摘要: | 近年来众多日新月异的显示技术大多有各自的擅长的领域。在大尺寸显示技术中,背投影电视市场迅速的膨胀,特别是LCoS技术是广被看好的一颗新星。对量产及降低三片式微显示面板光学引擎成本而言,合光模组制程技术的改善是非常重要的工作。本研究的动机为分析与解决现行的LCoS系统三片式架构合光(alignment)模组的生产瓶颈。本论文提出了一个新的合光调整机构设计概念,以使光机的合光调整制程技术更具量产性。 本文利用了光学模拟技术研究三片式微面板之六轴合光的公差需求与成像品质之关联,以及针对公差的要求与机构理论设计出新的合光架构,并对新设计进行了实际制作、组装与调整等相关功能测试。最后针对合光模组进行了LCoS Panel温度测试、四分之一波板(QWP)旋转调整操作测试、Panel防尘测试、格线合光测试以及对焦测试等规格测试与分析,测试结果也显示了新合光调整机构设计概念的可行性。 Recently, many different new display technologies are approved in the specific applications. For large size display, the market size of rear projection TV is being increased fast, especially LCoS technology is the nova of the field. For mass production and cost down of the optical engine using 3 micro-display panels, improving the technology of panel alignment is very critical. The purpose of this thesis was to analysis and resolves the bottleneck of production of panel alignment module in LCoS 3 panels’ architecture. The new mechanic design concept of panel alignment was proposed in this thesis, which can improve the alignment technology in production obviously. The optical simulation technology was used for studying the tolerance requirements of the panel alignment in 6 axes first, and then the tolerance was used to design the new mechanic alignment parts with the new concept. All parts have been made and assembled as the new alignment module. Finally, the functions of the module were tested; included LCoS panel temperature, Quarter Wave Plate (QWP) adjustment function, dust-proof test, alignment, and focusing test. The experiential results shown that the modified module is effectively to improve the alignment technology for mass production and cost down. |
