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.
2.has an LED-backlit display
Uses LED backlighting, resulting in better image quality, more vibrant colors and richer blacks.
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.
The bigger the screen size is, the better the user experience.
5.displays 3D with glasses
The screen can be used to view 3D images with special glasses. The advantage of these screens is that they provide wider viewing angles compared to devices that don't require 3D-compatible gear.
6.has micro or local dimming
Local dimming is when sections of the LED array are turned off or dimmed to help produce the deep blacks and higher contrasts.
