Intelligent blackboard

Abstract

The invention discloses an intelligent blackboard. The intelligent blackboard comprises a blackboard frame. A piece of left anti-dazzle black transparent glass, a piece of middle anti-dazzle black transparent glass and a piece of right anti-dazzle black transparent glass are arranged in the blackboard frame. The three pieces of anti-dazzle black transparent glass constitute a blackboard plane. A nano touch film is attached to the back of the middle anti-dazzle black transparent glass. A display screen is installed on the back of the nano touch film. The display screen is connected with a host of an intelligent operating system. The intelligent blackboard has the advantages that people can write on the blackboard with a piece of chalk and a whiteboard pen, touch interaction can be achieved, a traditional ordinary white board, a traditional ordinary blackboard and an electronic whiteboard can be replaced by the intelligent blackboard, the blackboard has multiple functions, and the application range is wider; a better showing effect can be achieved during interactive demonstration, understanding and memorizing can be facilitated, teaching content can be saved, and student can conveniently conduct after-class study; the unique technology for changing the surface roughness of the anti-dazzle black transparent glass is adopted, highlight is filtered, the harm to the retina is reduced, and the health of the eyesight of children is facilitated.

Description

technical field [0001] The invention relates to a teaching blackboard, in particular to a new type of intelligent blackboard which can not only be written with chalk, but also can be written with a whiteboard pen, and can also perform touch interaction. Background technique [0002] Traditional blackboards for modern teaching can only be written with chalk, and they cannot be written with water pens at the same time, nor can they play videos on the blackboard, browse the web, cannot push teaching content to the cloud, and at the same time cannot perform touch interaction like an LCD whiteboard; similarly, in the office The whiteboard used can only be written with a water pen. Today, with the increasing application of computers, computers have gradually been moved into classrooms, and audio-visual teaching has become a trend in teaching, such as projectors and electronic whiteboards. [0003] At present, LCD whiteboards are beginning to enter more classrooms in schools, and ...

Problems solved by technology

[0007] In addition, the problem of the projector in modern multimedia teaching is that the brightness of the bulb is low. Students watching it for a long time will affect their eyesight, and the bulb needs to be replaced when its service life is over, which increases the cost of teaching and office work.

At the same time, the brightness of display screens currently on the market is relatively high, which will cause certain damage to children's retinas, and even damage the eyes after close-range touch interaction
