Selecting Among Combinations of RGB LED Wavelength by Pair Comparison
  DOI :  10.2352/CIC.2008.16.1.art00032  Published OnlineJanuary 2008

In this article, we compared the optical characterization of 8 LED modules with cold-cathode florescent lamps (CCFL) backlight module. It is well known that LED display became the main product in the field of panel display rapidly with its characteristics of green power, high color saturation, reliability, long life, and low cost, etc. But users strongly feel certain LED display is unnatural when specific RGB wavelength combination is chosen. So we performed the psychophysics experiment and find out the RGB combination as (636/535/455nm or 630/535/455nm) can have both high efficiency and good color image quality.
