After the era of CRT TVs ended, most people considered the new type as generally the flat-screen<\/a> TV. However, this flat TV comes in different types, each with unique technology behind the picture creation process. The two primary types are plasma and LED, and each has a unique operating mechanism. We have done a plasma TV vs. LED comparison below to help you pick the best TV that fits your needs. Let’s get right into it!<\/p>\n\n\n

How TVs Work<\/h2>\n\n\n

The three TV types operate in the following way.<\/p>\n\n\n

PLASMA<\/h3>\n\n\n

Also known as emissive displays, plasma TVs have tiny color pixels sandwiched between two transparent glass panels. Each pixel contains three gas cells for the primary colors red, green, and blue.<\/p>\n\n\n\n

A tiny grid of electrodes applies current to the individual plasma cells, causing the gas inside (a neon-xenon mix) to ionize. The ionized gas or plasma<\/a> emits UV at a high frequency, which activates the cell’s phosphors to glow and produce the respective color.<\/p>\n\n\n\n

This design does not require a backlight because each cell emits light. Also, the light output is consistent across the screen, giving a wider viewing angle (vertical and horizontal). However, the phosphor coating can cause screen burn-in, like in CRTs<\/a>.<\/p>\n\n\n

LCD<\/h3>\n\n\n

The display section comprises a liquid crystal solution sandwiched between two polarizing transparent panels. Unlike plasmas, LCDs do not emit light. They rely on a backlight to shine through the liquid crystals, making them transmissive displays.<\/p>\n\n\n\n

Glass etching on the inner surface of the screen’s front layer in a grid pattern forms a template for the liquid crystal layer. These liquid crystals are rod-shaped, and an electric current causes them to twist.<\/p>\n\n\n\n

A diffusion layer behind the liquid crystal display panel scatters and redirects the light to create evenly-lit images. Therefore, each crystal acts as a shutter or filter, allowing or blocking light. Allowing and blocking light creates transparent and dark crystals that form the image.<\/p>\n\n\n\n

There are two LCD variations. <\/p>\n\n\n

Active Matrix LCD<\/h4>\n\n\n

These LCDs use thin-film transistors<\/a> arranged as a matrix on a glass substrate. The tiny transistors and capacitors control voltage switching on each pixel and enable rapid on\/off switching.<\/p>\n\n\n

Passive Matrix LCD<\/h4>\n\n\n

Passive matrix LCDs create images using horizontal and vertical Indium Tin Oxide<\/a> conductors. The intersection between two conductors controls each pixel.<\/p>\n\n\n

LED<\/h3>\n\n\n

LED TVs are essentially LED-backlit LCDs. Traditional LCD TVs have a CCFL (Cold-Cathode Fluorescent Lamp<\/a>) backlight but LED displays have LED backlights.<\/p>\n\n\n\n

LED-backlit LCD TVs have several advantages over the fluorescent backlit type. LEDs are easier to control, resulting in more accurate colors and better contrast. Also, they are more energy efficient.<\/p>\n\n\n\n

Plasma TV vs. LED: The Main Differences<\/h2>\n\n\n

LED and LCD panels have many similarities but differ from plasma TVs in several ways. Here is a comparison between LED and plasma panels.<\/p>\n\n\n
