Patent ID: 11264535

Abstract:
An LED has: a substrate formed as a substrate layer; a buffer layer formed on the substrate layer; and an N− doped layer formed on the buffer layer. A first dual color blue/green MQW active region, a negative electrode, and a second dual color blue/green MQW active region formed on the N− doped layer. A first P− doped layer is formed on the first dual color blue green MQW active region. A second P− doped layer is formed on the second dual color blue green MQW active region. A first P+ doped layer is formed on the first P− doped layer. A second P+ doped layer is formed on the second P− doped layer. A first positive electrode is formed on the first P+ doped layer. A second positive electrode is formed on the second P+ doped layer. A blue/green LED with red luminescence materials emits a full spectrum.
