Correct option is B
An
LCD (Liquid Crystal Display) screen works on the principle of
polarization of light. The liquid crystal layer is sandwiched between two sheets that are
polarized in such a way that:
1. One sheet is
horizontally polarized.
2. The other sheet is
vertically polarized.
1. When light passes through these polarizers and the liquid crystals, the orientation of the light is controlled, enabling the display to show images.
