Abstract

The invention discloses an interactive touch control blackboard. A transparent supporting plate is arranged between a writing layer and a touch control layer of the interactive touch control blackboard. The writing layer further comprises transparent substrate, a matte coating layer and a glue layer, and the glue layer is uniformly arranged on the surface of one side of the transparent substrate.The matte coating layer is arranged on the surface of the other side, opposite to the glue layer, and the transparent supporting plate and the transparent substrate are in contact connection with thesurface of the glue layer. An LED backlight source lamp is arranged in a liquid crystal display screen. The interactive touch control blackboard further comprises a light sensor, which is used for detecting the ambient brightness of the external environment and converting the intensity of the sensed ambient brightness into an ambient brightness sensing electric signal containing brightness information. According to the invention, the writing function, the multimedia display and the intelligent touch interaction function of a conventional blackboard are integrated; the backlight brightness of the liquid crystal screen can be automatically adjusted so as to protect eyes of the user.

Description

technical field [0001] The invention relates to an interactive touch blackboard, which belongs to the field of modern educational equipment and touch technology. Background technique [0002] With the development of information technology, many products in the educational equipment industry are innovating in the direction of informatization and intelligence, such as: intelligent sign-in system, high-speed recorder for document entry, table with display terminal, etc. The blackboard in the classroom is one of the most frequently used facilities in daily teaching work. Teachers of all subjects must write content and convey knowledge on the blackboard for students. In the information age, teachers have rich and colorful teaching content, so they also put forward higher requirements for the functions of the blackboard. The blackboard can not only use chalk to write on the blackboard, but also present multimedia content that students love to see. Simultaneously, but existing int...
