Disclosed are a holographic reconstructing device and its application for portable electronic products. The holographic reconstructing device includes a compound hologram (9), a hologram seat (91), and a rebuilding light source (12). The compound hologram (9) is a flat-disk contour and disposed on the hologram seat (91). The rebuilding light source (12) is an LED and disposed under the hologram seat (91). The LED takes advantage of a small magnitude, less electricity consumption, simplified components, and a narrow bandwidth to definite a rebuilt image. The application of the flat-disk compound hologram is in a smooth-lying placement while reconstructing, which preferably occupies less space and facilitates user's observation as the rebuilt image is placed on the top of the compound hologram. The embedding of the holographic reconstructing device into the products would not affect the dimension of the products, thereby exhibiting realistic images on an individual space and forming a strong visual, clear impression, and a newly entertaining effect.
