Qualcomm buys MEMS display startup, reportedly for $175M

LONDON – Communications technology company Qualcomm Inc. has bought fabless MEMS display startup Pixtronix Inc. Qualcomm (San Diego, Calif.) confirmed the purchase but did not give any details and declined to discuss the price. However, reportedly, Qualcomm has paid between $175 million and $200 million.
Pixtronix (Andover, Mass.) was founded in 2005 by Nesbitt Hagood, chief technology officer. The company has developed a low-cost display technology based on the use of MEMS shutters that it appears would make a useful complement – or better alternative – to Qualcomm's own MEMS-based Mirasol display technology.
The Pixtronix display – called PerfectLight – is based on a MEMS-based digital micro shutter that modulates light from an RGB LED backlight. A high switching speed makes it suitable for applications ranging from full-speed video to e-reader operation and Pixtronix claimed that the display offered greater than 170 degree viewing angles, more than 3,000:1 contrast ratio and 24-bit color depth at one quarter of the power consumption of equivalent size and resolution liquid crystal displays.
The display is not in the market place yet but Pixtronix had developed a 5-inch diagonal display prototype with Chimei Innolux Corp. (CMI), a leading TFT-LCD manufacturer. Pixtronix was also developing a display for Hitachi.
Meanwhile, at about the same time Qualcomm was acquiring Pixtronix, Qualcomm subsidiary Qualcomm MEMS Technologies Inc. announced that a 5.7-inch Mirasol MEMS display technology is used in the Kyobe e-reader. Qualcomm acquired the Mirasol technology when it paid approximately $170 million in cash for the 86 percent of Iridigm Display Corp. that it did not already own.
The Mirasol display is reflective, which means it can save power by making use of ambient light and not requiring a backlight. However, it also means that the display is less bright and visually appealing than an emissive display.
Since its formation Pixtronix had raised more than $53 million in funding from such investors as Atlas Ventures, Kleiner Perkins Caufield & Byers, DAG Ventures and GoldHill Capital. It had about 50 employees and continues to operate as a subsidiary of Qualcomm at present.
Pixtronix entered the Silicon 60, EE Times' list of emerging startup companies at version 12.5, which is the subject of a detailed technology and employment digital edition which can be accessed via http://e.ubmelectronics.com/Silicon60/index.html

Interesting, Qualcomm seems to be broadening their display portfolio. Nice detail on the differences between their current Mirasol display technology and Pixtronix display. Thanks!

According to Pixtronic, the power saving is up to 60%. It is dramatic.
Pixtronix technology doesn't seem to be limited to mobile device. What's the show stopper to keep it from widely use in PC monitor and TV?

3000:1 contrast Ratio! I think the human eye can’t detect a contrast ratio that big isn’t?
This is a real big amount of money to pay for a company. Seems display technology for the mobile phones is a main asset. CDMA technology is dying; Qualcomm must get into new fields and be strong at it to remain the San Diego giant it is.

The power saving is good and cost factor is not mentioned.The 24 bit color depth and contrast ratio are good. The response time or the delay time is also not mentioned.

I'm a MEMS guy, and I'm interested in seeing how they solve the stiction problem. My understanding is that stiction is the primary reason the Mirasol display hasn't been released. I can see how the PicTronix approach could avoid stiction, but this is a problem you only really see once you're in low volume production and get a sense of how many pixels are stuck.

Wrong decision again, for display market, the cost is always above the product performance, not mention the poor performance of mems display.
I have no idea why the high level of Qualcomm never do market research before investment.

I thought after Mirasol experience, they would exit this area entirely, at least temporarily, but pause for longer time.
