Claim Text:
1. A projected capacitive touch panel, comprising: a substrate that is transparent and has a top, a bottom and four sides; an X-axis electrode layer formed on the top of the substrate and having a plurality of X-axis signal transmission lines formed on the top of the substrate and being adjacent to one of the four sides; a Y-axis electrode layer formed on the bottom of the substrate and having a plurality of Y-axis signal transmission lines formed on the bottom of the substrate and being adjacent to one of the four sides, wherein the X-axis electrode layer and Y-axis electrode layer together define a touch control area, the X-axis signal transmission lines and the Y-axis signal transmission lines are formed on a peripheral area that is out of the touch control area, and the X-axis signal transmission lines are formed on the side that is adjacent to that of the Y-axis signal transmission lines are formed on; an X-axis conversion module electrically connected with the X-axis signal transmission lines, the X-axis conversion module having: a Y-axis conversion module electrically connected with the Y-axis signal transmission lines and having: a control module directly connected to the X-axis conversion module through a first transmission cable without intervening functional components and directly connected to Y-axis conversion module through a second transmission cable without intervening functional components, the control module configured to compute and determine coordinate data from the digital signals, and to output the coordinate data, wherein the control module is external to the X-axis flexible printed circuit board and the Y-axis flexible printed circuit board, wherein the X-axis conversion module and the Y-axis conversion module are configured to convert analog signals into digital signals and are unable to compute or determine coordinates.
