Abstract
Provided are integrated organic light emitting diode (OLED) display apparatus and methods for making the same. In one example, the apparatus includes driving logic on a first substrate of a first die, a plurality of pixel circuits on a second substrate of a second die, and a plurality of OLEDs above the plurality of pixel circuits. The first substrate is made of single-crystal silicon or a compound semiconductor. The second substrate is made of single-crystal silicon or a compound semiconductor. Each OLED corresponds to a respective one of the plurality of pixel circuits. The second die having the plurality of pixel circuits and OLEDs is mounted on the first die having the driving logic. Each pixel circuit is electrically connected to the driving logic through at least one of a plurality of vertical interconnect accesses (vias) penetrating the second substrate of the second die.
