OLED-Info: the OLED experts

Researchers from the Kaunas University of Technology, the V. Lashkaryov Institute of Semiconductor Physics NAS of Ukraine, and Yuan Ze University, have shown that the performance of the TADF-based OLEDs can be significantly improved by heating, while extremely dependent on the applied biases. These findings are of interest, as normally high temperatures deteriorate the performance of light-emitting diodes, leading to excessive leakage currents, material degradation, and device failure. 

The researchers have achieved a 5 to 6 times improvement in OLED electroluminescence when operating near the turn-on voltage and heating to 50 °C, but also report that the enhancement decreases at higher applied biases. At the same time, current characteristics reveal normal and abnormal regions, where currents increase and decrease with temperature, respectively. 

TCL CSOT has announced that the main building in its upcoming T8 8.6-Gen inkjet printing IT AMOLED Production line in Guangzhou has been topped out. The company is now starting to build the cleanrooms inside the building, install the power system, and then install the core equipment.

TCL CSOT started constructing this building on November 30, 2025, and it took only 151 days to complete the main structure - this is said to be a new industry record - and is actually ahead of TCL CSOT's original schedule.

According to Sigmaintell, global OLED smartphone shipments reached 202 million units in Q1 2026, up 4.7% from Q1 2025 (193 million) thanks to higher demand for flexible AMOLED panels from Apple and Samsung Electronics, and also from Chinese smartphone brands.

Rigid OLED shipments dropped 33% from last year, but flexible OLED shipments rose 19%. The market share of Korean flexible OLED makers (Samsung Display and LGD) rose to 42.8%, up 8% from last year. Samsung Display shipped 55 million OLED panels in Q1 2026 - up over 50% from last year.

Omdia estimates that producing a laptop OLED panel using inkjet printing is about 30-35% lower in cost compared to traditional FMM production. Both technologies are expected to slowly reduce production costs, but the gap will remain rather constant, at least in the next 3 years.

Inkjet printing, according to Omdia, provides many advantages over conventional technologies. - advantages in red, green, and blue (RGB) subpixel patterning, greater material utilization, flexibility, panelization, and larger pixel apertures. At the same time, equipment and maintenance costs are lower than those required by FMM processes. All of this translates to lower production costs.

TCL CSOT is showing a 2.24" 1700 PPI Real-RGB G-OLED display. This is the highest density such display that TCL has shown to date, improving on its previous 1,512 PPI AMOLED display showed in 2025.

The 1700 PPI 120Hz display (2.24" 2600x2784) is deposited on a glass substrate. Targeting XR applications, TCL's high-resolution AMOLEDs should offer a lower-cost solution compared to OLED microdisplays.

Tianma is showing its latest OLED display prototypes at SID Displayweek 2026. First up we have a 6.58" AMOLED that adopts Tianma's latest U11 OLED stack, which utilizes a a PSF emitter system (likely green, but Tianma did not specify) and also a new fluorescence emitter system which Tianma calls NFT (New Fluorescent Technology) based on New Fluorescent Blue (NFB). 

Tianma says that the new NFT device structure improves exciton utilization efficiency, and utilizing these new technologies, the U11 reduces overall power consumption by approximately 12% compared to Tianma's previous stack, while doubling lifespan. The optimized RGB spectrum and light-extraction design also enable an ultra-low blue-light ratio while maintaining high efficiency.

A couple of months ago we posted an article, discussing India's goal of becoming a global display producer, speculating on whether the country will bet on LCD, OLED or microLED technology.

Today we hear that the country has approved its first display project, Crystal Matrix's $336 million miniLED/microLED project.
