Differential sensing scheme is an improvement method from single-line sensing to cancel display or panel noise in touchscreen system. However, differential sensing method raised a multiple-touches cancelation issue. As a consequence, the recovery algorithm is invented to overcome those issues. This paper introduces several methods to implement differential sensing scheme with recovery algorithm to remove panel noise and white noise in touchscreen system.
