← ScienceWhich principle causes light attenuation in LCD screens?
A)Polarization through liquid crystal alignment✓
B)Refraction within the glass substrate
C)Diffraction around pixel array edges
D)Interference between backlight wavelengths
💡 Explanation
Light intensity dims in LCDs because electric fields modify liquid crystal orientation, impacting **polarization**. This alters the filtering of backlight, therefore controlling pixel brightness, rather than refraction effects from the glass substrate or diffraction.
