Abstract
A touch display apparatus is disclosed. Without additional touch device, either the reversed AM structure or a conventional PM structure is provided to combine with the human body's conductive properties and the noise-immune sensing circuit design, thereby to achieve the purpose of displaying images and performing multi-touch detection simultaneously. Thus, the hardware cost and the power consumption are reduced.
