For example, the user sets the target search range to 50cm.
  • the display device 200 After the display device 200 searches for the first Bluetooth device, only the device information of the first Bluetooth device with a communication distance less than or equal to 50cm is displayed; when the display device 200 receives the second Bluetooth device When the device sends a Bluetooth connection request, the Bluetooth connection request will be displayed only when the communication distance of the second Bluetooth device is less than or equal to 50cm, otherwise the Bluetooth connection request will not be displayed.
  • the user can simultaneously limit the first search range and the second search range of the display device 200 with only one setting, which can effectively simplify user operations.

Abstract

La présente demande concerne des dispositifs d'affichage, un procédé de recherche Bluetooth et un procédé de traitement de demande de connexion Bluetooth. Un utilisateur définit des premières plages de recherche d'un dispositif d'affichage, de sorte qu'après qu'un premier dispositif Bluetooth a été trouvé, seul un dispositif Bluetooth à sélectionner qui est parmi le ou les premiers dispositifs Bluetooth et est situé à l'intérieur d'une première plage de recherche cible soit affiché. Ainsi, le nombre de premiers dispositifs Bluetooth affichés est efficacement réduit et un utilisateur peut commodément reconnaître à partir de celui-ci un dispositif Bluetooth cible à connecter. Un utilisateur définit des secondes plages de recherche d'un dispositif d'affichage, de sorte que lorsqu'une demande de connexion Bluetooth envoyée par un second dispositif Bluetooth est reçue, la demande de connexion Bluetooth soit affichée uniquement lorsque le second dispositif Bluetooth est situé dans une seconde plage de recherche cible, permettant ainsi une sélection efficace de demandes de connexion Bluetooth affichées et réduisant en outre l'impact des demandes de connexion Bluetooth affichées sur l'utilisation normale du dispositif d'affichage par l'utilisateur et réduisant une menace pour la sécurité des données du dispositif d'affichage et la sécurité de la confidentialité de l'utilisateur.
