Panel technology plays a crucial role in native contrast. For example, OLED (Organic Light - Emitting Diode) panels are renowned for their excellent native contrast ratios. Each pixel in an OLED panel can self - emit light, allowing it to turn completely off to produce a true black. As a result, OLED monitors often have native contrast ratios as high as infinity:1 in theory, as the black level can be extremely close to zero luminance. This is in contrast to traditional LCD (Liquid Crystal Display) panels, which use a backlight. In LCDs, the backlight is always on, and the liquid crystals block or allow light to pass through to create different colors and brightness levels. TN (Twisted Nematic) LCD panels, which are popular for gaming due to their fast response times, typically have native contrast ratios in the range of 1000:1 to 1500:1. IPS (In - Plane Switching) LCD panels, known for their wide viewing angles, usually have native contrast ratios around 1000:1 to 2000:1, although some high - end IPS panels can achieve better ratios.
