Electric blackboard with electronic display screen

Abstract

The invention discloses an electric blackboard with an electronic display screen. Slide rails are arranged on the wall bodies at the top side and the bottom side of the electric blackboard, each slide rail is provided with a sliding frame, and the electronic display screen is fixed on the sliding frame. Because the electronic display screen moves left and right on the slide rails, when the electric blackboard is used, the electronic display screen can move to one side conveniently; and the electrification teaching of a projection mode is not adopted any longer, so as to avoid the shielding of a curtain, shielding of a window no longer, and make a classroom bright.

Description

technical field [0001] The present invention relates to teaching equipment. Background technique [0002] At present, school classrooms generally use audio-visual teaching equipment, such as electric blackboards and projectors. For the projector, a curtain is hung in front of the blackboard, and the host of the projector is hung on the ceiling of the classroom, and the host is connected to the computer on the podium. Its disadvantage is that when the projector is used for teaching, the curtain covers the blackboard, and writing on the blackboard cannot be done at the same time, and the windows need to be blocked to dim the indoor light to illuminate the image, which affects the students' light. [0003] With the advancement of electronic technology, large-area ultra-thin electronic display screens have come out, but they have not been used in classrooms so far. Contents of the invention [0004] The purpose of the present invention is to overcome the above-mentioned shor...

AI Technical Summary

Problems solved by technology

Its disadvantage is that when the projector is used for teaching, the curtain covers the blackboard, so it is impossible to write on the blackboard at the same time, and it is necessary to block the windows to dim the indoor light to illuminate the image, which affects the students' light.

[0003] With the advancement of electronic technology, large-area ultra-thin electronic display screens have come out, and there is no such thing as classrooms yet.
