OLED stands for Organic Light-emitting Diode, and it is one of the three display types available for laptops, along with TN (Twisted Nematic) and IPS (In-Plane Switching) panels. OLED displays use organic compounds that emit light when an electric current is applied, unlike LCD displays that use a backlight to illuminate the pixels. OLED displays have several advantages over LCD displays, such as higher contrast, wider viewing angles, faster response times, and lower power consumption. However, OLED displays are also more expensive, less common, and more prone to burn-in than LCD displays.
