So im in the market to purchase a smartphone namely the nokia e71 i havent have much experience with smartphones i have only had the nokia n90 and the sendo x wich i loved till it died any way i was all ready to purchase the e71 when i saw the screen size its obviously larger then the n90 but with less pixels so how does that effect the over all image i mean what good does it do to have a large screen if it looks horrid im hoping some one can tell me how the e71 compares in resolution does the image look clean and crisp as i have yet to see one in person im ify to spend money on something i might not like
what is the Correlation beween screen size and pixels?
Physical screen size and number of pixels has no direct relationship.
There are phones with the same display pixel resolution, but different physical screen sizes.
E.g., all these devices have the same 240x320 pixel (QVGA) resolution display, but different physical display dimensions (i.e., the pixel size is different):
- 5320: 2" display
- 6210: 2.4" display
- N95: 2.6" display
- N96: 2.8" display
In the case of the E71 vs. the N90, the E71 has a QVGA landscape (320x240) pixel screen at 2.36" and the N90 had a 352x416 pixel screen at 2.1".
So, in effect, the N90 had much, much smaller pixels.
For regular phone use that virtually no difference, but, e.g., photos would appear much sharper because of the smaller pixels.
And of course, the display or pixel size of the display has no impact on, e.g., what kind of photos or videos the phone takes. That is determined by the camera sensor, camera lens and camera software.
In any case, Nokia used the 352x416 resolution display only in a handful of models a few years ago, and then switched over to the more standard QVGA.
