E-Paper Display

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

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

ABSTRACT INTRODUCTION WORKING

ABSTRACT INTRODUCTION WORKING

• 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

• 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

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

ABSTRACT INTRODUCTION WORKING

• It uses microcapsules technology to produce colour display

• Every colour has some particular voltage levels

USING COLOUR FILTERS

Digital ID Tags

Digital Price Boards

Books, News Papers and Magazines

Mobile phones and gadgets with flexible display units

APPLICATIONS ADVANTAGES DISADVANTAGES

APPLICATIONS ADVANTAGES DISADVANTAGES

•Potential flexibility

•Less power consumption

•Battery powered

•Paper Consumption can be reduced

APPLICATIONS ADVANTAGES DISADVANTAGES

•Less attractive to LCD & LED

•Difficult to read in low lighting conditions

FUTURE SCENARIO

•It could change the way you receive daily news paper

•Textbooks could be digitized on E-Paper

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
