Abstract

The present invention provides means for rapid grayscale operation of electrochromic active-matrix devices. This is achieved through a method of changing grayscale-states for a plurality of matrix-elements in an electrochromic matrix device. Said method comprising at least one switch cycle (LOAD) with a duration that is equal to or less than the switch time of the matrix elements (tswitch), wherein each switch cycle comprises the steps of selecting matrix-elements that are to be changed, connecting said selected matrix-elements to a drive-potential, and controlling the drive-potential for each said selected matrix-elements, such that they reach their respective desired grayscale states. The present invention further provides electrochromic matrix devices that meet the requirements of the method.
