Problems solved by technology

The above two tasks make the CPU resources excessively occupied, affect the processing speed of the CPU, and make it impossible to display high-quality images in real time
[0006] 2. High cost
Using the screen capture method, both the main device side and the display device side need a CPU with strong computing power to encode and decode, so the cost is relatively high

Embodiment Construction

[0041] Please see figure 1 , which illustrates the basic principles of the invention. This figure shows the signal transmission process that the master device realizes the display on the display device through the wireless network.

[0042] As shown in the figure, the display information and sound information of the computer or electronic device 101 are converted into wireless network messages, which are transmitted to the display device through the wireless network, and the received wireless network messages are decoded by the display device to finally form a pixel The information and display control signals drive the display to display corresponding information, and form audio digital signals to drive the speaker to sound.

[0043] As shown in the figure, the computer or electronic device 101 transmits the display information to be displayed to the image controller 102; the image controller 102 generates corresponding pixel information and display control signals (such as f...

Abstract

The wireless display device includes main device end (MDE) and display device end (DDE). MDE possesses display adapter in use for receiving display info, and converting it to pixel info and display control info. DDE possesses display controller in use for receiving pixel info and display control info, and drives luminescence part based on the said info. MDE possesses wireless transmission process(WTP) unit in use for receiving pixel info and display control info sent from display adapter, and encodes the message of the received info, and sends out the encoded message. DDE also possesses WTP unit in use for receiving message sent from WTP unit at MDE, and decodes it to pixel info and display control signal, which is output to display controller at display end. The invention also discloseswireless display method. Comparing with prior art, the invention possesses advantages of lightening workload of CPU, and reducing cost.

Description

technical field [0001] The present invention relates to wireless transmission technology, in particular to a wireless display device. The invention also provides a wireless display method. Background technique [0002] At present, computers or other electronic equipment (set-top box STB, video compression disc VCD playback equipment, digital video disk DVD playback equipment, personal television video recorder PVR) and display equipment (cathode ray tube CRT or liquid crystal display LCD, projector, TV, high-definition television ) are mainly connected by cables. To facilitate connectivity, wireless display technology is also developing rapidly. Especially in the context of the increasingly mature ultra-high bandwidth wireless network UWB technology, the prospect of wireless display technology is even broader. [0003] The current wireless display technology is mainly based on screen capture technology. Screen capture technology is to use specially designed software on t...
