Universal Display makes key technology and owns some OLED intellectual property; investors are likely concerned Apple’s MicroLED technology will eventually replace Universal Display’s technology. There, about 300 engineers are designing and producing MicroLED screens for use in future products. Another facility nearby houses technology that handles so-called LED transfers: the process of placing individual pixels into a MicroLED screen. The latest MicroLED Apple Watch prototypes aren’t fully functioning wearables; instead, the screen portion is connected to an external computer board. Each piece comes from what is known as a “donor wafer” and then are mass-transferred to the MicroLED screen.
