[0002] Traditional blackboards can only write with chalk, cannot play videos on the blackboard, browse the web, cannot push teaching content to the cloud, and cannot touch and interact like LCD whiteboards; with the development of technology, computers are gradually being moved into classrooms, electrified Teaching has become a trend in teaching, such as projectors and electronic whiteboards
However, both projectors and electronic whiteboards completely digitize traditional blackboards or whiteboards, but according to people’s years of use habits and convenience, writing with chalk or pens is the most convenient, flexible, and time-saving. In one of my classes, chalk is still used a lot; and if there is a power outage, electronic equipment cannot be used

Abstract
The invention discloses an intelligent blackboard which comprises a writing plate, a transparent shoe plate, a touch control film and a display. The transparent shoe plate is arranged between the writing plate and the touch control film, and the display is arranged in the side, opposite to the transparent shoe plate, of the touch control film. The writing plate further comprises a transparent basematerial and a matte coat coating one surface of the transparent base material, the matte coat is obtained by a coating material under ultraviolet irradiation, and the coating material is composed, by weight, of fatty group polyurethane triarylate, 1,6-hexanediol diacrylate, ethylene glycol diglycidylether, alkyl modified organosiloxane, hydroxyl toluene butyl ester, organic thermosetting poly methylurea resin, 4-acryloyl morpholine, 2-hydroxy-2-methyl-1-phenyl-1-acetone, mesyloxy ketone, a coloring pigment and castor oil polyglycidyl ether. According to the intelligent blackboards, the crosslinking rate of components in the coating material is improved, the coating material can be thermoset needless of too much heat energy, the printing precision is high, and the yield rate is improved.
Description
Technical field[0001]The present invention relates to the technical field of touch control, in particular to a smart blackboard.Background technique[0002]The traditional blackboard can only write chalk, cannot play video on the blackboard, browse the web, cannot push the teaching content to the cloud, and cannot interact with touch like an LCD whiteboard; with the development of technology, computers are gradually moved to the classroom and become electrified Teaching has become a trend in teaching, such as projectors and electronic whiteboards. However, projectors and electronic whiteboards are all traditional blackboards or whiteboards completely electronic, but according to people's many years of use habits and convenience, writing with chalk or pen is the most convenient, flexible, and time-saving, and time is limited. In one of the classes, chalk is often used; and if there is a power outage, the electronic equipment cannot be used.Summary of the invention[0003]The present inve...
