Abstract
An inkjet printing system is provided, which includes a first stage mounted with a mother glass including a plurality of substrates and a plurality of alignment keys, a head unit having at least one inkjet head, an alignment key position sensor for sensing positions of the alignment keys to generate a plurality of sensing signals respectively corresponding to the alignment keys, and a transporting unit controller for aligning a position of the head unit based on a current position of the head unit and positions determined by the corresponding sensing signals with respect to the corresponding alignment keys.
Claims9
An inkjet printing system comprising:
- a first stage mounted with a mother glass, the mother glass including a plurality of substrates and a plurality of alignment keys;
- a head unit having at least one inkjet head;
- an alignment key position sensing unit sensing positions of the alignment keys to generate a plurality of sensing signals respectively corresponding to the alignment keys;
- a memory storing the sensing signals;
- and
- a transporting unit controller comparing a current position of the head unit and the sensing signal corresponding to positions of the alignment keys to align the head unit,
- wherein the alignment keys comprise a first alignment key disposed on a side of each of the substrates, and a second alignment key disposed on an opposite side of each of the substrates, the opposite side opposing the first alignment key with respect to each of the substrates.
