Liquid crystal displays make use of
A)interference.
B)diffraction.
C)specular reflection.
D)diffuse reflection.
E)polarization.

Question

Quizplus · Accepted Answer

Liquid crystal displays employ polarization of light to control the amount of light passing through the display. When a voltage is applied, the liquid crystal molecules rotate, which changes the polarization direction of the light passing through the display. This causes the amount of light passing through the display to change, creating the image seen on the display. Therefore, polarization is the best choice for this question.
