Which principle causes light attenuation in LCD screens?

💡 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.
