The advent of display technology has paved the way for the continuous evolution of the monitor, whether it's for computers, television, mobile devices or any device that has a display. The current contenders for top-tier technology being used for display devices includes Super LCD 3 (SLCD3) and Super AMOLED. It should be noted that LED displays are actually just a kind of LCD display that use LED lights as backlight illumination. The quality of a monitor's performance is assessed using a few key factors: Aspect Ratio: This is the relation of the vertical length to the horizontal length of the monitor (e.g. 16:9 or 4:5) Display Resolution: Also known as dots per inch (DPI), this determines the number of pixels per linear inch. The maximum number of pixels is determined by the dot pitch. Definition: This portrays the number of pixels the display screen can accommodate. Size: This aspect is determined by the display screen’s diagonal measurement. Dot Pitch: This is the distance between each pixel in every square inch that's displayed. The shorter the distance, the sharper and clearer the images are.
