You probably own one or more devices with an LCD display screen at home and work. This includes your TV, computer monitor, watches, clocks, smartphones, and even calculators. But have you ever wondered about how your LCD screen works, its lifespan, components, and how it holds up to other emerging display technologies today? Knowing all these things about your LCD display lets you appreciate your screen all the more. Caring for your device becomes easier when you’re armed with this knowledge. Without further ado, here are the basic things you need to know about LCD display. How Does LCD Display Screens Work? LCD screens make use of Liquid Crystal Display (LCD) technology. The screen is embedded with liquid crystals, a substance that has properties in between a conventional liquid and a solid crystal. Liquid crystals can flow, but their molecules carry a crystal-like solid orientation.

2. Liquid crystals are responsible for producing an image flashed onto the LCD screen. They don’t emit light, though. Backlights are used to illuminate these crystals. for 8 hours a day, 5 days a week. The backlight's life expectancy is the biggest factor in determining the LCD display lifespan. It's because liquid crystals do not give off light from themselves. The liquid crystals depend on the backlight for illuminating them. Hence, the LCD screen wears off when the backlights dim as it reaches its maximum lifespan. LCD Display Components Several components make up an LCD display screen. We'll explain each one here: 1. Backlight The backlight serves as the illuminator of the entire LCD display device. Without a backlight, the LCD device remains darkened and hard to use. Backlights are installed directly behind the LCD panel to lighten up the display. Simple devices such as pocket calculators don’t use a backlight for their LCD screens. Users rely on natural light to see the numbers displayed on such calculators. However, the majority of modern LCD screens such as televisions, computer monitors, smartphones, aviation screen panels, outdoor signages, and medical monitoring devices use backlights as their internal light source. There are various types of backlights used in LCDs, and here are some of them: a. Light Emitting Diode (LED)

3. This type of backlight is the most popular and widely-used light source for LCDs today. Light-emitting diodes are semiconductors that emit light once electric current flows into it. Particles carrying the electric current are called electrons holes. These combine with electrons in the semiconductor, releasing photons (light particles). Band separations called bandgaps determine the photons’ energy. Furthermore, the photon’s energy dictates which color the LED emits, depending on the emitted light’s wavelength. Various kinds of semiconductors and their corresponding varying bandgaps create different light colors. LED has many sub-categories, including: • Edge-Lit White LED (EL-WLED) – One or more LED rows are placed on the screen’s edge. A special light diffuser is used to scatter the light evenly across the entire display screen. Computer monitors, laptops, notebooks, and even HDTVs are now lit in this way. • White LED (WLED) – The LCD panel’s rear side is lit up with several white- colored LEDs. A diffuser is set in front of the LEDs to help evenly smooth out the light throughout the screen. Some computer monitors and large-screen LCD TVs use this LED technology. • Red-Green-Blue LED (RGB LED) – This technology works like WLED. The difference is that it uses red, green, and blue LED combination lights instead of white lights. Better picture quality and higher color gamut are its advantages over WLED and EL-WLED. 2. Liquid Crystals Liquid crystals are the heart of an LCD display. This unique substance flows like a liquid but retains many characteristics of solid crystals. They have long and cylindrical-shaped molecules that can twist when changes in molecular orientation happen. Different liquid crystal families are used in LCD displays. One requirement of such liquids is to exhibit mutual attraction. Also, the molecules in the liquid crystal need to be anisotropic. This means that the liquid crystal molecules have that average structural order along a molecular axis. Liquid crystals are often sandwiched in between the color filters and the polarizers. They twist and straighten in response to electrical currents applied to
