightness, and the ambient light brightness on the back of the display device is lower than the ambient light brightness matched with the lowest display brightness, then the ambient supplementary lighting on the back of the display device will be controlled. However, different users' eyes have different sensitivities to light. If the same lowest display brightness is configured for all display devices, some users are more comfortable at this lowest display brightness, so there is no need to supplement the light for the environment on the back of the display device. But there are also some users with more sensitive eyes who are not comfortable at this lowest display brightness and need to supplement the light for the environment on the back of the display device. Therefore, the lowest display brightness in the embodiments of the present disclosure can be set according to the user's needs. The user can set the lowest screen brightness information by himself / herself to configure the lowest display brightness that meets his / her own needs, so as to control the supplementary lighting timing and enable different users to keep their eyes in a comfortable state, improving the user's comfort and experience.

[0060] In some embodiments, it further includes: Based on the adjustment operation of the matching relationship between the ambient light brightness and the screen brightness received by the user interface, adjust the matching relationship between the ambient light brightness and the screen brightness.

[0061] Exemplarily, it is mentioned above that there is a certain matching relationship between the ambient light brightness and the screen brightness. When the matching relationship is satisfied, the user is most comfortable using the display device in this case. However, different users have different requirements for the matching relationship between the ambient light brightness and the screen brightness. Therefore, the matching relationship between the ambient light brightness and the screen brightness can also be adjusted according to the user's needs.

[0062] For example, the display device is provided with a user interface, and the user can perform an operation to adjust the matching relationship between the ambient light brightness and the screen brightness on the user interface, so that the matching relationship between the ambient light brightness and the screen brightness meets the user's own needs. After the user interface receives the adjustment operation of the user, it will adjust the matching relationship between the ambient light brightness and the screen brightness to meet the user's needs.

[0063] In some embodiments, based on the operation to adjust the matching relationship between the ambient light brightness and the screen brightness received by the user interface, adjusting the matching relationship between the ambient light brightness and the screen brightness includes: Obtaining the operation to adjust the matching relationship between the ambient light brightness and the screen brightness based on the first adjustment control displayed on the user interface, and adjusting the matching relationship between the ambient light brightness and the screen brightness based on the operation to adjust the matching relationship between the ambient light brightness and the screen brightness.

[0064] Exemplarily, Figure 2 is a schematic diagram of a user interface provided by an embodiment of the present disclosure. Referring to Figure 2 , a first adjustment control is provided on the user interface. By controlling the first adjustment control, the matching relationship between the ambient light brightness and the screen brightness can be changed. When the slider in the first adjustment control is in different positions, the matching relationship between the ambient light brightness and the screen brightness is different. Therefore, the user can perform an operation to adjust the matching relationship between the ambient light brightness and the screen brightness by sliding the slider on the first adjustment control, and the first adjustment control displayed on the user interface can obtain the operation to adjust the matching relationship between the ambient light brightness and the screen brightness performed by the user. Then, the display device adjusts the matching relationship between the ambient light brightness and the screen brightness based on the above operation to meet the adjusted matching relationship of the user.

[0065] Optionally, continuing to refer to the schematic diagram of the user interface shown in Figure 2 , a first switch control is also provided. When "on" is selected, the first adjustment control is turned on, and the user can use the first adjustment control to adjust the matching relationship between the ambient light brightness and the screen brightness, such as moving the slider for adjustment; when "off" is selected, the first adjustment control is turned off, and at this time, the matching relationship between the ambient light brightness and the screen brightness cannot be adjusted, and sliding the slider can only adjust the screen brightness. A screen brightness bar is provided below the first adjustment control for displaying the current screen brightness. When the matching relationship between the ambient light brightness and the screen brightness changes, the screen brightness will change accordingly. Therefore, the screen brightness can be referred to the screen brightness bar corresponding to the lower part of the slider. For example,Figure 2 There are 10 screen brightness levels set. "1" represents the brightest screen brightness, and "10" represents the darkest screen brightness. The screen brightness gradually dims from 1 to 10. The screen brightness bar can also be represented by different grayscales. For example, the gray scale is the lightest at "1" and the darkest at "10", etc. When the first adjustment control is at 10, based on the matching relationship between the current ambient light brightness and the screen brightness, the screen brightness is the darkest. If the user feels uncomfortable and wants to adjust the matching relationship between the ambient light brightness and the screen brightness, they can slide the slider on the first adjustment control to perform the adjustment operation of the matching relationship between the ambient light brightness and the screen brightness. For example, moving the slider to "5", the first adjustment control can obtain the adjustment operation of the matching relationship between the ambient light brightness and the screen brightness performed by the user, and then display that the device adjusts the matching relationship between the ambient light brightness and the screen brightness based on the above operation. As the matching relationship between the ambient light brightness and the screen brightness changes, the screen brightness will also change accordingly. At this time, the screen brightness will become brighter to meet the user's needs.

[0066] Among them, Figure 2 the first adjustment control in is a slider bar. In different embodiments, the first adjustment control can also be various possible forms such as a circular slider bar, an input box, a button, etc., and is not limited to Figure 2 the rectangular slider bar shown.

[0067] In some embodiments, it further includes: adjusting the ambient light compensation threshold based on the ambient light compensation threshold adjustment operation received by the user interface; among them, the ambient light compensation threshold is the ambient light brightness matching the lowest display brightness.

[0068] In the embodiments of the present disclosure, the user can also adjust the ambient light compensation threshold according to their own needs. Here, the ambient light compensation threshold is the ambient light brightness matching the lowest display brightness mentioned above. When the ambient light brightness on the back of the display device is lower than the ambient light compensation threshold, it means that the current environment is too dark. Even after adjusting the screen brightness of the display device, the ambient light brightness on the back of the display device is still too low, resulting in discomfort to the human eye. Therefore, it is necessary to perform ambient light compensation on the back of the display device to adjust the ambient light brightness on the back of the display device. However, also because different users have different sensitivities to light, when the ambient light compensation threshold is A, some users feel uncomfortable in their eyes, while some users do not feel discomfort. Therefore, in order to adapt to different users and meet the needs of different users, the ambient light compensation threshold can be adjusted to match the user's own needs.

[0069] Similarly, a user interface can be set on the display device. The user can perform the ambient light compensation threshold adjustment operation on the user interface so that the ambient light compensation threshold meets their own needs. After the user interface receives the adjustment operation of the user, it will adjust the ambient light compensation threshold.

[0070] In some embodiments, adjusting the ambient fill light threshold based on a fill light threshold adjustment operation received through a user interface includes: Obtaining a fill light threshold adjustment operation based on a second adjustment control displayed on the user interface, and adjusting the ambient fill light threshold based on the fill light threshold adjustment operation.

[0071] Exemplarily, Figure 3 FIG. is a schematic diagram of another user interface provided by an embodiment of the present disclosure. Referring to Figure 3 , a second adjustment control is provided on the user interface. By controlling the second adjustment control, the ambient fill light threshold can be adjusted. When the slider in the second adjustment control is in different positions, the ambient fill light threshold is different. Therefore, the user can perform a fill light threshold adjustment operation by sliding the slider on the second adjustment control. The second adjustment control displayed on the user interface can obtain the fill light threshold adjustment operation performed by the user, and then the display device adjusts the ambient fill light threshold based on the above operation to meet the needs of different users.

[0072] Optionally, continuing to refer to the schematic diagram of the user interface shown in Figure 3 , a second switch control is also provided. When "on" is selected, the second adjustment control is turned on, and the user can use the second adjustment control to adjust the ambient fill light threshold. When "off" is selected, the second adjustment control is turned off, and at this time, the ambient fill light threshold cannot be adjusted. Different brightness levels are marked below the second condition control, such as 0, 5, 10, 15, and 20. When the slider is at 0, it means that the ambient fill light threshold is 0 lux at this time, that is, fill light is performed when the ambient light brightness matching the lowest display brightness is 0 lux. When the slider is at 20, it means that the ambient fill light threshold is 20 lux at this time, that is, fill light is performed when the ambient light brightness matching the lowest display brightness is 20 lux. In the above example, the ambient light brightness corresponding to 0 is darker, and the ambient light brightness corresponding to 20 is brighter. The user can set according to actual needs, and the above is only for illustrative purposes.

[0073] Among them, Figure 3 the first adjustment control in is a sliding bar. In different embodiments, the first adjustment control can also be various possible forms such as a circular sliding bar, an input box, a button, etc., and is not limited to the rectangular sliding bar shown in Figure 3 .

[0074] In some embodiments, before controlling the ambient fill light on the back of the display device, it further includes: determining that the screen of the display device is in a display working state.

[0075] The purpose of controlling the ambient light compensation on the back of the display device in the embodiments of the present disclosure is to make the environment for users to use the display device more comfortable and avoid eye fatigue of users. Therefore, the prerequisite for light compensation is that the user is using the display device. Furthermore, there will be a problem that the ambient light brightness on the back of the display device does not match the screen brightness of the display device, resulting in discomfort and fatigue of the user's eyes. Therefore, before controlling the ambient light compensation on the back of the display device, it is necessary to determine whether the screen of the display device is in the display working state. If the screen of the display device is not in the display working state, it can be understood that the user is not using the display device at this time, so there is no need to compensate the ambient light on the back of the display device. If it is determined that the screen of the display device is in the display working state, it can be understood that the user is using the display device. Therefore, the screen dimming method provided by the embodiments of the present disclosure can be executed. If there is a need, the ambient light compensation on the back of the display device can be controlled. This can not only save power but also provide a more comfortable environment for users when they use the display device.

[0076] As mentioned above, subsequent dimming operations are to be based on the ambient light brightness on the back of the display device. Optionally, in some embodiments, a dimming accessory is provided on the back of the display device, and the dimming accessory includes an ambient light brightness sensing module. In the embodiments of the present disclosure, the dimming accessory and the display device jointly implement the steps described in the screen dimming method.

[0077] Correspondingly, the step of obtaining the ambient light brightness on the back of the display device includes: obtaining the ambient light brightness on the back of the display device collected by the ambient light brightness sensing module of the dimming accessory.

[0078] Exemplarily, Figure 4 FIG. is a schematic structural diagram of a dimming accessory provided in the embodiments of the present disclosure. Refer to Figure 4 , a dimming accessory 6 is provided on the back of the display device, and the dimming accessory 6 includes an ambient light brightness sensing module 61. Thus, the ambient light brightness sensing module 61 can sense the ambient light on its side, that is, collect the ambient light brightness on the back of the display device. And the display device and the dimming accessory 6 can interact and perform data transmission. Therefore, the display device can obtain the ambient light brightness on the back of the display device collected by the ambient light brightness sensing module 61 of the dimming accessory 6, and then perform subsequent dimming operations based on this ambient light brightness.

[0079] It should be noted that the embodiments of the present disclosure do not limit the specific structure of the dimming accessory. It may only include an ambient light brightness sensing module, or may include other modules, which can be designed according to actual needs. Among them, the ambient light brightness sensing module can be an ambient light sensor for measuring the intensity of surrounding light, or other devices can be used to measure the ambient light brightness.

[0080] In some embodiments, continue to refer to Figure 4, the dimming accessory 6 further includes a light-emitting module 62; based on the screen brightness of the display device being adjusted to the lowest display brightness, and the ambient light brightness on the back of the display device being lower than the ambient light brightness matching the lowest display brightness, controlling the ambient light compensation for the back of the display device to adjust the ambient light brightness on the back of the display device includes: Based on the screen brightness of the display device being adjusted to the lowest display brightness, and the ambient light brightness on the back of the display device being lower than the ambient light brightness matching the lowest display brightness, send an ambient light brightness adjustment instruction to the dimming accessory 6, so that the dimming accessory controls the light-emitting module 62 to emit light according to the ambient light brightness adjustment instruction.

[0081] Exemplarily, the dimming accessory 6 provided in the embodiments of the present disclosure includes an ambient light brightness sensing module 61 and a light-emitting module 62. Since the dimming accessory 6 is located on the back of the display device, both the ambient light brightness sensing module 61 and the light-emitting module 62 are located on the back of the display device. The ambient light brightness sensing module 61 is still used to collect the ambient brightness on the back of the display device. Based on the information interaction between the dimming accessory 6 and the display device, the display device can obtain the ambient light brightness on the back of the display device collected by the ambient light brightness sensing module 61 of the dimming accessory 6, so as to compare the ambient light brightness on the back of the display device with the ambient light brightness matching after the screen brightness of the display device is adjusted to the lowest display brightness.

[0082] If the ambient light brightness on the back of the display device is lower than the ambient light brightness matching the lowest display brightness, it means that the ambient light brightness on the back of the display device is relatively dim. When the user uses the display device in the current scenario, it will cause discomfort to the eyes and be prone to fatigue. Therefore, it is necessary to compensate the ambient light for the back of the display device to adjust the ambient light brightness on the back of the display device. Based on the fact that the dimming accessory 6 can interact with the display device and the dimming accessory 6 includes a light-emitting module 62, the display device sends an ambient light brightness adjustment instruction to the dimming accessory 6. Then, the light-emitting module 62 on the dimming accessory 6 emits light according to the ambient light brightness adjustment instruction sent by the display device to compensate the ambient light for the back of the display device, improve the ambient light brightness on the back of the display device, and improve the user's eye use environment.

[0083] Optionally, by controlling the power of the light-emitting module that realizes the light compensation function, the light emission brightness of the light compensation is adjusted. Different powers of the light-emitting module result in different light brightnesses generated by the light-emitting module. The greater the power, the greater the light brightness generated by the light-emitting module, that is, the greater the light emission brightness of the light compensation. The smaller the power, the smaller the light brightness generated by the light-emitting module, that is, the smaller the light emission brightness of the light compensation.

[0084] Alternatively, the luminous intensity of fill light is adjusted by controlling the number of luminous modules that implement the fill light function. Among them, the number of luminous modules can be set according to actual requirements. One luminous module can be set, and the generated light intensity is smaller, saving power consumption. Multiple luminous modules can also be set, and the generated light intensity is larger, distributed in different areas, making the fill light more uniform and improving the fill light effect. Specifically, it can be set according to actual requirements.

[0085] In some embodiments, before obtaining the ambient light intensity on the back of the display device, it further includes: obtaining the graphic code on the dimming accessory, identifying the dimming accessory, and establishing a communication connection with the dimming accessory.

[0086] In the embodiments of the present disclosure, the ambient light intensity on the back of the display device is collected by the dimming accessory. Therefore, before the display device obtains the ambient light intensity on the back of the display device from the dimming accessory, it is necessary to complete the communication connection between the dimming accessory and the display device to achieve information interaction.

[0087] Exemplarily, a graphic code is set on the dimming accessory, for example, on the back of the dimming accessory. The display device obtains the image code on the dimming accessory, can download the application program (APP) for controlling the dimming accessory. After the download and installation are completed, open the application program, click "Add Device", scan the graphic code again to identify the dimming accessory, and add it to "My Devices". Next, it is necessary to establish a communication connection between the display device and the dimming accessory. For example, click "Go to Connect" in the application program of the dimming accessory to establish their communication connection, such as achieving a Bluetooth connection. After the connection is successful, the position where "Go to Connect" is located will be displayed as "Controlling", and the dimming accessory enters the working state and can achieve information interaction with the display device. If the connection fails, you can reconnect according to the pop-up prompt.

[0088] Among them, the graphic code can be a two-dimensional code, a bar code, or a code used in other specific fields, etc. The communication connection can be a Bluetooth connection. The embodiments of the present disclosure do not limit the type of image code and the type of communication connection.

[0089] In the above embodiments, the ambient light intensity sensing module is set in the dimming accessory. In other application scenarios, the ambient light intensity sensing module can also be set in the display device, and there is no need to perform data transmission through the interaction between the dimming accessory and the display device.

[0090] Optionally, in some embodiments, an ambient light intensity sensing module is integrated on the back of the display device; obtaining the ambient light intensity on the back of the display device includes: obtaining the ambient light intensity on the back of the display device collected by the ambient light intensity sensing module of the display device.

[0091] Exemplarily, an ambient light luminance sensing module is integrated on the back of the display device, and the ambient light luminance sensing module collects the ambient light luminance on the back of the display device. Since the display device itself integrates this module, the display device can directly obtain the ambient light luminance collected by the ambient light luminance sensing module integrated on its back without interacting with other components, simplifying the method steps for obtaining the ambient light luminance. Further, the display device can perform subsequent dimming operations based on the obtained ambient light luminance on the back of the display device.

[0092] Optionally, the ambient light luminance sensing module in the embodiments of the present disclosure may be an ambient light sensor for measuring the intensity of surrounding light, or other devices may be used to measure the ambient light luminance. In addition, the specific position of the ambient light luminance sensing module on the back of the display device in the embodiments of the present disclosure is not limited and can be set according to actual requirements and the space of the display device.

[0093] In some embodiments, a light emitting module is integrated on the back of the display device; based on the screen brightness of the display device being adjusted to the lowest display brightness and the ambient light luminance on the back of the display device being lower than the ambient light luminance matching the lowest display brightness, controlling the backlight compensation for the environment of the display device to adjust the ambient light luminance on the back of the display device includes: Based on the screen brightness of the display device being adjusted to the lowest display brightness and the ambient light luminance on the back of the display device being lower than the ambient light luminance matching the lowest display brightness, driving the light emitting module of the display device to emit light.

[0094] Exemplarily, the display device provided in the embodiments of the present disclosure integrates an ambient light luminance sensing module and a light emitting module on the back. The ambient light luminance sensing module is still used to collect the ambient light luminance on the back of the display device. The display device can directly obtain the ambient light luminance collected by the ambient light luminance sensing module integrated on its back, and thus compare the ambient light luminance on the back of the display device with the ambient light luminance matching the lowest display brightness after the screen brightness of the display device is adjusted to the lowest display brightness.

[0095] If the ambient light luminance on the back of the display device is lower than the ambient light luminance matching the lowest display brightness, it means that the ambient light luminance on the back of the display device is relatively dim. When the user uses the display device in the current scenario, it will cause discomfort to the eyes and is prone to fatigue. Therefore, it is necessary to perform backlight compensation for the environment of the display device to adjust the ambient light luminance on the back of the display device. In the embodiments of the present disclosure, the light emitting module is integrated on the back of the display device. Therefore, the display device can directly drive the light emitting module located on its back to emit light to perform backlight compensation for the environment of the display device, improve the ambient light luminance on the back of the display device, and improve the user's eye use environment. Since the display device itself integrates the light emitting module, when using the light emitting module to perform backlight compensation for the environment of the display device, it is also unnecessary to interact with other components, simplifying the method steps for backlight compensation.

[0096] There are various ways to control the emission brightness during supplementary lighting. For example, the power of the light-emitting module that realizes the supplementary lighting function can be controlled to adjust the emission brightness of the supplementary lighting. The number of light-emitting modules that realize the supplementary lighting function can be controlled to adjust the emission brightness of the supplementary lighting. In the embodiments of the present disclosure, the position of the light-emitting module is not limited and can be set according to actual needs. In other embodiments, the light-emitting module can also use the original structure of the display device, which will be described in detail later.

[0097] The ambient light brightness sensing module mentioned in the above embodiments can be integrated in the display device. In some optional embodiments, the original modules or structures of the display device can be reused. Optionally, in some embodiments, the rear camera module of the display device is reused as the ambient light brightness sensing module; obtaining the ambient light brightness on the back of the display device collected by the ambient light brightness sensing module of the display device includes: Obtaining an ambient image on the back of the display device through the rear camera module of the display device; Determining the ambient light brightness on the back of the display device according to the ambient image on the back of the display device.

[0098] When the display device includes a rear camera module, for example, the display device is a mobile phone, the rear camera module can be reused as the ambient light brightness sensing module, and the ambient light brightness on the back of the display device can be collected through the rear camera module.

[0099] Specifically, the rear camera module is located on the back of the display device and is usually used to obtain image information. Therefore, the ambient image on the back of the display device can be obtained by using the rear camera module of the display device. When the rear camera module is under different ambient light brightnesses, the corresponding image gray levels of the obtained ambient images are different. Therefore, the corresponding image gray level can be recognized according to the ambient image on the back of the display device, and the ambient light brightness on the back of the display device can be determined according to the image gray level. Since the display device reuses its own original rear camera module to realize the function of the ambient light brightness sensing module, there is no need to additionally set an ambient light brightness sensing module, which saves the overall cost.

[0100] It should be noted that the specific type of the display device in the embodiments of the present disclosure is not limited and can be a mobile phone or various display devices with a rear camera module such as a tablet computer.

[0101] Similarly, the light-emitting module mentioned in the above embodiments can be integrated in the display device. In some optional embodiments, the original modules or structures of the display device can be reused. Optionally, in some embodiments, the rear lighting module of the display device is reused as the light-emitting module; based on the screen brightness of the display device being adjusted to the lowest display brightness and the ambient light brightness on the back of the display device being lower than the ambient light brightness matching the lowest display brightness, driving the light-emitting module of the display device to emit light includes: Based on the screen brightness of the display device being adjusted to the lowest display brightness, and the ambient light brightness on the back of the display device being lower than the ambient light brightness matching the lowest display brightness, drive the rear illumination module of the display device to emit light.

[0102] When the display device has a rear illumination module, for example, when the display device is a mobile phone and there is a flashlight on the back of the mobile phone, this flashlight serves as the rear illumination module, and the rear illumination module can be reused as a light-emitting module. The display device can drive the rear illumination module to emit light to supplement the light for the environment on the back of the display device.

[0103] Specifically, the rear illumination module is located on the back of the display device and is usually used for illumination in a dim environment. Therefore, the rear illumination module of the display device can be used to supplement the light for the display device. For example, when the ambient light brightness on the back of the display device is lower than the ambient light brightness matching the lowest display brightness, the ambient light brightness on the back of the display device is relatively dim. When the user uses the display device in the current scenario, it will cause discomfort to the eyes and be prone to fatigue. Therefore, it is necessary to supplement the light for the environment on the back of the display device to adjust the ambient light brightness on the back of the display device. At this time, the display device can drive the rear illumination module of the display device to emit light to supplement the light for the environment on the back of the display device, improve the ambient light brightness on the back of the display device, and improve the user's eye use environment. Since the display device reuses its own original rear illumination module to achieve the function of the light-emitting module, there is no need to additionally set up a light-emitting module, saving the overall cost.

[0104] Optionally, since the position of the rear illumination module of the display device is fixed, a light-emitting module can also be additionally set up to supplement the light together with the rear illumination module to improve the light supplement effect. The embodiments of the present disclosure do not limit this.

[0105] The embodiments of the present disclosure also provide a screen dimming device, which is integrated or loaded in the display device. Figure 5 For the structural block diagram of a screen dimming device provided by the embodiments of the present disclosure, see Figure 5 , the screen dimming device includes: an ambient light brightness acquisition module 21, a screen brightness adjustment module 22, and a light supplement control module 23.

[0106] The ambient light brightness acquisition module 21 is used to acquire the ambient light brightness on the back of the display device. The screen brightness adjustment module 22 is used to adjust the screen brightness of the display device according to the ambient light brightness on the back of the display device. The light supplement control module 23 is used to control the light supplement for the environment on the back of the display device based on the screen brightness of the display device being adjusted to the lowest display brightness and the ambient light brightness on the back of the display device being lower than the ambient light brightness matching the lowest display brightness, so as to adjust the ambient light brightness on the back of the display device.

[0107] The embodiments of the present disclosure also provide a display device. Figure 6 For the structural schematic diagram of a display device provided by the embodiments of the present disclosure, refer toFigure 6 , including a processor and a memory. Instructions are stored in the memory for the processor to execute. When the processor executes the instructions, the arbitrary screen dimming method in the above embodiments is implemented. Specifically, as Figure 6 shown, it can be set that the vehicle includes at least one processor 302, at least one memory 301, and at least one communication interface 303. Each component in the display device is coupled together through a bus system 304. The communication interface 303 is used for data transmission with external devices. It can be understood that the bus system 304 is used to realize the connection and communication between these components. In addition to the data bus, the bus system 304 also includes a power bus, a control bus, and a status signal bus. However, for the sake of clear illustration, in Figure 6 all kinds of buses are labeled as the bus system 304.

[0108] It can be understood that the memory 301 in this embodiment can be a volatile memory or a non-volatile memory, or can include both volatile and non-volatile memories. In some embodiments, the memory 301 stores the following elements: executable units or data structures, or subsets thereof, or extended sets thereof, an operating system, and applications. In the embodiments of the present disclosure, the processor 302 executes the steps of the screen dimming method provided in the embodiments of the present disclosure by calling the programs or instructions stored in the memory 301.

[0109] The method provided in the embodiments of the present disclosure can be applied to the processor 302 or implemented by the processor 302. The processor 302 can be an integrated circuit chip with signal processing capabilities. In the implementation process, the steps of the above method can be completed by the integrated logic circuit in the hardware of the processor 302 or by instructions in software form. The above-mentioned processor 302 can be a general-purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components. The general-purpose processor can be a microprocessor or the processor can also be any conventional processor, etc.

[0110] The steps of the method provided by the embodiments of the present disclosure can be directly implemented by a hardware decoding processor, or implemented by a combination of hardware and software units in the decoding processor. The software unit can be located in a mature storage medium in the art such as a random access memory, a flash memory, a read-only memory, a programmable read-only memory, or an electrically erasable programmable memory, a register, etc. This storage medium is located in the memory 301, and the processor 302 reads the information in the memory 301 and combines its hardware to complete the steps of the method.

[0111] In some embodiments, an ambient light luminance sensing module and a light emitting module are integrated on the back of the display device; the acquisition surface of the ambient light luminance sensing module and the light emitting surface of the light emitting module face away from the display surface of the display device.

[0112] Exemplarily, an ambient light luminance sensing module and a light emitting module are integrated on the back of the display device. The ambient light luminance sensing module is used to collect the ambient light luminance on the back of the display device. Therefore, in order to fully collect the ambient light luminance on the back of the display device, the acquisition surface of the ambient light luminance sensing module faces away from the display surface of the display device, that is, the acquisition surface faces the back environment to avoid being blocked and affecting the acquisition effect. The light emitting module is used to supplement light to the environment on the back of the display device when the ambient light luminance on the back of the display device is lower than the ambient light luminance matching the lowest display luminance. Therefore, the light emitting surface of the light emitting module should face away from the display surface of the display device to make the light diverge outward and supplement light to the environment on the back of the display device.

[0113] In some embodiments, the rear camera module of the display device is reused as the ambient light luminance sensing module.

[0114] Exemplarily, some display devices have a rear camera module. For example, display devices such as mobile phones and tablet computers all have a rear camera module located on the back of the display device, and the acquisition surface of the rear camera module faces away from the display surface of the display device, and is usually used to capture images on the back of the display device. Based on this, the rear camera module of the display device can be reused as the ambient light luminance sensing module, and the rear camera module of the display device can be used to obtain the ambient image on the back of the display device. When the rear camera module is in different ambient light luminances, the corresponding image gray levels of the obtained ambient images are different. Therefore, the corresponding image gray level can be identified according to the ambient image on the back of the display device, and the ambient light luminance on the back of the display device can be determined according to the image gray level. Since the display device reuses its own original rear camera module to implement the function of the ambient light luminance sensing module, there is no need to additionally set an ambient light luminance sensing module, saving the overall cost.

[0115] In some embodiments, the rear lighting module of the display device is reused as the light emitting module.

[0116] Exemplarily, some display devices have a rear lighting module. For example, display devices such as mobile phones and tablets all have a rear lighting module, which is located on the back of the display device, and the light-emitting surface of the rear lighting module faces away from the display surface of the display device, and is usually used for lighting in a dim environment. Based on this, the rear lighting module of the display device can be reused as a light-emitting module. If the ambient light brightness on the back of the display device is lower than the ambient light brightness matched with the lowest display brightness, the ambient light brightness on the back of the display device is relatively dim, and the user's use of the display device in the current scenario will cause discomfort to the eyes and is prone to fatigue. Therefore, the display device can drive the rear lighting module of the display device to emit light to supplement the ambient light on the back of the display device, improve the ambient light brightness on the back of the display device, and improve the user's eye use environment. Since the display device reuses its original rear lighting module to implement the function of the light-emitting module, there is no need to additionally set up a light-emitting module, saving the overall cost.

[0117] An embodiment of the present disclosure further provides a screen dimming method, which is applicable to a dimming accessory. This method can be executed by a module or chip with control or processing functions in the dimming accessory. Figure 7 For the structural schematic diagram of another screen dimming method provided by an embodiment of the present disclosure, refer to Figure 7 , the screen dimming method includes S410 - S420: S410. Send the ambient light brightness on the back of the display device collected by the ambient light brightness sensing module to the display device, so that the display device adjusts the screen brightness according to the ambient light brightness.

[0118] S420. Receive the ambient light brightness adjustment instruction sent by the display device, and control the light-emitting module to emit light to adjust the ambient light brightness on the back of the display device.

[0119] Wherein, a dimming accessory is provided on the back of the display device, and the dimming accessory includes an ambient light brightness sensing module and a light-emitting module; the collection surface of the ambient light brightness sensing module and the light-emitting surface of the light-emitting module face away from the display surface of the display device; the ambient light brightness adjustment instruction is sent when the display device adjusts the screen brightness to the lowest display brightness and the ambient light brightness on the back of the display device is lower than the ambient light brightness matched with the lowest display brightness.

[0120] Exemplarily, when a user uses a display device, the light emitted by the screen of the display device irradiates the human eyes. If the ambient light brightness on the back of the current display device is relatively dim, the pupil of the human eye will dilate in order to adapt to this darker environment. However, if the screen brightness of the display device is relatively high at this time, it will result in a relatively large light flux entering the human eyes. Thus, it is very easy to cause visual fatigue and affect the visual health of the user when watching the display screen for a long time. The size of the pupil of the human eye depends on the ambient light brightness on the back of the display device, and there is a certain correspondence between the ambient light brightness on the back of the display device and the screen brightness of the display device. Therefore, the two can be adjusted to make the user's eyes more comfortable.

[0121] Specifically, the dimming accessory is located on the back of the display device. The dimming accessory includes an ambient light brightness sensing module, and the acquisition surface of the ambient light brightness sensing module faces away from the display surface of the display device, and is used to acquire the ambient brightness on the back of the display device. Since there is information interaction between the dimming accessory and the display device, when the environment needs to be adjusted by the screen dimming method, the ambient light brightness sensing module of the dimming accessory acquires the ambient light brightness, and then the dimming accessory sends the ambient light brightness on the back of the display device acquired by the ambient light brightness sensing module to the display device, so that the display device adjusts the screen brightness according to the ambient light brightness. If after adjusting the screen brightness of the display device to the lowest display brightness, the screen brightness still does not match the ambient light brightness on the back of the display device, that is, the ambient light brightness on the back of the display device is lower than the ambient light brightness matching the lowest display brightness, at this time, a more comfortable environment cannot be brought to the user, and the ambient light brightness on the back of the display device needs to be adjusted. Since the dimming accessory further includes a light emitting module, and the light emitting surface of the light emitting module faces away from the display surface of the display device, the back environment of the display device can be supplemented with light through the light emitting module. For example, when the display device adjusts the screen brightness to the lowest display brightness, and the ambient light brightness on the back of the display device is lower than the ambient light brightness matching the lowest display brightness, the display device sends an ambient light brightness adjustment instruction to the dimming accessory. The dimming accessory receives the ambient light brightness adjustment instruction sent by the display device, and controls the light emitting module to emit light to supplement light to the back of the display device, so as to adjust the ambient light brightness on the back of the display device. By increasing the ambient light brightness, the ambient light brightness of the display device is made more matched with the screen brightness of the display device, and the comfort of the user's eyes is improved.

[0122] Based on the above screen dimming method, an embodiment of the present disclosure further provides a screen dimming device. Figure 8 It is a structural block diagram of another screen dimming device provided by an embodiment of the present disclosure. Refer to Figure 8 The device includes: an ambient light brightness sending module 51 and a light emitting driving module 52.

[0123] The ambient light luminance sending module 51 is configured to send the ambient light luminance sensed by the ambient light luminance sensing module on the back of the display device to the display device, so that the display device adjusts the screen luminance according to the ambient light luminance. The light-emitting driving module 52 is configured to receive the ambient light luminance adjustment instruction sent by the display device and control the light-emitting module to emit light, so as to adjust the ambient light luminance on the back of the display device. Wherein, a dimming accessory is arranged on the back of the display device, and the dimming accessory includes an ambient light luminance sensing module and a light-emitting module; the acquisition surface of the ambient light luminance sensing module and the light-emitting surface of the light-emitting module face away from the display surface of the display device; the ambient light luminance adjustment instruction is sent when the display device adjusts the screen luminance to the lowest display luminance and the ambient light luminance on the back of the display device is lower than the ambient light luminance matching the lowest display luminance.

[0124] The present disclosure also provides a dimming accessory. Figure 9 FIG. 5 is a front view of a dimming accessory provided by an embodiment of the present disclosure. Figure 10 FIG. 6 is a side view of a dimming accessory provided by an embodiment of the present disclosure. Figure 11 FIG. 9 is a schematic structural view of a housing provided by an embodiment of the present disclosure. Figure 12 FIG. 11 is another schematic structural view of a housing provided by an embodiment of the present disclosure. Figure 13 FIG. 13 is a schematic structural view of a circuit board provided by an embodiment of the present disclosure, which can be obtained by cutting open the dimming accessory. Figures 11 - 13 , referring to Figures 9 - 13 , and in combination with Figure 4 shown in FIG. 19, the dimming accessory 6 is configured to be arranged on the back of the display device; the dimming accessory 6 includes an ambient light luminance sensing module 61 and a light-emitting module 62; the acquisition surface of the ambient light luminance sensing module 61 and the light-emitting surface of the light-emitting module 62 face away from the display surface of the display device.

[0125] The ambient light luminance sensing module 61 is configured to sense the ambient light luminance on the back of the display device, so that the display device adjusts the screen luminance of the display device according to the ambient light luminance on the back of the display device.

[0126] The dimming accessory 6 is further configured to control the light-emitting module 62 to emit light based on the ambient light luminance adjustment instruction, so as to adjust the ambient light luminance on the back of the display device.

[0127] Wherein, the ambient light luminance adjustment instruction is sent when the display device adjusts the screen luminance to the lowest display luminance and the ambient light luminance on the back of the display device is lower than the ambient light luminance matching the lowest display luminance.

[0128] Exemplarily, the dimming accessory 6 is arranged on the back of the display device and is independent of the display device before being arranged on the back of the display device. The dimming accessory 6 includes an ambient light luminance sensing module 61 and a light-emitting module 62, for example Figure 9, the dimming accessory 6 includes an ambient light luminance sensing module 61 and six light-emitting modules. Among them, the ambient light luminance sensing module 61 has a collection surface 611. The collection surface should be in contact with the ambient light for sensing. Therefore, the collection surface of the ambient light luminance sensing module 61 faces away from the display surface of the display device, so as to be in direct contact with the ambient environment on the back of the display device, sense the ambient light luminance on the back of the display device, and then the dimming accessory 6 sends the ambient light luminance collected by the ambient light luminance sensing module 61 to the display device, so that the display device adjusts the screen luminance of the display device according to the ambient light luminance on the back of the display device.

[0129] The light-emitting module 62 has a light-emitting surface 621, and light is emitted out through the light-emitting surface. Thus, the light-emitting surface should face away from the display surface of the display device, which can be understood as facing the ambient environment on the back of the display device. Based on the ambient light luminance on the back of the display device sent by the dimming accessory 6, the display device adjusts the screen luminance to the lowest display luminance, but the screen luminance still does not match the ambient light luminance on the back of the display device, that is, the ambient light luminance on the back of the display device is lower than the ambient light luminance corresponding to the lowest display luminance. At this time, a more comfortable environment cannot be brought to the user, and the display device will send an ambient light luminance adjustment instruction to the dimming accessory 6 to control the dimming accessory 6 to supplement light to the back of the display device. Then the dimming accessory 6 will control the light-emitting module 62 to emit light to adjust the ambient light luminance on the back of the display device.

[0130] Optionally, the dimming accessory 6 includes a housing 60. The housing 60 includes a top wall 601, a side wall 602, and a bottom surface 603. Figure 11 and Figure 12 is a view of the housing 60 cut open. A cavity is formed inside the housing 60 for placing the circuit board 70 of the dimming accessory 6 (which can be referred to Figure 13 ). The ambient light luminance sensing module 61 and the light-emitting module 62 are both arranged on the circuit board 70. A plurality of grooves are also provided on the housing 60, and the positions of the ambient light luminance sensing module 61 and the light-emitting module 62 on the circuit board 70 correspond to the grooves, so that the ambient light luminance sensing module 61 can sense the ambient light luminance and the light-emitting module 62 can supplement light.

[0131] The circuit board 70 is used to provide a driving circuit, a control circuit and a bearing platform for the ambient light luminance sensing module 61 and the light-emitting module 62 near the ground, and also has a plurality of modules with different functions, so that the dimming accessory 6 can operate normally, which will be described in detail below.

[0132] The housing 60 is preferably made of plastic and formed by an injection molding process. The housing 60 can be attached to the back of the display device by detachable means such as snap-fastening, bonding or adsorption. The shape of the dimming accessory 6 provided in the embodiment of the present disclosure is circular. In other application scenarios, the shape of the dimming accessory 6 can also be rectangular or other different shapes, and no specific limitation is made thereto.

[0133] Optionally, multiple light-emitting modules 62 are symmetrically arranged on the circuit board 70 about the left and right. Refer to Figure 13 , six light-emitting modules 62 are provided, which are respectively arranged in different areas of the dimming accessory 6, such as symmetrically arranged on the left and right sides of the main body of the dimming accessory 6, so as to make the supplementary light effect more uniform. Among them, the number of the light-emitting modules 62 is not limited, and can be one or multiple.

[0134] In some embodiments, continue to refer to Figure 13 , the dimming accessory 6 further includes a power module 63, and the power module 63 is used to supply power to the ambient light luminance sensing module 61 and the light-emitting module 62.

[0135] Exemplarily, the dimming accessory 6 further includes a power module 63, and the power module 63 can be arranged on the circuit board to supply power to the ambient light luminance sensing module 61 and the light-emitting module 62, so as to sense the ambient light luminance on the back of the display device and supplement the light on the back of the display device.

[0136] Optionally, the circuit board is annular, with a hollow area in the middle, and the power module is arranged in the hollow area. Since the dimming accessory provided by the embodiments of the present disclosure is circular, the shape of the circuit board can also match it, which is convenient for being arranged in the shell of the dimming accessory. And when the circuit board is arranged in an annular shape, there will be a hollow area in the middle. Arranging the power module, such as a battery, in the hollow area can save space and make full use of the existing space for structural design. After the power module is arranged in the middle hollow area, this area will bulge. Due to the bulge in the middle area, the whole dimming accessory presents a symmetric structure, and the product is more beautiful.

[0137] Optionally, continue to refer to Figure 13 , a charging interface 631 is arranged on the circuit board 70. In the embodiments of the present disclosure, when the power of the power module 63 is insufficient, the power module 63 can also be charged through the charging interface 631 to ensure that the dimming accessory 6 can work normally.

[0138] Optionally, the ambient light luminance sensing module 61 is arranged above the main body of the dimming accessory 6, and the charging interface 631 is arranged in the lower area of the main body of the dimming accessory 6. For example, when the display device is a mobile phone, arranging the ambient light luminance sensing module 61 in the upper area can avoid blocking the ambient light luminance sensing module 61 when using the mobile phone. If the ambient light luminance sensing module 61 is blocked, it will affect the accuracy of ambient light luminance sensing. In addition, the charging interface of the display device is usually located below. Arranging the charging interface 631 of the dimming accessory 6 in the lower area is more conducive to connecting the display device and the dimming accessory 6 through a wired connection structure, and avoiding too long wiring harnesses, causing inconvenience.

[0139] In some embodiments, a communication module is further included, and the dimming accessory is communicatively connected to the display device through the communication module.

[0140] Information interaction can be carried out between the display device and the dimming accessory, so as to sense the ambient light brightness on the back of the display device and supplement light to the back environment of the display device. Therefore, a communication module is also included in the dimming accessory. The communication module can also be arranged on the circuit board. The dimming accessory is communicatively connected to the display device through the communication module to realize information interaction.

[0141] The communication module can be various different types of wireless communication modules such as a Bluetooth communication module and a WiFi communication module. The display device and the dimming accessory are connected by wireless communication, which simplifies the overall structure, saves wiring harnesses, does not require frequent plugging and unplugging of data cables, avoids the situation of messy wires, and is more convenient for users' daily use.

[0142] In some embodiments, a wireless power receiving module is further included. The wireless power receiving module is used to obtain the electric energy transmitted by the wireless power transmitting module of the display device in a contactless manner and supply power to the ambient light brightness sensing module and the light emitting module.

[0143] The dimming accessory further includes a wireless power receiving module. When the dimming accessory is in contact with the back of the display device, for example, attached to the back of the display device, and the display device has a wireless power transmitting module, the dimming accessory can be charged without being connected to the display device through a wire harness. Specifically, the wireless power receiving module of the dimming accessory can obtain the electric energy transmitted by the wireless power emitting module of the display device in a contactless manner for charging. Furthermore, the wireless power receiving module of the dimming accessory can also supply power to the ambient light brightness sensing module and the light emitting module. The use of wire harnesses is reduced, and there is no need for frequent plugging and unplugging of data cables, avoiding the situation of messy wires.

[0144] In some embodiments, the dimming accessory further includes a wake-up module and a control module. The ambient light brightness sensing module, the light emitting module, and the wake-up module are all electrically connected to the control module; the wake-up module is used to send a wake-up signal instruction to the control module so that the control module controls the ambient light brightness sensing module to obtain the ambient light brightness on the back of the display device.

[0145] Among them, the wake-up module includes a gyroscope circuit, and the control module includes a control chip or a control circuit. When the wake-up module senses the movement of the display device, it sends a wake-up signal instruction to the control module. After receiving the wake-up signal instruction, since the control module is electrically connected to the ambient light brightness sensing module, the control module will control the ambient light brightness sensing module to obtain the ambient light brightness on the back of the display device. If the wake-up module does not sense the movement of the display device, it will not send a wake-up signal instruction to the control module. Therefore, the ambient light brightness sensing module will not start to sense, saving overall power consumption.

[0146] Optionally, since the control module is electrically connected to the light-emitting module, the control module can also control the light-emitting module to perform supplementary lighting.

[0147] In some embodiments, the dimming accessory further includes a magnetic attraction structure, and the dimming accessory is adsorbed to the back of the display device through the magnetic attraction structure.

[0148] Since the dimming accessory and the display device are independent of each other, when using the dimming accessory to execute the screen condition method, it is first necessary to set the dimming accessory on the back of the display device. For example, the magnetic attraction method can be used to combine the two. Therefore, the dimming accessory further includes a magnetic attraction structure. When there is a metal structure on the back of the display device, the dimming structure is adsorbed to the back of the display device through the magnetic attraction structure, and the combination is completed. When the user is not satisfied with the current attachment position, it can be directly removed and re-adsorbed. Or when the user needs to replace and use other display devices, the dimming accessory can be removed from the display device that is no longer used and adsorbed to the currently used display device. Setting the magnetic attraction structure facilitates the user to attach or remove the dimming accessory at any time in different application scenarios, which can be recycled and is more convenient.

[0149] In some embodiments, Figure 14 is a schematic structural diagram of a magnetic attraction plate provided by an embodiment of the present disclosure. Refer to Figure 14 and in combination with Figure 11 , the magnetic attraction structure 65 includes a magnet 651 and a magnetic attraction plate 652; the magnet 651 includes a magnetic substance; the magnetic attraction plate 652 can be attached to the back of the display device through an adhesive layer; the magnet is adsorbed to the back of the display device through the magnetic attraction plate.

[0150] Exemplarily, the magnetic attraction structure 65 includes a magnet 651 containing a magnetic substance. The magnet 651 is disposed in the housing 60 of the dimming accessory 6, so the dimming accessory 6 can be adsorbed to a structure made of a metal material through the internal magnet 651. When using the dimming accessory 6, it is necessary to set the dimming accessory 6 on the back of the display device. However, in some cases, the back of the display device is not a structure made of a metal material and cannot be combined with the magnet 651 inside the dimming accessory 6, resulting in the inability to apply the dimming accessory 6. To avoid the above situation, the magnetic attraction structure 65 provided by the embodiment of the present disclosure further includes a magnetic attraction plate 652. The magnetic attraction plate 652 is made of a metal material, such as an iron sheet structure, and can be adsorbed to the magnet 651. Therefore, the magnetic attraction plate 652 can be attached to the back of the display device through an adhesive layer, so that the magnet 651 in the dimming accessory 6 can be adsorbed to the back of the display device through the magnetic attraction plate 652.

[0151] Optionally, the housing 60 includes a plurality of magnets 651, for example Figure 11Eight magnets 651 are provided in the middle, and each magnet 651 is arranged around the edge of the housing. Among them, a plurality of grooves are provided inside the housing 60, and the magnets 651 are embedded inside the grooves. The housing 60 includes a top wall 601 and a bottom surface 603, and the magnets 651 are arranged on the top wall 601 and / or the bottom surface 603. The embodiments of the present disclosure do not limit this and can be designed according to the space. Arranging the magnets evenly around the edge of the housing can improve the adsorption effect, enabling each area of the dimming accessory 6 to be adsorbed, avoiding the situation where there is no magnet in a certain area and the adsorption force is poor, which affects the adsorption effect, and can save costs.

[0152] In some embodiments, continue to refer to Figure 14 , the magnetic attraction plate 652 is a non-closed ring.

[0153] Considering that a display device usually has a wireless charging function, the principle of wireless charging technology is mainly based on the electromagnetic induction principle. When an electric current flows through the transmitting coil, a magnetic field will be generated, and the receiving coil generates an electric current by inducing this magnetic field, thereby realizing the wireless transmission of electrical energy. If the magnetic attraction plate 652 is a closed ring, when the mobile phone is wirelessly charged, the magnetic attraction plate 652 will absorb electromagnetic waves to generate an electric current, causing a heating phenomenon. Therefore, in the embodiments of the present disclosure, the magnetic attraction plate 652 is set as a non-closed ring to avoid the above situation.

[0154] In some embodiments, Figure 15 is a side schematic view of a wired connection structure provided by an embodiment of the present disclosure, Figure 16 is a front schematic view of a wired connection structure provided by an embodiment of the present disclosure. Refer to Figure 15 and Figure 16 , and also includes a wired connection structure 64. The dimming accessory is electrically connected to the display device through the wired connection structure 64 and is used for data interaction with the display device and / or obtaining electrical energy provided by the display device.

[0155] Exemplarily, the dimming accessory in the embodiments of the present disclosure has a wired connection structure 64, and the wired connection structure 64 includes a first end 641 and a second end 642. Among them, the first end 641 of the wired connection structure 64 is electrically connected to the dimming accessory, and the second end 642 is electrically connected to the display device, thereby realizing the electrical connection between the dimming accessory and the display device. Based on this wired connection structure 64, data interaction between the dimming accessory and the display device can be realized. In some embodiments, the dimming accessory can also obtain electrical energy provided by the display device through the wired connection structure 64. In some embodiments, based on this wired connection structure 64, both data interaction between the two can be satisfied, and the dimming accessory can obtain electrical energy provided by the display device through the wired connection structure 64.

[0156] An embodiment of the present disclosure also provides a dimming system, which includes a display device and a dimming accessory. The dimming accessory is configured to be disposed on the back of the display device; the dimming accessory includes an ambient light brightness sensing module and a light emitting module.

[0157] The dimming accessory is configured to send the ambient light brightness on the back of the display device collected by the ambient light brightness sensing module to the display device, and the display device adjusts the screen brightness according to the ambient light brightness.

[0158] The display device is configured to adjust the screen brightness to the lowest display brightness, and when the ambient light brightness on the back of the display device is lower than the ambient light brightness corresponding to the lowest display brightness, send an ambient light brightness adjustment instruction to the dimming accessory; the dimming accessory controls the light emitting module to emit light based on the ambient light brightness adjustment instruction, so as to adjust the ambient light brightness on the back of the display device.

[0159] In the dimming system provided by the embodiment of the present disclosure, it includes a display device and a dimming accessory, and the dimming accessory is configured to be disposed on the back of the display device. When a user uses the display device, the light emitted by the screen of the display device will shine on the user's face and enter the human eye. For example, if the ambient light brightness on the back of the display device obtained is relatively dim, at this time the user's pupils are relatively large. If the screen brightness of the display device is relatively bright, it will cause a relatively large light flux to enter the human eye. In this way, it is very easy to cause visual fatigue after watching the display screen for a long time, affecting the user's visual health. Since the size of the human eye's pupils depends on the ambient light brightness on the back of the display device, and there is a certain correspondence between the ambient light brightness on the back of the display device and the screen brightness of the display device, the problem of the user's uncomfortable eye use in a relatively dim ambient light environment can be solved by adjusting the screen brightness of the display device and the ambient brightness on the back of the display device.

[0160] Specifically, the dimming accessory includes an ambient light brightness sensing module and a light emitting module. The ambient light brightness sensing module can collect the ambient light brightness on the back of the display device and send it to the display device, and the display device adjusts the screen brightness according to the ambient light brightness. Then the display device judges the ambient light brightness. If the screen brightness is adjusted to the lowest display brightness, and the ambient light brightness on the back of the display device is still lower than the ambient light brightness corresponding to the lowest display brightness, an ambient light brightness adjustment instruction is sent to the dimming accessory. After receiving this instruction, the dimming accessory controls the light emitting module to emit light to adjust the ambient light brightness on the back of the display device, so that the ambient light brightness on the back of the display device increases, improving the eye use environment, enhancing the user's eye use comfort when using the display device, avoiding visual fatigue, and playing a role in protecting eyesight.
