One of the most popular and must have items for the traveling salesman is
the Pico Projector. This pocket-sized gadget allows you to project
presentations from a portable media device. In my mind, the ideal
application of this technology is in a sales meeting. A Pico Projector is compact, about the size of a large cell phone, and can project up to
60″ with VGA resolution. Also, a pico allows you to quickly set up and
break down your presentation with ease. Some models like the Ray
Projections Pico Projector, even include a small, flexible tripod that
screws into the bottom of the device.
This technology was put into production back in 2009, however the concept
was introduced back in 2003. Typically these projectors will come with an
LED light source and uses a technology know as LCoS (Liquid Crystal on
Silicon) to produce a micro-display projection. Usually these handheld
projectors come with sufficient storage capability to handle media like
movies or presentation materials.
These gadgets consist of four main parts, the electronics, a laser light
source, the combiner optic and the scanning mirrors. Basically, the
electronic components turn the images into an electronic signal. Then the
signal drives the laser lights to produce different colors and intensities
down different paths. In the combiner optic the different light paths are
then combined into one path demonstrating a palette of colors. The mirrors
then copy the image pixel by pixel and then projects the image.
The biggest complaint about these projectors is the audio and picture
quality. Some of these devices do not come with built-in audio speakers,
meaning you would need to bring external speakers and the display works
best when in a dimly lit area with a projection screen.
A Pico Projector [http://www.raydisplays.com/] is a great presentation tool
and can also serve as your personal movie theater. With the capability to
project from a mobile device such as an iPod or iPhone, the capabilities of
Pico Projectors [http://www.raydisplays.com/meetray.html] are truly vast.
