METHOD OF PROVIDING ADDITIONAL INFORMATION ON EACH OBJECT WITHIN IMAGE BY DIGITAL INFORMATION DISPLAY DEVICE, DIGITAL INFORMATION DISPLAY DEVICE FOR THE SAME, AND VISIBLE LIGHT COMMUNICATION TERMINAL FOR RECEIVING ADDITIONAL INFORMATION
First Claim
1. A digital information display device for providing additional information on each object within an image, the digital information display device comprising:
- a display unit for outputting an image including at least one object;
a back light unit including a plurality of light sources located in a back surface of the display unit;
a controller for configuring a basic frame, the basic frame including all additional information on each object, and for allocating a transmission position for each object, the transmission position being a respective location in the basic frame where additional information on each object is respectively transmitted; and
a back light unit driver for controlling the back light unit such that the basic frame is transmitted in a visible light form through all of the plurality of light sources of the back light unit and the transmission position is transmitted through at least one light source corresponding to each object.

Abstract
A method and apparatus for providing additional information to a visible light communication terminal through visible light communication by an information display device having a back light unit is provided. The method includes, when the visible light communication terminal is located in one area corresponding to at least one additional information providing area that is disposed within a screen of the information display device, receiving time slot information allocated to the one area through the visible light communication, when the visible light communication terminal is located in remaining areas of the at least one area corresponding to the at least one object, except for the one area, receiving additional information on all objects from the remaining areas through the visible light communication, and acquiring additional information on the object corresponding to the one area from among the additional information on all the objects by using the allocated time slot information.

16. A method of providing additional information on each object within an image by a digital information display device, the method comprising:
-
outputting an image including at least one object; configuring a basic frame including all additional information on the at least one object; determining whether a visible light communication terminal is located in one area of at least one area illuminated through a light source of a back light unit, each of the at least one area respectively corresponding to one of the at least one object; when the visible light communication terminal is located in the one area, providing, in a visible light form, identification information identifying additional information corresponding to an object that corresponds to the one area by controlling flickering of a light source of the back light unit corresponding to the one area, the identification information being provided among all the additional information included in the basic frame; and transmitting, to visible light communication terminals located in the remaining areas, the basic frame by controlling flickering light sources of the back light unit, the flickering light sources corresponding to remaining areas except for the area corresponding to the one object. - View Dependent Claims (17, 18, 19, 20)
