结构问题 显示器件乃是信息与人眼间联系的桥梁,人眼对可见光中各波长的响应不一致,因此感兴趣的便不只是发光的能量问题。这样,评价发光二极管便有两个重要的参数,第一个就是量子效率,简单的说来,所谓量子效率就是输出的光子数与通过PN结的电子数之比,也就是器件的转换效率,它是与 Structural problems show that the device is a bridge between information and the human eye, the human eye on the wavelength of visible light in the inconsistent response, it is not only interested in the energy issue of light. In this way, the evaluation of light-emitting diode has two important parameters, the first is the quantum efficiency, in short, the so-called quantum efficiency is the number of output photons and the number of electrons through the PN junction ratio, which is the conversion efficiency of the device, It is with
