it all works
Monitor technology is based around a single tube in the back
of the monitor dubbed the Cathode Ray Tube, or CRT. Almost all
monitors use this tube, with the exception of flat-screen monitors,
commonly found on laptops. The Cathode heats up intensely, and
begins to defoliate electrons. The CRT is lined with a phosphorous
material that emits light when it is struck with electrons.
The material is arranged in the form of millions of tiny cells,
or dots if you will. If you were to look very closely at your
monitor with some magnification involved, you could see all
these dots. Towards the back of the monitor sit three electron
guns, which shoot streams of electrons at the screen. These
guns start at the very top of the screen and quickly scan from
left to right. Once they reach the right end of the monitor,
they drop down one row and repeat the operation. This is repeated
until the whole screen is drawn. While sounding somewhat slow,
this operation draws the whole screen in a fraction of a second.
Each of the three electron guns controls the display of a color,
red, green, and blue. This way, the full rainbow of colors is
available. The CRT surface only glows for a split second before
it begins to fade, requiring the screen to be constantly redrawn
many times per second to avoid having the screen flicker as
it fades and is redrawn.
electron guns shoot the streams through a lens dubbed the Elliptical
Aperture lens. Like the lens of a camera, it can be focused
to make a sharper image. Even though monitors ship focused for
sharpness, aging of the monitor can cause the lens to move slightly
and become out of focus. This is what causes a monitor to become
blurry, and lose its original crisp look.
your monitor can be potentially dangerous to the monitor, as
well as to you. Monitors have strong electric current running
through them and can be extremely dangerous if not handled properly.
We do not recommend opening your monitor casing, and changing
the settings inside. Only professionals who have experience
in monitor repair should touch the inside of a monitor. This
article is for informational purposes only, if you do decide
to open your case, please be extreme careful, as we are not
responsible for any damages caused by not heeding this warning.
