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

The driven blackboard of charged sub-display screen
Technical field
The present invention relates to teaching equipment.
Background technology
Classroom has generally adopted audiovisual teaching equipment at present, as driven blackboard and projecting apparatus.Projecting apparatus is to hang curtain again in the front of blackboard, hangs the projecting apparatus main frame on the ceiling of classroom, and main frame is connected with the computer at dais again.Its deficiency is, during the projecting apparatus teaching, curtain blocks blackboard, and blackboard is write simultaneously, and need block window and make the indoor light dimness image of just breaking forth, and influences student's light.
Along with the progress of electronic technology, large-area ultrathin formula electronic display is come out, and also is not used in the classroom up till now.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of existing classroom audiovisual teaching equipment, propose a kind of driven blackboard of charged sub-display screen.
Technical scheme of the present invention is, it comprises driven blackboard and electronic display, it is characterized in that, on the top side of driven blackboard and bottom side body of wall slide rail is installed, and travelling carriage is installed on slide rail, and electronic display is fixed on the travelling carriage.
Good effect of the present invention is: 1, electronic display move left and right on slide rail when writing with driven blackboard, can move to driven blackboard one side easily; 2, no longer adopt the projection pattern electronic teaching, avoided blocking of curtain, and no longer block window light, make the classroom bright.
