What is the primary phenomenon responsible for the operation of liquid crystal displays (LCDs) found in electronic screens?
A. Total internal reflection of light rays
B. Polarization and rotation of the plane of polarization of light✓ Correct Answer
C. Interference of thin films due to varying thickness
D. Stimulated emission of coherent radiation
💡 Solution & Explanation
Liquid crystal display technology operates by utilizing the polarization properties of light and the ability of liquid crystal molecules to rotate the plane of polarization when voltage is applied. Total internal reflection is utilized in fiber optics rather than standard LCD panels.
