She currently is the founder and CEO of Openwater , a new moonshot program and here is what it promises. Openwater is creating a device that can enable us to see inside our brains or bodies in great detail. With this comes the promise of new abilities to diagnose and treat disease and well beyond — communicating with thought alone. Mary Lou believes her technology will be In the early years of the e-reader revolution there were a few companies all going neck and neck, trying to outdo each other.
Pixel QI, Bridgestone, E Ink and Plastic Logic were all trying to employ different technologies to convince companies to use their technology and cornerstone the market. One of the big new factors in this technology is the. It can do partial page updates, full page updates, and supports touch screen and stylus interactions.
The screen technology can support from 8 inches all the way to 21 inches and does around 4 levels of gray-scale. They started making products in and decided to close up shop in Plastic Logic has been around for almost twenty years and they have no commercial success stories, although the company is still developing new products. They raised hundreds of millions of dollars over the years and in they tried to release the Que e-reader, but it was a commercial failure. This was the last hardware they would ever develop themselves and instead pivoted to make panels for other companies.
They closed down US operations in Mountain View in In Plastic Logic split into two companies, the main Plastic Logic brand was relocated to their production facility in Dresden Germany and the other company, FlexEnable focuses on research and is based in Cambridge.
So what are Plastic Logic screens all about? This means that a flexible backplane can now be coupled with a flexible display medium, such as flexible OLED or flexible EPD , to create a fully flexible display. One of the downsides of the Plastic Logic brand is that they do not have any flagship products that employ their technology that can be used for marketing material, or to generate media buzz.
Likely their most successful venture was from L! It only raised a paltry k US over the a period of about a year and missed almost all of their shipping dates. Some of the other little things they have done is make reusable delegate badges and a screen for the LandRover team for a boat UK boat race.
Another use case benefiting from the improved display density would be applications where accurate lines and measurements are critical, such as ePaper rulers, portable mapping or CAD drawings. LG first entered the flexible e-paper arena in and developed a screen that was crafted from a flexible plastic substrate, the display measuring 0. LG also has made it fairly durable with it being able to easily withstand dropping it from up to six feet.
The battery life is also fairly amazing with two or three months of usage. Russian based e-reader company Wexler was the only company to adopt the LG technology into their Flex One.
The screen was six inches and bended in 40 degree angles. The e-Paper was a bit different from traditional e-Ink, but provided the same overall experience. It was very easy on the eyes and did not reflect direct sunlight. The screen is crafted from a flexible plastic substrate, the display measuring 0. They realized the e-reader market was quickly becoming dominated by E-Ink and decided to enter the smartphone market using a flexible OLED design, since they had years of experience on it.
They are now one of the biggest players in this market segment. Mirasol spent almost four years developing its screen technology, which was an alternative to Pixel QI and Color e-Paper. What went wrong with the screens? Mirasol screen technology was developed to draw less power and be viewable in direct sunlight.
Qualcomm had grand ambitions to usher in a new era of smartphone, tablet, and e-reader screens. The company spent almost 1 billion dollars on a dedicated factory in Taiwan to produce the screens. All of these devices ran on the Google Android operating system and were very unique in the marketplace. Qualcomm was estimated to have lost close to million dollars in due to the Mirasol fiasco. The company announced a few months ago that it was abandoning the technology in its current form.
So what went wrong? Mirasol screens were only able to produce 60 Hz video, which quickly drained the battery. When we reviewed the Kyobo e-reader, we noticed that colors looked washed out. Liquavista was founded in as a spin-off from Philips. It was purchased by Samsung in and then sold to Amazon a few years later. Liquavista is based on Electrowetting, which modifies the surface tension of liquids on a solid surface by using a voltage. When a voltage is applied, the wetting properties of a hydrophobic surface can be modified and the surface becomes increasingly more hydrophilic more wettable.
With Electrowetting displays, the modification of the surface tension is used to obtain a simple optical switch by contracting a colored oil film through applying a voltage. Without a voltage, the colored oil forms a continuous layer and the color is visible to the consumer. When a voltage applied, the oil is displaced and pixel becomes transparent. When various pixels are independently activated, the display can show any kind of content including text, images and video.
Thanks to the high switching speed of electrowetting and its applicability to small pixel dimensions, electrowetting displays support a fluent user interface and are ideally suited for information displays showing animated and video content. The essence of Electrowetting technology is that it is highly scalable. From a manufacturing point of view, it is easy for existing LCD plants to incorporate Electrowetting into its process.
It is basically the same entire procedure to create the screen, except instead of using Liquid Crystals they use a different fill. One of the huge benefits of Liquavista technology is that it is flexible, which means it is much more robust. If you have ever dropped an iPad or an iPhone, you know the LCD glass breaks rather easily because it is extremely inflexible. Amazon tried to make a go of Liquavista. They used a Chinese factory to make prototypes and built a management team in the Netherlands.
After two years of failure they decided to throw in the towel and dismantled the Liquavista offices in the Netherlands and moved all of the equipment out. All of the key executives working in the division have already been moved into other departments and Amazon has shut down all job listings to work on Liquavista. This is a serious blow to consumers that were hoping to see a color Kindle or Fire tablet employing Liquavista technology. E Ink was one of the earliest entrants to the burdening e-reader industry.
In E-Ink released Pearl and many other companies entered the e-reader space. It offered a higher contrast screen built with E Ink Pearl imaging film. Also in was the creation of the first colored e-paper, Triton.
It was able to display 4, colors, but few companies pulled the trigger to release a commercially viable e-reader. In E-Ink released Triton 2, but only Ectaco and Pocketbook released e-readers, soon after that Ectaco suspended making e-readers due to dismal sales.
