According to reliable Apple analyst Ming-Chi Kuo (via MacRumors), these new devices will have a new type of advanced display called Mini LED. We've seen something similar in Apple's Pro Display XDR (which still isn't available for purchase), but that device only has 576 LEDs, while these new iPads and MacBooks will have around 10,000 LEDs, Kuo claims.
Mini LED is one of several display technologies, alongside OLED and Micro LED, looking to become the new standard for consumer electronics. OLED is great but still suffers from burn-in problems; Micro LED is potentially the most advanced tech but is still in its infancy, and Mini LED offers image quality similar to OLED but doesn't suffer from burn in, and allows for thinner and lighter product design.
Kuo believes another reason why Apple will choose Mini LED is to reduce its dependency on Samsung as its OLED supplier. In contrast, LG Display, among other companies, will supply the Mini LED displays for the new iPad and MacBook, Kuo says.
According to Kuo, this new iPad will have 10-12-inch displays, while the MacBook will have a 15-17-inch display size.
The new iPad should come first — either in late 2020 or early 2021, while the MacBook is planned to arrive either in the first or the second quarter of 2021.
