  • LIQUID CRYSTAL HANDWRITING BOARD AND PREPARATION METHOD
    Publication number: 20220317502
    Abstract: The disclosure provides a liquid crystal handwriting board and a preparation method. The liquid crystal handwriting board successively includes a first substrate, a first conductive layer, a liquid crystal polymer layer, a second conductive layer and a second substrate, wherein a light-resisting component that can resist a specific wavelength is arranged in the first substrate, and the first conductive layer, the second conductive layer and the second substrate are transparent. In the liquid crystal handwriting board of the disclosure, the first substrate and the second substrate are both made of transparent materials, and the light-resisting component is added in the first substrate.
