But first, let’s understand what LCD and LED TVs actually are. LCD stands for Liquid Crystal Display and is a panel technology that uses liquid crystals to create images. On the other hand, LED stands for Light Emitting Diode, which refers to the type of backlighting used in the TV. Now that we have clarified the basic definitions, let’s dive into the differences between these two types of TVs.
Definition of LCD and LED TV
To understand the differences between LCD and LED TVs, it’s essential to have a clear definition of each technology.
LCD, or Liquid Crystal Display, is a panel technology used in televisions. It consists of a layer of liquid crystals sandwiched between two layers of glass. These liquid crystals can be manipulated to control the amount and intensity of light passing through them, which allows for the creation of images on the screen.
On the other hand, LED, or Light Emitting Diode, refers to the type of backlighting used in a television. In an LED TV, the display panel itself is made up of liquid crystals, just like an LCD TV. The difference lies in the type of backlighting used. Instead of traditional CCFL (Cold Cathode Fluorescent Lamp) backlighting, LED TVs use an array or grid of small light-emitting diodes as the primary source of illumination.
This distinction in backlight technology leads to some significant differences between LCD and LED TVs. While both types use liquid crystal display panels, the primary difference lies in the way the panels are illuminated.
Traditional LCD TVs rely on CCFL tubes placed behind the panel to light up the screen. These tubes emit a consistent level of backlighting across the screen, but they are limited in their ability to control individual areas of brightness. As a result, LCD TVs often suffer from issues such as lower contrast ratios, limited black levels, and narrower color gamuts.
LED TVs, on the other hand, use an array of light-emitting diodes as the backlight source. These LEDs are capable of independent control, allowing for more precise lighting control and better dynamic range. This technology enables LED TVs to produce deeper blacks, higher contrast ratios, and a wider color gamut compared to traditional LCD TVs.
It’s important to note that LED TVs are essentially a type of LCD TV with a different backlighting method. The term “LED TV” is used to distinguish this newer backlighting technology from the older CCFL tube backlighting used in traditional LCD TVs. So, when we refer to LED TVs, we are still talking about an LCD panel with LED backlighting.
