WVGA (480p)
Wide VGA or WVGA an abbreviation for Wide Video Graphics Array is any display resolution with the same 480 pixel height as VGA but wider, such as 800×480, 848×480, or 854×480. It is a common resolution among LCD projectors and later portable and hand-held internet-enabled devices (such as MID and Netbooks) as it is capable of rendering web sites designed for an 800px-wide window in full page-width. A well-known example is the ASUS Eee PC 700 series, but also the Nokia 770, N800, N810 and N900 models.
As of 2010, mobile phones with WVGA display resolution are becoming more common. A list of mobile phones with WVGA displays is available.
FWVGA (480p)
FWVGA is an abbreviation for Full Wide Video Graphics Array which refers to a display resolution of 854×480 pixels. 854×480 is approximately the 16:9 aspect ratio of anamorphically "un-squeezed" NTSC DVD widescreen video and considered a "safe" resolution that does not crop any of the image. It is called Full WVGA to distinguish it from other, narrower WVGA resolutions which require cropping 16:9 aspect ratio high-definition video (i.e. it is full width, albeit with considerable reduction in size). The 854 pixel width is rounded up from 853.333. 480 x 16⁄9 = 853.333. Since a pixel must be a whole number, rounding up to 854 ensures inclusion of the entire image.[1].
As of 2010, high-end mobile phones with FWVGA display resolution include:
Motorola Droid
Motorola Droid X
Sony Ericsson Xperia X10 |
