Abstract
A micro LED and a display module are provided. The micro LED includes a first semiconductor layer having a light emission surface and electronically connected to a first electrode; a second semiconductor layer electronically connected to a second electrode; an active layer disposed between the first and second semiconductor layers; and a wavelength conversion layer stacked on the light emission surface of the first semiconductor layer. The wavelength conversion layer is made of a semiconductor having a chalcopyrite-structure. The display module includes a plurality of such plurality of micro LEDs arranged in pixel units, which are electronically connected to a plurality of TFT electrodes. The module also includes a glass substrate and a TFT layer formed on one surface of the glass substrate, and the plurality of TFT electrodes are formed on the TFT layer. The resulting TFT layer does not require a color filter or a cover layer.
