OLED stands for Organic Light Emitting Diode, which is a type of display technology that uses organic compounds to produce light. OLED displays are known for their deep blacks, high contrast ratios, and wide viewing angles.

Refresh rate refers to the number of times per second that a display refreshes its image. A higher refresh rate results in smoother animations and less motion blur.

Adaptive refresh rate is a feature that allows the display to adjust its refresh rate based on the content being displayed. For example, if you’re watching a movie, the display will lower its refresh rate to conserve battery life. If you’re playing a game, the display will increase its refresh rate to provide a smoother gaming experience.

In summary, OLED is a type of display technology that offers deep blacks and high contrast ratios. Refresh rate refers to the number of times per second that a display refreshes its image.
