Four-in-one color liquid crystal TV set

Abstract

The invention relates to a four in one colorful liquid television that integrates colorful liquid computer display, television, DVD and HI-FI audio and has plural audio and video functions. It can play discs as DVD, VCD, CD and so on, and its functions is powerful and fully. The display has not X ray radiation. Because the structure makes full advantage of the shared circuit part, the repetition use of circuit is avoided. A keyboard and an infrared remote controller would control the function circuit part. The signal switching circuit is controlled by service function. And compounding of the current circuit would be done by the multi-branch power supply output controlling circuit. It is convenience to be used and simple to be operated. It can be widely used for home, hotel, office, school and enterprises or institutions.

Description

Technical field [0001] The invention belongs to the technical field of television sets, and more specifically relates to a device with multiple audio-visual functions integrating a color liquid crystal computer monitor, a television set, a DVD, and a high-fidelity sound system. Background technique [0002] Computers, TV sets, digital laser video disc (DVD) machines, and high-fidelity speakers are necessities in daily work and life. At present, most of the manufacturers of these devices make them into single units, and the TV set only has the basic function of watching TV. , it can watch programs broadcast by TV stations and listen to their sound, and can also be used as an image display for DVD players and video recorders. But it can not replace the DVD player, and directly play DVD, VCD, CD and other audio-visual product discs; the computer monitor only has a simple VGA interface display function, and cannot watch TV programs and cannot be used as an image display for DVD ...

AI Technical Summary

Problems solved by technology

This technical scheme puts the TV movement, the DVD machine movement and the audio power amplifier in a casing to solve the complicated problem of connecting lines, but the TV movement, the DVD player movement and the audio power amplifier are all connected separately. It has its own independent operation buttons and remote control, and it still needs to be operated separately when using it

In addition, traditional computers and televisions use cathode ray tube (CRT) displays with analog signals. CRT displays are bulky, consume large power, and have strong X-ray radiation; new computers and televisions use liquid crystal (LCD) displays with digital signals. , the LCD display has small thickness, low power consumption, no X-ray radiation and is lightweight; but the LCD display of the computer adopts the progressive scanning video analog input signal of VGA format and the LCD display of the TV adopts the interlaced scanning video digital input signal of 656 format; The video signal output format of the DVD machine core is different due to the choice of the internal decoding chip. It can be an interlaced video digital output in 656 format or a progressive video analog output in VGA format. Low universal VGA format progressive scan video analog signal output decoder chip; obviously can not use a certain kind of LCD display to simply adopt the above two technical solutions or their combination to realize people's above wishes

In addition, for the multiple audio-visual functions that people expect, only one audio-visual function is used at the same time, and the circuits that have nothing to do with the audio-visual function are always in working condition, wasting electric energy
