    摘要: In a method of driving a light source, light generated by a light source is sensed in order to detect color coordinates of a red color, color coordinates of a green color and color coordinates of a blue color. A light source color space formed by the color coordinates of the red, green and blue colors is compared with a reference color space formed by red reference color coordinates, green reference color coordinates and blue reference color coordinates. Then, color temperature of the light generated by the light source is controlled so that the light source color space covers the reference color space.

    摘要: A light source apparatus includes light-emitting blocks, a local dimming control part and a light source driving part driving. The light-emitting blocks include a first-color light source which emits first-color light and a second-color light source which emits second-color light. The second-color light source includes a third-color chip and a fourth-color phosphor disposed on the third-color chip, and is disposed as one package to emit the second-color light therefrom. The local dimming control part compensates a driving current of the first-color light source and a driving current of the second-color light source of each of the light-emitting blocks. The light source driving part drives the first-color light source and the second-color light sources based on the driving current of the first-color light source and the a driving current of the second-color light source, respectively, each compensated by the local dimming control part.

    摘要: The present invention provides a side emitting lens that may reduce optical loss and improve light emitting ratios, and a backlight unit and liquid crystal display including the side emitting lens. The side emitting lens may have a substantially dome-shaped body. The body includes a base part on which external light is incident, a refracting part to refract incident light and emit the light from side surfaces, and a reflecting part. The reflecting part is in the shape of a conical recess at a central portion of the refracting part to fully reflect the incident light toward one of the refracting part and the base part and the reflecting part comprises two or more reflecting surfaces. Each of the two or more reflecting surfaces is a curved surface.
