Abstract

A micro-transfer printed high-resolution inorganic light-emitting diode (iLED) display includes a display substrate and a plurality of pixels disposed over the display substrate, each pixel including a pixel controller disposed or formed in or on a pixel substrate and controlling one or more iLEDs disposed or formed in or on respective iLED substrates. The one or more iLEDs are disposed above or below the pixel controller in a separate layer from the pixel controller. The display substrate, the iLED substrate(s), and the pixel substrate are all separate, independent and distinct, and the one or more iLEDs and pixel controller are each separate devices.
