The main structure of the liquid crystal handwriting Board includes a liquid crystal screen (film) 131 and a PCBA (short for Printed Circuit Board Assembly), that is, a PCB blank Board is formed into a control Circuit Board after being subjected to SMT loading or being subjected to DIP-in-package (short for PCBA). The liquid crystal screen 131 is composed of a fog film, an ITO film, a liquid crystal film, an ITO film and a black film from top to bottom, and the thickness, color, brightness, contrast, writing resistance and aging resistance of the product are determined by the selection of film materials and the formula of the liquid crystal. The liquid crystal in the liquid crystal panel 131 is generally a bistable cholesteric liquid crystal that is flat and arranged in layers with the molecules in the layers parallel to each other. FC state: the molecular long axis is perpendicular to the layer plane, with slight variations in the molecular long axis direction for different layers. P state: the long molecular axes are parallel to the layer plane, and the long molecular axes of different layers are slightly changed and arranged into a spiral structure along the normal direction of the layers.
