[0055] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0056] The display device wake-up method of the present application can be applied to Figure 1 In the application environment shown. Among them, multiple display devices 100 communicate through a wired or wireless network. In actual applications, the display devices can be, but are not limited to, televisions, advertising machines, laptops, etc. in the same space, and the network can be a LAN (local area network), which is usually a network system distributed in a limited geographical range, including a star network, a tree network, a bus network, a ring network, etc., which is not limited in the present invention.

[0057] For example, Figure 2 As shown, a display device wake-up method is provided, which is applied to a control unit of the display device 100, the control unit communicates with a millimeter wave radar sensor disposed on the display device 100, and the millimeter wave radar sensor collects real-time location information of a person. The method includes the following steps:

[0058] Step 101, obtaining first real-time location information of a person and broadcasting it in a local area network.

[0059] In actual applications, the real-time location information of a person can be collected by a millimeter-wave radar sensor installed on the display device. The real-time location information can be collected by collecting the location information of the person at a certain time interval, such as collecting the distance information of the person relative to the display device every 1 second or 2 seconds. The specific form of expression can be the first distance information between the person and the current display device.

[0060] After the first real-time location information is acquired, the first real-time location information is broadcast externally through the local area network.

[0061] Step 102: Receive second real-time location information broadcasted by other display devices in the local area network.

[0062] Other display devices in the local area network will also obtain the real-time location information of the person and broadcast it to the outside through the local area network. Here, the real-time location information of the person obtained by all other display devices is collectively referred to as the second real-time location information. The second real-time location information can be the second distance information between the person and the other display devices. The current display device will receive the second real-time location information broadcast by other display devices in the local area network.

[0063] Step 103, judging whether the first real-time location information meets the preset wake-up condition according to the first real-time location information and the second real-time location information, if the judgment result is yes, proceed to step 104, if the judgment result is no, proceed to step 105.

[0064] The preset wake-up condition is used to selectively wake up some display devices when a wake-up voice is received. The first distance can be the smallest of all distances, or the first distance can be several smallest distances. The specific number of settings can be determined by controlling the proportion of the number. For example, when there are 10 display devices, the wake-up condition can be preset to 30% of the smallest distance, then the 3 with the smallest distance meet the preset wake-up condition.

[0065] Step 104: When it is determined that the first real-time location information meets the preset wake-up condition and a wake-up voice is received, the display device is woken up.

[0066] Step 105: When it is determined that the first real-time location information does not meet the preset wake-up condition, but a wake-up voice is received, the display device is controlled not to be woken up.

[0067] The above display screen control method can obtain the first real-time position information of the person relative to the current display device and the second real-time position information of the person relative to other display devices, and then predict whether the current display device belongs to the object that the user wants to wake up based on the first real-time position information and the second real-time position information and the preset wake-up condition. When the current display device meets the preset wake-up condition and receives the wake-up voice, the display device is woken up; when the current display device does not meet the preset wake-up condition but receives the wake-up voice, the display device is controlled not to be woken up. By conditionally controlling the display device awakened by the wake-up voice through the preset wake-up condition, the wake-up is more accurate and the problem of false awakening is avoided.

[0068] Exemplary, reference Figure 3 In a display screen control method provided by the present invention, when it is determined that the first real-time location information meets the preset wake-up condition and a wake-up voice is received, the process of waking up the display device includes the following steps 201 and 202; when it is determined that the first real-time location information does not meet the preset wake-up condition, but a wake-up voice is received, the process of not waking up the display device includes the following steps 203 and 204.

[0069] Step 201: When it is determined that the first real-time location information meets a preset wake-up condition, the state of the display device is set to allow voice wake-up.

[0070] Step 202: When a wake-up voice is received, wake up the display device.

[0071] Step 203: When it is determined that the first real-time location information does not meet the preset wake-up condition, the state of the display device is set to not allowing voice wake-up.

[0072] Step 204: When the wake-up voice is received, the display device is not woken up.

[0073] In the above method, the judgment process of whether the current display device meets the preset wake-up conditions is carried out in real time. When it is judged that the corresponding conditions are met, the state of the display device is adjusted to a state that allows voice wake-up. In this state, when the wake-up voice is received, there is no need to go through the more complicated judgment process of whether the preset wake-up conditions are met, and the display device can be directly woken up. Similarly, when it is judged that the corresponding conditions are not met, the state of the display device is adjusted to a state that does not allow voice wake-up. In this state, when the wake-up voice is received, there is no need to go through the more complicated judgment process of whether the preset wake-up conditions are met, and the display device is directly kept in a non-awakened state. It can be seen that the above method is timely and efficient, and the user experience is good. At the same time, the method can also effectively prevent the current display device from being disconnected from the local area network when the wake-up voice is received, making it impossible to judge whether the conditions are met.

[0074] Exemplary, reference Figure 4 In a display device wake-up method provided by the present invention, the display device includes a database, and the database is used to store the current minimum distance. According to the first real-time location information and the second real-time location information, the process of determining whether the first real-time location information meets the preset wake-up condition includes the following steps:

[0075] Step 301, when the first distance is obtained, it is determined whether the first distance is less than the current minimum distance. If the determination result is yes, the current minimum distance is replaced by the first distance, and it is determined that the first distance meets the preset wake-up condition.

[0076] Step 302, when the second distance is obtained, it is determined whether the second distance is less than the current minimum distance. If the determination result is yes, the current minimum distance is replaced by the second distance, and it is determined that the first distance does not meet the preset wake-up condition.

[0077] In actual applications, the current minimum distance field in the initial database is empty. After a test to see if the preset wake-up condition is met, the current minimum distance field is updated to the current minimum distance value. Subsequently, each time the second distance is obtained, it is compared with the current minimum distance value. If the second distance is less than the current minimum distance value, it indicates that the current display device is not the device closest to the person, and the second distance is updated to the current minimum distance value. If the second distance is greater than the current minimum distance value, it indicates that the current display device is the device closest to the person, and the current minimum distance field is not changed. Each time the first distance is obtained, it is directly compared with the current minimum distance value. If the first distance is less than the current minimum distance value, it indicates that the current display device is the device closest to the person, and the first distance is updated to the current minimum distance value, and it is determined that the preset wake-up condition is met. If the first distance is greater than the current minimum distance value, it indicates that the current display device is not the device closest to the person, and the current minimum distance field is not changed, and it is determined that the preset wake-up condition is not met.

[0078] In actual applications, some objects may be mistakenly identified as people, thereby executing related judgment processes and causing miscontrol. For example, refer to Figure 5 The display device wake-up method provided by the present invention further includes the following steps:

[0079] Step 401, determining whether there is a living body within a preset area.

[0080] The preset area range may be pre-built into the display device, or may be determined based on monitoring of the environment in which the display device is located. The specific form of the range may be a distance value, such as a fixed value of 3 meters, 5 meters, 7.5 meters, etc., or the distance from the display device to the opposite wall determined based on the environment in which the display device is located.

[0081] The display device is provided with an ultrasonic ranging module, which controls the speaker of the display device to continuously emit 20-22KHz ultrasonic waves. The TV microphone receives the ultrasonic signals reflected back by obstacles. The collected ultrasonic signals can be processed to calculate the relative positions of obstacles within the preset area. Since living bodies are not absolutely still, they will shake when standing, and at least there will be vibrations on the skin surface caused by breathing and heartbeat, so the relative positions of obstacles are fluctuating. In this case, it can be determined that there is a living body, otherwise, it is determined that there is no living body.

[0082] When it is determined that the first real-time location information meets the preset wake-up condition and a wake-up voice is received, the step of waking up the display device includes the following steps:

[0083] Step 402, when it is determined that the first real-time location information meets the preset wake-up condition, there is a living body within the preset area, and a wake-up voice is received, the display device is woken up.

[0084] The above method, on the basis of judging that the first real-time location information meets the preset wake-up conditions, adds the condition that there is a living body within the preset area, so that the display device can be woken up when the wake-up voice is received. The display device can be woken up more accurately according to the user's needs and the occurrence of miscontrol can be reduced.

[0085] Exemplary, reference Figure 6 In a display device wake-up method provided by the present invention, when the real-time position information of an obstacle changes, the process of determining whether there is a person within a preset area includes the following steps:

[0086] Step 501, when the real-time position information of the obstacle changes, determine whether the current distance of the obstacle from the display device is within a preset distance range based on the real-time position information of the obstacle. If the judgment result is yes, proceed to step 502, if the judgment result is no, proceed to step 503.

[0087] Step 502: If the judgment result is yes, it is determined that there is a person within the preset area.

[0088] Step 503: If the judgment result is no, it is determined that there is no person within the preset area.

[0089] The preset distance range can be determined according to the size of the venue, the distance to obstacles and walls in front, etc., and can be specifically expressed as a distance value, such as 5 meters, 7 meters, etc.

[0090] In the above method, when it is determined that the current distance of the obstacle from the display device is not within the preset distance range, regardless of whether the real-time position information of the obstacle changes, it is determined that there is no person present, and people at a farther distance can be excluded to ensure the accuracy of the wake-up result.

[0091] For example, Figure 7 As shown, a display device wake-up device is provided, comprising: a first real-time location information acquisition module 601, a second real-time location information receiving module 602, a to-be-wake-up condition judgment module 603, a wake-up module 604 and a non-wake-up module 605, wherein:

[0092] The first real-time location information acquisition module 601 is used to acquire the first real-time location information of a person and broadcast it in the local area network.

[0093] The second real-time location information receiving module 602 is used to receive the second real-time location information broadcasted by other display devices in the local area network.

[0094] The wake-up condition judgment module 603 is used to judge whether the first real-time location information meets the preset wake-up condition according to the first real-time location information and the second real-time location information;

[0095] The wake-up module 604 is used to wake up the display device when it is determined that the first real-time location information meets the preset wake-up condition and a wake-up voice is received.

[0096] The non-awakening module 605 controls the display device not to be awakened when it is determined that the first real-time location information does not meet the preset awakening condition but a wake-up voice is received.
