Abstract
The present invention relates to an active matrix display device, more particularly an electrowetting display device, comprising at least two rows of pixels and being provided with selection wires (RW) and data wires (COL) for addressing of the pixels. The pixels in each row are arranged with a respective connection (CW) to a common reset (RST) wire that is arranged to transmit a reset signal. The respective connection (CW) is arranged to be interconnected with the data wire (COL) of the pixel when the pixel is addressed. Further, the respective connection (CW) is arranged with a signal blocking element (D) for preventing a data signal of the pixel from propagating via the reset wire (RST) to pixels in the same row.
