← ScienceWhich mechanism allows LCD screens to display images?
A)Polarization shifts liquid crystal alignment✓
B)Refraction concentrates backlight intensity
C)Diffraction increases pixel angular separation
D)Interference creates constructive colors
💡 Explanation
Applying voltage orients liquid crystals because this changes transmitted light polarization; therefore only some light passes through the output polarizer, rather than different colors being directly generated.
