The display system includes a user terminal device, the display device and a server. The display device obtains location information and a user identification code according to an ultra-wideband signal. The display device determines whether the location information matches a preset condition. The display device sends a verification request signal including the user identification code to the server. The server receives the verification request signal and executes a verification process to verify the user identification code to generate a verification result. The server sends the verification result to the display device. A screen of the display device is unlocked. ## Claims ### Claim 1 An unlocking method, adapted for a display system, the display system comprising a display device, a server and a user terminal device, wherein the display device is communicatively connected to the server, the method comprising: via the user terminal device, continuously transmitting an ultra wideband signal; via the display device, in response to receiving the ultra wideband signal, and obtaining location information of the user terminal device and the display device and a user identification code based on the ultra wideband signal; via the display device, in response to the location information matching a preset condition, sending a verification request signal containing the user identification code to the server; via the server, in response to receiving the verification request signal, performing a verification process on the user identification code and generating a verification result; via the server, transmitting the verification result to the display device, wherein the verification result is configured to indicate whether the user identification code is correct; and via the display device, in response to receiving the verification result, unlocking a screen of the display device. ### Claim 2 (depends on 1) The unlocking method of claim 1, further comprising: via the display device, in response to the verification result, sending a user data request signal to the server, wherein the verification result represents that the user identification code is correct; via the server, in response to receiving the user data request signal, sending user data corresponding to the user identification code to the display device; via the display device, in response to receiving the user data, and performing a personalized setting according to the user data; and via the display device, after the personalized setting is completed, unlocking the screen of the display device. ### Claim 3 (depends on 1) The unlocking method of claim 1, wherein the preset condition comprises: a distance between the user terminal device and the display device is less than 50 centimeters; and the user terminal device is located within a range of 0-180 degrees in front of the display device. ### Claim 4 (depends on 1) The unlocking method of claim 1, wherein the location information comprises: a distance between the user terminal device and the display device; and an angle of the user terminal device relative to the display device. ### Claim 5 (depends on 1) The unlocking method of claim 1, the method further comprising: via the user terminal device, executing an interactive application;
