VIDEO: Captured a high speed camera video of an LCD refresh in progress!

post #1 of 2
Thread Starter 
For my blog, I have started recording high speed videos of LCD display behaviors, thanks to my brand new Casio high-speed camera. This video was captured at 480fps, and catches an LCD refresh in progress:


This video shows the following:
- Typical 2007-era panel
- Pixel persistence leakage between frames
- Top-to-bottom refresh behavior
- Pixels are refreshing to white faster than to black.

Here's a second high speed video I created,
this time of a strobe backlight (ASUS VG278H LightBoost), captured at 480fps and 1000fps:

The high speed video also proves that strobing can be used to bypass pixel persistence.

It's one of the few computer monitors that has finally hit the market to have zero motion blur (CRT style smooth motion effect), good for FPS video gamers. It's a TN panel, so not as good color for PhotoShop or that sort, but it's one of the world's first "zero motion blur" LCD computer monitors and makes it one of the best non-CRT displays for fast-twitch action FPS gaming.

Several people in other forums (HardForum.com, overclock.net) have measured a PixPerAn readability score of 25 for ASUS VG278H and readability score of 30 for BENQ XL2411T, which is unprecedented for LCD and a world's first for commercially available LCD monitor to successfully reach that score in prad.de PixPerAn benchmark app -- Compare that to CRT which gets a benchmark score of 30 for motion clarity.
