Abstract:
1. An organic light emitting diode (OLED) display device for visible ray communication, comprising: a substrate; a plurality of OLED pixels that are formed on the substrate and generate a red (R), green (G), or blue (B) visible ray; a plurality of light receiving units that are formed on the substrate to sense a visible ray signal and convert the visible ray signal to an electrical signal; and a control unit that controls the plurality of OLED pixels to display an image on a screen formed of the plurality of OLED pixels and receives a visible ray signal that is received by the plurality of light receiving units, wherein together when receiving the visible ray signal, the control unit detects a position of each of the light receiving units on a screen at which the visible ray signal is received, coordinates of the light receiving units on the screen corresponding to identification numbers of the light receiving units are stored in the control unit in advance, and the light receiving units transmit the identification numbers to the control unit, together with the received visible ray signal.
