Abstract

The invention relates to a red light LED chip, a preparation method and a display panel. When the red light LED chip is prepared, a hole dispersion layer is formed by adopting an adhesive dispersed with nano metal wires, and the nano metal wires are at least uniformly distributed on one side, close to a red light epitaxial layer, of the hole dispersion layer, so that holes are uniformly dispersed on the whole surface of the red light epitaxial layer; and by using the excellent conductivity of the metal nanowires, electrons at an electrode are dispersed, electron aggregation is reduced, the electrons / holes are uniformly distributed all over the light-emitting surface of the red light epitaxial layer, and the light-emitting effect of the red light epitaxial layer is improved.

Description

technical field [0001] The technical field of LED of the present invention particularly relates to a red light LED chip, a preparation method, and a display panel. Background technique [0002] Due to the material of the epitaxial layer of the red LED chip, an ITO (indium tin oxide) layer must be placed on the P-type semiconductor layer, otherwise electrons will directly pass through the active layer from the P electrode to the N-type semiconductor layer by the shortest path At the N electrode on the top, resulting in uneven light output from the red LED chip. The ITO layer mainly plays a role of hole transport and hole dispersion in the red LED chip, and is used to disperse holes to the entire surface of the P-type semiconductor layer. But in fact, as a semiconductor material, ITO has an unsatisfactory hole dispersion effect, which in turn leads to the problem of poor light extraction effect of the red LED chip. [0003] Therefore, how to improve the effect of dispersing ...
