Abstract
In this study, organic wavelength-converting films (WCFs) applied to InGaN blue LEDbased
hybrid planarWLED has been fabricated. The organic dye layer in theWCF was formed between
the upper and bottom polymer sheets by using a simple roll-laminating technique. Subsequently, the
hybrid planar WLEDs have been fabricated based upon these films. The luminous efficiency of green
WCF-based hybrid planar WLEDs with a single blue LED chip was 34.6 lm/W and that of red-WCFassisted
green WCF-based hybrid planar WLEDs was 27.3 lm/W under 20 mA. The use of WCF to
fabricate hybrid planar WLEDs showed better stability than that of directly coating organic color-convergence
materials (CCMs) on the LED chips. It only decreased to about 10%of the initial wavelengthconverting
intensity after 1 hour of continual operation at 20 mA.
