Am I correct to assume that a Passive-Matrix LCD would not have a SAH (sample-and-hold effect)? If so, I will have more questions later. Thank You :)

Am I correct to assume that a Passive-Matrix LCD would not have a SAH (sample-and-hold effect)? If so, I will have more questions later. Thank You :)Yes you are correct IMO. To be clear though, all displays have a SAH effect. It is just that Passive Matrix creates a very short pulse of light per frame which greatly reduces the SAH effect (below a threshold which most people can detect).

Problem is that using Passive Matrix and Liquid Crystals together is not a very good idea because the relatively slow response of the crystals makes it nearly impossible to use passive matrix driving as the voltage on the cell is only applied for a very short time. This will cause severe ghosting and very low brightness compared to Active Matrix.

A way around this is to use active matrix but to limit the duty cycle to 20% or so to "emulate" passive matrix.

And there is some talk of using passive matrix in combination with a bi-stable liquid crystal which maintains its orientation once activated. Although this would cause SAH problems :)

In the last year of production on color CSTN, the response speed was 150mSec. So, no matter the interest, the technology is dead and was fatally flawed in its ability to produce saturated colors, view angle, response speed, and it needed a variable drive voltage when the ambient temperature changed. Aside from that, it was great.

It takes nearly 10 refresh scans to fully rotate the LCD the 230 degrees required to do its job.

I don't get the question.

A way around this is to use active matrix but to limit the duty cycle to 20% or so to "emulate" passive matrix.

I have been dreaming about this since I found out current 60hz LCDs have too much blur for me to thoroughly enjoy fast moving content on them. Any chance we see something like this in the near future? Of course this introduces flicker and we all know LCD manufacturers can't give that up.

By the way here is something that might give the original poster hope:
