The backlight module includes a back plate; a light-emitting chip formed on the back plate and capable of emitting light rays of a first color; a packaging entity made of a light-transmitting material and configured to package the light-emitting chip onto the back plate; and a phosphor layer formed in the packaging entity and consisting of phosphors doped in the packaging entity. The phosphor layer is configured to convert a part of light rays among the light rays of the first color emitted from the light-emitting chip into light rays of a second color, so as to be mixed with the remaining, unconverted light rays of the first color to form white backlight."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Backlight module and display device","description":"The present invention provides a backlight module and a display device.
