Integral imaging 3D display has a small field of view range, and the stray light between the microlens will cause degradation of reconstructed images. In view of these problems, this paper presents a pinhole/ microlens array structure with curved surface, which fits flexible display and curved surface display well. The parametric analysis of curved surface pinholes / microlens array according to the integrated imaging principle conducted, and the recording and reconstruction process of integrated imaging 3D display based on curved surface pinholes / microlens array was simulateed with TracePro. The results show that, in the recording and reconstruction process, the quality of reconstructed image can be improved by the curved surface pinholes / microlens array structure. Concretely, a larger visual angle of three-dimensional objects is obtained in recording process and the field angle of reconstructed image is larger relatively. The quality of reconstructed images are accessed by rotating the receiving screen, and it is found that the best images can be obtained when the curved degree of the curved surface pinholes / microlens array is 30°.
