    • A method for driving an active matrix display having a first insulative substrate (1), a second insulative substrate (5), and a layer (7) of a material provided with an electro-optical effect between the first and second insulative substrates, the first insulative substrate carrying pixel electrodes (2) arranged in a matrix and a plurality of first parallel electrodes (4) separated from the pixel electrodes by regions (β) of an active layer (3) formed of ferro-­electric material, and the second insulative substrate carrying a plurality of second parallel electrodes (6) arranged in a direction perpendicular to the first parallel electrodes, the method comprising the steps of applying a selective voltage sequentially to each of said second electrodes or said first electrodes during respective selective periods, applying a data voltage to each of said first electrodes or said second electrodes during respective non-selective periods, and characterised by controlling the data voltage, and thereby the voltage applied to each region of the active layer during the non-selective period, such that inversion of more than half of an spontaneous polarisation of the region generated in the selective period is avoided.
    • 一种用于驱动具有第一绝缘衬底(1),第二绝缘衬底(5)和在第一和第二绝缘衬底之间提供电光效应的材料层(7)的有源矩阵显示器的方法, 第一绝缘衬底,其承载以矩阵形式布置的像素电极(2)和由像素电极与由铁电材料形成的有源层(3)的区域(β)分离的多个第一平行电极(4),第二绝缘衬底 绝缘衬底,其承载沿垂直于所述第一平行电极的方向排列的多个第二平行电极(6),所述方法包括以下步骤:在各个选择期间向每个所述第二电极或所述第一电极施加选择电压,施加 在各个非选择期期间对每个所述第一电极或所述第二电极的数据电压,并且其特征在于控制所述数据电压, 从而避免了在非选择性周期期间施加到有源层的每个区域的电压,从而避免了在选择期间产生的区域的自发极化的一半以上的反转。
