And Then There Was One – E Ink to Acquire SiPix

In another sign of consolidation in the emerging display technology industry, E Ink Holdings announced its intention to purchase SiPix Technology Inc. Combined with Bridgestone’s exit from the electrophoretic display (EPD) business, this means that E Ink, the first company to mass produce EPD, will be the sole manufacturer of the technology. SiPix started out in Silicon Valley and later sold a large share to and entered into a strategic partnership with AUO, mirroring the evolution of E Ink from a start-up to integration into the former PVI.

As opposed to Bridgestone, which attempted to produce large size, high-pixel density EPD, and to SiPix, which developed an approach to integrate pigments to produce full color, E Ink has focused on making incremental improvements to its EPD technology used in the Amazon Kindle, Barnes and Noble Nook, and other basic e-readers. These improvements have included higher reflectivity, higher resolution and gray scales, faster switching speeds, and the ability to pan across a page. These improvements, as well as E Ink’s ability to mass-produce the EPD material and integrate into a module, have enabled the company to ride the wave of e-readers and stay ahead of its competition.

The consolidation in EPD has been driven by the challenges of scaling up the different technology approaches, but perhaps more importantly by a shift in demand for EPD. Apple’s iPad opened up a new market for tablet PCs that could bridge the gap between mobile PCs and e-readers. Tablet PCs have offered consumers the ability to have full color and video capability, in a form factor that is similar to e-readers and with battery life, while not in weeks like e-readers, is good enough for most use cases.

Competition from tablet PCs has caused Amazon and Barnes and Noble, the leading customers for EPD, to offer tablet-like color e-readers using TFT LCD. This resulted in a significant slowdown in the EPDmarket starting at the end of 2011. According to our report, EPD revenues totaled $973 million in 2011, 43% Y/Y growth; however, Q4’12 revenues did not grow Y/Y, and Q1’12 revenues fell by 84% Y/Y. There are many other applications for EPD and other low-power display technologies, but e-readers accounted for more than 90% of EPD revenues in 2010 and 2011.

The impact of LCD (and potentially OLED) based tablet PCs on the demand for e-readers with low-power displays may also be impacting Qualcomm’s strategy for its MEMS-based mirasol technology. In the company’s Q3 earnings call, CEOPaul Jacobs announced that Qualcomm will be shifting to a licensing strategy for mirasol.

Qualcomm, which itself consolidated the MEMS display space through its acquisition of Pixtronix, has been building a fab to make the mirasol technology in Taiwan, but has not publicly commented on the fate of that fab or on their strategy for integrating Pixtronix, which has been developing a slightly different MEMS display technology. While Pixtronix has been focusing on licensing its technology to mobile phone display makers, Qualcomm has been trying to enter the e-reader market, announcing design wins with e-reader companies in China and Korea, but has not begun volume shipments.

    Great title, Paul. Such events seem to follow naturally from market dynamics. Given the price-performance range of LCD (passive-matrix, to active-matrix and reflective, transflective to transmissive), there may be few “quantum states” available to other technologies. In addition to this consolidation, I recall the Mirasol restructure and hear about Polymer Vision plus Liquavista challenges. I guess the bigger question is what quantum state AMOLED will occupy. DisplaySearch has some interesting developments to analyze this year and next!

    qualcomm shut down mirasol this year

    Is Mirasol display going the way of the SED TV?  Great potential but never making it to market?
