First Claim
1. A portable communication device, comprising:
- a keypad comprising a plurality of numeric keys and an LED driver, each of the numeric keys equipped with a first color LED light and a second color LED light; and
a telephone dialing system comprising one or more programs that is stored in a storage system and executed by at least one microprocessor, the one or more programs comprising;
an initialization module that drives the first LED to light under each of the numeric keys to emit a first color light using the LED driver when a user inputs a first digit of a phone number from the keypad;
a number obtaining module that receives a digit inputted from a numeric key of the keypad, searches all phone numbers having the inputted digit in a phone number list stored in the storage system, obtains a subsequent digit following the inputted digit from each of the phone numbers, and generates a digital group according to all the subsequent digits; and
an LED control module that generates an LED control signal according to the digital group, drives the LED driver to turn off the first LED light under the numeric key in digital group and turn on the second LED light under the numeric key to emit a second color light according to the LED control signal, determine whether a next digit input from the keypad is in the digit group, and drives the LED driver to turn off the second LED light under a numeric key corresponding to the next inputted digit and turn on the first LED light under the numeric key to emit the first color light when the next inputted digit is in the digital group.

Abstract
In a method for dialing phone numbers using a portable communication device, the device includes a keypad including numeric keys and an LED driver. Each of the numeric keys is equipped with a first color LED light and a second color LED light. The LED driver drives the first LED light under each of the numeric keys to emit a first color light. The LED driver turns off the first LED light under the numeric key and turns on the second LED light under the numeric key to emit a second color light according to an LED control signal. The LED driver further turns off the second LED light and turns on the first LED light to emit the first color light when the digit input from the keypad is in a digital group.
