In this paper, we propose a method of chromatic aberration elimination in holographic display based on a zoomable liquid lens. The liquid lens is filled with two immiscible liquids and developed by using the principle of electrowetting. The shape at the liquid-liquid interface changes with the voltage applied to the liquid lens, so the focal length can be adjusted by changing the voltage. By using the liquid lens in the holographic display system, the position of the reconstructed image can be controlled. When three color lasers illuminate the corresponding holograms and the focal length of the liquid lens changes accordingly, three color images can coincide in the same location clearly. The experimental results verify its feasibility.
