    摘要: A display system, method and backlight unit for use with a display. The backlight unit includes a first light source and a second light source, wherein the first light source and the second light source are controllable independently of each other. The sum of light produced by the light sources illuminates the display to achieve illumination brightness capability of a higher intensity capable single light source. Changes in spectral characteristics and/or brightness characteristics due to aging or the like may be compensated. The first light source may provide a base line illumination level for the display and the second light source may be modulated to dynamically increase contrast and/or contrast ratio characteristics of the image being shown on the display to a viewer.
