future on display: long-lasting images save on power - digital advertising display

Living in a slow lane has its advantages.
Avoiding screen fashion that refreshes hundreds of times per second, Daniel Sachs, Kevin Qiu, and Tyler Hutchinson from the MIT camera culture group, junichiro Koizumi, graduate school of media design at Keio University in Tokyo, Japan, has built monitors that change every few hours.
The benefit of doing so, they say, is that energy efficiency is unmatched.
The slow display of the group uses less than 2 watts of power to display the image on a screen with a diagonal size of 3.
Standard LCD screen with 2 m-diagonal size only 1.
100 to 200 watts can be used for 3 metres.
Although there are low alternatives
Saakes's team said that power display technologies such as electronic ink or a gallbladder-like LCD display are difficult to expand without simply tiling a large number of smaller displays.
Therefore, their technology is more suitable for slow
Always changing.
On a digital display used to advertise or inform road drivers of driving conditions.
A layer of light on the screen
Sensitive paint, when exposed to ultraviolet rays, a reversible photoization reaction occurs, changing the color in the process.
The second layer of glowing paint exposed to ultraviolet light ensures that the screen can be used day and night.
The image is projected onto the display through the UV laser projector, which activates the material of the Display coating.
After the laser is turned off for an hour or more, the resulting image is still clearly visible.
With the reversal of the light reaction, it gradually disappears.
To prevent the image from being degraded by ultraviolet rays in the sun, a filter can be installed in front of the screen.
The image must then be projected from a laser mounted behind the screen.
The decline of the image is out of control and the team recognizes that this means that the ghost of the old image may keep the image refreshed.
They are working on photosensitive compounds for light reactions at different wavelengths, with the aim of creating a coating that can be turned off and turned on.
Since the coating material on the display surface forms an image, this technique can be applied to 3D objects.
This can be used in an engineer's model, for example, to display a virtual decal or logo.
But saakes's team pointed out that any such image could be short-lived because it's harder to protect images on 3D objects from over-saturation with UV filters. See more:
