Imod by shudhanshu agarwal
This seminar discusses interferometric modulator display (IMOD) technology. IMOD uses micro-electromechanical systems to produce colors through interference of light with very low power consumption, providing an always-on experience. An IMOD is a thin mirror fabricated on a transparent substrate, leaving an air gap that interferes ambient light to produce colors. IMOD has two states, open and collapsed, to generate color. It has advantages over LCD like lower power consumption, faster switching speed, better readability and contrast in all lighting conditions. Potential applications include MP3 players, games, cameras, TVs and more. IMOD technology is poised to replace existing displays with its always-on and high visibility features combined with extended battery

- 1. Seminar on Interferometric Modulator Display(IMOD) Shudhanshu Agarwal B.tech (EC-2011) Roll no.-1101421102
- 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
- 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.
