Abstract
A display system that includes a liquid crystal element, a backlight, an adjustment unit, a light source control unit, and a liquid crystal control unit. The light source control unit operates the backlight to change a light source luminance level of light. The liquid crystal control unit operates a first plurality of pixels of the liquid crystal element to display normal information with a normal tone level. The liquid crystal control unit operates a second plurality of pixels of the liquid crystal element to display emphasis information with an emphasis tone level. When an adjustment value changes within a predetermined changeable range, the luminance level gradually changes with a change of the adjustment value, the normal tone level gradually changes with the change of the adjustment value, and simultaneously the emphasis tone level is maintained to correspond to brightness equal to or greater than brightness of the normal tone level.
