Liquid crystals do not emit direct light, instead of using a backlight or signal to produce images in color or monochrome. LCDs are available to display conflicting images (as in the case of a typical computer objective) or edited images with low-resolution content, which may be displayed or hidden. For example, pre-set words, digits, and displays of seven components, such as a digital clock, are all good examples of display devices. They use the same basic technology, except that the irresistible images are made with a matrix of small pixels, while other displays have larger features. LCDs may be (positive) or closed (negative), depending on the configuration of the polarizer. For example, a characteristic LCD with background light will have black backlight color, while a negative LCD character will have a dark b...

How Optical fibers works? And How it helps the internet?

Today, In this blog we will know about one of the most important things which help the internet to work properly . This important is known as Optical Fiber Cables. What are fiber optic cables? A fiber optic cable is a network cable consisting of fiberglass cables inside a closed fence of insulator . They are designed for long-distance, high-performance networks, and telecommunications. Compared to cables, fiber optic cables offer higher bandwidth and transmit data over long distances . Fiber optic cables support most of the world's internet, cable television, and telephone systems . Optical-fiber cable is an assembly similar to an electrical cable but contains one or more optical fibers used to carry light . The fiber components are usually enclosed in plastic pairs and are contained in an environmentally friendly protection tube where a cable is used . Different types of cable are used for different applications, for example, long-distance telecommunications, or to provide...
