[0002] In daily life, 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.

Detailed implementation manners

[0027] In order to more clearly understand the above objects, features, and advantages of the present disclosure, the following will further describe the solutions of the present disclosure. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0028] A number of specific details are set forth in the following description to facilitate a full understanding of 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.

[0029] 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, mainly due to the relatively dim ambient light brightness on the back of the display device, the diameter of the user's pupils is relatively large, so that more light enters the eyes, resulting in discomfort for the user's eyes. But the area where the screen of the display device is located only occupies 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.

[0030] To solve the above problems, an embodiment of the present disclosure provides a screen dimming method applicable to a dimming accessory. This method can be executed by a screen dimming device provided by an embodiment of the present disclosure, and the screen dimming device can be implemented in a software and / or hardware manner. The screen dimming device can be integrated in the dimming accessory, and this method can be executed by a module or chip with control or processing functions in the dimming accessory.

[0031] Figure 1 A schematic structural diagram of a dimming accessory provided by an embodiment of the present disclosure is provided for a display device. Figure 2 A front view schematic diagram of a dimming accessory provided by an embodiment of the present disclosure. Figure 3 A side view schematic diagram of a dimming accessory provided by an embodiment of the present disclosure. Figure 4 A schematic structural diagram of a housing provided by an embodiment of the present disclosure. Figure 5 Another schematic structural diagram of a housing provided by an embodiment of the present disclosure. Figure 6 A schematic structural diagram of a circuit board provided by an embodiment of the present disclosure. Refer to Figures 1 - 6 , the dimming accessory 1 is disposed on the back of the display device; the dimming accessory 1 includes an ambient light brightness sensing module 11 and a light emitting module 12; the collection surface of the ambient light brightness sensing module 11 and the light emitting surface of the light emitting module 12 are both oriented away from the display surface of the display device.

[0032] Among them, the dimming accessory 1 is disposed on the back of the display device and is independent of the display device before being disposed on the back of the display device. The dimming accessory 1 includes an ambient light brightness sensing module 11 and a light emitting module 12, as Figure 2As shown in the figure, the dimming accessory 1 includes an ambient light luminance sensing module 11 and six light emitting modules 12. The ambient light luminance sensing module 11 has a collection surface, and the collection surface of the ambient light luminance sensing module 11 faces away from the display surface of the display device so as to be in direct contact with the environment on the back of the display device, and sense the ambient light luminance on the back of the display device. The light emitting module 12 has a light emitting surface, and light is emitted outwards through the light emitting surface. Therefore, the light emitting surface should face away from the display surface of the display device, which can be understood as facing the environment on the back of the display device.

[0033] Optionally, the dimming accessory 1 includes a housing 10, and the housing 10 includes a top wall 101, a side wall 102 and a bottom surface 103. Figure 4 and Figure 5 is a view of the housing 10 cut open. A cavity is formed inside the housing 10 for placing the circuit board 20 of the dimming accessory 1 (reference can be made to Figure 6 ). The ambient light luminance sensing module 11 and the light emitting module 12 are both arranged on the circuit board 20. A plurality of grooves are also arranged on the housing 10, and the positions of the ambient light luminance sensing module 11 and the light emitting module 12 on the circuit board 20 correspond to the grooves, so that the ambient light luminance sensing module 11 can sense the ambient light luminance and the light emitting module 12 can perform supplementary lighting.

[0034] The circuit board 20 is used to provide a driving circuit, a control circuit and a bearing platform for the ambient light luminance sensing module 11 and the light emitting module 12 near the ground, and is also provided with a plurality of modules with different functions, so that the dimming accessory 1 can operate normally, which will be described in detail below.

[0035] The housing 10 is preferably made of plastic and formed by an injection molding process. The housing 10 can be attached to the back of the display device by detachable means such as snap fit, bonding or adsorption. The shape of the dimming accessory 1 provided in the embodiment of the present disclosure is circular. In other application scenarios, the shape of the dimming accessory 1 can also be rectangular or other different shapes, which is not specifically limited herein.

[0036] Optionally, a plurality of light emitting modules 12 are symmetrically arranged on the left and right of the circuit board 20. Referring to Figure 2 , six light emitting modules 12 are provided, which are respectively arranged in different areas of the dimming accessory 1, for example, symmetrically arranged on the left and right sides of the main body of the dimming accessory 1, so as to make the supplementary lighting effect more uniform. Among them, the number of the light emitting modules 12 is not limited, and can be one or multiple.

[0037] Based on the above dimming accessory, the embodiment of the present disclosure provides a schematic flow chart of a screen dimming method. Figure 7 This is a schematic flow chart of a screen dimming method provided by the embodiment of the present disclosure. Referring to Figure 7 , the screen dimming method includes S110 - S130: S110. Obtain the ambient light brightness on the back of the display device through the ambient light brightness sensing module.

[0038] Since during the user's use of the display device, the area where the ambient light is located on the back of the display device occupies the main part of the user's viewing angle, the ambient light brightness on the back of the display device 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. Also, because the pupil sizes are different, there are differences in the light flux entering the human eye, and the degree of influence of light on the human eye is different, resulting in different levels of comfort perceived by the human eye. Therefore, 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. The dimming accessory includes an ambient light brightness sensing module, and the ambient light brightness sensing module has a collection surface. The collection surface of the ambient light brightness sensing module faces away from the display surface of the display device. Thus, the ambient light brightness on the back of the display device can be obtained through the ambient light brightness sensing module.

[0039] S120. Send a screen brightness adjustment instruction to the display device according to the ambient light brightness on the back of the display device, so that the display device adjusts the screen brightness according to the screen brightness adjustment instruction.

[0040] When the user uses the 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 enlarge to adapt to this darker environment. At this time, 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 and affect the visual health of the user when watching the display screen for a long time.

[0041] Since 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 corresponding relationship between the ambient light brightness on the back of the display device and the screen brightness of the display device, the dimming accessory sends a screen brightness adjustment instruction to the display device according to the obtained ambient light brightness on the back of the display device, so that the display device adjusts the screen brightness according to the screen brightness adjustment instruction, turns down the screen brightness, and changes the light flux entering the human eye.

[0042] S130. Obtain the screen brightness of the display device. Based on the fact that the screen brightness of the display device has been 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 matching the lowest display brightness, control the light-emitting module to emit light to adjust the ambient light brightness on the back of the display device.

[0043] Specifically, there is a corresponding relationship between the ambient light brightness on the back of the display device and the screen brightness of the display device. When this corresponding relationship is met, users will feel more comfortable when using the display device. Therefore, the dimming accessory obtains the adjusted screen brightness of the display device. When the screen brightness has been adjusted to the lowest display brightness, it compares the relationship between the ambient light brightness on the back of the display device and the ambient light brightness that matches the lowest display brightness of the display device. If the ambient light brightness on the back of the display device is still lower than the ambient light brightness that matches the lowest display brightness, it can be understood that after adjusting the screen brightness of the display device, the screen brightness 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 further reduced. At this time, it cannot bring a more comfortable environment to the user, and the ambient brightness on the back of the display device can be adjusted to achieve this.

[0044] 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 light-emitting module can be used to supplement light to the environment on the back of the display device. The dimming accessory controls the light-emitting module to emit light and supplement light to the environment on 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 users' eyes.

[0045] It should be noted that the embodiments of the present disclosure do not limit how to supplement light to the environment on the back of the display device. Light-emitting elements, such as light-emitting diodes, can be set, or the original structure of the display device can be used. Specific optional implementation manners can be referred to in the following text and will not be elaborated here.

[0046] The embodiments of the present disclosure obtain the ambient light brightness on the back of the display device through the ambient light brightness sensing module and send a screen brightness adjustment instruction to the display device, so that the display device adjusts the screen brightness according to the screen brightness adjustment instruction. If 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 when the screen brightness of the display device is adjusted to the lowest display brightness, resulting in discomfort for the user's eyes, it is necessary to control the light-emitting module to emit light and supplement light to the environment on the back of the display device to adjust the ambient light brightness on the back of the display device and increase the ambient light brightness on the back of the display device. Thereby, the user's eye environment is improved, the eye comfort of the user when using the display device is enhanced, visual fatigue is avoided, and the effect of protecting eyesight is achieved.

[0047] In the embodiments of the present disclosure, a screen dimming method is executed by a dimming accessory. In the current application scenario, a user is using a display device, and the dimming accessory is disposed on the back of the display device and can interact with the display device. Therefore, the screen dimming method can be executed by the dimming accessory. When using the dimming accessory to execute the screen dimming method, data processing and arithmetic judgment are performed by the dimming accessory, without occupying the computing resources of the display device, and the normal computing use of the display device such as a mobile phone will not be affected.

[0048] In some embodiments, based on that the screen brightness of the display device has been 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 matching the lowest display brightness, controlling the light-emitting module to emit light to adjust the ambient light brightness on the back of the display device includes: Based on that the screen brightness of the display device has been 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 matching the lowest display brightness, controlling the light-emitting brightness of the light-emitting module 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.

[0049] 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 a more comfortable environment for the user to use the display device cannot be brought, and the experience and comfort are poor. At this time, the adjustment can be continued by adjusting the ambient light on the back of the display device.

[0050] When controlling the light-emitting module to emit light to supplement light to the environment on the back of the display device, the light-emitting brightness of the light-emitting module can be controlled according to the ambient light brightness on the back of the display device to supplement light to the environment on the back of the display device, increase the ambient light brightness, reduce the pupil size of the user, and the light flux entering the pupil will also decrease, thereby improving the eye use comfort. There is a matching relationship between the ambient light brightness on the back of the display device and the screen brightness. Since the current screen is at the lowest display brightness, the light-emitting brightness of the light-emitting module is controlled with the ambient light brightness matching the lowest display brightness of the screen as the target reference 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 matches the lowest display brightness of the screen.

[0051] 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 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 is essentially adjusting 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 is essentially adjusting 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 luminous brightness during supplementary lighting can be large; if the gap is small, the luminous brightness during supplementary lighting is correspondingly small. Thus, the luminous brightness of the light-emitting module of the dimming accessory is controlled according to the ambient light brightness on the back of the display device to make the supplementary lighting effect better.

[0052] In addition, there are various ways to control the luminous brightness of the light-emitting module. For example, the luminous brightness of the light-emitting module can be adjusted by controlling the power of the light-emitting module. When the power of the light-emitting module is different, the brightness of the light generated by the light-emitting module is different. The greater the power, the greater the brightness of the light generated by the light-emitting module, that is, the greater the luminous brightness of the supplementary lighting. The smaller the power, the smaller the brightness of the light generated by the light-emitting module, that is, the smaller the luminous brightness of the supplementary lighting. Therefore, the luminous brightness of the light-emitting module can be adjusted by adjusting the power of the light-emitting module, and then the ambient light brightness on the back of the display device can be changed.

[0053] Optionally, the luminous brightness of the light-emitting module is controlled by controlling the number of light-emitting modules (the luminous brightness of the light-emitting module mentioned here refers to the sum of the luminous brightness of all light-emitting modules). Among them, the number of light-emitting modules can be set according to actual needs. One light-emitting module can be set, and the generated light brightness is smaller, saving power consumption; multiple light-emitting modules can also be set, and the generated light brightness is larger, distributed in different areas, and the supplementary lighting for the back of the display device is more uniform, improving the supplementary lighting effect. It can be specifically set according to actual needs.

[0054] It should be noted that the embodiments of the present disclosure do not specifically limit how to control the luminous brightness of the light-emitting module. The above are only some feasible embodiments for illustrative purposes. The embodiments of the present disclosure do not limit the specific ways of adjusting the matching relationship between the ambient light brightness and the screen brightness. The above embodiments are only for illustrative purposes.

[0055] In some embodiments, the ambient light brightness sensing module includes a photosensitive element; Obtaining the ambient light brightness on the back of the display device through the ambient light brightness sensing module includes: collecting the ambient light brightness on the back of the display device through the photosensitive element.

[0056] Exemplarily, the ambient light luminance sensing module is used to obtain the ambient light luminance on the back of the display device, and the specific way to obtain the ambient light luminance depends on the type of the ambient light luminance sensing module. For example, the ambient light luminance sensing module includes a photosensitive element, and the sensing element can be an ambient light sensor, etc. The photosensitive element can directly sense the surrounding light luminance, that is, directly collect the ambient light luminance on the back of the display device through the photosensitive element, without a large amount of calculation, avoiding occupying the computing resources of the dimming accessory.

[0057] In some embodiments, the ambient light luminance sensing module includes an image acquisition module; Obtaining the ambient light luminance on the back of the display device through the ambient light luminance sensing module includes: Obtaining the ambient image on the back of the display device through the image acquisition module.

[0058] Determining the ambient light luminance on the back of the display device according to the ambient image on the back of the display device.

[0059] In addition to the photosensitive element mentioned in the above embodiments, the ambient light luminance sensing module may further include an image acquisition module. For example, a camera is provided on the ambient light luminance sensing module of the dimming accessory. The image acquisition module is usually used to obtain image information, so the image acquisition module can be used to obtain the ambient image on the back of the display device. When the image acquisition module is in different ambient light luminances, the corresponding image gray levels of the obtained ambient images are different. According to the ambient image on the back of the display device, the corresponding image gray level can be recognized, and then the ambient light luminance on the back of the display device can be determined according to the image gray level.

[0060] It should be noted that the specific structure of the ambient light luminance sensing module in the embodiments of the present disclosure is not limited and can be set according to actual needs.

[0061] In some embodiments, sending a screen brightness adjustment instruction to the display device according to the ambient light luminance on the back of the display device includes: Determining the screen brightness adjustment instruction corresponding to the ambient light luminance on the back of the display device according to the corresponding relationship between the ambient light luminance on the back of the display device and the screen brightness of the display device.

[0062] Exemplarily, as mentioned above, there is a certain corresponding relationship between the ambient light luminance and the screen brightness. When the corresponding relationship is satisfied, the user is most comfortable using the display device in this case. Among them, the corresponding relationship between the ambient light luminance on the back of the display device and the screen brightness of the display device can be preset. For example, if the corresponding relationship is implemented by an algorithm, the corresponding algorithm between the ambient light luminance on the back of the display device and the screen brightness of the display device can be stored in advance. For example, it can be stored in the display device, or in the dimming accessory, or in the cloud, and the corresponding relationship can be obtained from the cloud.

[0063] Specifically, in the above steps, the ambient light brightness on the back of the display device has been obtained through the ambient light brightness sensing module. For example, the currently detected ambient light brightness is A. Based on the stored correspondence between the ambient light brightness on the back of the display device and the screen brightness of the display device, according to the algorithm, the screen brightness of the display device corresponding to the ambient light brightness of A can be calculated as B. Therefore, the screen brightness adjustment instruction corresponding to the ambient light brightness on the back of the display device is the instruction to adjust the screen brightness to B.

[0064] In some cases, the correspondence between the ambient light brightness on the back of the display device and the screen brightness of the display device is implemented through a corresponding table. Similarly, the corresponding table can be stored in advance. After detecting the ambient light brightness, the screen brightness of the display device corresponding to the current ambient light brightness can be found based on the corresponding table, and then the screen brightness adjustment instruction corresponding to the ambient light brightness on the back of the display device can be determined.

[0065] In some embodiments, based on the fact that the screen brightness of the display device has been 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 matching the lowest display brightness, controlling the light emission brightness of the light-emitting module 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 includes: Based on the fact that the screen brightness of the display device has been 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 matching the lowest display brightness, determining the light emission brightness of the light-emitting module according to the difference between the ambient light brightness on the back of the display device and the ambient light brightness matching the lowest display brightness, so that after the light-emitting module emits light, the ambient light brightness on the back of the display device is adjusted to the ambient light brightness matching the lowest display brightness.

[0066] Since there is a certain correspondence between the ambient light brightness of the display device and the screen brightness of the display device, when the correspondence is satisfied, the user is most comfortable using the display device in this case. If the screen brightness of the display device is adjusted to the lowest display brightness and the screen brightness still does not match the ambient light brightness on the back of the display device, the ambient light brightness on the back of the display device is lower than the ambient light brightness matching the lowest display brightness. For example, the lowest display brightness of the display device screen is A1, the ambient light brightness of the display device it matches is B1, and the currently obtained ambient light brightness by the ambient light brightness sensing module of the dimming accessory is B0, and the current ambient light brightness B0 is less than the ambient light brightness B1 matching the lowest display brightness. At this time, it cannot bring a more comfortable environment to the user, and it is necessary to control the light-emitting module to emit light to supplement the light for the back environment of the display device to adjust the ambient light brightness on the back of the display device.

[0067] Specifically, when controlling the light-emitting module to supplement light to the environment on the back of the display device, the luminous brightness of the light-emitting module is related to the difference between the ambient light brightness B0 on the back of the display device and the ambient light brightness B1 that matches the lowest display brightness A1. After determining the luminous brightness of the light-emitting module according to the difference between the ambient light brightness B0 on the back of the display device and the ambient light brightness B1 that matches the lowest display brightness A1, control the light-emitting module to emit light so that the ambient light brightness B0 on the back of the display device is adjusted to the ambient light brightness B1 that matches the lowest display brightness A1. Among them, the larger the difference between the ambient light brightness B0 and the ambient light brightness B1 that matches the lowest display brightness A1, the lower the ambient light brightness on the back of the display device, and the greater the brightness of the supplementary light; while the smaller the difference, the relatively lower the ambient light brightness on the back of the display device, and the smaller the brightness of the supplementary light. Therefore, after determining the luminous brightness of the light-emitting module, control the light-emitting module to emit light and supplement light 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.

[0068] In some embodiments, before controlling the light-emitting module to emit light, it further includes: Obtain the status information of the display device and determine that the screen of the display device is in the display working state.

[0069] The purpose of controlling the light-emitting module to emit light in the embodiments of the present disclosure is to supplement light to the environment on the back of the display device, improve the user's eye use environment, make the environment for the user to use the display device more comfortable, and avoid eye fatigue of the user. Therefore, the prerequisite for controlling the light-emitting module to emit light is that the user is using the display device, and then there will be problems such as the ambient light brightness on the back of the display device not matching the screen brightness of the display device, resulting in discomfort and fatigue of the user's eyes.

[0070] Therefore, it is necessary to determine whether the screen of the display device is in the display working state before controlling the light-emitting module to emit light. 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, and there is no need to control the light-emitting module to emit light or supplement light to the environment 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, and the screen dimming method provided by the embodiments of the present disclosure can be executed. If there is a need, control the light-emitting module to emit light and supplement light to the environment on the back of the display device. This can not only save power but also provide a more comfortable environment for the user when using the display device.

[0071] The embodiments of the present disclosure further provide a screen dimming device, which is integrated or loaded in a dimming accessory. Figure 8 For the structural block diagram of a screen dimming device provided by the embodiments of the present disclosure, see Figure 8, applicable to a dimming accessory, the screen dimming device includes: an ambient light brightness acquisition module 21, a screen brightness adjustment module 22, and a light emission driving module 23.

[0072] The ambient light brightness acquisition module 21 is configured to acquire the ambient light brightness on the back of the display device through an ambient light brightness sensing module. The screen brightness adjustment module 22 is configured to send a screen brightness adjustment instruction to the display device according to the ambient light brightness on the back of the display device, so that the display device adjusts the screen brightness according to the screen brightness adjustment instruction. The light emission driving module 23 is configured to acquire the screen brightness of the display device, and based on that the screen brightness of the display device has been 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 matching the lowest display brightness, control the light emitting module to emit light to adjust the ambient light brightness on the back of the display device. Wherein, the dimming accessory is arranged on the back of the display device; the dimming accessory includes an ambient light brightness sensing module and a light emitting module; the acquisition 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.

[0073] The embodiment of the present disclosure also provides a dimming accessory. Figure 9 Is a schematic structural diagram of a dimming accessory provided by an embodiment of the present disclosure, refer to Figure 9 , including a processor and a memory. Among them, 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 embodiment is implemented. Specifically, as Figure 9 shown, it can be set to include 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. The bus system 304 includes, in addition to a data bus, a power bus, a control bus, and a status signal bus. However, for the sake of clear illustration, in Figure 9 all kinds of buses are labeled as the bus system 304.

[0074] 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 embodiment of the present disclosure, the processor 302 executes the steps of each embodiment of the screen dimming method provided by the embodiment of the present disclosure by calling the programs or instructions stored in the memory 301.

[0075] The method provided by 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. During implementation, 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 the form of software.

[0076] The steps of the method provided by the embodiments of the present disclosure can be directly embodied as being executed and completed by a hardware decoding processor, or can be executed and completed 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.

[0077] In some embodiments, with continued reference to Figure 6 , the dimming accessory 1 further includes a power module 13, and the power module 13 is used to supply power to the ambient light luminance sensing module 11 and the light emitting module 12.

[0078] Exemplarily, the dimming accessory 1 further includes a power module 13, and the power module 13 can be arranged on the circuit board 20 to supply power to the ambient light luminance sensing module 11 and the light emitting module 12, so that the dimming accessory 1 can sense the ambient light luminance on the back of the display device and supplement light for the environment on the back of the display device.

[0079] Optionally, the circuit board 20 is circular with a hollow area in the middle, and the power module 13 is arranged in the hollow area. Since the dimming accessory 1 provided by the embodiments of the present disclosure is circular, the shape of the circuit board 20 can also match it, which is convenient for being arranged in the housing of the dimming accessory 1. And when the circuit board 20 is arranged in a circular ring shape and the power module 13 is arranged in the hollow area, for example, the power module 13 is a battery, it 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, and due to the bulge in the middle area, the whole dimming accessory presents a symmetrical structure, making the product more beautiful.

[0080] Optionally, with continued reference to Figure 6, a charging interface 131 is provided on the circuit board 20. In the embodiments of the present disclosure, when the power of the power module 13 is insufficient, the power module 13 can also be charged through the charging interface 131 to ensure that the dimming accessory 1 can work properly.

[0081] Optionally, the ambient light luminance sensing module 11 is provided above the main body of the dimming accessory 1, and the charging interface 131 is provided in the lower area of the main body of the dimming accessory 1. For example, when the display device is a mobile phone, setting the ambient light luminance sensing module 11 in the upper area can avoid blocking the ambient light luminance sensing module 11 when using the mobile phone. If the ambient light luminance sensing module 11 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. Setting the charging interface 131 of the dimming accessory 1 in the lower area is more conducive to connecting the display device and the dimming accessory 1 through a wired connection structure, avoiding too long wire harnesses and causing inconvenience.

[0082] In some embodiments, a communication module is further included, and the dimming accessory is communicatively connected to the display device through the communication module.

[0083] Information interaction can be carried out between the display device and the dimming accessory, so as to realize the sensing of the ambient light luminance on the back of the display device and the supplementary light to the back environment of the display device. Therefore, a communication module is further 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.

[0084] 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 wire harnesses, does not require frequent plugging and unplugging of data cables, avoids the situation of many wires in a mess, and is more convenient for users' daily use.

[0085] In some embodiments, a wireless power receiving module is further included. The wireless power receiving module is used to non-contactedly obtain the electric energy transmitted by the wireless power transmitting module of the display device and supply power to the ambient light luminance sensing module and the light emitting module.

[0086] The dimming accessory further includes a wireless power receiving module. When the dimming accessory is in contact with the back of the display device, such as being 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 non-contactedly obtain the electric energy transmitted by the wireless power emitting module of the display device for charging. Furthermore, the wireless power receiving module of the dimming accessory can also supply power to the ambient light luminance sensing module and the light emitting module. The use of wire harnesses is reduced, and there is no need to frequently plug and unplug data cables, avoiding the situation of many wires in a mess.

[0087] Optionally, 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 configured 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.

[0088] 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 the overall power consumption.

[0089] Optionally, since the control module is electrically connected to the light-emitting module, the control module can also control the light-emitting module to emit light.

[0090] 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.

[0091] Since the dimming accessory and the display device are independent of each other, when using the dimming accessory to execute the screen condition method, the dimming accessory needs to be set on the back of the display device. For example, a 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 in use and adsorbed to the currently used display device. The setting of 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.

[0092] In some embodiments, Figure 10 is a schematic structural diagram of a magnetic attraction plate provided by an embodiment of the present disclosure. Refer to Figure 10 and in combination with Figure 4 , the magnetic attraction structure includes a magnet 151 and a magnetic attraction plate 152; the magnet 151 includes a magnetic substance; the magnetic attraction plate 152 can be attached to the back of the display device through an adhesive layer; the magnet 151 is adsorbed to the back of the display device through the magnetic attraction plate 152.

[0093] Exemplarily, the magnetic attraction structure includes a magnet 151 containing magnetic substances. The magnet 151 is disposed inside the housing 10 of the dimming accessory 1, so that the dimming accessory 1 can be attracted to a structure made of a metal material through the internal magnet 151. When using the dimming accessory 1, it is necessary to set the dimming accessory 1 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 attracted to the magnet 151 inside the dimming accessory 1, resulting in the inability to apply the dimming accessory 1. To avoid the above situation, the magnetic attraction structure provided by the embodiments of the present disclosure further includes a magnetic attraction plate 152. The magnetic attraction plate 152 is made of a metal material, such as an iron sheet structure, and can be attracted to the magnet 151. Therefore, the magnetic attraction plate 152 can be attached to the back of the display device through an adhesive layer, so that the magnet 151 in the dimming accessory 1 can be attracted to the back of the display device through the magnetic attraction plate 152.

[0094] Optionally, the housing 10 includes a plurality of magnets 151. For example, Figure 4 eight magnets 151 are provided, and each magnet 151 is disposed around the edge of the housing 10. Among them, a plurality of grooves are provided inside the housing 10, and the magnets 151 are embedded inside the grooves. Refer to Figure 4 and Figure 5 , the housing 10 includes a top wall 101 and a bottom surface 103, and the magnet 151 is disposed on the top wall 101. The embodiments of the present disclosure do not limit this, and can be designed according to the space. Disposing the magnets evenly around the edge of the housing can improve the adsorption effect, so that each area of the dimming accessory can be adsorbed, avoiding the situation that there is no magnet in a certain area and the adsorption force is poor, which affects the adsorption effect, and can save costs.

[0095] In some embodiments, continue to refer to Figure 10 , the magnetic attraction plate 152 is a non-closed ring.

[0096] Some display devices have 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 electric energy. If the magnetic attraction plate 152 is a closed ring, when the mobile phone is wirelessly charged, the magnetic attraction plate 152 will absorb electromagnetic waves to generate an electric current, causing a heating phenomenon. Therefore, the embodiments of the present disclosure set the magnetic attraction plate 152 as a non-closed ring to avoid the magnetic attraction plate generating an electric current and heating.

[0097] In some embodiments, Figure 11 is a side schematic view of a wired connection structure provided by the embodiments of the present disclosure, Figure 12 is a front schematic view of a wired connection structure provided by the embodiments of the present disclosure. Refer to Figure 11 and Figure 12, further including a wired connection structure 14. The dimming accessory is electrically connected to the display device through the wired connection structure 14, and is used for data interaction with the display device and / or obtaining electric energy provided by the display device.

[0098] Exemplarily, the dimming accessory in the embodiments of the present disclosure has a wired connection structure 14, and the wired connection structure 14 includes a first end 141 and a second end 142. Wherein, the first end 141 of the wired connection structure 14 is electrically connected to the dimming accessory, and the second end 142 is electrically connected to the display device, so as to realize the electrical connection between the dimming accessory and the display device. Based on this wired connection structure 14, data interaction between the dimming accessory and the display device can be realized. In some embodiments, the dimming accessory can also obtain the electric energy provided by the display device through the wired connection structure 14. In some embodiments, based on this wired connection structure 14, both data interaction between the two can be satisfied, and the dimming accessory can obtain the electric energy provided by the display device through the wired connection structure 14.

[0099] The embodiments of the present disclosure further provide a screen dimming method, which is 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 a software and / or hardware manner. The screen dimming device can be integrated in the display device, and the screen dimming device can be, for example, a control chip of the display device. The embodiments of the present disclosure do not limit the type of the display device. For example, the display device can be a mobile phone, a tablet computer, etc. Figure 13 It is a schematic flowchart of another screen dimming method provided by the embodiments of the present disclosure. Refer to Figure 13 , the screen dimming method includes S410 - S420: S410, obtain a screen brightness adjustment instruction, and adjust the screen brightness according to the screen brightness adjustment instruction.

[0100] S420, send the screen brightness of the display device to the dimming accessory, so that the dimming accessory controls the light-emitting module to emit light based on that the screen brightness of the display device has been 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 matching the lowest display brightness, so as to adjust the ambient light brightness on the back of the display device.

[0101] Wherein, the dimming accessory is arranged on the back of the display device; 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 screen brightness adjustment instruction is sent by the dimming accessory to the display device according to the ambient light brightness on the back of the display device.

[0102] When a user uses a display device, the light emitted by the screen of the display device will shine on 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. 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. 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 corresponding relationship 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.

[0103] Exemplarily, a dimming accessory is provided on the back of the display device. The dimming accessory includes an ambient light brightness sensing module. The acquisition surface of the ambient light brightness sensing module faces away from the display surface of the display device and is used to obtain the ambient light brightness on the back of the display device. There is data interaction between the dimming accessory and the display device. When it is necessary to adjust through a screen dimming method, the display device will obtain a screen brightness adjustment instruction and adjust the screen brightness according to the screen brightness adjustment instruction to reduce the screen brightness of the display device. Among them, the screen brightness adjustment instruction is sent by the dimming accessory to the display device according to the ambient light brightness on the back of the display device.

[0104] The display device sends the current screen brightness of the display device to the dimming accessory. If, after adjusting the screen brightness of the display device to the lowest display brightness, the current 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 matched by the lowest display brightness, then at this time, a more comfortable environment cannot be brought to the user, and it is necessary for the dimming accessory to control the light-emitting module to emit light to adjust the ambient light brightness on the back of the display device. The light-emitting surface of the light-emitting module faces away from the display surface of the display device. Therefore, the ambient light on the back of the display device can be supplemented by controlling the light-emitting module to emit light.

[0105] For example, the display device will send the screen brightness of the display device to the dimming accessory. 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 by the lowest display brightness, the dimming accessory controls the light-emitting module to emit light to supplement the ambient light on 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.

[0106] Based on the above screen dimming method, an embodiment of the present disclosure further provides a screen dimming device. Figure 14 For the structural block diagram of another screen dimming device provided by an embodiment of the present disclosure, refer to Figure 14 , the device includes: a screen brightness adjustment instruction acquisition module 51 and a screen brightness sending module 52.

[0107] The screen brightness adjustment instruction acquisition module 51 is configured to acquire a screen brightness adjustment instruction and adjust the screen brightness according to the screen brightness adjustment instruction. The screen brightness sending module 52 is configured to send the screen brightness of the display device to the dimming accessory, so that the dimming accessory controls the light-emitting module to emit light based on that the screen brightness of the display device has been 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 matching the lowest display brightness, so as to adjust the ambient light brightness on the back of the display device. Wherein, the dimming accessory is arranged on the back of the display device; the dimming accessory includes an ambient light brightness sensing module and a light-emitting module; the acquisition 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 screen brightness adjustment instruction is sent by the dimming accessory to the display device according to the ambient light brightness on the back of the display device.

[0108] The embodiments of the present disclosure further provide a display device, Figure 15 which is a schematic structural diagram of a display device provided by the embodiments of the present disclosure, including a processing unit and a storage unit. Among them, instructions are stored in the storage unit for the processing unit to execute. When the processing unit executes the instructions, the above-mentioned screen dimming method is implemented.

[0109] Specifically, as Figure 15 shown, it can be set to include at least one processing unit 602, at least one storage unit 601, and at least one communication unit 603. Each component in the display device is coupled together through a bus 604. The communication unit 603 is used for data transmission with external devices. It can be understood that the bus 604 is used to realize the connection and communication between these components. In addition to the data bus, the bus 604 also includes a power bus, a control bus, and a status signal bus. However, for the sake of clear illustration, in Figure 15 all kinds of buses are labeled as the bus 604.

[0110] It can be understood that the storage unit 601 in this embodiment can be a volatile memory or a non-volatile memory, or can include both a volatile memory and a non-volatile memory. In some embodiments, the storage unit 601 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 processing unit 602 executes the steps of the various embodiments of the screen dimming method provided by the embodiments of the present disclosure by calling the programs or instructions stored in the storage unit 601.

[0111] The method provided by the embodiments of the present disclosure can be applied to or implemented by the processing unit 602. The processing unit 602 can be an integrated circuit chip with signal processing capabilities. During implementation, the steps of the above method can be completed by the integrated logic circuit of the hardware in the processing unit 602 or instructions in software form. The above processing unit 602 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 any conventional processor, etc.

[0112] The steps of the method provided by the embodiments of the present disclosure can be directly embodied as being executed and completed by a hardware decoding processor, or by a combination of hardware and software units in the decoding processor. The software units can be located in a mature storage medium in the art such as random access memory, flash memory, read-only memory, programmable read-only memory, or electrically erasable programmable memory, registers, etc. This storage medium is located in the storage unit 601, and the processing unit 602 reads the information in the storage unit 601 and combines its hardware to complete the steps of the method. The embodiments of the present disclosure also provide a dimming system, including a display device and a dimming accessory. The dimming accessory is used 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.

[0113] The dimming accessory generates a screen brightness adjustment instruction according to the ambient light brightness sensed by the ambient light brightness sensing module on the back of the display device, and sends it to the display device, so that the display device adjusts the screen brightness according to the screen brightness adjustment instruction.

[0114] The display device is used to send the screen brightness to the dimming accessory, so that the dimming accessory controls the light emitting module to emit light based on the screen brightness of the display device having been 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.

[0115] If the ambient light brightness on the back of the current display device is relatively dim, in order to adapt to this dim environment, the pupils of the human eyes will dilate. 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 eyes. In this way, it is easy to cause visual fatigue and affect the visual health of users when watching the display screen for a long time. Since the size of the pupils of the human eyes depends on the ambient light brightness on the back of the display device, there is a certain corresponding relationship between the ambient light brightness on the back of the display device and the screen brightness of the display device. Therefore, the problem of uncomfortable eye use by users in a 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.

[0116] Specifically, in the dimming system provided in the embodiments of the present disclosure, it includes a display device and a dimming accessory. The dimming accessory is used to be arranged on the back of the display device. The dimming accessory includes an ambient light brightness sensing module and a light emitting module. The ambient sensing module is used to sense the ambient light brightness on the back of the display device. Since there is a corresponding relationship between the ambient light brightness on the back of the display device and the screen brightness of the display device, the dimming accessory sends a screen brightness adjustment instruction to the display device according to the obtained ambient light brightness on the back of the display device, so that the display device adjusts the screen brightness according to the screen brightness adjustment instruction, turns down the screen brightness, and changes the light flux entering the human eyes.

[0117] After receiving the screen brightness adjustment instruction sent by the dimming accessory, the display device adjusts its own screen brightness and sends the screen brightness to the dimming accessory. The dimming accessory makes a judgment. If after adjusting the screen brightness 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, the dimming accessory controls the light emitting module to emit light to adjust the ambient light brightness on the back of the display device to increase the ambient light brightness on the back of the display device, improve the eye use environment, enhance the eye use comfort of users when using the display device, avoid visual fatigue, and play a role in protecting eyesight.
