摘要： An electrowetting panel includes a base substrate; an electrode array layer, including a plurality of electrodes arranged into an array; an insulating hydrophobic layer; a microfluidic channel layer located on the base substrate. Each electrode of the plurality of electrodes is connected to a driving circuit, and a droplet can move along a first direction by applying an electric voltage on each electrode. The insulating hydrophobic layer is located on the electrode array layer, and the microfluidic channel layer is located on the insulating hydrophobic layer. The electrodes includes a plurality of driving electrodes and a plurality of detecting electrodes. Along the first direction, a number N of the driving electrodes is located between every two adjacent detecting electrodes, where N is a natural number. The electrowetting panel also includes a detecting chip electrically connected to the detecting electrodes.
