Pixel structure and operating principles of EWDs. The optical stack consists of a top plate, a glass substrate, indium tin oxide (ITO) electrodes, a hydrophobic insulator layer, pixel wall, colored oil, and water. ( a ) With an applied voltage, oil is shrunk to a corner and the pixel is in a white on-state. ( b ) With no voltage applied, oil spreads uniformly and the pixel is in a colored off-state.

Figure Lengend Snippet: Pixel structure and operating principles of EWDs. The optical stack consists of a top plate, a glass substrate, indium tin oxide (ITO) electrodes, a hydrophobic insulator layer, pixel wall, colored oil, and water. ( a ) With an applied voltage, oil is shrunk to a corner and the pixel is in a white on-state. ( b ) With no voltage applied, oil spreads uniformly and the pixel is in a colored off-state.

Article Snippet: In this paper, a new pixel circuit structure with four sub-electrodes is proposed, and a three-dimensional dynamic simulation model of EWDs was established by COMSOL Multiphysics.

Techniques:

The switch-on response curve of EWDs with a multi-electrode pixel structure. Oil ruptured in the area of sub-electrode 1 and moved rapidly toward the pixel corner. With the voltage applied to two adjacent sub electrodes, oil was further accelerated to move to the specified pixel corner. The oil ruptured at 0.7 ms and the pixel reached a maximum aperture ratio of 57.9% at 9.5 ms. It took only 4.7 ms to reach an aperture ratio of 50%.
