More Book Details

Description of the Book:

A flat panel display has been fabricated using spherical magnetic particles sandwiched between two transparent glass plates. The particles are each half white and half black corresponding to opposite magnetic poles. A 10 by 15 electromagnetic element matrix has been fabricated to address the display. After uniform magnetization of the matrix elements, the polarity of elements is reversed with current supplied through microswitches closed by a punched card. The display plate placed over the matrix will display alpha-numerics in accordance with the program punched into the card. The alpha-numerics can be displayed either as white on a black background or a black on a white background. (Author
