If marketing is to be believed, LED backlighting offers you all kinds of advantages, but it’s important to understand what is true, and what is not. We will discuss different aspects and whether they are influenced by a different backlight source:

W-LED backlit models are becoming more and more mainstrea. Initially the technology was combined exclusively with TN Film panels, since low production costs (and low retail costs) were the name of the game. There are many TN Film based models out there with LED backlighting now. More recently, in the later half of 2010, we have seen models emerge combining W-LED backlighting with VA and IPS matrices. AU Optronics have released modules in several sizes which combine their AMVA panel technology with LED, and LG.Display have begun to release a combination of IPS and LED. The BenQ EW2420 and VW2420H were two of the first VA based screens on the market with LED. The NEC EA232WMi and forthcoming models from LG will be some of the first to use IPS + LED. We expect this trend will continue.

At the professional end of the market where RGB LED backlighting is used, it is combined with high end panel technologies such as AMVA (from AU Optronics) or IPS (from LG.Display). These panel technologies are more expensive to produce than the widely used TN Film panels in the mainstream market. When you are using an expensive backlighting unit, it obviously should be paired with a higher-end panel though. In fact, modern RGB LED displays such as the HP DreamColor LP2480zx even use a one-of-a-kind true 10-bit H-IPS panel (not 8-bit +AFRC like some of the other modern “10-bit” screens). RGB LED models are few and far between though of course.

There’s been a significant growth in the monitor market when it comes to screens with LED backlighting. I wanted to provide an article which explains the technology in more detail as it is bound to become more and more widespread. The technology was originally quite expensive, but reduced production costs and improved manufacturing processes have allowed LED backlighting to be used in even the lower cost monitor market. We are now seeing an influx of new screens in all different sizes using LED backlighting, and it is also being combined with TN Film, VA and IPS panel technologies.
