Abstract

A portable electronic product comprising a main body, a display panel and a touch pad is provided. The main body comprises a top surface and a bottom surface, and the display panel is disposed on the top surface of the main body and electrically coupled thereto. Moreover, the touch pad is disposed on the bottom surface of the main body and electrically coupled thereto. Since the touch pad is disposed over the bottom surface of the main body, the display panel is not blocked while a user selects the functional options shown in the display panel. Furthermore, the user can control the portable electronic product without touching the display panel such that the damage of the display panel from frequent touching is avoided.

Claims
