Description

CROSS-REFERENCE TO RELATED APPLICATION(S) This application is the National Stage filing under 35 U.S.C. 371 of International Application No. PCT/KR2022/007076, filed on May 17, 2022, the contents of which are all incorporated by reference herein in its entirety. TECHNICAL FIELD The present disclosure relates to a display device. More specifically, the present disclosure relates to a display device that automatically recognizes and sets a connected external device. BACKGROUND ART Digital TV services using wired or wireless communication networks are becoming common. The digital TV services may provide various services that cannot be provided by existing analog broadcasting services. For example, in the case of IPTV (Internet Protocol Television) and smart TV services, which are types of digital TV services, interactivity is provided so that users can actively select the types of programs to watch, the viewing time, and the like. IPTV and smart TV services may provide various additional services, such as Internet search, home shopping, online games, etc., based on such interactivity. And recently, the number of users who watch more diverse videos through external devices such as set-top boxes and DVD players, not limited to the videos provided by the display device itself, is increasing. Accordingly, display devices provide various functions for the convenience of users when connected to an external devices, and for example, provide an integrated remote control function. The integrated remote control function is a function that allows multiple devices to be controlled with only one remote control. Meanwhile, in order to provide various functions such as the integrated remote control function, settings suitable for the external device connected to the display device are required, so information about the device is required so that the external device can be identified. Accordingly, the display device can manually input information about the external device or automatically recognize the external device. In the past, when the external device was connected, the display device recognized the external device based on the information received from the external device. However, since each external device arbitrarily transmits information to the display device, information can be transmitted through various paths and at various times, and the types or orders of the transmitted information are all different, problems of incorrectly recognizing the external device occur during this process. In addition, even if an external device is recognized incorrectly in this way, there is no function to verify or correct it, which causes inconvenience to the user. DISCLOSURE Technical Problem The purpose of this present disclosure is to provide a display device that minimizes problems caused by misrecognition of an external device. The purpose of this present disclosure is to provide a display device that performs re-recognition when an external device is misrecognized. Technical Solution The display device according to an embodiment of present disclosure comprises a display, an external device interface configured to connect to an external device, and a controller configured to recognize a device corresponding to information received from the external device and set the recognized device as a connection device through the external device interface, wherein the controller is configured to recognize a device corresponding to each of the plurality of pieces of information when receiving a plurality of pieces of information from the external device, calculate a recognition accuracy of a device corresponding to each of the plurality of pieces of information, and set a recognized device corresponding to one of the plurality of pieces of information as the connection device based on the calculated recognition accuracy. The controller is configured to set a device with a highest recognition accuracy among the recognized devices as the connection device when there are a plurality of recognized devices corresponding to each of the plurality of pieces of information. The controller is configured to, when receiving first information and second information from the external device and recognizing a first device and a second device corresponding to the first information and the second information, respectively, set a device corresponding to a higher recognition accuracy among a recognition accuracy of the first device and a recognition accuracy of the second device as the connection device. The controller is configured to display a screen for receiving a selection for one of the first device and the second device on the display when the recognition accuracy of the first device and the recognition accuracy of the second device are the same. The controller is configured to, when there are a plurality of devices recognized corresponding to each of the plurality of pieces of information, set a device whose recognition accuracy is calculated to be
