Abstract :
One glass single ITO layer solution has been demonstrated for large size projected-capacitive touch panels. Using simple touch sensors and algorithm, the proposed solution can effectively solve the issues of sensitivity reduction and large coordinate shifting existing in current large size touch panels. A touch system based on the proposed solution can achieve a coordinate shifting of less than 1.5%.
