A Liquid Crystal Display Television, commonly known as LCD TV, uses liquid crystals to produce images on the screen. These crystals are sandwiched between two layers of glass or plastic and are illuminated by a backlight, typically made of LEDs. When an electric current passes through the liquid crystals, they change alignment, allowing varying amounts of light to pass through and create colorful images. LCD TVs are popular for their slim design, energy efficiency, and ability to display sharp images. They are widely used in homes and businesses for entertainment and presentations. With advancements in technology, many LCD TVs now offer features like smart TV capabilities, allowing users to stream content directly from the internet.
