is the world's first producer of high-brightness large-sized LCD blackboard. Users can write on the product without pen or electricity, thus thoroughly removing dust and protecting our eyes. The handwriting thereon is of high brightness, and can be erased globally or locally by one touch or transmitted or saved intelligently. The product is a perfect alternative to the traditional chalkboards and whiteboard. Wicue intelligent LCD writing board has its complete independent intellectual property with its independent patent. We have applied for more than 100 domestic and international patents for the product accumulatively, and have independently developed the automatic roll-to-roll production line of wide liquid crystal film featuring low cost and high yield.
