Abstract

Embodiments describe a display integration scheme in which an array of pixel driver chips embedded front side up in an insulator layer. A front side redistribution layer (RDL) spans across and is in electrical connection with the front sides of the array of pixel driver chips, and an array of light emitting diodes (LEDs) is bonded to the front side RDL. The pixel driver chips may be located directly beneath the display area of the display panel.
