A combinational portable electronic device has a first electronic device having a display panel and a second electronic device having also a display panel. The first electronic device has an accommodating groove with a first connection interface provided therein. The second electronic device has a second connection interface. The second electronic device is installed in the accommodating groove of the first electronic device with the first connection interface and the second connection interface electrically connected together. When a function operation of the second electronic device (e.g., a PDA) is performed, the displayed frame data can be sent to the first electronic device (e.g., an electronic book reader or a web-pad) for display.
