When it comes to choosing a new smartphone, one of the first things you'll notice is the display. In recent years, there have been two main types of screens on phones: LCD and OLED. But what's the difference? Here's a quick overview of each type of screen so you can make an informed decision when buying your next phone.
        LCD screens have been around for much longer than OLED screens. They were first used in calculators and digital watches in the 1970s before making their way into laptops, TVs, and eventually smartphones in the early 2000s. LCD stands for liquid crystal display. As the name suggests, LCD screens use tiny crystals that align themselves in order to create images. 

        One advantage of LCD screens is that they are usually less expensive to produce than OLED screens. They also tend to be brighter, so they're easier to see in direct sunlight. On the downside, LCD screens can suffer from something called "ghosting." This is when fast-moving images leave behind a trail of light, which can be distracting. Another downside is that LCD screens use more power than OLED screens, so your battery will drain more quickly if you're using an LCD screen. 
        OLED stands for organic light-emitting diode. Unlike LCD screens, which use crystals, OLED screens use organic materials that emit light when electricity is applied to them. This means that each pixel on an OLED screen is self-illuminating and can be turned on or off independently. That leads to some major advantages. 
        For one thing, OLED screens have much higher contrast ratios than LCD screens because they can produce true black colors. They also generally have better viewing angles and faster refresh rates. And since each pixel on an OLED screen is self-illuminating, they don't require a backlight like LCD screens do. That leads to better power efficiency, which means your battery will last longer if you're using an OLED screen. 
        So which type of screen should you choose? It really depends on your needs and preferences. If you want a cheaper phone with a bright screen that's easy to see in direct sunlight, then an LCD screen is probably a good choice for you. But if you want a phone with a top-notch display that uses less power, then an OLED screen might be worth the extra cost.
