What Is an LED-Backlit LCD?
Have you heard of LED-backlit LCDs? It's become the leading display technology for high-definition TVs as well as smartphone and other mobile electronic devices. Many consumers are skeptical of buying an LED-backlit LCD, however, because they are unfamiliar with the technology. If this sounds familiar, you should read the following information about LED-backlit LCDs and how they work.

Overview of LED-Backlit LCDs
LED-backlit LCDs are essentially liquid crystal displays (LCDs) with a light-emitting diode (LED) backlight. LCD technology has been around for decades. Even today, though, all LCDs require a backlight to illuminate their liquid crystals and produce visual images. Without a backlight, an LCD wouldn't be able to produce a clear, visible image. And while there are several different types of backlights available, LED is the most common. LCDs that feature an LED backlight are known as LED-backlit LCDs.
LED Arrangement
In a typical LED-backlit LCD, the individual LED bulbs are arranged in one of two ways. The first option is to place the LED bulbs in a perimeter around the edge of the display in a diffusion pattern. This evenly distributes the light to provide even illumination throughout the device's liquid crystals. The second option is to arrange the LED bulbs behind the screen at evenly spaced distances. This arrangement also provides an even distribution of light, thereby offering bright, clear images.
