Two-dimensional codes containing product information, lot information, serial numbers, etc., are printed directly onto LCD substrates using an exposure device or laser marker, and the 2-dimensional codes are read at each process.
In locations where people are involved, a handheld reader is used.

Know-How

The handheld reader is ideal for use in cell production processes. Three-color (red, green, blue) coaxial LED illumination enables even workpieces that are covered with a film to be read. The monitor allows 2-dimensional code data to be read on-site.

Benefit / Efficiency

Individual substrates can be managed for more accurate history management.
