Display tag, display tag system having display tag, and method for writing display tag information

Abstract

A display tag is provided. A display tag includes a sensing unit which captures an image displayed on a screen of an external tag writer, if a sensing unit is disposed opposite the screen; and a display unit which displays a captured image. Therefore, a user can visually recognize content related to tag information, and thus user convenience is enhanced.

What is claimed is: 
     
         1 . A method for controlling a display device having a tag writing area, comprising:
 receiving a user selection of at least one image among displayed images on the display device;   detecting whether a mobile device contacts the tag writing area of the display device ; and   transmitting information corresponding to the selected image,   wherein the tag writing area is at least one part of the display device.   
     
     
         2 . The method of  claim 1 , wherein the display device comprises a tag information storage unit which stores tag information regarding the selected image,
 wherein the transmitting comprises, when the mobile device is detected to be in contact with the tag writing area of the display device, transmitting information corresponding to the selected image which is pre-stored in the tag information storage unit to the mobile device.   
     
     
         3 . The method of  claim 1 , wherein the transmitting comprises, when the mobile device is detected to be in contact with the tag writing area of the display device, transmitting the selected image along with the information. 
     
     
         4 . A method for controlling a display device having a tag writing area, comprising:
 displaying a plurality of images on a portion of the display device;   receiving user selection of at least one image among the plurality of images; and   displaying a image corresponding to the selected image on the tag writing area of the display device,   wherein the portion of the display device is different from the tag writing area.   
     
     
         5 . The method of  claim 4 , further comprising:
 when an image displayed on the tag writing area is captured by a mobile device, transmitting information corresponding to the captured image to the mobile device.   
     
     
         6 . A method for controlling a mobile device, comprising:
 detecting whether the mobile device is disposed opposite a tag writing area of a display device;   automatically capturing at least one image displayed on the tag writing area corresponding to the detection; and   displaying the captured image on the mobile device.   
     
     
         7 . The method of  claim 6 , further comprising,
 receiving information corresponding to the captured image from the display device.   
     
     
         8 . The method of  claim 6 , wherein the displaying comprises the captured image on an opposite side of one side of the mobile device which is disposed opposite to the tag writing area. 
     
     
         9 . The method of  claim 6 , wherein the mobile device comprises a sensing unit which captures an image on one side of the mobile device and comprises a display unit which displays the captured image on an opposite side of one side of the mobile device having the sensing unit. 
     
     
         10 . A method for transmitting tag information of a display device, comprising:
 receiving a user selection of at least one image among displayed images;   receiving user command for moving the selected image from a original display position to a tag writing area;   moving the selected image from the original display position to the tag writing area; and   transmitting tag information corresponding to the selected image if the selected image is moved,   wherein the user command is drag and drop interaction.   
     
     
         11 . The method of  claim 10 , wherein the transmitting comprises, when a mobile device is disposed opposite to the tag writing area of the display device, transmitting the tag information to the mobile device. 
     
     
         12 . The method of  claim 10 , wherein the display apparatus comprises a tag information storage unit which stores tag information regarding the selected image,
 wherein the transmitting comprises, when a mobile device is disposed opposite to the tag writing area of the display device, transmitting tag information corresponding to a selected image which is pre-stored in the tag information storage unit to the mobile device.   
     
     
         13 . The method of  claim 10 , wherein the transmitting comprises, when a mobile device is disposed opposite to the tag writing area of the display device, transmitting the selected image along with the information.
