Light field displays offer promising advances for augmented reality (AR) and virtual reality (VR) applications by providing depth information and enabling realistic visual experiences. However, traditional designs often suffer from mechanical errors and optical distortions that affect image quality. Blurred images cause users visual fatigue and discomfort, affecting visual health. This paper presents a region-based imaging correction method suitable for lens array near-field display. By dividing the display into regions and applying imaging correction locally based on the central reference point, the proposed method can effectively reduce the effect of aberration and mechanical error on the whole field of view. We demonstrated significant improvements in image sharpness and visual fidelity through algorithmic validation. The results highlight the potential of region-based correction techniques to improve optical field display performance.
