摘要: The technology of electrowetting display (EWD) is the most important method for the traditional displays that can work more efficiently. When the voltage drives, the aperture ratio of the ink will reach 75% and the transmittance can reach 60%. Furthermore, the EWD technology has the advantages such as high transmittance, high switching speed, color performance, low power consumption, and etc. They make the advances of technology development for the transparent displays. However, due to the diffraction phenomenon resulted from periodic pixel structures, when the users observe the background object through the transparent display, the transmitted image will be blurred. In this paper, we recognized the problems by the simulation and constructed the optical model first. In order to avoid the diffraction, we use micro lens array to prevent the rays interfere on the micro structure, so that it will not produce the destructive and constructive interference, so the diffraction effect can be reduced. The micro lens array avoid the light touches the outer frame of EWD pixels. The simulations are simulate at different distance, and the distance of diffraction width is condensed to 91% with respect to the origin. In the future, this concept can apply in other transmitted images of transparent displays.
