    LED Display - is it RGB LED? Is it side lit or back lit?

    Quote from Diggsby:

    RGB LCD with LED backlight. It is not an OLED display, which is a common source of confusion (OLED vs LCD, LED backlight vs CCFL).

    Hmmm ... my origin question was not too clear.

    I meant to ask:

    1. if the LED backlight uses "RGB/tri-color" LEDs or just "white" LEDs (as in the MacBooks).

    2. if the LED backlight on the edge of the display or the back of the display.

    LG makes a 1920x1200 17.1" LCD panel, LGD01b3, with RGB LED backlight, edge-lit. The LGD01b3 display has a wide color gamut, high contrast with vivid colors but suffers from non-even backlight color (I call it "wild gamut" because I can never get the color profiling right).

    Cannot find any info on this LM270WQ1 LCD panel and was hoping that the Teardown guys can tell if the backlight uses RGB LEDs and if the panel was edge-lit.

    This LCD panel is IPS and if it also uses RGB LED, then the iMac 27" is really a price break through!

    But on second thought, went through the specs and never see "wide gamut" being mentioned -- so likely at this price point, it is likely just a white-LED backlight.
