An LCD display is a flat panel display, or monitor, that uses liquid crystal cells to create an image. LCDs are found in a wide range of devices, including laptops, tablets, smartphones, and televisions.
How do LCDs work? Liquid crystals are molecules that have the ability to change their orientation in response to an electric field. This means that they can be used to control the light passing through them. In an LCD display, each pixel (the smallest element of an image) is made up of three sub-pixels: one red, one green, and one blue. By applying different voltages to these sub-pixels, it is possible to produce a wide range of colors. The pixels are arranged in a grid on the front of the LCD panel; each pixel has two transparent electrodes (one on the top and one on the bottom) that apply the voltage across the liquid crystal layer.
The first commercial LCD displays were developed in the 1970s and were used primarily in electronic calculators. Since then, LCD technology has evolved rapidly; today’s displays are thinner, lighter, and more energy-efficient than ever before. They are also capable of displaying high-resolution images with lifelike color reproduction.
