| 20080204370 | Display Device - A display device or optical switch, based on layer break up or layer displacement having at least two different states, in which one of the fluids ( | 08-28-2008 |
| 20090141335 | Display device - 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. | 06-04-2009 |

| 20100128015 | ELECTROWETTING ELEMENT, DISPLAY DEVICE AND CONTROL SYSTEM - The present invention relates to an electrowetting element for a display device, a display device and a control system for controlling at least one electrowetting element. The electrowetting element comprises: a radiation valve comprising a first fluid and a second fluid immiscible with the first fluid, wherein the first and second fluids are configurable to change a characteristic of radiation passing through at least one of the first and second fluids; and an electrically switchable part switchable between a reflective mode for reflecting radiation incident on the switchable part and towards the radiation valve, and a transmissive mode for transmitting radiation incident on the switchable part through the switchable part and towards the radiation valve. | 05-27-2010 |
| 20100177026 | ELECTROWETTING SYSTEM AND METHOD FOR OPERATING - The present invention relates to an electrowetting system comprising an electrowetting element, a driver stage for applying a voltage to the element, and a switch connecting the electrowetting element to an output of the driver stage. The element comprises a first fluid and a second, immiscible fluid. The instantaneous position of the fluids is dependent on the voltage applied to the element, the voltage being set when the switch is closed. The voltage on the element is substantially maintained during a holding state longer than 70 ms when the switch is open. | 07-15-2010 |
| 20100296149 | OPTICAL APPARATUS - Optical apparatus for a display device. The optical apparatus comprises a cavity, and a first fluid ( | 11-25-2010 |
| 20110116153 | DISPLAY DEVICE - 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. | 05-19-2011 |

| 20100321760 | DISPLAY DEVICE - A display device comprising picture elements, which are constituted by electrowetting elements having at least one first fluid and a second fluid immiscible with each other within a space between a first support plate and a second support plate, the second fluid being electro-conductive or polar. The first fluid in each element is at the side of the first support plate confined by element walls, and the second fluid is shared by a plurality of picture elements, characterised by a preventer for preventing first fluid portions from being expelled from its confinement when forces other than electrowetting forces are exerted on this fluid. | 12-23-2010 |
