Abstract
An electrophoretic display capable of reducing passive matrix coupling effect includes an electrophoretic panel, a plurality of first scan lines, and a plurality of second scan lines. The electrophoretic panel includes a plurality of pixels. Each pixel of the plurality of pixels corresponds to a storage capacitor, and the storage capacitor is coupled to a first scan line and a second scan line. When the pixel is used for displaying a first color, the first scan line receives a first driving voltage, the second scan line is coupled to ground, and other first scan lines and other second scan lines receive a first voltage. A voltage difference between the first driving voltage and the first voltage and a voltage difference between the ground and the first voltage are smaller than a first threshold value corresponding to the first color.
