|
| Put a different way: when light falls on an eInk "pixel" it

| we see the vast majority of surfaces in the world: they absorb
| light and then re-emit it, possibly changing its intensity and

| not reacting significantly to the ambient light that falls on
| them. But if one we able to measure the light falling on each
| individual pixel of an OLED, one could adjust each pixel to
| mimic the behavior of a physical object. It could "simulate"
| eInk, so to speak. If the mimicry is close enough, then there's
| no fundamental difference between the two. They'd both be
| emitting the same frequency and intensity of light.
|
| In fact I recall a post, mostly likely here on HN: Someone took

| ambient light sensors, put it in a decorative art frame and
| hung it on the wall. With some software and calibration they
| were able to get it to look convincingly like a real piece of
| art, fooling many of their guests.
|
| eInk has been around for decades now and has remained an
| obscure niche. It's possible we'll see a renaissance for it,
| with the patents hopefully expiring? But there's no reason we
| shouldn't also be pursuing better ambient light calibration for
| our existing displays.
|
| P.S. It's not accurate to say that eInk is a "reflective"
| display, as it does not primarily reflect light. Otherwise it
| would look like a mirror. But saying "emissive" versus
| "reflective" is common parlance for differentiating
| technologies like eInk from technologies like LCDs and OLEDs.
| Nitpicking the terminology is not particularly helpful though.

|
| There is one specific difference between the light from LED

| adjusting the polarity of the backlighting and then passing
| it through a polarizing filter. An e-ink display image is
| unpolarized light. It's not clear whether the polarity of LED
| has the potential to cause eye strain or other negative
| effects, but it is certainly a quantifiable difference.

| Too bad nobody actually makes one. There's no way to buy a
