## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to portable electronic devices, particularly to a portable electronic device configured (i.e., structured and arranged) with a single printed circuit board.
2. Discussion of the Related Art
With the development of recent technology of information processing, portable electronic devices such as digital cameras, MP3 players, video cameras, mobile phone, and personal digital assistants (PDAs) are widely used. The developing trend of these portable electronic devices is to be light, thin, and small in volume.
A typical portable electronic device includes an upper shell, a keypad, a display, a battery, a circuit board, and a lower shell. The keypad and the display are formed adjacent to each other at one side of the circuit board. The battery is provided at the other side of the circuit board. However, such a portable electronic device has a relative large volume.
Therefore, a new portable electronic device is desired in order to overcome the above-described shortcoming.
SUMMARY
In one embodiment thereof, a portable electronic device includes an upper housing, a circuit board, a display, a battery, and a lower housing. The upper housing defines a display section therein. The circuit board has a top surface and a bottom surface at an opposite side of the top surface. The display is seen through the display section. The battery and the display are formed adjacent to each other on the top surface of the circuit board. The circuit board, the battery and the display are located in-between the lower housing and the upper housing. The upper housing is detachably attached to the lower housing for detachably holding the battery therein.
