| 发明名称 | Electrowetting system and method for operating | ||
| 摘要 | 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. | ||

| 主权项 | 1. An electrowetting system comprising an electrowetting element, a driver stage for applying a voltage to the electrowetting element, and a switch connecting the electrowetting element to an output of the driver stage, the electrowetting element comprising a first fluid and a second, immiscible fluid, an instantaneous position of the first and second fluids being dependent on the voltage applied to the electrowetting element, the voltage being set when the switch is closed, and the voltage on the electrowetting element being substantially maintained during a holding time longer than 70 ms when the switch is open, the holding time ending before or when a display state of the electrowetting element has reduced to 90% of a display state on opening the switch. | ||
