Sheet-feed Control of LCD Glass Substrates with Stringent Quality Controls
Case Number 201
last update: April 1, 2008
Two-dimensional codes containing product information, lot information, serial numbers, etc., are printed directly onto LCD substrates using a laser marker or exposure device, and the 2-dimensional codes are read at each process.
This makes it easy to read direct marking, which is otherwise difficult to read.
The retrial function and bank function allow stable reading of codes that are covered by a film. This also provides a countermeasure for printing fluctuations.
System configuration and settings are easy, reducing the number of steps required for start-up.
Benefit / Efficiency
Each individual substrate can be managed, so more accurate history management is possible.
Created to meet real-world production site needs.
