As a new product, the small blackboard of light energy and the blackboard of light energy are produced under the background of the rapid development of science and technology and the increasing awareness of environmental protection, which has certain historical inevitability. As a great country with a brilliant cultural history of 5000 years, China has always been in a leading position in the invention, creation and use of writing tools and methods. Reviewing the innovation process of human writing tools, we can clearly feel the progress of human civilization.

It is not difficult to see from the historical literature that the earliest recording tool of mankind should be rope, that is, we often say knot rope recording. When the brain was patched up, the scene was probably like this:

However, this complicated and inefficient way of keeping records did not last long, and oracle was born. The appearance of Oracle Bones not only created the earliest Chinese characters, but also increased the level of writing materials by one level.

On the basis of oracle bone inscriptions, we have tried to write on the golden tripod, bamboo and silk.

The invention of writing materials with cross-epochal significance, the use of paper is the key to the inheritance and development of human civilization. As one of the four great inventions in China, paper has been used for nearly 2000 years, and is still an indispensable part of our daily life and office.

However, the improvement, invention and creation of writing materials have never stopped. The widespread use of paper has led to the over-cutting of raw materials and trees for making paper, which has led to serious soil erosion, intensified rocky desertification, greenhouse effect leading to climate warming and a series of environmental problems, resulting in frequent natural disasters, making mankind realize the urgency of the invention and use of new writing materials.

Based on the above reality, Howshow light blackboard and light energy blackboard came into being. Good writing light energy blackboard uses flexible liquid crystal technology, fundamentally solving the writing must rely on paper and ink pen thinking. By adding flexible liquid crystals to the PET material and relying on pure physical pressure sensing, the easy-to-write light energy blackboard can replace traditional paper and ink pens. This innovation of writing materials subverts the traditional writing materials, but retains people's traditional writing habits. The handwriting is almost the same as the traditional ink pen, and the degree of experience and precision are extremely high, thus realizing the perfect combination of tradition and modern, more easily accepted by people.

More importantly, the Howshow light blackboard can be reused more than 100,000 times, equivalent to saving more than 100,000 sheets of paper.

According to statistics:

If you waste less than 1500 pieces of paper, you can cut down a tree.

Wasting less than 100000 sheets of paper means saving 66 trees.

A tablet can save 66 trees!!! Isn't it tree planting day every day? Protecting the environment is so simple as long as you take a little action! One small step forward in thinking, and one big step in civilization. Protect the environment, start with you and me.

Finally, please attach a few beautiful maps to enjoy the black technology artifact.
