A functional multimedia teaching using led display

Abstract

The invention belongs to the technical field of teaching equipment, in particular to a functional LED display screen for multimedia teaching, comprising a support table, the left and right ends of the upper surface of the support table are fixedly connected with vertical baffles, and two vertical baffles A transverse baffle is fixedly connected therebetween, an arc-shaped sleeve is fixedly connected inside the support table, a second limit block is fixedly connected to the lower end of the angle adjustment crank, and the second limit block is slidably connected to the arc-shaped sleeve On the inner surface of the cylinder, a cylinder is fixedly connected to the middle of the rear side of the upper surface of the support table, a pneumatic sleeve is fixedly connected above the cylinder, and the upper left of the pneumatic sleeve is sleeved and slidably connected to the lower end of the pneumatic lifting rod. The upper end of the rod is fixedly connected with the LED display body, and the middle part of the rear side is at the top. This functional multimedia teaching uses the LED display screen to shield the strong light from the outside world, and will not cause the sight of the LED display screen to be reflected from a distance. The characteristics of improving the teaching effect of LED display.

Problems solved by technology

[0003] In teaching, LED display screens are often used to improve the practicality and interest of teaching, and can present internal uses that cannot be presented on blackboards in teaching. During the use of LED display screens, due to the influence of external environmental factors, When the external light is too strong, it will cause the sight of the LED display screen to be reflected when standing in the distance, which will affect the teaching effect of the LED display screen.
