E-paper technology is designed in such a way to mimic the appearance of ordinary paper. E-paper consists of thin electronic display, unlike ordinary display it reflects sunlight that gives the readers a much more legible text to read.
E-ink capsules are made of titanium oxide which are optically reflecting, when voltage is applied some particles move to viewing side of the paper thus causing the reflection of light it appears white
If the particles move to the rear side of the display dark colored moves up front and hence it appears black,thus alternating the voltage a pixel is formed and hence the image.
Further different types of colors can be obtained by placing suitable color filters color filters above the spheres
Electrophoretic display:
E-paper technology consists E-ink suspened between two transparent electrode layers.E-ink capsules are made of titanium oxide which are optically reflecting, when voltage is applied some particles move to viewing side of the paper thus causing the reflection of light it appears white
If the particles move to the rear side of the display dark colored moves up front and hence it appears black,thus alternating the voltage a pixel is formed and hence the image.
Further different types of colors can be obtained by placing suitable color filters color filters above the spheres
Electrowetting:
Electrowetting displays consists of water and oil interface, when no voltage is applied oil is above water the hence the display appears black.
when voltage is applied the surface tension is disturbed an hence they are no longer in equilibrium, this cause the display to appear colored, it also has added feature the change is color is so fast, it is possible to display video contents.
Electrofluidic:
This is one type of electrowetting display in which there is a reservoir of aqueous pigments that come out behind the viewing part when voltage is applied and the display absorbs them and appears colored, bright corresponding to applied voltage.
when the voltage is removed the surface tension causes the pigments to recoil into the reservoir.
This technology may actually change the way in which our future generations read, mainly it puts an end to deforestation which is simply unthinkable
It would be great if it works out. Till then, Fingers crossed..!
ReplyDeleteit's al ready available as a prototype juz not yet in commericial use tats it....
ReplyDeleteIt's nice...but we can't afford gracious things...:-(
ReplyDeletewe can read in a dark room???
it's still in development phase so its a little bit costly
ReplyDeleteno it only reflects light doesn't produces it as other ordinary displays nd reading in a dark room is not good for ur eyes!!
good info to society's awareness.
ReplyDeletejust nw saw the blogging... such technologies are welcome.. but it may take considerable amount of time to make it commercially successful... anyway thanks for the information buddy.......
ReplyDeleteThis information in this blog is very useful to the viewers.
ReplyDeletethank you...:)
