Introduction

Wireless communication is an essential and continuously expanding part of modern life

Smart phones present a number of challenging requirements on the display module , such as low power consumption , video quality speed

To meet these requirements IMOD technology came into picture

What is IMOD

IMOD is a new display technology that produces fantastic colours by exploiting the physical effect of interference of light with very less battery power consumption

IMOD displays , based on MEMs(micro-electro-mechanical system technology), offers users an Always on experience with paper like readability in almost all ambient conditions

HOW IT WORKS An IMOD is a flexible thin mirror

fabricated on a transparent substrate leaving an air gap of a few hundred nanometres between the thin film and substrate

When ambient light enter this cavity it interferes with itself producing iridescent colours similar to that of butterfly wings

Basic structure of IMOD Pixel

It consist of two states–1 Open state2 Collapsed state

OPEN STATE

COLLAPSED STATE

Color Generation:

HYSTERISIS LOOP

IMOD TECHNOLOGY Vs LCD

It has low power consumption IMOD displays are comparatively less

complex IMOD displays change there state in

10usec compared to LCD that takes roughly

10 millisecond

An LCD screen Vs IMOD screen which is visible in sunlight

COMPARISION BETWEEN POWERCONSUMPTION OF LCD & IMOD

Advantages

Speed Readability Less power consumption Consistent contrast quality Smoother animation

Applications

MP3 player Gaming devices Digital camera Medical imaging Digital TV and DVD players

Conclusion

According to consumer research the demand and quickly adopt mobile products with an Always –on display , sunlight view ability and extended battery life will replace existing technologies.
