LCD Dead Pixels:
LCD, Liquid Crystal Display or Liquid Crystal on Silicon,
has been around for some time. This technology can be
commonly found in popular HDTVs, computer or laptop monitors
and Sony's new PSP. But the downside to LCD screens is
the dreaded "dead pixel" or "hot pixel"
phenomenon. Dead pixels or "hot pixels" are
defined as "a pixel on an LCD monitor that remains
unlit, or black, when it should be activated and displaying

What is an LCD Burn-In?
Images can be "burned" into an LCD panel
if left displayed for an extended or considerable
period of approximately 24 hours (depending on the
images and LCD). But since LCDs are different from
monitors with a cathode-ray tube (CRT), an LCD panel
can recover in time and disperses the image.
If your LCD monitor is having this problem, turn
off the display panel to allow recovery. To prevent
this from happening, make it a habit to set your
monitor display to automatically turn off if you
won't be using it for an hour or so.
Screensavers are exactly what they are: they save
the life of your screen or monitor. When your LCD
panel is in the screensaver mode, it keeps the display
backlight in use. However, bear in mind that putting
the computer to stand-by or shutting it down when
it won't be used for a long time is more efficient
and preferred to a screensaver.
Cleaning the LCD Screen:
- Turn off the computer or display. When cleaning,
make sure your LCD is unplugged, and if you
use a damp cloth, wait until the screen if completely
dry before turning it back on.
- Dampen a clean, soft, lint free cloth or paper
with water only.
- You may also use mild glass cleaner as long
as it doesn't contain alcohol or ammonia. Some
office or computer supplies stores carry cleaning
kits specifically designed for this purpose.
- Wipe the screen. Do not spray liquid directly
on the screen.
It is important that you read your owner's manual
or contact your LCD manufacturer to see what cleaning
and handling tips they recommend. Please remember
that while it is good to clean your LCD panel
every now and then, these screens are not designed
for constant touching. By doing so, you risk damaging
the pixels or having dead pixels within the LCD
screen so be very careful when cleaning your LCD
