First, we’ll take a look at the display. The new, ClearVision display used in the F3 not an LCD screen. It is 'electronic paper' developed by US-based E Ink. that doesn’t need power to constantly display an image on the screen—it only needs a little charge when the text (or whatever) needs to be changed. The display stays on even when the battery is pulled out! Hence, the battery life is automatically prolonged as conventional LCD displays are one of the most power hungry component of the modern mobile phone. Also, another added benefit of this technology is that it’s easily readable in harsh sunlight as well, since it’s quite basically just paper. You can read more about the technology here. We tried it out in different lighting areas and noticed that the readability is very impressive in all areas, though the center column of the phone gets a little dim because it has two columns of low-power LEDs on either sides of the phone’s front. These LEDs also illuminate the keys in the side columns well, with the center column being dimmer.
On the other hand, the display isn’t any standard 128x160 or even 128x128 pixel resolution that most low-end phones have these days. It’s a two-line, digital clock-style display with a few icons around it. This is partly an exercise in cutting costs, and partly aimed at making the display more accessible to illiterate users who would prefer pictures to text. The pictures part works, and the larger display of numbers is also easier to read, but I think it’s really inconvenient to read text in that digital clock-style display. Accessibility should make it easier for people to read the text, not to learn to decrypt seven-segment. A lot of the target users may already have seen or used phones with monochrome displays that show sharper, more readable text.
