Pixel density

Pixel density - The pixel density of a display represents the number of pixels over an area of one inch. It’s measured in “pixels per inch”, or ppi. The higher the number, the more detailed and good-looking the display is.

Technology

Technology - There are two main screen technologies currently used in phones and tablets: LCD and AMOLED. The former usually features a light source and liquid crystals, while the latter is based on organic light-emitting diodes. Newer LCD variations like IPS-LCD and Super-LCD allow for very accurate color reproduction and very wide viewing angles, where no significant image quality loss is observed. Current AMOLED screens differ in such a way that they can exhibit much more saturated colors (sometimes too much) and incredibly high contrast levels, which is due to black color being completely black in AMOLED displays.

Positioning

Positioning - This field shows the positioning systems supported by the device. There are three main types: GPS, A-GPS and GLONASS. GPS - This is one of the most widespread global positioning technologies, developed and maintained by the U.S. government. It uses satellites in order to detect your location. Works best in clear weather. A-GPS - A-GPS stands for Assisted GPS and is the industry standard for positioning and navigation. “Assisted” means that it can use local wireless networks, in addition to satellites, for quicker and more precise localization. GLONASS - GLONASS is a global positioning system, developed by the Russian Federation. It’s very similar to GPS, but isn’t so popular in cell phones.
