2. 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

3. 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

4. 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

6. Basic structure of IMOD
Pixel
It consist of two states–
1 Open state
2 Collapsed
state

7. OPEN STATE

8. COLLAPSED STATE

9. Color Generation:

10. HYSTERISIS LOOP

11. 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

12. An LCD screen Vs IMOD screen which is
visible in sunlight

14. Advantages
 Speed
 Readability
 Less power consumption
 Consistent contrast quality
 Smoother animation

15. Applications
 MP3 player
 Gaming devices
 Digital camera
 Medical imaging
 DigitalTV and DVD players

16. 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.
