Light-emitting diode (LED) display devices have become increasingly popular in recent years. You can now find TVs, computer monitors, smartphones, tablets and even human machine interfaces (HMIs) featuring LED technology.
With that said, the term “LED display device” is somewhat confusing. Based on the name alone, you may assume that they produce images using LED technology. While LED display devices are characterized by the use of LED bulbs, though, they typically rely on a separate type of display technology to produce images.
What Is an LED Display Device?
An LED display device is a flat-panel display that uses LED bulbs for backlighting. In other words, they contain an array of embedded LEDs that, when activated, produce light to illuminate the pixels. LED display devices don’t necessarily feature LED pixels. Instead, they use an alternative form of pixel technology, such as liquid-crystal display (LCD).
Most display devices are powered by LCD pixel technology. However, some of them use different backlighting technologies than others. In the past, LCDs used cold-cathode fluorescent lamp (CCFL) as the primary backlighting technology. In recent years, though, more and more manufacturers have switched to LED backlighting. LCDs that use LED backlighting are often referred to as an “LED display device” or an “LED-backlit LCD.”
Benefits of LED Display Devices
LED display devices offer many advantages when compared to other display devices, one of which is a wide color gamut. Color gamut, of course, refers to the range of brightness and darkness that a display device is capable of producing. With a wide color gamut, LED display devices are capable of producing brilliant images with rich color.
In addition to a wide color gamut, LED display devices are energy efficient. When compared to CCFL-backlit LCDs, an LED-backlit LCD is about 20% to 30% more efficient. Over the course of several years, that translates into substantial cost-savings benefits.
LED display devices are also lighter and slimmer than other display devices. This alone makes them an excellent choice for smartphones and mobile devices.
In Conclusion
An LED display device is a flat-panel display that uses LED backlighting. They are typically powered by LCD technology, which is responsible for creating the pixels. The LEDs simply illuminate the display device’s pixels, resulting in the creation of images. LED display devices offer a wide color gamut, energy efficiency, and they are both lighter and slimmer than other display devices.
