Purification and upgrading capabilities of firms like Isowater enable D₂O recycling while supporting efforts to address the growing global shortage of high purity D₂O

Advanced capabilities to purify, refine and upgrade deuterium oxide (D₂O, or “heavy water”) are expanding opportunities for OLED display manufacturers to sell D₂O that has been downgraded and contaminated during fabrication.

These capabilities also support the efforts of companies like Isowater Corporation, a world-leading supplier and recycler of deuterium oxide, to meet the growing demand for high purity D₂O at a time of dwindling global supplies.

This is the fifth article in our OLED display backplane series. In the previous article, we examined oxide TFTs (IGZO), the transparent metal-oxide semiconductor that brought ultra-low leakage and large-area uniformity to OLED TVs and monitors. Here, we look at LTPO - the hybrid backplane that puts LTPS and oxide transistors on the same panel to enable variable refresh rates from about 1Hz to 120Hz.

Two materials, one backplane

Despite the name, LTPO - low-temperature polycrystalline oxide - is not a new semiconductor at all. It is a hybrid backplane that places both LTPS and oxide (IGZO) transistors on the same panel and uses each one where it is best. The idea was originally developed by Apple, which filed its foundational patents around 2014, and it has since become the defining backplane of the premium mobile display.

OLED microdisplay producer Rayvision Technology operates an 8-inch silicon-OLED fab in Guangxi that entered production in  2023, and is building a $415 million 12-inch fab in Changsha. We have now added the company's complete microdisplay catalog - nine panels, from 0.39" to 0.96" - to our OLED Marketplace.

The new panels include a 0.39" 1024x768, a 0.60" 800x600, a 0.61" 1280x1024, a 0.71" 1920x1080, and the largest of the line, a 0.96" 1400x1050.

In July, we reported that TCL CSOT has began to commercially produce consumer inkjet printed OLED panels, for laptops and monitors. The company has now announced that its inkjet printing process has reached the point of "stable mass production".

TCL CSOT already announced it is starting mass production at its 5.5-Gen inkjet printed OLED line towards the end of 2024, but these were panels that target the medical market, that were produced at a very low volume. The company is now ramping up production for consumer products, at higher levels. TCL's first panels are produced at the company's 5.5-Gen pilot line. The company's T8 large-scale 8.6-Gen line is not ready for production yet.

OLED producer Qingyue Technology has seen its share price decline quite a bit as of late, and now as the share price traded below 1 yuan for 20 consecutive trading days, the stock has been delisted and is no longer trading. At its high, on January 2024, the company traded at 24.88 yuan, that is a drop of over 97%..

Earlier this month, Qingyue reported  its financial results for the first half of 2026, with $41 million  in revenues (down 16% from 2025) and a net loss of $34 million. Qingyue mainly produces and sells three display types: ePaper (E Ink) modules, PMOLED displays and OLED microdisplays.  It says that low demand for its ePaper displays is the main reason of the reduced results.

UBI Research estimates that medium and large OLED revenues will grow from $10 billion in 2026 to $15.15 billion in 2030, a CAGR of 11%.

Most of the growth will come from two applications: monitors and automotive displays. OLED monitors will continue to grow quickly, and will triple in revenue from $1.52 billion in 2026 to $4.7 billion in 2030 (32.5% CAGR).
