Abstract: A refrigerator includes a cabinet, a door, a transparent panel assembly disposed at the door and defining a see-through part through which an interior of the refrigerator is visible, and a first light disposed closer to the interior than the transparent panel assembly to brighten an area viewed by the see-through part. The transparent panel assembly includes transparent panels spaced apart from each other to define an accommodation space, a display disposed in the accommodation space to output a screen, and a second light brightening the display. The display, the first light, and the second light are selectively turned off according to manipulation of a user to be converted into an opaque state in which the interior is not visible and a transparent state in which the interior is visible, and in the transparent state, a screen is outputted while an inner space of the refrigerator is seen.

Abstract: Provided is an artificial intelligence refrigerator. The artificial intelligence refrigerator includes a cabinet defining a storage space, a door opening and closing the cabinet, a transparent display assembly which covers an opened see-through part of the door and through which an inner space of the artificial intelligence refrigerator is seen, and a screen is outputted, a display PCB controlling an operation of the transparent display assembly, a voice recognition unit connected to the display PCB to process a user's voice signal, and a microphone connected to the voice recognition unit. The display PCB outputs output screens of the transparent display assembly in stages according to a processing state of the voice signal when a user's voice is inputted.

Abstract: A network system is provided. The network system includes: a first component having a first device code and performing a predetermined function; and a second component having a second device code and exchanging information with the first component for communication connection. One of the first and second components receives a command for the communication connection and generates a connection sequence. The component generating the connection sequence exchanges communication addresses and device codes with the other component receiving the connection sequence. If the information has not been exchanged between the first component and the second component during a predetermined time, the first component and the second component are switched to a communication connection standby mode.
