What is the difference between the mini LED screen used in the new iPad Pro?

At one o'clock in the morning on April 21, Apple held a special event that brought us the new iPad Pro 2021. In addition to upgrading to the latest M1 chip, the screen of the iPad Pro 2021 is also a major focus of this upgrade. The iPad Pro 2021 12.9-inch version uses a mini-LED screen, and the display effect will be significantly improved. Traditional LCD screens are relatively common. At present, most monitors, TVs, and notebooks use LCD screens. In addition, the iPad Pro 2021 12.9-inch screen supports a full-screen brightness of 1000 nits and a peak brightness of 1600 nits. Another more common one is OLED screens, and most mobile phones currently use OLED screens. OLED screens can achieve pixel-level dimming because of their self-luminous characteristics, and have obvious advantages in contrast. It is generally difficult for OLED screens to guarantee high sustained peak brightness. While having the advantages of OLED screens, Micro LED screens have replaced self-luminous materials with inorganic substances, which are more durable and do not have to worry about lifespan and other issues.
