LED (Light-emitting Diode) displayer

The utility model relates to an LED (Light-emitting Diode) displayer which comprises a plurality of LED packages, wherein the plurality of LED packages comprise plastic shells, LED chips arranged in the shells and optical converting materials arranged in reflection cups. The optical switching materials convert at least a plurality of light emitted from the LED chips, and the plurality of LED packages emit the packaging light from the optical converting materials or emit the combinations of the packaging light from the optical converting materials and the light from the LED chips; the LED packages further comprise contrast regions; the contrast regions are arranged outside reflection regions and have colors forming contrast with the packaging light. The LED displayer has excellent contrast ratio between different pixels; meanwhile, the luminous flux or brightness sensed by the displayer cannot be reduced.
