You can’t choose the perfect liquid-crystal display (LCD) without considering the backlighting. All LCDs have backlighting. Unlike other display technologies — cathode-ray tube (CRT), plasma, etc. — LCDs don’t feature self-illuminating pixels. The pixels in LCDs must be illuminated from an external source. Known as the backlighting, it will create light that illuminates the LCD’s pixels.
Not all LCDs use the same type of backlighting, though. Some of them use cold-cathode fluorescent lamp (CCFL) backlighting, whereas others use light-emitting diode (LED) backlighting. Of those two backlighting technologies, CCFL is the most common. Nonetheless, more and more manufacturers are designing their LCDs with LED backlighting. The rise of LED-backlit LCDs such as this can be attributed to the following.
Lower Power Consumption
All LCDs consume power — and LED-backlit LCDs are no exception. When compared to CCFL-backlit LCDs, though, LED-backlit LCDs are more energy efficient. They consume about 20% to 30% less power than CCFL-backlit LCDs. This is due to the fact that LED-backlit LCDs feature LED bulbs, which are more energy efficient than CCFL bulbs. With their lower power consumption, LED-backlit LCDs have become increasingly popular.
Another reason LED-backlit LCDs are on the rise involves longevity. They tend to last longer than other types LCDs. It’s not uncommon for LED-backlit LCDs to last for tens of thousands or even hundreds of thousands of hours. Other types of LCDs, conversely, may fail long before this time. If you’re tired of constantly repairing or replacing your display devices, you may want to choose LED-backlit LCDs.
LED-backlit LCDs are lightweight. Some of them, in fact, weigh just half the weight of a standard CCFL-backlit LCD. This makes them easy to install as well as move. You can lift an LED-backlit LCD yourself, and you can typically install it without a second set of hands. All LED-backlit LCDs are lightweight, which is one of many reasons why they are on the rise.
Superior Contrast Ratio
You may discover that LED-backlit LCDs create more distinct and visible differences between their dark and light colors. This is because they have a superior contrast ratio when compared to other types of LCDs. The contrast ratio reflects the visible differences between dark and light colors.
LCDs are available in different backlighting technologies. Some of them use CCFL backlighting, whereas others use LED backlighting. LED-backlit LCDs are particularly beneficial. They consume less power, last longer, weigh less and other a superior contrast ratio.
