LG Samsung OLED Sledging Had To Happen As Fight Gets Nasty

The sledging had to come in the battle between Samsung and LG in the OLED TV market, and it’s LG who has come out swinging.

Dragging up an old argument, LG management from the Company’s Display division that have just dropped a billion dollars in losses, has slammed Samsung’s QD OLED screens for their susceptibility to [yes, you guessed it] screen burn.

This is the Company who for years defended the issue of burnout on their own OLED TVs.

Most cases of burn-in in televisions is a result of static images or on-screen elements displaying on the screen uninterrupted for many hours or days at a time – with brightness typically at peak levels. So, it is possible to create image retention in almost any display if one really tries hard enough.

On one occasion, LG management were doing a media launch for a new range of OLED TVs, then stopped for lunch only to discover that when they returned the paused TVs had burnt images into the screen.

At a hastily arranged press briefing last week, LG Electronics management revealed independent test results that showed that the South Korean Company’s C2 WOLED TVs from 2022 are less susceptible to image burn in.

At the event, screen shots taken from technology review website Rtings showed images from LG Electronics’ 2022 G2 and C2 OLED TVs that appeared to be completely free of any permanent image retention.

Then along came the kick in the guts, with LG management then claiming that two TVs that use Samsung Display’s QD OLED technology, Samsung’s S95B and Sony’s A95K, both showed signs of image burn-in.

UK reviewer John Archer claims it all boils down to the fact that since LG Display’s OLED panels use a white subpixel in the creation of their pictures (something Samsung has criticised them for over the years, on the grounds that they don’t deliver a pure RGB picture), the RGB subpixels in LG’s WOLED panels are subject to much less stress over time than QD OLED’s RGB subpixels are.

And since it’s the ‘fatiguing’ of specific areas of RGB pixels by prolonged exposure to static image elements that causes screen burn, it therefore follows that a pure RGB solution is going to be more susceptible to screen burn than a WOLED one.

As soon as the sledging of Samsung and Sony TVs was over, LG Display management suddenly disappeared from the press conference before journalists could question them.

Samsung claim that their second-generation of QD OLED TVs are using improved heat management and a new OLED ‘HyperEfficient Electroluminescence material’ to reduce their susceptibility to screen burn.

Samsung also has a multiple product range of premium LCD TVs in their line-up.

LG Display management also failed to reveal that the trials Rtings subjected the test TVs to for its burn-in tests isn’t remotely representative of normal TV usage.

They also failed to mention that all OLED TVs carry specific countermeasures designed to minimise susceptibility to screen burn.
