PSP 3000 - Screen Comparison With Slim & Lite + Subpixel Closeups
Monday, February 16th, 2009
WATCH IN HIGH QUALITY! And stick ’til the end! The final 2 images are annotated to show the problems with both screens.

In the few days since I made this video and the photos here ( http://picasaweb.google.com/xythen/PSP3000# ) the full story has emerged and Sony has made a public statement about the issue. So here are the facts:
Firstly, to clear up some misconceptions, the “scanline” issue and the “interlacing” issue are two COMPLETELY separate problems. The “scanline” artifact manifests as visible STATIC black lines across the entire screen which are constantly visible. This is due to the new subpixel structure of the LCD screen. The “interlacing” artifact is visible during MOTION, and appears as jagged lines (sometimes called a “comb artifact”), and is caused by the LCD updating pixel rows by odd then even lines, instead of progressively (sequentially). I’ve been told by an engineer who works with mobile devices that this is often done to reduce power consumption (displaying 60 fields a second instead of 60 frames). Could this be how those Japanese engineers managed to get battery life equal to the PSP-2000..?

Lastly, Sony has admitted this is a “feature” (ugh!) of the new LCD screen. This means it was a conscious decision on Sony’s part to use a technology which generated these artifacts, no doubt to cut costs, and therefore happens on ALL PSP-3000s. If it doesn’t happen on yours it just means that you can’t see it, so count yourself lucky!
I didn’t make this video to “put people off” buying the PSP-3000, I just think that people have the right to be fully informed about a product before slapping down £150 only to be greeted with some unexpected “features”. In my opinion it is still an overall improvement over the PSP-2000, but I’d recommend you demo a unit before buying to see if the screen problems are noticeable to you.
