Patent ID: 8073493

Claim:
A portable electronic apparatus, comprising: a casing having a first face and a second face; a first displaying module disposed on the first face of the casing; a second displaying module disposed on the second face of the casing; a communicating module for receiving an incoming call from outside, when the communicating module receives an incoming call signal, the communicating module generating a starting signal; a sensing module, coupled to the communicating module, when the sensing module receives the starting signal from the communicating module, the sensing module performing a sensing procedure to generate a sensing result; and a controlling module, coupled to the first displaying module, the second displaying module and the sensing module, the controlling module selectively displaying an incoming call information on the first displaying module or the second displaying module according to the sensing result, wherein the incoming call information relates to the incoming call signal, wherein the sensing result relates to a suitable reading face chosen between the first face and the second face, and the controlling module displays the incoming call information on the first displaying module or the second displaying module set on the suitable reading face, and wherein the sensing procedure is to sense which one is a brighter face between the first face and the second face by an optical way, and the suitable reading face is the brighter face.
