Latest Patents

Chih-Feng Lu holds a patent for a "Method for controlling color contrast of a multi-wavelength light-emitting diode." This invention involves a technique to increase the junction temperature of a multi-quantum-well LED. By doing so, it allows for a better distribution of holes in a deeper quantum-well layer, which in turn increases the luminous intensity of that layer. This method effectively controls the relative intensity ratios of the multiple wavelengths emitted by the LED. The adjustment of the junction temperature can be achieved by modulating the thickness of the p-type electrode layer or by modifying the mesa area size to manage the heat radiation surface area.
