Diffractive Alignment of Dual Display Panels

초록

Recent flat -panel displays have become increasingly complicated to facilitate multiple display functions. In particular, the form of multilayered architectures for next -generation displays makes precise three-dimensional alignment of multiple panels a challenge. In this paper, a diffractive optical alignment marker is proposed to address the problem of three-dimensional alignment of distant dual panels beyond the depth -of -focus of a vision camera. The diffractive marker is effective to analyze the positional correlation of distant dual panels. The possibility of diffractive alignment in multilayer display fabrication is testified with numerical simulation and a proof -of -concept experiment.
