Abstract

A display device includes a display; a memory storing at least one instruction; a communicator configured to communicate with a mobile device via a BLE communication network; and a controller including a processor configured to execute the at least one instruction stored in the memory. The processor is further configured to execute the at least one instruction to manage BLE identification information when the BLE identification information for identifying the mobile device connected via the BLE communication network is received from the mobile device during a normal mode in which an ambient service is being executed, and the communicator is further configured to, based on the BLE identification information received from the mobile device after a sleep mode is started, determine whether to wake up the controller based on whether information corresponding to the BLE identification information is stored in the communicator.

First claim

What is claimed is:

1. A display device comprising:
a display;
a memory storing at least one instruction;
a communicator configured to communicate with a mobile device via at least one wireless network comprising a Bluetooth low energy (BLE) communication network, and receive BLE identification information for identifying the mobile device, from the mobile device; and
a controller comprising at least one processor configured to execute the at least one instruction to:
control identification information to be respectively stored in both the memory and a dedicated memory so that the identification information stored in the memory is the same as the identification information stored in the dedicated memory for the communicator, and
based on the receiving, by the communicator, the BLE identification information from the mobile device while the display device operates in a normal mode in which a service for displaying a screen image on the display is being executed, determine whether a registered mobile device is present based on whether identification information corresponding to the BLE identification information received from the mobile device is stored in the memory,

wherein, based on the receiving, by the communicator, the BLE identification information from the mobile device while the display device operates in a sleep mode, the communicator is further configured to determine whether to wake up the controller based on whether identification information corresponding to the BLE identification information received from the mobile device is stored in the dedicated memory for the communicator that is different from the memory.

2. The display device of claim 1 , wherein the communicator is further configured to wake up the controller based on the identification information corresponding to the BLE identification information being present in the dedicated memory.

3. The display device of claim 1 , wherein the communicator is further configured to maintain the sleep mode of the controller based on the identification information corresponding to the BLE identification information not being present in the dedicated memory.

4. The display device of claim 1 , wherein the at least one processor is further configured to execute, in the normal mode, the at least one instruction to receive the BLE identification information from the communicator, determine whether the identification information corresponding to the BLE identification information is present in the memory, and determine whether to maintain the executing the service, based on a result of the determining.

5. The display device of claim 1 , wherein the memory comprises a first memory and a second memory, and
the at least one processor is further configured to execute the at least one instruction to control the BLE identification information of the mobile device to be stored in the first memory and the dedicated memory of the communicator based on the BLE identification information received from the mobile device in the normal mode, and when the normal mode is started, load, into the second memory, a program corresponding to a first application for executing the service, and control the first application to be executed.

6. The display device of claim 1 , wherein the mobile device is a first mobile device having a first BLE identification information stored as the identification information in the memory, and
the at least one processor is further configured to execute the at least one instruction to:
receive a second BLE identification information from a second mobile device to be paired with the display device, to register the second mobile device, and
store the second BLE identification information in the memory and the dedicated memory of the communicator.

7. The display device of claim 1 , wherein the sleep mode comprises an operation mode in which the service is stopped and then the display is turned off.

8. The display device of claim 1 , wherein the at least one processor is further configured to execute the at least one instruction to control the BLE identification information to be stored in the memory, the BLE identification information being transmitted from the mobile device paired with the display device for execution of the service, and determine, by using, the BLE identification information, whether the mobile device is positioned within a predetermined distance from the display device.

9. The display device of claim 1 , wherein the BLE identification information comprises a BLE media access control (MAC) address of the mobile device or a random address of the mobile device, the random address being convertible to the BLE MAC address by using an Identity Resolving Key (IRK).

10. The display device of claim 1 , wherein the at least one processor is further configured to execute the at least one instruction to differently set a scheme of identifying the mobile device based on an operating system (OS) of the mobile device registered in the display device.

11. A display device comprising:
a display;
a memory storing at least one instruction;
a communicator configured to communicate with a mobile device via at least one wireless network comprising a Bluetooth low energy (BLE) communication network; and
a controller comprising at least one processor configured to execute the at least one instruction stored in the memory,
wherein, based on receiving BLE identification information for identifying the mobile device from the mobile device via the BLE communication network while the display device operates in a normal mode in which a service for displaying a screen image on the display is being executed, the at least one processor is further configured to execute the at least one instruction to determine whether a registered mobile device is present based on whether information corresponding to the BLE identification information received from the mobile device is stored in the memory,
based on receiving the BLE identification information from the mobile device while the display device operates in a sleep mode, the communicator is further configured to determine whether to wake up the controller based on whether the information corresponding to the BLE identification information is stored in the communicator, and
the at least one processor is further configured to execute the at least one instruction to differently set a scheme of identifying the mobile device, according to whether an operating system (OS) of the mobile device registered in the display device is a first OS or a second OS.

12. The display device of claim 11 , wherein the first OS is an Android OS and the second OS is an iOS.

13. The display device of claim 11 , wherein the mobile device is registered in the display device and the OS of the mobile device is the first OS, and
the at least one processor is further configured to execute the at least one instruction to control the communicator to check reception of the BLE identification information at certain time intervals.

14. The display device of claim 11 , wherein the mobile device is registered in the display device and the OS of the mobile device is the second OS, and
the at least one processor is further configured to execute the at least one instruction to control the communicator to transmit, at certain time intervals, a first iBeacon signal for requesting transmission of the BLE identification information to the mobile device, and
check reception of a second iBeacon signal triggered by the first iBeacon signal and comprising the BLE identification information.

15. A control method of a display device, the control method comprisi
