Portable wired/wireless high-performance display adaptor and adaptation method thereof

Abstract

The invention provides a portable wired / wireless high-performance display adaptor and an adaptation method thereof. The adaptor comprises a signal forwarding device and a signal receiving and processing device, and is characterized in that the signal forwarding device comprises a circuit module of a host side UWB transceiver, a signal type discrimination module, a USB signal detecting module and a USB signal converting module; and the signal receiving and processing device comprises a circuit module of a mobile side UWB transceiver, a host signal restore module, an image signal detecting module, a power supply module and an initialization module. The adaptor has a flexible transmission mode, can perform wired or wireless transmission, and also can be used as an external discrete graphics for a host. The adaptation method realizes the initialization of the adaptor through the initialization module when the host starts, and is characterized by comprising an adapting process when the inside of the computer host is not provided with a display adaptor. The adaptor has the flexible transmission mode, and is suitable for portable and high performance image adaptive display and high performance multi-screen mirror image or extension.

Description

technical field [0001] The invention relates to computer image display technology, in particular to a wired / wireless portable high-performance display adapter and a signal transmission method thereof. Background technique [0002] The image display card is an important part of the computer hardware system. It is mainly responsible for processing the image signal sent by the CPU, including data format conversion, special effect processing, etc., and transmitting the processed data to the display for display. Existing image display cards can be divided into two types, namely embedded image display cards and slot-type image display cards. The so-called embedded image display card means that the image display chip is directly integrated on the north bridge chip of the computer motherboard, so that the computer hardware structure is simpler and the data transmission rate is faster. However, this method is based on reducing the image processing performance. . For some applicatio...

AI Technical Summary

Problems solved by technology

These devices are generally used in the occasions of multi-screen expansion or mirroring display. The essence is only to convert the format of the existing image signal, so a high-performance slot-type image display card is needed to assist. If there is no image auxiliary display card, then the device will not work at all

Moreover, since the portable device does not have a high-performance image processing chip inside, and does not have any 3D image or special effect display acceleration function, it cannot be regarded as an image display card in the true sense, and can only be used in relatively simple image display occasions.

In addition, under the premise of not considering the compatibility between the compression application software and other application software, the process of compressing the image signal into a USB data packet increases the burden on the CPU of the host computer, especially when a higher quality image signal is to be transmitted. For example, 3D game screens, high-definition video streams, etc., will greatly increase the CPU usage, and even cause the entire system to crash, so at present, the application prospect of this product is not broad, and further improvement is needed

In addition, the utility model patent ZL200620016004.X proposes an image display adapter using a USB interface, however, no specific working method is mentioned in the utility model patent

According to the description of the patent, it can be known that the working principle of the device is similar to the product design idea of ​​Displaylink, and it also needs to rely on the existing image display card to make the computer operate normally, that is, if there is no other image display card support, the computer will not start normally

And, because this device needs to have the connection of USB line, so the length of connecting line has limited the distance between this device and display device and computer host
