"Cynora says it will also 'soon' follow with a deep-blue TADF solution" - these guys and their claims........curious if this breakthrough is overrated or if its significant

Cynora achieves breakthrough in its green TADF material, test kits are now available for display makers

Posted: 22 Jan 2021 04:22 AM PST

OLED material developer Cynora announced that it achieved a breakthrough in its deep-green TADF material, which it brands as cyUltimateGreen. The new material delivers an efficiency of over 20% (EQE), a lifetime of 400 hours (LT95@15mA) and a color point and emission spectrum that matches today's DICI-P3 standard (Cynora does not specify the exact number).

Cynora further announced that is now making test kits of the new deep-green emitter available to its customers. Display makers can now start testing and verification using the new material. Cynora says it will also 'soon' follow with a deep-blue TADF solution.

400 hours? Is that a typo or am I missing something in the details (not very difficult)?

The 400 hours is a LT95 value. That means that it has lost 5% of its initial brightness after 400 hours.


The odd part about the specs is that it lists the LT95 value at 15mA. Normally, lifetime is listed as a function of brightness (1000 nits is fairly standard). The fact that they went with a non-standard spec makes me suspicious. If it is measured at 1000 nits then it might be enough for commercial production.

Any thoughts Zikzak, Evan, or Ynot? Is there a way to translate the current into a standard brightness number?

Cowen upgrades iPhone 12 build forecasts over continuing high demand

High demand for the iPhone 12 has prompted Apple to increase its build orders for the March quarter, Cowen analysts claim, with sales in China said to be a highlight of the quarter's finances.

In a smartphone build update report from Cowen seen by AppleInsider, analysts say they have upgraded their forecast for the March 21 quarter for the third month in a row. Cowen currently believes Apple intends to produce 55 million iPhone units, a 49% year-on-year increase for the quarter, and up from 51 million forecast by the firm one month ago.

The increase in units is driven by higher demand for three of the four iPhone 12 models, with the iPhone 12 itself said to make up 2 million of the extra units, while the iPhone 12 Pro and iPhone 12 Pro Max each added 1 million to the total. The iPhone 12 mini estimates are supposedly unchanged from Cowen's previous forecast.

A highlight of its findings is claimed to be Apple's performance in China. The latest CAICT data is said to show 6 million iPhone units were sold in China in December, which is both a multi-year high for Apple and representing a market share of 20%.

The good news in China occurs during a time when overall smartphone shipments in the country are slipping, down 10% in December on a month-to-month basis and down 13% year-on-year to 26.6 million units. Approximately 6 million of these units were for foreign brands, with Apple consuming the vast majority of that segment.

Overall iPhone builds for the December quarter are said to be 79 million units, an increase of 13% year-on-year. The proportion of iPhone 12 units is said to be more concentrated than usual, with models thought to make up 82% of builds in the quarter, up from the average of 74% for the last two release cycles.

The forecast seems to correlate with other reports on iPhone demand and sales, including those of other analysts. Previously it was claimed Apple was increasing orders for the first half of 2021, a year-on-year increase of 30%, with the current generation also believed to be taking up a larger proportion of iPhone sales.

Apple is set to announce its December quarter financial results on Wednesday. AppleInsider will be reporting on the results and the subsequent analyst conference call.

Breakthrough in TADF green emitter-----No secret that UDC has been looking at TADF for use with phosphorescent emitters.

Maybe the TADF will be used in conjunction with UDC green to enhance UDC green.

Looking over some of Cynora's patents they have also been doing the same. Interesting that they mention OVJP

Example: cynora

In a preferred embodiment, at least one of the emitter compounds (a) and (b) is a thermally activated delayed fluorescence (TADF) emitter. In a more preferred embodiment, both emitter compounds (a) and (b) are thermally activated delayed fluorescence (TADF) emitters. In an alternative more preferred embodiment, emitter compound (a) is a thermally activated delayed fluorescence (TADF) emitter and emitter compound (b) is a fluorescence or phosphorescence emitter. In an alternative more preferred embodiment, emitter compound (a) is phosphorescence emitter and emitter compound (b) is a thermally activated delayed fluorescence emitter.

. Exemplarily, the following combinations may be chosen: [0069] (i) a combination of a higher energy TADF emitter as compound (a) which also feeds the excited singlet and/or triplet state of a lower energy phosphorescent emitter (compound (b)): the emission is a variable composition of TADF from compound (a) and phosphorescence from compound (b); [0070] (ii) a combination of a phosphorescent emitter (compound (a)) which also feeds the excited singlet and/or triplet state of a TADF emitter (compound (b)), wherein several energetic alignments of the excited singlet and triplets states of compound (a) and (b) are possible

Alternatively, the layers in the context of the present invention, including the light-emitting layer B, may be prepared by other methods based on liquid processing such as, e.g., casting (e.g., dropcasting) and rolling methods, and printing methods (e.g., inkjet printing, gravure printing, blade coating). This may optionally be carried out in an inert atmosphere (e.g., in a nitrogen atmosphere).
Alternatively, the layers in the context of the present invention, including the light-emitting layer B, may be prepared by any other method known in the art, including but not limited to vacuum processing methods well-known to those skilled in the art such as, e.g., thermal evaporation, organic vapor phase deposition (OVPD), and deposition by organic vapor jet printing (OVJP).

Universal Display price target raised to $260 from $204 at CitiCiti analyst Atif Malik raised the firm's price target on Universal Display to $260 from $204 and keeps a Buy rating on the shares. The analyst updated estimates and price targets across semiconductor equipment and components to align with Citi's updated wafer fab equipment estimates and expanded multiples driven by "strong" near term capex spend

Instead of doing a survey, oled-a should have just looked at the prior posts in their blog. They would see that lifetime is well beyond that.
