摘要： An electrowetting system including a display device (1) having a plurality of electrowetting elements (2), including a first electrowetting element and a second electrowetting element, each being configurable in a plurality of different display states; and a display controller (104, 204) for electrical addressing of the plurality of electrowetting elements in order to switch the plurality of electrowetting elements between different display states. The display controller is arranged to address the first electrowetting element twice subsequently, separated by a first addressing interval, and to address the second electrowetting element twice subsequently, separated by a second addressing interval, the second addressing interval being longer than the first addressing interval. The present invention further relates to a display controller, a driver stage and a method of controlling a display device.

摘要： A display device based on e.g. oil layer break up or oil layer displacement having at least two different states, having a wall (13) height which is insignificant compared to the pixel width and also to the typical curvature of the oil interface at the tip of the dosing needle (15), the pixels are dosed without inserting the needle into the pixels. As the dosing needle no longer has to enter the pixel, pixels can be dosed with oil (5) from a relatively large injection needle.

摘要： An electrowetting display device comprises a picture element having a first support plate and a second support plate having a space therebetween having a first fluid and a second fluid immiscible with the first fluid. The first support plate comprises a display area, adjoining the space, within which the first fluid is confined and having a first surface adjoining the space. A wall protrudes from the first support plate and is formed outside the display area along a part of the perimeter of the display area. The wall has a second surface facing the display area and adjoining the space. An electrode has a first portion adjacent to the first surface and a second portion adjacent to at least a part of the second surface such that a surface of the second portion including a long side of a cross section of the second portion faces the display area.

摘要： A method of operating an electro-optic display apparatus, wherein the display apparatus includes a display device having image regions and a display driving system having a data input for selecting image regions. The data input is connected to the input of a distributor for providing signals for driving the image regions. Each image region has an active display state in which the image region is driven with an active voltage signal. The active voltage signal includes a first signal level which sets an image region to the active display state and a second signal level different from said first signal level and which is applied for a shorter duration than said first signal level. The method comprises the following three steps: (1) applying the first signal level to one of said image regions in response to receiving data on said data input indicating that said image region is to be set to the active display state, (2) applying the second signal level to said image region after said first signal level has been applied; and (3) reapplying said first signal level before receipt of further data for said image region on said data input.
