Title: Display device
Inventor: NAKANISHI MASAHIRO
IPC: G09G3/38
Filed: 2000-06-20
Abstract: PROBLEM TO BE SOLVED: To prevent complication of wiring work and an increase in a cost. SOLUTION: When an AC voltage is applied to carrying electrode groups 3a, 3b, 3c, electrostatic force is generated to circularly move twisting balls 1 inside a carrying guide 2 to the A direction as illustrated. In that state, when applying a DC voltage having an arbitrary polarity to rotation electrodes 4a, 4b, the twisting ball 1 rotates to a direction according to the polarity. Because the surface of the twisting ball 1 is formed with a black area 1a and a white area 1b, a black display or white display is executed according to the rotated direction. The display device displays information by use of this principle. Because only wiring of the carrying electrode groups 3a, 3b, 3c and the rotation electrodes 4a, 4b is required, wiring work is simplified compared to a conventional display device to reduce a production cost and product cost.
