The famous Japan Display Consortium, bringing together Toshiba, Sony, Hitachi and INCJ, now plays records. Sharp unveiled after which there is little a small screen smartphone with a resolution higher than the 400 ppi (pixels per inch), the Japanese see more ... in pixel density, but not diagonally.
When the 300 ppi is already an excellent resolution for smartphones, the Japanese of Japan Display aim higher. They are able to design an LCD panel with the pixel density reached 651 ppi, nearly double the excellent Retina iPhone 4S! However, it is not - again, hopefully - a slab ready to integrate smartphones, especially at a time when their screens like to exceed 4.5 inches: the baby is Japan Display actually a screen of 2.3 inches of HD, 800 x 1280 pixels. If such a screen should be of interest to camera makers, they remain too small for smartphones, especially adapting the format of feature phones. Therefore expected that Japan Display offers the same type of screens in a larger size! Below are samples which you will measure the difference between a slab Retina and another of 651 ppi.
