With the approach of the 20 10 Shanghai World Expo, the exhibition industry in China has been developing in full swing recently. At present, China holds more than 1200 exhibitions every year, which is 10 times of the total number of domestic exhibitions in the 20 years before the reform and opening up. At present, there is still a big gap between China's convention and exhibition industry and the same industry abroad. The development of convention and exhibition industry will inevitably absorb new technologies, and the maturity of multimedia technology makes it possible for new technologies to be integrated into exhibitions. The application of multimedia technology in the exhibition improves the benefit of the exhibition, and the ultimate goal is to achieve better publicity effect.

The demand for high technology in the exhibition industry is very strong, and multimedia technology will be more applied to all aspects of exhibitions, organically combined with traditional exhibitions, and give full play to their respective advantages. Multimedia technology is a new technology based on computer, which can simultaneously acquire, process, edit, store, transmit, manage and express two or more different types of information media. The application of multimedia technology in the exhibition includes audio and video equipment, multimedia explanation technology, auditory, tactile and visual multimedia technology and multimedia design. Finally, more research directions and future development trends of display multimedia are discussed.
