LG rips smart TV in half to show the advantages of OLED

LG showed, in an exclusive workshop, its main TV options with OLED screen to highlight the image quality they can reproduce

THE LG held, this Tuesday (19th), at its headquarters in So Paulo, the LabTech OLED. The main objective of the workshop was to show the benefits and advantages of technology OLED on the panels of the company's smart TVs in relation to the competition.

During the presentation, the LG used one of the main televisions in its current line, OLED 55 B8, 55 inches, as an experimental object. Amid group dynamics, invited journalists were able to learn in more detail what technology OLED, how it differs from the others and why its images offer greater contrast and colors.

LG tore an OLED screen to show how thin, light and malevel it is. Yes, your TV screen is just that sheet, with no additional layers. In other technologies such as LCD, LED and Quned Spot TVs or QLEDs, the thickness needs to be a little bit bigger, because the pixels need an additional light panel to illuminate them. OLED does not need this, because each point of the image already has its own color and lighting. You can see this difference in the final stretch of the video. From left to right, there is an LED screen with full backlight (the entire screen needs to be lit, creating light spots in the image), a screen with Nano Cell technology and Full Array LED lighting (the TV can illuminate specific areas of the image, reducing stains) and the OLED display (without stains, as it does not need backlighting).

The demonstration also considered some of the main features of the TV, with emphasis on the use of artificial intelligence technology. The processor LG OLED 55 B8 uses a combination of functions to analyze the environment of your room and locates the source of the image and sound signal, optimizing these channels according to the content that is playing on television.

How have TV screens evolved over the years?

Before the event begins, the executive Pedro Valery, responsible for the television area of LG in Brazil, stated in a note:

"We think it is incredibly important to take action like this to demonstrate the real functioning of televisions, their differences in technology and image and sound quality, and how this results in totally different experiences for the consumer."

Considering his own statement, the executive started the presentation showing the evolution of screen technologies from the 1970s to the present day.

Tracing a panorama that comes from the 70s with the screens CRT, the famous "Tube TV?: For three decades, this type of panel was the standard for televisions, with only minor developments. The panorama began to change at the turn of the millennium, with the arrival of TV of plasma.

Over the past 10 years, the evolution of screens has grown at a frenetic paceOver the past 10 years, the evolution of screens has grown at a frenetic pace

From there, the evolution of the TV happened at a steady pace, with the arrival of LCD and CCFL in 2005 and the first TVs of LED, released ten years ago.

The screens LED were an expressive evolution in relation to LCD. Still, it has some limitations, such as the impossibility of reproducing the black color in its entirety. Because of the back lighting, the maximum black that the LED can reproduce a shade of gray.

Quantum dots tried to solve this problem and succeeded, but to some extent. When inserting a layer between the backlight and the liquid crystal layer of the screen, the effect of backlighting smaller, allowing a better display of colors. See what the layers of a TV which uses quantum dots in the image below and understand more about how the technologies mentioned so far compare.

The next step in evolution came through the panel LG NanoCell, which brings nanoparticles already applied to an integrated film. It uses a similar premise of quantum dots, but it has two main differences:

The first is the diameter of the crystals, which is smaller than in quantum dot technology. While quantum crystals measure 2 to 5mm, nanoparticles measure 1mm. The second is the way it organizes lighting.

In previous technologies, lighting is done by vertical strips. This means that if there is a small luminous object on a dark screen, the entire strip will be illuminated. J o LG Nanocell makes this lighting by zones, illuminating your display more precisely.

How does OLED technology work?

The technology OLED get rid of backlight totally, since the pixels themselves are capable of producing their illumination. In addition, the problem of light leakage ceases to exist. We can say that only OLED screens are capable of reproducing the black color in its entirety, instead of a shade of gray.

With this, it becomes possible to create a malevelable panel, facilitating the creation of devices with flexible, foldable or scrollable displays, as already happens in LG SIGNATURE OLED TV R, the world's first 'scrollable' TV.

To better illustrate how screens OLED are different from those shown so far, the executive Pedro Valery showed an LED TV, a Nanocell and the display OLED, from left to right.

Currently, the premium line of LG focused on TV production with screens OLED in conjunction with IoT and artificial intelligence. The use of both technologies allows to execute voice commands to control the television, at the same time that the television itself optimizes its settings according to the analysis of the environment and what it is doing.

What are LG's OLED models available today?

At the end of the presentation, the LG showed the main televisions with screen OLED available on the market. Learn more about each one below.

LG OLED E9

Equipped with processor a9 Gen II, a LG OLED E9 automatically optimizes images and sounds according to what you are watching or playing on television. In addition, it is also capable of converting sounds from standard 2.0 to the surround sound 5.1, as if it were a upscaling.

It is compatible with all major virtual assistant models in the Google, Apple and Amazon. Even playing becomes easier, since the famous input lag (delay between the command you made on the control and the one displayed on the screen) less than 1ms.

THE LG OLED E9 is available in a single 65 ? model per R $ 18,999.05 at the Official Store Showmetech at Magazine Luiza.

LG OLED C9

Also equipped with the processor a9 Gen II, a LG OLED C9 also capable of all the functionalities related to artificial intelligence from LG OLED E9. One of the differences between the models is the sound system, inferior to the C9.

In addition, this model is sold in several sizes, being able to choose the ideal one for both your room and your bank account. Check out the prices and sizes available for this model:

  • 55 ? – R $ 6,459.91 at the Official Store Showmetech at Magazine Luiza.
  • 65 ? – R $ 9,499.05 at the Official Store Showmetech at Magazine Luiza.
  • 77 ? – R $ 37,999.05 at the Official Store Showmetech at Magazine Luiza.

LG OLED B9

The third model with screen OLED O LG OLED B9. More accessible than the other models, it comes equipped with the previous generation of the LG processor, the a7 Gen II. Still, it is important to remember that TV still has all the functions of artificial intelligence that its more powerful brothers.

It is also compatible with the main virtual assistants in the market, being behind only the audio quality, which is equal to that of the C9. O LG OLED B9 is available in two different sizes, which can be checked below:

Will OLED be the future of TV screens?

Too early to hit the hammer and say that the standard in the coming years will be that of panels OLED. On the other hand, the flexibility it gives and the clear improvement in the display of colors and contrasts indicate that this may be a near future.

This will depend on other manufacturers and the technologies that may be being developed out of the public eye.
