Cynora’s Claims vs. Reality
June 19, 2017
At Display Week, Cynora announced that it newest blue emitter was close to performance standards set for panel maker’s commercialization specs. They are shooting for an end of 2017 delivery. Using TADF technology the company claimed it had achieved 15% EQE, at 1000 cd/m2 with an emission peak at ~470nm and a lifetime of 90 hours at LT97 operating at 700 cd/m2. We checked with Samsung and LG regarding the closeness of the material to commercial specs. As we indicated previously, 460 nm (deep blue) is the requirement, not the sky blue of 470nm. It is a big challenge to go from 470nm to 460nm as several companies have experienced. The reported efficacy was only 50% of the spec but the lifetime was close. It is clear that Cynora has their work cut out for them if they intend to deliver at the end of 2017. Samsung started the trend with its Galaxy G8 and LG’s G6 did it, the iPhone 8 is expected to do it, the Essential essentially did it, and Google is also set to change the shape of the upcoming Pixel from a 9:16 to a 9:18 aspect ratio.
