With the increase of national investment in education informatization, projectors are widely used in primary and secondary schools when they build computer classrooms and multimedia classrooms. As a modern educational equipment, it not only breaks through the traditional educational methods, but also enriches the educational methods. However, due to the peculiarity of the education industry, it presents different characteristics from other industries when purchasing products. At present, there is a new standard for the purchase of projectors in the education industry. This is "two highs and one low". Two highs refers to higher resolution and brightness, and one low refers to lower maintenance costs. The two heights are mainly able to provide higher projection quality when there are more students in the classroom environment. The lower one is mainly due to the high frequency of use of educational projectors, the product consumption is faster than other projectors, and it is necessary to ensure the low maintenance cost in the later period. Therefore, in education procurement nowadays, users should not only value the price, but also need to adapt to local conditions and purchase on demand. This not only allows the procurement funds to be fully utilized, but also doubles the quality of education and the school ’s level of education. The original intention of education projection. In this issue, the editor recommends a few cost-effective educational projector products for the current procurement standards.
