Introduction

What is an LED TV? And what is a backlight in an LED TV? These are two of the most common questions our customers ask us. In this article, we'll explain how a backlight works and how it helps to improve your viewing experience. We'll also discuss some of the benefits that come with owning an LED TV with a backlight.

 

What is LED TV?

LED TVs are a type of flat panel display that uses LED backlighting instead of CCFLs (cold cathode fluorescent lamps).

LED technology allows for a thinner television and better color reproduction. LEDs have a longer lifespan than other types of backlights, which means you'll get more years out of your TV before needing to replace it. The biggest difference between LED TVs and other types of flat panel displays is that they are more energy efficient. This can save you money on your electric bill over time.

 

What is a backlight in an LED TV?

Backlight is the light that allows an LCD screen to create an image. In older TVs, this was achieved by a fluorescent light (CCFL) behind the screen. In newer LED TVs, LEDs are used instead of CCFLs for backlighting.

In fact, backlighting is one of the most important features to consider when shopping for a new TV. Backlighting makes it possible for you to see what's on your screen clearly and precisely.

How does LED TV work?

A backlight, which is partially composed of two layers of polarizing material with a liquid crystal solution between them, is used to illuminate the image on an LED TV. When an electric current passes through the liquid solution, it causes the crystals to align so that light is transmitted. Ultimately this is how your image appears onscreen: This technology can be likened to a window shutter, which allows light to pass through or be blocked out by closing or opening it.

Edge Lit, Full Array, and Direct Lit are three main configurations of LED backlights, and your TV's lighting configuration has a direct bearing on what you see on the screen.

  • Edge-Lit TVs, as you might have guessed, employ lights around the outside of the screen.
  • Full Array TVs have various zones throughout the display.
  • Direct-Lit TVs, like Full Array TVs, have LEDs put all over the back of the television (but fewer of them).

Benefits of an LED TV with a Backlight

  • Long lifespan and environmentally friendly: Since LED TVs use LEDs as their backlighting source, they have a much longer lifespan than traditional LCD TVs. This means that you won't have to worry about replacing your TV for decades!
  • Excellent Brightness Uniformity: Simply said, the underlying structure and positioning of the backlighting allow it to spread light more evenly throughout the screen, resulting in high-definition visibility. This means that no matter where you sit in relation to the screen (or even if you're off-axis), any dark spots won't be visible at all--and neither will bright spots if they're too bright for your eyesight.
  • Flexible adjustments of luminous frequency: The LED backlight technology is significantly more advanced than the conventional CCFL bulbs in that it entirely eliminates the light flickering across the screen. An adjustable luminous frequency ensures better picture quality by making sure every pixel displays the correct colors according to its intended purpose (which may vary from scene to scene). This also helps reduce eye fatigue by preventing overexposure during long viewing sessions without sacrificing brightness levels during brighter scenes when more light would otherwise be needed.
  • Utilizes low voltage power supply: Since LEDs require less power than traditional lamps or fluorescent bulbs used in older TVs, this makes them ideal candidates for powering small electronic devices such as computers or mobile phones.
  • Easy control and display color characteristics using a variety of hues including blue, red, and green.

Experience the power of TCL’s state-of-the-art technology with its MiniLED TVs. With more than 96,000 tiny intelligent pixels inside each screen, you can experience a stunning picture that puts you at the center of the action.

 

How to choose the right LED TV with a backlight

When shopping for an LED TV with a backlight, it's important to consider the size of your TV and how you plan to use it.

You should also look at how well the contrast ratio works since that will affect how good your image is when watching movies or playing games in dim lighting.

If you want to watch sports in high definition, look for TVs with a high resolution and low input lag (or no input lag). These features ensure that details are as accurate as possible and allow players onscreen to move smoothly without any noticeable delay between their movements and what appears onscreen.

Price is another factor to consider when buying an LED TV with backlight technology; not all brands offer equal value for money across their product range so make sure that whatever budget range suits yours does not sacrifice quality either technically or aesthetically!
