Anti-dazzle eye protective blackboard

Abstract

The invention discloses an anti-dazzle eye protective blackboard. The blackboard comprises a touch control panel and two writing boards, the touch control panel is installed on a first frame, the writing boards are installed on a second frame, the two ends of the first frame are in installation connection with the second frame via sheet metal, and the touch control panel and the writing boards arearranged in the same plane; the touch control panel further comprises a transparent body layer, an intermediate film layer, a touch control film and a liquid crystal display screen; the liquid crystal display screen includes an LED backlight source lamp; and the blackboard further comprises a light sensor used to detect the brightness of the ambient light and converts the weakness of the sensed brightness of the ambient light into an ambient brightness induction electric signal including magnitude information of the ambient light. According to the anti-dazzle eye protective blackboard, the intelligent panel capable of touch control interaction is combined with the writing boards, so that the blackboard has functions including play display, touch control interaction and writing, and the backlight brightness of the liquid crystal screen is adjusted automatically to protect the eyes of a user.

Description

technical field [0001] The invention relates to an eye-protecting blackboard, which belongs to the field of modern educational equipment and touch technology. Background technique [0002] In recent years, with the continuous deepening of education reform and the rapid development of information technology, smart classrooms have begun to emerge in China. The state advocates the use of information technology to present course content that was difficult to present in previous teaching, using scientific equipment and various educational technology platforms as much as possible, and strengthening the combination of teaching and information technology.

The introduction of multi-functional blackboards in classroom teaching is a new mode of writing teaching in classroom teaching. For the traditional projectors that are ...

AI Technical Summary

Problems solved by technology

Due to the infrared frame of the LCD whiteboard, it is impossible to achieve frameless infrared touch. When touching at close range, the brightness of the liquid crystal will irritate the eyes.

The traditional blackboard can only be used for writing with chalk, and cannot be interactively touched. To play materials, a projector and a curtain are needed, and the teaching process is cumbersome.

At the same time, when the existing smart blackboard is displayed on its liquid crystal display, its brightness is constant, but the brightness of the environment often changes in the morning, afternoon, evening and in different seasons. Due to the large difference between the brightness of the display and the brightness of the environment, it will affect The feelings and effects of students or audience watching
