    I think the touching screen has a light sensor. You can test it out, if you face the screen onto a lamp, it will try to be lighter than the lamp. If is in the dark, it will darken.

    I found out that it took 10 second for me for the light to lit up, but to turn off it took a while...

    Everytime you unlock your iPhone from the lock screen, it redetect the light level. So, if you want it to go bright straight away, just press the lock key and unlock it back... Depending where you are, it will either go lighter or dimmer.
