Glass panel of Touch Screen Panel is thin and light then it is worthy of applying it to make the device more compact, and this structure has superiority in touch sensitivity. Followed tempered glass integrated TSP technology has some difficulty in implement stable ITO pattern soundness by the discrepancy of the height between the screen printed decoration layer and the ITO coated layer. Also, Gravure offset printing replaced with screen printing allows cost reduction but, more fine pitch implementation upon the bezel is not possible. Then here using BM(Black Matrix) to make window glass decoration layer by the process steps of cleaning, coat, vacuum dry, bake has been developed. After all, 300∼500Å ITO coated thickness has no dislocation opend, cracked area upon the BM after is finally cured thickness of 1.2∼1.4㎛, so as to make 5∼10㎛ BUS line pattern upon the BM bezel area. Then, this subject deals with the effective BM glass substrate fabrication process.
