Title:
OPERATION OF ELECTRICALLY COLORING DISPLAY MATRIX
Document Type and Number:
Japanese Patent JPS58129475
Kind Code:
A
Abstract:
A novel method and system are disclosed for multiplex addressing of the electrochromic elements in a matrix array which substantially eliminates cross talk. The method comprises reverse addressing. i.e. supplying erase information to the off points of the matrix, while addressing the on points, i.e. providing write information to the points desired to be colored. The electrochromic elements are arranged in columns and rows to form the matrix and appropriately controlled drivers supply the desired write and erase voltages to the elements.
