[0037] Figure 1 The block diagram of a display device showing an embodiment of the present application is presented. A display device provided by an embodiment of the present application, as Figure 1 shown, includes:

[0038] A first interface for connecting to an electronic device 20, including a first transmission channel capable of transmitting communication data between the display device 10 and the electronic device 20, and a second transmission channel capable of obtaining a first image signal and a second image signal output by the electronic device 20;

[0039] A first processing unit 30 for generating a first control signal based on the first image signal;

[0040] An image output unit 40 for outputting a first image corresponding to the first image signal based on the first control signal;

[0041] A first acquisition module 50 for acquiring an environmental image corresponding to the display device 10;

[0042] A second processing unit 60, configured to generate a first output signal when the environmental image and the second image corresponding to the second image signal meet a preset matching condition; and output the first output signal to the electronic device 20 through the first transmission channel.

[0043] The display device 10 of this embodiment has functions of data processing and image acquisition. For example, the display device 10 can be a display with a processing chip and is provided with a camera for image acquisition. The display device 10 of this embodiment includes a first interface for connecting to the electronic device 20. For example, the first interface can be a USB-HUB interface; the electronic device 20 can be an electronic device with data transmission and image processing functions, and the electronic device 20 interacts with the display device 10. For example, the electronic device 20 can be a laptop or a desktop computer; the electronic device 20 can also be configured with a target application. The user can use the camera of the display device 10 to capture a face image and register the target application based on the face image. The target application can be a Windows Hello biometric authorization application.

[0044] The first interface of the display device 10 includes a first transmission channel, which can enable communication data to be transmitted between the display device 10 and the electronic device 20. For example, the first transmission channel can be a Type-C pin, and the display device 10 can send a signal instruction to the electronic device 20 through the first interface; the first interface of the display device 10 also includes a second transmission channel, which can obtain a first image signal and a second image signal output by the electronic device 20. The second transmission channel can be a pin for transmitting an image signal. For example, the second transmission channel can be a GPIO (General-purpose input / output) pin. The image corresponding to the first image signal is the first image, and the first image can be an image displayed by the electronic device 20 in the locked screen state; the image corresponding to the second image signal is the second image, and the second image can be a face image pre-stored by the user when registering the target application.

[0045] The display device 10 further includes a first processing unit 30. The first processing unit 30 may be a display driver chip Scalar. After the electronic device 20 outputs the first image signal to the first processing unit 30 of the display device 10 through the second transmission channel, the first processing unit 30 generates a first control signal based on the first image signal. The first control signal is an electrical signal used to determine the first image to be displayed by the electronic device 20. When the user does not trigger the target application, the electronic device 20 can be maintained in the locked screen state. The electronic device 20 may output the first image signal corresponding to the locked screen state to the first processing unit 30. The first processing unit 30 generates a first control signal based on the first image signal, and based on the first control signal, it can determine the first image corresponding to the locked screen state of the electronic device 20, and then control the electronic device 20 to maintain the locked screen state.

[0046] The display device 10 further includes an image output unit 40. The image output unit 40 may be the control panel of the display device 10. After the first processing unit 30 generates the first control signal based on the first image signal, it can send the first control signal to the image output unit 40. Based on the first control signal, the image output unit 40 can determine the first image corresponding to the first image signal and output the first image corresponding to the first image signal to the electronic device 20, so that the electronic device 20 displays the first image in the locked screen state, thereby maintaining the electronic device 20 in the locked screen state when the user does not trigger the target application.

[0047] The display device 10 further includes a first acquisition module 50. The first acquisition module 50 may be an RGB camera. The first acquisition module 50 is used to acquire the environmental image corresponding to the display device 10. When the target object appears in front of the display device 10, the first acquisition module 50 can acquire the image of the target object. For example, when the user needs to trigger the target application, they can approach the RGB camera of the display, and the RGB camera can acquire the facial image of the current user.

[0048] The display device 10 further includes a second processing unit 60. The second processing unit 60 can be an ISP (Image Signal Processor) image processor, and the second processing unit 60 can also be an NPU (Neural network Processing Unit) neural network processor. After the first acquisition module 50 acquires the environmental image, the environmental image can be given to the second processing unit 60. The second processing unit 60 compares the environmental image with the second image corresponding to the second image signal to determine whether the environmental image and the second image corresponding to the second image signal meet the preset matching condition. If the environmental image and the second image meet the preset matching condition, it indicates that the image information of the environmental image matches the image information of the second image; if the environmental image and the second image do not meet the preset matching condition, it indicates that the image information of the environmental image does not match the image information of the second image. When the environmental image and the second image corresponding to the second image signal meet the preset matching condition, the second processing unit 60 can generate a first output signal. The first output signal can be a signal for simulating an input device 80. For example, the first output signal can be an analog mouse signal. After generating the first output signal, the second processing unit 60 can output the first output signal to the electronic device 20 through the first transmission channel, so that the electronic device 20 triggers the login interface of the target application.

[0049] For example, when a user needs to log in to Windows Hello, the user can approach the RGB camera of the monitor to make the RGB camera capture the user's facial image; then, the ISP image processor compares the facial image captured by the RGB camera with the facial image pre-stored when the user registered Windows Hello to determine whether the facial image captured by the RGB camera and the facial image pre-stored when the user registered Windows Hello match; when the facial image captured by the RGB camera and the facial image pre-stored when the user registered Windows Hello match, it indicates that the current user has passed the identity verification of Windows Hello. The ISP image processor can generate an analog mouse signal and output the analog mouse signal to the electronic device 20, so that the electronic device 20 triggers the login interface of Windows Hello, and the user can log in to Windows Hello.

[0050] The display device 10 of the present application is connected to the electronic device 20. The second processing unit 60 compares the environmental image with the second image corresponding to the second image signal to determine whether the environmental image and the second image corresponding to the second image signal meet the preset matching condition. When the environmental image and the second image corresponding to the second image signal meet the preset matching condition, the second processing unit 60 can generate a first output signal and output the first output control signal to the electronic device 20 through the first transmission channel, so that the electronic device 20 triggers the login interface of the target application. The display device 10 of the present application can directly compare the image of the current target object with the pre-stored image through the second processing unit 60. When the target object passes the identity recognition, the electronic device 20 can quickly trigger the login interface of the target application. The user does not need to trigger the display device 10 or the electronic device 20, which ensures the safe use of the target application, reduces energy consumption, and improves the user experience.

[0051] In an embodiment of the present application, the second processing unit 60 is further configured to output a second output signal when the environmental image and the second image do not meet the preset matching condition, and output the second output signal to the first processing unit 30, so that the first processing unit 30 generates a second control signal based on the second output signal;

[0052] The image output unit 40 is further configured to output a second image corresponding to the second image signal based on the second control signal.

[0053] Specifically, as Figure 1As shown in the figure, after the second processing unit 60 compares the environmental image with the second image corresponding to the second image signal, if the environmental image and the second image do not meet the preset matching condition, it indicates that the image information of the environmental image does not match the image information of the second image, and the current target object fails the identity recognition of the target application. In this case, the ISP image processor can generate a second output signal and output the second output signal to the display driver chip Scalar. The second output signal can be a signal for controlling the analog input device 80 that keeps the electronic device 20 in the locked screen state. In response to the second output signal, the display driver chip Scalar reads the pre-stored data to generate a second control signal, and the second control signal is an electrical signal for determining the second image to be displayed by the electronic device 20. When the user's identity recognition fails and the target application is not successfully triggered, the electronic device 20 can be maintained in the locked screen state, and the electronic device 20 displays the second image, and the second image can indicate that the user fails the identity recognition. The electronic device 20 can output the second image signal to the display driver chip Scalar, and the display driver chip Scalar generates a second control signal based on the second image signal. Based on the second control signal, the second image corresponding to the second image signal can be determined, and the second image corresponding to the second image signal is output to the electronic device 20 for display. The second image can be used to prompt the user that the identity recognition fails. By displaying the second image on the electronic device 20, the user can be prompted to verify again. For example, the user can be prompted to pay attention to the camera angle, shooting light, and the problem of missing facial features through the second image; and when the electronic device 20 displays the second image, it still remains in the locked screen state.

[0054] In an embodiment of the present application, as Figure 2 shown, the display device 10 further includes a second acquisition module 70. The second processing unit 60 is further configured to control the second acquisition module 70 to acquire information when the environmental image and the second image meet the preset matching condition. In response to the information acquired by the second acquisition module 70 indicating that the position state of the target object meets the preset condition, a third output signal is generated, and the third output signal is output to the electronic device 20 through the first transmission channel.

[0055] Specifically, the second acquisition module 70 may be a TOF sensor. The second acquisition module 70 can be used to monitor the position state of the target object, and then determine the relative position relationship between the target object and the display device 10. When the environmental image and the second image meet the preset matching conditions, it means that the image information of the environmental image matches the image information of the second image, and the current target object passes the identity recognition of the target application. In this case, the second acquisition module 70 is controlled to collect the position information of the target object, and it is determined whether the position state of the target object meets the preset conditions. When the position state of the target object meets the preset conditions, it indicates that the relative position relationship between the target object and the display device 10 can meet the usage conditions of the target application. For example, the position of the target object is directly in front of the display device 10. In response to the information collected by the second acquisition module 70 indicating that the position state of the target object meets the preset conditions, the second processing unit 60 can generate a third output signal. The third output signal can be a signal for controlling the analog input device 80 that turns on the screen of the electronic device 20. After generating the third output signal, the second processing unit 60 can output the third output signal to the electronic device 20 through the first transmission channel, so that the electronic device 20 switches from the locked screen state to the working state, and the display screen of the electronic device 20 switches to the desktop display state. In this embodiment, when the position of the target object can meet the usage conditions of the target application, by directly triggering the third output signal, the electronic device 20 is controlled to switch from the locked screen state to the desktop working state, reducing the user's button interaction operation.

[0056] In an embodiment of the present application, the second processing unit 60 is further configured to, when the relative position relationship between the target object and the display device 10 meets the preset conditions, output the third output signal to the electronic device 20 through the first transmission channel, so that the electronic device 20 switches from the locked screen state to the working state based on the third output signal.

[0057] Specifically, when the environmental image and the second image meet the preset matching conditions, it indicates that the current target object has passed the identity recognition of the target application. The TOF sensor is controlled to collect the position information of the target object, and it is determined whether the relative position relationship between the target object and the display device 10 meets the preset conditions. When the relative position relationship between the target object and the display device 10 meets the preset conditions, it indicates that the relative position relationship between the target object and the display device 10 can meet the usage conditions of the target application. For example, when a user needs to log in to Windows Hello, if the facial image of the user captured by the RGB camera matches the facial image pre-stored when the user registered for Windows Hello, it indicates that the current user has passed the identity recognition of Windows Hello; in this case, the TOF sensor is used to collect the position information of the user, and it is determined whether the position of the user is in front of the display screen. If the position of the user is still in front of the display screen, an analog mouse signal can be generated by the ISP image processor and the analog mouse signal can be output to the electronic device 20, so that the electronic device 20 can switch from the locked screen state to the desktop working state without the user performing button interaction operations.

[0058] In an embodiment of the present application, as Figure 3 shown, the display device 10 further includes a second interface, and the second interface is used to connect to the input device 80 to obtain the input signal output by the input device 80; the second processing unit 60 is further used to output the input signal to the electronic device 20 through the first transmission channel, where the input device 80 information corresponding to the first output signal is different from the input device 80 information of the input device 80 connected through the second interface.

[0059] Specifically, the second interface can be a USB Type-C interface, and the input device 80 can be a device such as a keyboard or a mouse that is connected to the display device 10 through the second interface and has a signal input function. After the second interface is connected to the input device 80, the input signal output by the input device 80 can be obtained. The input signal output by the input device 80 can be an input signal generated when the user triggers the input device 80. For example, when the user presses the button of the mouse, the mouse can be triggered to generate a corresponding input signal, and the input signal is given to the display device 10 through the USB Type-C interface. The input device 80 information corresponding to the input signal can be the input device 80 information directly triggered by the input device 80.

[0060] The input signal output by the input device 80 may also be an input signal generated when the user triggers the target application. When the second processing unit 60 compares the environmental image with the second image and determines that the environmental image and the second image meet the preset matching conditions, it indicates that the current target object has passed the identity recognition of the target application. The second processing unit 60 may generate a first output signal. The input device 80 information corresponding to the first output signal may be the analog identification information of the input device 80. The input signal is output to the electronic device 20 through the first transmission channel, so that the electronic device 20 triggers the login interface of the target application.

[0061] In an embodiment of the present application, the second processing unit 60 is further configured to, when the environmental image and the second image meet the preset matching conditions, generate the identification information corresponding to the input device 80, and output the identification information corresponding to the input device 80 to the electronic device 20 through the first transmission channel, so that the electronic device 20 triggers the login interface of the target application.

[0062] Specifically, the face image captured by the RGB camera is compared with the face image pre-stored by the user when registering Windows Hello through the ISP image processor. When it is determined that the face image captured by the RGB camera matches the face image pre-stored by the user when registering Windows Hello, it indicates that the current user has passed the identity recognition of Windows Hello. The unique identification information corresponding to the mouse device can be generated by the ISP image processor and output to the electronic device 20, so that the electronic device 20 triggers the login interface of Windows Hello, allowing the user to log in to Windows Hello.

[0063] In an embodiment of the present application, as Figure 4As shown, the display device 10 further includes a storage module 90. The storage module 90 can be a Flash memory. The storage module 90 is connected to the second processing unit 60. Moreover, only the second processing unit 60 in the display device 10 has access to the storage module 90, and other processing units in the display device 10 except the second processing unit 60 have no access to the storage module 90. The second processing unit 60 is further configured to store the second image signal into the storage module 90. The second image can be a facial image pre-stored by the user when registering the target application. When the second processing unit 60 compares the environmental image with the second image corresponding to the second image signal, the second processing unit 60 can directly read the second image signal in the storage module 90 to obtain the second image. For example, when the user needs to log in to Windows Hello, the ISP image processor can read the second image signal in the Flash memory to obtain the facial image pre-stored when registering Windows Hello. Then, the ISP image processor compares the facial image captured by the RGB camera with the facial image pre-stored when the user registers Windows Hello to determine whether the facial image captured by the RGB camera matches the facial image pre-stored when the user registers Windows Hello. Thus, the Windows Hello identity recognition of the current user is completed.

[0064] In an embodiment of the present application, the second processing unit 60 is further configured to obtain the second image signal from the storage module 90, obtain the corresponding second image based on the second image signal, compare the second image with the environmental image to obtain the corresponding comparison result, and determine whether the environmental image and the second image meet the preset matching condition according to the comparison result.

[0065] Specifically, when the second processing unit 60 compares the environmental image with the second image corresponding to the second image signal, the second processing unit 60 can read the second image signal from the storage module 90 and obtain the corresponding second image based on the second image signal. For example, when the user needs to log in to Windows Hello, the ISP image processor can read the second image signal in the Flash memory to obtain the facial image pre-stored when registering Windows Hello; then, the ISP image processor compares the facial image captured by the RGB camera with the facial image pre-stored when the user registers Windows Hello to determine whether the facial image captured by the RGB camera matches the facial image pre-stored when the user registers Windows Hello; if the result of the comparison by the ISP image processor between the facial image captured by the RGB camera and the facial image pre-stored when the user registers Windows Hello is 1, it indicates that the current user has passed the Windows Hello identity recognition, and the login interface of Windows Hello can be triggered by the electronic device 20 to enable the user to log in to Windows Hello; if the result of the comparison by the ISP image processor between the facial image captured by the RGB camera and the facial image pre-stored when the user registers Windows Hello is 0, it indicates that the current user has not passed the Windows Hello identity recognition, and the electronic device 20 can be made to trigger and maintain the locked screen state.

[0066] This application also provides an electronic device 20, such as Figure 5 shown. The electronic device 20 can be an electronic device 20 with data transmission functions and image processing functions. For example, the electronic device 20 can be a laptop computer or a desktop computer; the electronic device 20 can also be configured with a target application. The user can use the camera of the display device 10 to capture a facial image and register the target application based on the facial image. The target application can be a Windows Hello biometric authorization application. The electronic device 20 of this embodiment includes:

[0067] A third interface for connecting to the display device 10. The third interface includes a first transmission channel capable of transmitting communication data between the electronic device 20 and the display device 10, and a second transmission channel capable of outputting a first image signal and a second image signal to the display device 10;

[0068] Specifically, the third interface can be a USB-HUB interface, and the first transmission channel can be a Type-C pin. The electronic device 20 can receive a signal instruction sent by the display device 10 through the third interface. The electronic device 20 can output a first image signal and a second image signal through the second transmission channel. The second transmission channel can be a pin for transmitting an image signal. For example, the second transmission channel can be a GPIO (General-purpose input / output) pin. The image corresponding to the first image signal is the first image, and the first image can be the image displayed by the electronic device 20 in the locked screen state. The image corresponding to the second image signal is the second image, and the second image can be the facial image pre-stored by the user when registering the target application.

[0069] The second processing unit 60 of the display device 10 compares the environmental image with the second image corresponding to the second image signal. When it is determined that the environmental image and the second image corresponding to the second image signal meet the preset matching condition, the second processing unit 60 can generate a first output signal. The first output signal can be a signal for simulating the input device 80. For example, the first output signal can be an analog mouse signal. The electronic device 20 obtains the first output signal output by the display device 10 through the first transmission channel. And in response to the electronic device 20 obtaining the first output signal, when the environmental image corresponding to the display device 10 and the second image corresponding to the second image signal meet the preset matching condition, the pre-stored image is used to identify the environmental image, and a corresponding identification result is obtained.

[0070] For example, when the user needs to log in to Windows Hello, they can approach the RGB camera of the monitor to make the RGB camera capture the user's facial image. Then, the facial image captured by the RGB camera is compared with the facial image pre-stored by the user when registering Windows Hello through the ISP image processor to determine whether the facial image captured by the RGB camera and the facial image pre-stored by the user when registering Windows Hello match. When the facial image captured by the RGB camera and the facial image pre-stored by the user when registering Windows Hello match, it indicates that the current user has passed the identity recognition of Windows Hello. An analog mouse signal can be generated through the ISP image processor and output to the electronic device 20, causing the electronic device 20 to trigger the login interface of Windows Hello, and the user can then log in to Windows Hello.

[0071] In an embodiment of the present application, when the recognition result of the environmental image indicates that the environmental image matches a pre-stored image, the electronic device 20 obtains the third output signal output by the display device 10 through the first transmission channel, and in response to the electronic device 20 obtaining the third output signal, when the acquisition information of the display device 10 indicates that the position state of the target object meets a preset condition, the locked screen state of the electronic device 20 is switched to the working state.

[0072] Specifically, the second acquisition module 70 of the display device 10 can monitor the position state of the target object, and then determine the relative position relationship between the target object and the display device 10. When the environmental image and the second image meet the preset matching condition, it means that the image information representing the environmental image matches the image information of the second image, and the current target object has passed the identity recognition of the target application. In this case, the second acquisition module 70 acquires the position information of the target object and determines whether the position state of the target object meets the preset condition. When the position state of the target object meets the preset condition, it indicates that the relative position relationship between the target object and the display device 10 can meet the usage conditions of the target application. For example, the position of the target object is directly in front of the display device 10. In response to the information acquired by the second acquisition module 70 indicating that the position state of the target object meets the preset condition, the second processing unit 60 of the display device 10 can generate a third output signal. The third output signal can be a signal for controlling the analog input device 80 that turns on the screen of the electronic device 20. After generating the third output signal, the second processing unit 60 can output the third output signal to the electronic device 20 through the first transmission channel. The electronic device 20 obtains the third output signal output by the second processing unit 60 of the display device 10 through the first transmission channel, and in response to the electronic device 20 obtaining the third output signal, when the acquisition information of the display device 10 indicates that the position state of the target object meets the preset condition, the locked screen state of the electronic device 20 is switched to the working state, and the display screen of the electronic device 20 is switched to the desktop display state. In this embodiment, when the position of the target object can meet the usage conditions of the target application, the electronic device 20 is switched from the locked screen state to the desktop working state, reducing the user's key interaction operations.
