Final answer:
The LCD monitor utilizes a liquid a) crystal display mechanism where polarization of light can be controlled to create images, with contrast adjustments achieved by applying varying voltage levels to the liquid crystals.
Step-by-step explanation:
The LCD monitor uses a liquid crystal display to produce images on the screen. Liquid crystal displays operate on the principle of polarization, in which the molecules of the liquid crystal can rotate the polarization of light passing through them by 90°. Each pixel consists of three cells with filters for the colors red, blue, and green. The polarization effect can be controlled by applying voltage to the liquid crystals, thus changing the light that passes through the filters and allowing for the manipulation of image contrast and color on the screen.
