TOUCH SCREEN DEVICE AND ADAPTIVE NOISE CANCELLATION FOR THE SAME CAPABLE OF PREVENTING THE DELAY OF UNNECESSARY POWER CONSUMPTION DUE TO THE APPLICATION OF AN ALGORITHM OF THE EXCESSIVE LEVEL

摘要

PURPOSE: A touch screen device and adaptive noise cancellation for the same are provided to increase noise cancellation efficiency by applying an optimum algorithm according to the kind of power.;CONSTITUTION: A power decision unit(210) determines the kind of power consumption to a touch screen device. The power decision unit sets up a power mode. A noise cancellation module(131) applies a noise cancellation algorithm corresponding to a set power mode. The noise cancellation module filters the noise of a touch signal.;COPYRIGHT KIPO 2012
