Abstract

The disclosure provides a touch device and an operation method thereof. A touch panel of the touch device is divided into a plurality of stylus connection areas. During a first discovery period, the stylus connection areas detect a stylus one by one in a first scan order. When the stylus is located in one of the stylus connection areas (a hit area), the first discovery period is ended to enter a normal period, and the hit area establishes a connection to the stylus. When the connection between the stylus and the touch panel is interrupted, the normal period is ended to enter a second discovery period, and the first scan order is adjusted to a second scan order according to the hit area in the normal period. During the second discovery period, the stylus connection areas detect the stylus one by one in the second scan order.
