Description
technical field [0001] The invention relates to the technical field of audio-visual equipment, in particular to an intelligent projection system for audio-visual education. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal. Projectors are widely used in homes, offices, schools, and entertainment venues. According to different working methods, there are different types such as CRT, LCD, and DLP. Projectors, under the background of the country's policy of stimulating domestic demand and the continuous improvement of people's income, the implementation of the rural cultural sharing project has further promoted the rapid growth of China's projector market. According to statistics, in 2010 China's projector market shipments reached 1.28 million units, an increas...
