What's the difference between WLED and RGBLED displays?

On Dell's website, it lists displays as being "WLED" or "RGBLED". What is the difference between these two types of displays?

"Okay, I'll take a stab at the RGB question. The backlight of the screen used to be cold cathode type bulbs. Think super thin flourescents. The problem is that they were power hungry. The next generation used a white light LED to save on power. The problem is that there is no such animal as a white LED. The LED is actually a yellow LED with a blue coat. Sometimes that creates a slight shift in color. Slight yellow or yellow green tones are common. You display may show this shift with slightly off color images.

RGB uses pure color Red/Green/Blue LED's. When you focus them together, they create a true white light and this focused through the display should create brighter, truer colors."

WLED or RGBLED Displays are misnomers, the pixels are not LEDs but LCDs. So to be correct, we should have (if abbreviation must be used) LED b-l LCD Displays where b-l stands for back-light. Soon we should have 'true' LED Displays. What do you think?
