Ez egy új technológiai trükköt használ, nem működik egy-az-egyben az hogy leosztod 3-al mind a magasságot/szélességet. Bővebben. Each pixel can be black-and-white or a color-- that is, one predefined color, not just any color. This is done through a clever trick of polarization and filtering that makes the color subpixels work as monochrome pixels in reflective mode. When backlit, they produce color whether you want it or not.
The true color resolution is not more than 600 x 450 (that is, less than VGA resolution). The apparent/effective resolution may be somewhat higher, but this gets complicated.
The human eye has higher native luminance (brightness) resolution than chrominance (color) resolution. This characteristic is leveraged to great advantage in everyday consumer products.
DVDs, for example, have a luminance resolution of 720 x 480 pixels, but a chrominance resolution of just 360 x 240. Similarly, a 4-megapixel digital camera gets brightness information at 4 million sensor sites, but it only gathers "blueness" or "redness" information across groups of 4 sites-- so its color resolution is just one megapixel in this sense.
These are not problems for DVD or digital-camera image quality because human eyes couldn't see better color resolution anyway. But we still ought to make our comparisons fairly. The OLPC display offers better quality for color images than a good DVD, but it won't be anywhere near as good as a typical XGA (1,024 x 768-pixel) laptop display..
Ugye, kinek mi az effektív felbontás. De mivel ez nem egy 17-es kijelző, hanem egy 7.5-es, így ez nagyon szép felbontás tőle. Szerintem a legegyszerűbb ha fotókat nézel róla. Úgyhogy a hiszem ha látom fog győzni.
