“像移法”是一种基于光致发光-液晶显示器(PL-LCD)体系结构的新型显示器图像拼接设计,它增强了用无缝拼接的办法制作大屏幕显示器的基本概念。这项专利技术利用了光学透明棱镜的折射现象[1]。如果把两个完全相同的直角棱镜的斜面相对,那么,来自第一棱镜的入射光线将偏移一定距离从另一面出射时,但仍与入射光线保持平行。通过对棱镜的精确取向和适当选择,可以通过组合这些棱镜结构使光线向中间移动,从而达到无缝拼接的目的(图1)[2]。
Image Shift is a new display image mosaic design based on a PL-LCD architecture that enhances the basic concept of making large-screen displays seamlessly. This patented technology utilizes the refraction of optically clear prisms [1]. If two beveled faces of identical right-angle prisms are opposite, then the incident light from the first prism will deviate a certain distance from the other face, but still be parallel to the incident light. Through the precise orientation and proper selection of the prisms, the light can be moved to the middle by combining the prism structures so as to achieve the purpose of seamless splicing (FIG. 1) [2].
