Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen. The resolution is given as a compound value, comprised of horizontal and vertical pixels.
Pixel density is a measurement of a screen's resolution, expressed as the number of pixels per inch (PPI) on the screen. A higher pixel density translates into more clarity and sharpness for the images rendered on the screen, thus improving the quality of the viewing experience.
This helps to reduce the reflection from your device.

IPS (In-Plane Switching) is a technology used for LCDs. It was designed to overcome the main limitations of conventional twisted nematic TFT displays: limited viewing angles and low-quality color reproduction. PLS (Plane-to-Line Switching) is a type of IPS screen developed by Samsung, with increased brightness and lower production costs.
A nit is a measurement of the light that a display emits, equal to one candela per square meter. Brighter displays ensure a screen's contents are easy to read, even in sunny conditions.
OLED (Organic Light-Emitting Diode) displays are formed of organic materials that emit light. They have higher contrast ratios and wider viewing angles compared to LCDs. AMOLED and POLED are types of OLED displays.
