LED Television Technology


In order for companies to stay competitive they need to give consumers something new and interesting. And this is exactly what major television manufacturers are doing. One of the most recent developments in TV technology is LED, and this article will expound on this one-of-a-kind technology to help readers understand what it is and why it is selling like pancakes today.

A Quick History on Led Television Technology

Originally designed for use in indicator lamps, the LED technology has come a long way. It was Samsung that first used LED (light-emitting diodes) in TV technology. Prior to the introduction of LED, backlight screens were mainly CCFL (Cold Cathode Fluorescent Lamp), but TV manufacturers have come to realize just how much better LED technology is for backlighting, compared to CCFL, considering the many advantages it has over the other. This is why today, more and more LCD TVs make use of LED technology.

How the Led Television Technology Works

To understand LED technology, you need to know how the diodes produce light. Diodes can be found in circuits, and are basically classified as an electrical device. When a diode’s atom is energized by means of an electric current, it releases energy in the form of visible light. The electric charge carriers flow from the electrodes and then release light. The light can change colors, and many LED lights can be grouped in different patterns in order to produce many different kinds of light.

Types of Led Television Technology

Led television technology comes in three types, which are: Blue LEDs, White LEDs, and Organic LEDs. Blue LEDs make use mostly of gallium nitride semiconductors, which can also produce white light when combined with other LEDs. White LEDs are created to eliminate the need for traditional LED lights to mix, and only require a zinc selenide substrate to produce color. Organic LEDs or OLED utilizes carbon in the diodes, and are known to produce the finest color quality among all other types of technologies.

Types LED Technology Lighting

LED technology offers either edge lighting or full-array backlighting to current LCD TVs. With edge lighting, there are LED backlights along the screen’s edges, which makes the TV really slim. When the light disperses, it produces uniform color on the screen. Full-array backlighting, on the other hand, gives the entire screen surface a series of LED backlights. This allows each LED to be turned on and off in the screen for better control. Full-array has thicker panels than edge lighting.

Televisions built with LED technology are still pricey compared to other existing LCD TVs. However, for individuals who are looking for better picture quality, improved functionality, and slimmer TV models, Led television technology seems to be the most popular choice. If you are thinking of getting one, it is necessary to decide first on what type of LED technology to use, along with the type of lighting. Consider the pros and cons of each before making a purchase.
