Abstract:
Polarization is a fundamental property of light that describes the orientation of the electric field vector during wave propagation. The control and manipulation of polarized light play a crucial role in many optical devices, particularly liquid crystal display (LCD) technology. LCDs rely on polarized light, liquid crystal molecular alignment, and electro-optic effects to modulate light intensity and generate images. This paper presents a detailed discussion on the principles of light polarization, different methods of producing polarized light, and the working mechanism of LCDs based on polarization control. The structure, operation, advantages, limitations, and applications of LCD technology are also discussed.
