Mirror Projection Aligners

Amid ever increasing screen sizes, LCD television sets have enjoyed a rapid surge in demand. Supporting the production of these products are Canon's mirror projection aligners, which are used to expose the LCD panels used to make LCD televisions. As the screen sizes for these TV sets has grown, so has the size of the glass substrates used to create them, resulting in the need for mirror projection aligners capable of achieving precise exposure patterning over wide areas. Canon mirror projection aligners, which can accommodate substrates measuring 2,160 mm x 2,460 mm, offer the world's largest full-field exposure size to support the efficient single-exposure production of 57-inch widescreen television displays.
