Abstract

Different fabrication methods, such as chemical process, laser heating method, etc., can be used to make micro-retarder plates. In this paper, a CO₂ laser scanning system is applied to produce a serious of line patterns on the commercial compensator (or the retarder film, such as PC film, PVA film, or Arton film, etc.) to make micro-retarder plates, which are important optical components in stereoscopic 3D displays. Our study is focused on the development of high quality fabrication method, for example, the relationship of a well-defined stripe boundary with the CO₂ laser process under single beam or multiple beams. The laser scanning system in this paper is installed with an orthogonal pair of precise translation stages, a steadily controlled laser power output, and an adjustable spot-size optical head to make patterns of micro-retarder plates for stereo-LCTVs up to 42 inches.
