The 960 by 480 panels in these LCDs only have 320 x 240 logical pixels. It’s my understanding that you cannot draw to this screen at any other resolution. That is, in CRT terms, you cannot resolve more than 320 distinct white and black lines on that screen. https://en.wikipedia.org/wiki/Television_lines. Academics please respond. The factory arrives at that stupid number by counting all subpixels. Dividing by three to make way for R, G, B, subpixels, we arrive at 320×480. Now here is the weird part. It’s a “RGB-Delta” array, basically this means there is a top RGB set and a lower RGB set that is offset to the side by some amount. Somewhere out there you can find an academic paper with “RGB-Delta” searching, I saw one with good pictures, but I can’t find it now. The effect of this is that straight lines white lines become tiny little back and forth zig-zags. The screen is similar in nature to the one in the GB Boy, only scaled to a higher DPI. The supposed advantage of this subpixel rendering method is that it reduces chroma artifacting. This is seen as a feature in the video camera market for which these screens were originally produced. So finally, we arrive at a 320x240 logical resolution, except now all your crisp squares turn into these little diagonal zig-zags. Now, all that said, you can only really notice this stuff if you bring it close in when you play. It’s great to just put it to fullscreen bilinear and rock out. It has enough vertical and horizontal resolution to display every line of SNES, MD, and NES games, and it runs at 60 hz vsync no tearing. It’s just not as good as V- or H- RGB stripe if you’re into the ‘classic’ lcd look. |
