Patent number: 7875478Abstract: A method for controlling the color contrast of a multi-wavelength light-emitting diode (LED) made according to the present invention is disclosed. The present invention includes at least the step of increasing the junction temperature of a multi-quantum-well LED, such that holes are distributed in a deeper quantum-well layer of the LED to increase luminous intensity of the deeper quantum-well layer, thereby controlling the relative intensity ratios of the multiple wavelengths emitted by the LED.
