Apple is possibly bringing one more piece of its mobile device business in house with the development of its own MicroLED screens.

The screens, which are said to be more difficult to manufacture than the OLED displays Apple currently uses in the Apple Watch and iPhone X, are being developed in secret at a California facility, according to sources familiar with project who spoke with Bloomberg on condition of anonymity. MicroLED displays are potentially brighter and require less power than OLED screens, and also allow for slimmer devices.
