The iPad Air 4 launched last year with an all-new design and Face ID in the Power button. However, the tablet featured an LCD panel and it seems the company will continue using the technology in 2022. Using an OLED panel would raise concerns of quality and cost for Apple and hence, we can forgo our expectations of an OLED iPad Air next year.

Apple analyst Ming-Chi Kuo states in the investor notes that Apple will stick to LCD technology instead of OLED for the iPad Air next year due to the cost and quality concerns (via MacRumors). Kuo previously reported back in March that Apple had planned an iPad AIr with OLED display for next year. Now the analyst has revised his predictions saying that Apple has canceled its plans due to the cost and performance not co-existing with the company's standards.
