Esteemed Apple analyst Ming-Chi Kuo had earlier predicted that future Apple products might comprise up of a mini LED iPad and MacBook range. For those that don’t know, a mini LED display is thinner and lighter than conventional LEDs and can also produce better quality images. Taiwan-based chip maker Epistar was expected to supply mini LEDs to Apple for future iPads, as well as MacBooks. However, a DigiTimes report now indicates that we might not see mini LED iPads next year and that’s due to several problems being encountered.

According to industry insiders, one reason why a mini LED iPad and mini LED MacBook might be delayed is that this technology still requires up to four years to become mainstream. Although Epistar has teamed up with its subsidiary Yenrich Technology to create mini LED backlighting, it looks like the manufacturer has run into some problems as of late. Apparently there is a host of issues that needs to be dealt with. Since additional mini LEDs are needed than the regular kind to backlight a same-size panel, they incur huge production costs.
