Bright Future Ahead
A new & upcoming technology that is making its
transition from high-end HDTVs to PC monitors is the use of LED (light-emitting
diode) backlighting in LCD monitors. Most LCD monitors use CCFL (chilled
cathode fluorescent lamps) in their backlight, which although adequate for
illuminating the screen, cannot be exactly & individually controlled like
LEDs. What this means is that PC monitors with LED backlighting have a contrast
advantage, as specific LEDs can be dimmed in darker areas of a scene whilst others
can be illuminated even more in bright areas. Some manufacturers are also
experimenting with colored LED backlighting (i.e. red, green & blue than
white) to further increase the color gamut of the monitor; but some think that
the variable degradation of these LEDs over time will lead to bleaching or
over/under saturation of colors.
As with the first generation of 120Hz 3D monitors, LED
backlighting is definitely an technology in require of some refinement as it
matures. Although color reproduction & contrast in LED-backlit PC monitors
is excellent, in point of fact the differences are not immense compared to new
& comparable CCFL-backlit PC monitors. They do consume less power & are
thinner & lighter than their CCFL-backlit cousins, however, which is
definitely a bonus. They expect the LED backlighting technology to evolve &
for the changes to become more significant & upgrade-worthy over time &
PC Monitors will of coursework follow this technological trend in the future.
Note: LED backlighting currently involves strips of white
LEDs (known as edge-lit) & brings some efficiency & environmental
benefits without altering the picture. As they have explored there is
alternative implementations that may gain ground in the near future.
On October 22nd 2009, Microsoft launched the Windows 7
operating method & embraced a used technology already made popular by the
likes of smartphones & MP3 players. By offering touch screen support with
recognition of multiple finger gestures (multi-touch), Microsoft opened the
door for users & offered them a novel way to interact with their PCs. A flurry
of touch-screen PC monitors followed the launch of Windows 7, but of coursework
the technology is far from ideal. The most obvious issue with a touch screen
display is that you are touching it; so it gets greasy & grubby to such an
extent that cleaning becomes a frequent necessity. It seems, however, that to
keep the product at a reasonable size & price-point, that the technology
inside the touch-screen monitor resembles that of a basic TFT monitor, with the
touch-screen being the main feature. So don't expect amazing contrast ratios
& amazing dancing colors dashing vibrantly across the screen at least, not
today.
