A new report from Czech Republic-based SuperiPhone (Translated Link) claims to have confirmed the resolution of the fourth-generation iPhone’s display at 960 x 640. Using a microscope, the publication compared a display component supposedly meant for the fourth-generation iPhone to the displays of an iPhone 3GS, iPod touch, and Google Nexus One.
Based on their results, the report claims that the display does have a resolution of 960 x 640, which results in a density of 320 ppi, and also uses the same IPS technology found in the iPad. John Gruber of Daring Fireball first suggested that the next iPhone would sport a 960 x 640 display in March, later explaining that the quadruple resolution—compared to existing iPhones and iPod touches—would allow current applications to be upscaled with little to no discernable difference in quality.
