Abstract
The apparent changes of color tones are suppressed by changing the characteristics of the voltage applied to the liquid crystal according to the switching-over of the light source intensity. Therefore, the disturbed color tones caused by a variation of the light source emission spectrum are compensated. The light source can be controlled practically, so that the liquid crystal display is sophisticated by implementing the power saving mode and extending the adjusting range of the contrast and bright levels.
