Flexible OLED display with chiplets

A method of making a flexible emissive device, comprising:

• (a) providing a flexible rough substrate having a rough substrate surface and defining a display area;
• (b) depositing an organic low-temperature adhesion layer 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;
• (c) providing a plurality of chiplets distributed in the display area and adhering the chiplets to the organic adhesive layer, each chiplet having one or more connection pads;
• (d) bending the flexible rough substrate;
• (e) providing a plurality of patterned bottom electrodes formed over the organic low-temperature adhesion layer in the display area on the bent substrate, each bottom electrode being electrically connected to only one connection pad of a corresponding chiplet;
• one or more layers of light-emitting material formed over the bottom electrode on the bent substrate;
• and a top electrode formed over the one or more layers of light-emitting material on the bent substrate;
• and
• (f) providing a flexible encapsulating layer located over the top electrode and adhered to the rough substrate surface.
