Abstract
A light emitting element, used behind a display, comprises LED chips emitting blue light and separated red and green phosphor layers on the LED chip, the layers receiving the emitted blue light and respectively converting the same into precise colors for the display. A portion of the light directly from the LED chip is also combined with the converted light and passed on as lighting for the display. Partial absorption of green light by the red phosphor and red light by the green phosphor, occurring when the red and green phosphor layers are overlapped, is avoided. Light conversion efficiency of the green and red phosphor layers is thereby improved. A light emitting assembly, a display device, and a method for making the light emitting assembly are also disclosed.
