We all remember overhead projectors from our science class. They were bulky
items of kit that took two of us to move from them from the store cupboard
to the classroom and we were warned not to jolt them as the bulb was
incredibly fragile and cost hundreds of pounds to replace. Terrifying – we
thought the bill would be sent to our parents so we would handle with great
These types of projector had one major failing – you could only use them
with acetate plastic and a dynamic presentation was essentially handled by
drawing live on the acetate with a felt pen. It didn’t make for very
exciting presentations and if you made an error on your finely printed
graphs – they stayed there until you could re-print.
The advent of the ink jet printer made it a little easier to cope with
because you could easily re-print, but that still meant a trip back to the
computer and it was pointless if you were in the middle of a class. What we
really needed was something that could project the contents of the screen
of a computer. By doing this we could finally get animation and vibrant
colours and maybe presentations and classes would be do dull.
The first attempts at this came when the TFT screen appeared. The
technology used in the very first flat screen panels was utilised to create
and essentially ‘transparent’ monitor that sat on top of a standard
overhead projector and meant we could finally show what was on our computer.
These were fantastic though for the IT trade who reveled in this new found
freedom of expression and when PowerPoint came along from Microsoft, people
were subjected to boring presentations for years. One of the biggest
problems though was with the brightness of the display. You simply could
not use these projectors with the lights on and many people were plunged
into darkness just to see some graphs on the wall.
Projector quality has thankfully increased dramatically though and it is
now perfectly possible to use them in full daylight or with full lighting
due to the extremely powerful bulbs powering these devices. They have also
become incredibly portable and you can now get hold of projectors that will
easily fit in your pocket. Stunning when you consider the brightness
required to get your work seen by the masses.
Even more technology is on the way though with rumours that a major mobile
phone manufacturer will soon be building a projector into a phone. This may
sound like a bizarre idea, but seeing as many mobile phones can now play
video, it looks like yet again the entertainment industry will be pushing
advances in the office marketplace very soon.
