Market researchers predict: More OLEDs in all devices

According to market researchers from Omnia, organic displays will see annual growth of 43 percent over the next few years. OLEDs will be found in more and more smartphones, but the high-contrast displays should be found more and more in IT devices such as tablets and notebooks in the future. Even if you can already find OLEDs in tablets from Samsung and in notebooks from HP, Lenovo or Asus, a lot depends on Apple here.

If you look at the OLED market by area, TVs dominate, but given the display areas in the individual devices, the proportion of smartphones is huge.

With Apple’s entry into OLED tablets, the market will gain significant momentum, predicts Ross Young from the market research company DSCC. He expects the first iPads with organic displays in the coming year. An 11.1-inch iPad Pro and one with a 12.9-inch diagonal are expected, both of which will be offered in parallel with LCD variants with mini-LEDs (12.9″). Since LG Display wants to start mass production of such OLED sizes in a new factory in Paju (South Korea) from the fourth quarter of 2023, LG is likely to be one of the panel suppliers alongside Samsung.

It is still unclear whether Apple will be launching a MacBook Air with an organic screen as early as next year. From 2026, on the other hand, DSCC expects the first MacBooks Pros with OLED panels. They are said to come from Samsung’s new OLED factory of the 8.7 generation in Tangjeong, LG wants to deliver OLED panels from Paju from 2027. Whether Apple will even present a foldable notebook with an organic screen in 2026 also depends on the availability and reliability of flexible OLEDs.

Although LCDS still dominate in the IT sector, this could change in the foreseeable future, at least in the case of notebooks.

In order to achieve the necessary luminance, organic screens for smartphones, IT devices and TVs are to be equipped with a so-called tandem stack from 2024. This is a double organic luminescent layer inside the panel, which provides more light output with the same energy supply.

Phosphorescence for more blue

Great hopes are also pinned on the new blue OLED phosphor, which emits light by phosphorescence and thus works much more efficiently. The US company UDC has been working on phosphorescent organic phosphors for a long time and has been promising for some time that they are on the verge of a breakthrough. However, the date for mass production has been pushed back several times, UDC currently speaks of 2024, DSCC accordingly assumes mid-2024. Others have already bitten their teeth on such phosphorescent phosphors, including Cynora with the phosphor called TADF, which also wanted to use the three times more efficient light generation by phosphorescence. Samsung has since taken over the patents and closed the shop.

LG has already demonstrated the use of heavy hydrogen for a better energy balance: according to DSCC, deuterium increases efficiency by up to 30 percent. We described how deuterium works in the OLED in the article Heavy water against burn-in on the OLED. The lens raster MLA (Micro Lense Array) used by LGD also ensures higher luminance levels. In its QD-OLEDs, Samsung relies on blue-glowing organic layers and uses quantum dots to convert their light into red and green light. That’s why much of the QD-OLEDs depends on efficient blue phosphors, as promised by UDC.
