Abstract:
An electrowetting display device includes an electrowetting pixel cell and a driving circuit. The electrowetting pixel cell including a polar liquid and a non-polar liquid disposed between a common electrode and a pixel electrode, the pixel electrode configured to receive a fixed voltage and the common electrode configured to receive a variable voltage that varies according to an image signal. The driving circuit configured to control an operation of the electrowetting pixel cell by, providing an image signal to the electrowetting pixel cell at a display interval where the electrowetting pixel cell displays an image, and providing a reset voltage to the electrowetting pixel cell at a reset interval. An absolute value of a difference between the voltage applied to the pixel electrode and the reset voltage is greater than that of a difference between the voltage applied to the pixel electrode and the voltage applied to the common electrode.
