Abstract
Light emitting devices and methods of integrating micro LED devices into light emitting device are described. In an embodiment a light emitting device includes a reflective bank structure within a bank layer, and a conductive line atop the bank layer and elevated above the reflective bank structure. A micro LED device is within the reflective bank structure and a passivation layer is over the bank layer and laterally around the micro LED device within the reflective bank structure. A portion of the micro LED device and a conductive line atop the bank layer protrude above a top surface of the passivation layer.
Claims16
A display panel comprising:
- a substrate;
- a plurality of light emitting diode (LEDs) on the substrate and within a pixel area of the display panel;
- a plurality of Vss tie lines in the substrate and extending across the pixel area of the display panel;
- wherein the substrate further comprises a planarization layer over the plurality of Vss tie lines, and the LEDs are over the planarization layer;
- a patterned dam layer over the planarization layer;
- a metal layer on top of the patterned dam layer, wherein the metal layer is in electrical contact with the plurality of Vss tie lines;
- and
- one or more top conductive electrode layers that electrically connect the plurality of LEDs with the plurality of Vss tie lines.
