OLED is an upgrade in LED display technology, and the response time of OLED is faster than that of LED, which indicates that it can achieve a higher refresh rate, which effectively reduces motion blur and provides a smoother picture transition effect. However, OLED displays are more expensive to manufacture than LED displays, and this higher cost is usually passed on to consumers, resulting in higher prices for devices based on OLED technology and, of course, better OLED displays.
