Abstract
Disclosed are an LED light source, an LED light source manufacturing method, and their direct display device. The LED light source includes a base, at least an LED chip, an anti-vulcanization structure, a light excitation structure, an encapsulation structure and a protection structure. The LED light source can overcome catalyst poison or vulcanization of the light-emitting material effectively to improve product yield and reliability of the LED light source. In the meantime, the LED light source has the feature of a better light emission performance.
