The lack of transflective and reflective display in common use is a mystery to me too -- while e-ink dominates on power usage and contrast, reflective and transflective displays (potentially) allow much greater pixel density and refresh rates, and the power requirements keep going down to the point where I think that they would be competitive.
- semi-extrinsic 2y agoAdding to the mystery, transflective is the only game in town for boat applications. You can get a nice fish finder like the Lowrance Hook Reveal 7 (I have one) with a 800x480 7" transflective screen for $290. That is including the external ultrasound transducer, signal processing chips, CPU, memory etc. So the display itself can't be much more than $100. The resolution is not huge, but still.

- ThrowawayR2 2y agoI have one of the reflective LCD monitors previously discussed on HN. I think many people are underestimating how low the contrast is for RLCD as a computer/tablet display. In sunlight, it works well. After sundown though, you need to provide rather bright illumination to maintain that contrast and that's probably going to interfere with sleep. The angle of incidence for the illumination matters as well. The farther off the perpendicular, the less light is reflected so that external side lighting like a LED bar pretty much doesn't work at all. It's not a drop-in replacement for a conventional monitor unless you only plan to work during daylight hours or in very well illuminated room or are willing to accept some workarounds after dark.
