An Introduction to LCDs and How They Work

Advantages of LCDs

LCD has become the world's leading display technology. When compared to older display technologies, such as cathode-ray rube (CRT), it supports the use of smaller and thinner displays. CRT displays are large and bulky. LCDs, on the other hand, are typically small and thin. This is why so many smartphones use an LCD.

Devices that use an LCD typically consume less power than their counterparts with a different type of display. Statistics show that the average LCD consumes about 10% to 20% less power than CRT of the same size. With lower power consumption, businesses and consumers can save money by using an LCD.

LCDs don't suffer from screen burn-in. Screen burn-in is a phenomenon in which a display's image becomes static and permanent. Displays are designed to change their images. After all, that's what gives images motion. In some displays, either some or all of an image may become permanent. Known as screen burn-in, it was particularly common among CRT displays.

Screen burn-in occurs when a display contains phosphor compounds. LCDs don't have phosphor compounds, so this isn't a concern for them. LCDs are fully protected from screen burn-in.

Another advantage of LCDs is their ability to support high resolution. Resolution refers to the number of pixels within a display. LCDs can be designed with a high resolution, and with more pixels, they produce clearer and better-detailed images.
