Title:
電子紙ディスプレイ用の多色球体形成方法
Document Type and Number:
Japanese Patent JP4384746
Kind Code:
B2
Abstract:
Twisting balls (10) for an electric-paper display are formed from a polarizable material and encapsulated in a protective shell (12). The balls (10) are disposed between first and second electrodes (14, 16) which generate an electric field. The electric field polarizes each ball (10) transforming each into a dipole electret having a first and second charged poles. At least one colorant (20) is applied to each of the balls (10) to obtain multichromal balls such that the charged poles are distinct from each other. The polarized multichromal balls may then be used in fabricating an electric-paper display by encapsulating the balls (10) in an array such that each ball is capable of rotating in response to a selectively applied electric field.
