摘要

在裸眼LED 3D显示中，游标条纹对于传统视差屏障是明显的。本文提出了一种具有不同宽度的半透明狭缝(LTSs)的错位视差屏障来减弱游标条纹。由于LED显示屏存在野黑矩阵(BM)，会产生明显的游标条纹，我们扩大了LTS的宽度，并在其周期内适当移动狭缝。这种结构增加了LED显示屏视差屏障与像素之间的周期差，可以增加游标条纹重氮的亮度，使其显得更加稀疏。这样，在不增加立体像明显串扰的情况下，这两个周期产生的游标条纹被减弱。仿真和实验显示样机的性能表明，在裸眼LED三维显示中，游标条纹的重氮酮褪色且明显稀疏。其结果是，游标边缘这一显示显着减少，不可见的观看。

Parallax Barrier for Weakening Vernier Fringe in Naked-Eye LED 3D Display

In naked-eye LED 3D display, vernier fringe is apparent for a conventional parallax barrier. This paper presents an intended misplaced parallax barrier with discrepant width of Light Translucent Slits (LTSs) to weaken vernier fringe. Because of the wild Black Matrix (BM) of LED display, which causes apparent vernier fringe, we enlarge the width of the LTS and move the slits properly in their periods. This structure increases the periodic difference between the parallax barrier and pixel of the LED display, which can increase the brightness of the diazone of vernier fringe and make it to appear more sparsely. In this way, vernier fringe produced by those two periods is weakened at the condition that no obvious crosstalk of stereoimages is increased. The performances of simulation and experimental display prototype show that the diazone of vernier fringe is faded and obviously sparser in the naked-eye LED 3D display. As a result, vernier fringe of this display is significantly decreased and not visible for viewing.
