Latest Patents

Sang Youl Han holds a patent for a force-sensing touch screen input device. This device is a solid assembly of multiple layers, including a display with a touch-sensitive external surface. It features a first and second electrode layer separated by a compressible dielectric structure, forming a capacitive force-sensing array. The design allows for one or both electrode layers to be formed by metallizing a polymer surface of the rigid substrate or by creating a conductive electrode onto an internal surface of the display. To increase reliability, each layer is permanently adhered to or formed onto an adjacent layer over its entire surface, preventing internal shifts. Additionally, the cover glass flexibility, compressible dielectric structure, and gasket structure are selected to provide elastic compression and recovery during normal operating conditions, enhancing response time.
