This document discusses e-paper displays. E-paper is a portable, reusable electronic display that uses e-ink technology and is non-backlit. It works by applying a voltage to migrate charged particles and form visible images. E-paper comes in both flexible and non-flexible types and has applications in digital tags, price boards, books, newspapers, magazines, and mobile phones. It offers advantages like flexibility, low power consumption, and reduced paper usage. Challenges include less attractive visuals compared to LCD and difficulty reading in low light. The future potential of e-paper includes digitizing textbooks and changing how news is delivered.

- 1. E-Paper Display By G.Varalakshmi (09MN1A0435)
- 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
