Educational projectors are mainly aimed at classroom teaching by school teachers; traditional projectors are not easy to carry. Due to the naughty students in school classrooms, projectors are not safe to place in classrooms and are easily damaged by students.

Its general weight will not exceed 0.2Kg, and some do not even need fan cooling or ultra-small silent fan cooling.
Educational projectors need to have:
1. Clear handwriting Educational projectors most often display text and images, at least a resolution of 1024*768 or more, and a contrast ratio of more than 3000 lumens, so that students in the back row can see the projection clearly
2. Short-focus large screen;
3. Accurate color;
4. Easy operation;
5. Features such as multiple connection methods.
