Samsung, LG… OLED TVs of 2023 will burn your retinas
News JVTech Samsung, LG… OLED TVs of 2023 will burn your retinas
If you are directly or indirectly interested in the small world of high-end 4K TVs, you should already know all about OLED technology. In 2023, Samsung’s QD OLED and LG’s classic OLED will pass a dazzling milestone. We inform you about it.
A reminder of the basics: What is OLED technology in 4K TVs?
Before we explain how the 4K OLED TVs of 2023 will evolve, we need to understand where they started. So here’s a little background on OLED technology in general.
OLED has set itself at a high level to solve the painful problem that exists in absolutely all traditional LED TVs: contrast. Recall that contrast on a TV represents the difference in intensity between the lightest and darkest areas of the image.
This contrast problem is due to a technological limitation: mainstream LED TVs are solid rear light panel. Simply put, this means that builders need to place a large, bright panel that emits white light just below the screen. This light is then filtered to give you a wide range of colors. In LED TVs, since the backlight panel is constantly on, black color often tends to gray, and in general, all colors are somewhat soft, lacking depth.
The advantage of OLED is removing this backlight panel. Each pixel generates its own light (then we’re talking about self-emitting pixels) and adapts directly to the projected image. When black is displayed, the pixel simply turns off. Result: Since blacks are perfect, an OLED display’s contrast is said to be “infinite.”
Nothing flows, the viewing angles are crazy, everything is perfect. All? Not really. In the early days of OLED, techno posed 3 major challenges :
- 1. When a live and static image remains for too long (a bright red life bar, a continuous news channel logo…), it can “burn in” the screen and be etched on the TV for life. Nowadays, manufacturers have put a lot of things in place so that this problem does not arise anymore (automatic cleaning of pixels, detection of risk areas, alternating active pixels, reduction of brightness, etc.). Mission successful : so-called problems burn belongs to the past.
- 2. In the mid-2010s, the production of large-sized OLED panels was quite complicated and quite expensive. The first 4K TVs equipped with this technology cost a fortune and stocks were very limited. Worse, only one LG-owned factory in the world was able to produce OLED TV panels, all other brands were supplied by the Korean giant. In 2022, OLED started to become more popular and Samsung started making its own panels. Well, OLED is reserved for the high end and always costs more than good old LED, mBut the current prices cannot be compared with the prices applied a few years ago.
- 3. Removing the backlight panel is nice, but it’s hard to achieve very high brightness levels without it. To fully enjoy a 4K OLED TV, it is better to be in the dark. While Samsung managed to exceed 2,000 lumens per square meter on its Mini-LED TVs, OLED struggled to reach 1,000 peak brightness.. Placing an OLED TV in a directly lit room was a big challenge…until this year.
Samsung’s 2023 OLED TVs are so bright they’ll dazzle your eyes
In 2023, OLED brightness problems are definitely a thing of the past. The world’s largest high-tech event, CES 2023, is currently underwayLG just announced that its top-of-the-line OLED TVs of the year should achieve 70% brightness. Last year’s LG OLED Evo panels flirted with 1,000 candelas per square meter. Theoretically, therefore, we should reach about 1700 cd/m².
This feat is already insane, but Samsung is going even further. According to the manufacturerThe top of the range 4K QD-OLED TV from Samsung, christened Samsung S95C, should reach 2000 candelas per square meter. Waiting for the level of mini-LED… it’s terrible. With so much light, even if you watch TV in the dark, your eyes will hurt. OLED will soon be flawless…
Now what is QD-OLED? When we talk about self-emitting diodes, we are actually talking about white light. Usually, we put a red/green/blue filter on top of this white light to get all the color shades on the screen.
This is a big difference to what QD-OLEDs offer. Samsung Display’s self-emitting diodes are blue diodes. There is no filter, but the famous “Quantum Dots” (quantum dots) inherent in QLED technology. These Quantum Dots are nano-crystals that react to the passage of light. It is these nano-crystals that take care of the green and red.
After a year of commercialization, QD-OLED technology will pass a major milestone in 2023. The new Samsung S95C will be slimmer, will have remote connection in the famous “One Connect” box, 144 Hz (like a PC gamer screen…) streaming and 2000 nit brightness.
Competition should only be taken care of.
