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.
