Multimedia technology we have mentioned, is the use of computers to text, graphics, images, animation, audio and video and other digital media information network to promote multimedia devices, and integrate it in a certain interactive interface that enables computer It has demonstrated the ability to interact in different media forms. It greatly changed the traditional methods of access to information, in line with people in the information age reading. The use of multimedia teaching methods in language subjects Situation and Countermeasures of the rapid development of modern science and technology, multimedia the new technological means at an unexpected and speed to penetrate into the field of education. Multimedia projection display system: For every corner of the classroom can see a clear image, our high-performance projector. Key performance indicators of the projector brightness: light intensity output to the projector on the screen, depending on the brightness of the light source and the optical system and the transmittance or reflectance of the liquid crystal panel. It describes the unit of time in response to the strength of the visual light radiation generated. Brightness uniformity: the projector output on the screen brightness differences in positions, reflecting the light source and optics uniformity and stability in different parts. Black and white contrast: black and white image on the screen portions of the light intensity ratio. The higher the ratio, from black to white gradient level, the more multimedia devices, thus richer color performance, the sharper the image. Screen: The screen looks beautiful, Burkina fine, soft, drape good, long-term use does not appear yellow and deformed, high life. Screen surface treatment using glass beads multimedia training room equipment, increase training projection brightness multimedia device designed to improve the projection. Electric screen with low noise motor drive, the sound is minimal. Projector hanger: Professional design, strong, beautiful, good adjustability. Cable: from long distance signal transmission, signal interference and durability considerations, we choose a good shielding effect, the smaller the impedance of the cable as the primary transmission cable import.
