    • A driving circuit for driving an in-plane moving particle device has a pixel (P) comprising movable charged particles (PA). The pixel (P) has a reservoir electrode (RE), a display electrode (DE), and a gate electrode (GE) laterally placed in-between the reservoir electrode (RE) and the display electrode (DE). The driving circuit (DC) comprises a driver (DR), a controller (CO) which receives an input signal (OS) representing an image to be displayed on the moving particle device. The controller (CO) controls the driver (DR) to supply a first voltage difference (VDl) between the reservoir electrode (RE) and the gate electrode (GE) and a second voltage difference (VD2) between the gate electrode (GE) and the display electrode (DE). The image is written to the pixel (P) during a write phase (TW) by moving particles (PA) from the reservoir electrode (RE) via the gate electrode (GE) to the display electrode (DE) if the optical state of the pixel (P) should change in conformity with the image. If during the write phase (TW) the optical state of the pixel (P) should not change, the first voltage difference (VDl) has a first write level and the second voltage difference (VD2) has a second write level, both write levels are selected to repulse the particles (PA) from the gate electrode (GE). During a repulsion period (TR), the first voltage difference (VDl) has a level more repulsive to the particles than the first write level, and/or the second voltage difference (VD2) has a level more repulsive than the second write level.
    • 用于驱动面内移动粒子装置的驱动电路具有包括可移动带电粒子(PA)的像素(P)。 像素(P)具有横向放置在储存器电极(RE)和显示电极(DE)之间的储存器电极(RE),显示电极(DE)和栅电极(GE)。 驱动电路(DC)包括驱动器(DR),控制器(CO),其接收表示要在移动粒子装置上显示的图像的输入信号(OS)。 控制器(CO)控制驱动器(DR)以在储存电极(RE)和栅电极(GE)之间提供第一电压差(VD1),并且在栅电极(GE)和 显示电极(DE)。 在写入阶段(TW)期间,通过将粒子(PA)从储存电极(RE)经由栅电极(GE)移动到显示电极(DE),将图像写入像素(P),如果光学状态 像素(P)应该与图像一致。 如果在写入阶段(TW)期间,像素(P)的光学状态不应该改变,则第一电压差(VD1)具有第一写入电平,并且第二电压差(VD2)具有第二写入电平,两个写入电平 被选择为从栅电极(GE)中击退颗粒(PA)。 在排斥周期(TR)期间,第一电压差(VD1)具有比第一写入电平更为排斥粒子的电平,和/或第二电压差(VD2)具有比第二写入电平更具有排斥性的电平。
