Publication number: 20090109068Abstract: A touch control input device includes a flexible dielectric touch plate disposed above a dielectric substrate. A conducting unit includes first conductive membrane patterns formed on a top surface of the substrate and spaced apart from each other, and second conductive membrane patterns formed on a bottom surface of the touch plate and corresponding respectively to the first conductive membrane patterns. A spacer is disposed between the substrate and the touch plate for spacing each first conductive membrane pattern apart from the corresponding second conductive membrane pattern. Pressing of the touch plate so that at least one first conductive membrane pattern electrically contacts the corresponding second conductive membrane pattern results in outputting of an input signal by the conducting unit. One of the substrate and the touch plate is formed with a predetermined pattern that is visible from above the touch plate.Type: ApplicationFiled: October 27, 2008Publication date: April 30, 2009Inventors: Chih-Hsien Yeh, Chih-Ching Hu, Jeremy Casey Liu
