What They Say
Semiconductor Today reported on a development of a full colour stacked RGB microLED display from Sundiode Inc, based in Silicon Valley. The display is built on a Si CMOS backplan from Jasper Display. It is 15.4 x 8.6mm format device. The firm oriiginally said that it had developed a technology with KOPTI of Korea in April. The pixels are said to be 100?m in size (0.1mm) and the pixel density is said to be 200ppi. (so presumably the pitch between the pixels is around 0.127mm).
On its website, the firm has a couple of videos that show the pixels in action.
The article said that the next phase of the development is to ‘significantly’ increase the pixel density.
What We Think
These barely qualify as microLEDs from our definition. I’m struggling to work out this class of display could be used. The ppi level is low, which means that a even a medium resolution data display is going to need a big CMOS backplane, which means an expensive device. So this is really just a ‘proof of concept’ rather than a usable device. (BR)
