  • Low cost micro OLED structure and method
    Patent number: 11158690
    Abstract: A method of manufacturing a display system includes forming a display element having a display active area over a silicon backplane, forming a display driver integrated circuit (DDIC), and bonding the display element to the display driver integrated circuit (DDIC). The display active area may include a light emitting diode such as an organic light emitting diode (OLED). Separately forming the display and the display circuitry may simplify formation of the OLED and allow for a higher density control interface between the display and the DDIC.

  • AMORPHOUS OXIDE SEMICONDUCTOR THIN FILM TRANSISTOR FABRICATION METHOD
    Publication number: 20130127694
    Abstract: This disclosure provides systems, methods and apparatus for fabricating thin film transistor (TFT) devices. In one aspect, a substrate having a source area, a drain area, and a channel area is provided. Metal cations are implanted in the oxide semiconductor layer overlying the source area and the drain area of the substrate. The metal cation implantation forms a doped n-type oxide semiconductor in the oxide semiconductor layer overlying the source area and the drain area of the substrate.
