CONSTITUTION: A display device by using an organic electroluminescence device includes a first sub-pixel, a second sub-pixel and a third sub-pixel. The first sub-pixel is provided with a first switching device connected to each of the wiring, a first driving device connected to a plurality of transistor in parallel and a first luminance device connected to the first driving device. The second sub-pixel is provided with a second switching device connected to each of the wiring, a second driving device connected to a plurality of transistor in parallel and a second luminance device connected to the second driving device. And, the third sub-pixel is provided with a third switching device connected to each of the wiring, a third driving device connected to a plurality of transistor in parallel and a third luminance device connected to the third driving device.

Abstract: PURPOSE: A monitor, a computer main body, and a multi-user computer system using the wireless communication, and an operating method thereof are provided to make many users perform a computer process by connecting a server system and a client system through the wireless communication. CONSTITUTION: A carrier wave generator(130) generates a carrier wave allotted to the monitor. A data input tool(111) receives key input from a user. A wireless data transmitter(113) modulates the key input by the carrier wave and transmits the modulated key input wirelessly. A wireless signal receiver(124) demodulates the received A/V(Audio/Video) signal by the carrier wave. An A/V separator(125) separates the demodulated A/V signal into a video signal and an audio signal. A video output tool(121) outputs the video signal separated from the A/V separator. An audio output tool(122) outputs the audio signal separated from the A/V separator.
