Dust-free and Environmental Protection Teaching Solution - LONBEST E-writing Blackboard
"Chalk + blackboard", as the standard configuration of traditional teaching, is still used in front-line teaching. Among them, chalk has made indelible contributions to human education and social development since its invention, but it has also caused considerable harm in use.
Chalk will produce a lot of dust during use, which not only pollutes the teaching environment of the classroom, reduces the service life of electronic teaching equipment, but also endangers the physical and mental health of teachers and students. Today, with the vigorous development of education informatization, it is necessary to solve the problem of dust pollution in classrooms from the root, and improve teaching efficiency while ensuring clean air in classrooms.
The LONBEST E-writing teaching blackboard has many functions such as dust-free and pollution-free, energy-saving and environmental protection, green eye protection, synchronous interconnection, etc. It completely solves the problem of dust pollution in the classroom and becomes the creator of a century-old writing revolution!
Dust-free and environmentally friendly: The LONBEST E-writing blackboard adopts liquid crystal pressure-sensitive display technology. When writing, as long as a certain pressure is given to the blackboard, the handwriting can be displayed. Therefore, any object with moderate hardness can be written on it, such as your finger joints or Nails, etc., without the use of consumables. It is highly energy-saving, green and healthy, keeps the classroom away from chalk and dust, and completely changes the historical phenomenon of teachers and students eating chalk dust.
It is also very convenient for erasing. The LONBEST E-writing blackboard has the functions of one-key erasing and partial erasing. The combination of the two can achieve the best erasing effect.
One-key erasing can be realized by simply pressing the erase button under the blackboard, which is convenient and quick.
Partial erasing can be realized only by covering the area to be erased with the palm or blackboard eraser. It is simple and practical, and perfectly restores the erasing method of the traditional blackboard.
Writing dexterity, green eye protection: Traditional blackboards use chalk to write, and it takes a lot of force to make the chalk rub against the board surface to leave handwriting. Therefore, it is easy for the teacher to write on the blackboard for a long time and cause sore wrists and fatigue. The LONBEST E-writing blackboard is pressure-sensitive, and it can leave handwriting with a very gentle force when writing, which can effectively reduce writing fatigue, especially in courses such as Chinese and mathematics with more writing on the blackboard.
In addition, LONBEST E-writing blackboard uses a special flexible writing film, which changes the internal crystal structure through external pressure, so that visible light with a wavelength of 500-560 is reflected, showing emerald green bright handwriting. Writing and display do not require any backlight, pure external natural light reflection, no electromagnetic radiation, long-term viewing does not irritate the eyes, and achieves the purpose of protecting students' eyesight.
Synchronous transmission & storage:LONBEST E-writing blackboard seamlessly connects the LCD writing board with the multimedia touch all-in-one machine through infrared touch interconnection technology. The handwriting written by the teacher on the E-writing blackboard will be synchronously transmitted to the multimedia display screen to increase the display area of the blackboard writing and prevent the problem that the students in the back row cannot see the blackboard writing clearly due to occlusion. At the same time, the blackboard writing can also be saved on the all-in-one machine with one key, which is convenient for students and teachers to view and use in the future.
