The present invention relates to a wireless display system, and in particular, a short-range wireless communication method is used to efficiently transmit and receive signals between the main body of a PC and a display device, and to optimally design a combination structure of a display monitor, a keyboard, and a mouse. The present invention relates to a wireless display system that maximizes the efficiency, economy, ease of use, and utilization of home computing.

Conventional technology includes a predetermined operating system (Microsoft's "Mira" model), a processor, a board, a memory, and a wireless LAN module on a touch screen input type monitor, and transmits and receives data by using a PC wireless communication with digital PC. This type of work is being implemented, and Hitachi and Sambo Computers have released this type of wireless monitor.

As a problem of the prior art, first, in terms of signal processing, by adopting a digital wireless LAN transmission method for wireless digital communication, distortion and delay of a video signal displayed on a monitor cannot be transmitted in real time due to the limitation of speed. This is happening seriously. This approach is also uneconomical in terms of cost (manufacture and sale), which requires the operating system and high-performance data processor, board and memory to be mounted separately on the monitor. In addition, by adopting a touch screen input method, a user who is familiar with a keyboard and a mouse in a conventional desktop computer has a problem in that it causes inconvenience in use.

On the other hand, in the mechanical configuration of the monitor, while the conventional structure adopts a touch screen type display, the structure is simple, but the existing keyboard and mouse cannot be adopted organically (to date, it is compatible with Microsoft's "Mira" operating system). Keyboard and mouse support technology has not been developed) It causes inconvenience to users who are familiar with existing methods. In addition, although there is a technology for mounting a keyboard outside the side of a conventional monitor, there is a problem that the organic design technology for the keyboard and mouse combination method is not provided in a wireless display system using a conventional monitor.

The present invention for solving all these problems, adopts a signal processing method that avoids the signal processing of the existing digital wireless communication method, and provides an optimal display wireless display system by organically combining a keyboard and a mouse on a conventional monitor By providing the video signal quality of at least NTSC / PAL level, the video signal can be displayed on the wireless monitor in real time without delay of the video signal, enabling efficient computing work at a short distance and reducing the number of components and at the same time. It is to provide an easy-to-use and efficient wireless display system while significantly improving the economics by using the cost-effective parts.
