Abstract： Screen projection is to display the screen of the sender(mobile phone, computer and other intelligent display devices) on other intelligent display devices, which is an important way to improve users′ visual experience and real-time information sharing. The traditional screen projection system often adaptively adjusts the size of the image according to the size of the display device, which is easy to cause the phenomenon of fuzzy display content and uneven color distribution of the picture. In addition, it is also accompanied by complex equipment and single function. This paper proposes an intelligent screen projection system with Wi-Fi as the connection technology. The system connects to personal computers or mobile phones through Wi-Fi, and performs super-resolution reconstruction of images, videos and other files before screen sharing. During screen sharing, users can simultaneously mark and draw on the display screen. The test results show that this design has the characteristics of high resolution, easy operation and high flexibility.
