What is an LCD Blackboard? LCD Blackboard is a kind of electronic device that uses high-tech flexible liquid crystal technology to display words, patterns and graphics by pressure. You can write or draw on the screen with any hard but not sharp object, even with your finger nail.
What is the core material of a blackboard?
The core material of the blackboard is cholesteric liquid crystal polymer filled in between two ITO films. When pressure is put on the surface of the writing film, the bistable liquid crystal molecules will change from normal state to another, which can reflex ambient light. Therefore, you can see the writing marks left on the writing film.
