Hereinafter, the present embodiment will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a bidirectional telescreen device using visible light communication according to an embodiment of the present invention.

The bidirectional telescreen device 100 using the visible light communication according to the present embodiment has a function of outputting a video object and a function of receiving a visible light communication signal containing information.

Visible light communication is a communication technology in which light from a light emitting element such as a light emitting diode that emits light by a semiconductor is used as a carrier wave, and information is transmitted thereon. The light used in visible light communication is a visible light having a wavelength of 380 nm to 780 nm and, by its nature, can provide communication simultaneously with illumination. As a light emitting element for visible light communication, a light emitting diode (LED) is used for transmission, and a photo diode (photo diode) for converting an optical signal into an electric signal is used for reception.

The bidirectional telescreen device 100 using visible light communication according to the present embodiment includes a screen 110, a communication unit 120, a control unit 130, and a speaker (not shown).

The screen 110 is a display device for outputting an image. In the present embodiment, it is preferable to employ a light emitting diode (LED) capable of outputting a low-power image. However, the present invention is not limited thereto. Another display device capable of performing other display operations may be employed.

The screen 110 recognizes the position where the visible light signal is irradiated when the modulated visible light signal is irradiated onto the screen 110 based on the visible light communication technique. This is similar to recognizing the position of a finger when touching the touch screen with a finger. Unlike a touch screen, it uses a visible light signal instead of a touch screen.

Therefore, the screen 110 according to the present embodiment is implemented by including a plurality of photodiodes 114 for receiving visible light signals, together with a plurality of pixels 112 for image output. The photodiode 114 is disposed in a space between the plurality of pixels 112.

Referring to FIG. 1, a plurality of pixels 112 are grouped into a unit module 113 and a photodiode 114 is disposed in a space between the unit modules 113. However, the present invention is not limited thereto, and the photodiode 114 may be implemented by being disposed in the space between the individual pixels 112.

Although not shown in the drawing, the screen 110 may have various functions such as a filter circuit for detecting a signal including information carried on a carrier wave, a demodulating circuit, and the like, from a visible light signal received by the photodiode 114 . These circuits are well known in the art and will not be described here.

The communication unit 120 receives a video signal for output to the screen 110 from the server. The communication unit 120 also transmits information on the visible light signal received from the screen 110 to the server. The communication unit 120 is implemented as a transceiver using a communication technology such as a radio frequency, an ultra wideband (UWB), a wireless LAN (WIFI), and a Zigbee.

The control unit 130 converts the pixels 112 into signals for directly driving the pixels 112 using the video signals received from the communication unit 120. [ If the pixels 112 are implemented as a light emitting diode (LED), the controller 120 converts the received image signal into a light emitting diode control signal capable of directly driving the light emitting diodes. Here, the controller 130 may divide the main controller into the main controller and the auxiliary controller according to the number of the pixels 112 and the size of the resolution, and perform signal conversion step by step.

A speaker (not shown) is attached to one side of the screen 110 as a device for receiving an acoustic signal from the communication unit 120 and converting the electric signal into a sound wave so that the viewer can hear the sound.

2A and 2B are views showing a portable visible light transmitting apparatus according to the present embodiment.

2A, the portable visible light transmitting apparatus 200 according to the present embodiment is intended to transmit visible light to the bidirectional telescreen apparatus 100 using visible light communication and transmit the visible light through the visible light signal receiving coordinates of the screen 110 Information is transmitted. Therefore, the portable visible light transmitting apparatus 200 according to the present embodiment plays a role similar to a finger using a touch screen or a mouse of a computer.

2B, the portable visible light transmitting apparatus 200 according to the present embodiment includes a transmitting unit 210, a push button 220, a microchip (not shown), and a cable 230.

The transmitting unit 210 converts an electric signal into a visible light signal to irradiate the visible light signal to the bidirectional telescreen device 100 using visible light communication. The transmitting unit 210 includes a light emitting diode (LED) for emitting an optical signal as an apparatus for generating an optical signal. A circuit configuration such as a modulation circuit for modulating a signal using a carrier of a specific frequency is required in the transmitter 210, and a detailed description of these circuits will be omitted.

The push button 220 serves to generate an information signal, for example, Yes / No, and to include the information signal in the above-described optical signal. This is similar to the function of a click button of a mouse. When the push button 220 is pressed by the user's finger, a 'yes' signal is transmitted to the screen 110 through the transmitter 210.

A microchip (not shown) is a small chip provided inside a portable visible light transmitting apparatus 200 and receives data from a smartphone terminal 240, an iPad or a laptop connected through a cable 230, As shown in FIG.

The cable 230 is a connection cable for linking the portable visible light transmitting apparatus 200 according to the present embodiment with a user's smartphone terminal 240, an iPad (not shown) or a laptop (not shown) (Universal Serial Bus) or micro USB.

When the cable 230 is connected to the smartphone terminal 240, the iPad or the laptop, the user converts the data of the smartphone terminal 240, the iPad or the laptop into the visible light signal through the portable visible light transmitting device 200 To the bi-directional telescreen device 100 using visible light communication.

Details of the tour guide service provided by the tour guide server 310 will be described later in detail with reference to FIG. 4. Hereinafter, the function of the tour guide server 310 will be briefly described.

The tour guide server 310 transmits the wireless data signal to the tourist smartphone terminal 240 or the personal computer terminal 320 before or during the travel. This data signal includes tourist information to assist travelers in finding and reserving tourist goods and a guide to a list of waypoints around the travel route.

When the traveler is traveling, the tourist information server 310 transmits the wireless data signal to the smartphone terminal 240 carried by the traveler. If a two-way telescreen device 100 installed in a train, a bus, or a bus around a travel destination receives a visible light signal transmitted from a portable visible light transmitting device 200 carried by a traveler during a trip, The apparatus 100 connects to the tour guide server 310 and the tour guide server 310 transmits the wireless data signals to the above-described two-way telescreen apparatus 100. [ This data signal provides an itinerary map service that includes a guide to the route list around the travel route and the travel route, and also provides a prizewinning event to the traveler. A description of the itinerary map service will be described later with reference to FIG.

After the end of the trip, the tourist information server 310 generates data for helping travel report creation based on the destination arrival information of the traveler received from the bidirectional telescreen device 100 or the smartphone terminal 240, (320).
