PIEZORESISTIVE TYPE TOUCH SCREEN PANEL

摘要

PURPOSE: A piezoresistive touch screen panel is provided to improve reliability through the reduction of the whole electrical resistance by being formed of a flexible electrode and a metal electrode and detecting coordinates based on a first and a second strip electrodes. CONSTITUTION: A substrate(10) includes holes(20) arranged while forming an orthogonal coordinates system and has a first and a second directions. A polymer membrane(30) is attached to the substrate, has a surface and the other surface, and changed according to stress. First strip electrodes(40) include a flexible electrode(42) arranged on the surface in the first direction, crossing over the holes, and changed with the polymer membrane and a metal electrode(44) placed between the holes to be connected with the first flexible electrode.
