LCD TVs Won't See Any Further Development (tomsguide.com) 70

Posted by BeauHD from the it's-official dept.
According to an industry insider, LCD TVs won't see any further development because all new R&D money is being spent on self-emissive displays like MicroLED and OLED, as well as on backlight technology like Mini-LED. Tom's Guide reports: According to Bob Raikes from Display Daily, it's all about OLED development. "I asked EMD (which is the US name of Merck KGaA and is by far the dominant supplier of LC materials), what they were doing to push LC materials for displays onto the next stage ... They are developing LCs for privacy windows and antennas, but they told us that 'there is no pull from clients' for significant development in LC materials," Raikes wrote in a recent article. "That shouldn't have been a surprise to me -- I have been talking about the switch to OLED and other emissive displays for the premium end (and later the mainstream) of the display market for a lot of years. Still, after decades of reporting on LC developments, it took a moment to sink in!"

As for what, specifically, manufacturers are working on, it's the production of QD-OLED panels for use in the high-end Samsung and Sony TVs like the Samsung S95C OLED and Sony A95K OLED as well as the development of PHOLED panels that use a blue phosphorescent material that has a longer shelf life and can go brighter than the traditional organic material in OLED panels. [...] Sadly, LCD TVs' days are coming to a close, but OLED TVs are still going strong.

      What would you have bought, if LCD and OLED TVs were priced the same, or OLED TVs were actually cheaper than their LCD counterparts?

      I suspect that will be the case in the near future, and that is what they mean by lack of "pull". Very few people are interested in paying more money to get an inferior/outdated technology.

        That depends on what other disadvantages a cheap OLED TV might have, such as more burn-in or more surveillance of viewing habits.

      Those displays you referenced exist, so no new "development" required for them to continue to exist and be manufactured moving forward.

      That's my take, that we are pretty much as far as we can reasonably advance LCD tech. You can have supremely dense and supremely large LCD panels at diet cheap prices. What more do we need to develop at this point?

      Meanwhile, uLED and OLED need development. Very good in some respects, but expensive and struggle with burn in.

          It means that they're investing in improving the backlight technology, but not the LCD panels themselves. You'll get better full array local dimming, but not better viewing angles, contrast ratios, pixel response times, etc. The current tradeoffs that we have between VA/IPS/TN will probably be with us until LCD panels are fully replaced by self-emissive displays.

        No they are not. MicroLED and QDs are both self-emissive separate display technologies. You've been confused by Samsung's abusive marketing (their QDTVs do not use the development known as Quantum Dot displays, they just use it to make a better filter for their LCD).

      Of course they want to flog OLED. OLED is the poster child for the industry because it degrades and gets us back to a technology subject to burn-in. TVs are at the point where you can't get better resolution and be able to see the difference and this has the industry scared. Oh My God, what if we go back to the bad ole days of the 70's where people bought a TV and kept it for fifteen years? They might only be able to sell one TV to a person in their lifetime!

      It's not good enough that they have people disposing their phones every three years - the TVs are next on the chopping block for devices that you have to pitch. I'll never buy an OLED device, and neither should you. The whole technology is offensive.

        Yes, that's exactly why the majority of R&D invested in OLEDs has been to prevent this situation over the past 2 decades.

        • Yes, that's exactly why the majority of R&D invested in OLEDs has been to prevent this situation over the past 2 decades.

          The majority of research in the last two decades has been how to mask the problem, and then offering misnamed bandaids like "Pixel Refresh" which actually make the problem worse. Pixel Refresh doesn't actually refresh the pixels. It raises the voltage for individual pixels that are dimming. Customers believe it's doing some magic to undo the damage which caused the dimming, and really those pixels are just getting shocked into brightening at the expense of even more rapid wear.

          Great work on that research

      • I think you're partially correct, the display business does seem to be very trend-influenced. Remember when we all switched to wide screen, because that was better for some reason? And now we're switching back, because that's better now?

        It's not about degredation, it's about distinguishing your product. Displays are practically commodity items, so anything which sets yours apart is valuable. And once a feature catches on everyone else needs to copy it, otherwise they'll end up looking old and obsolete.

        OLED panels may degrade the fastest, but like other display tech (LCD, plasma), it's much, much more likely something else will fail (psu, board, backlight) before the panel reaches its half-life.

        OLED offers a huge leap in image quality, and only the largest ones are expensive ( $3k+). well worth the price of admission for those with the sense to appreciate it.
