The desktop area information includes desktop object movement information and user hand activity information, and the user area information includes user proximity information and main user presence information. The power consumption and detection accuracy of the second sensor are higher than those of the first sensor. An auxiliary controller is connected to the first sensor, the second sensor, and the display component; and, The main control processor is connected to the second sensor, the display component, and the auxiliary controller.

[0006] The present invention also provides a control method for a display system, applied to the above-mentioned display system, the control method comprising: The operating status of the display system is obtained, including a locked state where the display components, the main control processor, and the second sensor are all locked, and an unlocked state where the second sensor is running. If the display system is in the locked state, it enters a low-power detection mode. In the low-power detection mode, the following operations are performed: control the first sensor to collect motion and static information of the front area of ​​the display component; determine whether to exit the low-power detection mode and turn on the second sensor to enter a high-precision detection mode based on the motion and static information. If the display system is in the unlocked state, it enters a high-precision detection mode. In the high-precision detection mode, the following operations are performed: acquiring display information of the display component; controlling the second sensor to collect desktop area information and user area information in front of the display component; and controlling the operation of the display component, the main processing controller, and the second sensor based on the display information, the desktop area information, and the user area information.

[0007] Optionally, the step of determining whether to exit the low-power detection mode and enter the high-precision detection mode based on the motion information includes: If the dynamic information is: a change from static (object stationary and no user present) to dynamic (object moving or user present), then it is determined to exit the low-power detection mode and enter the high-precision detection mode.

[0008] Optionally, in the high-precision detection mode, when both the display component and the main control processor are locked, the step of controlling the operation of the display component, the main processing controller, and the second sensor based on the display information, the desktop area information, and the user area information includes: If in the user area information, the main user presence information indicates that the main user is not present, and the user proximity information indicates that a user is approaching; and in the desktop area information, the desktop item movement information indicates that the desktop item remains stationary, and the user hand activity information indicates that there is no hand activity; Then, the display component is controlled to enter the pending confirmation state, and the main control processor is controlled to remain locked.

[0009] Optionally, in the high-precision detection mode, when both the display component and the main control processor are locked, the step of controlling the operation of the display component, the main processing controller, and the second sensor based on the display information, the desktop area information, and the user area information includes: If in the user area information, the main user presence information indicates that the main user is not present, and the user proximity information indicates that a user is approaching; and in the desktop area information, the desktop item movement information indicates that a desktop item has been moved, or the user hand activity information indicates that a hand activity has occurred; Then the display component and the main control processor are awakened and put into operation.

[0010] Optionally, the step of controlling the operation of the display component, the main processing controller, and the second sensor based on the display information, the desktop area information, and the user area information includes: If the user area information includes information such as "main user present" indicating that the main user is present, and "user proximity" indicating that someone else has entered the private area behind the main user; Then determine whether the content displayed in the information is sensitive content; If so, the display component is controlled to blur the displayed content.

[0011] Optionally, in the high-precision detection mode, when both the display component and the main control processor are working, the step of controlling the operation of the display component, the main processing controller, and the second sensor based on the display information, the desktop area information, and the user area information includes: If in the user area information, the main user's presence information indicates that the main user has left their seat; and in the desktop area information, the desktop item movement information indicates that the desktop item is stationary, and the user's hand activity information indicates that there is no hand activity; Then obtain the duration of time the main user leaves the seat, the items on the table remain still, and there is no hand movement; If the duration reaches the first preset duration, the display mode of the display component is controlled according to the sensitivity of the content displayed in the display information.

[0012] Optionally, the step of controlling the display mode of the display component according to the sensitivity of the displayed content in the display information includes: If the sensitivity of the displayed content is low, then the display component is controlled to display at low brightness; And / or, if the sensitivity of the displayed content is high, then the display component is controlled to blur the displayed content.

[0013] Optionally, the control method further includes: If the duration reaches the second preset duration, the display component and the main control processor are locked. Wherein, the second preset duration is longer than the first preset duration.

[0014] Optionally, the control method further includes: If the duration reaches the third preset duration, the second sensor is turned off, the high-precision detection mode is exited, and the low-power detection mode is entered. The third preset duration is longer than the second preset duration.

[0015] The display system provided by the present invention can execute the above-mentioned control method. When the display system is in a locked state where it is not in operation and in an unlocked state where the operating conditions may change, different sensors are used to enter different detection modes. In the locked state, a low-power detection mode is entered, using a low-power first sensor and an auxiliary controller to achieve a rough detection of the dynamic and static information of the front area of ​​the display components with low power consumption, and to predict the operating conditions that the display system is about to enter. When unlocked, the system enters a high-precision detection mode, employing a second sensor to simultaneously and precisely detect dynamic information from both the desktop and user areas. By integrating information from both areas, the system accurately determines the current and upcoming operating conditions of the display system, and accordingly controls the operation of the display components and main control processor to match these conditions. This improves the accuracy of adjustments to the display components and main control processor in areas such as holding, waking up, locking, and processing display content, thereby enhancing the user experience. Simultaneously, based on the current and upcoming operating conditions of the display system, the system adjusts the on / off state of the second sensor to ensure accurate detection of the desktop and user areas when unlocked, and to reduce the high power consumption of the second sensor when the display system is locked. This achieves precise identification and control of the display system, improving the user experience while reducing power consumption and lowering costs. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] This embodiment provides a display system, including a display component, a first sensor, a second sensor, an auxiliary controller, and a main control processor. The display component includes at least a display screen. The first sensor is disposed on the display component and is used to detect motion information in the front area of ​​the display component. The second sensor is disposed on the display component and is used to detect desktop area information and user area information in the front area of ​​the display component. The desktop area information includes information on the movement of desktop objects and user hand movements, and the user area information includes user proximity information and main user presence information. The auxiliary controller is connected to the first sensor, the second sensor, and the display component. The main control processor is connected to the second sensor, the display component, and the auxiliary controller. The power consumption and detection accuracy of the second sensor are higher than those of the first sensor, and the power consumption and control accuracy of the main control processor are higher than those of the auxiliary controller.

[0022] In the display system provided in this embodiment, the display component includes a display screen, which has a frame or base. The first sensor can be a low-power proximity sensor, located on the front side of the display screen's frame or base. The motion information it detects specifically includes proximity signals to the area in front of the display component, environmental change signals, and a rough human presence signal. The second sensor can be a high-precision binocular camera module, located on the front side of the display screen's frame or base. The desktop area information it detects includes desktop object movement information such as keyboard movement signals, mouse movement signals, and movement signals of other desktop objects; user hand activity information includes user hand movement and dwell signals in the desktop area; user area information includes user proximity information such as main user proximity signals, bystander proximity signals, and bystander dwell signals; and main user presence information includes main user presence signals and main user departure signals. Compared to the first sensor, the second sensor has higher detection capabilities, detection accuracy, and power consumption.

[0023] The auxiliary controller receives motion and static information from the first sensor, controls the operation of the second sensor based on this information, and determines whether the system enters the detection mode. Furthermore, when the main controller is locked, it controls the operation of the display components and the main controller based on the desktop area and user area information from the second sensor. The main controller controls the operation of the display components based on the desktop area and user area information from the second sensor.

[0024] This embodiment also provides a control method for a display system, which is applied to the above-mentioned display system. Figure 1 A first flowchart of a control method for a display system provided in an embodiment of the present invention. As shown in Figure 1, the control method includes: S102 acquires the operating status of the display system, including a locked state where the display components, main control processor, and second sensor are all locked, and an unlocked state where the second sensor is running.

[0025] The auxiliary controller can receive the current operating status of the display components in real time, such as a locked state where the screen is black and in standby mode, or a working state where normal display operations are being performed. Simultaneously, the auxiliary controller can receive the current operating status of the main control processor in real time, such as a locked state where it is locked and in standby mode, or a working state where it is processing normally. Furthermore, the auxiliary controller can receive the current operating status of the second sensor in real time, such as a locked state where it is locked and in standby mode, or a normal detection state of the desktop area and user area. Specifically, when the display components, main control processor, and second sensor are all in a locked state, it indicates that the display system is not in a working state, and the display system is determined to be in a locked state. When the second sensor is in a normal operating detection state, it indicates that the display system and the user are in a dynamic working state, and the display system is determined to be in an unlocked state.

[0026] If the display system is locked, S104 enters a low-power detection mode. In the low-power detection mode, the following operations are performed: control the first sensor to collect dynamic and static information of the front area of ​​the display component; determine whether to exit the low-power detection mode and turn on the second sensor to enter the high-precision detection mode based on the dynamic and static information.

[0027] In the locked state, the display system is not in operation and enters a low-power detection mode. Only the low-power first sensor and auxiliary controller are activated to roughly collect dynamic information of the area in front of the display components, such as whether a user is approaching the detection area, environmental changes within the detection area (including objects and people), and a rough indication of the presence of a user. The first sensor feeds back the collected dynamic information to the auxiliary controller in real time. The auxiliary controller determines whether the display system is about to enter an operation state based on the received information and decides whether to continue in the current low-power detection mode or to turn off the first sensor to exit the low-power detection mode and activate the second sensor to unlock the display system. Then, it switches to a high-precision detection mode to accurately detect information in the area in front of the display components using the more precise second sensor, thereby improving the accuracy of the judgment of the display system's upcoming operation state.

[0028] If the display system is in an unlocked state, S106 enters the high-precision detection mode. In the high-precision detection mode, the following operations are performed: acquire the display information of the display component; control the second sensor to collect the desktop area information and user area information in front of the display component; and control the operation of the display component, the main processing controller, and the second sensor based on the display information, desktop area information, and user area information.

[0029] When dynamic changes occur within the detection area, indicating a potential change in the operating condition of the display system, the control system is unlocked. The auxiliary controller accordingly activates the second sensor and enters a high-precision detection mode. The display information includes whether the display component is currently operating, its brightness, the sensitivity of the displayed content, and the blurring / occlusion mode of the displayed content. The auxiliary controller receives this information in real time. Simultaneously, the second sensor collects information from the desktop area and user area in front of the display component. Desktop area information includes information on whether items on the desktop have moved and information on user hand movements on the desktop. User area information includes information on whether a user is approaching the display component and entering the detection area, and information on whether the main user is seated in the operating area.

[0030] Continuing, the auxiliary controller integrates desktop area information and user area information to determine the current operating condition and the upcoming operating condition of the display system. It determines whether the current display information of the display components matches the current and upcoming operating conditions, and accordingly adjusts the display information of the display components, the main processing controller, and the operating conditions of the second sensor to match the current and upcoming operating conditions of the display system. This improves the accuracy of identifying the current and upcoming operating conditions of the display system, and correspondingly improves the accuracy of adjusting the display components and the main control processor in terms of holding, waking up, locking, and display content processing, thereby improving the user experience. At the same time, based on the current and upcoming operating conditions of the display system, the on / off state of the second sensor is adjusted to ensure accurate detection of the desktop and user areas by the second sensor when the system is unlocked, and to reduce the high power consumption of the second sensor when the display system is locked.

[0031] The display system provided in this embodiment can execute the above control method. When the display system is in a locked state where it is not in operation and in an unlocked state where the operating conditions may change, different sensors are used to enter different detection modes. In the locked state, a low-power detection mode is entered, using a low-power first sensor and an auxiliary controller to achieve a rough detection of the dynamic and static information of the front area of ​​the display components with low power consumption, and to predict the operating conditions that the display system is about to enter. When unlocked, the system enters a high-precision detection mode, employing a second sensor to simultaneously and precisely detect dynamic information from both the desktop and user areas. By integrating information from both areas, the system accurately determines the current and upcoming operating conditions of the display system, and accordingly controls the operation of the display components and main control processor to match these conditions. This improves the accuracy of adjustments to the display components and main control processor in areas such as holding, waking up, locking, and processing display content, thereby enhancing the user experience. Simultaneously, based on the current and upcoming operating conditions of the display system, the system adjusts the on / off state of the second sensor to ensure accurate detection of the desktop and user areas when unlocked, and to reduce the high power consumption of the second sensor when the display system is locked. This achieves precise identification and control of the display system, improving the user experience while reducing power consumption and lowering costs.

[0032] Specifically, the display component can be a stand-alone smart all-in-one machine, a smart monitor, a conference terminal, or a desktop interactive terminal.

[0033] In this embodiment, the step S104, which determines whether to exit the low-power detection mode and enter the high-precision detection mode based on the motion and static information, includes: if the motion and static information is: a change from static (object is stationary and there is no user) to dynamic (object is moving or there is a user), then it is determined to exit the low-power detection mode and enter the high-precision detection mode.

[0034] In the locked state, there are no users in the detection area, and the items in the detection area, especially the desktop area, remain stationary. The first sensor continuously collects motion information of the detection area. When the motion information indicates that the detection area is static with no users and no items in sight, it indicates that the display system is still in a stable, inactive state, and the auxiliary controller controls the display system to maintain the current low-power detection mode. When a user approaches the display component and enters the detection area, or when items in the detection area move, the motion information indicates that the detection area has switched from a static state with no users and no items in sight to a dynamic state with items moving or users present. This indicates that the display system may be about to enter an active state, and the auxiliary controller determines to exit the current low-power detection mode and enter a high-precision detection mode. Accordingly, the auxiliary controller will control the first sensor to turn off and the second sensor to turn on to perform dual-area high-precision detection of the desktop area and the user area, thereby improving the accuracy of judging user intentions and the current and upcoming states of the display system, and improving detection accuracy.

[0035] In this embodiment, under high-precision detection mode, when both the display component and the main control processor are locked, step S106, which controls the operation of the display component, the main processing controller, and the second sensor based on the display information, desktop area information, and user area information, includes: if the user area information indicates that the main user is not present and the user proximity information indicates that a user is approaching; and if the desktop area information indicates that the desktop items remain stationary and the user hand activity information indicates no hand activity; then the display component is controlled to enter a pending confirmation state, and the main control processor is controlled to remain locked.

[0036] Both the display components and the main control processor are in a locked standby state, while the second sensor is in an activated detection state, indicating that the display system is currently in an inactive state. However, the detection area is dynamic, and the operating status of the display system may change. High-precision dual-area detection is performed using the second sensor. In the user area information, the presence information of the main user indicates that the main user is not at the table, but the user approach information indicates that a user has approached the desktop and entered the detection area. This suggests that there may be multiple scenarios, such as a user unintentionally approaching and entering the detection area while passing by, a user unintentionally entering the detection area, or the main user entering the detection area and about to use the display system. Simultaneously, in the desktop area information, the desktop object movement information indicates that the desktop objects remain stationary, and the user hand movement information indicates that there is no movement of the user's hand in the desktop area. If the user remains within the detection area, it is inferred that they are not using the keyboard, mouse, or other desktop devices. Based on the combined user area and desktop area information, it is determined that although a user has entered the detection area, they have not interacted with the mouse, keyboard, or other desktop devices. Therefore, the user's approach is considered invalid, and the display system remains inactive. The display components are then placed into a pending confirmation state, which may either maintain the current locked standby state or switch to a low-brightness display state. Simultaneously, the main control processor is not woken up, remaining locked until further determination of whether power-on is required. This reduces the likelihood of false wake-ups of the display components and main control processor upon the user entering the detection area, thereby improving control accuracy, enhancing the user experience, and reducing power consumption caused by false wake-ups.

[0037] In this embodiment, under high-precision detection mode, when both the display component and the main control processor are locked, step S106, which controls the operation of the display component, the main processing controller, and the second sensor based on the display information, desktop area information, and user area information, includes: if the user area information indicates that the main user is not present, and the user proximity information indicates that a user is approaching; and if the desktop area information indicates that a desktop object has moved, or the user's hand activity information indicates that a hand activity has occurred; then the display component and the main control processor are woken up to start working.

[0038] Both the display components and the main control processor are in a locked standby state, while the second sensor is in an activated detection state, indicating that the display system is currently in an inactive state. However, the detection area is dynamic, and the operating status of the display system may change. High-precision dual-area detection is performed using the second sensor. In the user area information, the presence information of the main user indicates that the main user is not at the table, but the user approach information indicates that a user has approached the desktop and entered the detection area. This suggests that there may be multiple scenarios, such as a user unintentionally approaching and entering the detection area while passing by, a user unintentionally entering the detection area, or the main user entering the detection area and about to use the display system. Simultaneously, the desktop area information includes at least desktop item movement information, indicating that desktop items... If movement or user hand activity information indicates that the user's hand is moving or lingering on the desktop area, it is inferred that the user is using items such as the keyboard or mouse on the desktop. Combining user area information and desktop area information, it is inferred that the user has entered the detection area and is operating the mouse or keyboard on the desktop. This is considered a valid approach, indicating the user is about to use the display system. The display system's operating status is about to switch to a working state (or remain inactive). The display components and main control processor are then activated, controlling the display components to enter the display working state and the main control processor to start operation. This ensures accurate judgment of the user's intention, guarantees the precision of activating the display components and main control processor, and improves the user experience.

[0039] In this embodiment, step S106, which controls the operation of the display component, the main processing controller, and the second sensor based on the display information, the desktop area information, and the user area information, includes: if the user area information shows that the main user is present and the user proximity information indicates that someone has entered the privacy area behind the main user; then determine whether the content displayed in the display information is sensitive content; if so, control the display component to blur the displayed content.

[0040] In high-precision detection mode, when the user area information indicates that the main user is sitting at a desk and working, the display component and main control processor are in operation, and the display component displays the content required by the main user. When both the main control processor and the auxiliary controller are operating, the main control processor is preferred for control processing. When a user approaches the detection area indicating that someone other than the main user has entered and is located in the privacy area behind the main user's seat, there is a possibility that the other person may be viewing the display content. Accordingly, the main control processor determines whether the current display content is sensitive. If the current display content is determined to be private, confidential, or confidential content that cannot be disclosed (i.e., sensitive content), the main control processor immediately controls the display component to blur the display content, thus obscuring the content to prevent privacy leaks and improve the security of the display system. If the current display content is determined to be publicly known and can be disclosed (i.e., non-sensitive content), the main control processor can control the brightness of the display component to decrease to remind the main user, or maintain the current operating state of the display component.

[0041] Of course, you can also reduce the brightness based on the sensitivity of the displayed content.

[0042] In this embodiment, under high-precision detection mode, when both the display component and the main control processor are working, step S106, which controls the operation of the display component, the main processing controller, and the second sensor based on the display information, desktop area information, and user area information, includes: if the user area information indicates that the main user is in place, meaning the main user has left their seat; and the desktop area information indicates that the desktop items are stationary, and the user's hand activity information indicates no hand activity; then the duration of the main user leaving their seat, the desktop items being stationary, and no hand activity is obtained; if the duration reaches a first preset duration, then the display mode of the display component is controlled according to the sensitivity of the displayed content in the display information.

[0043] In high-precision detection mode, when both the display component and the main control processor are working, the display component displays the content required by the main user. When the main user's presence information in the user area information indicates that the main user stands up and leaves the seat, it is inferred that there may be two situations: the main user leaves the seat for a short time and returns quickly, or the main user leaves the seat for a long time. At the same time, the desktop object movement information in the desktop area information indicates that the desktop objects have switched to a stationary state where they do not move, that is, the keyboard, mouse, etc. have switched to an inactive state, and the user's hand activity information indicates that there is no user hand activity in the desktop area. Combining the two, it is determined that the main user is no longer operating the items in the desktop area. Subsequently, the duration of the desktop objects being stationary and without hand activity after the main user leaves the seat is obtained from the above user area information and desktop area information. When the duration reaches a first preset duration, such as 2-4 minutes, it indicates that the main user does not need the display system to work temporarily. Accordingly, the display status of the display component is switched according to the sensitivity of the content displayed, so as to effectively protect the main user's privacy and reduce power consumption.

[0044] In this embodiment, the step of controlling the display mode of the display component according to the sensitivity of the displayed content in the display information includes: if the sensitivity of the displayed content is low, then the display component is controlled to display at low brightness to reduce power consumption; if the sensitivity of the displayed content is high, then the display component is controlled to blur the displayed content to effectively protect privacy and improve security. At this time, the display component can also be controlled to enter low brightness display to reduce power consumption.

[0045] In this embodiment, the control method further includes: if the duration reaches a second preset duration, then controlling the locking of the display component and the main control processor; wherein the second preset duration is longer than the first preset duration. When the main user leaves the seat according to the above user area information and desktop area information, and the desktop items remain still and there is no hand activity for a duration reaching the second preset duration, such as 5 to 10 minutes, it is determined that the main user has completely left and the display system is no longer needed for a short period of time. Accordingly, the display component and the main control processor are both controlled to enter a locked standby state, thereby reducing false locking, effectively protecting privacy, and reducing the power consumption of the display component and the main control processor.

[0046] In this embodiment, the control method further includes: if the duration reaches a third preset duration, controlling the second sensor to be turned off, exiting the high-precision detection mode, and entering the low-power detection mode; wherein, the third preset duration is longer than the second preset duration. When the duration of the main user leaving the seat and the desktop items remaining stationary without hand activity reaches the third preset duration, such as 15-20 minutes, it is determined that the main user no longer needs the display system to work for a long time, and the second sensor is turned off accordingly, stopping the high-precision, high-power detection of the detection area and exiting the high-precision detection mode; the first sensor is turned on again, entering the low-power detection mode, and the motion and stillness information of the detection area is detected through the first sensor, thereby reducing the power consumption of the second sensor while continuously detecting the detection area.

[0048] S201 controls the first sensor to collect motion and static information in the area in front of the display component. The motion and static information includes proximity signals, environmental change signals, and rough human presence signals.

[0049] S202 determines whether the dynamic information is: a change from static (object stationary and no user present) to dynamic (object moving or user present); if yes, proceed to step S203; if no, return to step S201.

[0050] S203 controls the first sensor to shut down, exiting the low-power detection mode, and turns on the second sensor to enter the high-precision detection mode.

[0051] S204 controls the second sensor to collect information from the desktop area and user area in front of the display component. The desktop area information includes information on the movement of desktop items and the user's hand movements. The user area information includes information on the user's proximity and the presence of the main user.

[0052] S205 controls the operation of the display components, main processing controller, and second sensor based on display information, desktop area information, and user area information.
