Abstract
A protection circuit for a touch panel device includes a detection block and a protection block. The detection block is arranged for detecting occurrence of noise interference that affects touch event detection of the touch panel device, and asserting a protection signal when occurrence of the noise interference is detected. The protection block is arranged for enabling a protection mechanism for protecting the touch panel device from the noise interference when triggered by the asserted protection signal. Besides, a protection method for a touch panel device includes: detecting occurrence of noise interference that affects touch event detection of the touch panel device; and enabling a protection mechanism for protecting the touch panel device from the noise interference when occurrence of the noise interference is detected.
