Abstract

The present invention is a method for controlling and emitting backlights of a mobile communications terminal in various operation mode according to a type of interrupts by allocating and coupling general purpose input output of a MODEM chip with each backlights of the mobile communications terminal and controlling each backlight individually. The method for controlling backlights of the0 mobile communications terminal, including steps of: a) detecting various interrupt generated by any operation of the mobile communications terminal; and b) controlling and emitting the backlights individually in a preset operation mode according to the interrupt detected at step a).

Claims (18)

1. A method for controlling backlights of a mobile communications terminal, comprising steps of:

a) detecting various interrupts generated by operations of the mobile communications terminal;

b) analyzing the detected interrupts and generating a controlling signal representing a state of the mobile communication terminal; and

c) controlling the backlights individually according to the control signal,

wherein the step c) includes the steps of:

c1) selecting as preset operation mode according to the control signal; and

c2) emitting the backlights individually according to the selected preset operation mode,

wherein the preset operation mode includes:

a first operation mode for turning all backlights off in an initial state;

a second operation mode for turning all backlights on in a key input state which represents occurrence of keypad input;

a third operation mode for sequentially turning each of backlights in a clockwise direction in a call receiving state which represents receipt of calls;

a fourth operation mode for sequentially turning backlights on and off in a downward direction in a file downloading state which represents downloading files;

a fifth operation mode for sequentially turning backlights on and off in a upward direction in an Internet state which represents access of Internet; and

a sixth operation mode for randomly turning backlights on and off in an ending state which represents turning off of the mobile communication terminal and a call drop state which represents call dropping.

2. The method as recited in claim 1 , wherein the various interrupts are generated in cases of opening a folder of the mobile communications terminal, entering no keypad input during a certain time, receiving a telephone call, receiving a message or e-mail, downloading a file, uploading a file and closing the folder of the mobile communications terminal.

3. The method as recited in claim 1 , wherein the preset operation mode defines backlight operating schemes including an order of turning each backlight on, an order of turning each backlight off and a duration time for emitting the backlights according to the control signal representing the state of the mobile communication terminal, wherein the present operation modes previously are set by a user of the mobile communications terminal.

4. The method as recited in claim 1 , wherein each of the backlights is connected to general purpose input output (GPIO) ports in a one-by-one manner and each of the backlights is individually controlled.

5. The method as recited in claim 1 , wherein the number of the backlights is 6.
