← ScienceWhich consequence occurs when a liquid crystal display (LCD) has reduced drive voltage?
A)Reduced contrast ratio appears✓
B)Faster pixel update frequency arises
C)Increased backlight energy emission
D)Display shifts towards ultraviolet hue
💡 Explanation
Reduced drive voltage affects liquid crystal molecule orientation. This means Polarization rotation is less effective, because fewer crystal molecules align correctly. Therefore contrast decreases, rather than color shift as voltages diminish.
