Rotation mechanism for bichromal balls of a twisting ball display sheet based on contact potential charging |
摘要 |
A twisting ball display sheet is disclosed which utilizes a mechanism other than Zeta potential to create dipole moment to rotate a plurality of bichromal balls. The twisting ball display sheet comprises a transparent sheet which contains a plurality of bichromal balls. Each bichromal ball comprises two hemisphere. Each hemisphere has a material which has a different work function than the work function of the other hemisphere. The two different work functions of each bichromal ball create a dipole moment which at the presence of a proper electric filed will cause the bichromal ball to rotate.
