Which functionality relies on polarization within LCD screens?

💡 Explanation

Liquid Crystal Displays use polarization to filter light emitted from the backlight passing only light aligned with the polarization axis; therefore, LCD contrast relies on controlling which light wave orientations reach the observer rather than altering intensity because backlights provide the luminance strength.
