Abstract
A digital electronic apparatus includes a touch display panel, an active touch pen and a power shortage reminding module. The active touch pen is suitable for inputting signals to the touch display panel. The power shortage reminding module is disposed in one of the touch display panel and the active touch pen. The power shortage reminding module is suitable for monitoring a remaining power of the active touch pen and prompting the touch display panel to send out a reminding signal for charging the active touch pen, and therefore, the active touch pen can be timely charged, which prevents the power of the active touch pen be exhausted in use.
