Publication number: 20070164400Abstract: A substrate structure includes a substrate and a number of banks formed on the substrate. The banks and the substrate cooperatively define a number of accommodating rooms. The accommodating rooms are configured for accommodating ink. A spread-control layer is formed on the substrate beneath the accommodating rooms. The spread-control layer enables the ink applied on the spread-control layer to spread at a lower spreading rate than the rate on the substrate without the spread-control layer formed thereon.Type: ApplicationFiled: September 12, 2006Publication date: July 19, 2007Applicant: ICF Technology Co., Ltd.Inventors: Ching-Yu Chou, Yen-Huey Hsu, Wei-Yuan Chen
