Abstract

A screen detachable and updateable A/V radio frequency device includes a motherboard and a keyboard, at least one wireless A/V transmitter, a wired A/V signal and power wire, an assembling-joint A/V signal and power wire and at least one random display device. The motherboard and the keyboard are installed on a notebook computer, i.e., a palm computer or a pocket type compute. The wireless A/V transmitter is installed within the mainframe. One end of the wired A/V signal and power wire is connected to the audio/video signal and power wire and another end thereof is connected to the wireless A/V transmitter. One end of the assembling-joint A/V signal and power wire is connected to the audio/video signal and power wire and another end thereof is connected to an assembling joint.

Claims

1. A screen detachable and updateable A/V radio frequency device comprising:

at least one mother board and one keyboard;

at least one wireless A/V transmitter installed in the interior of the mainframe for providing functions of digital A/V signals processing, modulation and transmitting;

a wired A/V signal and power wire having one end connected to an audio/video signal and power wire near the mainframe, and another end thereof being connected to said wireless A/V transmitter, by the audio/video signal and power wire near the mainframe to provide power to said wireless A/V transmitter and transfer A/V signals;

an assembling-joint A/V signal and power wire having one end connected the audio/video signal and power wire near the mainframe, and another end thereof being connected to an assembling joint; and

at least one random display device connected to the assembling joint of said assembling-joint A/V signal and power wire;

wherein said random display device directly receives the signals from said audio/video signal and power wire near the mainframe, and provides wireless A/V signals from a wireless transmission mainframe to other external wireless receiving and display device through said wireless A/V transmitter.

2. The screen detachable and updateable A/V radio frequency device as claim in claim 1, wherein the external wireless receiving and display device is a TV type display.

3. The screen detachable and updateable A/V radio frequency device as claim in claim 1, wherein the external wireless receiving and display device is a flat type display.

4. The screen detachable and updateable A/V radio frequency device as claim in claim 1, wherein the external wireless receiving and display device is a plasma display.

5. The screen detachable and updateable A/V radio frequency device as claim in claim 1, wherein the external wireless receiving and display device is a general random liquid crystal display.
