Abstract:
1. A matrix electrode-controlling device for driving a droplet, the matrix electrode-controlling device comprising: a substrate; a dielectric layer positioned on said substrate; a plurality of control electrodes positioned inside said dielectric layer in a matrix manner, each control electrode having a first conductive region and a second conductive region, wherein each first conductive region of the control electrodes in a same row are electrically connected to form a plurality of controlling rows, and wherein each second conductive region of the control electrodes in a same column are electrically connected to form a plurality of controlling columns; and a ground electrode positioned at a predetermined position around the control electrodes without generating an electromagnetic shielding effect; wherein the droplet is driven to move on or above said dielectric layer by applying a predetermined voltage to one of the controlling rows or to one of the controlling columns; and wherein the first and second conductive regions of the control electrode are driven independently.
