Title:
TRANSFER SUBSTRATE, METHOD OF FABRICATING MICRO LIGHT EMITTING DIODE DISPLAY SUBSTRATE, AND MICRO LIGHT EMITTING DIODE DISPLAY SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2020/062750
Kind Code:
A1
Abstract:
A transfer substrate for transferring an array of a plurality of micro light emitting diodes (micro LEDs) onto a target substrate. The transfer substrate includes a base substrate and an array of a plurality of electroactive actuators. A respective one of the plurality of electroactive actuators includes a ring-shaped frame structure substantially surrounding a central opening, the ring-shaped frame structure made of an electroactive material. The ring-shaped frame structure is configured to undergo a reversible deformation between a first state and a second state upon a change in an electric field applied on the ring-shaped frame structure. A distance between two positions on an inner wall of the ring-shaped frame structure and across the central opening having a first value in the first state and a second value in the second state. The first value is greater than the second value.
