Patent ID: 11121172

Abstract:
A light-emitting diode unit for a display including a plurality of pixels each including: first, second, and third light-emitting cells respectively including a first conductive semiconductor layer, an active layer, and a second conductive semiconductor layer; pads electrically connected to the first through third light-emitting cells to independently drive the first through third light-emitting cells; a first wavelength converter for converting a wavelength of light emitted from the first light-emitting cell; and a second wavelength converter for converting a wavelength of light emitted from the second light-emitting cell, in which the first wavelength converter converts a wavelength of light to a longer wavelength than the second wavelength converter, the second light-emitting cell has a greater area than the third light-emitting cell, and the first light-emitting cell has a greater area than the second light-emitting cell.
