Abstract

The invention discloses a white light emitting device and display device using the same. A white light emitting device, including a circuit board; a plurality of light sources mounted on the circuit board, each light source of the plurality of light sources configured to emit monochromatic light; a light converter spaced apart from the circuit board, the light converter configured to convert the monochromatic light emitted from the light sources to white light; and a compensator provided between the circuit board and the light converter, the compensator configured to convert the emitted monochromatic light to white light.

Description

technical field [0001] Exemplary embodiments relate to a white light emitting device that emits white light using a light source that emits monochromatic light, and a display panel including the same. Background technique [0002] Light emitting devices, such as light emitting diodes (LEDs), are optical semiconductor devices that emit light through the recombination of minority carriers (electrons or holes). Light generated by recombination of minority carriers is monochromatic light having a wavelength within a specific range. [0003] A method of generating white light includes using a plurality of light emitting devices emitting various monochromatic lights having complementary colors, and using one light emitting device and phosphors having complementary colors to the monochromatic lights emitted by the light emitting devices. [0004] When white light is synthesized using a plurality of light emitting devices, the color reproduction range can be widened. However, sinc...
