LGD's Automotive OLED receive TÜV Rheinland Product Carbon Footprint certification

LG Display announced that its automotive OLED displays (both its flexible P-OLED panels and its rigid ATO panels) received TÜV Rheinland’s ‘Product Carbon Footprint’ certification, a milestone marking compliance with emissions standards across the product’s lifecycle. LGD's automotive OLEDs are highly efficient, and both utilize the company's tandem OLED structure.

LGD says that it recently introduced a new film to its automotive OLEDs, developed in-house, "Light Control Film Integration Technology" that enabled it to reduce its automotive OLEDs carbon emissions by up to 18% compared to its previous OLEDs.  This method also has the added benefit of effectively streamlining the manufacturing process, further reducing product weight, and improving power efficiency compared to conventional panels that use external films.

Samsung and LG begin producing 11" and 13" tandem LTPO AMOLED displays for Apple's iPads

Reports from Korea suggest that Samsung Display and LG Display are starting to produce AMOLED displays for Apple's future iPads, to be announced later this year. Samsung is set to produce 11" LTPO AMOLED displays, while LG Display is producing displays for the 13" model (but LGD will also produce 11" AMOLEDs in the future for Apple). 

Apple iPad (8th-Gen)

The Elec says that both Korean makers developer 11" and 13" displays, but for some unknown reason only LGD will produce the 13" displays. This could change in the future, of course. One reason could be that LG Display has more experience with tandem OLED architectures (developed originally by LGD years ago for automotive OLEDs).

TCL CSoT shows tandem and LTPO OLED display prototypes

TCL is demonstrating a new 14" 4K 120Hz flexible AMOLED display that adopts a tandem display structure. The tandem structures enabled a reduction in power consumption of over 30%, an extension of the display's lifetime (3.5X) and a peak brightness of over 2,500 nites.

TCL was also showing a new 6.36" 1200x2670 LTPO AMOLED display, that features the company's new frequency division technology and self-developed frequency scanning circuits. Coupled with an ultra-low power consumption IC, it offers 15-20% power savings compared to TCL's standard AMOLEDs.

DSCC: the OLED materials market to grow from $1.7 billion in 2023 to $2.7 billion in 2027

DSCC estimates that the market for OLED evaporation materials (i.e. OLED stack materials) will reach $1.7 billion in 2023, and will grow to $2.7 billion in 2027 (a 11% CAGR from 2023). If UDC will succeed to commercially introduce a blue phosphorescence material, revenues can even be much higher.

OLED materials used in TV applications (and other large-area applications) will grow from $305 million in 2023, to $492 million in 2027, a 13% CAGR. DSCC also sees very fast growth in material used to produce tandem-structure IT displays, which will grow at a 79% CAGR to reach $443 million in 2027.

LG Display reveals its automotive display strategy and its latest OLED customers

LG Display detailed its latest automotive display strategy. The company is now offering three product family. For luxury flagship cars (over $80,000 in cost), the company is offering its P-OLED flexible panels, that offer high performance coupled with design freedom.

For premium cars ($50,000 - $80,000) the company offers rigid OLEDs, that offer high image quality and a tandem OLED architecture for increased efficiency and lifetime. These displays are lower in cost compared to LG's P-OLEDs, and LG brands these as ATO (Advanced Thin OLEDs) as they adopt TFE encapsulation over a glass substrate. For mass market cars ($30,000 - $50,000) LGD offers LTPS LCDs.

Researchers find that adding an ultra-thin metal layer can dramatically enhance the lifetime of tandem OLED devices

Researchers from South China University of Technology and Guangzhou New Vision Opto-Electronic have found that the lifetime and current efficiency of a tandem OLED device can be greatly improved by adding an ultra-thin Ytterbium (Yb) metal layer through the charge generation layer (CGL).

The experiments detail an ultra-thin Yb metal layer with low work function, high transmittance, and large atomic radii, added to a light-green tandem OLED devices. The new device exhibited a lifetime of 308 hours (T90) at an initial brightness of 10,000 cd/m2 - which is 362 times (!) longer than that of a similar device without the Yb layer (T90 = 0.85 hours). The lifetime of the same material in a single-layer configuration (not a tandem device) was 49 hours (T90).
