Abstract
A multi-functional monitor includes a plurality of availability of mature circuits, including a TV signal processing circuit, a signal amplifying circuit, a H/V deflection circuit, a CRT display tube, an AV switching circuit, a video and audio output/input circuit, and a FM radio receiver. The multi-functional monitor further includes the following newly designed circuits to incorporate with the above mature circuits, including a switcher A, a switcher B, a micro controller unit, a TV flyback pulse simulating circuit, and an integrated control circuit. The multi-functional monitor possesses the functions of being used either as a computer color CRT monitor or at the same time as a multi system color television. Apart from these, there are other additional functions of its such as that of Karaoke and AV output/input and FM radio receiver. It does not need for the external speaker and the input of AV signals to operate the computer in multi-media way. It is particularly convenient for the interactive mutual-act data network which is composed of computers, broadcast televisions and telecommunications.
