A back light unit includes a first light source which generates first light in a first wavelength range, a second light source which generates second light in a second wavelength range, and a first wavelength compensating part which adjusts a wavelength of the first light controlling a driving current, which is applied to the first light source.
摘要:
A backlight assembly includes a light emitting portion, a chromaticity converter and a light guide plate. The light emitting portion generates a first light. The chromaticity converter receives the first light, and converts a chromaticity of the first light to generate a uniform light having a uniform chromaticity. The light guide plate includes an incident surface to which the uniform light is incident, and a light exiting surface guiding the uniform light provided from the incident surface and emitting the uniform light. Accordingly, a display quality of a display apparatus may be enhanced.
