Abstract
A touch panel includes a TFT array having a plurality of thin film transistors; a plurality of signal lines disposed within the TFT array, each of the signal lines being electrically connected to a respective one of the transistors; a transparent conductive pattern layer disposed above the plurality of signal lines and electrically connected to each of the transistors; a flexible conductive layer; and a spacing pattern layer supporting flexible conductive layer to space the flexible conductive layer apart from the transparent conductive pattern layer. When pressure is applied onto the flexible conductive layer, the flexible conductive layer contacts the transparent conductive pattern layer to transmit an electrical signal via the signal lines into the TFTs to indicate the point of contact.
