We previously reported on the fact that at least one of Sony Mobile’s upcoming 2013 flagship is likely to feature a 5-inch (1920 x 1080) display with an impressive 443 PPI. The display will be developed by Japan Display Inc (JDI) and the press release published in early October suggested it would be a TFT-LCD IPS display in RGB configuration.
However, a more recent press release from JDI regarding display prototypes for vehicles suggests that a WhiteMagic display could be inbound. It talks of a 5-inch 1080p display with 438 PPI and “low power consumption that is approximately 50% less by utilizing an RGBW pixel structure”. This display also includes an “integrated touch function (without cover glass)”, probably similar to Sony’s sensor-on-lens touch screen technology.
As a reminder, a WhiteMagic display has the red, green blue and white (RGBW) sub pixels aligned horizontally. The additional white sub-pixel significantly increases display brightness compared to normal LCD and OLED screens. The technology can be used to double the brightness or to save 50% of the backlight power, as suggested by the JDI press release. There’s no guarantee WhiteMagic will appear in this 5-inch 1080p display, but it looks like the technology is there if Sony wants to use it.
