Each microcup contains four colored particles (yellow, white, red, blue) suspended in a transparent fluid, including positively charged red and blue particles, and negatively charged yellow and white particles. Each particle has a different degree of attraction to each corresponding electric field force. When each segment code block is independently controlled, the output duration of each voltage can be artificially controlled to control the movement of each particle to achieve particle color display (attracted to the upper layer). Therefore, when a positive or negative electric field is applied, the corresponding particles will move to the top, showing the required colors and patterns.

[0081] Preferably, since the electronic paper film has bistability, that is, when the electric field reaches equilibrium, the particles will still stay in place after power-off, so that the original image can still be displayed after power-off.
