#Vision-correcting displays Researchers at the MIT Media Laboratory and the University of California at Berkeley have developed a new display technology that automatically corrects for vision defects no glasses (or contact lenses) required.
The technique could lead to dashboard-mounted GPS displays that farsighted drivers can consult without putting their glasses on
The first spectacles were invented in the 13th century says Gordon Wetzstein a research scientist at the Media Lab and one of the display's co-creators.
We have a different solution that basically puts the glasses on the display rather than on your head.
Wetzstein and his colleagues describe their display in a paper they're presenting in August at Siggraph the premier graphics conference.
The display is a variation on a glasses-free 3-D technology also developed by the Camera Culture group.
Essentially the new display simulates an image at the correct focal distance somewhere between the display and the viewer's eye.
The difficulty with this approach is that simulating a single pixel in the virtual image requires multiple pixels of the physical display.
which light would arrive from the same image displayed on the screen. So the physical pixels projecting light to the right side of the pupil have to be offset to the left
The use of multiple on-screen pixels to simulate a single virtual pixel would drastically reduce the image resolution.
and colleagues solved in their 3-D displays which also had to project different images at different angles.
The MIT and Berkeley researchers were able to adapt that algorithm to the problem of vision correction so the new display incurs only a modest loss in resolution.
In the researchers prototype however display pixels do have to be masked from the parts of the pupil for which they re not intended.
That requires that a transparency patterned with an array of pinholes be laid over the screen blocking more than half the light it emits.
instead using two liquid-crystal displays (LCDS) in parallel. Carefully tailoring the images displayed on the LCDS to each other allows the system to mask perspectives
Wetzstein envisions that commercial versions of a vision-correcting screen would use the same technique.
Indeed he says the same screens could both display 3-D content and correct for vision defects all glasses-free.
MIT researchers explain how their vision-correcting display technology works. The key thing is they seem to have cracked the contrast problem Dainty adds.
Dainty believes that the most intriguing application of the technology is in dashboard displays. Most people over 50 55 quite probably see in the distance fine

#Glasses-free 3-D projector Over the past three years, researchers in the Camera Culture group at the MIT Media Lab have refined steadily a design for a glasses-free, multiperspective, 3-D video screen,
which are like tiny liquid-crystal displays (LCDS) positioned between the light source and the lens. Patterns of light and dark on the first modulator effectively turn it into a bank of slightly angled light emitters that is,
The screen combines two lenticular lenses the type of striated transparent sheets used to create crude 3-D effects in,

#High-resolution patterns of quantum dots with e-jet printing A team of 17 materials science and engineering researchers from the University of Illinois at Urbana#Champaign and Erciyes University in Turkey have authored High-resolution Patterns of Quantum dots
Are formed by Electrohydrodynamic Jet Printing for Light-emitting diodes. Their paper was published in Nano Letters an ACS journal.
and operating conditions that allow for high-resolution printing of layers of quantum dots with precise control over thickness and submicron lateral resolution and capabilities for use as active layers of QD light-emitting diodes.
The thickness can be controlled through a combination of printing parameters including the size of the nozzle the stage speed ink composition and voltage bias.
Their work on high-resolution patterns of quantum dots is of interest as it shows that advanced techniques in e-jet printing offer powerful capabilities in patterning quantum dot materials from solution inks over large areas.
E-jet printing refers to a technique called electrohydrodynamic jet described as a micro/nanomanufacturing process that uses an electric field to induce fluid jet printing through micro/nanoscale nozzles.
The resolution of conventional ink jet-printers printers is limited. For the past seven years she said Rogers has been developing the electrohydrodynamic jet printing method.
This kind of printer works by pulling ink droplets out of the nozzle rather than pushing them allowing for smaller droplets.
An electric field at the nozzle opening causes ions to form on the meniscus of the ink droplet.
Then a tiny droplet shears off and lands on the printing surface. A computer program controls the printer by directing the movement of the substrate
and varying the voltage at the nozzle to print a given pattern. Dot line square and complex images as QD patterns are possible the researchers said with tunable dimensions and thickness.
They wrote that these arrays as well as those constructed with multiple different QD materials directly patterned/stacked by e-jet printing can be utilized as photoluminescent and electroluminescent layers.
Writing in IEEE Spectrum on Monday Prachi Patel similarly made note that Quantum dots (QDS) are light-emitting semiconductor nanocrystals that used in light-emitting diodes (LEDS) hold the promise of brighter faster displays.
In the IEEE story headlined High-resolution Printing of Quantum dots For Vibrant Inexpensive Displays Patel said these researchers repurposed a printing method which they devised for other applications.
Inkjet printers usually have a few hundred nozzles said Patel. The difficulty with the e-jet printing method is that the electric field at one nozzle affects the fields of neighboring nozzles.
They are trying to figure out how to isolate nozzles in order to eliminate that crosstalk. Explore further:

and operating conditions that allow for high-resolution printing of layers of quantum dots (QDS) with precise control over thickness and submicron lateral resolution and capabilities for use as active layers of QD light-emitting diodes (LEDS).
The shapes and thicknesses of the QD patterns exhibit systematic dependence on the dimensions of the printing nozzle and the ink composition in ways that allow nearly arbitrary systematic control when exploited in a fully automated printing tool.
Sequential printing of different types of QDS in a multilayer stack or in an interdigitated geometry provides strategies for continuous tuning of the effective overall emission wavelengths of the resulting QD LEDS.

and active electronics via 3-D printing (Phys. org) As part of a project demonstrating new 3-D printing techniques Princeton researchers have embedded tiny light-emitting diodes into a standard contact lens
Kong the lead author of the Oct 31 article describing the current work in the journal Nano Letters said that the contact lens project on the other hand involved the printing of active electronics using diverse materials.
Mcalpine said that one of 3-D printing's greatest strengths is its ability to create electronics in complex forms.
and then stacks them into three dimensions 3-D printers can create vertical structures as easily as horizontal ones.
To conduct the research the team built a new type of 3-D printer that Mcalpine described as somewhere between off-the-shelf and really fancy.
and build the new printer which Mcalpine estimated cost in the neighborhood of $20000. Mcalpine said that he does not envision 3-D printing replacing traditional manufacturing in electronics any time soon;
instead they are complementary technologies with very different strengths. Traditional manufacturing which uses lithography to create electronic components is a fast and efficient way to make multiple copies with a very high reliability.
Manufacturers are using 3-D printing which is slow but easy to change and customize to create molds and patterns for rapid prototyping.
Trying to print a cellphone is probably not the way to go Mcalpine said It is customization that gives the power to 3-D printing.
In this case the researchers were able to custom 3-D print electronics on a contact lens by first scanning the lens and feeding the geometric information back into the printer.
The new technique could also be used to create nanoscale inkjet printers for printing electronics or biological cells or to create antennas or photonic components.

and computer screens may seem worlds apart but they're not. When associate professor Qi Hua Fan of the electrical engineering and computer science department set out to make a less expensive supercapacitor for storing renewable energy he developed a new plasma technology that will streamline the production of display screens.

#First graphene-based flexible display produced A flexible display incorporating graphene in its pixels'electronics has been demonstrated successfully by the Cambridge Graphene Centre and Plastic Logic,
