Abstract
It is important to accurately align a pair of substrates, such as liquid crystal display (LCD) panels before they are affixed together. This is accomplished, according to the invention, by depositing a number of magnetic field generating elements on one substrate and a plurality of magnetic field-detecting elements on the other substrate. For example, the field-generating elements can be permanent magnets, while the field-detecting can be correspondingly located elements of a magnetic material. Alternatively, both the field-generating and field-detecting elements may be made from permanently magnetic materials.
