[0033] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0034] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0035] Figure 2 The structure diagram of an air supply device for a display screen provided by an embodiment of the present disclosure is shown in FIG. Figure 2 As shown, the air supply device includes: an air supply member 10, an air inlet 20 and an air guide member 30 arranged on the back of the display screen;

[0036] Optionally, the air blown by the air supply member 10 is blown toward the display screen 100 through the air inlet 20, that is, the air blown by the air supply member 10 enters the interior of the display screen 100 through the air inlet 20. Optionally, the air supply member 10 can reuse a cooling fan of the electronic device where the display screen is located, or a separate air supply fan can be provided.

[0037] The air guide member 30 is used to guide the air blown out by the air supply member 10 to the surface of the display screen 100 for cleaning when the display screen is in a cleaning mode.

[0038] Optionally, the air guide member 30 is also used to synchronously guide the wind blown out by the air supply member 10 to the rear cavity of the display screen 100 for heat dissipation when the display screen is in a cleaning mode.

[0039] In the disclosed embodiment, the air supply device blows the air from the air supply device toward the surface of the display screen in the cleaning mode, without relying on specific cleaning tools. This can solve the problem that the display screen cannot be cleaned manually due to the special location of the display screen. The dust accumulated on the surface of the display screen can be cleaned by the wind, thereby ensuring the display effect and quality of the display screen. Furthermore, by using the air blown out of the air supply device to clean the dust accumulated on the surface of the display screen, the risk of scratching the surface of the display screen when wiping the display screen with tools can be avoided.

[0040] Figure 3 The structure diagram of an air supply device for a display screen provided by an embodiment of the present disclosure is shown in FIG. Figure 3 As shown, based on the above embodiment, optionally, the air guide member 30 includes an air guide switch 31 and an air guide slot 32 .

[0041] Optionally, the controller in the display screen is used to control the opening and closing of the air guide switch 31.

[0042] Optionally, when the wind guide switch 31 is turned on, a portion of the wind entering the air inlet 20 is blown toward the surface of the display screen 100 for cleaning under the action of the wind guide groove 32, while another portion of the wind entering the air inlet 20 is blown toward the back cavity of the display screen 100 for heat dissipation.

[0043] Optionally, when the wind guide switch 31 is turned off, all the wind entering the air inlet 20 is blown toward the rear cavity of the display screen 100 for heat dissipation.

[0044] Optionally, the air guide groove 32 includes three surfaces, wherein the three surfaces form a groove 320, and the surface of the display screen 100 is at least partially located in the groove 320. Optionally, the air guide groove 32 includes a first surface 321, a second surface 322, and a third surface 323, wherein the three surfaces form the groove 320. Optionally, the groove 320 may be a regular groove or an irregular groove, which is not limited in the present disclosure.

[0045] Optionally, the first surface of the air guide groove 32 is connected to the first side edge 101 of the back side of the display screen 100 , and the air inlet 20 is arranged on the back side of the display screen 100 and is located near the first side edge 101 .

[0046] Optionally, when the air guide switch 31 is closed, it is perpendicular to the first surface 321 of the air guide groove 32 and is arranged at the first side 101 , or at the outer edge 21 of the air inlet 20 parallel to the first side 101 .

[0047] Optionally, when the air guide switch 31 is turned on, it is no longer perpendicular to the first surface 321 of the air guide groove 32 . For example, it can be parallel to the first surface 321 of the air guide groove 32 , or have a certain angle with the first surface 321 of the air guide groove 32 .

[0048] In some embodiments, the opening angle of the air guide switch 31 can be controlled based on the length of the cleaning interval. For example, if the cleaning interval is long, the air guide switch 31 can be fully opened so that a large amount of wind from the air inlet enters the air guide groove and blows toward the surface of the display screen, so that the surface of the display screen is cleaned relatively cleanly. For another example, if the cleaning interval is short, the air guide switch 31 can be opened at a smaller angle so that a small amount of wind from the air inlet enters the air guide groove to clean the surface of the display screen. In this case, a large amount of wind from the air inlet can be blown toward the back cavity of the display screen, which can take into account the heat dissipation effect on the display screen.

[0049] In some embodiments, the opening angle of the air guide switch 31 can be controlled based on the cleaning control instruction.

[0050] In some embodiments, the opening angle of the air guide switch 31 can be controlled based on the dirtiness of the display screen. Optionally, the dirtiness of the display screen can be detected by image technology or sensors.

[0051] In the disclosed embodiment, when the wind guide switch is turned on, the display screen can be cleaned and cooled at the same time, thereby solving the problem that the display screen cannot be cleaned manually due to the particularity of the setting position. The dust accumulated on the surface of the display screen can be cleaned by wind, so as to ensure the display effect and quality of the display screen. Moreover, by cleaning the dust accumulated on the surface of the display screen by wind, the risk of scratching the surface of the display screen by wiping the display screen with tools can be avoided. Furthermore, when the wind guide switch is turned off, the wind blows almost entirely to the back cavity of the display screen, so as to achieve concentrated wind force to cool the display screen and enhance the cooling effect.

[0052] Figure 4 The structure diagram of an air supply device for a display screen provided by an embodiment of the present disclosure is shown in FIG. Figure 4 As shown, based on the above embodiment, optionally, the air guide member 30 includes an air guide switch group and an air guide slot 32 , wherein the air guide switch group includes a first air guide switch 311 and a second air guide switch 312 .

[0053] Optionally, the controller of the display screen is used to control the opening and closing of the first wind guide switch 311 and the second wind guide switch 312.

[0054] Optionally, when the first wind guide switch 311 is turned off and the second wind guide switch 312 is turned on, the wind entering the air inlet 20 is directed to the surface of the display screen 100 for cleaning under the action of the wind guide groove 32 .

[0055] Optionally, when the first wind guide switch 311 is turned on and the second wind guide switch 312 is turned off, the wind entering the air inlet 20 is all blown toward the rear cavity of the display screen 100 for heat dissipation.

[0056] Optionally, the first wind guide switch 311 and the second wind guide switch 312 are both perpendicular to the first surface 321 of the air guide groove 32 when they are closed, wherein the second wind guide switch 312 is arranged at the first side 101, or at the outer edge 21 of the air inlet 20 parallel to the first side 101, and the first wind guide switch 311 is arranged at the inner edge 22 of the air inlet parallel to the first side 101.

[0057] In the disclosed embodiment, when the first wind guide switch is turned off and the second wind guide switch is turned on, the wind entering the air inlet is blown toward the surface of the display screen for cleaning under the action of the wind guide groove. This can solve the problem that the display screen cannot be cleaned manually due to the particularity of its setting position, and the dust accumulated on the surface of the display screen can be cleaned by wind, so that the surface of the display screen can be cleaned, thereby ensuring the display effect and quality of the display screen. Moreover, by cleaning the dust accumulated on the surface of the display screen by wind, the risk of scratching the surface of the display screen by wiping the display screen with tools can be avoided. Furthermore, when the first wind guide switch is turned on and the second wind guide switch is turned off, all the wind entering the air inlet is blown toward the back cavity of the display screen for heat dissipation, so that concentrated wind force is used to dissipate heat for the display screen, thereby enhancing the heat dissipation effect.

[0058] Figure 5 The structure diagram of an air supply device for a display screen provided by an embodiment of the present disclosure is shown in FIG. Figure 5 As shown, the air supply device includes: an air supply member (not shown in the figure), an air inlet and an air guide member arranged on the back of the display screen, and the air guide member forms an irregular groove. The air guide switch SW1 and the air guide switch SW2 in the air guide member 30 can make the wind entering the air inlet blow to different places along wind direction 1 and wind direction 2 in different states. When the air guide switch SW1 is turned on and the air guide switch SW2 is turned off, the wind entering the air inlet enters the back cavity of the display screen along wind direction 1 for heat dissipation. When the air guide switch SW1 is turned off and the air guide switch SW2 is turned on, the wind entering the air inlet enters the surface of the display screen along wind direction 2 for cleaning. Optionally, when the user finds that dust or foreign matter has affected the display of the picture, the fan control switch can be actively turned on to guide the wind to the screen surface through the built-in air guide to clean the surface dust / foreign matter, or the system software can be set to clean each power-on initialization stage. This function is similar to the active defog function of the front window, so that the fan can be used for surface cleaning while satisfying the cooling function. Figure 5a The figure shows the air flow path of the air supply member on the back of the display screen. The air blown by the air supply member can enter through the air inlet, and in the cleaning mode, the air can be directed to the surface of the display screen through the air guide member. In the heat dissipation mode, the air can be blown out from the inside of the display screen through the internal circulation and then through the air outlet, thereby removing the heat inside the display screen.

[0059] Figure 6 The following is a flow chart of a method for cleaning a display screen provided by an embodiment of the present disclosure. Figure 6 As shown, the method for cleaning the display screen includes but is not limited to the steps of:

[0060] S601, control the air supply device of the display screen to turn on.

[0061] S601, controlling the air supply device to enter a cleaning mode, so as to send the air blown out by the air supply device to the surface of the display screen for cleaning.

[0062] In the embodiment of the present application, the display screen corresponds to an air supply device, such as Figures 2 to 5 As shown, no further description is given here.

[0063] In some embodiments, the display screen may be a display screen of an electronic device, and the electronic device may include, but is not limited to, at least one of: Internet of Things devices, cars with communication functions, smart cars, tablet computers (Pad), computers with wireless transceiver functions, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminal devices in unmanned aerial vehicles (UAV), wireless terminal devices in industrial control, wireless terminal devices in self-driving, wireless terminal devices in remote medical surgery, wireless terminal devices in smart grids, wireless terminal devices in transportation safety, wireless terminal devices in smart cities, and wireless terminal devices in smart homes, but is not limited to these.

[0064] In some embodiments, the display screen can be understood as a display screen that is set at a specific position of the device and cannot be directly cleaned manually by the user. For example, the display screen can be a panoramic display or HUD on a vehicle. These display screens can project vehicle information (such as vehicle speed, navigation instructions, fuel consumption, etc.) into the driver's front field of view, usually projected on the front windshield to reduce the driver's line of sight movement and improve driving safety. These display screens may be set inside the junction of the IP and the front windshield, which is difficult for users to reach with their hands or tools. Although this position can be used to prevent the entry of large particles, small particles (such as dust) are very easy to be adsorbed by static electricity. After long-term use, it is easy to produce dust accumulation, which may affect the display quality when it is serious.

[0065] In the embodiment of the present application, the air supply device can be turned on when the display screen is working. In order to clean the dust accumulated on the surface of the display screen, the air supply device can be controlled to enter the cleaning mode to clean the display screen through the air supply device.

[0066] In some embodiments, the air supply device can be controlled to enter the cleaning mode according to the set cleaning cycle to clean the dust accumulated on the surface of the display screen. For example, when the set cleaning cycle is reached at the current moment, the air supply device can be controlled to enter the cleaning mode.

[0067] Optionally, the timing starts from the end time of the last cleaning of the display screen surface, and in response to the timing reaching the set cleaning cycle, the air supply device is controlled to enter the cleaning mode. It is understandable that in response to the timing not setting the cleaning cycle, the air supply device is controlled to enter the heat dissipation mode.

[0068] In some embodiments, the air supply device can be controlled to enter the cleaning mode based on the user control instruction to clean the dust accumulated on the surface of the display screen. For example, the user control instruction is a cleaning mode start instruction, which can control the air supply device to enter the cleaning mode.

[0069] Optionally, a user control instruction is received, and in response to the user control instruction being a cleaning mode, the air supply device is controlled to enter the cleaning mode. It is understandable that in response to the user control instruction being a cooling mode, the air supply device is controlled to enter the cooling mode.

[0070] In some embodiments, the user control instruction may be a contact control instruction. For example, the user may generate the user control instruction by clicking a button or icon on the screen.

[0071] In some embodiments, the user control instruction may be a contactless control instruction, for example, the user may generate the user control instruction by voice or gesture, etc. Optionally, the user's voice information with keywords is collected by a microphone, the voice information is further recognized, and the user control instruction is generated according to the recognition result, for example, "turn on cleaning mode".

[0072] Optionally, the user's gesture is captured by an image capture device, and based on a pre-established mapping relationship between gestures and modes, a target mode corresponding to the user's current gesture is determined, thereby generating a user control instruction.

[0073] In some embodiments, the air supply device may be controlled to enter the cleaning mode when the display screen is powered on for the first time each time it is used. Optionally, the power-on signal of the display screen is detected, and the time interval between the power-on signal of the current time and the power-on signal of the previous time is determined. In response to the time interval being greater than the set time interval, it can be determined that the display screen is powered on for the first time, and the air supply device may be controlled to enter the cleaning mode. It is understandable that in response to the time interval being less than or equal to the set time interval, the air supply device is controlled to enter the heat dissipation mode.

[0074] In the embodiment of the present application, after the air supply device enters the cleaning mode, the air blown out by the air supply device can be directed to the surface of the display screen. That is to say, there can be an air guide between the air supply device and the surface of the display screen, and the air blown out by the air supply device is blown to the surface of the display screen through the air guide. Without relying on specific cleaning tools, the dust accumulated on the surface of the display screen can be cleaned, and the surface of the display screen can be cleaned, thereby solving the problem that the display screen cannot be manually cleaned due to the particularity of the setting position, and the display effect and quality of the display screen can be guaranteed. Furthermore, by cleaning the dust accumulated on the surface of the display screen with the air blown out by the air supply device, the risk of scratching the surface of the display screen when wiping the display screen with tools can be avoided.

[0075] Figure 7 A schematic diagram of another method for cleaning a display screen provided by an embodiment of the present disclosure. Figure 7 As shown, the method for cleaning the display screen includes but is not limited to the following steps:

[0076] S701, control the air supply device of the display screen to turn on.

[0077] S702, controlling the air supply device to enter a cleaning mode, so as to send the air blown out by the air supply device to the surface of the display screen for cleaning.

[0078] In some embodiments, the wind guide switch is controlled to be turned on to guide a portion of the wind blown out by the air supply device to the surface of the display screen for cleaning; and / or another portion of the wind blown out by the air supply device is guided to the back cavity of the display screen for heat dissipation, such as Figure 3 shown.

[0079] In some embodiments, the first wind guide switch is controlled to be closed and the second wind guide switch is controlled to be opened so as to guide the wind blown out by the air supply device to the surface of the display screen for cleaning. Figure 4 shown.

[0080] Optionally, the interval time when the air supply device last entered the cleaning mode is determined. If the interval time is greater than the set interval, the dust accumulated on the surface of the display screen is relatively large. In order to ensure the cleaning effect, the first air guide switch can be turned off when the second air guide switch is turned on to increase the air volume entering the air guide slot, thereby improving the cleaning effect. If the interval time is less than or equal to the set value, the dust accumulated on the surface of the display screen is relatively small. When the second air guide switch is turned on, the second air guide switch can be kept turned on to take into account both heat dissipation and cleaning.

[0081] Optionally, the opening and closing of the first and second air guide switches can be controlled based on the user's cleaning needs, such as the cleaning intensity. For example, if deep cleaning is selected, in order to ensure the cleaning effect, the first air guide switch can be turned off while the second air guide switch is turned on, so as to increase the air volume blowing to the display surface, thereby improving the cleaning effect. For example, if daily cleaning is selected, the first air guide switch can be kept open while the second air guide channel is turned on, taking into account both heat dissipation and cleaning.

[0082] S703, determining the set working time of the cleaning mode.

[0083] In some embodiments, the set operating time of the cleaning mode may be determined based on a default configuration of the air supply device, and the set operating time of the cleaning mode may be determined from default configuration information.

[0084] In some embodiments, the set working time of the cleaning mode can be determined based on the user configuration operation of the air supply device.

[0085] S704, in response to the accumulated working time of the air supply device in the cleaning mode reaching the set working time, controlling the air supply device to enter the heat dissipation mode.

[0086] After the air supply device is controlled to enter the cleaning mode, the cumulative working time of the air supply device in the cleaning mode can be counted. Further, in response to the cumulative working time reaching the set working time of the cleaning mode, the air supply device is controlled to enter the temperature control mode. It is understandable that in response to the cumulative working time not reaching the set working time of the cleaning mode, the air supply device is controlled to continue to work in the cleaning mode.

[0087] Optionally, a timer is provided. After the air supply device is controlled to enter the cleaning mode, the cumulative working time of the air supply device in the cleaning mode can be counted by the timer. In response to the counted cumulative working time reaching the set working time of the cleaning mode, the air supply device is controlled to enter the heat dissipation mode.

[0088] It is understandable that whenever the air supply device exits the cleaning mode and enters the cooling mode, the accumulated working time of that time will be reset to zero, and the counting or timing will be restarted after the next entry into the cleaning mode.

[0089] In some embodiments, the wind guide switch is controlled to be closed so that all the wind blown out by the air supply device is directed to the rear cavity of the display screen for heat dissipation. Figure 3 By turning off the air guide switch, the air volume entering the rear cavity of the display screen is increased, thereby improving the heat dissipation effect, preventing the display screen from overheating, and thus extending the life of the display screen.

[0090] In some embodiments, the first wind guide switch is controlled to be turned on and the second wind guide switch is controlled to be turned off, so that all the wind blown out by the air supply device is directed to the rear cavity of the display screen for heat dissipation. Figure 4 By turning off the second air guide switch, the air volume entering the rear cavity of the display screen is increased, thereby improving the heat dissipation effect, preventing the display screen from overheating, and thus extending the life of the display screen.

[0091] In the embodiment of the present application, the air supply device of the display screen can be controlled to enter the cleaning mode, and the air blown out by the air supply device in the cleaning mode is blown to the surface of the display screen, so that the dust accumulated on the surface of the display screen can be cleaned, and the surface of the display screen can be cleaned. Furthermore, after the cleaning is completed, the air supply device can be controlled to enter the temperature control mode, and the display screen can continue to be cooled to protect the display screen. In the embodiment of the present application, while ensuring the basic heat dissipation function of the air supply device, the surface of the display screen can also be cleaned, which can not only ensure the life of the display screen, but also improve the display quality.

[0092] Figure 8 A schematic diagram of another method for cleaning a display screen provided in an embodiment of the present application. Figure 8 As shown, the method for cleaning the display screen includes but is not limited to the steps of:

[0093] S801, determining whether the display screen is powered on for the first time.

[0094] If the display screen is powered on for the first time, execute step S802; if the display screen is not powered on for the first time, execute step S803.

[0095] S802, determining whether the default configuration of the display screen is power-on cleaning.

[0096] If the default configuration of the display screen is power-on cleaning, execute step S804; if the default configuration of the display screen is not power-on cleaning, execute step S803.

[0097] S803, determining whether a control instruction to start the cleaning mode is received from the user.

[0098] If a control instruction for starting the cleaning mode is received from the user, step S804 is executed; if a control instruction for starting the cleaning mode is not received from the user, step S805 is executed.

[0099] S804, enter the cleaning mode, control the first air guide switch to be turned off, and the second air guide switch to be turned on.

[0100] S805, entering the heat dissipation mode, controlling the first air guide switch to be turned on, and the second air guide switch to be turned off.

[0101] S806, determining whether the cleaning mode has reached the set working time.

[0102] If the accumulated working time of the cleaning mode reaches the set working time, execute step S805; if the accumulated working time of the cleaning mode does not reach the set working time, continue to execute step S804 until it reaches the set working time, and enter step S805.

[0103] In the embodiment of the present application, the air supply device of the display screen can be controlled to enter the cleaning mode, and the air blown out by the air supply device in the cleaning mode is blown to the surface of the display screen, so that the dust accumulated on the surface of the display screen can be cleaned, and the surface of the display screen can be cleaned. Furthermore, after the cleaning is completed, the air supply device can be controlled to enter the temperature control mode, and the display screen can continue to be cooled to protect the display screen.
