subject: Iphone 4 Touch Screen Vs Htc And Samsung [print this page] Iphone 4 display technology has 4 times as many pixels compared to previous iPhone models, paceked inside the same 3.5 LED-backlit display, hence producing a display of 960 x 640 pixels display with 326 ppi pixel density.
Again Apple did not do what its competitors have done, they invented a new way to fuse the LCD to the Multi-Touch screen, therefore removing any possibility of air leaking into the gap between the two layers. This produced an effect as if the pixels are painted directly on the glass surface, with a superb viewing angle. Iphone 4 touch screen also has the same IPS technology used in the Apple LED Cinema displays and iPad, as a result the screen has a 800:1 contrast ratio, producing the darkest darks and whitest whites.If you read a lot of documents or images this Retina display will be perfect for that. Almost like looking at real printed paper or glossy printed photos.
iphone 4 Vs Samsung
Samsung seems to have taken exception to a little sidenote made by Steve Jobs during his iPhone 4 announcement at WWDC10 this Monday. While waxing poetic on the virtues of IPS, Jobs let us know that he considers it an entirely superior display technology to OLED, and now the world's biggest display maker has a handful of words to say about it. According to a Samsung spokesperson, the high-res retina display on the iPhone 4 offers only a 3 to 5 % advantage in sharpness over its own Galaxy S Super AMOLED screen, but sucks down a wasteful 30 % a lot more power. Moreover, Samsung believes its screens offer better viewing angles and contrast, and concludes by saying that "structurally, IPS liquid crystal display technology cannot catch up with AM-OLED display technology." And here we thought Samsung and Apple were getting along so well.
Iphone 4 touch screen Vs HTC
Want to see what were speaking about? The above comparison shot arrives from Engadget and compares the iPhone 4s Retina Display with one of the previously cited industry bests, the HTC Evo 4Gs display.
Granted, the HTC Evo 4G is throwing 38% much less pixels at the display than Apple, but even so: look at how those app icons are basically throbbing through the iPhones glass, while the Evo 4Gs display looks like it has been submerged in a thin layer of dirty water.
You see the same effect when you compare it to the iPhone 3GS too.Incredible. This is the new standard for smartphone displays. Sadly, though, this means your brand new iPad is heading to look this muddy once you get an iPhone 4 in your hands too.
