Abstract: The conventional computers are not usable in dark, as the
user cannot see the keyboard to operate properly. But there are many situations
where the user may like to work on his computer under low light conditions,
such as, during nights, while traveling in flights/ trains having low lights, working
in the garden during evening etc. So it is necessary to provide some light to
the laptop to operate the keyboard under low light situations.
Luminescence of the keyboard is a desirable feature for
portable computers. There may be several methods to illuminate the keyboard,
the most crude may be carrying an external light and fixing at a point where it
can light the keyboard. But solutions like this are not very convenient. The
inventors have been looking for better solutions. This article analyses 6 patents
on keyboard illumination.
A good illumination system do not consume more battery, do
not increase the size and weight of the laptop, do not increase heat inside the
laptop box, and do not cost much to manufacture. The light should uniformly
illuminate the whole keyboard and should not throw light on other areas that
are not required.
