Problems solved by technology

[0002] In the process of computer professional education and teaching, it is often necessary to use computer teaching display screens. General teaching display screens are fixed on the podium, which is difficult to adjust. At the same time, in the long-term teaching practice process, when students watch the teaching display screen, due When sunlight shines on the teaching display screen, it is difficult for students to see the contents of the display screen clearly. Therefore, we propose a rotatable computer teaching display screen with shading function to solve the above problems
