Low persistence is possible with OLED, but the monitor still has to be designed to support it. It's the same problem as pulsing a backlight, but now you have to pulse millions of LEDs. Easiest way to do that is to power the control elements of the panel separately from the rail that drives the luminous elements of the display, but if the panel manufacturer doesn't design it that way you're going to have a rough time modding a low persistence mode into it. Another option would be to turn a row off a few tens of microseconds after turning it on, this would likely halve the refresh rate at which the display controller can drive the panel. That might not be a problem if you're limited by the throughput of your computer to display interface.thatoneguy wrote:Sparky wrote:Connecting your device to the backlight would require modifying the monitor.
Right. That makes sense!
Would this perhaps be possible with self-emissive displays like OLED then?

but my idea is more of a "ghetto solution"...as in this supposed device might work well on some displays but might work like crap on other ones(or might even potentially bust them up...who knows)
How would that work exactly? Be specific. Why would a monitor designer make the backlight strobeable by an external device instead of just hooking it up to the panel driver? Why would they design the backlight driver to strobe if that's not a feature they intended to add to the display?I initially thought it would be somehow possible to control the main circuitry(that is driving the backlight on a LCD) through a USB or HDMI port(though of course the display and the circuitry inside it would have to be built with that in mind...if it is even possible in the first place)
