Calibration Method for the Panel-type Multi-view Display

Abstract

We propose a novel calibration method which can be applied to all kinds of panel-type multi-view displays. We analyze how the angular, the axial, and the lateral misalignment affects the 3D image quality in a panel-type multi-view display. We demonstrate the ray optics simulation with a 3-view slanted parallax barrier system using pentile display for the quantitative calculation. Based on the analysis, we propose a new alignment pattern for all kinds of panel-type multi-view displays. The proposed pattern is sensitive to all of the angular, the axial, and the lateral misalignments. The high spatial frequency images and on and off alignment in the proposed pattern help observers to calibrate the system easily. We theoretically show the generality of the proposed alignment pattern and verify the pattern with image simulations and experiments.

Correction of distorted 3-D images for misalignment of an optical structure in a multiview 3-D display system

“…15 The angular misalignment implies the mismatch between the designed and assembled angles of a slanted optical plate. The axial misalignment can occur when the assembled gap between the optical plate and 2-D display panel is different from the designed gap.…”
