2. ABSTRACT INTRODUCTION WORKING
• E-Paper is portable, re-usable and storage display device
• It works by using E-Ink technology
• It is Non-backlit
• E-Paper is of two types i.e., Non-flexible and flexible
• Flexible displays uses plastic substrates and plastic
electronics for the display backplane

3. ABSTRACT INTRODUCTION WORKING
• Electronic paper was first developed in the 1970s by Nick Sheridon
• Gyricon is used only for black and white display
• Latest E-paper displays were light weight, efficient and clear
resolution
• Because of high storing capability, it consumes less power

4. ABSTRACT INTRODUCTION WORKING

5. ABSTRACT INTRODUCTION WORKING
• When a voltage is
applied
across two plates, the
particles will migrate
electrically to the plate
bearing the opposite
charge from that on the
particles
• There is a slightly negatively charged ink between two
arrays of electrodes
• The electrodes are charged to repel the ink to the surface,
effectively turning them ON and OFF

6. ABSTRACT INTRODUCTION WORKING
• When particles are located at the
front side of display, it appears
white.
• When particles are located at rear
side of the display, it appears
dark.
• The display forms visible images
by rearranging charged particles
using an applied electric filed

7. ABSTRACT INTRODUCTION WORKING
USING COLOUR FILTERS
• It uses microcapsules technology to produce colour
display
• Every colour has some particular voltage levels

8. APPLICATIONS ADVANTAGES DISADVANTAGES
Digital ID Tags
Digital Price Boards
Books, News Papers
and
Magazines
Mobile phones and
gadgets with flexible display
units

9. APPLICATIONS ADVANTAGES DISADVANTAGES
•Potential flexibility
•Less power consumption
•Battery powered
•Paper Consumption can be reduced

10. APPLICATIONS ADVANTAGES DISADVANTAGES
•Less attractive to LCD & LED
•Difficult to read in low lighting
conditions

11. FUTURE SCENARIO
•It could change the way you receive daily news
paper
•Textbooks could be digitized on E-Paper

12. CONCLUSION
• Since every development in the past few years has
revolved
around mobility & ease of information flow, E-paper seems
to fit right into the mould for the future
• Gadgets can be replaced by E-Paper display to reduce
battery consumption and to read easily under sunlight
