    • A driving system (15, 10, 16) for reset-driving a bi-stable display device (1) which comprises bi-stable material of which an optical state changes when a drive voltage (VD) is applied across it and which substantially keeps its optical state unaltered in the absence of the drive voltage (VD). The driving system (15, 10, 16) generates, during an image update period (IUP), a sequence of phases. The sequence at least comprises a reset phase (RE), an address phase (AD) and an offset phase (OP). During the reset phase (RE) a previous optical state of the bi-stable material is changed into at least one of two limit optical states (B; W). During the address phase (AD) the at least one of the two limit optical states (B; W) is changed into an intermediate optical state (Gl, G2) in-between the two limit optical states (B, W). The two limit optical states (B, W) and the intermediate optical state (G1, G2) are called main optical states. During the offset phase (OP), starting from the intermediate optical state (G1, G2), extra optical states (ILG11, ILG12, ILG21, ILG22) are created which differ from the main optical states.
    • 一种用于复位驱动双稳态显示装置(1)的驱动系统(15,10,16),该驱动系统包括双稳态材料,当在其上施加驱动电压(VD)时光学状态改变,并且基本保持 在没有驱动电压(VD)的情况下,其光学状态不变。 驱动系统(15,10,16)在图像更新周期(IUP)期间产生一系列相位。 该序列至少包括复位阶段(RE),地址相位(AD)和偏移相位(OP)。 在复位阶段(RE)期间,双稳态材料的先前光学状态被改变为两个极限光学状态(B; W)中的至少一个。 在寻址阶段(AD)期间,两个极限光学状态(B; W)中的至少一个被改变为在两个极限光学状态(B,W)之间的中间光学状态(G1,G2)。 两个极限光学状态(B,W)和中间光学状态(G1,G2)被称为主光学状态。 在偏移相位(OP)期间,从中间光学状态(G1,G2)开始,产生与主光学状态不同的额外光学状态(ILG11,ILG12,ILG21,ILG22)。
