Patent number: 7560314Abstract: A method of fabricating an active array color filter structure utilizes the difference between the surface properties of lipophilicity and lipophobicity. When inks are coated on an active array substrate, ink at the lipophobic areas on the active array substrate will be repelled naturally, so that the color filter pixels formed on the active array substrate naturally have contact vias, which facilitates the electrical coupling of pixel electrodes and switch elements. Since there is no aligning or laminating process required for the color filter substrate and the active array substrate during fabrication, no aligning errors will occur. Also, because the pixel electrode can extend to cover over the corresponding switch element, aggravation of the switch element is reduced.Type: GrantFiled: April 11, 2006Date of Patent: July 14, 2009Assignee: Industrial Technology Research InstituteInventors: Wan-Wen Chiu, Chao-Kai Cheng, Yuh-Zheng Lee, Fu-Kang Cheng
