Super AMOLED vs LCD outdoors visibility comparison: Omnia 7 vs Optimus 7 vs HTC HD2 vs Galaxy S

Here’s  a follow up to my previous Super AMOLED vs LCD comparison (and here) this time comparing the outdoors visibility of both screen technologies on the Samsung Omnia 7 and Galaxy S for the Super AMOLED and the LG Optimus 7 and HTC HD2 for the TFT LCD. There are lots of pictures (after the break) and all where shot with the brightness set to the same settings on all devices (some are  shot with it set to auto and others to full brightness) so it’s a really an apple to apple comparison. As you will see the Super AMOLED is just a tiny bit better that the LCD on the Optimus 7 (the difference is more noticeable in real life thought) but the HD2 is just a giant mirror compare to the other devices (the HTC HD7 has exactly the same screen btw):

Super AMOLED vs LCD on the Samsung Omnia 7 and LG Optimus 7

Here’s short video update to my previous post about the color banding issue on Super AMOLED screens. Nothing really new here but I just wanted to show you how it looks like in “motion” just in case somebody thought that I doctored the pictures I posted two days ago. The issue here is the RGBG (Red Green Blue Green) PenTile Sub-Pixel arrangement coupled with the insanely high contrast on the Samsung Super-AMOLED panel. To be perfectly clear: according to Samsung’s specs the Super-AMOLED screens are 24bit panels (don’t know about the RGB TFT LCD on the LG but I guess that’s it’s just a 18bit panel that does 24bit with dithering) but I don’t know if Windows Phone 7is being rendered in 16bit or 32bit. If it’s the former, then moving to 32bit could partially fix the problem but Samsung can also do some adjustments to diminish the issue too. video after the break:

The problem with Super AMOLED screens: Nasty color banding

Samsung’s Super AMOLED screen panel is gorgeous, especially when displaying  Windows Phone 7′s Metro UI (with the drak theme) unfortunately there are several ugly drawbacks. First, you have to live with fuzzy text because of the PenTile Matrix Sub-pixel arrangement. Secondly, you will witness sever color banding, thanks in parts to the same PenTile Matrix (it is RGBG compared to a regular RGB lcd…) and also to the extremely vibrant and high color contrast of the screen. I took two photos to show you how ugly it can look like on the Samsung Omnia 7 vs the regular TFT LCD screen of the LG Optimus 7. This is really a problem especially for developers who now have to pay close attention to the assets they are using when building their applications. I’m not entirely sure if the OS is currently running at 32bit color depth but if I had to guess I would say that it is probably set at 16bit (could be wrong thought). Moving up to 32bit could potentially diminish the problem a bit on Samsung’s AMOLED screens. Samsung can also tweak the amplitude of the modulation of the sub-pixels to reduce the problem. One more picture after the break:
