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.

Abstract: Display device is based on layer break up or layer displacement having at least two different states, in which one of the fluids, e.g., oil in a first state, adjoins at least a first support plate and, in the second state, the other fluid at least partly adjoins the first support plate. In one embodiment, a picture element corresponds to a substantially closed space and, in the first state, the other fluid layer substantially completely adjoins both support plates and is divided in two sub-layers. This makes it possible, on the one hand, to use lower voltages to make displacement occur. On the other hand, this opens the opportunity to color displays.
