Abstract: Three sets of LED layers each include p-doped and n-doped layers with an active layer therebetween, a tunnel junction layer against the p-doped layer, and an additional n-doped layer against the tunnel junction layer. The first and second LED layer sets are separated by a first semi-insulating semiconductor layer; the second and third LED layer sets are separated by a second semi-insulating semiconductor layer; the second LED layer set is between the first and second semi-insulating semiconductor layers; the third semiconductor layer set is between the second semi-insulating layer and a dielectric layer. Cathode contacts extend through the dielectric layer to the n-doped layers; anode contacts extend through the dielectric layer to the additional n-doped layers. The three LED layer sets can independently emit light at three different corresponding wavelengths, e.g., red, green, and blue light that can encompass an sRGB color gamut or can yield white light.
