This paper presents a simulation model for a large field‐of‐view, wide eye‐box, and high‐resolution ultra‐thin near‐eye display based on a freeform optical lens array. It creatively incorporates a polarization‐based optical folding technique (pancake lens), reducing the thickness of the simulation model to less than 1.4 cm (excluding the display screen). Compared to traditional VR devices, this significantly reduces the volume and weight of the equipment. The parameters of the simulation model are as follows: eye‐box size of 10mm, resolution utilization rate of 50%; the introduction of freeform optics greatly improves the imaging quality of the displayed images. At the same time, the field of view reaches 116° (single eye, vertical direction).
