Abstract

The present invention provides an illumination device and a method thereof to be applied on a display unit, such as liquid crystal display, of a portable electronic device where a program for activating operation modes switching needs to be pre-stored in the portable electronic device so that, when the portable electronic device receives a default signal, the portable electronic device can run the stored program for activating operation modes switching according to the default signal to generate a switching signal and control the display screen and backlight luminance of the display unit according to the switching signal. For example, in a condition when lighting is required, the portable electronic device can control the display screen of the display unit to exhibit a whole white screen and adjust the backlight luminance to maximum so that, without any additional illumination mechanism required, the portable electronic device with a display unit can provide the user with lighting in a dim environment.
