Re: Here's a real example of a 1000hz display... I think

the iphone 5/5s has about 55ms latency according to this: http://www.macrumors.com/2013/09/21/iphone-5-touch-screen-twice-as-fast-as-android-touch-screen/ Also, the smallest perceptivePixel multitouch display (27" I think) has around 10ms latency, you can kinda tell by looking at this video: http://...

idea to lower persistence in a 120hz DLP projector

Hello everyone, I have an infocus IN112 DLP projector(probably one of the cheapest 120hz low res projectors you can buy), I haven't checked its color wheel yet but if it were a 6 segment (RGBRGB) wheel would it be possible to lower its persistence if I blocked one of the RGB halves with black tape? ...

Re: 3d active glasses hack as personal shutters to lower per

I just re-read the mechanical shutters thread, I guess it was a while since I read it the first time.. sorry people, bad memory!

3d active glasses hack as personal shutters to lower persist

No I haven't done this yet, just wondering if its possible. The idea is as follows: Instead of a strobed backlight why not use a pair of 3d active glasses where instead of alternating each eye, the lenses open and close at the same time thus acting like the mechanical shutters someone talked about i...

Re: Here's a real example of a 1000hz display... I think

thats great, maybe we are not so far from having mobile devices with a perceived latency like the one they showed in the video, this would be awesome for using a stylus on a touchscreen. I have the feeling that maybe the researchers from the video knew nothing about low persistance and did get their...

Re: Here's a real example of a 1000hz display... I think

one more thing, based on the slo mo footage (which it says is slowed by a factor of 8) you can sorta determine how fast they recorded it. Assuming the framerate of the final video is 30fps , then 30 times 8 would be 240fps which is the framerate they captured the slo mo footage. Now, on every frame ...

Re: Here's a real example of a 1000hz display... I think

so what you mean by low persistency is that if you ran the display at say 120hz and flashed the cursor for 1ms your brain would interpret it as if though the cursor was 1 millimeter behind your finger ??? (if your finger was moving at 1 meter per second)

Re: LCD max theoretical refresh rate and does pixel size mat

cool, btw there's an LG HDTV(I think its LG) advertised as being 480hz, have you looked into that or do you think is marketing bs?

Re: Here's a real example of a 1000hz display... I think

Thanks for the responses, I'm not 100% sure they ran the thing at 1000hz, but these are the refresh rates I suppose they used: 100ms -> 60hz ?? (I think this is where my previous reasoning was a bit off, for 100ms latency you'd need a framerate of 10hz which it doesn't seem to be the case, maybe the...

Re: LCD max theoretical refresh rate and does pixel size mat

like you said, since mass is actually being moved inside the crystal wouldn't a smaller mass be easier to move? hence achieving faster transitions times? do smaller pixels (think retina displays) transition faster or are they driven with smaller voltages or they actually do change faster but compare...
