Abstract
An electroluminescent device for communication apparatus of mobile phone for informing an incoming call for carrying out a flashing effect on the mobile phone when such occurs. The device comprises an electroluminescent means and a controller circuit wherein the controller circuit includes a signal receiving unit, an electroluminescent means flashing and driving controller unit, and a driving unit being electrically connected sequentially; and the electroluminescent means is provided on the surface of mobile phone being electrically connected to the controller circuit. This also provides a personalized housing of mobile phone.
Claims1
An electroluminescent device for a mobile phone comprising:
- a controller including a signal receiving unit, an electroluminescent means flashing and driving controller unit, and a driving unit being electrically connected sequentially;
- and
- an electroluminescent means provided on the surface of the mobile phone being electrically connected to the controller circuit;
- wherein the electroluminescent device and the mobile phone have a common power source, the signal receiving unit being used for receiving signal of an incoming call, said signal receiving unit having a transistor which is activated when a signal with frequency range of 800-1,900 MHz is received thereby causing a capacitor to negatively trigger, the electroluminescent means flashing and driving controller unit having an end triggered to drive a plurality of transistors sequentially and therefore performing a switching periodically wherein each of the plurality of transistors is activated in a predetermined time frame while any of two adjacent time frames is spaced by a predetermined time, a driving signal being sent to a frequency changer circuit when a driving end of the electroluminescent means flashing and driving controller unit is activated, thereby creating flashing effect on the electroluminescent means is when an incoming call is received.
