Screen Size
 

Seeing this next to an iphone still makes the screen look tiny. I wish they would have come out with a windows phone that had a large display like the iphone. Still, I'll most likely be getting a touch pro when it comes out.

Re: Screen Size
 

screen resolutions are different. touch pro has 640x480, iphone has the 320x240 i believe.

Re: Screen Size
 

Lawl @ iPhone having 320x240!

320x480 I believe. Its widescreen after all!

Re: Screen Size
 

Yes it [iPhone] has a 480x320 resolution but it's also the fact that the screen supports 16 Million colors vs. 65,000 on every WM device and it's made of glass not plastic (increases clarity, better brightness).

Re: Screen Size
 

This has been a big complaint for me, the iphone can handle so many more colors, and it definitely is an advantage... but at the same time, these new devices (x1, touch, touch pro) have insane pixel densities. I really dont know which one wins out.

Re: Screen Size
 

The human eye can't even distinguish such high color counts, and the high count just increases RAM usage anyway, so I don't know why some are so concerned about it.

In any case, would be nice to have a 3.x" screen (I'm thinking 3.2" like the Zune would be great), but I'm not too greedy about it as long as the screen it has is clear and easy to see and as long as text isn't microscopic.

Re: Screen Size
 

Humm, well here I am thinking about a Sony Cliq. That thing was small, but man oh man I could catch the clarity of that screen from a far.. The resolution was awesome.

I am hoping, (and by the looks of the pictures posted of the screen, I can already tell, it's almost like black print on white paper.) the screen resolution will look at least as decent.

Also as a comparison, take an HTC with the standard 240x320 screen size and compare it to let's say some slider Nokia's screen.. You seen text and web browsing on that "smaller" screen? I can say imho it's clearer, more visibly readable..

Now I hope the on screen keyboard matches the resolution and doesn't hog up the viewable area.. Quite annoying not being able to see what you're typing.

I was of this same idea, until I just looked it up to back you up on that statement. I thought we only distinguished 4096 colors, but it seems I am wrong according to this answer;

Dear Yahoo!:

How many colors can the human eye perceive?

Shelby

Dear Shelby:

Color is how our eyes and brain interpret light. Our eyes can only see radiation with a wavelength of 380 nanometers to 740 nanometers. This is called the visible spectrum of light. Sir Issac Newton listed the pure spectral colors we see in light as red, orange, yellow, green, blue, indigo, and violet.

But "Roy G. Biv" isn't the only name in town when it comes to what colors exist. In 1790, researcher Thomas Young said the human eye sees only three colors -- red, blue, and yellow -- and every other color was just a combination of these primary colors. In 1878 Ewald Hering posited a theory of four unique hues of red, green, yellow, and blue, which, when mixed with white or black, represent all the possible colors humans can process. Useful knowledge for painters and printers perhaps, but it doesn't quite answer your question.

The problem is that nobody really knows exactly how many colors the human eye can see. The closest researchers can estimate is millions and millions. Scientific experiments have shown that humans can discriminate between very subtle differences in color, and estimates of the number of colors we can see range as high as 10 million.

Of course, every person's eyes perceive color a bit differently, and every culture has its own names for colors so coming up with an exact number may not be possible.

Re: Screen Size
 

Almost everything we have printed on paper, even from your computers printer, is "4 color printing"

Re: Screen Size
 

not a fair comparison.... the dpi of modern printers is insane and these dots blend together much better.

Re: Screen Size
 

If you've ever worked in a pre-press environment or looked at a Pantone swatch book you know that 4 color process printing definitely has limitations in accurately producing many colors. Printing is a totally different ballgame, though. You are producing color using reflected available light which is totally different from a backlit LCD panel.

Re: Screen Size
 

Does anyone know if the diamond and rapheal screens are gonna be scratch resistance like iphone ?

Re: Screen Size
 

I was also wondering this

Re: Screen Size
 

i know this been around somewhere, but i seen different answers everywhere! is the screen capacitive or a resistive touchscreen????

Re: Screen Size
 

The display is resistive, but the "buttons" under the display are multi touch capacitive

Think of it as having two touchscreens on one phone, one covers the pixels and another below that

Re: Screen Size
 

Go look up real close at a tube style color TV. Only 3 colors, I think, RGB ?

Re: Screen Size
 

Yes, indeed. Not to stray too far off topic, but take a look at this: http://www.dlp.com/projectors/brilliant_color.aspx TI is using RGB and CMY(with K being the absence of light).

Re: Screen Size
 

THis is not what is being discussed when we say 65536 colors. Most (all?) color displays are RGB at heart. Each pixel is created from a red,green and blue subpixel. In early systems, like CGA,the monitor had a digital input. What that means is that each color could be either on or off. That makes a total of 16 different combinations,or 16 colors.
More modern vga type CRT monitors have analog inputs and can display an infinite number of colors per channel. The video display hardware however is digital in nature and deterimines the number of colors. If there are 8 bits per color,thats 256 colors per channel or a total of over 16 million colors. Many adapters support 32bit color in several variants,such as 10bits per pixel with 2bit transparency,or 8bits per channel with 8bit transparency.
Modern monitors however are mostly LCD displays. These displays are digital by nature. The display itself will be able to handle a particular bit depth. Some displays will handle 8bits per pixel (24bit color) others will handle only about 65k colors. In many cases you wont notice the difference. Ive seen LCD projection TVs that look very good under most circumstances yet only display 65536 colors. With monitors and TVs analog video,or higher bit depth digital video (DVI or HDMI) are converted down to whatever the LCD can display.
64 thousand or 24 million colors sounds pretty good so you might wonder why alot of scanners have 10 or 12bits or more per pixel of color resolution (as well as many professional video and image formats) The reason is that under some circumstances you will notice the difference. In a normal photograph or tv show you might not notice. However if you make a gradient on screen,from light green to dark green,you will notice some banding. In fact,on the cheaper TVs with lower color resolution displays you see this in certain places if you know what to look for. Look for dark scenes with alot of lense flare effects. In these scenes you will see color banding around the lights. In 24bit color its not as apperant,but under some circumstances it can be seen. (but you really have to look)
On a pocket PC you might ask whats the point of being able to display any of 24 million colors when the display only has about 300,000 pixels. The problem is not displaying 24 million colors but displaying for instance 256 levels of red to make the shadows on a rose petal look good. While it woul d be nice to have a 24 bit display,the display on the pocket PCs is fine. I rarely notice any of these issues,and even if I do its really not that bad.

Vision uses tristimulous color perception. This means color is perceived as relative intensities of red, green and blue. These color ranges are broad and have slopes that overlap at the boundaries. This is how we can have a RGB display system for additive color (or CYM for subtractive) and see a range of colors. For example the wavelength of light we perceive as yellow falls on the overlap of red and green perception and registers as equal intensities of red and green. We can perceive that same color by using a display that is emitting red and green light with equal intensity. It's not really making the single wavelength yellow light but rather fooling our perception into thinking that it is. This also shows the limitations of color perception in that we can't tell if the yellow is a pure wavelength of light or a mixture of wavelengths.

The spectral width of the red, green and blue light from the display will determine how deep the colors can be. If the red has energy in the green and blue spectum, then the saturation of the red is reduced. The quality of the color filters in a LCD display determine whether the display looks dull or vibrant.

Another element of visual perception is that it is logarithmic to intensity, which is also true of aural perception. This means that vision is more sensitive in darker areas and less in brighter areas. LCDs have a more or less linear change of intensity in relation to the signal that is fed to it. When the amount of bits are reduced we start to see the quantized steps as banding in the darker areas.

The iphone displays are IMO superior to the ones HTC uses. Video and pictures looks good. Unfortunately for the iphone all that glitters is not gold.
