Abstract
For general add-on touch panels, a touch-sensitive layer is attached to the outside of LCD panel. As the touch panel has a sensitive layer, it must be aligned with the display panel very well, the laminating precision is also required. The integration of this kind of equipment is complex, and the research and development of the equipments covers many topics of system integration. It is difficult to customize the products for different sizes or functions. This research used key technologies, including different space alignment design and unmarked alignment method, to create an easily operated image servo alignment system. Stable and rapid alignment results were obtained by parametric optimization. Finally, this module was applied to the industrial automatic laminating machine in practice for alignment and lamination.
