Electronic handwriting screen

Abstract

The embodiments of present invention disclose an electronic handwriting screen and relate to the field of electrophoretic display techniques. In the embodiment of present invention, because insulation spacing elements are provided between the electrophonic display functional film and the bottom electrode, when an appropriate voltage is applied between the top electrode and the bottom electrode, the top electrode is pressed so as to make the electrophonic display functional film contact with the bottom electrode, which shortens the distance between the top electrode and the bottom electrode and further increases the electric field force acting on the charged colorant particles; as a result, electrophoresis effect occurs in the electrophoresis liquid so that patterns are displayed or erased at the pressing location, and handwriting function is thereby realized without a touch screen, reducing the manufacturing costs for an electronic handwriting screen.
