    • 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 (t switch ), 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.
    • 本发明提供了用于电致变色有源矩阵器件的快速灰度级操作的装置。 这通过改变电致变色矩阵器件中的多个矩阵元素的灰阶状态的方法来实现。 所述方法包括具有等于或小于矩阵元素(tswitch)的切换时间的持续时间的至少一个开关周期(LOAD),其中每个开关周期包括以下步骤:选择要改变的矩阵元素, 将所选择的矩阵元件连接到驱动电位,并且控制每个所述选定的矩阵元件的驱动电位,使得它们达到它们各自期望的灰度状态。 本发明还提供了满足该方法要求的电致变色矩阵装置。
