Abstract

The invention relates to a light emitting diode light source and a display device. The light-emitting diode light source comprises a substrate, a reflection cup arranged on the substrate, a light-emitting diode chip located in the reflection cup and an additional light-emitting body, wherein the additional luminous body comprises red fluorescent powder and green fluorescent powder which are mixed,wherein the red fluorescent powder comprises nitride red powder with a 1113 crystal structure and an activating agent europium, a chemical formula of the green fluorescent powder is (Si, Al)3 (O, N)4:Eu. The light-emitting diode light source is advantaged in that a color gamut coverage rate test of the light emitting diode is performed, the test result shows that a color gamut coverage rate of the light emitting diode reaches 72% or above, compared with the prior art, the color gamut coverage rate of the light-emitting diode light source is remarkably improved.

Description

technical field [0001] The invention relates to the field of light source technology, in particular to a light emitting diode light source and a display device. Background technique [0002] Light-Emitting Diode (LED, Light-Emitting Diode), as a high-efficiency light-emitting source, has many characteristics such as environmental protection, power saving and long life, and has been widely used in various technical fields. [0003] With the advent and development of the third lighting technology revolution, incandescent lamps and halogen lamps are gradually replaced by LED light sources due to low light efficiency and serious energy waste. [0004] During the process of realizing the traditional technology, the applicant found that the color gamut coverage rate of the traditional LED light source is generally only about 60%, and the color gamut coverage rate is relatively low. Contents of the invention [0005] Based on this, it is necessary to provide an LED light source ...
