一种平板显示无缝拼接技术的研究

Seamless tiling technology based on FPD

针对平板显示技术最新进展和技术特点,提出利用光学移像技术实现平板显示屏无缝拼接显示的方法。采用隔行/隔列或分时显示技术,在平板显示屏邻近边框区域设置重叠显示区显示2幅图像,借用偏振光旋转装置与偏振反射膜,实现图像的分离。通过斜方棱镜将分离出的图像引导至显示器件边框位置覆盖边框,将原来36mm宽的拼接缝减小至3条不到0.5mm宽的棱镜拼接缝,实现了平板显示屏的无缝拼接。

Based on the latest development and technical characteristics of FPD technology,a method for producing seamless tiled FPD panels using optical image-shifting technology was put forward. Two image sections were displayed near the border of FPD panels by means of interlace frame display. The image sections were separated using polarizing rotation apparatus and polarizing beam splitter. The separated image section was moved by image-shifting prism to cover the border. The tiled seam width was reduced from 36 millimeters to three pieces of 0.5 millimeter wide prism seam. The seamless tiling of FPD panels was realized successfully with this technology.
