[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings of the embodiments of the present application.

[0028] It should be understood that some embodiments described herein are merely used to explain the technical solutions of the present application, and are not intended to limit the technical scope of the present application.

[0029] An electronic device provided by the embodiments of the present application, as shown in the figure, comprises: Figure 1A As shown in the figure, the electronic device comprises:

[0030] The display module 11 is configured to output an image to a first side of the display module.

[0031] Here, the first side of the display module is the side facing the user, that is, the first side of the display module can output an image to provide for the user to view. For example, in the case of the electronic device being a display, the display module can be a display screen (liquid crystal screen) of the display, and the side of the display screen for outputting an image is the first side of the display screen.

[0032] The detection module 12 is configured to emit a wireless detection signal and receive a returned wireless feedback signal. The detection module is arranged on a second side of the display module, and the first side and the second side are opposite sides of the display module.

[0033] As shown in the figure, the detection module 12 is arranged on the second side of the display module. Figure 1AAs shown, the detection module 12 is arranged on the second side of the display module. In the implementation process, the detection module can be a high-frequency radio (millimeter radar wave) module for transmitting and receiving wireless signals, wherein high frequency refers to a signal frequency between 30 GHz (gigahertz) and 300 GHz, and millimeter radar wave refers to a signal wavelength between 10 millimeters and 1 millimeter. Preferably, the transmission frequency can be set to 60 GHz, and the transmission frequency can also be dynamically adjusted according to actual conditions, such as 55 GHz to 65 GHz, so as to achieve different detection distances and improve the corresponding accuracy.

[0034] In the implementation process, the detection module can be provided with a transceiving antenna to realize the transmission of a wireless detection signal and the reception of a returned wireless feedback signal. Here, the number of transceiving antennas of the detection module is not limited, for example, the transceiving antenna can be set to single transmission and double reception, or the antenna can be set to double transmission and four reception, and the multiple receiving antennas can realize the complementary effect of receiving wireless feedback signals, effectively improving the detection accuracy. In the implementation process, the maximum detection distance can be determined by designing the line width, line length and / or wiring mode of the transceiving antenna.

[0035] Here, the detection direction of the wireless detection signal is not limited, and the detection direction of the wireless detection signal can be designed to include the first side of the display module, or the detection direction of the wireless detection signal can be designed to include all possible directions except the first side. For example, in the case where the detection direction of the wireless detection signal is designed to be the left side or the right side of the display module, the detection module can detect whether there is another user in the left side range or the right side range of the display module.

[0036] The processing module 13 is configured to process the wireless feedback signal, and control the switching of the display of the electronic device when the wireless feedback signal meets a first condition.

[0037] Here, the first condition includes that the target object parameter in the detection range of the detection module meets the condition. In the implementation process, the target object parameter includes at least one of the following: the number of users, the position of the user, and the orientation of the user. For example, in the case where the wireless detection signal is transmitted to the user's body and then reflected back to the wireless feedback signal, since the wireless feedback signal has different waveforms, the waveform can represent information such as the user's heartbeat, body movement or pulse. The processing module can identify the number of users within the preset distance in the detection direction of the detection module based on the user's heartbeat, body movement or pulse information, i.e., determine the position of the user and the orientation of the user.

[0038] In the embodiments of the present application, the display module is configured to output an image to a first side of the display module; the detection module is configured to emit a wireless detection signal and receive a wireless feedback signal returned; the detection module is arranged on a second side of the display module, the first side and the second side being opposite sides of the display module; and the processing module is configured to process the wireless feedback signal and control switching of the display of the electronic device when the wireless feedback signal meets a first condition. In this way, the display of the electronic device can be switched based on the wireless feedback signal received by the detection module to meet the needs of customers.

[0039] Figure 1B An architecture schematic diagram of an electronic device provided in the embodiments of the present application is shown in FIG. 1, which includes a display module 11, a master control chip (processing module) 13, a detection module 12, and an artificial intelligence and digital processing chip 41. The detection module 12 includes a millimeter radar wave transmitting and receiving module 1, a millimeter radar wave transmitting and receiving module 2, and a millimeter radar wave transmitting and receiving module 3. The processing module 13 is the master control chip in the figure. For example, the master control chip can be a Scalar of the display, which is used to process internal data of the display. In some embodiments, as shown in FIG. 2, the electronic device further includes an artificial intelligence sensor and a data processing chip 41 for processing the wireless feedback signal. Figure 1B Figure 1B

[0040] Figure 1C A use scenario schematic diagram of an electronic device provided in the embodiments of the present application is shown in FIG. 3, which includes a display module 11, a user 21 watching the display module, a 0-degree line 22, a 30-degree line 23, and a 45-degree line 24. Figure 1C

[0041] When the processing module determines that the wireless feedback signal represents that there is a second user in a preset angle range of observing the output image, the processing module can control switching of the display of the electronic device. For example, the processing module can detect the heart rate of the second user and the displacement change and / or speed change of the second user based on the wireless feedback signal, determine that there is a second user in a preset angle and distance range (1.5 meters or 2 meters) in the direction of the 30-degree line 23 or the 45-degree line 24, and automatically achieve a 30-degree or 45-degree range of the display module, that is, the output image of the display module cannot be seen outside the 30-degree or 45-degree viewing angle, while not affecting the use of the user 21 watching the output image. Alternatively, the processing module can also automatically realize the blurring of the screen, so as to remind the user 21 watching the output image that there is another user watching the output image.

[0042] ​​​In some embodiments, when the processing module determines that the wireless feedback signal represents that no user watches the output image, the display screen can enter a black screen mode, thereby achieving the effect of reducing power consumption.

[0043] In some embodiments, the electronic device can be a device with strong image generation capability, such as an all-in-one computer or a tablet computer. In other embodiments, the electronic device is a display device of a device with strong image generation capability, which further comprises a communication module for obtaining an image signal from an image output device, and the processing module is further configured to process the image signal. Wherein, the communication module can be a display interface of the display screen, and the display interface can refer to an interface connected with a graphics card of the image output device. Common display interfaces on graphics cards include at least one of the following: Digital Visual Interface (DVI) interface, High Definition Multimedia (HDMI) interface, Video Graphics Array (VGA) interface, Display Port interface, USB interface and Separate Video (S) terminal, etc.; the communication module can also refer to a network interface (including wireless and wired) of the display screen.

[0044] Here, the image signal obtained by the communication module is not the signal of the electronic device itself, that is, the communication module can first obtain the signal sent by other devices connected with the electronic device, and then analyze the signal to make the processing module restore the image that can be displayed on the display module.

[0045] In some embodiments, as shown in Figure 2A The display module 11 comprises:

[0046] The light-emitting assembly 112 has opposite third and fourth sides, and is configured to emit first light from the third side.

[0047] Here, the light-emitting assembly 11 can comprise a light guide plate and a light source as shown in Figure 2B Figure 2B The light guide plate and light source shown in the figure is a side-in backlight, and the design of the light source can arrange the lamp beads (light source) around the light guide plate.

[0048] In some embodiments, the light-emitting assembly can also be a direct backlight, that is, the lamp beads are arranged on the second side of the display module.

[0049] As shown in Figure 2B The light-emitting assembly 11 is configured to emit first light from the third side.

[0050] ​Display component 111 is at least partially disposed within the illumination range of the first light source, and is used to switch to a matching display state in response to an image signal. The first light source can emit a second light source from the first side through the display component, and the second light source is light that can be perceived as the image. The detection module is disposed on the fourth side of the light-emitting component. The emission direction of the first light source and the detection direction of the detection module satisfy the same condition.

[0051] In some embodiments, in order to detect the target object viewing the image output by the display module, the detection direction of the detection module can be the same as the emission direction of the first light, and the wireless detection signal can penetrate the LCD screen to achieve the detection effect.

[0052] During implementation, the back of the display screen uses a metal patch or iron backplate. Metal has a shielding effect on wireless detection signals. Since the detection module does not need to transmit wireless detection signals in the direction opposite to the emission direction of the first light, that is, there is no need to set up a transceiver antenna. Therefore, the design of placing the side of the detection module that does not need to transmit wireless detection signals close to the back of the display screen will not affect the detection effect.

[0053] Here, as Figure 2A The display component 111 shown is disposed on the third side of the light-emitting component and is at least partially disposed within the illumination range of the first light. Here, since the first light emitted from the third side of the light-emitting component is for illuminating the display component, the display component needs to be at least partially disposed within the illumination range of the first light so that at least part of the display component can be illuminated by the first light. Preferably, the entire display component can be disposed within the illumination range of the first light so that the entire display component can be illuminated by the first light.

[0054] Here, the image signal is used to switch the display state of the display component, so that the display component can display the required image according to the image signal.

[0055] The first light ray can emit a second light ray from the first side through the display component. The second light ray is the light ray that can be perceived as the image, that is, the second light ray is the light ray that can be perceived by the user viewing the display component.

[0056] like Figure 2A As shown, the detection module 12 can be set on the fourth side of the light-emitting component 112. In this way, the detection module 12 will not affect the light-emitting function of the light-emitting component 112. Since the wireless detection signal emitted by the detection module 12 can pass through the light-emitting component 112 and the display component 111, the detection module 12 can also realize the detection function.

[0057] In some embodiments, the exit direction of the first light and the detection direction of the detection module satisfy the same condition, i.e., the exit direction of the first light and the detection direction of the detection module can partially coincide, or completely coincide, preferably, the center line of the exit direction of the first light is parallel to or coincides with the center line of the detection direction of the detection module, so as to achieve the effect that the detection module can detect the existence of the target object watching the display screen from the detection direction of the detection module.

[0058] In some embodiments, as shown in FIG. 1, the fourth side of the light-emitting assembly 112, i.e., the second side of the display module 11. Figure 2A

[0059] In the embodiments of the present application, the display module comprises: a light-emitting assembly for emitting first light from the third side; and a display assembly at least partially disposed in the illumination range of the first light, for switching to a matched display state in response to an image signal. In this way, the light-emitting assembly in the display module can emit first light for providing light for the output image; and the display assembly in the display module can switch to a matched display state in response to an image signal, meeting the use requirements of the user.

[0060] In some embodiments, the display module further comprises: a light-reflecting assembly having opposite fifth and sixth sides, the fifth side being configured to reflect third light emitted from the fourth side of the light-emitting assembly to form part of the first light; wherein the detection module is at least partially disposed in the light-reflecting assembly; or disposed at the sixth side; wherein the position of the light-reflecting assembly corresponding to the detection module satisfies the penetration condition of the wireless detection signal and the wireless feedback signal.

[0061] As shown in FIG. 1, the light-reflecting assembly 113 has opposite fifth and sixth sides, and the fifth side is configured to reflect third light emitted from the fourth side of the light-emitting assembly 112 to form part of the first light. Figure 2C Figure 2B As shown in FIG. 1, the light-reflecting assembly 113 is disposed at the fourth side of the light-emitting assembly 112. Here, since the light emitted by the light-emitting assembly 112 includes not only the first light satisfying the same condition as the detection direction of the detection module 12, but also the third light emitted from the fourth side of the light-emitting assembly 112, the light-reflecting assembly 113 is needed to reflect the third light to form part of the first light. Here, the other part of the first light is emitted by the light-emitting assembly 112. The light-reflecting assembly 113 is disposed to facilitate improving the utilization rate of light and reducing energy consumption.

[0062] ​​In some embodiments, the detection module can be disposed within the reflective component. This can be achieved by providing at least one space on the reflective component to accommodate the detection module, and placing the detection module within that space. In this case, a light-reflecting material needs to be provided on the side of the detection module facing the light-emitting component to avoid affecting the light-emitting function of the reflective component.

[0063] In some embodiments, such as Figure 2C As shown, the detection module 12 can be positioned on the sixth side of the reflective component 113. The position of the reflective component corresponding to the detection module needs to meet the penetration conditions of the wireless detection signal and the wireless feedback signal. During implementation, the shape of part of the reflective component can be modified to meet these penetration conditions. For example, small holes can be provided on the reflective component, or the material of part of the reflective component can be thinned.

[0064] In some embodiments, such as Figure 2C As shown, the sixth side of the reflective component 113 is the second side of the display module 11.

[0065] In this embodiment, the display module further includes: a reflective component having opposite fifth and sixth sides, the fifth side being used to reflect the third light emitted from the fourth side of the light-emitting component to form a portion of the first light; the detection module is at least partially disposed within the reflective component; or, disposed on the sixth side; the position of the reflective component corresponding to the detection module satisfies the penetration conditions of the wireless detection signal and the wireless feedback signal. Thus, the reflective component can reflect the third light emitted from the fourth side of the light-emitting component to form a portion of the first light; the detection module can be partially disposed within the reflective component, or it can be disposed on the sixth side of the reflective component, and the position of the reflective component corresponding to the detection module satisfies the penetration conditions of the wireless detection signal and the wireless feedback signal, so as not to affect the operation of the detection module.

[0066] In some embodiments, the detection module has a seventh side, which is a side that transmits wireless detection signals and receives wireless feedback signals, wherein the seventh side is opposite to the fourth side; wherein at least a portion of the seventh side of the detection module is provided with a light-reflecting material to reflect the third light emitted from the fourth side of the light-emitting component to form a portion of the first light.

[0067] like Figure 2C As shown, the detection module 12 has a seventh side that transmits wireless detection signals and receives wireless feedback signals, and the seventh side is opposite to the fourth side of the light-emitting component 112.

[0068] In some embodiments, a penetrating material or a hollowed portion of the light-reflecting component (a small hole is formed on the light-reflecting component) can be arranged on the light-reflecting component to reduce the loss of the wireless detection signal emitted by the detection module passing through the light-reflecting component. In this way, the light-reflecting material can be arranged on at least part of the seventh side of the detection module 12, so that the light-reflecting material arranged on the detection module 12 can compensate for the light-reflecting function of the light-reflecting component, reflect the third light emitted from the fourth side of the light-emitting component 112 to form part of the first light. In some embodiments, the detection component can be made of black plastic, so that the hollowed portion of the light-reflecting component or the penetrating material corresponding to the detection component can cause the display screen to display a light shadow. Preferably, the light-reflecting material can be arranged on the hollowed portion of the light-reflecting component or the part of the detection component corresponding to the penetrating material. In this way, the light-reflecting function of the light-reflecting component is compensated, and the problem of the display screen displaying a shadow is also solved. For example, the light-reflecting material can be a white film or ink with high reflectivity.

[0069] In some embodiments, the seventh side of the detection module can be arranged with a light-reflecting material, and the detection module can replace the light-reflecting component. In this way, the detection module can realize the light-reflecting effect and the detection effect.

[0070] In some embodiments, the seventh side of the detection module is arranged with a light-reflecting material to reflect the third light emitted from the fourth side of the light-emitting component to form part of the first light. In this way, the detection module can reflect the third light emitted by the light-emitting component, or reflect the third light together with the light-reflecting component, without affecting the formation of the first light by the third light.

[0071] In some embodiments, the electronic device further includes a first structure including a first space in which the light-emitting component and the light-reflecting component are arranged, and the first space has a first opening, and a direction of the first opening satisfies the same condition as a detection direction of the detection module.

[0072] A second structure is arranged on the first structure and includes a second space in which at least part of the detection module is arranged, and the second space has a second opening, and a direction of the second opening satisfies the same condition as the detection direction of the detection module.

[0073] The first structure includes a first space in which the light-emitting component and the light-reflecting component are arranged, and the first structure has an eighth side, and a direction of the eighth side satisfies the same condition as the detection direction of the detection module. The second structure is arranged on the eighth side, and the second structure includes a second space in which at least part of the detection module is arranged.

[0074] In some embodiments, as Figure 2BAs shown, the first structure 14 includes a first space accommodating the light emitting component 112 and the light reflecting component 113, and the first space has a first opening, and the direction of the first opening meets the same condition as the detection direction of the detection module. The eighth side of the first structure can refer to a side facing the fourth side, and thus the direction of the eighth side (the direction of the first opening) meets the same condition as the detection direction of the detection module. For example, the first structure can be an iron back plate accommodating the light emitting component and the light reflecting component, and the direction of the first opening of the iron back plate can be consistent with the detection direction of the detection module, or the detection direction of the detection module can include the direction of the first opening, or the direction of the first opening can include the detection direction of the detection module.

[0075] In some embodiments, as shown in FIG. 1, the eighth side can be a side facing the fourth side. Figure 2B As shown, the eighth side can also be a side facing away from the fourth side.

[0076] Here, the second structure 141 is arranged on the maximum stress surface (the eighth side) of the first structure 14, and the extension direction of the second structure 141 is consistent with the maximum stress direction of the first structure 14. For example, the second structure can be a reinforcing rib of the first structure, which locally increases the rigidity of the first structure 14.

[0077] In the implementation process, since the second structure 141 has a certain thickness, a second space for accommodating at least part of the detection module can be arranged on the second structure, and the second space has a second opening, and the direction of the second opening meets the same condition as the detection direction of the detection module. Placing the detection module in the second space is beneficial to enhance the stability of the detection module. For example, a groove for accommodating the detection module can be arranged on the reinforcing rib, and the direction of the second opening of the groove can be consistent with the detection direction of the detection module, or the detection direction of the detection module can include the direction of the second opening (the case that the detection module is not completely placed in the groove), or the direction of the second opening can include the detection direction of the detection module (the case that the detection module is completely placed in the groove).

[0078] In some embodiments, the material strength of the second structure can be higher than the material strength of the first structure, or, in the case that the first structure and the second structure are made of the same material, the thickness of the second structure can be greater than the thickness of the first structure, so as to increase the rigidity and strength of the first structure.

[0079] Figure 2D A side view of a first structure provided by an embodiment of the present application is shown in FIG. 1, which includes a first structure 14 and a second structure 141. Figure 2DAs shown, the side view includes the first structure 21, the second structure 22, the rear shell 23, the detection module 12 and the processing module 13, wherein the detection module 12 is arranged in the second space of the second structure 22, the processing module 13 is arranged on the eighth side of the first structure which is opposite to the detection direction, and the rear shell 23 is further arranged for accommodating the first structure 21, the second structure 22, the detection module 12 and the processing module 13, so as to increase the integrity and reliability of the electronic device.

[0080] For example, when the detection module is a millimeter radar wave transmitting and receiving module, the millimeter radar wave transmitting and receiving module can be arranged in the second space of the second structure 22, which is a hidden millimeter radar wave transmitting and receiving module; and the thickness of the electronic device is not increased, and the design effect of the whole machine is not affected.

[0081] Figure 2E A rear view of a display screen provided by the embodiment of the application is shown in Figure 2E As shown, the schematic view includes the detection module 12 and the back plate reinforcing rib (the second structure) 22, wherein the detection module 12 includes a high-frequency radio (millimeter radar wave transmitting and receiving) component 121, a high-frequency radio component 122 and a high-frequency radio component 123, any of the high-frequency radio components can be designed as single transmission and double reception, that is, Figure 2E As shown, each high-frequency radio component includes one transmitting antenna and two receiving antennas; the back plate reinforcing rib 22 is arranged transversely on the rear side of the display screen, and the back plate reinforcing rib 22 can be used to accommodate the high-frequency radio component 121, the high-frequency radio component 122 and the high-frequency radio component 123.

[0082] In the embodiment of the application, the light emitting component and the light reflecting component are placed in the first space of the first structure, which can effectively increase the integrity and stability of the light emitting component and the light reflecting component; the second structure is arranged on the eighth side of the first structure and includes the second space for accommodating at least part of the detection module, which can effectively increase the strength and rigidity of the first structure and ensure the stability of the detection module.

[0083] In some embodiments, the detection module includes at least two detection components; the detection directions of the at least two detection components satisfy different conditions; wherein the first detection component and the second detection component are different in form.

[0084] Here, the detection directions of the at least two detection components satisfy different conditions, that is, the at least two detection components have detection directions that the other does not have. The arrangement mode includes at least one of the following: the two detection components have a small amount of overlapping detection range, the detection range of one detection component completely includes the detection range of the other detection component (one large and one small detection range detection component), and any two detection components do not have overlapping detection range.

[0085] In some embodiments, the two different detection directions include a first detection sub-direction and a second detection sub-direction; a form of the detection component corresponding to the first detection sub-direction is different from a form of the detection component corresponding to the second detection sub-direction.

[0086] In some embodiments, the detection module can be a single module, and the form of the detection module can be divided into two parts, wherein the first part can be adapted to the form of the space for accommodating the detection module, and the second part can be designed to attach the transceiving antennas in different directions, so that the detection module can realize the detection function in different detection directions to meet the detection requirements. For example, the cross section of the second part can be a hemisphere, a semi-ellipse, or a polygon containing multiple angles.

[0087] In some embodiments, the first side includes a first edge; wherein the distance between the first detection component and the first edge is less than the distance between the second detection component and the first edge; the angle between the detection direction of the first detection component and the first edge and the angle between the detection direction of the second detection component and the first edge satisfy the greater than condition; wherein the first detection component corresponds to a first form, and the second detection component corresponds to a second form, the first form is a form capable of forming a trapezoid or a triangle in a reference cross section; the second form is a form capable of forming a rectangle or a trapezoid in a reference cross section; wherein the reference cross section is a face satisfying the perpendicular condition with the first edge.

[0088] Here, the distance between the first detection component and the first edge is less than the distance between the second detection component and the first edge, that is, the first detection component can be arranged closer to the first edge than the second detection component.

[0089] In the implementation process, the angle between the center line of the first detection component corresponding to the detection direction and the first edge can be greater than the angle between the center line of the second detection component corresponding to the detection direction and the first edge; since the angle between the detection direction of the first detection component and the first edge not only includes the angle between the center line of the first detection component corresponding to the detection direction and the first edge, but also includes the angle between the remaining detection direction and the first edge except the center line, and similarly, the angle between the detection direction of the second detection component and the first edge also includes the angle between the remaining detection direction and the first edge except the center line, so the angle between the detection direction of the first detection component and the first edge and the angle between the detection direction of the second detection component and the first edge satisfy the greater than condition. In some embodiments, the detection direction of the first detection component is more inclined to the first edge than the detection direction of the second detection component.

[0090] In the case where the detection module includes at least two detection components, as Figure 2EAs shown, the detection module 12 includes detection component 121, detection component 122 and detection component 123, and the first side includes first edge 31, first edge 32, first edge 33 and first edge 34. The distance between detection component 121 and first edge 32 is less than the distance between detection component 122 and first edge 32; the distance between detection component 123 and first edge 31 is less than the distance between detection component 122 and first edge 31. Here, the first edge 31 and the second edge 32 can be the left and right sides of the display screen, respectively, or the first edge 33 and the first edge 34 can be the upper and lower sides of the display screen, respectively.

[0091] Figure 3 A top view of a detection component provided by an embodiment of the present application, Figure 3 In combination Figure 2E As can be seen, the angle between the detection component 121 and the first edge and the angle between the detection direction of the detection component 122 and the first edge satisfy the greater condition, that is, the detection direction of the detection component 121 is more biased toward the first edge 32 than the detection direction of the detection component 122; the detection direction of the detection component 123 is more biased toward the first edge 31 than the detection direction of the detection component 122.

[0092] The first detection component corresponds to a first shape, and the second detection component corresponds to a second shape. The first shape is a shape capable of forming a trapezoid or a triangle in a reference cross section; the second shape is a shape capable of forming a rectangle or a trapezoid in a reference cross section; and the reference cross section is a face that satisfies the perpendicular condition with the first edge.

[0093] As shown, Figure 3 The first detection component can include detection component 121, and the reference cross section of the detection component 121 that satisfies the perpendicular condition with the first edge can be a right triangle or a trapezoid, and the cross section of the detection component where the hypotenuse of the right triangle or the trapezoid is located faces the seventh side.

[0094] The first detection component can include detection component 123, and the reference cross section of the detection component 123 that satisfies the perpendicular condition with the first edge can be a right triangle or a trapezoid, and the cross section of the detection component where the hypotenuse of the right triangle or the trapezoid is located faces the seventh side.

[0095] The seventh side of the detection component 122 is not inclined, that is, the reference cross section of the detection component 122 that satisfies the perpendicular condition with the first edge can be a rectangle or a trapezoid; and the cross section of the detection component where any side of the rectangle or the mutually parallel short side or long side of the trapezoid is located faces the seventh side.

[0096] In some embodiments, the detection component can also be arranged close to the first edge 33 or close to the first edge 34 according to actual needs to achieve the coverage of the required detection direction.

[0097] In some embodiments, the detection assemblies can be arranged in different columns, for example, as shown in the detection assembly 121 and the detection assembly 123 placed on the two sides of the detection assembly 122 to cover different detection angles. Figure 3

[0098] The detection module further comprises an adjusting assembly connected with the detection module, used for adjusting the detection direction of the detection module. For example, the adjusting assembly can be a motor, a coupling, a rotating shaft and an encoder, wherein the motor is connected with the rotating shaft through the coupling, and the encoder is arranged on the rotating shaft and used for reading the rotation angle of the rotating shaft to adjust the detection direction of the detection module.

[0099] In the embodiments of the present application, the detection module comprises at least two detection assemblies with different detection directions; wherein the first detection assembly and the second detection assembly are different in form. In this way, at least two detection assemblies are arranged to cover different detection directions, so as to meet the detection requirements of the user.

[0100] The present application provides a flowchart of a control method, as shown in Figure 4A The method comprises the following steps:

[0101] In step S410, the display module outputs an image to the first side of the display module.

[0102] In step S420, the detection module emits a wireless detection signal and receives a returned wireless feedback signal; wherein the detection module is arranged on the second side of the display module, and the first side and the second side are opposite sides of the display module.

[0103] In step S430, if the processing module determines that the wireless feedback signal meets a first condition, the output of the display module is controlled to be switched.

[0104] In the embodiments of the present application, the display module outputs an image to the first side of the display module; the detection module emits a wireless detection signal and receives a returned wireless feedback signal; and if the processing module determines that the wireless feedback signal meets a first condition, the output of the display module is controlled to be switched. In this way, the display of the electronic device can be switched based on the wireless feedback signal received by the detection module to meet the needs of the customer, and the energy consumption of the electronic device can also be reduced.

[0105] In some embodiments, the first condition is met when the target object parameter in the detection range of the detection module meets the condition; and the step S430 "if the processing module determines that the wireless feedback signal meets a first condition, the output of the display module is controlled to be switched" can be realized by the following process:

[0106] ​If the processing module determines that the wireless feedback signal represents that the target object parameter in the detection range of the detection module meets the condition, the working state of the light-emitting component in the display module is controlled to be switched; or, the working state of the display component in the display module is controlled to be switched; or, the display image of the display component is controlled to be switched.

[0107] In some embodiments, when the processing module determines that the wireless feedback signal represents that there are multiple target objects, the output of the display module can be switched to a first state; when the processing module determines that the wireless feedback signal represents that there is one target object viewing the output image of the display module, the output of the display module can be switched to a second state; when the processing module determines that the wireless feedback signal represents that there is no target object viewing the output image of the display module, the output of the display module can be switched to a third state; wherein the first state can be a feedback mode for protecting user privacy, the second state can be a state of the display module working normally; and the third state can be a state of the display module not outputting a display image, i.e., a non-working state of the display module, so as to achieve the effect of reducing power consumption.

[0108] Here, the first condition includes that the target object parameter in the detection range of the detection module meets the condition. In the implementation process, the target object parameter includes at least one of the following: the number of users, the position of the user, and the orientation of the user. For example, the target object parameter meets the requirement that there are two or more target objects located on the first side of the output image, i.e., the front of the display screen; the target object parameter meets the requirement that there are two or more target objects located on the first side of the output image and facing the first side of the output image; and the target object parameter meets the requirement that there is one target object located on the first edge direction of the first side of the output image, i.e., the side of the display screen. Since the user located in front of the display screen can clearly see the display screen, in order to achieve the effect of preventing peeping, the output image of the display screen needs to be processed; similarly, the user located on the side of the display screen can also see part or all of the output image of the display screen based on the different positions of the user, in order to achieve the effect of preventing peeping, the output image of the display screen also needs to be processed.

[0109] In some embodiments, the working state of the light-emitting component in the display module can be controlled to be switched, which can be adjusting the light-emitting degree of the light-emitting component, for example, the light-emitting component can be turned off, the light emitted by the light-emitting component can be dimmed, or the light-emitting component can be turned on.

[0110] In some embodiments, the working state of the display component in the display module can be controlled to be switched, which can be adjusting the deflection angle of the liquid crystal in the display component, so as to achieve the effect that the output image of the display screen cannot be observed at a partial observation angle.

[0111] In some embodiments, controlling the switching of the display image of the display component can be achieved by using a processing module to switch the display image, or by using an external processing component connected to the electronic device to switch the display image. For example, the main control chip built into the display screen can be used to switch the display image, or the processor of the host connected to the display screen can be used to switch the display image.

[0112] Figure 4B This application provides a flowchart illustrating a control for switching the output of a display module, as shown in the embodiment. Figure 4B As shown in the diagram, the process flow includes:

[0113] Step S431: The main control chip receives the wireless feedback signal;

[0114] During implementation, if the millimeter radar wave transmitting and receiving module communicates directly with the main control chip, the main control chip will directly receive the wireless feedback signal.

[0115] During implementation, such as Figure 1B As shown, if an artificial intelligence sensor and a digital processing chip 41 are provided, the digital processing chip processes the wireless feedback signals obtained from the millimeter radar wave transmitting and receiving module 1, the millimeter radar wave transmitting and receiving module 2 and the millimeter radar wave transmitting and receiving module 3, and sends the processed wireless feedback signals to the main control chip 13.

[0116] Step S432: When the main control chip determines that the wireless feedback signal meets the first condition, it controls the switching of the output of the display module. The switching method includes at least one of the following three methods: backlight on / off, screen blurring / clarification, or adjustable viewing angle.

[0117] During implementation, the main control chip determines that the wireless feedback signal meets the first condition and controls the switching of the output of the display module. Depending on the actual situation, one of the three switching modes—backlight on / off, screen blurring / clarification, or adjustable viewing angle—can be selected to switch the output of the display module.

[0118] In practical use, controlling the switching of the display module's output can be achieved using a control method based on radio wave technology to implement under-screen privacy protection, such as... Figure 1C As shown, when the processing module determines that a second person or two or more people are looking at the display screen at a certain angle (±30 degrees or ±45 degrees), it can automatically adjust the viewing angle of the LCD to achieve privacy protection within that angle range (i.e., it cannot be seen outside the ±30 degree or ±45 degree viewing angle), while not affecting the use of the actual user 21 using the electronic device, and vice versa.

[0119] Or when the processing module determines that the second person or more than two people stand in the visual angle range of the user 21 (i.e. between positive and negative 30 degrees), the heart rate of the second person or more than two people can be detected, and the displacement change or speed change, etc. The processing module can realize the partial or whole blurring of the screen, so as to remind the user that someone is observing the display screen of the electronic device, and vice versa.

[0120] Here, the radio wave belongs to the millimeter ultrasonic wave, and the non-destructive real-time monitoring can effectively solve the annoyance of being spied when the user uses the display screen of the electronic device. The millimeter radar wave is a high-frequency radio wave, which can reach a transmission frequency of 60GHz. According to the actual situation, the transmission frequency can be dynamically adjusted, such as 55GHz to 65GHz, so as to realize different detection distances and improve the corresponding accuracy.

[0121] In some embodiments, the processing module determines that no one uses the display screen of the electronic device, which can set the display into black screen mode (turn off the backlight or display monochrome contentless image), so as to achieve the effect of power saving, and vice versa.

[0122] In some embodiments, the electronic device further comprises an image acquisition device for acquiring the target object, and the processing module is further configured to acquire the image of the target object when the wireless feedback signal meets the first condition, so as to determine whether the image meets the third condition, and control the switching of the display of the electronic device.

[0123] Here, the orientation of the target object watching the screen in the acquisition range can also be determined by the camera device arranged on the display screen, that is, the third condition can be determined that the target object faces the display screen. For example, the number of target objects and the position of the target objects can be determined by the detection assembly first, and then the orientation of the target objects can be determined by the camera device when more than two target objects are determined to exist. In this way, the energy consumption of the camera device can be reduced, and the detection assembly can also assist the detection assembly to more accurately determine whether the target object meets the condition of watching the screen, so as to effectively complete the subsequent control of the output of the display module.

[0124] In some embodiments, as Figure 4CAs shown, the artificial intelligence sensor and the digital processing chip 41 can be connected with the image acquisition device 42, used to collect the use habits of the user, and integrate the collected data into big data, so that the user does not need to set any settings. After the processing module automatically controls the wireless feedback signal to meet the first condition in the corresponding environment, the display of the electronic device is controlled to switch. The artificial intelligence sensor and the digital processing chip 41 can be connected with the detection module 12 and the image acquisition device 42 at the same time, based on a large amount of detection materials collected by the detection module 12, combined with a large amount of image materials collected by the image acquisition device 42, the use habits of the user are analyzed. For example, in the case of analyzing that the user will leave the display screen when watching the environment changes to multi-person watching, the wireless feedback signal can be set to represent the case that multiple target objects exist, and the backlight is switched off, so that the entire implementation process is more intelligent and more accurate.

[0125] In some embodiments, the processing of the user in a specific environment obtained by the processing device connected with the electronic device can also be combined to determine the processing module to automatically control the display of the electronic device in the corresponding environment. For example, in the case of analyzing that the user will probably perform the operation of closing the display or closing a certain application interface when the detection environment changes to multi-person watching at 60 degrees and 1.5 meters, the wireless feedback signal can be set to represent the case that multiple target objects exist in the detection environment of 60 degrees and 1.5 meters, and the operation of controlling the working state of the light emitting component in the display module, or controlling the working state of the display component in the display module, or controlling the display image of the display component is performed to match the different needs of the user and bring good user experience. Among them, the artificial intelligence sensor and the digital processing chip 41 and / or the processing module recognize the operation of closing the application interface on the image output device side through the analysis of the display image.

[0126] In the embodiments of the present application, in the case that the target object parameters in the detection range meet the conditions, the working state of the light emitting component in the display module is switched, or the working state of the display component in the display module is controlled to switch, or the display image of the display component is controlled to switch, to meet the use requirements of the user.

[0127] In some embodiments, before the detection module emits the wireless detection signal, the method further comprises: in the case that the detection adjustment signal meets the second condition, the detection module switches the first detection direction set to the second detection direction set, wherein the first detection direction set is different from the second detection direction set.

[0128] In some embodiments, the detection distance can be automatically adjusted for different usage scenarios, such as adjusting the detection distance to 1.5 meters or 2 meters. Here, the detection distance can be adjusted by adjusting the transmission frequency and transmission power of the detection module. In some embodiments, the detection distance can also be adjusted based on the detection of a potential target object at a certain distance within a certain period of time. Alternatively, the detection distance can be adaptively adjusted based on the size of the display screen. For example, if the initial distance of the detection module is adapted to a 19-inch display, and the processing module determines that the display size of its own electronic device is 15 inches, the detection distance of the detection module is automatically reduced; if the display size of its own electronic device is determined to be 24 inches, the detection distance of the detection module is automatically increased. This allows for effective detection of displays of any size while reducing power consumption when adapting to smaller displays.

[0129] In some embodiments, manual adjustment signals can be input using on-screen display (OSD). The OSD menu is a rectangular menu that pops up on the screen after pressing the Menu button, displaying various display adjustment options. This menu allows adjustment of various display parameters, including color, mode, and geometry, to achieve optimal performance. Unlike signals from other devices that are received, parsed, and then reproduced into a reconstructed image, the OSD menu is an image generated by the processing module based on the display's internal firmware. Furthermore, the image generated by the processing module based on the display's internal firmware has higher display priority than the image received and reproduced by the communication module. That is, when the OSD menu is displayed, it obscures or partially obscures the image received and reproduced by the communication module.

[0130] Multiple modes can be selected in the OSD menu. Figure 4D An OSD menu provided for embodiments of this application, such as Figure 4B As shown, the OSD menu includes Personalization 46. When the user selects Personalization 46, they can choose Automatic, On, or Off. When the user selects On, they can continue to select a detection distance of 1.5 meters, a detection distance of 2.0 meters, a detection angle of 60 degrees, or a detection angle of 90 degrees.

[0131] During implementation, the first detection direction set can be switched to the second detection direction set based on the user's settings on the OSD menu.

[0132] In the embodiments of the present application, before the detection module transmits the wireless detection signal, the detection module switches the first detection direction set to the second detection direction set in a case where the detection adjustment signal meets the second condition, wherein the first detection direction set is different from the second detection direction set, and the detection adjustment signal includes an automatically generated adjustment signal and a manually input adjustment signal. In this way, the electronic device can set the detection direction based on the detection adjustment signal to meet the use demand of the user.

[0133] Based on the foregoing embodiments, the embodiments of the present application provide a control device, which includes various components and can be implemented by a processor in an electronic device; of course, it can also be implemented by a specific logic circuit; in the implementation process, the processor can be a central processing unit (CPU), a microprocessor (MPU), a digital signal processor (DSP), or a field programmable gate array (FPGA), etc.
