If you use your computer a lot, you probably try to keep up with the latest technology so that when it’s economically feasible you can upgrade to products that will help you complete your computing tasks quickly and make your free time using the computer as entertainment more enjoyable.
There are some new features that pique your interest, but even though you kind of….sort of….have an idea of what they are, you’d be hard pressed to explain them to someone else who was contemplating the purchase. You don’t want to admit that you paid a lot of money to upgrade to a LED backlit monitor because someone told you it was a good idea. You want to imply that you actually know what a LED backlit monitor is. Here are some of the basics.
LED means light emitting diode. LCD stands for liquid crystal display. Backlight is a source of light at the back of a display panel that illuminates the LCD from behind.
To make it even more confusing, OLED, or Organic LED doesn’t require a backlight to function, so that means the LED backlight LCD (called TFT) screens aren’t the same as OLED active screens.
So, do you really need a LED backlit monitor? They are more expensive that the traditional screens, but are they worth the extra expense?
The consensus by the experts is that the screens not only consume less power and produce more heat than the older monitors but are much more reliable. They have a longer life. The older monitors tend to lose brightness after a couple of years and start to dim.
The advantage for laptop users is that the life of the battery is longer simply because the LED backlit monitor uses less power. The width of the screens is also thinner which could mean that the weight of the laptop is less. Those of us who carry our laptops everywhere we go can see the advantage of that.
Shop and compare the features of the LED backlit monitors that are available on the market. Understanding the meanings of all the letters that are strewn through the promotions will help you make a better decision.

LED Backlit Monitor Technology Advancements
Monitor technology changes almost as quickly as computer technology itself does. Keeping up with everything there is to know about monitors is a full time job. Most people have no idea what goes into the monitors or what the differences are. Today, most monitors rely on LED backlight monitor technology and for good reason. Here are some of the benefits of LED backlight monitors.
Color Gamut and Accuracy
LED backlight monitors have high color gamuts, the range of colors that the monitor can achieve, which are controlled by the unit’s color filters and the spectrum of the backlight’s radiation. LEDs can hit as high as 114 percent.
Accuracy depends, to a large extent on the ability of the display to produce a high color bit depth. The number of steps of color within that range is determined by bit depth. A monitor with a 10-bit panel can, in theory, produce up to 1.07 billion varied colors. Most monitors use 6-bit panels which translate to about 262,000 colors. Technology has allowed some to use techniques that “fake” as many as 16.2million colors.
Size
Monitors with EL-WLED backlights are thin in size as compared to using RGB LED technology which employs better color performance. RGB LEDs can be much bulkier and more expensive than their EL-WLED counterparts which, while not as good in the color department are less than 1 inch thick.
Power Usage
The EL-WLED backlights consume less power than traditional monitors. This is influenced by the size of the screen and it luminance.
Disposal Issues
CCFL technology used in older monitors relied on mercury. This toxic substance made disposing of these dinosaurs more problematic. There is no mercury in any of the LED-base monitors making them much easier to recycle and dispose of.
While you may have to choose between top of the line color performance and size, LEDs in general will give you better color ranges than anything else currently available. Lower power consumption and environmentally –friendly when it’s time to dispose of them in addition to enhanced color performance are the main reasons to consider an LED backlight monitor when you are ready to replace your current monitor.
