In the good old days of the Palm OS, the main issue faced by Palm was the odd resultion: a base resolution of 160×160 made scaling to more “common” resolutions was difficult.
Apple has had a similar problem with its 480×320 resolution, but managed to follow it up. Samsung is now at 800×480, and the question is what will follow next (and what is technically possible).
A PR company has now sent me the following:
MicroOLED, a maker of highly power-efficient superior image quality microdisplays for near-to-eye applications, today introduced a new 5.4 million pixel density 0.61 inch diagonal, low power consumption OLED (Organic Light-Emitting Display) microdisplay on silicon for applications demanding high picture quality, such as professional camera and camcorder equipment, night vision systems and head-mounted displays used in surgery.
The ultra-compact 5.4 million-pixel microdisplay with a sub-pixel pitch of 4.7 micrometres by 4.7 micrometres is the highest pixel density OLED microdisplay available today. By doubling the pixel density of comparable products, MicroOLED has eliminated the gap between pixels. With no black matrix present, the resulting image resolution is of the highest quality. This makes the 5.4 million-pixel 0.61 inch diagonal microdisplay most suitable for defense, medical and professional camera applications that demand sharp images with very smooth transitional tones.
As of this writing, no data on availability is given – but it looks like the resolution war can continue!
