LG OLED TV vs. Conventional TVs: What’s the difference?


In the world of consumer tech, there is a lot of hype around Organic Light Emitting Diode (OLED) display technology, found in high-end models such as the LG Signature OLED TV W.

Touted as the next frontier of entertainment, the LG Signature OLED TV W swept up awards at the recent 2017 Consumer Electronics Show, earning several Best of CES 2017 accolades and securing a total of 45 awards.

But beyond the hype, what are the actual differences between an OLED and a conventional Light Emitting Diode (LED) or Liquid Crystal Display (LCD) TV that is predominantly the technology used for all UHD TV in the market?

Here is a quick breakdown.

Difference 1: Viewing angle


Despite entertainment options available on more screens and devices than ever, the home TV remains the focal point for the whole household’s entertainment needs.

While the joy of watching shows together as a family has a unique appeal, it also poses a unique problem: a fight for the best vantage point on the sofa. Most conventional TV users will find a plunge in picture quality once they move off-centre and do not face the TV directly. That means that in a family of four, at least two members are getting a sub-optimal view of the show. In fact, based on a Japan Ergonomics Society research survey in 2012, 95% of consumers watch TV at a 40-degree angle and more.

Enter LG’s OLED TVs, which maintain consistent picture quality and clarity at any viewing angle. They deliver consistent colors at wider viewing angles, regardless of the angle at which viewers are seated. An internal test conducted by LG found that, when viewed at a 60-degree angle, LG’s OLED TVs deliver images that are 12 times more accurate than that of a conventional TV.

With LG’s OLED technology, it is now possible to share the full cinematic experience with your loved ones.

Difference 2: Perfect black


Black is black, right? Wrong. LG’s OLED TVs can deliver a black that is 200 times darker than the same colour on a conventional LCD/LED TVs.

The difference is in the pixels. LCD/ LED TVs use backlight unit technology, which results in a lack of detail in dark scenes and light leakage. To mitigate this issue, conventional TVs sometimes deploy dimming technology to dim some of the darker LCD blocks on the screen. However, this may make certain visual details hard to discern.

OLED TVs, on the other hand, use self-lighting pixels, meaning each individual pixel can turn on or off in accordance to the images displayed on screen. Since pixels can individually shut off, they can achieve that coveted “perfect black”.

As LG Signature OLED TV W delivers “perfect black”, the colour contrast in dark scenes is vastly superior to that of a conventional TV, allowing you to make out exactly what is happening on screen.

Difference 3: Colour reproduction

In an OLED TV, these aforementioned self-lighting pixels offer a lot more than the perfect black. They also produce an impressive spectrum of colours not found in conventional TVs.

The LCD/LED TV, due to its backlit screen, creates excessive brightness and overly saturated colours that might differ from the original video. These unnatural colours can often come across as jarring.

With an OLED TV’s pixels, screens display the intended, original colours that are both natural and vivid. LG’s OLED TVs’ Wide Colour Gamut (WCG) technology creates realistic, rich colours, and captures a much wider spectrum of colours so you get precise colour adjustments.

The result? A palette of a billion colours — that’s 64 times more colours than a conventional TV delivers.

Difference 4: Refresh rate

The refresh rate of a TV dictates how often it changes each frame on the screen. Low refresh rates can lead to motion blur, which is the illusion of streaking when there is rapid movement on screen. This can be undesirable for some, especially when it comes to sports and action movies. Motion blur can obscure the precise position of athletes or fast moving objects.

OLED TVs have a much higher refresh rate than many LCD/LED TVs. Under LG’s Clear Motion technology, OLED pixels respond immediately to image signals, reproducing clear images up to 1,000 times faster than a than a conventional back-lit TV. This reduces motion blur and allows for more accurate viewing experiences with fast-paced shows.

Gamers, take note: your gaming experience is also about to level up, thanks to the higher frame rates in an OLED TV.

Difference 5: Design


Finally, the true marvel of OLED comes from its ability to unlock the potential of TV design. Conventional TVs have LED lit modules behind layers of panels, so it is challenging to find a truly thin unit. Looking at LG’s lineup of conventional TVs, it would seem that the thinnest an LCD/LED TV can go is at least 4.5mm.

With OLED TVs’ individually lit pixels, TV screens no longer require many layers of panels. Instead, a nearly razor-thin design is possible. The LG Signature OLED TV W is a mind-boggling 2.57mm in thickness — as thin as two $1 coins stacked together. Now, your TV can blend in almost seamlessly on the wall.

It goes to show that OLED technology is not merely a geek’s dream come true, but heralds a true revolution in TV design.

If OLED is a game-changing technology, then LG’s award-winning Signature OLED TV W is the pinnacle of the OLED experience.

With its stunning design, innovative technology and superior performance, it’s easy to see why this ultra-high-end TV is a critic’s darling. Designed to deliver a purely cinematic experience; it enhances everything good about TV, while stripping away everything that is not.
