Abstract: An electrochromic matrix display of the kind in which the display electrodes are supported on a substrate above a corresponding matrix of transistor switches employs constant current writing and potentiostatic erasure. The transistors are switchable by signals applied on respective gate lines to pass electric current on the respective drive lines to their display electrodes. Gate and drive selection means define the active gate and drive lines. During erasure, the potentiostatic erase voltage is applied to both ends of the selected drive lines simultaneously to speed up the current limited asynchronous erase operation. Optionally, the display may be driven alternately from opposite ends of the drive lines during a line-by-line writing operation.

Abstract: Each display electrode (1,2) is connected to a respective switch through a conductive path (3,4,5). The display electrodes are divided into a number of subsets each of which is formed in respective layers so that the electrodes of an upper subset overlap the edges (10) of the electrodes of the lower subset. The layers are separated by intermediate layers of electrically insulating material (11). The conductive paths from each higher subset pass through gaps between electrodes of any lower subset and through the insulating layers to connect their respective electrodes to the corresp. switches.
