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

1 is a diagram illustrating a two-way telescreen apparatus using visible light communication according to the present embodiment.

The bidirectional telescreen apparatus 100 using visible light communication according to the present exemplary embodiment has a function of outputting an image and a function of receiving a visible light communications signal containing information.

Visible light communication is a communication technology that transmits information on light generated from light emitting elements such as light emitting diodes (LEDs) that are emitted by semiconductors. Light used in visible light communication has a wavelength of 380 nm to 780 nm. As the visible light, communication can be provided simultaneously with illumination. As a light emitting device for visible light communication, a light emitting diode (LED) for transmission and a photo diode for converting an optical signal into an electric signal are used for reception.

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

The screen 110 is a display device for outputting an image. In the present embodiment, the screen 110 is preferably implemented by using a light emitting diode (LED) capable of outputting a low power image, but is not necessarily limited thereto. The screen 110 may employ other elements or other display devices capable of outputting images in addition to the light emitting diodes (LEDs).

The screen 110 recognizes the position at which the visible light signal is irradiated when the visible light signal modulated based on the visible light communication technology is irradiated on the screen 110. This is similar to recognizing the position of a finger when touching the touch screen with a finger. The difference from the touch screen is that the visible light signal is used instead of the touch signal.

The screen 110 according to the present exemplary embodiment includes a plurality of photodiodes 114 for receiving a visible light signal together with a plurality of pixels 112 for outputting an image. The photodiode 114 is disposed in the space between the plurality of pixels 112.

The communication unit 120 transmits information about the visible light signal received from the screen 110 to the server. The communication unit 120 is implemented as a transceiver using communication technologies such as radio frequency, ultra wideband (UWB), wireless LAN (WIFI), and Zigbee.

The controller 130 converts the image signal received from the communication unit 120 into a signal for directly driving the pixels 112. That is, the controller 130 controls the control signal for each pixel 112 included in the screen 110 so that the image information included in the image signal received from the communication unit 120 can be output to the screen 110. Create If the pixels 112 are implemented as light emitting diodes (LEDs), 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 be divided into a main controller and an auxiliary controller according to the number of pixels 112 and the size of the resolution to perform signal conversion step by step.

A speaker (not shown) is a device that receives sound signals from the communication unit 120 and converts them into sound waves so that viewers can hear sound and is attached to one side of the screen 110.

Therefore, the portable visible light transmitting apparatus 200 according to the present embodiment plays a role similar to that of a finger or a computer mouse using a touch screen.

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

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

The push button 220 generates, for example, an information signal including information about selection or non-selection and includes the information signal in the above-described optical signal. This is similar to the function of the click button of the mouse. When the push button 220 is pressed by the user's finger, a selection signal corresponding to 'selection' is transmitted to the screen 110 through the transmitter 210.

The microchip (not shown) is a small chip provided in the portable visible light transmitter 200 and receives data in the smartphone terminal 240, tablet or laptop connected through the cable 230 to the transmitter 210. Control the process of transmission.
