Abstract

The invention provides a Mini LED packaging method and a Mini LED prepared through the method. A package support is set in a "Z"-shape structure; after package molding, photoelectric detection is performed; then, array arrangement is carried out to form a required patterned Mini LED light-emitting module, and yield is good; the "Z"-shaped structure is easy to assemble, that is, a second pin portion and a first pin portion of adjacent lamp bead units are overlapped and cooperated and are in electrical connection; the connection structure is compact, density is good, arrangement size is accurateand no deviation is caused; and chip package can be carried out without arranging an electrode on a substrate, so that the limitation of the substrate electrode is eliminated, and free arrangement isachieved.

Description

technical field

[0001] The invention relates to the field of semiconductor lighting and display, in particular to a packaging method of Mini LED and the Mini LED prepared by the method. Background technique

[0002] Mini LED refers to a display screen that uses more precise devices and new packaging methods to achieve 0.2-0.9 mm pixel particles. With the decline of LED chip costs and technological progress, coupled with the recent sluggish growth of the LED lighting industry, LED chip and packaging giants at home and abroad have begun to look for new market growth points. At present, Micro LED is difficult to be commercialized on a large scale in a short period of time due to the uncertain technical route and high cost. Mini LED, as an extension of small-pitch LED products and a prelude to Micro LED, has begun to be used in LCD Backlight and RGB display products were shipped.

[0003] Traditional Mini LEDs generally use cob (chip On board) packaging, which is to directly p...
