Interlacing Artifacts Show Up In New PSP-3000 LCDs

Posted by x3sphere at October 16, 2008, 8:32 pm

A number of users over at the official PlayStation forums are reporting that the LCD screen found in PSP-3000 units has poor de-interlacing quality, resulting in a somewhat noticeable reduction of image quality in fast-moving sequences displayed on-screen.

Forum user Prothean supplied a video clip that shows the aforementioned issue in action. As you can see, scanlines are visible when moving between icons in the XMB. The same effect is nowhere to be seen on the PSP-2000 unit, which is compared to a 3000 model side-by-side in the video.

Another user, Jasoncps, likened the interlacing artifacts to the picture shown below, which is riddled with faded scanlines. He further noted that the issue was most prevalent with dark objects on light colored background.

Right now, we cannot say for sure if this issue is affecting all 3000 owners. It is certainly affecting a considerable amount, though, if the reports on the PlayStation forums are any indication.

It will be interesting if Sony addresses this issue.

Why would it have deinterlacing issues, if the games run in progressive mode? Or did Sony change that, just so the composite cables work for games? That would be pretty lame. Put generally the games run in progressive mode, as they were from the start made for a LCD (which is never interlaced) screen. So there should not need to be any deinterlacing involved. Deinterlacing is also not done by the LCD Panel itself, it would need a separate chip.

Oh you gotta be kidding me! This was the whole reason why I wanted to get the PSP-3000! No more ghosting issues!.. Wow.. well that was dashed for shit now. :(

It's not "interlacing" - from the video it's GHOSTING. Clearly, the response time for the new LCD panel is SLOWER, not faster as Sony claims.

ekmuas says:

the bad interlacing is probably due to higher performance in psp loading blah blah etc.

It was the first thing I noticed when I bought my PSP-3000 a few hours ago! I've made a detailed video of it here:

It also has extreme closeups of the PSP-2000 & 3000 screens, showing the difference in their sub-pixel structure, which explains the "scanline" appearance of the 3k's screen.
