![]() ![]() This technology is usually only found on low-end to midrange TVs. This allows for a brighter image as a whole. Direct-lit LED displaysĭirect-lit LED displays do away with edge-lighting and instead place a few LEDs throughout the back of the screen, meaning that more light is supplied, and light is more uniform across the display. But the downside is that these displays aren’t as bright as other types of LED displays. That’s why you don’t only see an image around the edges of the screen. The light created by these LEDs is scattered with a light diffuser, creating a more uniform image. Most older LED displays are edge-lit, which basically means that there’s a series of LEDs placed around the edges of the display. For the purposes of this guide, it doesn’t really matter how LEDs work though - just that they produce light.īut there are different types of LED displays - and the different types largely have to do with how many LEDs there are, and where they’re located. LED stands for Light-Emitting Diode, and it basically works by passing a current through a semiconductor material. But what defines an LED display has less to do with how the display filters light, and more to do with the source of that light in the first place. Display types explained: LED displaysīy now you’ve probably caught on to the fact that LED displays aren’t different from LCDs. But recently, manufacturers have instead turned to a different type of backlight - the LED. Traditionally, LCDs have used CCFL backlights, which contain mercury. The backlight supplies the light that is ultimately filtered to create an image. There’s one final component to LCD technology - a backlight. And, each sub-pixel has a red, green, or blue (RGB) color filter, and combining these can effectively create any color. This is done by dividing each pixel into three sub-pixels, which is an individually controlled LCD segment. Of course, you might be wondering how these displays can produce color, and for a long time they didn’t - and still don’t on many LCDs. When you have millions of pixels, that can make for a relatively detailed image. LCDs can let through or block light on a per-pixel basis. A grid of millions of transistors then supplies power to the crystals, causing them to open or close, and ultimately filtering the light that can pass through the polarized layer in a way that creates an image. LCDs basically use a thin crystal solution layer sandwiched between two polarized glass panels. And different display types offer different advantages and disadvantages.Ĭonfused by all the different display names, and what they mean for your devices? Here’s a brief explainer of display technologies, and what makes them great.īy far the most common display type today is the LCD, or Liquid Crystal Display (so yes, the title LCD display is redundant). But those displays can actually be made in a number of different ways. Between the screens on phones, TVs, computers, and even fridges, you probably rely on looking at a screen for many aspects of your life. Screens dominate our lives, and we’re looking at them more and more.
