Abstract

The invention provides a light emitting diode module, a display array and a manufacturing method thereof, which belong to the technical field of semiconductors. The light emitting diode module comprises a circuit board and a cylindrical pixel unit, and the pixel unit is vertically arranged on the circuit board; radial isolation grooves are formed in the pixel unit, and the pixel unit is divided into a plurality of fan-shaped light emitting structures by the isolation grooves; the light emitting structure belongs to one of a red light chip, a green light chip and a blue light chip, the plurality of light emitting structures comprise a light emitting structure belonging to the red light chip, a light emitting structure belonging to the green light structure and a light emitting structure belonging to the blue light chip, and central angles between two adjacent light emitting structures belonging to the same chip are equal. Thus, the uniformity of light emitted by the pixel unit can be effectively improved, and the light emitting effect of the pixel unit is improved.

Description

technical field [0001] The present disclosure relates to the technical field of semiconductors, in particular to a light emitting diode module, a display array and a manufacturing method thereof. Background technique [0002] Light Emitting Diode (English: Light Emitting Diode, referred to as: LED) is a commonly used light emitting device, which releases energy and emits light through the recombination of electrons and holes, and is widely used in the fields of display, decoration, communication and lighting in daily life. By adopting different semiconductor materials and structures, light-emitting diodes can cover the full-color range from ultraviolet to infrared, and basically occupy the large-pitch display market both indoors and outdoors. Wherein, the spacing refers to the distance between two adjacent display units in the display, which is related to the resolution of the display. [0003] Currently, liquid crystal displays (English: Liquid Crystal Display, LCD for sho...
