FLEXIBLE OLED DISPLAY WITH CHIPLETS

摘要

A flexible emissive device, includes a flexible rough substrate (10) having a rough substrate surface and defining a display area; an organic low- temperature adhesion layer (30) formed on the rough substrate surface, at least a portion of the organic low-temperature adhesion layer having a thickness greater than or equal to five microns; a plurality of chiplets (20) distributed in the display area and adhering to the organic low-temperature adhesion layer, (30a) each chiplet having one or more connection pads (24); a plurality of patterned bottom electrodes (12) formed over the organic low-temperature adhesion layer (30) in the display area, each bottom electrode being electrically connected (13) to only one connection pad of a corresponding chiplet; one or more layers of light-emitting material (14) formed over the bottom electrode (12); and a top electrode formed (16) over the one or more layers of light-emitting material; and a flexible encapsulating layer (50) located over the top electrode and adhered to the rough substrate surface.
