A facile method for designing and fabricating a concave mirror from a 3D printed mold is proposed for a seamless modular curved-edge display. The concave mirror is placed on the seam of modular curved-edge display, thereby reflecting images at the curved-edge area toward the observer direction. By investigating the concave mirror structures based on parametric modeling, we obtain a continuous image in a modular curved-edge display by optically concealing the seam. We also analyze the luminance distribution and the viewing angle of the seamless modular curved-edge display to show the capability of concealing the seam by the concave mirror.

基于3D打印的镜像图像组件，用于无缝模块化弯曲边缘显示器

提出了一种用于从3D打印模具设计和制造凹面镜的简便方法，以用于无缝模块化弯曲边缘显示器。将凹面镜放置在模块化弯曲边缘显示器的接缝上，从而将弯曲边缘区域的图像朝向观察者方向反射。通过研究基于参数化建模的凹面镜结构，我们通过光学隐藏接缝获得了模块化曲面边缘显示器中的连续图像。我们还分析了无缝模块化弯曲边缘显示器的亮度分布和视角，以显示通过凹面镜隐藏接缝的能力。
