I've just realized that I've forgotten a big something in my previous calculation of theoretical LCD efficiency. Color filters may have something like 30% efficiency, but behind them there is another big power-waster : the back polarizing filter, which eats 50% of the incoming light's energy if it is absolutely perfect. This makes the theoretical LCD efficiency, given that perfectly lossless components of equal refraction index are used, 15%. With this in mind, 5% for a real-world device is not even that bad...

About your explanation of TMOS now : interesting use of frustrated TIR ! I'm still amazed that a mechanical device can be fast and efficient enough to achieve good display refresh rates with low power consumption, even though I shouldn't be since I've seen the IMOD/Mirasol demos...

Wonder for how long these capacitive MEMs they use in the FTIR layer can retain their state in real-world use. If it can withstand low refresh rates when displaying a still image, this tech could be used to build some nice transflective screens.

Also, I didn't know that it's transistors that are the biggest component which ends up limiting DPI in screens, so thanks for the information.

Big thing which I don't like in this screen concept is that it's yet another display device where displaying black and other dark colors is a huge power waste. Guess only OLED can do something about this...

Another question is that of vision angles. If you look sideways at a TMOS screen, you see light that has traveled a longer path inside of the FTIR layer, and which will thus be darker.
