A facial method was used to enhance the dynamic response of polyvinyl chloride (PVC) gel tunable lenticular microlens array (LMA). The response time could be reduced using a discontinuous hydrophobic layer-modified electrode substrate due to a decrease in friction between the substrate surface and PVC gel. The application of DC voltage (V = -45 V) to LMA induced a response time <240 ms. The proposed PVC gel LMA looks promising for use in image processing and two/three-dimensional switchable displays due to its fast-dynamic response, good stability, compact structure, and easy fabrication.
