| The 800x480 pixels look fantastic! ![]() Opera 9.;5 browser with flash support looks better on the Xperia than Touch Pro or Safari. Xperia has a higher resolution than the Pro or the iPhone. ![]() Look at post #10 http://forum.xda-developers.com/showthread.php?t=422137 Developers are going to have fun with the XPERIA. . |

| There is a lot of misunderstanding about what makes a display a good display. I want to put my 2 cents on this thread. In 1979 I was programming systems with no fonts, we have to design the fonts pixel by pixel, the Apple II used a Regular TV as monitor. it was not digital, pixels (dots) were analog and they blur with each other and every pixel was only 2 bits deep for color. (iPhone is 32 bit deep) At that time a single character to be readable needed a minimum of 6 to 8 pixels wide (about 1 cm). Obviously you only can put very small amount of info on the screen. I want this to be un-bias and I will address just the physical characteristics of the different displays. The factor that affect the quality of detail, the sharpness of text and graphics and the readability of text are : Density, resolution, Screen size, color (I won’t discuss here Luminosity and contrast ratio) -The most important factor for a detailed and sharp screen is DENSITY -The factors that affect the density are RESOLUTION and SCREEN SIZE -the bit depth of pixels (Amount of colors) contributes the appearance with tonality and fidelity Let’s see some examples: …....….…....Screen….Sq in…..resolution....Total…..….pixels in…..…linear ….......….....Size………Area….. Ht x wd……..Pixels…....Sq inch….....dpi XPERIA…......3.00…...4.32…..800x480......384000….. . 88889……...333 Touch Pro….2.80…….3.87…..680x480......326400…...84341….… ..316 iPhone……...3.50……..5.88…..480x320.....153600…....2 6122……...171 Omnia……....3.20…….5.00…..400x240.......96600…....1 9200……...160 Screen density is measured with dpi (pixels per inch) or dpsi (pixels per square inch of screen). Higher dpi just means more data of information per line therefore better detail and sharper screen. Less dpi is less information data per inch therefore less detail or a more pixilated screen. Both Touch Pro and Xperia with 329000 and 384000 pixels to play with and about the same high density dpi have about the same high quality of text and graphics. BUT the Xperia can show more information (15%) because of the larger screen. Therefore if the touch Pro wants to show the same amount of info as the Xperia the graphic and text detail must be reduced. But to the naked eye the difference is minimum. But if you compare with the iPhone with only 153600 pixels, low density 171 dpi the detail and sharpness of text and graphics per inch is noticeable inferior to Xperia and Touch Pro. The compensating factor in the iPhone is the larger screen that allows still show enough info and the bit per pixel colors also helps with better tonality and faithful colors but still with inferior detail and sharpness. The Samsung Omnia with only 96000 pixels per square inch and a bare density of just 160 dpi, graphics loose a lot of detail and because the screen is relatively large looks very pixilated and small text is very difficult to read. In general assuming a minimum of 8 pixels per character based on the respective resolutions in landscape mode : Experia will show 100 characters, Touch Pro 85, iPhone 60, and Omnia 50 This means that Xperia and Touch Pro can duplicate the number of pixels per character to 16 pixels and to display the same number of characters than iPhone or Omnia. THEREFORE the display will be with better detail more readability. The opposite is true for the Omnia and iPhone to display the same amount of information as the Xperia or the Pro they have to reduce the details of fonts and graphics making them less readable. The graphics of hardware, software and the actual application are a totally separate discussion. |

| wow thx for that man. that was actually very informative and after reading it several times i actually do understand it. even though the numbers suggest little difference between the 2 screens, i like to know that the xperia is infact still superior :P it all about the epeen factor.... ... though really once your lvl 60 its all about looking cool. |

When people write apps for a windows desktop, the UI is usually written to dynamically resize to the window size. Therefore, when a window is not maximized and you resize it, the UI dynamically resizes relative to the size of the window. On the WM side though, developers have gone far too long assuming the window will be 240x320. Then VGA came out and some just update their app to support a higher dpi. Its about time all WM apps were written more like desktop apps where the UI targets a DPI and dynamically organizes based on the current screen size, rather than targetting a static pixel by pixel size.
