If you notice the "BlackHawk" patent in earlier posts there is talks about "OLED" ... This will fix any color band issue forever haha OLED is what DSL/Cable is to 56k

    You are 100% correct. The reasons for the display weaknesses in the Storm are a combination of hardware and software; but what it boils down to is that RIM used a cheaper 16-bit LCD panel in the Storm, which limits it to 65,536 possible colors.

    Unfortunately, most images with gradients are designed to be shown on a 24-bit display at minimum, as they are comprised of 16.8 million possible colors. While there is no possible way for totally compensating for the vast amount of missing colors, some dithering algorithms are better at smoothing things out than others. It's obvious that RIM is improving this, but there's no possible way to completely eliminate it.

    The iPhone has an 18-bit display (262,144 possible colors) so it is easy to see why it has less color banding visible to the naked eye. This is STILL way lacking compared to modern PC displays (24/32 bit) so there will STILL be color banding on some images, just none that is visible to the naked eye on a small screen.

    As for technologies such as AMOLED and OLED, they will virtually eliminate this problem, as they are capable of 16.8 million colors, thus no dithering algorithm is necessary.

    NOTE: Cheaper PC displays exhibit color banding issues as well. The reason for this is that some of them use a less expensive panel that causes images to be dithered. Very few LCD monitors display true 24-bit color anyways, one needs an old-school CRT for that.

    Not to change the subject but does anyone know what the Storm 2 will have? as far as if it's going to b 16bit or more?

    Not 100% sure, but the spec list on pdadb.net says it has a transmissive LCD with 65536 "scales", so that translates to 16-bit.
